Technical Field
The present utility model relates to a lock arranged on the downstream side of a water blocking line, and more particularly to a lock wall rear drainage system.
Background
At present, a lock wall of a ship lock is composed of a retaining wall platform and a retaining wall vertically arranged on the retaining wall platform, and is arranged on the bank of a river along the water flow direction of the river. The water seepage pressure behind the lock is one of the main loads of the lock structure, and the underground water level is mainly influenced by factors such as the water level on the upper and the lower sides of the lock and the surface rain water seepage, so that the water seepage pressure of the underground water behind the lock can be effectively reduced by arranging a drainage system behind the lock, and the stability of the lock structure is ensured. The conventional sluice wall rear drainage system mostly adopts the forms of a perforated drainage pipe, a broken stone drainage blind ditch and the like; the perforated drain pipe is usually made of concrete, plastic, cast iron and the like, and one or more seepage channels are arranged on the retaining wall platform along the longitudinal direction (parallel to the retaining wall direction) according to the water head height. The above-described drainage system has the following drawbacks: 1. the perforated drain pipe has high installation and positioning requirements, cannot adapt to foundation settlement and is easy to damage; 2. the broken stone drainage blind ditch is simple in construction, low in price and small in drainage area, and the flexible structure can adapt to foundation deformation, so that the broken stone drainage blind ditch is easy to block; 3. the simple longitudinal seepage passage has small contact area with the filled soil, low drainage efficiency, existence of drainage blind areas, poor drainage effect and threat to the safety of the sluice wall structure. Therefore, the conventional drainage system behind the lock wall has certain defects in terms of construction cost, structural reliability and drainage capacity.
Disclosure of Invention
