Detailed Implementation

[0020] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a technical solution: A foundation testing device for municipal building construction quality testing includes a support mechanism 1, a connector 2, and a counter-tension beam mechanism 3; The bottom of the supporting mechanism 1 is provided with a vertically installed hydraulic jack 8, and the bottom of the hydraulic jack 8 is provided with a horizontally installed pressure plate 9. A connector 2 for connecting the anti-tension beam mechanism 3 is installed above the support mechanism 1, and a vertical reinforcement mechanism 5 for reinforcing the anti-tension beam mechanism 3 is also installed above the connector 2. The other end of the anti-pull beam mechanism 3 is equipped with a vertically arranged reaction force fixing member 6, and the bottom of the reaction force fixing member 6 is embedded in the force-applying pile foundation member 7; The reaction fixing component 6 includes a connecting rod 601, and an embedded plate 606 is fixedly connected to the bottom of the connecting rod 601. The bottom of the embedded plate 606 is fixedly connected to the force-applying pile foundation 7. The connecting rod 601 passes through the beam 301 above. A fixing groove 602 is provided above the connecting rod 601. A fixing plate 603 is provided inside the fixing groove 602. A fixing pin 604 for limiting the fixing plate 603 is spirally connected to the outside of the fixing plate 603.

[0021] Support blocks 605 for supporting the anti-pull beam mechanism 3 are fixedly connected to the outer side of each connecting rod 601.

[0022] When conducting static load tests on foundations, multiple primary and secondary beam supports need to be installed around the foundation. A support platform for bearing the counterweight needs to be set up above the jacks, and then the counterweight blocks are hoisted onto the platform to build the counterweight. In actual operation, the built counterweight is often large in size, requiring large hoisting equipment. Moreover, building one stone block at a time is not only inefficient but also poses certain safety hazards. The principle of foundation bearing capacity testing is to use action and reaction forces. The jacks move downward under the reaction force and generate a certain displacement to monitor the foundation bearing capacity. However, this device does not use stones as counterweights. Instead, it uses underground fixed components, reaction fixing components 6 and force-applying pile foundation components 7 to compress the jacks with reaction forces. By eliminating the use of counterweight stones, the size of the testing equipment can be effectively reduced, eliminating the need for large hoisting equipment. Furthermore, this device can be recycled, effectively reducing the cost. This device is smaller in size than traditional foundation bearing capacity testing devices, and its center of gravity is lower, resulting in higher safety performance. Also includes the following: Before assembly, select a suitable foundation area, excavate holes in advance, and pour foundation pits to form a force-applying pile foundation component 7, or excavate holes inside the pile foundation for pouring, and fix the reaction force fixing component 6 inside. When testing the foundation bearing capacity, select a suitable foundation area and level it, then place the bearing plate 9 on the surface, place the hydraulic jack 8 in the center of the bearing plate 9, and then place the support pier (not shown in the figure) on both sides of the hydraulic jack 8. At this time, assemble the device, place the two sides of the support mechanism 1 on the support pier, and then place the connector 2 on the support mechanism 1 and connect them. According to the required foundation bearing capacity, select an appropriate number of anti-pull beam mechanisms 3 and symmetrically install them on the outside of the connector 2. Then install the vertical reinforcement mechanism 5 on the connector 2, and connect the side reinforcement wire 504 to the anti-pull beam mechanism 3. The main body of the device is connected, and then the main body is lifted by the equipment. The other side of the anti-pull beam mechanism 3 is installed on the top of the reaction force fixing component 6 and fixed. There are two fixing methods for the reaction force fixing component 6. When the pile foundation distance is appropriate, holes can be drilled directly inside the original pile foundation and the component can be placed inside. After pouring and fixing, the pile foundation can be used normally when the test is completed. Alternatively, the foundation pit can be excavated again and poured to make a new pile foundation. Since the pile foundation made is often less deep than the normal foundation pit, the top of the force-applying pile foundation component 7 is set in a disc shape to facilitate the subsequent symmetrical placement of counterweight blocks on its surface for weighting purposes. When the reaction fastener 6 is connected, the connecting rod 601 passes through the beam 301 and is inserted into the fixing groove 602 through the fixing plate 603. Then, the fixing pin 604 cooperates with the fixing plate 603 to achieve fixation, so as to prevent the fixing plate 603 from separating from the fixing groove 602. At the same time, a support block 605 is also provided on the outside of the connecting rod 601. The support block 605 is used to support the anti-tension beam mechanism 3 and prevent it from moving down too much. The embedded plate 606 is set inside the force-applying pile foundation 7 and serves as a connection. For foundation settlement monitoring, the DH801-1000 type wire-type displacement sensor (range 1000mm, accuracy up to 0.01mm) is used. It communicates with a computer in real time, allowing for the setting of parameters such as acquisition time and sampling frequency, enabling real-time monitoring of foundation settlement and significantly reducing the burden on monitoring personnel. After data acquisition, further analysis and processing yield reliable data on when foundation settlement occurred and the extent of settlement. It also includes a computer, analyzer, data acquisition unit, pressure sensor, data communication line, etc., all of which are common technical means in the field of detection, so they will not be described in detail here.

The outer side of the connecting plate 201 is provided with evenly distributed mounting grooves 202. The connecting plate 201 is connected to the anti-pull beam mechanism 3 through the mounting grooves 202 and with screws. The top of the connecting plate 201 is provided with a limiting groove 203. The connecting plate 201 is connected to the vertical reinforcement mechanism 5 through the limiting groove 203 and with screws. The bottom of the connecting plate 201 is connected to the support mechanism 1. The anti-tension beam mechanism 3 includes a beam body 301 and a first fixed hanging ring 302. A balancing mechanism 4 for adjusting the balance of the device is fixedly connected to the lower part of the beam body 301. The first fixed hanging rings 302 are evenly distributed on the upper part of the beam body 301. The outer side of the first fixed hanging ring 302 is fixedly connected to the vertical reinforcement mechanism 5. A reaction force fixing member 6 and an inclination detection module 10 for monitoring the level of the device are installed on the side of the beam 301 away from the connector 2.

[0024] The supporting mechanism 1 includes a force-applying plate 101, a support platform 102, and a spiral rod 103. The support platforms 102 are fixedly connected to the outside of the force-applying plate 101 and are evenly distributed. The spiral rod 103 is provided inside the force-applying plate 101. The spiral rod 103 passes through the force-applying plate 101 and is spirally connected to the connecting member 2 at the top.

[0025] The support platform 102 is triangular in shape, and the upper surface of the support platform 102 is raised compared to the upper surface of the force application plate 101.

[0026] The vertical reinforcement mechanism 5 includes a reinforcement column 501, a second fixing ring 502, and a connecting plate 503. The bottom of the reinforcement column 501 is inserted into the limiting groove 203. The outer side of the reinforcement column 501 is fixedly connected to the evenly distributed second fixing rings 502. The outer side of the second fixing rings 502 is connected to a reinforcement wire 504. The other end of the reinforcement wire 504 is fixedly connected to the first fixing ring 302. A connecting plate 503 is fixedly connected to the bottom of the reinforcing column 501, and the connecting plate 503 is fixedly connected to the connecting plate 201 by screws.

[0027] A vertical reinforcement mechanism 5 is provided above the connector 2. The reinforcement column 501 is connected to the anti-pull beam mechanism 3 through the reinforcement steel wire 504. At this time, it can play the purpose of reinforcing the anti-pull beam mechanism 3 when the hydraulic jack 8 is started. The bottom support mechanism 1 is set in an unfolded manner, which can support the bottom of the anti-pull beam mechanism 3. The two work together to ensure the overall stability of the device. Also includes the following: The force-applying plate 101 rests on both sides above the support pier. By rotating the screw rod 103, it is connected to the connecting plate 201. The contact surface area of ​​the force-applying plate 101 and the connecting plate 201 is the same. The support platform 102 is clamped on the outside of the connecting plate 201, and the beam 301 is inserted into the installation groove 202 and connected by screws. The support platform 102 serves to support the beam 301. Then, the reinforcing column 501 is inserted into the limiting groove 203 and fixed by fixing screws. The reinforcing steel wire 504 on the outside of the reinforcing column 501 is fixed to the first fixing ring 302 above the beam 301. At this time, the beam 301 is reinforced to prevent deformation. Depending on the actual situation, different numbers of anti-pull beam mechanisms 3 can be installed on the outside of the connector 2. Different numbers of support platform 102 support mechanisms 1 can be selected to match it, thus expanding the scope of use. Existing detection devices often only remove the hydraulic jack 8 and electronic devices such as detection devices after use. Since hoisting equipment is required when dismantling the counterweight stone blocks, a lot of manpower and resources are consumed. The accumulated counterweight stone blocks are often placed directly in the original area, which poses certain safety hazards when piled up for a long time. This device can be disassembled and recycled to achieve recycling.

[0028] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 6Specifically, the balancing mechanism 4 includes a mounting frame 401, a hydraulic push rod 402, and a push block 403.

The bottom of the push block 403 is fixedly connected to a connecting wire rope 404. The other end of the connecting wire rope 404 is provided with a hanging rope 405.

The bearing platform 702 is fixedly connected to the top of the pile base body 701, and the pile base body 701 and the bearing platform 702 are fixedly connected to the reaction force fixing member 6 inside.

[0030] When the force-applying pile foundation 7 is selected, the force-applying pile foundation 7 is set underground, and the area above the bearing platform 702 is large, which is used to symmetrically place counterweights and can play a good anti-pull purpose. At the same time, the number of anti-pull beam mechanisms 3 can be set according to the actual test situation. When the foundation bearing capacity to be tested is large, the number of anti-pull beam mechanisms 3 can be increased to match it and expand the scope of use. Meanwhile, a balancing mechanism 4 is also provided at the bottom of the anti-tension beam mechanism 3. When the tilt detection module 10 deviates, the balancing mechanism 4 can be activated to adjust it and ensure the stability of the device. Also includes the following: When the tilt detection module 10 detects that the device is tilted, the external control unit controls the hydraulic push rod 402 at the corresponding position to move the push block 403. The push block 403 moves the connecting steel wire rope 404, hanging rope 405 and counterweight 406 below to adjust the overall stability of the device. The bottom of the connecting steel wire rope 404 is connected to the hanging rope 405 through a hook. It adopts a detachable connection method to facilitate disassembly and recycling.
