[0002] A foundation pit is an underground space excavated for the construction of a building's foundation and basement. These spaces are usually excavated for purposes such as laying underground pipelines, installing underground facilities, or expanding basements. During the construction of a foundation pit, concrete needs to be poured into the pit to build the pile foundation cap or seal the bottom of the pit.

[0003] However, existing infill devices often start the infilling process from the middle, which cannot fully and evenly infill the interior. Some areas may not be effectively reinforced, which can reduce the bearing capacity of the foundation and potentially lead to problems such as foundation settlement and deformation.

[0004] Therefore, it is urgent to improve the grouting equipment used in deep foundation pit construction to solve the above-mentioned problems. Utility Model Content

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-5As shown, the grouting device for deep foundation pit construction provided in this embodiment includes a base plate 1, a storage tank 2 installed on the base plate 1, a water pipe 3 connected to the bottom of the storage tank 2, a water pump 4 connected to one side of the water pipe 3, a feed inlet 5 installed on the storage tank 2, a fixing frame 6 installed on the base plate 1, a first screw 7 installed inside the fixing frame 6, a first drive motor 8 connected to the first screw 7 installed on the top of the fixing frame 6, a movable plate 9 installed on the outer wall of the first screw 7, a nozzle 10 installed on one side of the water pipe 3 passing through the movable plate 9, a fixing frame 11 installed at the bottom of the base plate 1, a second screw 12 installed inside the fixing frame 11, a second drive motor 13 connected to the second screw 12 installed on one side of the fixing frame 11, a movable block 14 installed on the outer wall of the second screw 12, a first electric telescopic rod 15 installed on one side of the movable block 14, and a clamp movably installed on one side of the first electric telescopic rod 15 connected to the water pipe 3. Block 16, the clamping block 16 is arc-shaped and fits against the water pipe 3. When the grouting device starts to grout the deep foundation pit, the first drive motor 8 can drive the first screw 7 to rotate. The moving plate 9, which is threaded to the first screw 7, will also rise and fall. At the same time, the nozzle 10, which is connected to the water pipe 3, will also rise and fall. Meanwhile, the second drive motor 13 on the fixed frame 11 drives the second screw 12 to rotate, which will drive the displacement of the moving block 14. The first electric telescopic rod 15 on the moving block 14 and the clamping block 16 can cooperate to allow the nozzle 10 to grout the deep foundation pit fully and evenly, ensuring that the deep foundation pit is effectively reinforced, enhancing the bearing capacity of the foundation, and increasing the cohesion and shear strength of the foundation soil. This helps to reduce the deformation and settlement of the foundation and improve the overall stability of the foundation. In deep foundation pit engineering, the stability of the foundation is directly related to the safety and stability of the project.

[0024] Furthermore, such as Figures 1-5 As shown, a rotating rod 17 is installed inside the storage tank 2, and several stirring rods 18 are installed on the outer wall of the rotating rod 17. A third drive motor 19 connected to the rotating rod 17 is installed on the storage tank 2, and a guide block 20 is installed inside the storage tank 2. The third drive motor 19 drives the rotating rod 17 to rotate, and at the same time, the stirring rods 18 also stir the concrete in the storage tank 2. The concrete that is constantly being stirred can delay the curing time and increase the sustainable service life. A rubber pad 29 is installed at the bottom of the support column 23. The rubber pad 29 can reduce the friction of the support column 23 when it is not needed, thereby reducing the degree of wear and extending the service life. A counterweight 30 is installed on the outer wall of the water pipe 3, and several lights 31 are installed on the counterweight 30. The lights 31 can prevent the difficulty in grasping the pouring situation during the pouring process due to the deep foundation pit, which facilitates the stable construction.

[0025] Furthermore, such as Figures 1-5As shown, multiple casters 21 are symmetrically installed on the bottom of the base plate 1, and multiple fixed boxes 22 are symmetrically installed on the base plate 1. A support column 23 is installed inside the fixed box 22. The support column 23 extends downward through the base plate 1. A pulley 24 is installed on the support column 23. A fixing ring 25 is installed on the support column 23. A spring 26 connected to the fixed box 22 is installed on the fixing ring 25. A second electric telescopic rod 27 is installed on the inner wall of the fixed box 22. A push block 28 is installed on one side of the second electric telescopic rod 27. By pushing the push block 28 which is in contact with the pulley 24 using the second electric telescopic rod 27, the support column 23 can be moved downward, supporting the casters 21 to lift off the ground. This prevents the casters 21 from slipping due to gravity or other factors, which could cause the infusion device to lose control and affect the overall infusion process.

[0026] like Figures 1-5 As shown, the principle of the grouting device for deep foundation pit construction provided in this embodiment is as follows: When the grouting device starts to grout the deep foundation pit, the first drive motor 8 can drive the first screw 7 to rotate, and the moving plate 9 threadedly connected to the first screw 7 will also rise and fall. At the same time, the nozzle 10 connected to the water pipe 3 will also rise and fall. Meanwhile, the second drive motor 13 on the fixed frame 11 drives the second screw 12 to rotate, which will drive the displacement of the moving block 14. The first electric telescopic rod 15 and the clamping block 16 on the moving block 14 can cooperate to allow the nozzle 10 to grout the deep foundation pit fully and evenly, ensuring that the deep foundation pit is effectively reinforced, enhancing the bearing capacity of the foundation, and enhancing the cohesion and shear strength of the foundation soil. This helps to reduce the deformation and settlement of the foundation and improve the overall stability of the foundation. In deep foundation pit engineering, the stability of the foundation is directly related to the safety and stability of the project.
