Abstract

The invention provides a pile hole rock sample picking device, comprising: a vertical protective tube; a skeleton, including a fixed frame and a movable frame vertically arranged in the vertical protective tube, and both sides of the fixed frame are connected to the vertical protective tube The inner wall of the movable frame is embedded in the fixed frame, and the middle part of the movable frame is pivotally connected to the middle part of the fixed frame; the lock used to lock the movable frame and release the movable frame after bottoming in the pile hole is installed on the fixed frame ; A driving member for pushing on one side of the movable frame to make the movable frame rotate, installed on the fixed frame; To the upper port of the protective sleeve, there are multiple pieces of cover nets, the cover nets are connected between the top of the fixed frame and the top of the movable frame, and the bottom nets are connected between the bottom of the fixed frame and the bottom of the movable frame. The invention solves the problem of inaccurate rock samples collected by the traditional pile-hole fishing rock samples.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a pile hole rock sample fishing device. Background technique [0002] At present, construction projects have high requirements for pile foundation construction quality, and some drawings require that bored piles need to extend into specified rock formations. For example, a project of bored piles requires one meter to enter the middle weathered rock formation as the basis for the final hole. At the same time, the pile length is relatively long (the average elevation is about 70-80m), but because the traditional bored pile construction adopts positive circulation and punching technology , the rock samples taken at the mouth of the casing have too many impurities, resulting in unclear rock samples. At the same time, because the pile length is too long, the rock slag at the bottom of the hole cannot be discharged from the mouth of the casing at the first time, and becau...
