Description

TECHNICAL FIELD

[0001] The application relates to the technical field of water conservancy projects, in particular to an auxiliary device for water pumping of a sand layer foundation by a water pump. BACKGROUND

[0002] In water conservancy project construction, a cofferdam needs to be filled and constructed for staged diversion construction in the early stage, and after the cofferdam is filled and constructed, water in the cofferdam foundation pit, the foundation part of the proposed building and the surrounding water are pumped out by a water pump. According to the understanding, the existing water pumping mode mainly selects a suitable water pump type and specification according to the actual situation and needs of the construction site, and the water pump is directly installed in the low-lying area of the foundation pit, and the installation position of the water pump needs to be manually moved along with the continuous lowering of the water pumping surface. Especially in the sand layer area, the pump pipe of the water pump is more likely to be blocked and dead, which affects the water pumping speed and even cannot continue the water pumping work. Thus, the construction process is slowed down, and uncontrollable factors of the foundation construction are increased. At the same time, there is a safety risk in manually moving the water pumping position.

[0003] Therefore, the application provides an auxiliary device for water pumping of a sand layer foundation by a water pump, which isolates and protects the water pump pipe opening to prevent the pipe from being blocked, and workers do not need to move close to the water pump to transfer the water pumping position, thereby reducing the engineering risk.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Figures 1-7 The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0028] In order to solve the problems in the prior art, the present application provides an auxiliary device for water pumping of sand layer foundation, which comprises a hanging frame 1, and a moving frame 2 vertically slidingly installed on the hanging frame 1. The hanging frame 1 and the moving frame 2 each comprise four vertical columns and connecting columns between the four vertical columns. The vertical columns and the connecting columns of the hanging frame 1 and the moving frame 2 are each spliced by galvanized square tubes through welding or fastening. The vertical columns of the moving frame 2 are inserted into the vertical columns of the hanging frame 1 to achieve the purpose of moving the moving frame 2 along the vertical column height direction. In order to keep the moving frame 2 stable after moving, the four vertical columns of the moving frame 2 are each vertically spaced apart and provided with a plurality of through holes 13, and the upper end of the vertical column of the hanging frame 1 is welded and fixed with a nut 14 penetrating through the side wall of the hanging frame 1. The nut 14 and one of the through holes 13 are jointly connected with a bolt 15. Through the fastening cooperation of the bolt 15 and the nut 14, the moving frame 2 is braked and limited.

[0029] A cross frame 3 is welded and fixed to the upper end of the moving frame 2, and the cross frame 3 is also made of galvanized square tubes. The center of the cross frame 3 is provided with a socket, and a screw rod 4 is inserted into the socket and penetrates through the socket at both ends. The lower end of the screw rod 4 is integrally provided with a lifting ring 6, and the lifting ring 6 is provided with a convex ring abutting against the lower end of the cross frame 3. A self-locking nut 5 is screwed onto the upper end of the screw rod 4 and abuts against the upper end surface of the cross frame 3. The self-locking nut 5 is provided with at least two. A hoist 7 is hung on the lifting ring 6, and the hoist 7 is any one of a manual or electric hoist 7. A water pump 8 is hung on the hoisting end of the hoist 7. A trash screen 9 made of steel wire mesh is arranged around the lower end of the hanging frame 1. The trash screen 9 is connected by wire tying at the joint after one turn around the hanging frame 1. Similarly, a plurality of tying sections are provided between the vertical column of the hanging frame 1 and the trash screen 9 by wire tying, so that the trash screen 9 is bound and fixed on the hanging frame 1.

[0030] A plurality of screw sleeves 10 are welded and fixed to the periphery of the lower end surface of the hanging frame 1. Screw posts are screwed and installed in the screw sleeves 10, and ground anchors 11 are integrally provided at the lower ends of the screw posts. The ground anchors 11 are of a pointed plug-in structure.

[0031] The hanging frame 1 is provided with a grounding wire 12.

[0032] According to the above technical scheme,

[0033] In use, the lifting frame 1 is lifted into a low-lying area by a crane or other mechanical device in cooperation with manual work. The ground anchor 11 is inserted into the mud to stabilize the lifting frame 1. Then the water pump 8 is pulled to below the water surface by the hoist 7, and the leakage grounding wire 12 is connected. As the water pump 8 continuously pumps, the water level drops, and the height of the water pump 8 is adjusted by the hoist 7 to adapt to the continuously dropping water level. The pulling point of the hoist 7 is in a safe area outside the water hole, and it is not necessary to be close to the side of the water hole to avoid sinking into the soft geological area of the side of the water hole, thereby improving the safety in use. The trash screen 9 around the lifting frame 1 isolates and wraps the inside of the lifting frame 1, so that the floating objects and large stones in the water hole are isolated, thereby avoiding the blockage of the pipeline of the water pump 8 to ensure the continuous pumping operation. The extension and cooperation between the lifting frame 1 and the movable frame 2 can adjust the maximum lifting height of the water pump 8 to adapt to the pumping operation of the water hole of different depths to the greatest extent. After the grounding of the grounding wire 12 provided on the lifting frame 1, the leakage point can be prevented, and the safety in use is improved.

[0034] The ground anchor 11 and the lifting frame 1 are detachably connected through the cooperation of the screw sleeve 10 and the stud, which facilitates disassembly and maintenance when problems such as bending and rust occur.

[0035] Preferably, the movable frame 2 is bundled with an isolation screen cover by a wire, and the isolation screen cover is close to the inner wall of the lifting frame 1. The isolation screen cover can be lifted synchronously with the movable frame 2, thereby forming an isolation belt at the leakage position above the water surface, so as to isolate the floating debris such as leaves and branches, and avoid the penetration of the debris from the gap above the lifting frame 1 into the inside to be sucked into the water pump 8 and cause blockage.

[0036] Preferably, the movable frame 2 is bundled with an isolation screen cover by a wire, and the isolation screen cover is close to the inner wall of the lifting frame 1. The isolation screen cover is close to the inner wall of the isolation screen cover. The height of the isolation screen cover is close to the movable frame 2. Under the cooperation of the trash screen 9 and the isolation screen cover, the periphery of the lifting frame 1 and the movable frame 2 is wrapped, the dead angle and gap of the isolation and protection are reduced, and the penetration of the floating debris from the gap into the water pump 8 is prevented.

Any person skilled in the art can make equivalent replacement or change according to the technical range disclosed in the present application and the application concept of the present application, which should be covered within the protection scope of the present application.
