Automated drainage system for buildings and construction method

Abstract

The invention relates to an automated drainage system for buildings and a construction method and relates to the field of building drainage. By means of the automated drainage system for the buildings, the problem that once electricity is cut off, an existing drainage system cannot work is solved. The automated drainage system for the buildings comprises a drainage ditch arranged on the edge sideposition of the bottom wall of a foundation pit, a water collecting well arranged in the foundation pit and communicating with the drainage ditch, a submerged pump arranged in the water collecting well, a drainage pipe arranged between the submerged pump and the outer side of the foundation pit and an automatic drainage part arranged on the submerged pump. A siphoning drainage well is arranged onthe outer side of the foundation pit. A siphon is arranged between the syphoning drainage well and the water collecting well. A water suction pipe is connected to the end, extending into the water collecting well, of the siphon. A water output pipe is connected to the end, extending into the siphoning drainage well, of the siphon. The water output end of the water output pipe is lower than the water input end of the water suction pipe. A water-discharging pipe is arranged at the bottom end of the siphoning drainage well. According to the automated drainage system for the buildings, under the circumstance of power cut, drainage work can still be conducted in the foundation pit; and in the meantime, time is won for electricity repair, and normal conducting of construction is guaranteed.

Description

technical field [0001] The present application relates to the field of building drainage, in particular to a building automatic drainage system and a construction method. Background technique [0002] With the development of the construction industry and science and technology, high-rise buildings are gradually becoming popular. During the construction of high-rise buildings, the construction of deep foundation pits in the basement is required; during the construction of the foundation pits, the drainage of the foundation pits runs through the entire underground construction. The whole process directly affects the quality and safety of foundation construction. [0003] The existing Chinese patent with the publication number CN106120831B discloses a building automation drainage system and construction method, including an open water collection system and a drainage system, the open water collection system includes a drainage ditch and a water collection well, and the drainage...

Problems solved by technology

[0004] However, the above-mentioned patent has the following defects: because the work of the float switch and the submersible pump requires power support, once a power failure occurs, the entire drainage system cannot work, so that the paralyzed drainage system cannot continue to work before the power maintenance is completed. , especially in rainy days, it is easy to cause the problem of water accumulation in the foundation pit
