Speedway or railway are crossed over big rivers or lake and the Hai Shi of width, generally do not adopt bridge, and adopt tunnel, its main cause to be because the tunnel is both economical.At present, also have a kind of more economically, that is exactly an immersed tube tunnel.Build this immersed tube tunnel and not be used in water-bed hole, mine working tunnel, and as long as prefabricated tunnel tube coupling is settled down to the bottom, and the series connection splicing gets final product well.So the construction period of this immersed tube tunnel is short, and the labor and material saving cost is low.But because this tunnel finally still will fall within the bottom, so it has certain requirement to the landform at the bottom.This tunnel is not suitable at water-bed geological conditions bad, and ground just rises and falls the place excessive and uses under water, particularly is not suitable for using in deep-sea with a varied topography.
The object of the present invention is to provide a kind of semi-submersible type tunnel and erection method thereof that suspends in water, this tunnel does not fall within the bottom, so to water-bed geology, landform no requirement (NR), thereby can make water-bed geological conditions bad, the tunnel also can be built in very big, the with a varied topography waters that just rises and falls, ground under water.
Order of the present invention is achieved in that and the invention provides a kind of semi-submersible type tunnel, it is to be formed by prefabricated tunnel tube coupling SG1, SG2, SG3-----SGn tandem compound, its tunnel tube coupling SG1, SG2, SG3-----SGn suspend in water, its underpart all is that rope 1 is arranged, the other end of rope 1 ties up on mass PZ1, PZ2, PZ3-----PZn or the water-bed rock 2 that is placed on different directions, thereby, tunnel tube coupling SG1, SG2, SG3-----SGn are under the acting in conjunction of the tension force of rope 1 and buoyancy of water, be fixed, and suspend in water.
When this kind tunnel sets up, at first with mass PZ1, PZ2, PZ3-----PZn puts into the bottom by design attitude and fastens rope 1 or hole on water-bed rock 2 and fasten rope 1 by design attitude, then with two ends all the tunnel tube coupling SG1 of good seal transport on the water surface that will build pontoon bridge, and there is the other end of the rope 1 of mass PZ1 or water-bed rock 2 to tie up to the bottom of tunnel tube coupling SG1 with being, strain all ropes 1 then, make tunnel tube coupling SG1 dive behind design attitude, fasten all tightropes 1 again, pulling force by rope 1 makes tunnel tube coupling SG1 in place, and fixes; As stated above that remaining tunnel tube coupling PZ2, PZ3-----PZn is in place more afterwards, and fix; Method with bolt or welding is stitched together all tunnel tube coupling series connection then; Remove the sealing at all tube coupling two ends, tunnel at last, make it to become the tunnel of a perforation.
For ease of seeking rope 1, can be before tunnel tube coupling SG1, SG2, SG3-----SGn be in place, end with rope 1 ties up on mass PZ1, PZ2, PZ3-----PZn or the water-bed rock 2 earlier, and its other end ties up on the floating thing made from timber or polystyrene 3.
For being easy to the in place of tunnel tube coupling, at tunnel tube coupling SG1, SG2, when SG3-----SGn is in place, toward tunnel tube coupling SG1, SG2, SG3-----SGn in, add earlier water or with outside be method help tunnel tube coupling SG1, SG2, the SG3-----SGn dive of mass 4, after each tunnel tube coupling is in place, all to fasten tightrope 1, lean on the tension force of rope 1 that its fixed-site is got off; Except that first tunnel tube coupling, after other tunnel tube coupling is in place, also to connects with previous tunnel tube coupling and splice with the method for bolt or welding; Wait all tunnel tube couplings connect full splicing good after, the mass 4 with water in tunnel tube coupling SG1, SG2, the SG3-----SGn or outer system removes again, removes the sealing at all tube coupling two ends, tunnel at last again, the tunnel has just installed.
Because tunnel of the present invention tube coupling do not fall within the bottom, directly do not carry, but suspend in water by ground under water, rely on buoyancy of water to overcome the attraction of the earth to self.Therefore tunnel of the present invention is to water-bed geology, landform no requirement (NR).That is to say that water-bed geological conditions is bad again, surface relief greatly also has no relations under water again, can not influence the installation and the use in tunnel of the present invention.So, just can make the waters that can not adopt immersed tube tunnel over also can build the tunnel.In fact, the advantage in tunnel of the present invention also moreover because tunnel of the present invention does not fall within the bottom, therefore can be saved arrangement and excavation to water-bed ground; Because tunnel of the present invention is to suspend in water, need not bury by any material, therefore can save and bury used worker, material and time.For above-mentioned reasons, build tunnel of the present invention and compare with common immersed tube tunnel, can saving of labor 10%---30%; Duration can shorten 20%---and 40%.
Because tunnel of the present invention suspends in water, be not subjected to not that water surface wave influences, also can be used among the sea so not only can be used for river, river, lake.
Fig. 1 is the elevational schematic view in semi-submersible type tunnel;
Fig. 2 is A---the A section;
Fig. 3 is the scheme of installation in semi-submersible type tunnel.
Describe best implementations of the present invention in detail below in conjunction with each accompanying drawing.
A kind of semi-submersible type tunnel that Fig. 1 is represented, it is to be formed by prefabricated tunnel tube coupling SG1, SG2, SG3-----SGn tandem compound, its tunnel tube coupling SG1, SG2, SG3-----SGn suspend in water, its underpart all is that rope 1 is arranged, and the other end of rope 1 ties up on mass PZ1, PZ2, PZ3-----PZn or the water-bed rock 2 that is placed on different directions.
As seen from Figure 2, tunnel tube coupling SG2 is a circular pipe type, and its inner rail of installing can lead to train.In fact, as not being installed, rail also can be open to the traffic or other vehicle.
When this kind tunnel sets up, at first mass PZ1, PZ2, PZ3-----PZn are put into the bottom by design attitude and fasten rope 1 or on water-bed rock 2, hole and fasten rope 1 by design attitude.After having fastened rope 1, next just the tunnel tube coupling can be installed.
Problem is though the other end of rope 1 does not tie up on any mass, because the proportion of rope 1 is generally big than water, can't lean on the buoyancy of self to float on the water surface.Therefore, on the water surface, be difficult for finding rope 1.For ease of seeking rope 1, before tunnel tube coupling SG1, SG2, SG3-----SGn are in place, the other end that just will tie up to the rope 1 on mass PZ1, PZ2, PZ3-----PZn or the water-bed rock 2 earlier ties up on the floating thing made from timber or polystyrene 3, and then the tunnel tube coupling is installed.
Two ends of tunnel tube coupling SG1, SG2, SG3-----SGn when prefabricated with regard to good seal, so they can swim on the water surface as ship.During installation, these tunnel tube couplings can be dragged to the erecting bed with ship.After the position finds, just should in tunnel tube coupling SG1, SG2, SG3-----SGn, add water or fasten mass 4 earlier.Its purpose of doing like this: be in order to help tunnel tube coupling SG1, SG2, SG3-----SGn dive.
What Fig. 3 was represented is: tunnel tube coupling SG1 is all right position, and fixed the existing tunnel tube coupling SG2 that installing.As seen from Figure 3, there is mass 4 in the outside of tunnel tube coupling SG2 system, and an end of rope 1 ties up on the mass simultaneously, and the other end passes through tunnel behind the annulus of tube coupling SG2 bottom, ties up to respectively on the hoist engine of two ships again.Hoist engine is being strained rope 1.So, tube coupling SG2 in tunnel just can sink in place in the acting in conjunction of making a concerted effort that mass 4 and hoist engine are executed.Tunnel tube coupling SG2 in place good after, tightrope 1 is fastened, so, rely on the tension force of rope 1, tunnel tube coupling SG2 just has been fixed.Afterwards, with the method for bolt or welding SG1 is connected with SG2 tunnel tube coupling again and be stitched together.And then as stated above that remaining tunnel tube coupling is all in place, and all tunnel tube couplings series connection are stitched together with the method for bolt or welding; After the series connection splicing was good, the mass 4 with water in tunnel tube coupling SG1, SG2, the SG3------SGn or outer system removed again, removes the sealing at all tube coupling two ends, tunnel at last again, and just can make it has become the tunnel of a perforation.
