Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a dewatering and draining structure for a building foundation pit. Background Art

[0002] The purpose of building foundation pit dewatering is to address the impact of groundwater on construction during foundation pit construction, ensuring construction safety and project quality. During the excavation process, groundwater may sometimes be encountered, causing groundwater to seep into the foundation pit, resulting in water accumulation at the bottom of the foundation pit, affecting the next step of construction. At this time, drainage treatment is required inside the foundation pit.

[0003] In the existing technology, some drainage structures usually use water pipes for extraction when draining water. However, the depths of foundation pits vary, and it is impossible to ensure that the pipes reach the bottom after entering the foundation pits. As a result, the accumulated water is not discharged thoroughly. Therefore, a dewatering and drainage structure for building foundation pits is proposed to solve the above problem.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 2 The utility model provides an embodiment: a dewatering and drainage structure for a building foundation pit, including a pit body 1. The pit body 1 is the basic part of the entire drainage system and is used to collect and store accumulated water. A water pump 2 is fixedly connected to the left side of the top of the pit body 1 as a power source to ensure that the water pump 2 can effectively extract the accumulated water. The input end of the water pump 2 is fixedly connected to a pumping pipe 3, and the other end of the pumping pipe 3 is fixedly connected to a fixed head 4. The pumping pipe 3 is a channel connecting the water pump 2 and the fixed head 4, allowing the accumulated water to flow.

[0032] Reference Figure 3 The bottom of the fixed head 4 is fixedly connected with a pumping head 5, which is used to fix the pumping head 5. An elastic component is provided inside the fixed head 4, which can prevent the pumping head 5 from being blocked. The elastic component includes a connecting pipe 6, which is the main channel for water flow. The outside of the connecting pipe 6 is fixedly connected to the inside of the fixed head 4. The pumping head 5 is the part that directly contacts the accumulated water and is responsible for sucking water into the connecting pipe 6.

[0033] A cavity 7 is provided inside the connecting pipe 6, and a block 8 is slidably connected to the inside of the cavity 7, which moves up and down under the influence of water pressure. A return spring 10 is provided on the outside of the block 8, and one end of the return spring 10 is fixedly connected to the outside of the block 8. It is compressed when subjected to force, and pushes the block 8 back to its initial position after release. It is used to accommodate the block 8 and the return spring 10, forming a variable diameter to control the water flow.

[0034] The other end of the return spring 10 is fixedly connected to the inner wall of the cavity 7, and the bottom of the block 8 is fixedly connected with a gasket 9, which moves with the block 8 and works together with the block 8 to adjust the size of the water flow. The outside of the gasket 9 is slidably connected to the inner wall of the cavity 7 to enhance the sealing effect. The outside of the water pumping pipe 3 is fixedly connected to a fixing frame 11, and the outside of the fixing frame 11 is fixedly connected to multiple ropes 12 for supporting the ropes 12. The other end of the rope 12 is fixedly connected to a float 13 to transmit the position information of the float 13 for easy monitoring and adjustment. It floats up and down with changes in water level, and the position of the pumping head 5 is displayed through the rope 12.

[0035] Reference Figure 4 A chamber 14 is provided inside the pit body 1, and the bottom of the pumping head 5 is in contact with the inner wall of the chamber 14. A guide assembly is provided inside the pit body 1, which can assist in the discharge of accumulated water. The guide assembly includes a baffle 15, and the bottom of the baffle 15 is fixedly connected to the top of the chamber 14. A plurality of drainage pipes 16 are fixedly connected to the inside of the baffle 15, which are placed at an angle, which is conducive to draining the accumulated water between the pit body 1 and the baffle 15 into the inside of the chamber 14. A side groove 17 is provided inside the pit body 1, and the outside of the drainage pipe 16 is in contact with the inside of the side groove 17, ensuring smooth drainage, increasing the drainage area, and improving the drainage efficiency.

[0036] Working principle: First, place the pit body 1 in a suitable position, and then place the pumping pipe 3 into the interior of the pit body 1. As the pumping pipe 3 moves, the pumping head 5 will enter the interior of the chamber 14. At the same time, the float 13 will float upward under the action of water pressure. The staff can use the float 13 to monitor the position of the pumping head 5. Then, start the water pump 2. Driven by the water pump 2, the accumulated water enters the interior of the connecting pipe 6 through the pumping head 5. At this time, the gasket 9 and the return spring 10 are forced to compress upward, and the return spring 10 is also forced to compress. As a result, a gap is formed between the connecting pipe 6 and the cavity 7, and the accumulated water can pass through smoothly, avoiding the backflow of accumulated water while reducing blockage. Since the drainage pipe 16 is placed at an angle, it is beneficial to discharge the accumulated water between the pit body 1 and the baffle 15 into the interior of the chamber 14.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
