Soil sampling device for highway engineering

Abstract

The invention discloses a soil sampling device for highway engineering. The soil sampling device comprises a base, a top plate, hydraulic devices and guide rods; the hydraulic devices are arranged ontwo sides of the top part of the base, and the hydraulic devices are connected to the guide rods through supporting plates; the top plate is installed between the top parts of the guide rods; connecting sleeves are installed at the bottom part of the base, supporting legs are installed at the bottom parts of the connecting sleeves, and universal wheels are installed at the bottom parts of the supporting legs; a motor is installed at the top part of the top plate, and the output end of the motor is connected to a main gear through a coupler; and spiral rotating shafts penetrating through sampling cylinders are connected to the bottom parts of the main gear, a first auxiliary gear and a second auxiliary gear, and the bottom parts of the three sampling cylinders are connected to sampling tubes. According to the soil sampling device, sampling can be performed three groups at the same time, so that the sampling efficiency is high, and the continuity of sampling is improved; the universal wheels are installed at the bottom part of the device, so that the sampling device is convenient to move; and spring structures are connected between the connecting sleeves and the supporting legs, so that the influence of vibration on sampling is reduced.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a soil sampling device for highway engineering. Background technique [0002] Highway engineering refers to survey, measurement, design, construction, maintenance and management of highway structures. Highway engineering structures include: subgrades, 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. The tasks of new construction or reconstruction of highways are determined according to the road network planning. The road construction of a country should comprehensively consider its role and status in combined transportation in combination with railway, waterway, air and other transportation, and formulate a national road system divided into grades according to its political, ...

AI Technical Summary

Problems solved by technology

[0003] In the process of highway engineering construction, it is necessary to carry out sampling inspection on the subgrade surface. The sampling efficiency of the traditional sampling device is low, the soil layer is inconvenient to press into, and continuous sampling cannot be realized. Moreover, the device is inconvenient to move, and the sampling device is easily affected by factors such as vibration during the sampling process. influences
