Problems solved by technology

At the same time, the construction of water collection and drainage during the foundation construction stage is becoming more and more common. At present, the precipitation in the construction stage mostly adopts open ditches and open drains, which has limitations in construction. The sealing method of the later stage has caused the quality of the later waterproof, cushion, and concrete construction to be unqualified. Therefore, a dewatering construction method is needed now, which can effectively discharge the accumulated water in the foundation pit and seal the water collection well when it needs to be blocked. block up

Embodiment Construction

[0017] In order to further understand the method for installing and blocking the dewatering device in the foundation pit of the present invention, the technical solution of the present invention and its beneficial effects will be described in detail below through examples and accompanying drawings.

[0018] The method for the installation and plugging of the dewatering device in the processing foundation pit of the present invention comprises the following steps:

[0019] Such as figure 1 As shown, make aquifer 5;

[0020] The aquifer 5 is made up of crushed stones of uniform size. The size of the crushed stones is 40 mm. The size of the crushed stones must be larger than the honeycomb hole 10 of the steel pipe. They are evenly spread in a square soil pit with a side length of 1200 mm (the rigid waterproof casing is covered with Buried underground), wherein water can gather rapidly, and can effectively prevent sundries from entering the water collector, avoiding that the wate...

Abstract

The invention discloses a method for installing and blocking a dewatering device in a foundation pit, comprising the following steps: manufacturing an aquifer; burying a water collector in the aquifer; setting a water pump inside the water collector; The upper end of the formwork is wrapped with rubber and plastic insulation cotton, and then wrapped tightly with sealing tape; the concrete surrounding the water collector and rubber and plastic insulation cotton is formed; the rubber and plastic insulation cotton is removed; the sealing device is formed; finally, the water collection well is formed with concrete. The method is suitable for high and low water pressure drop drainage in foundation pits. The method has strong practicability, good application effect and strong durability, and can effectively guarantee the later stage waterproofing, cushioning and concrete construction quality.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a method for installing and blocking a dewatering device in a foundation pit during construction. Background technique [0002] With the continuous improvement of the current architectural design level, the continuous development of construction technology, and the improvement of the requirements for building functions, more and more architectural designs now tend to be high-rise, super high-rise and accompanied by multi-storey basement structures. the design of. At the same time, the construction of water collection and drainage during the foundation construction stage is becoming more and more common. At present, the precipitation in the construction stage mostly adopts open ditches and open drains, which has limitations in construction. The sealing method of the later stage has caused the quality of the later waterproof, cushion, and concrete construction to ...
