Embodiment Construction

[0020] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] The present invention is composed of water control valve 100, Y-shaped pipeline filter 200, adjustable drain valve 300 and other components to form an automatic pressure regulating drain device, and the direction of underground water flow is as follows: figure 1 As shown, the left side of the device is connected to the groundwater seepage pipe behind the lining, and the right side is connected to the tunnel lateral drainage pipe. The automatic pressure regulating and draining device needs to be pre-embedded during the tunnel construction process to complete the pressure regulating and draining function of groundwater. The device needs to be designed according to the size and function of the inner space of the tunnel lining. Different specifications and models can be formulated according to different engineering profile...

Abstract

The invention discloses an automatic pressure regulation type sluicing control device for a tunnel in a high-pressure water-abundant area. The device is arranged at the bottom of each cable groove of an operation tunnel in a wall footing limited discharge area of the tunnel in the high-pressure water-abundant area. A water inlet of the device is connected a lining back underground water seepage pipeline, and a water outlet of the device is connected with a tunnel transverse water discharge pipe. A water control valve 100, a Y-type pipeline filter 200 and an adjustable sluice valve 300 are sequentially arranged between the water inlet and the water outlet to form an automatic pressure regulation type slicing control mechanism. The automatic pressure regulation type sluicing control device has advantages that lining external drainage and an internal tunnel drainage system can be flexibly combined, a sluicing threshold is set, and automatic water drainage is realized along with water quantity changes, so that water pressure applied to linings is adjusted; further, silt in underground water can be filtered while filtered substances can be changed at any time to effectively reduce sluice valve damage probability, the sluice valve can also be replaced at any time, convenience in use is achieved, and tunnel lining structural safety is guaranteed.

Description

[0001] Technical field: [0002] The invention belongs to tunnels and underground engineering settings, in particular to an automatic pressure-regulating and water-releasing control drainage system for tunnels in high-pressure water-rich areas. [0003] Background technique: [0004] At present, the principle of limited discharge is generally followed in the design of mountain tunnels in high-pressure water-rich areas at home and abroad. A typical way is to install control valves in the tunnel's waterproof and drainage system. When the water pressure reaches a certain value, the valve opens to drain water. , When the water pressure is lower than a certain value, the valve is closed. This kind of control drainage system has been used in Guangzhou subway tunnels, but due to the frequent opening and closing, the valves are easily damaged, and the water contains a lot of mud and sand, which often makes the valves blocked and invalid. Contents of the invention [0005] In view of...
