[0029] The present application will be further elaborated in detail below with reference to the accompanying drawings and embodiments.

[0030] Referring to Figures 1 to 4 , an earthwork foundation pit drainage structure is provided in an embodiment of the present application, including a bottom plate 1. A vertical rod 4 is fixedly installed on the top of the bottom plate 1. A pumping assembly 2 is arranged on the top of the bottom plate 1. An anti-blocking assembly 3 is arranged on the outer side of the vertical rod 4. The pumping assembly 2 includes a filter box 21. The filter box 21 is fixedly installed on the front of the vertical rod 4. An intermediate plate 25 is arranged on the left side of the filter box 21. A filter groove plate 26 is formed inside the intermediate plate 25. Extension plates 24 are fixedly installed on both the front and rear sides of the intermediate plate 25. The anti-blocking assembly 3 includes a T-shaped sliding rod 34. The T-shaped sliding rod 34 is fixedly installed on the top of the bottom plate 1. A push plate 35 is slidably connected between the outer sides of the T-shaped sliding rod 34. The push plate 35 is fixedly installed between the bottom of the extension plate 24 and the intermediate plate 25.

[0031] The inside of the filter box 21 is hollow. A stainless steel pipe 22 is fixedly installed on the top of the filter box 21. A plastic hose 23 is fixedly installed on the top of the stainless steel pipe 22. The inside of the filter box 21, the stainless steel pipe 22, and the plastic hose 23 are interconnected. The filter box 21 has an oblique cutting part, and the oblique cutting part forms a material suction port. The water to be drained in the foundation pit and the connected impurities enter the drainage structure through the material suction port. The intermediate plate 25 is attached to the outer side of the hypotenuse of the filter box 21. The filter box 21 communicates with the inside of the filter box 21 and the outside through the filter groove plate 26.

[0032] The oblique cutting part is obliquely cut from an upper edge of the filter box 21 to a lower diagonal edge, thereby forming the oblique cutting part.

[0033] A steel cable 5 is fixedly installed on the top of the vertical rod 4. Bottom pads 6 are fixedly installed at the four corners of the bottom of the bottom plate 1.

[0034] In this embodiment, when in use, the whole device is lowered into the foundation pit through the steel cable 5. A mud pump is externally connected through the plastic hose 23. By starting the mud pump and cooperating with the plastic hose 23 and the stainless steel pipe 22, suction is generated inside the filter box 21. After the suction is generated, the external water and mud are sucked into the filter box 21 and then enter the mud pump through the stainless steel pipe 22 and the plastic hose 23 and are discharged through the mud pump, achieving the effect of discharging the accumulated water and the mud in the accumulated water inside the foundation pit. And when discharging, the large-particle impurities in the sucked water and mud are filtered through the filter groove plate 26 inside the intermediate plate 25 to prevent the large-particle impurities from entering the mud pump and causing damage to the mud pump. And the obliquely designed filter groove plate 26 ensures that the filtered impurities can better fall above the bottom plate 1 under the action of gravity, preventing the impurities from blocking the inlet.

[0035] Referring to Figures 1 to 4, in one aspect of this embodiment, the anti-blocking assembly 3 further includes a support block 31. The support block 31 is fixedly installed on the back of the vertical rod 4. A support rod 32 is fixedly installed on the back of the support block 31. An electric push rod 33 is hinged between the support rod 32 and the corresponding extension plate 24 in the front. The two electric push rods 33 are respectively located on the left and right sides of the vertical rod 4. The two electric push rods 33 are both waterproof electric push rods. The two electric push rods 33 have exactly the same model parameters. The two electric push rods 33 are controlled by a synchronous controller to start and stop synchronously.

[0036] In this embodiment, the wiring cable of the electric push rod 33 is also a waterproof cable. The waterproof cable is externally connected to a power supply device and a synchronous controller. Through the synchronous controller, the electric push rods 33 on both sides can be controlled to run synchronously. When a certain amount of large particle impurities accumulate below the middle plate 25 and affect the water pumping, at this time, the mud pump is turned off, and the electric push rod 33 is started. After the electric push rod 33 is unfolded, it pushes the extension plate 24 forward. When pushing, the middle plate 25 and the push plate 35 are connected and move forward synchronously. The accumulated impurities are pushed forward through the middle plate 25, the extension plate 24 and the push plate 35, and then reset after pushing, so as to realize moving the impurities accumulated below the filter trough plate 26 forward, ensuring the smooth flow of water near the filter trough plate 26, and solving the problem that the impurities will accumulate more and more, which will further affect the discharge of water and mud; and when the middle plate 25 moves outwards, since the mud pump is not working and the impurities are not affected by the external suction force, the impurities will not enter the interior of the filter box 21 through the gap between the middle plate 25 and the filter box 21.

[0037] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] Working principle: During use, the entire device is lowered into the foundation pit through the steel cable 5. The plastic hose 23 is externally connected to a slurry pump. By starting the slurry pump and cooperating with the plastic hose 23 and the stainless steel pipe 22, suction is generated inside the filter box 21. After the suction is generated, external water and slurry are sucked into the filter box 21, then enter the slurry pump through the stainless steel pipe 22 and the plastic hose 23, and are discharged through the slurry pump, achieving the effect of discharging the accumulated water and slurry in the foundation pit. And when discharging, the large-particle impurities in the sucked water and slurry are filtered by the filter trough plate 26 inside the intermediate plate 25 to prevent the large-particle impurities from entering the slurry pump and causing damage to the slurry pump. Moreover, the inclined filter trough plate 26 ensures that the filtered impurities can better fall onto the upper side of the bottom plate 1 under the action of gravity, preventing the impurities from blocking the inlet. The wiring cable of the electric push rod 33 is also a waterproof cable, and the waterproof cable is externally connected to a power supply device and a synchronous controller. Through the synchronous controller, the two-sided electric push rods 33 can be controlled to run synchronously. When a certain amount of large-particle impurities accumulate below the intermediate plate 25 and affect the water pumping, at this time, the slurry pump is turned off, and the electric push rod 33 is started. After the electric push rod 33 is extended, the extension plate 24 is pushed forward. When pushing, the intermediate plate 25 and the push plate 35 are connected and move forward synchronously. The accumulated impurities are pushed forward through the intermediate plate 25, the extension plate 24, and the push plate 35, and then reset, thus realizing the forward movement of the impurities accumulated below the filter trough plate 26, ensuring the smooth flow of water near the filter trough plate 26, and solving the problem that the impurities will accumulate more and more, which will further affect the discharge of water and slurry. And when the intermediate plate 25 moves outward, since the slurry pump is not working and the impurities are not affected by the external suction force, the impurities will not enter the filter box 21 through the gap between the intermediate plate 25 and the filter box 21.
