Abstract

The invention discloses a highway tunnel drainage disease treatment construction process, and belongs to the field of tunnel drainage treatment. Comprising snakelike robot dredging and a replaceable drainage pipe inner pipe. According to the highway tunnel drainage disease treatment construction technology, solid clogging of a drainage pipe is treated through a snake-shaped robot, then disintegrating slag is cleaned through high-pressure water, and finally an inner pipe of the drainage pipe is replaced. The device is favorable for comprehensively removing the clogging of the highway tunnel, avoids the damage of the highway tunnel, and guarantees the driving safety of vehicles in the tunnel.

Description

Technical Field

[0001] The invention relates to the field of tunnel drainage management. Background Art

[0002] According to statistics, nearly 1 / 3 of my country's railway, highway and subway tunnels have water leakage problems, of which 70% of tunnel leakage is caused by drainage pipe blockage. Once the drainage pipe is blocked and fails, it is easy to cause the water pressure behind the lining to increase, the support structure to deteriorate, crack, become unstable or even peel off, seriously affecting the life of the tunnel and operational safety. Therefore, a construction process for the treatment of highway tunnel drainage problems is proposed. Summary of the invention

[0003] The purpose of the present invention is to provide a construction process for treating drainage defects in highway tunnels, so as to solve the problem that the above-mentioned background technology is prone to cause safety hazards and endanger the safety of vehicles driving in tunnels. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A construction process for treating drainage defects in highway tunnels, comprising the following steps:

[0004] Step 1: Groove dredging construction:

[0005] During tunnel construction, double-layer drainage pipes with replaceable inner pipes are buried;

[0006] Pipeline inspection: Use visual detection equipment to inspect horizontal and vertical drainage pipes and circular or vertical blind pipes to determine blockages and blockage conditions.

[0007] Blockage crushing: According to different blockages, the front end of the tunnel serpentine crushing robot is equipped with different crushing reamer heads to crush crystals, concrete slurry and other blockages;

[0008] Pipe cleaning: Use high-pressure water dredging equipment to clean and dredge the attachments on the surface of the pipe. Use visual detection equipment to detect the horizontal and vertical drainage pipes and the circular or vertical blind pipes. If the blockage is not completely removed, repeat step (3);

[0009] Dredging and desilting: The high-pressure jet water pump group module of the tunnel drainage system maintenance comprehensive equipment is equipped with a high-pressure water jet to flush the crushed crystals into the side ditch or the central ditch. The filter device pre-installed at the pipe mouth will filter out the crystals for subsequent treatment, and the silt crystals and other debris will be bagged and taken out;

[0010] Replace the inner pipe of the drain pipe: Use mechanical equipment to extract the inner pipe of the drain pipe and replace it with a new one.

[0011] The robot used is a snake-like robot with a maximum curvature of 2 × 45° in DN70 and a maximum curvature of 90° in DN100.

[0012] The drainage pipe needs to be a double-layered replaceable inner pipe during construction.

[0013] Compared with the prior art, the invention has the following beneficial effects: the highway tunnel drainage disease treatment construction process first uses a snake-like robot to deal with solid blockage in the drainage pipe, then uses high-pressure water to clean up the debris, and finally replaces the inner pipe of the drainage pipe. It is conducive to comprehensively clearing blockage in highway tunnels, avoiding diseases in highway tunnels, and ensuring the safety of vehicles driving in tunnels.
