Description

technical field

In the process of geological disaster prevention and control, it is often necessary to cast piles in boreholes. According to different geological conditions and buildings, the diameter of bored piles can be tens of centimeters to two or three meters, and the depth can be from ten meters to several meters. It varies from ten meters to ten meters. During the construction process, the steel cage is first drilled and then the steel cage is put into the pile hole, and finally the concrete is poured. The mud will precipitate to form sediment, and the sediment at the bottom of the hole will affect the bearing capacity of the bored pile and the control and estimation of settlement, resulting in deviation of the size of the hole. Therefore, a hole detector is required for hole inspection, especially in geological construction locations. Located in the deep water area, the main pier cap needs to be heightened and the bottom-sealing concrete needs to be thickened, and there are multiple variable-section bored end-bearing piles under the cap, and the diameter of the pile foundation from the bottom of the cap to the rock surface can vary from 250cm to 350cm Amplitude.

However, the cost of such equipment is relatively high and it is difficult to implement on a large scale. At present, the diameter of the detection hole is often set to The required frame with the same diameter is put down into the aperture. If it cannot be lowered during the placement process, it is judged that the aperture is smaller than the required aperture, and the aperture needs to be widened, which requires a very large frame to be placed in the aperture, not only It is relatively bulky, and the radius of the frame cannot be adjusted according to the requirements, which causes great inconvenience in the construction process.
