Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, in particular to a press-in self-advancing gas expansion double filter tube horizontal drainage well device. Background Art

[0002] Groundwater has an adverse effect on underground engineering. In many construction projects, especially tunnel engineering, a small amount of water gushing usually has little effect on tunnel construction, but a large amount of tunnel gushing and water bursting will have a serious impact on tunnel construction, and even bury construction personnel and equipment. Therefore, in the construction of tunnel engineering, it is often necessary to discharge water and relieve pressure on the face in real time during excavation. If there is a semi-rock stratum in front of the tunnel face, excavation will cause high-pressure water bursting, and then due to penetration damage, flowing soil and sand will be produced, until landslides and mud bursting occur, which will cause the safety of construction personnel and a large amount of construction equipment. In addition, it will seriously affect the construction progress. Therefore, when mud bursts and water gushing occur in semi-rock tunnels, horizontal water discharge is required.

[0003] However, if the traditional drilling and pipe laying method is adopted, it may cause sudden surge. The same problem will occur if the drainage pipe is directly driven into the drainage pipe.

[0004] Therefore, there is an urgent need for a device that can improve the high-pressure water inrush caused by tunnel excavation, and then prevent soil flow, sand flow, and even landslides and mud gushing caused by penetration damage. Summary of the invention

[0005] The purpose of the present invention is to provide a press-in self-advancing gas-expanding double filter tube horizontal drainage well device and its working method in order to overcome the defects of the above-mentioned prior art. By arranging a double filter tube, it is possible to effectively prevent the mud in the water from blocking the openings on the side walls of the filter tubes. An inflatable water-stopping airbag is arranged, which can partially block the openings of the horizontal drainage well after pressurization, thereby avoiding sudden surges. The main body of the gas-expanding double filter tube horizontal drainage well of the present invention can be repeatedly used. After the main body of the gas-expanding double filter tube horizontal drainage well is pushed into a semi-diagenetic formation, other gas-expanding double filter tube horizontal drainage well main bodies can be continuously pushed into the surrounding semi-diagenetic formations after the fixed pressurizing component (6) is removed.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0013] Furthermore, the valve can be a gate valve, which includes a gate seat and a gate plate connected to the gate seat; the gate valve is sealed by the contact between the gate plate and the gate seat, and the airbag pressurization tube is arranged below the gate plate. After removing the fixed pressurization component, when the gate plate is closed (in a low position), the gate plate and the inner wall of the gate seat press the airbag pressurization tube on both sides, and the gas is cut off in the inflatable water-stop airbag, and it cannot be discharged through the airbag pressurization tube. When the gate plate is opened (in a high position), the gate plate and the inner wall of the gate seat no longer press the airbag pressurization tube, and the gas is no longer cut off in the inflatable water-stop airbag, and it can be discharged through the airbag pressurization tube. Before removing the fixed pressurization component, the gate plate is opened (in a high position) to inflate the inflatable water-stop airbag.
