Embodiment

Referring to Fig. 1-2 2, the first embodiment of the present invention is related to one kind and is configured to the tubular element form as pipe 10 Elongated hollow structure, and the method for constructing in continuous foundation the pipe.

Pipe 10 is composite construction, including inner radial 11 and radially outer 13, two parts 11 and 13 be merged together with Complete structural pipe wall is provided.In the structure, outside 13 is enclosed in protective case 14, and the protective case includes hardenable group Divide 16, the concrete that such as adhesive or outermost top layer 18 are included, outermost top layer 18 can be any suitable material, example Such as geotextiles.Protective case 14 is used for providing pipe 10 protection, and once pipe is possible to what is met with installation situations for resistance Compressive load.

Inside 11 includes neck bush 15, and the layer 17 being made up of resin absorbent material is adhered on a face of neck bush.It is interior The another side of bushing 15 defines the inner surface 19 of pipe 10.Generally, neck bush 15 shows as high smooth table at inner surface 19 Face.For example, neck bush 15 can include polyurethane, polyethylene or other any flexible flexible materials, the material is also It is preferred that it is airtight, and can also be coexisted with the fluid of transmission in pipe 10.Resin absorbent layer 17 can be for example including felt or cotton Beam.

As shown in figure 4, inside 11 is configured to the inner tube 21 formed by the longitudinally oriented strip 23 with vertical side of the edge 25.The quilt of bar 23 It is longitudinally wound into tubular structure to provide inner tube 21, longitudinal edge 25 in syntople provides banjo fixing butt jointing 26.Interior connection Bar 27 is applied to the inner side of inner tube 21, and outer connection strap 28 is applied to the outside of inner tube 21, and two connection straps 27 and 28 are across right On joint 26, continuous Fluid Sealing can be provided between adjacent vertical side of the edge 25.In Fig. 4, for clear original Cause, connection strap 27,28 is shown as separating with banjo fixing butt jointing 26, but they actually connect with banjo fixing butt jointing in practical application Touch.

Inner tube 21 defines the inflatable courage 24 with expansion chamber 29, will then explain its purpose.

Outside 13 is configured to the outer tube 30 for the fiber reinforcement combining structure surrounded by soft shell 31.More specifically, outer Pipe 30 includes the reinforcer 32 penetrated into resin binder.Soft shell 31 is installed with comprising the resin-bonding around pipe 30 Agent, then this will be described in detail.Soft shell 31 can be formed by any suitable material, such as including polyethylene. Shell 31 is held in position in and ultimately forms a part of pipe 10, or can also be after its purpose is completed It is removed.

The fibrous layer that shell 31 includes the outer layer of polyethylene and is adhered in one face, the structure is fibrous layer in face of adding Strong part 32.Fibrous layer provides unsaturated zone, and is finally infiltrated resin binder for the integration of the structure.

The resin material for providing resin binder can be any suitable type；A kind of specially suitable resin material bag Include thermosetting resin, such as epoxy vinyl ester or other suitable resins, and thermoplastic resin system.

Reinforcer 32 includes one or more layers 33 (as shown in Figure 5) of reinforcement fabric 34, and each layer is structured to The tubular layer 35 (as shown in Figure 7) of the surrounding of inner tube 21 arrangement.In this embodiment, there are multiple layers 33, these layers are configured to The respective tubular layer 35 (therefore arrangement around inner tube 21 also as described above) of arrangement close to each other.Any conjunction can be used Suitable mode combines adjacent fibrous layer 33, such as by hot weld chemical bond, and/or is mechanically fixed, such as seam or Nail.

Reinforcement fabric 34 includes the reinforcement fabric for being associated with reinforcing fibre, and the reinforcing fibre has what four axial direction fibres were oriented Characteristic, as shown in Figure 5.Reinforcing fibre includes axial direction fibre 36a and (angle close to tube axis is in, such as the institute of Fig. 3 center lines 37 Show), transverse fiber (be in tube axis is about in 90 degree of angle) and inclined fiber (be in tube axis about in 45 degree Angle).Reinforcing fibre may include glass fibre.Four axial direction fibres are orientated the necessary ring of pipe offer and axial stress is held Carry performance.

The bar 41 that each reinforcing fibre tubular layer 35 is all made up of reinforcing fibre material is constituted, and this has longitudinal edge 43, these edges gather together to form tubular layer 35 at joint 44 in overlapped mode.Overlapping edge 43 with appoint A kind of what suitable mode is installed to together to ensure the tubular moulding.In this embodiment, overlapping edge 43 uses hot melt Binding agent is connected together by sweat soldering technology.In figure 6, for purposes of clarity, between overlapping edge 43 is shown as Separate, but they are in fact in contact with each other to provide joint 44, as shown in Figure 7 in practice.Then by by resin binder Penetrate into reinforcement fabric 34 to realize the structural intergrity of joint 44, tubular layer 35 can be formed by reinforcement fabric.Particularly, resin Adhesive penetrates into overlapping edge 43 and is bonded together them, is initially glued by what hotmelt was set up with supplementing and substituting Close.

Each tubular layer 35 is oriented such that each joint 44 is offset with one another, as shown in Figure 8.In structure shown in the drawings In, it is oriented so as to tubular layer 35 so that the downside 46 of corresponding pipe 10 of the joint 44 towards in building is arranged.This is very It is favourable, because downside 46 is that resin binder is very possible very sufficient to improve between the overlapping edge 43 at each joint 44 Bonding region.

The felt layers 17 that the resin binder of reinforcement fabric 34 is also penetrated on liner 15 are penetrated into, by outside 13 and inside 11 integrate.

Reinforcement fabric tubular layer 35 as previously described it is close to each other arrangement and thus be also arranged close to inner tube 21 after, pipe Shape layer 35 is infiltrated resin binder.In alternative, after the completion of each reinforcement fabric tubular layer 35 is assembled, strengthen knitting Thing tubular layer 35 is infiltrated resin binder.The assembled each reinforcement fabric tubular layer completed can be connected to previous interior reinforcement and knit In thing tubular layer, for example, pass through sweat soldering.It is preferable, however, that do not connect adjacent reinforcement fabric tubular layer so, so that Each layer can free movement toward each other, with transmit load and stress, thus each layer can receive its load share.

Typically, before resin binder is penetrated into, air is removed from reinforcement fabric tubular layer 35.

After reinforcement fabric tubular layer 35 is penetrated into by resin binder, but before the hardening, by the way that fluid example will be expanded Such as air introduces expansion chamber 29, and the inflatable courage 24 limited by inner tube 21 is inflated.This cause inflatable courage 24 towards The radial dilatation of soft shell 31, form and shape are provided to circular outside 13.Particularly, outside 13 shows as the transversal of annular Face.

When inflatable courage 24 moves through compression set 125, the lasting expansion of inflatable courage 24 is drawn along all directions Reinforcement fabric tubular layer 35 is stretched, to improve the circumference stress and axial stress bearer properties of pipe 10.Particularly, the expansion is used for To the fiber prestress in reinforcement fabric tubular layer 35, to improve circumference stress bearer properties, and axial tightening reinforcement is gone back Woven tube layer comes to fiber axial tensioning therein, to improve the tension load-carrying performance of pipe 10.

Soft shell 31 is used for the radial dilatation for resisting reinforcement fabric tubular layer 35, so as to cause reinforcer 32 to bear radially Compression.Using this arrangement, reinforcer 32 is limited in the space 45 between expansion inner tube 21 and soft shell 31.Radially expand The inner tube 21 opened is operated together with flexible shell 31, to limit reinforcer 32, and can also cause the sky of limitation reinforcer 32 Between 45 volume be gradually reduced.This forces the resin binder in reinforcer 32 to be totally immersed in reinforcer 32；That is, The layer 33 for constituting the reinforcement fabric 34 of tubular layer 35 becomes " to soak " completely.Particularly, compression stress also is provided to reinforcer 32, had Resin binder is pumped out resin binder by effect ground by the layer 33 of reinforcement fabric 34, so that resin binder is with controllable and limited Mode be distributed in space 45.One of the present embodiment is special, and characteristic is, the step of transmitting resin binder to reinforcer And the step of resin binder is soaked reinforcer 32 be completely to separate and visibly different behavior.

In addition, being gradually reduced for volume that limitation has the space 45 of reinforcer 32 also necessarily makes air be arranged from space 45 Go out, this has the effect for the infiltration for improving resin binder in reinforcer 32.Shell 31 and each reinforcement fabric tubular layer 35 It is designed so as to the discharge of air.The unsaturated zone limited by the fiber internal layer of shell 31 contributes to this air to discharge.In addition, outer Shell 31 and each reinforcement fabric tubular layer 35 can compartment of terrain is arranged for example in their own length air vent, with It is easy to the discharge of air, as shown in Figure 9.In a kind of structure, air vent 48 can be formed in shell 31 and each reinforcement fabric Perforation in tubular layer 35, for example, penetrate aperture.By this structure, perforation finally can be sealed to ensure pipe by resin binder The sealing integrity of son 10.In another structure, air vent may include to be inserted into shell 31 and each reinforcement fabric tubular layer Port in 35.The port can for example include what is formed by one exposed to the material that resin binder will dissolve or degrade Tubular insert.By this structure, the aperture for accommodating port is finally sealed by resin binder, to ensure the sealing of pipe 10 Integrality.

Soft shell 31 has some elasticity, in order at least compliantly resist reinforcement fabric tubular layer to a certain extent 35 radial dilatation.In this fashion, soft shell 31 can buffer the initial of the radial direction foreign minister of reinforcement fabric tubular layer 35 Stage.In particular, it is desirable to which soft shell 31 has certain elasticity.Soft shell 31 has certain elasticity, and the elasticity is used to improve Control to speed, the speed refers to that gradually increased resin binder rises the speed that pond is gradually impregnated with reinforcer 32.One side Face, if resin binder rises too fast in space 45, then the fiber in reinforcer 32 can not just be impregnated with completely, On the other hand, if resin binder rises too slow in space 45, then the fiber in reinforcer 32 is impregnated with completely Before, resin binder begins to hardening.

The elastic nature for the soft shell 311 installed around reinforcer 32 is used as around thing, for controlling to a certain extent System is applied to the external pressure that resin binder rises pond.The elasticity of soft shell 31 be may be selected, and desired speed is soaked to realize Rate.Tensile force that the elastic force applied by shell 31 is applied to the inflatable courage 24 limited by inner tube 21 provides to a certain degree flat Weighing apparatus.

Inflatable courage 24 is maintained at inflated condition, until resin binder be sufficiently hardened ensure that pipe form and Shape, can then discharge expansion fluid from expansion chamber 29.So as to form pipe 10, the center in pipe is limited by liner 15 Flow channel.

Inner tube 21 can be carried out as a part for the construction flow of pipe 10 or be assembled at the scene.

In the environment of preform inner tube 21, inner tube 21 is transported to scene with the state of contraction.Inner tube 21 can be with any A kind of suitable mode is retracted.Typically, by the way that inner tube 21 is folded into contraction state with folding mode, to provide cross section Compared with compact structure.In structure as shown in FIG. 10 and 11, it is flat that inner tube 21 is shrunk to cross section by a kind of folding mode Flat state, the folding mode defines two longitudinal edge 51 and positioned at the folding part 52 between them.Using this structure, indulge Compact form can be provided to edge 51 with contact located adjacent one another.In structure as shown in figs. 12-15, a kind of Foldable square is used Inner tube 21 is shrunk to the state of flat cross section by formula, and the folding mode defines two longitudinal sidepieces 53 and positioned between them Recessed folding part 54.Using this structure, a longitudinal direction side of each recessed folding part 54 all from the inner tube 21 of contraction is inside Extension.Figure 13 is the cross-sectional view of the inner tube 21 of folded state.In fig. 14, inner tube 21 is in the flat state in part.
