Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit drainage, in particular to a foundation pit rapid drainage structure. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. The foundation pit support is a support, reinforcement and protection measure for the side walls of the foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. Groundwater control is also a part of the foundation pit support. In the foundation pit construction project, the aquifer is partly above the bottom of the trench. Therefore, after the earthwork is excavated to the bottom of the trench, hanging water may form on the slope wall and flow into the foundation pit. The existing foundation pit drainage method is to manually pump out the water in the foundation pit through a water pump, such as the publication number CN215367294U The patent discloses a quick installation structure for a foundation pit water supply and drainage device, including a sump and a submersible pump fixedly installed at the bottom of the sump. The side walls of the sump are provided with an inlet pipe or trench, and the upper part of the sump is provided with a steel cover or a concrete cover. The submersible pump is connected to the drain pipe through a sewage pipe. The sewage pipe adopts a hard pipe structure. A clamp joint is also provided in the sewage pipe connection of each submersible pump in the sump. The clamp joint is provided on the sewage pipe in the sump that is ≤ 20 cm away from the top plate. The float elevation of the submersible pump must be ≥ 20 cm lower than the clamp installation position. The device uses a submersible pump to pump water, but there is usually a large amount of mud and sand in the foundation pit, which can easily cause the water pump to clog. Moreover, it is difficult to clean the silt in the sump after pumping water.

[0003] To this end, the utility model provides a foundation pit rapid drainage structure. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a foundation pit rapid drainage structure, comprising a protective device installed in a foundation pit 1, the protective device comprising a foundation pit protective side plate 3 and a foundation pit protective bottom plate 4, a first drainage groove 5 is opened in the foundation pit protective bottom plate 4, a base 9 is installed in the first drainage groove 5, a first pipe 11 and a plurality of second pipes 12 are fixed on the base 9, a pumping device is installed on the foundation pit 1, the pumping device corresponds to the first pipe 11, and a plurality of water inlet pipes 6 are installed on the foundation pit protective side plate 3.

[0023] In this embodiment, the foundation pit protection side plate 3 and the foundation pit protection bottom plate 4 are both inclined structures, the first drainage trough 5 is slidably connected to the base 9, a water channel 10 is opened in the base 9, the water channel 10 is connected to the first pipe 11 and the second pipe 12, a filter screen 13 is fixed in the second pipe 12, a flange 14 is fixed at the end of the first pipe 11, the pumping device includes a water pump 2, the water pump 2 is fixed on the upper side of the foundation pit 1, a pumping pipe 15 is fixed to the water inlet end of the water pump 2, the end of the pumping pipe 15 corresponds to the flange 14, the end of the second pipe 12 is located at the top in the first drainage trough 5, and the end of the second pipe 12 is a conical structure.

[0024] Specifically, when there is more water in the foundation pit 1, the water in the foundation pit 1 can flow into the first drainage trough 5. At this time, the water flow carries mud and sand into the first drainage trough 5. The mud and sand settle in the first drainage trough 5, and the clean water slowly floats up until the clean water overflows the second pipe 12, allowing the clean water to enter the second pipe 12, and then the clean water enters the waterway 10 after being filtered through the filter screen 13. The filter screen 13 can filter out floating objects on the water, and the water pump 2 is started. The water pump 2 can pump water through the pumping pipe 15. The pumping pipe 15 is fixed to the first pipe 11, so that the pumping pipe 15 is connected to the waterway 10 through the first pipe 11, and water with less impurities in the waterway 10 can be extracted. The first drainage trough 5 is lower than the foundation pit protective bottom plate 4, which can ensure that the water in the foundation pit 1 except the first drainage trough 5 is pumped out.

[0025] When the water is pumped out, the pumping pipe 15 is removed, and then the first pipe 11 and the second pipe 12 are pulled upward to pull the base 9 upward, thereby pushing out the silt accumulated on the base 9 to prevent the silt from accumulating in the first drain trough 5.

[0026] A plurality of second drainage grooves 16 are provided in the foundation pit protection side plate 3, the second drainage grooves 16 are connected to the first drainage grooves 5, the water inlet pipe 6 is connected to the second drainage grooves 16, one end of the water inlet pipe 6 is located in the side wall of the foundation pit 1, a plurality of water inlets 8 are provided on the surrounding side of the water inlet pipe 6, a filter sleeve 7 is installed on the surrounding side of the water inlet pipe 6, and the filter sleeve 7 is filled with gravel.

[0027] Specifically, when water seeps into the side wall of the foundation pit 1, the water in the side wall of the foundation pit 1 can enter the water inlet pipe 6 through the water inlet 8 after being filtered by the filter sleeve 7, and then enter the second drainage trough 16 through the guidance of the water inlet pipe 6, and then flow into the first drainage trough 5, thereby preventing water from accumulating in the side wall of the foundation pit 1.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
