Basement construction dewatering and drainage device and construction method thereof

Abstract

The invention provides a basement construction dewatering and drainage device which mainly comprises a drainage pipe, a ventilation pipe, full-bore ball valves and a fixing pipe. The upper end of the drainage pipe and the upper end of the ventilation pipe are provided with the full-bore ball valves respectively. The drainage pipe and the ventilation pipe are installed on the fixing pipe. The fixing pipe comprises a steel pipe and a corrugated pipe. The fixing plate is provided with a sealing steel plate. The invention further provides a construction method of the dewatering and drainage device. The construction method comprises the steps that 1, a sump is arranged and filled with broken stone, and the corrugated pipe is buried in the sump; 2, the upper portion structure of the dewatering and drainage device is embedded into the upper end of the corrugated pipe; 3, a hose is installed, and the full-bore ball valves are opened for dewatering and drainage; 4, the full-bore ball valves are closed, and sedimentation post-cast strip pouring is carried out. The basement construction dewatering and drainage device has the beneficial effects that various problems produced when a basement bottom plate is affected by water pressure are effectively solved, construction requirements are met, the portion, at the position of the dewatering and drainage device, of the bottom plate can be poured together with a post-cast strip during closing, and the basement construction dewatering and drainage device is simple in structure, convenient to construct, economical, environmentally friendly, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of foundation pit drainage, in particular to a basement construction drainage device and a construction method thereof. Background technique [0002] With the rapid development of urban construction, more and more underground space has been utilized, especially with the increase of high-rise and super high-rise buildings, the application of multi-storey basements is becoming more and more frequent. However, as the depth of the basement deepens, the floor of the basement is more affected by the water pressure in the soil layer. When the floor is closed, the abundant groundwater in the soil layer may form a greater pressure on the local area of ​​the floor, causing the floor to arch and seep. Water leakage, or even overall floating, is extremely detrimental to ensuring the construction quality of the basement, and the role of basement drainage in construction is becoming more and more significant.
