Novel surveying device for geological survey and surveying method

Abstract

The invention discloses a novel surveying device for geological survey and a surveying method, and relates to the technical field of geological survey. The novel surveying device for geological surveycomprises a base; two symmetrical buffer mechanisms are fixedly connected to the bottom surface of the base; a transmission mechanism is fixedly connected to the left side of the upper surface of thebase; a drilling mechanism is in clamped connection in the transmission mechanism; and an extraction mechanism is fixedly connected to the left side of the upper surface of the base. According to thenovel surveying device for geological survey and the surveying method disclosed by the invention, due to arrangement of a first screw ring, under the combined action of a first positive and negativemotor and a transmission chain, a screw cylinder and a drilling block can drill towards the interior of a foundation; due to arrangement of the drilling block, under the action of a second positive and negative motor, a transmission rod and an internal thread path, soil in the foundation can be sampled through the downward rotation motion of the drilling block; due to arrangement of an induced draft fan, an soil sample filled in a filling groove can be rapidly extracted; furthermore, the problem that a soil surveying device needs to drill integrally and repetitively is avoided; and the soil sampling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to a novel surveying equipment and surveying method for geological surveying. Background technique [0002] Geological survey is a geological survey and research work to find out the geological factors affecting engineering buildings. The geological factors required for survey include geological structure, landform, hydrogeological conditions, physical and mechanical properties of soil and rock, natural (physical) geological phenomena and natural building materials, etc. [0003] Sampling for geological survey is the preliminary work for soil identification and providing samples for various indoor tests. Existing geological survey equipment generally adopts the method of drilling soil for deep sampling of sandy soil, but this This method needs to be drilled and pulled out for sampling every time the soil at a specified depth is taken out. When the soil at different depths...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a new surveying equipment and surveying method for geological surveying, which has the advantage of being able to easily take out soil at different depths through one drilling, and solves the problem of existing geological surveying equipment. The problem of repeated drilling when sampling soil at different depths
