A detection method for concrete pouring elevation in underground bored piles

Abstract

The invention discloses a method for detecting the concrete pouring elevation in the hole of an underground bored cast-in-place pile, comprising the following steps: 1) installation of direct detection equipment; 2) installation of signal transmission equipment: 3) lowering of the reinforcement cage: 4) Detection of concrete pouring elevation: 5) Recycling of vibration analysis device; the beneficial effect of the present invention is: by setting the conductivity detection device and the specific gravity detection device on the steel cage, it can effectively and accurately detect whether the concrete has reached the predetermined elevation position, and at the same time The vibration is generated by the vibration generating device, and the vibration is directly transmitted to the vibration analysis device by the steel bar, and the vibration analysis device analyzes and alarms, so as to achieve the purpose of accurately controlling the concrete pouring level.

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...
