Abstract
The utility model discloses a kind of crossbar contact overlap joint injection moulding clad type geo-grid, it is characterized in that: comprise lateral straps and longitudinal band, intersect to form crosspoint between band, band is provided with the coated node of injection moulding in crosspoint outer cladding; The coated node of described injection moulding is injecting type one clad structure, and wrapped position comprises the corner in crosspoint, the front and back position in crosspoint.
Description
Technical field
The utility model relates to a kind of geotechnical engineering and builds geosynthetics used---crossbar contact overlap joint injection moulding clad type geo-grid.
Background technology
Among the geotechnical engineerings such as geo-grid is mainly used in speedway, railway, airport construction, harbour, fills in the sea to grow grain, water conservancy dykes and dams, after making roadbase backfill soil reinforcement, globality is stronger, sinking not easy to crack and displacement, ensure that workmanship and safety, be one of current first-selected novel geotechnological building materials, be project of vital and lasting importance engineering, provide sound assurance.
Of a great variety for the preparation method of the reinforcement material of geotechnical engineering at present, it uses mechanical property feature, and conform each variant, Plastic mainly contains three classes:
1) plastic tensile class: as unidirectional, biaxial tension Plastics Geogrids, this series products usually with polyethylene or polypropylene for primary raw material, add various auxiliary agent again, sheet material is extruded into by screw extruder, through forcing press, punching is carried out to sheet material, then carry out preheating longitudinal stretching, cross directional stretch forms.This production method equipment investment is huge, and equipment is huge, and production product cost is high, and hot strength is low, and the strong speed of every linear meter(lin.m.) stretching is 50kN.
2) plastics weldbonding class: as drawn polyester band weldbonding grid, polypropylene tension belt weldbonding grid, steel and plastic composite material grid etc., this series products first uses extruder and composite machine head by after plastics and composite material co-extrusion, after being drawn into the band of one fixed width, longitudinal, the orthogonal network of transverse lap again, node place carries out welding (weldbonding) through ultrasonic welding machine again and forms.This product is after welding, and easily original tensile strength of damage band, its vertical, horizontal band cross weld point low in conjunction with peel strength, in construction and transportation, pad easily comes off.
Technology disclosed in current patent, do not relate to the concrete forming method of injection mo(u)lding, and efficiency is low, intensity is low, high in cost of production defect.
Summary of the invention
In order to overcome current deficiency, the utility model provides a kind of crossbar contact overlap joint injection moulding clad type geo-grid, compared with prior art, has the advantage that cost is low, intensity is high.
For reaching above object, the technical scheme that the utility model adopts is:
A kind of crossbar contact overlap joint injection moulding clad type geo-grid, it is characterized in that: the band comprising at least two different directions, intersects to form crosspoint between band, band is provided with the coated node of injection moulding in crosspoint outer cladding.
Further, described band is lateral straps and longitudinal band.
Further, the coated node of described injection moulding is injecting type one clad structure, and wrapped position comprises the corner in crosspoint, the front and back position in crosspoint.
Further, shrinkage pool is provided with before and after the coated node of described injection moulding.The corner of the coated node of injection moulding be positioned at corner, crosspoint and with corner, crosspoint one arc structure, the coated node overall of injection moulding becomes petal.
Further, described band is at least one of polypropylene (PP) tension belt, polyester (PET) tension belt, composite steel-plastic belt, glass plastic composite strip; Strip face has rhombus roll extrusion flower.
Operating principle of the present utility model and beneficial effect show:
The utility model mainly comprises the band (such as lateral straps and longitudinal band) of different directions, and the band of different directions intersects to form crosspoint.
Creation point of the present utility model is just the form of structure in this crosspoint, the structure of employing injecting type of the present utility model, integrated fusion can be carried out with band, and can in the surrounding in crosspoint: corner and front and back form overall structure, substantially increase the intensity in crosspoint.
To sum up, the utility model has the following advantages:
1, efficiency is high.
Because geo-grid is the latticed construction material of the rolling with one fixed width (4m ~ 6m) and length (30m ~ 50m), can adopt in building site large area, if adopt prior art to produce, can not meet a large amount of employing far away.And two lateral straps have been injected in invention employing on full width (4m ~ 6m) simultaneously, once complete coated crossbar contact and mostly be 86 most.
2, cost is low.
From the shape analysis of the coated point of injection moulding, inject the technology of all material volumes much larger than present patent application.
3, node peeling force is high, survivable.
The node peeling force formed by welding is low, and in construction and transportation, pad easily comes off.Present invention employs multistation injecting molding die, and the design of upper and lower module quick-replaceable, to achieve rapidly and efficiently, cost-saving, and substantially increase the peeling force of coated node.

Shown in Fig. 1,2, a kind of crossbar contact overlap joint injection moulding clad type geo-grid, comprise the band 1 of at least two different directions, intersect to form square crosspoint between band 1, band is provided with the coated node 2 of injection moulding in crosspoint outer cladding.
Selector bar belt type as required, the band of the present embodiment be divided into for: lateral straps and longitudinal band, lateral straps and longitudinal band form rectangular unit grid, and the summit of rectangular unit grid is crosspoint.
The coated node of injection moulding of the present embodiment is injecting type one clad structure, and wrapped position comprises the corner (in figure circular arc 4 place) in crosspoint, the front and back position in crosspoint.
For reducing weight, the present embodiment middle part before and after the coated node of injection moulding is provided with shrinkage pool 3, increases " interlocking power " with reinforced earth.
