High-strength reinforced concrete assembly type seepage and drainage pipeline structure of expressway tunnel

Abstract

The invention discloses an expressway tunnel high-strength reinforced concrete assembly type seepage and drainage pipeline structure and relates to the technical field of expressway tunnel drainage. The expressway tunnel high-strength reinforced concrete assembly type seepage and drainage pipeline structure comprises a drainage channel, wherein a water leakage cover plate is movably installed at the top of the drainage channel, a cleaning end is fixedly installed at a left end of the drainage channel, a movable mechanism is arranged on the inner side of the drainage channel, a buffering mechanism is arranged on the inner side of the drainage channel, and seepage holes are formed in an outer surface of the drainage channel; and the movable mechanism comprises a high-pressure nozzle, a rotating plate and an elastic strip. According to the highway tunnel high-strength reinforced concrete assembly type seepage and drainage pipeline structure, the movable mechanism and the buffering mechanism are arranged, impact force caused to the drainage channel in the high-speed running process of a vehicle is weakened, sundries in the drainage channel are rapidly discharged, and the situation that the sundries are attached to the inner wall of the drainage channel, and the drainage performance of the drainage channel is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of expressway tunnel drainage, in particular to a high-strength reinforced concrete assembled seepage drainage pipeline structure for expressway tunnels. Background technique [0002] The number of expressway construction projects is increasing day by day, and tunnel engineering plays an important role in expressway construction. The engineering geology and hydrogeological conditions of the expressway tunnel location will have a direct impact on the construction process of the tunnel, and will also affect the construction quality of the tunnel and the safety of the tunnel. The operation has a great impact. In the construction and operation of the tunnel, the setting of the drainage system is very critical. During the operation of some tunnels, due to the high groundwater level, groundwater rushes from below the road surface to the inside of the road surface, or even above the road surface, causing water dama...

Problems solved by technology

[0003] And when the drainage pipe is in use, a lot of dust and debris will be brought into the drainage pipe through the drainage hole during the vehicle driving project. When using the preset nozzle for flushing, the dust and debris cannot be quickly detached from the inner wall of the drainage pipe and remain in the drainage pipe. Debris on the inside of the pipe affects the drainage performance of the drainage pipe
