[0023] like Figure 1-5As shown, the utility model provides a water collection and drainage device for a deep foundation pit of a building construction, comprising a foundation pit body 1, a filtering assembly 2 and a water pumping pipe 10, characterized in that: a drainage channel 101 and a water collecting tank 102 are opened inside the foundation pit body 1, the drainage channel 101 is connected to the water collecting tank 102, the filtering assembly 2 comprises a square fence 201 and a filter box 202, the square fence 201 and the filter box 202 can effectively reduce the silt inside the water pumping pipe 10, a limiting assembly 3 is arranged between the square fence 201 and the filter box 202, the limiting assembly 3 comprises a limiting rod 301, the limiting rod 301 can limit the square fence 201 and the filter box 202, one end of the water pumping pipe 10 passes through the filter box 202, and the other end is fixedly connected to a water pump 4, one end of the water pump 4 is provided with a drainage assembly 5, the drainage assembly 5 comprises a sand storage box 501 and a baffle 502, and the baffle 502 can clean the silt in the sand storage box 501 when it moves vertically downward.

[0024] When the maintenance of the foundation pit body 1 is completed, the staff first installs the square fence 201 in the center of the water collection tank 102, so that the square fence 201 can resist silt and reduce the probability of silt entering the inside of the water pumping pipe 10 when pumping water. Then the filter box 202 is placed in the center of the square fence 201, and the external plate 304 is fitted with the top of the installation plate 302. After that, the limit rod 301 is passed through the limit hole 303 and the docking hole, and the limit rod 301 is pushed so that the limit rod 301 is gradually inserted into the soil, thereby improving the fixing effect of the structure, reducing the time of drainage affected by structural collapse, and thus improving drainage efficiency;

[0025] When water seeps from the inner wall of the foundation pit body 1, the seeped water can flow into the drainage channel 101. Since the drainage channel 101 is inclined, the water source will flow into the sump 102 through the drainage channel 101. The water source and the coarse sand therein can pass through the square fence 201 and then enter the filter box 202. The square fence 201 can filter the coarse sand and silt, so that the silt and coarse sand will not easily enter the filter box 202. Through multiple filtering methods, the probability of blockage of the pumping pipe 10 can be fully reduced, and the drainage efficiency can be improved. Then the water pump 4 is started. After the water pump 4 is in operation, the water source can be discharged into the sand storage box 501 through the water pumping pipe 10 and the drainage pipe 503. The water source can be directly discharged through the drainage end of the sand storage box 501, and the coarse sand will be screened in the sand storage box 501. When the drainage work is completed, the staff first places the collection equipment under the sand storage box 501, turns off the water pump 4, and drives the baffle 502 to move vertically downward. Then, under the action of gravity, the coarse sand can be directly discharged into the collection equipment, thereby improving the utilization rate of the coarse sand, reducing the probability of resource waste, and further improving applicability.

[0026] The drainage channel 101 is opened with a certain width, so that water can flow into the sump 102 through the drainage channel 101. The opening of the drainage channel 101 is a prior art and will not be explained here.

[0027] In one embodiment, the filter assembly 2 further includes a first filter screen 203 and a second filter screen 204 , a plurality of first filter screens 203 are fixedly mounted on the outer wall of the square fence 201 , and a plurality of second filter screens 204 are fixedly connected to the filter box 202 .

[0028] The water source can enter the filter box 202 through the first filter 203 and the second filter 204. At this time, under the filtering effect of the first filter 203 and the second filter 204, silt and coarse sand will not easily enter the filter box 202. Through multiple filtering methods, the probability of clogging of the water pump 10 can be fully reduced, and the drainage efficiency can be improved.

[0029] In one embodiment, the limiting assembly 3 also includes a mounting plate 302, a limiting hole 303, an external plate 304 and a docking hole. The mounting plate 302 is fixedly connected to the outer wall of the square fence 201. The limiting hole 303 is opened at the top of the mounting plate 302 and passes through the mounting plate 302. Several external plates 304 are fixedly connected to the outer wall of the filter box 202. The docking hole is opened on the external plate 304 and passes through the external plate 304. The limiting rod 301 passes through the limiting hole 303 and the docking hole.

[0030] The limiting rod 301 is passed through the limiting hole 303 and the docking hole, and the limiting rod 301 is pushed so that the limiting rod 301 is gradually inserted into the soil, so that the limiting rod 301 can limit the square fence 201 and the filter box 202 while improving the overall fixing effect of the structure, so that the structure can be used for a long time without frequent replacement, thereby improving drainage efficiency and applicability.

[0031] In one embodiment, the limit assembly 3 also includes a screw rod 306, a twist handle 307 and a connecting plate 308. The screw rod 306 is threadedly connected to the connecting plate 308 and is rotatably connected to the mounting plate 302. Several limit rods 301 are slidably matched with the connecting plate 308, and the twist handle 307 is fixedly connected to one end of the screw rod 306.

[0032] When the height of the foundation pit main body 1 is low and the connecting plate 308 cannot fit with the external plate 304, the staff rotates the screw 306, and the screw 306 is rotated and matched with the thread of the connecting plate 308. Under the guidance of several limiting rods 301, the connecting plate 308 can slide on the limiting rods 301 and fit with the top of the external plate 304 after moving a certain distance, thereby improving the limiting effect. By adjusting the position of the connecting plate 308, it can be suitable for foundation pits of different depths, thereby improving applicability.

[0033] In one embodiment, the drainage assembly 5 also includes a drainage pipe 503, a cylinder 504 and a connecting rod 505.

[0034] When the drainage work is completed, the staff first places the collection equipment under the sand storage box 501, turns off the water pump 4, and starts the cylinder 504. After the output end of the cylinder 504 is pushed out, it can push the baffle 502 to move vertically downward, and then under the action of gravity, the coarse sand can be directly discharged into the collection equipment, thereby improving the utilization rate of the coarse sand, reducing the probability of resource waste, and further improving applicability.

[0035] In one embodiment, a dustproof net 506 is fixedly installed on the top of the sand storage box 501 .

[0036] The dustproof net 506 can reduce dust on the surface of the sand storage box 501 and improve applicability.

[0037] The following is a detailed description of the working principle of the water collection and drainage device for deep foundation pits in construction:

[0038] When the maintenance of the foundation pit body 1 is completed, the staff first installs the square fence 201 in the center of the water collection tank 102, so that the square fence 201 can resist silt and reduce the probability of silt entering the inside of the water pumping pipe 10 during water pumping. Then, the filter box 202 is placed in the center of the square fence 201, and the external plate 304 is fitted with the top of the installation plate 302. Thereafter, the limit rod 301 is passed through the limit hole 303 and the docking hole, and the limit rod 301 is pushed so that the limit rod 301 is gradually inserted. In the soil, when the height of the foundation pit body 1 is relatively low and the connecting plate 308 cannot fit with the external plate 304, the staff rotates the screw rod 306, and the screw rod 306 is threadedly matched with the connecting plate 308 after rotation. Under the guidance of the limiting rods 301, the connecting plate 308 can slide on the limiting rods 301 and fit with the top of the external plate 304 after moving a certain distance, thereby improving the limiting effect. By adjusting the position of the connecting plate 308, it can be applied to foundation pits of different depths, thereby improving applicability.

[0039] When water seeps from the inner wall of the foundation pit body 1, the seeped water can flow into the drainage channel 101. Since the drainage channel 101 is inclined, the water source can flow into the water collection tank 102 through the drainage channel 101. The water source can enter the filter box 202 through the first filter screen 203 and the second filter screen 204. At this time, under the filtering effect of the first filter screen 203 and the second filter screen 204, silt and coarse sand will not easily enter the filter box 202. Through multiple filtering methods, the probability of clogging of the water pump 10 can be fully reduced, and the drainage efficiency can be improved. Then, the water pump 4 is started, and the water pump 4 operates. Finally, the water source can be discharged into the sand storage box 501 through the suction pipe 10 and the drainage pipe 503. The water source can be directly discharged through the drainage end of the sand storage box 501, and the coarse sand will be screened in the sand storage box 501. When the drainage work is completed, the staff first places the collection equipment under the sand storage box 501, turns off the water pump 4, and starts the cylinder 504. After the output end of the cylinder 504 is pushed out, the baffle 502 can be pushed to move vertically downward, and then under the action of gravity, the coarse sand can be directly discharged into the collection equipment, thereby improving the utilization rate of the coarse sand, reducing the probability of resource waste, and further improving applicability.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
