Building pile foundation detection device

Abstract

The invention discloses a building pile foundation detection device, and belongs to the field of buildings. The building pile foundation detection device comprises a base, the top wall of the base is rotatably connected with evenly-distributed screws, the bottom wall of the base is fixedly connected with evenly-distributed damping devices, the ends, penetrating through the base, of the screws are fixedly connected with first connecting rods, the first connecting rods are rotatably connected with a rotating disc, the screws are in threaded connection with a mounting plate, and the mounting plate is fixedly connected with a hydraulic cylinder through a connecting piece. An extrusion plate is fixedly connected to the top wall of the base, the extrusion plate is fixedly connected with the screws, a positioning device is arranged on the bottom wall of the extrusion plate, a protection device is further fixedly connected to the top wall of the base, and a cleaning device is further fixedly connected to the top wall of the base. The distance between the output end of the hydraulic cylinders and a to-be-detected sample can be adjusted, the measurement result is accurate, manual cleaning after use is not needed, the working intensity of workers is reduced, the working efficiency is improved, the whole equipment is provided with a protection panel, then the situation that the workers are injured by fragments ejected when a pile foundation is broken during pressurization is avoided, and safety is good.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a detection device for construction pile foundations. Background technique [0002] In high-rise buildings, pile foundations are widely used, and when pile foundations are in use, the strength of building pile foundations needs to be tested. Coring method is a detection method that drills core samples from the structure and evaluates the quality of the structure. The damage method has complementary advantages: the method is simple, the structural information is direct and true, and no conversion is required. [0003] After searching, the Chinese patent application number is 201820373830.2, which discloses a pile foundation strength detection device, which includes a support column and a fixed base. A sliding groove is opened at the inner horizontal middle position of the fixed base, and the sliding groove A sliding block is arranged inside, and the top of the sliding block ...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have the following disadvantages: when the device is in use, the distance between the output end and the pile foundation to be tested can only be adjusted through the expansion and contraction of the telescopic hydraulic cylinder. When the expansion and contraction is too long, the detection results will be inaccurate. , will cause the pressure point to shift, which will lead to inaccurate test results, and the fixture will affect the test results due to the clamping of the test device. After the test is completed, it is necessary to manually collect and clean the pile foundation sample fragments after the test , it is a waste of manpower, and the work efficiency is low. When the pressure is applied, the sampling sample will be ejected when it is broken, which poses a safety hazard.
