A water-rich deep foundation pit drainage device according to claim 5, characterized in that the water outlet pipe (30) is arranged through the cover plate (22), and one end of the water outlet of the water outlet pipe (30) is connected to the outside. Water pump (28), the water outlet is higher than the ground (1); the cover plate (22) and the waterproof frame (27) are detachably connected to the water collecting tube. 7. A water-rich deep foundation pit drainage device according to claim 5, characterized in that the cleaning scraper (42) is two relatively symmetrical rectangular plates, and the inner side of the cleaning scraper (42) is larger than the outer side. Slightly narrower, the shape of the cleaning scraper (42) is an arc-shaped surface and matches the outer water collecting tube (45). A cleaning brush (26) is installed on the inside of the cleaning scraper (42). 8. A water-rich deep foundation pit drainage device according to claim 5, characterized in that the cleaning sheet (31) is a pentagonal sheet, and the bottom end of the pentagonal sheet is wide and thick. The top is pointed and can cooperate with the cleaning brush (26) to fully clean; the cleaning pieces (31) are arranged in an array on the outer surface of the inner water collecting tube (43), and the bottom end is in contact with the outer water collecting tube (45). ) The holes at the connection are slightly surplus to ensure that the cleaning piece (31) can vibrate within a certain range. 9. A water-rich deep foundation pit drainage device according to claim 5, characterized in that the cleaning brush (26) is slightly longer than the cleaning piece (31), and the cleaning brush (26) is connected to the cleaning piece. When the scrapers (42) rotate together, the cleaning brush (26) can sweep across the top tip of the cleaning piece (31). 10. A construction method for water-rich deep foundation pit (2) drainage collection, which is characterized by including: The first step is to install the fixing frame (5): Install the fixing frame (5) on the ground (1), and install and fix the fixing frame (5) across the foundation pit (2). For ease of operation, start The second motor (11) moves the moving mechanism to one end close to the ground (1), starts the hydraulic press (14) to shorten the hydraulic rod, and the horizontal plate (17) is lifted thereby; The second step is to place the working mechanism: Excavate a tank with a size that matches the working mechanism in the deep foundation pit (2). Place the water pump (28), water inlet pipe (29), water outlet pipe (30), and waterproof frame in the working mechanism. (27) After installation, place the entire working mechanism in the tank. The position of the working mechanism should be aligned with the center line of the upper moving mechanism; The third step is to install the connecting parts and cleaning parts: pass the cylindrical scale (4) through the center through hole of the horizontal plate (17) and fix it, and fix the driven gear (19) on the upper part of the cylindrical scale (4). ) meshes with the transmission gear (20), a right-angle connection block (40) and a nut (41) are installed at the lower end of the cylindrical scale (4), and a horizontal nut (41) set controls the right-angle connection block (40) and The contact tightness of the cylindrical scale (4), the vertical nut (41) set is fixed on the cover plate (22); the rotating rod (24) and the connecting piece (24) are installed through the center hole of the cover plate (22) 25), clean the scraper (42) and the cleaning brush (26), fasten the cover plate (22) and the outer water collecting tube (45) and seal it firmly; The fourth step is to start the device: the second motor (11) starts and controls the moving mechanism to move to the appropriate position. The hydraulic press (14) controls the hydraulic rod to control the working mechanism to move up and down. The first motor (12) starts synchronously to control the driven gear ( 19) Forward and reverse rotation drives the cleaning scraper (42) and cleaning brush (26) to work. The motor in the water collection barrel controls the vibration of the cleaning piece (31), and the device performs water collection and drainage operations.
