Description

Technical Field

[0001] The utility model belongs to the technical field of engineering detection, and more specifically, particularly relates to a stable pile foundation static load detection device. Background Art

[0002] In construction projects, after the pile foundation construction is completed, in order to ensure the quality of the pile foundation, it is usually necessary to perform a static load test on the pile foundation. When performing the static load test, it is necessary to place a base plate on the upper end surface of the pile foundation and then place a jack on the upper end surface of the base plate. Then, place the counterweight block on the upper end of the jack, and use the jack to lift the counterweight block so that the pile foundation bears the pressure of the counterweight block. Then, the bearing capacity of the pile foundation is detected by the sensor.

[0003] According to the application number: CN201721142119.8, a static load detection device for building pile foundation is disclosed, and its structure includes a hydraulic station, a motor, a pressure gauge, a force sensor, a connecting rod, a connecting line, a data observation storage instrument, a load box, and a hydraulic jack. The force sensor is electrically connected to the front part of the upper end surface of the hydraulic station, and a connecting line is movably connected to the middle of the front end surface of the force sensor, and the other end surface of the connecting line is movably connected to the data observation storage instrument. In the process of detecting the static load capacity of the building pile foundation, the utility model can automatically convert the oil pressure into a load value output, and convert the traditional cable between the sensor and the host into wireless transmission, automatically save data during a power outage, and automatically continue the experiment after a call, so that the user can intuitively detect the test data of the pile foundation load, and store the static load detection data for backup processing, which greatly improves the detection efficiency, thereby saving construction time and money, and effectively improving the reliability of the equipment.

[0004] Based on the above, during the inspection process of the existing pile foundation, when the center of gravity of the counterweight block is offset, the detection device on the pile foundation will cause tilt. When the tilt angle is too large, it is easy to cause the counterweight block to collapse, resulting in economic losses and the collapse of the counterweight block is likely to cause safety accidents, posing a safety hazard.

At this time, the first live wire will be connected to the second live wire, and the alarm will make a sound when the power block is turned on, prompting the staff to adjust the counterweight block in time to prevent the counterweight block from collapsing, thereby improving stability, reducing economic losses and improving safety. Through the setting of the above-mentioned mechanism, the positioning of the bottom plate is achieved, the accuracy of the detection data is guaranteed, and the stability of the static load detection device during the detection process is also detected, thereby improving stability, reducing economic losses and improving safety.
