[0015] A method for using a foundation pit dewatering and drainage integrated system comprises the following steps:

[0016] S1: When it rains, rainwater falls on the roof and is discharged through the drainage floor drain set on the roof. The rainwater flows into the second gravity water pipe through the drainage floor drain and is finally discharged into the second water storage tank for collection. When the water is discharged, impurities are filtered out by the filter. When the rainwater is heavy, the rainwater that cannot be discharged by the drainage floor drain flows into the sump and is discharged into the second water storage tank through the first gravity water pipe;

[0017] S2: After part of the rainwater seeps into the ground, it will enter the precipitation well and cause the water level to be too high. A water pump is placed in the precipitation well for precipitation. The water level is sensed by a sensor. When the water level exceeds the warning level, a control signal is sent to the water pump through the sensor to make it work and pump water. After the water level drops from the warning line, a stop signal is generated by the sensor to control the water pump to stop. The pumped water is transported to the first water tank for storage. The water volume of the first water tank is detected based on the water level sensor. When a large amount of water is detected, the water pump is controlled to start and transfer the water flow to the second water tank.

[0018] S3: When the water level sensor detects that there is more water in the second water storage tank, the stored water is transferred to the main water storage tank, and filtered by the filter tank. The water after filtration is transported through the outlet pipe for use. The filter cartridge is rotated by the speed regulating motor, and the cleaning brush is controlled by the hydraulic telescopic rod to move and contact the filter cartridge for cleaning. The connecting pipe connects the pipeline for flushing and sewage discharge.

[0019] S4: Control the hydraulic lifting rod to start adjusting the scraper position so that the scraper contacts the filter screen, and control the scraper to contact the filter screen through the rotating motor to clean the impurities.

[0020] The beneficial effects of the present invention are:

[0021] 1. By setting up a filter cartridge, the collected and stored water can be effectively filtered, so that the collected water quality can meet the standard for reuse, which can solve the problem that the traditional method cannot be used and the water quality does not meet the standard. After a certain period of use, the filter holes of the filter cartridge will be blocked. The transmission shaft and the filter cartridge can be controlled to rotate by starting the speed regulating motor. When the filter cartridge rotates, the attached dirt and impurities can be thrown off. At the same time, when the filter cartridge rotates, the hydraulic telescopic rod controls the cleaning brush to fall and contact the filter cartridge. The cleaning brush contacts the rotating filter cartridge to assist in cleaning it, which can effectively remove the attached stubborn dirt, thereby solving the problem of filter hole blockage. The two sets of connecting pipes can be connected to the water supply pipe and the sewage pipe respectively, so that water can be injected into the filter bin for flushing and sewage discharge, thereby avoiding the accumulation of a large amount of impurities and dirt in the filter bin that affects the filtration.

[0022] 2. After long-term use, certain impurities will adhere to the filter, causing blockage and affecting normal drainage. The hydraulic lifting rod can be used to control the scraper to fall and contact the filter. The rotating motor can be used to control the scraper to contact the filter and rotate it to clean it, avoiding the situation where the filter is completely blocked by impurities and affecting drainage.

[0023] 3. After the limit frame is fixed, the fixing cone can be inserted through the limiting hole of the limit frame, and the fixing cone can be nailed into the ground using tools to complete the reinforcement of the limit frame, which can avoid displacement or tilting of the installed limit frame, thereby providing effective support and protection for the supporting wall.

When encountering rainy weather, rainwater flows through the top plate 14, and the rainwater can be discharged through the drainage floor drain 32 during the flow, thereby avoiding water accumulation on the top plate 14. After the rainwater enters the drainage floor drain 32, it flows into the second water storage tank 12 through the second gravity water pipe 31 by gravity for storage. When the storage is large, the delivery pump in the second water storage tank 12 is started to deliver the collected rainwater through the second water delivery pipe 29 to the main water storage tank 28 for use.

The filtered water can be used for on-site sprinkling and dust reduction, vehicle washing, and production and living water. The used waste water is collected again and treated and reused, saving water resources. At the same time, the filtered water can be used for re-injection to keep the water level outside the foundation pit balanced. The filter cartridge 34 will be blocked after being used for a long time. The filter cartridge 34 can be controlled to rotate by the speed regulating motor 21. The cleaning brush 33 is controlled by the hydraulic telescopic rod 23 to contact the rotating filter cartridge 34 to clean it and remove the blocked impurities.

A method for using the foundation pit dewatering and drainage integrated system according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: When it rains, rain falls on the top plate (14), and is drained through the drainage floor drain (32) provided on the top plate (14). The rain flows through the drainage floor drain (32) into the second gravity water pipe (31) and is finally discharged into the second water storage tank (12) for collection. When the water is drained, impurities are filtered out by the filter net (13). When the rain is heavy, the rain that cannot be drained by the drainage floor drain (32) flows into the sump (15) and is discharged into the second water storage tank (12) through the first gravity water pipe (30); S2: After part of the rainwater seeps into the ground, it will enter the precipitation well and cause the water level to be too high. The water pump (9) is placed in the precipitation well to perform precipitation. The water level is sensed by a sensor. When the water level exceeds the warning level, a control signal is sent to the water pump (9) through the sensor to make it work and pump water. When the water level drops from the warning line, a stop signal is generated through the sensor to control the water pump (9) to stop. The pumped water is transported to the first water storage tank (10) for storage. The water volume of the first water storage tank (10) is detected based on the water level sensor. When a large amount of water is detected, the water pump is controlled to start and transfer the water flow to the second water storage tank (12); S3: When the water level sensor detects that the amount of water in the second water storage tank (12) is relatively large, the stored water is transferred to the main water storage tank (28), and filtered by the filter chamber (22).
