Detection method for concrete pouring elevation in underground bored cast-in-place pile hole

Abstract

The invention discloses a detection method for the concrete pouring elevation in an underground bored cast-in-place pile hole. The method comprises the following steps of: 1) installing direct detection equipment, 2) installing signal transmission equipment, 3) placing a reinforcement cage downwards, 4) detecting the concrete pouring elevation, and 5) recovering a vibration analysis device. The detection method has the beneficial effects that by arranging a conductivity detection device and a specific gravity detection device on the reinforcement cage, whether the concrete reaches a preset elevation position can be effectively and accurately detected, meanwhile, a vibration generation device generates vibration, steel bars directly transmit the vibration to the vibration analysis device, and the vibration analysis device carries out analysis and alarm, so that the purpose of accurately controlling the concrete pouring elevation is achieved.

Description

technical field [0001] The invention relates to the technical field of building construction detection engineering, in particular to a method for detecting the pouring level of concrete in an underground bored pile hole. Background technique [0002] At present, the vast majority of commercial buildings have to set up basement floors, and the basement floors generally have one, two or even three floors. For pile foundations, when constructing reinforced concrete, it is necessary to reserve the thickness of the basement layer at the same time, so as to excavate the basement, so how to accurately judge whether the concrete pouring has reached the elevation of the bottom surface of the basement layer is relatively difficult; in the prior art, generally according to construction personnel Judging by experience, pouring concrete to a certain height on the bottom of the basement and then chiseling it out during the construction of the basement will lead to waste of concrete and af...
