Description

Technical Field

[0001] The present application belongs to the technical field of foundation pit dewatering, and specifically relates to a dewatering treatment device for foundation pit construction. Background Art

[0002] Dewatering treatment during foundation pit construction refers to the need to remove rainwater from seepage or rainfall during the foundation pit excavation process to keep the inside of the foundation pit dry. There are mainly the following methods for foundation pit dewatering treatment: drainage pumps, drainage wells, underground drainage ditches, etc. When conducting foundation pit dewatering treatment, it is necessary to consider factors such as groundwater level, soil type, rainfall conditions, etc., and choose appropriate dewatering treatment methods to ensure the effectiveness and safety of foundation pit dewatering treatment.

[0003] For example, the utility model patent with announcement number CN219343271U discloses a green construction foundation pit closed dewatering device, including a support plate, a group of support legs are installed on the bottom surface of the support plate, a limiting component is installed on the bottom end of each support leg, a water pump is installed on the upper surface of the support plate, the output end of the water pump is connected to a water outlet pipe, a filter frame is fixedly inlaid on the bottom surface of the support plate, a group of filter nets are installed on the outer surface of the filter frame, and the input end of the water pump is located inside the filter frame. Through the coordinated arrangement of the support plate, the support legs, the limiting component, the water pump, the water outlet pipe, the filter frame, the filter net and the cleaning component, the water in the foundation pit is filtered through the filter net and enters the inside of the filter frame. The water pump can discharge the water when it is working, and the foundation pit can be dewatered. The cleaning component can automatically clean the filter net to avoid the blockage of the filter net by sand and gravel in the foundation pit, thereby ensuring the working efficiency of the dewatering device.

[0004] However, it was found in actual use that the device drives the reciprocating screw to rotate through the motor in the cleaning assembly, so that the cleaning frame and the brush can move left and right to clean the sand and gravel on the outer surface of the filter screen, and try to avoid the sand and gravel clogging the filter screen;

[0005] However, the material of the brush of the device is mostly soft, and the left and right movement of the brush cannot effectively brush off the sand and impurities adsorbed on the outer surface of the filter. When the cleaning frame and the brush push the sand and gravel to the side of the filter, the operation of the pump will generate negative pressure, forming a suction effect, which will cause the pushed sand and gravel and impurities and other particulate matter to re-attach to the filter, which will affect the foundation pit dewatering efficiency. For this purpose, a dewatering treatment device for foundation pit construction is provided. Utility Model Content

The waterproof motor 11 is a device that can be directly purchased in reality. This application only uses it without improving its structure, and no further elaboration is made here.

[0024] refer to Figure 1 , Figure 2 and Figure 3 A filter cartridge 7 is fixedly installed at the bottom end of the circular connecting block 5, and the bottom end of the drainage connecting pipe 2 extends to the inside of the filter cartridge 7. The outer surface of the filter cartridge 7 is provided with a plurality of filter holes 8 in a circular array. The filter cartridge 7 and filter holes 8 are arranged to block sand, gravel, impurities, etc. in the water body in the foundation pit, so as to avoid sand, gravel, impurities, etc. from clogging the pump as much as possible.

[0025] refer to Figure 1 , Figure 2 and Figure 3 An arc guide plate 9 is fixedly installed on the outer surface of the filter cartridge 7. Six arc guide plates 9 are arranged in a circular array on the outer surface of the filter cartridge 7, and the six arc guide plates 9 are made of stainless steel. A conical guide head 10 is fixedly installed on the bottom end of the filter cartridge 7. The six arc guide plates 9 and the conical guide head 10 can effectively guide sand and impurities in the water to the bottom of the filter cartridge 7, thereby reducing the filter cartridge blockage problem caused by the blockage of sand and impurities on the surface of the filter cartridge 7.

[0026] The implementation principle of the embodiment of the precipitation treatment device for foundation pit construction of the present application is as follows: the user first places the device in the accumulated water inside the foundation pit, and then connects the drainage connection pipe 2 to the drainage pipe of the external water pump through the flange connection plate 16. When the external water pump is started, negative pressure is generated to discharge the accumulated water inside the foundation pit through the drainage connection pipe 2 and the drainage pipe. When the accumulated water inside the foundation pit is discharged, the sand and impurities in the accumulated water will be blocked by the filter cartridge 7, so as to avoid the sand and impurities in the accumulated water inside the foundation pit from entering the pump and affecting it.

[0027] When the sand and impurities in the accumulated water are blocked by the filter cartridge 7, the personnel starts the waterproof motor 11 in the drive assembly 6, and the waterproof motor 11 drives the gear 12 to rotate. Since the gear 12 is meshed and connected with the outer gear ring 13, when the gear 12 rotates, it will drive the outer gear ring 13, the circular connecting block 5 and the filter cartridge 7 to rotate. When the filter cartridge 7 rotates and water flows through the arc guide plates 9 on the outer surface of the filter cartridge 7, these arc guide plates 9 will guide the sand and impurities downward along the surface of the filter cartridge 7, gradually bring them to the bottom of the filter cartridge 7, and under the action of the conical guide head 10 at the bottom of the filter cartridge 7, the sand and impurities are The sand and impurities further gather and deposit, so it is convenient to guide the sand and impurities to the bottom of the filter cartridge 7, which can effectively prevent the sand and impurities from accumulating and clogging the filter cartridge 7, and reduce the blockage of the filter cartridge 7 caused by the blockage of sand and impurities on the surface of the filter cartridge 7, thereby ensuring that the accumulated water in the foundation pit is discharged more smoothly and improving the efficiency of water precipitation in the foundation pit. The device has a simple structure and is easy to operate. Through the rotation of the filter cartridge 7, the arc guide plate 6 and the conical guide head, the sand and impurities close to the filter cartridge 7 can be guided to the bottom of the filter cartridge 7, which effectively avoids the accumulation of sand and impurities and improves the drainage efficiency.
