A kind of pneumatic inner diameter detection tool in the depth of building pile foundation pit

Abstract

The invention discloses a pneumatic inner diameter detection tool in the depth of a building pile foundation pit, comprising a pile foundation pit, a motor crawler track assembly, a motor body and an air guide pipe. The top of the left side of the fixing strip is rotatably installed with a first winding roller, the inner bearing of the fixing strip is installed with a screw rod, and the outer wall of the left end of the screw rod is sleeved with a motor crawler assembly. The connection with the screw rod is provided with a chute, and the outer wall of the screw rod is sleeved with a sliding sleeve, the motor body is fixed on the fixing strip, and the output shaft end of the motor body is in the middle of the first winding roller. Shaft end fixed connection. The pneumatic inner diameter detection tool in the depth of the foundation pit of the building pile has a small overall size, is easy to carry, transport and store, and is convenient and quick to use. The exact size of the inner diameter is obtained.

Description

technical field [0001] The invention relates to the related technical field of building detection, in particular to a pneumatic inner diameter detection tool in the depth of a building pile foundation pit. Background technique [0002] During the construction of the house, in order to improve the stability and strength of the house construction and prevent the problems of tilting and collapse caused by the shaking and instability of the house caused by complex conditions such as external load and vibration, it is necessary to carry out the excavation and collapse of the pile foundation before the foundation construction. The piling operation enables the overall lateral shear force of the house to be greatly carried by the foundation and the pile foundation, while the pile foundation building requires artificial use of detection tools to detect the depth and aperture of the pile foundation between piling to prevent Due to construction efficiency and operation problems, the er...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a kind of pneumatic inner diameter detection tool deep in the foundation pit of construction piles, to solve the above-mentioned background technology. The detection data error will affect the normal progress of the construction work. The overall volume of the device is large for routine transportation and use, and the restrictions are large. The depth change adjustment and azimuth adjustment accuracy are not good. When the inner diameter is detected at the same time, the actual operation is inconvenient. , which requires a great consumption of manual labor, which affects the time-consuming and efficient detection
