Description
Technical field
The utility model belongs to Tunnel Engineering technical field, in particular to a kind of river for under-traverse tunnel construction area is led
Flow device.
Background technique
When the Tunnel Engineering such as subway, municipal piping lane wear river under and construct, need to carry out cofferdam water conservancy diversion to river, with drop
Low soil moisture content reduces sedimentation, provides a good environment for lower part constructing tunnel.Construction period tunnel is also reduced simultaneously
Load above road.This orderly drainage pattern reduces river compared with unordered draining before and produces to the construction of under-traverse tunnel
Raw influence.
Common cofferdam method of river diversion predominantly stops, excavates diversion channel, aqueduct water conservancy diversion, is laid with the modes such as waterproof blanket.
The construction method for taking cutout is the water cutting by setting cofferdam by upper river, so that the cutout that flows down, from
And reduce lower milliosmolarity.But when upstream water is larger, this method not only will not play corresponding effect instead and will increase construction wind
Danger.
Excavating diversion channel is then to excavate diversion channel in the one or both sides in river, and required construction working face is larger, is leading
It will drink water again after the bottom Liu Qu laying waterproof blanket and introduce diversion channel, although which reduces water percolating capacity, but this method does not reduce
The load that tunnel top is born, and be not suitable in city narrow on construction ground.
Using the method for laying waterproof blanket, its main method is that river shuts off first, and left and right half range builds U-shaped cofferdam, clearly
Water supply and mud in riverbed are managed, waterproof blanket is then re-layed, restores water flowing after the completion of waterproof blanket to be laid.The engineering of this method construction
Measure larger, long construction period.And there is certain disturbance to the upper soil horizon in tunnel.
As it can be seen that construction workload needed for the river method of river diversion in existing constructing tunnel area is larger, long construction period, to existing
There is unfavorable construction surface caused by riverbed larger, surrounding enviroment are had an impact, is not suitable for the narrow region in construction site.
Utility model content
The purpose of this utility model is to provide a kind of river guiding devices for under-traverse tunnel construction area, on solving
State problem.
To achieve the above object, the utility model uses following technical scheme:
A kind of river guiding device for under-traverse tunnel construction area, including wavy metal culvert pipe, cofferdam, fashioned iron and steel
Cord；Two cofferdams are arranged at intervals in river, and cofferdam is perpendicular to channel flow direction；It is arranged between two cofferdams
There are several wavy metal culvert pipe, wavy metal culvert pipe does not connect bottom of river channel；Several fashioned iron across be arranged on river, wavy metal
Culvert pipe is located at the lower section of fashioned iron, is connected between fashioned iron and wavy metal culvert pipe by wirerope；Cofferdam is for shutting off.
Further, several fashioned iron are disposed in parallel relation to one another, and there are gap, several fashioned iron upper surface fixed settings between fashioned iron
There are several seamless steel pipes, the number of seamless steel pipe is identical as wavy metal culvert pipe.
Further, several hanging rings are arranged on wavy metal culvert pipe, an end cap of wirerope is another on seamless steel pipe
End is fixedly connected with hanging ring；Wire line shoe is provided on wirerope.
Further, fashioned iron is H profile steel.
Further, river edge is provided with concrete belt along river flow direction, and fashioned iron is placed in bar shaped concrete belt
On.
Compared with prior art, the utility model has following technical effect:
Guiding device provided by the utility model realizes down the unloading of the water ballast(ing) on tunneling hole top, reduces simultaneously
The influence in lower infiltration tunneling hole under.The orderly draining that the device is formed does not influence the normal excretory function in river, to peripheral ring
The influence in border is smaller.
Guiding device provided by the utility model, construction is simple, the high recycling rate of selected materials, wavy metal are contained
Pipe, wirerope, seamless steel pipe and fashioned iron can utilize again.
Wire line shoe is set in the middle part of wirerope, to realize elevating control that wirerope obtains wavy metal culvert pipe；
Fashioned iron is placed on bar shaped concrete belt, avoids being directly placed at caused sedimentation on the soil body.

Specific embodiment
Below in conjunction with attached drawing, the present invention will be further described:
A kind of river guiding device for under-traverse tunnel construction area referring to FIG. 1 to FIG. 4, including wavy metal culvert pipe
1, cofferdam 9, fashioned iron 4 and wirerope 3；Two cofferdams 9 are arranged at intervals in river, and cofferdam 9 is perpendicular to channel flow
Direction；Several wavy metal culvert pipe 1 are provided between two cofferdams 9, wavy metal culvert pipe 1 does not connect bottom of river channel；If dry type
For steel 4 across being arranged on river, wavy metal culvert pipe 1 is located at the lower section of fashioned iron 4, passes through between fashioned iron 4 and wavy metal culvert pipe 1
