Branch pipe type under-construction deep pit building anti-ponding system

Abstract

The invention belongs to the technical field of building construction and particularly relates to a branch pipe type under-construction deep pit building anti-ponding system. The system comprises pipeburying pits which are disposed around the edge of a building deep pit; water collecting pipes are buried in the pipe burying pits; a water guiding pipe is connected to the water collecting pipe on at least one side, and the other ends of the water guiding pipes extend into a deep well pipe; a deep well pump is disposed in the deep well pipe; a water outlet of the deep well pump is connected witha draining pipe; the other end of the draining pipe extends into a water storing pool; water seepage pipes are connected to the pipe bodies of the water collecting pipes; water seepage holes which are distributed at intervals in the pipe length direction of the water seepage pipes are formed in the water seepage pipes; and water are collected in the water collecting pipes through the water seepage pipes, flow into the deep well pipe through the water guiding pipes and are pumped into the water storing pool under the action of the deep well pump. By means of the anti-ponding system, the effectthat no water is seeped into the portion above the bottom plane of a building foundation so that the dry state can be kept is guaranteed, the defect that in the prior art, ponding occurs into an under-construction building without an anti-ponding system is overcome, and the purpose that ponding water is rapidly and effectively pumped out in time is achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a branch-type anti-water system for deep pit buildings under construction. Background technique [0002] In recent years, with the rapid development of cities in our country, deep pit buildings abound. However, the southern part of my country is rich in water systems, with high groundwater levels and high soil water content. For many high-rise buildings, deep pits need to be excavated during the construction process. If the soil is not compacted in time, a large amount of water will be generated in the backfill pit, and sometimes even the backfill soil in the water accumulation area will become a puddle of mud, resulting in the embarrassment that it cannot be compacted. Normal construction can only be done after drainage. On the one hand, it will affect the progress of the construction project, delay the construction period, and bring disadvantages to the...
