Background
The blind pipe is a drainage pipeline in the tunnel, and the tunnel is positioned in a mountain or underground in a city, so that water always permeates downwards in the mountain at the top of the tunnel, and the underground water such as rainwater also permeates downwards in the city. When a lining of the tunnel, which is in contact with rock strata around the tunnel, is broken, water flow accumulated at the top of the tunnel enters the lining, and the blind pipe plays a role in draining water. The blind pipe is usually for the material that permeates water makes or set up by hollow out construction on the blind pipe surface, be that the blind pipe optional position can both absorb water and with water downstream to prevent that ponding from gathering at the tunnel top, finally lead to tunnel top ponding too much and the problem of leaking. The water flow velocity in the blind pipe is limited, and a lot of impurities are necessarily carried along with the seepage of water in the stratum. When water flows into the blind pipe, calcium or other elements in the water are condensed due to low flow velocity, the driving force for granular impurities is small, the condensed crystals or the granular impurities which cannot be taken away are easy to cause blockage of the blind pipe, and therefore the hydrophobic capacity of the blind pipe is reduced. For example, the patent of invention with application number 201810494444.3 and named as a tunnel lining structure three-dimensional waterproof and drainage system is provided with a complex three-dimensional drainage system for preventing white crystalline objects from appearing on annular blind pipes and longitudinal blind pipes, although the three-dimensional drainage structure can play a certain anti-crystallization effect and prolong the crystallization forming speed, the whole structure is complex, and the construction workload is increased.

Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following.
As shown in figures 1-2, the siphon rapid drainage crystallization-prevention blind pipe and the installation method thereof are characterized in that the blind pipe is hollow, and a drainage groove 1 is arranged on the surface of the blind pipe. The blind pipe of fretwork form can follow the arbitrary department of lateral wall and absorb the water of infiltration, and water drainage tank 1 has then formed the direct passageway that flows downwards of messenger's water, and when water permeates to fretwork hole 2, belongs to horizontal infiltration or downward infiltration to one side basically, and the shape of fretwork hole 2 is crooked irregularly, can restrict the speed of rivers, and the reduction of water velocity produces the crystallization more easily, also causes the jam of granular impurity more easily. Therefore when water under the infiltration gets into water drainage tank 1, can follow water drainage tank 1 and directly flow downwards, under the state that rivers continue to flow downwards, can produce the siphon effect in water drainage tank 1, make the water of the broken department of a lining more flow to water drainage tank 1 for the speed of walking away of rivers, flow speed when rivers rises, and the material in the aquatic is difficult to condense and forms the crystallization, and granular material is taken away more easily. Thereby achieving the purposes of reducing the crystallization efficiency and prolonging the practical service life of the blind pipe.
Preferably, the drainage channel 1 is arranged along the axial direction of the blind pipe, and two ends of the drainage channel 1 are communicated with two end faces of the blind pipe. A blind pipe can be provided with a plurality of drainage channels 1, so that the drainage effect is improved.
Preferably, the width of the drainage channel 1 is larger than the diameter of the hollow hole 2 on the blind pipe.
Preferably, the depth of the drainage channel 1 is greater than the diameter of the hollow hole 2 on the blind pipe.
Preferably, the cross section of the drainage channel 1 is rectangular.
The installation method of the siphon rapid drainage anti-crystallization blind pipe comprises the following steps:
s1, spraying slurry to the inner wall of the tunnel to form a lining in the tunnel;
s2, after a lining is formed, arranging the blind pipes from the vault of the tunnel to two sides, and fixing the blind pipes on the inner wall of the lining; and make a water drainage tank 1 paste on a lining inner wall, appear broken when one lining, hydroenergy can directly get into water drainage tank 1 in, reach the effect of quick drainage.
S3, fixing a waterproof plate, wherein the blind pipe is positioned between a lining and the waterproof plate;
and S4, spraying again to form a second lining on the inner wall of the waterproof board.
The blind pipe is located between waterproof board and the lining, and the waterproof board outside guniting forms two linings, therefore the blind pipe itself is located inclosed space, receives mountain ridge deformation or other reasons to destroy the back as a lining, and rivers in the mountain ridge get into a lining, then contact with the blind pipe and discharge the infiltration water to the bottom of tunnel both sides by the blind pipe, prevent tunnel top ponding. When the blind pipe drains, the permeate water is mainly discharged through the water discharge groove 1, and the water discharge groove 1 provides a direct downward flow passage, so that the permeate water can flow rapidly. Just because the blind pipe is in the enclosed space, the flow of water flow will cause the pressure above the water drainage channel 1 to decrease, creating a siphon effect, and promoting other permeate water entering a liner to flow towards the water drainage channel 1, thus being quickly discharged from the water drainage channel 1. Under the condition of large water flow velocity, substances in water are not easy to condense, and the possibility of crystallization is greatly reduced. Meanwhile, the flow velocity of water flow is high, granular impurities can be driven to directly flow away, and blockage in a blind pipe cannot be caused. For impurities which cannot enter the drainage channel 1, the inside of the blind pipe cannot be blocked naturally.
