Pile bottom karst cave detection working platform

Abstract

The invention relates to a working platform for pile bottom karst cave detection, which comprises a support plate horizontally arranged above the pile hole, a limit assembly is respectively arranged at the four corners of the support plate and an entrance is opened at the middle position of the support plate, and the support plate A bracket is fixed on the upper surface near the entrance, and a horizontal rotating shaft is connected to the bracket. A rope reel, a hand wheel and a positioning disc are fixed on the outside of the rotating shaft, and the edge position of the positioning disc surface is in a circular array. There are multiple positioning holes, and the bracket is provided with a hook that matches the positioning holes. The outside of the rope reel is wrapped with a traction rope. One end of the traction rope is fixed on the rope reel and the other end is connected to the protection component. The bottom of the protection component Probes are installed. The invention has the effects of high safety factor and convenient operation.

Description

technical field [0001] The invention relates to the technical field of pile bottom karst cave detection, in particular to a working platform for pile bottom karst cave detection. Background technique [0002] Since Yunnan, Guizhou and other places in my country are mostly karst landforms, in order to avoid excessive settlement or even collapse of buildings due to the existence of underground karst caves, it is necessary to establish foundation piles as the foundation for construction in such areas. During foundation pile construction, most of the pile holes currently use rotary drilling or percussion drilling, resulting in mud in the pile holes, and the staff cannot personally reach the bottom of the pile for detection, so the detection of karst caves at the bottom of the pile will be introduced equipment. The pile bottom karst cave detection equipment is generally sonar detection. By receiving reflected echoes and analyzing the condition of unfavorable geological bodies at...

Problems solved by technology

[0003] In the prior art, when the staff use the pile bottom karst cave detection equipment to detect the pile bottom, they need to send the probe to the position close to the pile bottom through the traction rope. However, due to the large diameter of the pile hole, the staff stand on the top of the pile hole to carry out the inspection. When operating, the safety factor is low and the operation is inconvenient, so there is an urgent need for a working platform for pile bottom karst cave detection
