Description

Technical Field

[0001] This utility model relates to the technical field of foundation pit drainage devices, specifically a foundation pit drainage device for building construction projects. Background Technology

[0002] In the construction process of building projects, foundation pit excavation is a fundamental and crucial task. As the working space for foundation construction, the quality and construction conditions of the foundation pit have a significant impact on the stability and safety of the entire building project.

[0003] During the foundation pit construction phase, water often accumulates in the pit due to various factors such as groundwater and rainwater. To ensure the smooth progress of subsequent foundation construction and prevent the accumulated water from soaking and softening the foundation soil, thus affecting the bearing capacity, it is necessary to pump out the water from the pit in a timely manner. Currently, the commonly used method is to use a water pump in conjunction with a suction head, placing the suction head at the bottom of the pit to perform the pumping operation.

[0004] However, the actual environment of an excavation pit is quite complex, and in many cases, silt will be present at the bottom. During the pumping process, the silt will be drawn into the suction head along with the water flow, easily causing blockage. Once the suction head is blocked, the pumping efficiency will be greatly reduced, or it may even fail to work properly, resulting in the inability to effectively remove the water accumulated in the excavation pit. This will delay the construction progress and increase construction costs. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 The present invention discloses a foundation pit drainage device for building construction projects, comprising a base plate 1, with multiple evenly distributed insertion holes at the top edge of the base plate 1, and a ground nail 16 inserted into each insertion hole, thereby making the ground nail 16 slidably connected to the insertion hole. By using a tool to strike the ground nail 16, the ground nail 16 is inserted into the ground, thereby fixing the base plate 1 on the ground, so that the device is stable when in use.

[0020] A water pump 4 is installed on the top of the base plate 1. A connecting pipe 5 is installed on the water pump 4's suction end. A suction head 6 is installed on one end of the connecting pipe 5. The side wall of the suction head 6 is a filter screen to block foreign objects from entering the suction head 6, thereby preventing the water pump 4 from becoming clogged.

[0021] A sliding tube 3 is installed above the base plate 1. The sliding tube is horizontally positioned. Multiple connecting plates 2 connect the sliding tube 3 and the base plate 1, forming an installation space between the sliding tube 3 and the base. The water pump 4 is placed in the installation space.

[0022] The slide tube 3 has a lifting rod 7 inserted and can slide. One end of the lifting rod 7 is connected to a handle 17, and a rope hole is opened at the top near the other end. Several limiting grooves 14 are evenly distributed on the top of the lifting rod 7. The top of the slide tube 3 has an insertion hole, and an insertion plate 15 that matches the limiting groove 14 is inserted and connected to the insertion hole to prevent the lifting rod 7 from sliding on the slide tube 3, thereby adjusting the extension length of the lifting rod 7 on the slide tube 3.

[0023] A take-up drum 8 is fixedly connected to the top of the slide tube 3. A take-up rod 9 is rotatably connected inside the take-up drum 8. A connecting rope 10 is connected between the take-up rod 9 and the suction head 6 through a rope hole. A turntable 11 is installed on one side of the take-up rod 9. A rocker tube 12 connected to the other side of the turntable 11 is fixedly connected to the side wall edge of the turntable 11. A limit rod 13 is inserted into the rocker tube 12. When the suction head 6 reaches the suction position, the limit rod 13 is inserted into the rocker tube 12. The limit rod 13 blocks the top of the slide tube 3, so that the rotating rod is no longer rotated by the pull of the suction head 6.

[0024] In summary, when using the foundation pit drainage device for building construction projects, the device is moved to the edge of the foundation pit, and the ground nails 16 are driven into the ground using a tool to fix the device.

[0025] Pull out the limiting rod 13 from the rocker tube 12 and pull out the insert plate 15 from the slide tube 3. Hold the handle 17 and push the lifting rod 7 on the slide tube 3 so that the suction head 6 enters the middle of the pit. Then insert the insert plate 15 into the insertion hole of the slide tube 3 and insert the insert plate 15 into the limiting groove 14 to prevent the lifting rod 7 from sliding on the slide tube 3.

[0026] Under its own weight, the suction head 6 pulls the connecting rope 10, causing the winding rod 9 to release the connecting rope 10 and positioning the suction head 6 below the water in the pit, preventing the suction head 6 from entering the silt.

[0027] Then, a limiting rod 13 is inserted into the rocker tube 12. The limiting rod 13 is pulled by the connecting rope 10, and the end of the limiting rod 13 is placed on the top of the slide tube 3, thereby preventing the winding rod 9 from rotating and thus fixing the suction head 6.

[0028] Start water pump 4, suction head 6 draws water from the foundation pit, which enters water pump 4 through connecting pipe 5, and water pump 4 discharges water from the foundation pit.

[0029] Once the suction head 6 is exposed from the water in the pit, the limiting rod 13 is pulled out from the crank tube 12. The connecting rope 10 is pulled by the suction head 6, and the winding rod 9 releases the connecting rope 10, allowing the suction head 6 to enter a deeper position in the pit and be placed in the water. Then, the limiting rod 13 is inserted into the crank tube 12 to limit the suction head 6 again. By gradually releasing the suction head 6 downwards in the pit, the water in the pit is extracted layer by layer until the water in the pit is completely extracted.

[0030] After the water in the pit is pumped out, pull out the limiting rod 13 from the crank tube 12, hold the crank tube 12 and rotate it so that the winding rod 9 winds the connecting rope 10. The connecting rope 10 lifts the suction head 6 from the pit, making it easier to remove the suction head 6 from the pit.

[0031] Then remove ground nail 16 and store and move the device.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
