The invention provides a water drainage device and a water drainage method thereof for construction foundation engineering. The device comprises a first water collection pit for accommodating first accumulated water, a second water collection pit for accommodating second accumulated water, an enclosed cover, a water suction pipe and a water drainage pump, wherein the enclosed cover is mounted in the first water collection pit and is provided with an enclosed side positioned above a first liquid level of the first accumulated water and an opening side positioned below the first liquid level, and a water suction hole is formed in the enclosed side; the water suction pipe is provided with a water inlet end positioned under a second liquid level of the second accumulated water and a water outlet end communicating with the water suction hole; the water drainage pump is arranged under the first liquid level and communicates with a water drainage pipe, after the water is drained by the water drainage pump, a negative pressure cavity is formed between the first liquid level and the inner wall of the enclosed side, and the negative pressure cavity communicates with the water suction hole. According to the water drainage device disclosed by the invention, the problem that when accumulated water in many parts of foundation pits need to be pumped and drained, the water pumping and drainage efficiency is low by adopting a conventional pumping and drainage way is solved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a drainage device and a drainage method for building foundation engineering. Background technique [0002] In the foundation construction of modern buildings, more and more constructions such as foundation pits and caps are involved. Pile foundations are often used as foundations of buildings today, but in rainy areas in the south, there is a lot of precipitation, and water accumulation in large underground foundation pits will seriously affect the construction progress and safety of foundation pits. Most of the caps in the foundation pit are arranged in a scattered manner. When draining and pumping water, it is necessary to pump water one by one. Each cap needs to be equipped with a drainage pump. The drainage efficiency is low, which delays the construction period and requires more water pumps. , It is also inconvenient to connect to the electricity. The traditi...
