Axial force meter is a monitoring tool used to measure the axial force of steel supports during stress to evaluate the safety and stability of foundation pit support structures.

[0003] Under normal circumstances, multiple steel supports are spliced ​​in advance, the axial force meter is installed on the fixed end of the steel support, and then the steel support and the axial force meter are installed in the foundation pit by hoisting. A fixing frame for contacting the steel support and the axial force meter is also set in the foundation pit. The fixing frame is used to increase the rigidity of the foundation pit to prevent the foundation pit from sinking or deformation affecting the monitoring results.

[0004] However, the distance used to install the steel support and the axial force gauge in the foundation pit is fixed and cannot be adjusted. After the steel support and the axial force gauge are installed in the foundation pit, external force is applied to the inner wall of the foundation pit. Therefore, the installation length of the steel support and the axial force gauge is greater than the distance used to install the steel support and the axial force gauge in the foundation pit, which will make the installation of the steel support and the axial force gauge too difficult.

[0031] An auxiliary device for facilitating the installation of a steel support and an axial force meter, the auxiliary device is used to assist the steel support and the axial force meter in being installed in a foundation pit. Steel supports are usually used in foundation pit support structures to ensure the stability of the foundation pit and prevent lateral movement of the soil and collapse of the foundation pit wall. The axial force meter is a monitoring tool used to measure the axial force of the steel support during the force-bearing process to evaluate the safety and stability of the foundation pit support structure. The two ends of the steel support form a fixed end and a flexible end respectively, the axial force meter is fixed on the fixed end, and the steel support and the axial force meter are assembled to form a support axial force monitoring structure. The auxiliary device includes: an abutment and a driving member. The abutment is used to contact the support axial force monitoring structure. The driving member is used to drive the abutment to move so that the abutment is close to or away from the inner wall surface of the foundation pit. Among them, two abutments are provided, the support axial force monitoring structure contacts the two abutments, the support axial force monitoring structure is installed between the two abutments, and the two abutments move simultaneously to fix the support axial force monitoring structure. An installation area for installing the support axial force monitoring structure is formed between the two abutments. When the driving member drives the abutment to move closer to the inner wall of the foundation pit, the length of the installation area is greater than the length of the support axial force monitoring structure. At this time, the support axial force monitoring structure can be placed in the installation area. When the driving member drives the abutment to move away from the inner wall of the foundation pit, the length of the installation area matches the length of the support axial force monitoring structure, and the abutment abuts against the support axial force monitoring structure. At this time, the support axial force monitoring structure is fixed in the foundation pit. The driving member simultaneously controls the two abutments to move closer to the support axial force monitoring structure, so there is no need to disassemble the support axial force monitoring structure after assembly, which saves more time during installation.

[0032] In this solution, the abutment member is a plate, the driving member is a hydraulic cylinder, and the output end of the hydraulic cylinder is connected to the abutment member, so that the driving member drives the abutment member to move closer to and away from the inner wall surface of the foundation pit.

[0033] Example 2

[0034] The difference from Example 1 is that the abutment member includes: a first abutment plate and a second abutment plate. The first abutment plate and the second abutment plate are both plate structures, and a driving member is installed between the first abutment plate and the second abutment plate. The first abutment plate contacts the supporting axial force monitoring structure, and the second abutment plate contacts the inner wall surface of the foundation pit.

[0035] Specifically, a plurality of protrusions are formed on the second abutment plate, and the protrusions are a plurality of conical protrusions formed on the second abutment plate. The protrusions and the second abutment plate are integrally formed structures, and when the second abutment plate contacts the inner wall surface of the foundation pit, the protrusions are inserted into the foundation pit. After the protrusions are inserted into the foundation pit, it can effectively ensure that the abutment member can be fixed to the inner wall surface of the foundation pit, and prevent the supporting axial force monitoring structure from sliding down after being fixed in the installation area.

[0036] Example 3

[0037] The difference from Example 2 is that the driving member includes: a plurality of telescopic tubes and a hydraulic power structure. The plurality of telescopic tubes are used to form a telescopic chamber, and the hydraulic power structure is used to inject liquid into the telescopic chamber to expand the telescopic rod, that is, after the telescopic chamber is filled with liquid, and push the second abutment plate to move to the first position or the second position. The first position is the initial position where the telescopic rod is connected to the second abutment plate, that is, the position of the second abutment plate when the telescopic rod is not expanded. The second position is the position when the telescopic rod pushes the second abutment plate until the support axial force monitoring structure is fixed. When the second abutment plate moves to the first position, the length of the installation area is greater than the length of the support axial force monitoring structure. At this time, the support axial force monitoring structure is hoisted between the two abutments, and then when the second abutment plate moves to the second position, the length of the installation area matches the length of the support axial force monitoring structure. At this time, the support axial force monitoring structure has been fixed between the two abutments, that is, the support axial force monitoring structure is fixed inside the foundation pit.

[0038] Specifically, the hydraulic power structure includes: a liquid tank, a liquid pump and a connecting pipeline. The liquid tank is a box structure made of stainless steel, the liquid pump is a hydraulic pump, and the connecting pipeline adopts a rigid tube body. The liquid pump and the connecting pipeline are used to connect the liquid tank with the telescopic chamber, and to transfer the liquid between the liquid tank and the connecting pipeline. The liquid in this embodiment is hydraulic oil. The liquid pump extracts the liquid in the liquid tank and transports it to the telescopic chamber in the telescopic tube through the connecting pipeline, so that the telescopic tube expands, thereby pushing the second abutment plate to move, so that the second abutment plate moves to the second position. During disassembly, the liquid in the telescopic tube is returned to the liquid tank through the connecting pipeline, so that the second abutment plate moves to the first position, and then the supporting axial force monitoring structure is removed.

[0039] Specifically, the liquid tank and the liquid pump are both arranged outside the foundation pit. After the inside of the foundation pit is fixed by the abutment member and the driving member, if the liquid tank and the liquid pump are arranged inside the foundation pit, it may affect the normal construction inside the foundation pit, so they are arranged outside the foundation pit.

[0040] Specifically, the connecting pipeline includes a main pipe body and multiple branch pipe bodies, the branch pipe bodies are used to communicate with the telescopic chamber, and the main pipe body is used to connect the multiple branch pipe bodies with the liquid tank. By setting up multiple branch pipe bodies, the two abutments can move the same distance when pushed by the driving member, which is convenient for controlling the two abutments to move or stop at the same time. When installing the support axial force monitoring structure, both ends of the support axial force monitoring structure can be stressed at the same time, which is conducive to better fixing the support axial force monitoring structure. If only one end of the support axial force monitoring structure is stressed, then when fixing the support axial force monitoring structure, it may cause the support axial force monitoring structure to tilt, which is not conducive to fixation.

[0041] Specifically, a pressure sensor is provided on the first abutment plate, and the pressure sensor is used to monitor the pressure between the support axial force monitoring structure and the first abutment plate, so as to better analyze whether the pressure can fix the support axial force monitoring structure and ensure that multiple abutments and the support axial force monitoring structure are completely fixed.
