Description

Technical Field

[0001] This utility model belongs to the field of pile foundation engineering technology, and in particular relates to a displacement measuring device for large-diameter pile foundations. Background Technology

[0002] Soft soil foundations in coastal areas have high natural water content and low bearing capacity, making them prone to sliding under load. Therefore, they are unsuitable for direct construction. In actual construction, vacuum preloading is typically used to improve the strength of soft soil foundations. Appropriate simulation experiments are required before construction.

[0003] In experiments, displacement measuring instruments are usually assisted by brackets made of welded angle iron. Angle iron is prone to corrosion on soft soil foundations, has a short service life, and requires anti-corrosion and anti-rust treatment with paint, which wastes a lot of manpower and resources. Moreover, it is difficult to adjust or disassemble after welding and installation, and can only be adjusted by cutting. It lacks systematic consideration and has low measurement efficiency. Therefore, how to design a large-diameter pile foundation displacement measuring device that has good versatility and improves measurement efficiency is a technical problem that experimental personnel urgently need to solve. Utility Model Content

[0004] To address the technical problem mentioned in the background art that angle iron supports are difficult to adjust or disassemble after welding and installation, can only be adjusted by cutting, lack systematic consideration, and have low measurement efficiency, a large-diameter pile foundation displacement measuring device is provided to solve the above problems.

[0005] To achieve the above objectives, the specific technical solution of the large-diameter pile foundation displacement measuring device of this utility model is as follows:

[0006] A displacement measuring device for large-diameter pile foundations includes a prefabricated support and a displacement measuring instrument. The prefabricated support includes:

[0007] The system includes a vertical support rod and a horizontal support frame. The horizontal support frame is vertically slidably mounted on the vertical support rod. A vertical limiting device is installed on the vertical support rod. The vertical limiting device is located below the horizontal support frame and is used to support the vertical support rod. A crossbeam is detachably installed inside the horizontal support frame. A displacement measuring device is detachably installed on one side of the crossbeam.

[0008] Furthermore, the vertical support rod is a fully threaded rod, and the vertical limiting components are two support nuts. Both support nuts are threaded into the fully threaded rod. The horizontal support frame has a sleeve hole corresponding to the position of the vertical support rod. The size of the sleeve hole is smaller than that of the support nut. The horizontal support frame passes through the sleeve hole and is inserted into the fully threaded rod. The two support nuts are located above and below the horizontal support frame, respectively, and both are used to abut against the horizontal support frame.

[0009] Furthermore, liquid levels are installed on both sides of the horizontal support frame.

[0010] Furthermore, the prefabricated bracket also includes a first right-angle connector, and the horizontal support frame, the first right-angle connector, and the crossbeam are detachably connected to each other by means of threaded connection.

[0011] Furthermore, the horizontal support frame includes two parallel horizontal support channel steels, several horizontal connecting channel steels, and several second right-angle connectors. The horizontal support channel steels, horizontal connecting channel steels, and second right-angle connectors are detachably connected to each other by means of threaded connection.

[0012] Furthermore, a caster wheel is fixedly installed at the bottom of the vertical support rod, and the caster wheel has a brake.

[0013] The large-diameter pile foundation displacement measuring device of this utility model has the following advantages: This utility model adopts an assembled bracket formed by combining vertical support rods, horizontal support frames, and crossbeams to achieve rapid assembly and disassembly of the bracket. The size of the assembled bracket (including vertical height and horizontal length and width) can be freely adjusted according to the size of the simulation pool to adapt to different experimental sites, improving the flexibility and versatility of the measuring device. Furthermore, the design of universal wheels allows the bracket to move and brake flexibly, facilitating the movement of the displacement measuring device to a position on the same straight line as the pile foundation by the crossbeam. At the same time, the flexible assembly and disassembly of the crossbeam allows the displacement measuring device to be accurately placed above the experimental pile foundation. Compared with traditional angle iron bracket support, this shortens the experimental time and improves the experimental accuracy. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0019] The following is a reference to the appendix. Figure 1 To be continued Figure 2 This invention describes a large-diameter pile foundation displacement measuring device.

[0020] like Figure 1 and Figure 2 As shown, the large-diameter pile foundation displacement measuring device of this utility model includes an assembled bracket and a displacement measuring device 1. The assembled bracket includes a vertical support rod and a horizontal support frame 3. The horizontal support frame 3 is vertically slidably installed on the vertical support rod. A vertical limiting component is provided on the vertical support rod. The vertical limiting component is located below the horizontal support frame 3 and is used to support the vertical support rod. A crossbeam 5 is detachably installed inside the horizontal support frame 3. The displacement measuring device 1 is detachably installed on one side of the crossbeam 5. The vertical support rod supports the horizontal support frame 3 through the vertical limiting component, so that the horizontal support frame 3 can be located above the experimental pile foundation. The crossbeam 5 can be flexibly disassembled and installed at any position inside the horizontal support frame 3. By flexibly disassembling and assembling the crossbeam 5 on the horizontal support frame 3, it can drive the displacement measuring device 1 to accurately fall directly above the experimental pile foundation, thereby improving the experimental accuracy and efficiency.

[0021] It should be noted that the displacement measuring instrument 1 is a device used to measure the displacement or deformation of an object. It is commonly used in experiments and monitoring in fields such as engineering, construction, and geology to help researchers or engineers understand the deformation of a structure and assess its stability and safety. It can be measured using a commercially available displacement measuring instrument 1, which is common knowledge in the art and will not be elaborated here.

[0022] Preferably, the vertical support rod is a fully threaded screw 2, and the vertical limiting components are two support nuts 4, both of which are threaded into the fully threaded screw 2. The horizontal support frame 3 has a sleeve hole corresponding to the position of the vertical support rod. The size of the sleeve hole is smaller than that of the support nut 4. The horizontal support frame 3 passes through the sleeve hole and is inserted into the fully threaded screw 2. The two support nuts 4 are located above and below the horizontal support frame 3, respectively, and both are used to abut against the horizontal support frame 3. Under the threaded engagement of the support nuts 4 and the fully threaded screw 2, the height of the horizontal support frame 3 can be precisely controlled by adjusting the position of the support nuts 4, thereby completing the height adjustment of the assembled bracket. Furthermore, by clamping and tightening the horizontal support frame 3 with the two support nuts 4, the horizontal support frame 3 can be fastened to the fully threaded screw 2, improving the stability of the assembled bracket. The structure is simple and practical.

[0023] Furthermore, liquid levels 6 are installed on both sides of the horizontal support frame 3. By installing liquid levels 6 on the horizontal support frame 3, the levelness of the horizontal support frame 3 can be ensured, thereby improving the measurement accuracy.

[0024] Preferably, the prefabricated bracket also includes a first right-angle connector 7. The horizontal support frame 3, the first right-angle connector 7 and the crossbeam 5 are detachably connected to each other by a threaded connection. The detachable connection by the threaded connection facilitates the assembly and disassembly of the prefabricated bracket and is suitable for engineering construction and experimental conditions.

[0025] Preferably, the horizontal support frame 3 includes two parallel horizontal support channel steels 31, several horizontal connecting channel steels 32, and several second right-angle connectors 33. The horizontal support channel steels 31, horizontal connecting channel steels 32, and second right-angle connectors 33 are detachably connected to each other by threaded connection. The detachable connection by threaded connection facilitates the assembly and disassembly of the prefabricated frame and is suitable for engineering construction and experimental conditions.

[0026] It should be noted that in actual engineering experiments, the crossbeam 5 can also be any horizontal connecting channel steel 32, or the displacement measuring device 1 can be installed on one side of any horizontal connecting channel steel 32 to measure the pile foundation displacement. The staff can make flexible adjustments according to the actual situation.

[0027] Preferably, a caster wheel 8 is fixedly installed at the bottom of the vertical support rod. The caster wheel 8 has a brake. By installing the caster wheel 8 at the bottom of the vertical support rod, it is easy to move and adjust the position of the support, and the brake ensures the stability of the support during measurement.

[0028] The working principle of this utility model of large-diameter pile foundation displacement measuring device is as follows: First, according to the size of the experimental simulation pool, a horizontal support frame 3 of corresponding size is adopted, namely, a horizontal support channel steel 31 of corresponding size, a corresponding number of horizontal connecting channel steels 32 and a second right-angle connecting piece 33. The height of the horizontal support frame 3 is adjusted by rotating the adjustment support nut 4. Then, the assembled bracket is moved to a position close to the experimental device by moving the universal wheel 8, and the displacement measuring instrument 1 is aligned with the experimental pile foundation. Then, the brake of the universal wheel 8 is activated. Next, the crossbeam 5 is disassembled and assembled, so that the crossbeam 5 drives the displacement measuring instrument to move directly above the experimental pile foundation to measure the displacement of the experimental pile foundation.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
