Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0026] Embodiment 1: This embodiment provides a drainage structure for a civil foundation pit. Figure 1-6 Specifically, it includes a foundation pit body 1, a pair of pumps 11 are fixedly arranged on the foundation pit body 1, a pair of sumps 12 are fixedly arranged at the bottom of the foundation pit body 1, and a pair of sumps 12 are provided with water collection ports 13 on both sides of the pair of sumps 12, a pair of sump tanks 14 are fixedly arranged at the bottom of the foundation pit body 1, and a plurality of water inlets 141 are provided on the sump tanks 14, a first filter screen 15 is fixedly arranged on both sides of the pair of sump tanks 14, a plurality of cover plates 16 are provided on the sump tanks 14, and the sump tanks 14 are respectively fixedly connected to the sump pits 12, and a pair of sump tanks 14 are provided at both ends. A slide 17 is provided, and a slider 18 is slidably provided in the slide 17. A second filter 19 is fixedly provided between each pair of sliders 18. An arc-shaped hook ring 111 is fixedly provided on the second filter 19. A connecting pipe 112 is fixedly provided on the water pump 11. A pair of limit rods 113 is fixedly provided in the sump 12. A floating plate 114 is slidably provided on each pair of limit rods 113. A filter head 115 is fixedly provided at the bottom of the floating plate 114. A hose 116 is fixedly provided on the filter head 115. The other end of the hose 116 is fixedly connected to the connecting pipe 112.
[0027] The filter heads 115 all pass through the floating plate 114, the filter heads 115 are located at the center of the floating plate 114, the sump 12 is located at the center of the short side of the foundation pit body 1, the bottom center of the foundation pit body 1 is slightly inclined to both sides, and multiple cover plates 16 completely cover the top of the sump 14. The connecting pipes 112 all pass through the sump 12, and a pair of sump 12 are arranged symmetrically. The bottom of the water inlet 141 is parallel to the bottom of the foundation pit body 1, the water collection ports 13 correspond to the end positions of the water collection ports 14, the second filter screens 19 are all located on one side of the water collection port 13, and the first filter screens 15 are at the same height as the water inlet 141.
[0028] In the specific implementation process, Figure 1 and Figure 4 As shown, when it rains, rainwater falling into the foundation pit body 1 flows toward the sump 14 through the slope, flows into the sump 14 through the first filter screen 15 and the water inlet 141, the first filter screen 15 filters a large amount of sediment in the rainwater, and flows to the sump 12 through the sump 14. The water in the sump 14 flows into the sump 12 through the second filter screen 19 and the water inlet 13 for collection. The second filter screen 19 can filter the sediment remaining in the rainwater again. When the second filter screen 19 is blocked, the second filter screen 19 can be removed from the sump 14 through the arc-shaped hook ring 111 through the slide 17 and the slider 18 for cleaning, and then inserted back for use again. When there is too much water in the water, the water pump 11 draws water from the sump 12 through the filter head 115 and injects it into the hose 116, and then discharges it from the water pump 11 through the connecting pipe 112. The floating plate 114 can increase or decrease the water level in the sump 12, so that the filter head 115 will not contact the settled mud and sand at the bottom of the foundation pit body 1, thereby preventing the suction of a large amount of mud and sand from affecting the use of the filter head 115. Through the coordinated use of the water pump 11, the sump 12, the sump 14, the first filter screen 15, the second filter screen 19, the connecting pipe 112, the floating plate 114, the filter head 115 and the hose 116, when the foundation pit body 1 is drained, the mud and sand can be effectively prevented from entering the water pump 11.
[0029] Embodiment 2: In Embodiment 1, there is still the problem that it is difficult for the staff to go down to the bottom of the sump to clean up the silt. Therefore, based on Embodiment 1, this embodiment also includes:
[0030] A protective cover 2 is rotatably provided on the sump 12 , a plurality of climbing poles 21 are fixedly provided on the inner wall of the sump 12 , and the plurality of climbing poles 21 are distributed in a linear upward vertical array, and a handle is fixedly provided on the protective cover 2 .
[0031] In the specific implementation process, Figure 2 and Figure 4As shown, after long-term use in the sump 12, when a large amount of mud and sand are deposited at the bottom of the sump 12, the protective cover 2 is opened, and the staff slowly descends to the bottom of the sump 12 through the climbing rod 21 to facilitate the cleaning of the mud and sand at the bottom of the sump 12. The climbing rod 21 facilitates the staff to enter and exit the sump 12. Through the coordinated use of the protective cover 2 and the climbing rod 21, when a large amount of mud and sand are deposited at the bottom of the sump 12 for a long time, the staff can go down to the bottom of the sump 12 through the climbing rod 21 to clean the mud and sand.
[0032] Specifically, the working principle and operation method of the utility model are as follows:

The water in the water collection tank 14 flows into the water collection pit 12 through the second filter screen 19 and the water collection port 13 for collection. The second filter screen 19 can filter the silt remaining in the rainwater again. When the second filter screen 19 is blocked, the arc-shaped hook ring 111 can be used to filter the silt that has passed through the second filter screen. 19, take it out from the water collection tank 14 through the chute 17 and the slider 18 for cleaning, and then insert it back for use again. When there is too much water in the water collection pit 12, start the water pump 11, and the water pump 11 pumps water from the water collection pit 12 through the filter head 115 and injects it into the hose 116, and then discharges it from the water pump 11 through the connecting pipe 112. The floating plate 114 can increase or decrease the water level in the water collection pit 12, so that the filter head 115 will not contact the sediment at the bottom of the foundation pit body 1, so as to prevent the suction of a large amount of sediment from affecting the use of the filter head 115;
[0034] Step 2: After a long period of use in the sump 12, when a large amount of silt is deposited at the bottom of the sump 12, the protective cover 2 is opened, and the staff slowly descends to the bottom of the sump 12 through the climbing rod 21 to clean the silt at the bottom of the sump 12. The climbing rod 21 facilitates the staff to enter and exit the sump 12, and the protective cover 2 can cover the top of the sump 12 for protection;
