Problems of drainage in the shotcrete construction stage of the water-rich tunnel are solved, engineering quality is improved, safety risks are reduced, and economic benefit is obvious.
Description
Technical field
The present invention relates to technical field of tunnel construction, be specifically related to a kind of waterproof and water drainage system just propping up the construction stage for tunnel.
Background technology
In the current tunnel water handling stage, mainly between barrel composite lining, adopt specific waterproof and drain measure, often have ignored waterproof and drain measure when just propping up construction.And when just propping up construction, a large amount of underground water or too high hydraulic pressure can cause tunnel gushing water, prominent mud, even there is landslide phenomenon.
In engineering construction, excavation face is positioned at below groundwater table, inevasiblely underground water will be touched, excavation causes Groundwater equilibrium pressure to destroy, underground water is caused to start to excavation cavity place seepage, whole engineering is propped up in work progress be just in " weather of the continues patter of raindrops " always, this makes difficulty of construction increase, efficiency of construction reduces, dangerous and the destabilizing factor of engineering structures also can increase, construction technology will become numerous and diverse, and the uncertainty of whole engineering and risk can be following.
Summary of the invention
The present invention is the water damage problem that solution rich water tunnel just props up in construction, devises a kind of waterproof and water drainage system just propping up the construction stage for tunnel.
The present invention is achieved through the following technical solutions:
A kind of waterproof and water drainage system just propping up the construction stage for tunnel, it includes top board waterproof and water drainage system and stalk waterproof and water drainage system, described top board waterproof and water drainage system is primarily of the top board aqueduct composition vertically squeezing into the tunnel top soil body, described stalk waterproof and water drainage system is primarily of tilting upward the stalk aqueduct composition squeezing into tunnel soil at both sides, described top board aqueduct and the part that stalk aqueduct is squeezing into the soil body are provided with extravasating hole, are provided with sump below the mouth of pipe of described top board aqueduct and stalk aqueduct.
More preferably, described top board waterproof and water drainage system is arranged at intervals with the top board aqueduct vertically squeezing into the top soil body, described top board aqueduct is arranged respectively in the arranged on left and right sides of tunnel top, be connected with between the top board aqueduct of arranged on left and right sides and be obliquely installed and part gos deep into the draining blind pipe of the soil body, described draining blind pipe has the inlet opening set in a row in the part going deep into soil.
More preferably, described stalk waterproof and water drainage system is arranged at intervals with the stalk aqueduct upwards squeezing into tunnel soil at both sides with 30 degree of overturning angles.
More preferably, described top board aqueduct is provided with loaded filter with the position that stalk aqueduct is contacting with the soil body.
More preferably, described top board aqueduct or stalk aqueduct also can be used as Grouting Pipe and carry out slip casting from inside to outside.
Beneficial effect of the present invention is embodied in three aspects: one, improve workmanship: by intercepting in the just ejectment of construction stage to underground water, make waterproof measure effect during lining cutting obtain qualitative leap, later stage leakproof phenomenon occurs; Two, remarkable in economical benefits: without the need to introducing special equipment, without the need to introducing special operation workers, aqueduct simultaneously double Grouting Pipe of doing uses the unlikely waste causing material; Three, security risk is low: good slip casting effect can guarantee the firm of soil layer, in addition sectional pressure relief, not easily occurs the generation of gushing water, water burst phenomenon in tunnel, and dry clean and tidy ground also reduces the dangerous generation such as electric shock, personnel's actual bodily harm.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of top board waterproof and water drainage system.
In figure, 1 soil body, 2 top board aqueducts, 3 draining blind pipes, 4 loaded filters, 5 stalk aqueducts, 6 sumps, 7 extravasating hole, 8 inlet openings.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.As described in Figure 1, it includes top board waterproof and water drainage system and stalk waterproof and water drainage system, described top board waterproof and water drainage system forms primarily of the top board aqueduct 2 vertically squeezing into the tunnel top soil body 1, described stalk waterproof and water drainage system forms primarily of tilting upward the stalk aqueduct 5 squeezing into tunnel soil at both sides, described top board aqueduct and stalk aqueduct are provided with extravasating hole 7 in the part squeezing into the soil body, are provided with sump 6 below the mouth of pipe of described top board aqueduct and stalk aqueduct.Underground water in the soil body can be entered by the extravasating hole on top board aqueduct and stalk aqueduct manages interior and is discharged in sump.
Further, as shown in Figure 2, described top board waterproof and water drainage system is arranged at intervals with the top board aqueduct 2 vertically squeezing into the top soil body, described top board aqueduct is arranged respectively in the arranged on left and right sides of tunnel top, be connected with between the top board aqueduct of arranged on left and right sides and be obliquely installed and part gos deep into the draining blind pipe 3 of the soil body, described draining blind pipe has the inlet opening 8 set in a row in the part going deep into soil, underground water in the soil body enters in pipe by the inlet opening on draining blind pipe, and is discharged in sump by the top board aqueduct of side.
Further, described stalk waterproof and water drainage system is arranged at intervals with the stalk aqueduct upwards squeezing into tunnel soil at both sides with 30 degree of overturning angles.
Further, described top board aqueduct is provided with loaded filter 4 with stalk aqueduct at the position contacted with the soil body.
Further, described extravasating hole is quincunx distribution on top board aqueduct or stalk aqueduct.
Further, described top board aqueduct or stalk aqueduct are wound with a circle non-woven fabrics in the part squeezing into the soil body.
Further, described top board aqueduct or stalk aqueduct adopt seamless steel pipe.
Further, described draining blind pipe adopts PVC material.
Further, described draining blind pipe is provided with 2-3 in the part going deep into soil and arranges inlet opening.
