Soil sampling device for highway engineering and sampling method

Abstract

The invention relates to the technical field of highway engineering, and discloses a soil sampling device for highway engineering and a sampling method. The soil sampling device for highway engineering comprises a fixing plate, supporting plates are fixedly mounted on the two sides of the bottom of the fixing plate, and two universal wheels are fixedly mounted at the bottoms of the two supporting plates; a sleeve rod and two threaded rods are rotatably mounted at the top of the fixing plate, a first belt wheel and a second belt wheel are fixedly mounted at the top end of the sleeve rod and the top ends of the two threaded rods correspondingly, the first belt wheel and the two second belt wheels are in transmission connection with the same belt, and a motor and a control panel are fixedly mounted at the top of the fixing plate; and an output shaft of the motor is fixedly connected with the first belt wheel, a control module is arranged in the control panel, and the control module is electrically connected with the motor. The device is reasonable in structural design, relatively high in automation degree, simple and intelligent to operate and convenient for sampling operation, and solves the problems of high labor intensity and time and labor waste due to the need of manually knocking the sampling barrel.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a soil sampling device and a sampling method for road engineering. Background technique [0002] Highway engineering refers to the investigation, measurement, design, construction, maintenance and management of highway structures. Highway engineering structures include roadbeds, road surfaces, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. In highway engineering, soil sampling is an important task, and soil samplers are often used in the process of sampling soil. [0003] Existing commonly used sampling devices such as CN210863216U and CN212159137U generally need to beat the drill pipe with the help of tools to make the sampling cylinder enter the deep soil layer, but the material requiremen...

Problems solved by technology

[0003] Existing commonly used sampling devices such as CN210863216U and CN212159137U generally need to beat the drill pipe with the help of tools to make the sampling cylinder enter the deep soil layer, but the material requirements for the drill pipe are very high, and the difficulty of taking out the sampling pipe increases with the increase of the sampling depth However, sampling is time-consuming and labor-intensive, and the soil in the sampling cylinder needs to be knocked down by manpower or external tools after the soil is taken. The operation is cumbersome, inconvenient to use, and reduces the work efficiency of the soil. Soil sampling device and sampling method are used to solve the above problems
