Description

Highway tunnel water-proof drainage system overhauls facility Technical Field The utility model relates to the technical field of tunnel overhaul, in particular to an overhaul facility of a highway tunnel water-proof and drainage system. Background The drainage structure is an important measure for guaranteeing the operation of a highway tunnel, substances carried by underground water flow can be deposited in a drain pipe and a drainage ditch, the highway tunnel is an underground hidden project, the quality control of the construction of the tunnel drainage project at the present stage is very difficult, the drainage ditch pipe is often subjected to construction quality problems such as discontinuous section, uneven ditch wall, construction waste blockage and the like, the blockage of a drainage system is further aggravated, a series of tunnel safety hazards are further caused, for example, the drain pipe is blocked to cause ponding in the tunnel, infiltrates into an illumination ventilation system and even erodes a tunnel concrete structure gap, the structural stability is weakened, therefore, the tunnel drainage system is required to be checked, maintained and dredged periodically, the reliability of the tunnel drainage system is guaranteed, and the safety and toughness of the tunnel operation are improved. Among the current tunnel structure, different waterproof and drainage structures have different maintenance modes, the drainage side ditch sets up in the road both sides, can directly open the apron and overhaul, vertical and hoop drain pipe is then through setting up the import in tunnel lateral wall department, overhaul by small-size maintenance robot, the center escape canal that is located the road surface below then sets up by the road surface downwards and examines and repair the well, overhaul through the manhole, but conventional manhole interval sets up on the traffic lane, during the detection, need manage the traffic, influence the tunnel and lead to the fact traffic safety hidden danger easily, and the entry of examining and repair the well mostly sets up in the road middle part, this setting position leads to its unable increase space, the operation space limitation in the well is unfavorable for intelligent check out equipment or detects the operation of car, be unfavorable for subsequent drainage pipeline mediation more.
