Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1 or 2, in the present embodiment, a basement anti-floating structure for reusing underground water includes a foundation layer 1, a basement body 2 disposed in the foundation layer 1, and a water pumping device disposed on the foundation layer 1, and further includes a water collecting pit 4 and a water seepage channel 3 disposed adjacent to the basement body 2 in the foundation layer 1. The water collecting pit 4 is preset with a water inlet pipe 41 communicated with the water seepage channel 3, wherein a filter screen 42 is arranged at a water inlet of the water inlet pipe 41 communicated with the water seepage channel 3.

In the present embodiment, the pumping device includes a pumping pump 54, a pumping pipe 55, a pumping tank 51 and a water outlet pipe 52, wherein a water outlet pipe 53 is preset at the lower side of the pumping tank 51. One end of the pumping pipe 55 is communicated to the upper side of the pumping tank 51 through the pumping pump 54, the other end of the pumping pipe 55 extends into the foundation layer 1 and is communicated with the sump 4, and the other end of the pumping pipe 55 extends to the bottom of the sump 4 in the sump 4. The water outlet pipe 52 and the water outlet pipe 53 are respectively provided with a first valve 56 and a second valve 57, the water outlet pipe 52 and the water outlet pipe 53 are controlled to be closed or opened through the first valve 56 and the second valve 57, wherein the first valve 56 and the second valve 57 are in a normally closed state. One end of outlet pipe 52 extends into foundation 1 and is communicated with inlet pipe 41, and the other end of outlet pipe 52 is communicated with the lower side of pumping tank 51.
