Dewatering and drainage system with detachable water collection tanks and dewatering and drainage method of dewatering and drainage system

Abstract

The invention discloses a dewatering and drainage system with detachable water collection tanks and a dewatering and drainage method of the dewatering and drainage system and relates to the field of municipal deep foundation pit dewatering and drainage construction. The dewatering and drainage system comprises a dewatering well, a water collection tank set, drainage pipes and a dewatering pipe. The water collection tank set comprises a one-way water collection tank, a two-way direct-connection water collection tank, a two-way corner water collection tank, a three-way water collection tank and a four-way water collection tank. Each of the one-way water collection tank, the two-way direct-connection water collection tank, the two-way corner water collection tank, the three-way water collection tank and the four-way water collection tank comprises a bottom plate and a cylindrical plate fixed to the bottom plate, each bottom plate and the corresponding cylindrical plate form a box-shaped structure without a cover. The cylindrical plates are all provided with holes and connector pipes arranged on the holes. The drainage pipes are detachably connected to the connector pipe. One end of the dewatering pipe is located in any one of the water collection tank set, the other end is located in the dewatering well, and the end portion of the end, located in the dewatering well, of the dewatering pipe is provided with a water pump. According to the dewatering and drainage system and method, the water collection tanks which can be detached and used repeatedly can be arranged flexibly according to the terrain environment, and the system is low in cost and high in adaptive capacity.

Description

technical field [0001] The invention relates to the field of municipal deep foundation pit drainage construction, in particular to a drainage system provided with a detachable water collection box and a drainage method thereof. Background technique [0002] At present, more and more large-scale underground structures are constructed using deep foundation pit drainage. The characteristics of municipal engineering are short construction period, tight time, small site and fast process change. The drainage system is a key project in the municipal deep foundation pit excavation project, and the water collection tank is the key link in the drainage system. Whether the setting is reasonable or not is related to the success or failure of the drainage system. At present, the water collection tank (pool) in the municipal precipitation system is generally formed by brick masonry, and its characteristic is that the water collection tank (pool) is for one-time use and cannot be moved an...
