[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Example

[0020] See also Figure 1-3 The utility model provides a technical solution: a water supply and drainage device for a deep foundation pit, comprising a shell 1, a plurality of filter holes 2 are evenly opened on the top of the shell 1, a connecting plate 3 is provided on the top of the shell 1, arc plates 5 are respectively installed at both ends of the connecting plate 3, a connecting tube 4 is installed in the middle of the connecting plate 3, and the connecting tube 4 passes through the upper surface of the shell 1;

[0021] A plurality of interconnected square water pipes 11 are installed on the bottom of the outer wall of the connecting tube 4 located inside the housing 1. A plurality of nozzles 12 are evenly installed on the square water pipes 11. A second submersible pump 15 is installed at the bottom of one of the square water pipes 11.

[0022] The connecting tube 4 is located in the middle of the outer wall inside the shell 1 and is evenly installed with multiple teeth 10. The inner top wall of the shell 1 is installed with a driving motor 8. The output shaft of the driving motor 8 is installed with a gear 9, and the gear 9 is meshed with the teeth 10.

[0023] like Figure 2 and Figure 3As shown: a first submersible pump 14 is installed on the inner bottom wall of the shell 1, and a connecting pipe 7 is connected to the water outlet of the first submersible pump 14, and the connecting pipe 7 runs through the interior of the connecting tube 4; through the above arrangement, the first submersible pump 14 can extract moisture from the inside of the foundation pit, and then discharge the accumulated water through the connecting pipe 7.

[0024] like Figure 1 and Figure 2 As shown: a slide rail 6 is installed on the outer wall of the shell 1, and a slide groove 13 is provided at the bottom of the arc plate 5, and the slide groove 13 is adapted to the slide rail 6; through the above settings, the mutual cooperation between the slide rail 6 and the slide groove 13 can limit the position of the arc plate 5, and at the same time make its movement more convenient and quick.

[0025] like Figure 1 and Figure 3 As shown: the arc plate 5 is attached to the outer side of the shell 1; through the above arrangement, the debris outside the filter hole 2 can be scraped off, thereby avoiding the filter hole 2 from being blocked.
