Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support and dewatering treatment, in particular to a foundation pit support and dewatering treatment structure. Background Technique

[0002] A foundation pit refers to a pit or trough excavated below the ground surface, usually used for the foundation preparation of construction projects such as buildings, bridges, tunnels, and underground facilities. The design and construction of the foundation pit are crucial for the safety and stability of the project. In order to ensure the stability and safety of the foundation pit construction, it is usually necessary to carry out support and dewatering treatment on the foundation pit.

[0003] In the traditional foundation pit support and dewatering treatment structure, drainage wells are used to collect and pump out the groundwater around or inside the foundation pit, usually equipped with water pumps. The deep well system is used to handle the dewatering in high water level areas, and the groundwater is pumped out through deep wells and water pumps. Retaining walls are set around the foundation pit to prevent soil from flowing into the foundation pit, and water level sensors are used to monitor the water level changes inside and outside the foundation pit in real time, providing data for adjusting the dewatering measures.

[0004] However, the fixed structure of the traditional foundation pit support and dewatering treatment structure is often a fixed pile. This single fixed structure may lead to poor dewatering treatment effect due to unstable fixation, reducing the stability and practicability of this structure. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a foundation pit support and dewatering treatment structure, aiming to improve the problem that the traditional foundation pit support and dewatering treatment structure may have poor dewatering treatment effect due to unstable fixation, reducing the stability and practicability of this structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a foundation pit support and dewatering treatment structure, including a drainage well, a plurality of fixed seats are fixedly connected to the side wall of the drainage well, a support platform is fixedly connected to the top of each fixed seat, an electric push rod I is fixedly connected to the upper surface of the fixed seat, an L-shaped rod is fixedly connected to the output end of the electric push rod I, a rotating plate I is rotatably connected inside the L-shaped rod, a rotating platform is fixedly connected to the upper surface of the support platform, a rotating plate II is rotatably connected to the outer wall of the rotating platform, one end of the rotating plate I is rotatably connected inside the rotating plate II, an L-shaped plate is rotatably connected to the outer wall of the rotating platform, a rotating plate III is rotatably connected inside the L-shaped plate, one end of the rotating plate III is rotatably connected to the outer wall of the rotating plate I, a pressing column is fixedly connected inside the L-shaped plate, and a drainage component is arranged at the bottom of the drainage well, and the drainage component is used to pump out the groundwater around or inside the foundation pit.

[0007] Furthermore, the drainage component includes a water pump, and the water pump is arranged at the bottom of the drainage well.

[0008] Furthermore, a plurality of drain pipes are fixedly connected to the outer wall of the drainage well, and a fixed platform is fixedly connected to one side of the outer wall of the drainage well.

[0010] Furthermore, the second side plate is slidably connected to the side wall of the fixed platform. Push frames are fixedly connected to both the electric push rod II and the top of the second side plate.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a foundation pit support and dewatering treatment structure, including a drainage well 1, a plurality of fixed seats 2 are fixedly connected to the side wall of the drainage well 1, support platforms 3 are fixedly connected to the tops of the fixed seats 2, electric push rods 1 are fixedly connected to the upper surfaces of the fixed seats 2, an L-shaped rod 5 is fixedly connected to the output end of the electric push rod 1, a rotating plate 7 is rotatably connected inside the L-shaped rod 5, a turntable 6 is fixedly connected to the upper surface of the support platform 3, a rotating plate 2 is rotatably connected to the outer wall of the turntable 6, one end of the rotating plate 7 is rotatably connected inside the rotating plate 2, an L-shaped plate 10 is rotatably connected to the outer wall of the turntable 6, a rotating plate 3 is rotatably connected inside the L-shaped plate 10, one end of the rotating plate 3 is rotatably connected to the outer wall of the rotating plate 7, a pressing column 11 is fixedly connected inside the L-shaped plate 10, a drainage assembly is arranged at the bottom of the drainage well 1, and the drainage assembly is used for pumping groundwater around or inside the foundation pit.

[0025] Specifically, this structure usually needs to be installed on the top of the foundation pit. By pumping the precipitation inside the foundation pit with the water pump 25, the effect of drying the inside of the foundation pit is achieved. First, start the electric push rod 1. Through its driving force, the L-shaped rod 5 performs a vertical lifting movement. Inside the L-shaped rod 5, there is a first rotating plate 7. As the L-shaped rod 5 lifts and lowers, the first rotating plate 7 also rotates accordingly, changing its angle. The rotation of the first rotating plate 7 enables the third rotating plate 9 on its outer wall to rotate inside the second rotating plate 8. The rotation of the first rotating plate 7 drives the rotation of the third rotating plate 9, thereby affecting the movement of the second rotating plate 8. The second rotating plate 8 is located inside the turntable 6. As the third rotating plate 9 rotates, the second rotating plate 8 also rotates inside the turntable 6. The cooperation relationship between the L-shaped plate 10 and the inside of the third rotating plate 9 is close. The rotation of the third rotating plate 9 causes the L-shaped plate 10 to rotate accordingly. The rotation of the L-shaped plate 10 causes the pressing column 11 inside it to move downward. The downward movement of the pressing column 11 exerts pressure on the soil near the foundation pit, thereby effectively fixing the positions of the drainage well 1 and the water pump 25 at its bottom. The positions of the drainage well 1 and the water pump 25 are effectively fixed, ensuring their stability in the foundation pit. The fixed water pump 25 can stably pump the groundwater around or inside the foundation pit, and discharge the pumped water through the drain pipe 12, and achieve the drying of the foundation pit through a stable drainage system, providing an important guarantee for construction safety.

[0026] Refer to Figure 3 , the drainage component includes a water pump 25. The water pump 25 is arranged at the bottom of the drainage well 1. A plurality of drain pipes 12 are fixedly connected to the outer wall of the drainage well 1. One side of the outer wall of the drainage well 1 is fixedly connected with a fixed platform 13. The side wall of the fixed platform 13 is slidably connected with a first side plate 14. The bottom of the first side plate 14 is fixedly connected with an electric push rod 2. The output end of the electric push rod 2 is fixedly connected with a second side plate 16. The second side plate 16 is slidably connected to the side wall of the fixed platform 13. Both the electric push rod 2 and the top of the second side plate 16 are fixedly connected with a push frame 17. The top of the fixed platform 13 is slidably connected with a push table 19. The upper surface of the push table 19 is fixedly connected with a fixed block 20. The upper surface of the fixed block 20 is rotatably connected with a connecting rod 18. One end of the connecting rod 18 is rotatably connected inside the push frame 17. A fixed column 21 is fixedly connected inside the fixed block 20. One end of the fixed column 21 is fixedly connected with a connecting platform 22. A clamping platform 23 is fixedly connected to the side wall of the connecting platform 22. A flow sensor 24 is arranged between the clamping platforms 23.

[0027] Specifically, the flow sensor 24 can monitor the water level changes inside and outside the foundation pit in real time, providing data for adjusting the dewatering measures. If debugging and maintenance of the flow sensor 24 are required, the electric push rod two 15 is activated to pull the side plate two 16, causing the side plate one 14 and the side plate two 16 to achieve synchronous relative displacement at the bottom of the fixed table 13. During this process, the push frame 17 at the top of the side plate one 14 and the side plate two 16 will also move synchronously. The movement of the push frame 17 further pulls the connecting rod 18 at its top, causing multiple connecting rods 18 to rotate on the surface of the push table 19 and change their inclination angles. This movement causes the push table 19 to slide on the surface of the fixed table 13, thereby adjusting its position. As the push table 19 moves, the fixing block 20 on the surface of the push table 19, through the connection of the fixing column 21, pushes the connecting table 22 and the clamping table 23. These actions enable the connecting table 22 and the clamping table 23 to effectively fix or disassemble the flow sensor 24, simplifying the maintenance process of the flow sensor 24 and effectively ensuring its normal operation. This reliable fixing and disassembling function ensures that the flow sensor 24 can accurately and stably measure the groundwater level, thereby maintaining the accuracy of the measurement data and the overall stability of the system.

[0028] Working principle: When it is necessary to fix the drainage well 1 and the water pump 25 at its bottom to dewater the foundation pit, the electric push rod one 4 is activated. The electric push rod one 4 pushes the L-shaped rod 5 to make it move vertically up and down. At this time, the rotating plate one 7 inside the L-shaped rod 5 can rotate and change its angle. The rotation of the rotating plate one 7 drives the rotating plate three 9 on its outer wall to rotate inside the rotating plate two 8. At this time, the rotating plate two 8 can rotate inside the rotating table 6. Since the L-shaped plate 10 rotates inside the rotating plate three 9, the rotation process of the rotating plate three 9 will drive the L-shaped plate 10 to rotate. At this time, the pressing column 11 inside the L-shaped plate 10 can be pressed down to effectively fix it to the soil near the foundation pit, ensuring the position stability of the drainage well 1 and the water pump 25, enabling the water pump 25 to pump the groundwater around or inside the foundation pit and discharge it through the drainage pipe 12, ensuring the dryness and stability of the foundation pit during construction, and thus ensuring the smooth progress of the project and construction safety. When debugging and maintaining the flow sensor 24 are required, the electric push rod two 15 is activated. The electric push rod two 15 pulls the side plate two 16, causing the side plate one 14 and the side plate two 16 to synchronously displace relative to each other at the bottom of the fixed table 13. At this time, the push frame 17 at the top of the side plate one 14 and the side plate two 16 can follow and move. The movement of the push frame 17 pulls the connecting rod 18 at its top, causing multiple connecting rods 18 to rotate on the surface of the push table 19 and change their inclination angles. The push table 19 is then pushed to slide on the surface of the fixed table 13. At this time, the fixing block 20 on the surface of the push table 19 can, through the connection of the fixing column 21, push the connecting table 22 and the clamping table 23 to fix or disassemble the flow sensor 24, making its maintenance process convenient and ensuring the normal operation of the flow sensor 24, ensuring its accurate and stable measurement of the groundwater level.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
