Building pile foundation pit deep pneumatic type inner diameter detection tool

Abstract

The invention discloses a building pile foundation pit deep pneumatic type inner diameter detection tool, which comprises a pile foundation pit, a motor crawler belt assembly, a motor body and an airguide pipe, and a fixed plate strip is arranged at the top edge of the pile foundation pit, a first wind-up roll is rotatably mounted at the top of the left side of the fixed plate strip, and a screwrod is mounted in the fixed plate strip through a bearing; and the outer wall of the left side end of the lead screw is sleeved with a motor crawler belt assembly, a sliding groove is formed in the connecting position of the plate fixing strip and the lead screw, the outer wall of the lead screw is sleeved with a sliding sleeve, the motor body is fixed to the plate fixing strip, and the end of anoutput shaft of the motor body is fixedly connected with the middle shaft end of the first winding roller. The building pile foundation pit deep pneumatic type inner diameter detection tool is small and exquisite in overall size, convenient to carry, transfer and store and convenient and rapid to use, can perform rapid and accurate numerical detection and measurement on different positions and different angles of the deep part in the foundation pit, and facilitates accurate obtaining of the inner diameter.

Description

technical field [0001] The invention relates to the technical field related to building detection, in particular to a pneumatic inner diameter detection tool deep in a foundation pit of a building pile foundation. Background technique [0002] During the construction of houses, in order to improve the stability and strength of the house construction and prevent the inclination and collapse caused by the shaking and instability of the house caused by complex conditions such as external force loads and vibrations, it is necessary to excavate the pile foundation before the foundation construction. The piling operation enables the overall lateral shear force of the house to be greatly borne by the foundation and the pile foundation. However, for pile foundation buildings, it is necessary to manually use detection tools to detect the depth and aperture of the pile foundation before piling to prevent Due to construction efficiency and operational problems, errors in hole diameter ...

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
