Description

Technical Field

[0001] The utility model relates to the field of detection, and more specifically, to a pile foundation detection device. Background Art

[0002] Pile foundation testing refers to a series of testing work on the bearing capacity and structural integrity of the pile before and after the construction of the pile foundation. Static load test is a common method for pile foundation testing, which is used to test the bearing capacity of the pile. The traditional static load test is to place a bearing plate on the pile foundation, and then place a hydraulic jack on the bearing plate, and then add a counterweight to the hydraulic jack through a sling, and then the hydraulic jack cooperates with the counterweight to pressurize the pile foundation, and then the auxiliary testing instrument calculates the bearing capacity of the pile foundation. After the test is completed, the counterweights need to be lifted off one by one through the sling again. The process is cumbersome, time-consuming and labor-intensive.

[0003] Based on the above, the purpose of the present invention is to provide a pile foundation detection device to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a pile foundation detection device. The utility model drives the driving frame to move upward through the hydraulic pumps arranged on the support frames on both sides, and the driving frame drives the pressure frame to descend through the driving gear, thereby driving the bearing plate to descend and apply pressure to the pile foundation. The fixed module can be placed in the installation frame and separated from the ground during the pressure application process, and there is no need to add counterweights through the slings, making pile foundation detection more convenient.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a pile foundation detection device, including a bearing plate and a detection instrument, a pressure module is arranged on both sides of the bearing plate, the pressure module includes a support frame, a driving frame and a pressure frame are slidably connected to the support frame, the two sides of the bearing plate are respectively fixedly connected to the pressure frames on both sides, a plurality of driving gears are rotatably connected to the support frame, the driving frame and the pressure frame are both provided with racks meshing with the driving gears, a hydraulic pump is arranged on the support frame, the protruding end of the hydraulic pump is fixedly connected to the driving frame, and a fixing module is arranged on the support frame, and the fixing module can fix the support frame on the bottom surface.

[0006] By adopting the above technical solution, when it is necessary to conduct a static load test on the pile foundation, the detection device is moved to the pile foundation that needs to be tested, so that the bearing plate is located directly above the pile foundation, and the two support frames are located on both sides of the pile foundation, and then the brackets are fixed to the bottom surface through the fixing module, and then the hydraulic pumps on both sides are started. The extended end of the hydraulic pump will push the driving frame to rise. In this process, the driving frame will drive the driving gear to rotate through the rack, and the driving gear will drive the pressure frame to descend through the rack on the other side, thereby driving the bearing plate to descend until the bearing plate contacts the pile foundation. Subsequently, vertical downward pressure can be applied to the pile foundation through the above method, and then the bearing capacity of the pile foundation can be calculated in conjunction with the detection instrument. With this arrangement, there is no need to use a sling to add counterweights, making pile foundation detection more convenient.

[0007] The utility model is further configured as follows: the fixing module comprises a mounting frame, a slide frame is slidably connected to the mounting frame, a motor is mounted on the slide frame, a spiral ground nail is fixedly connected to the output shaft of the motor, and a through slot for the spiral ground nail to pass through is provided on the support frame.

[0009] The utility model is further configured as follows: rollers are rotatably connected to both sides of the driving frame, and a through slot two for the rollers to pass through is provided on the supporting frame.

[0010] The utility model is further configured as follows: a plurality of connecting plates are arranged between the supporting frames at both sides, and two ends of the connecting plates are detachably connected to the supporting frames at both sides.

[0011] In summary, the utility model has the following beneficial effects:

[0012] The utility model drives the driving frame to move upward through the hydraulic pumps arranged on the supporting frames on both sides, and the driving frame drives the pressure frame to descend through the driving gear, thereby driving the bearing plate to descend and pressurize the pile foundation. The fixing module can be placed in the pressure process and the mounting frame is separated from the ground. After the detection is completed, the hydraulic pump drives the driving frame to descend. During the descent of the driving frame, the rollers will be driven to descend until the rollers contact the ground. The supporting frame can also be driven to separate from the ground and rise to a certain height. The entry-level setting does not require the addition of counterweights through the slings, and the detection device can also be moved by the rollers, making the pile foundation detection more convenient.
