Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a drainage device for building construction. Background Art

[0002] Before construction, in order to improve the safety and stability of building construction, it is necessary to excavate underground foundation pits at designated locations. There will be a lot of water in the foundation pits due to groundwater and rainfall. If the base soil of the foundation pit is soaked in water for a long time, it will become soft, making it difficult to achieve the designed bearing capacity. Therefore, the foundation pit needs to be continuously drained.

[0003] In the Chinese utility model patent with publication number CN220395988U, a drainage device for construction site construction is provided, which can prevent the pumping pipe from being too close to the bottom of the water pit and the mud and sand in the water cooling from being sucked into the pumping pipe, and can also prevent large particles of mud and sand from entering the pumping pump to cause equipment damage or pipe blockage. However, in the actual construction process of pumping and draining water before the construction of the building foundation, it is found that the above-mentioned drainage device still has some defects and shortcomings: the device can only realize the pumping and drainage of a single foundation pit, and does not have the function of draining multiple foundation pits at the same time. During construction, it is often necessary to excavate multiple foundation pits at the same time, resulting in the need to use multiple devices, increasing the workload, and the practicality of the device is low. Therefore, it is urgent to improve the existing drainage device for construction site construction and provide a drainage device for construction that is convenient for draining multiple foundation pits at the same time.
