Problems solved by technology

[0002] During the road construction process for many years, the sampling method (sand filling method) for the compactness of the road base and subbase has been using the ancient operation method, that is, manual operation with heavy and simple tools such as hammers, screwdrivers, and flat shovels. The whole process requires a lot of labor (generally 2-3 people), takes a long time (20-30 minutes), the water content of the sample is easy to lose, and it is highly flexible to the soil, the surrounding wall of the sampling pit is not smooth, and the sampling effect is poor. poor accuracy

Abstract

The invention discloses a base layer sampling device for road construction. The base layer sampling device for road construction comprises a roadbed sampling table and a sampling column and a workingmotor. Telescopic supporting legs are separately arranged at four ends of the lower side of the roadbed sampling table, telescopic supporting columns are separately arranged outside the telescopic supporting legs, a reserved hole is formed in the middle of the roadbed sampling table, a fixed shaft sleeve is embedded into the middle of the reserved hole, a forward thread is arranged on the outer side of the sampling column, a rotary shaft of the motor is arranged at the upper part of the working motor, a limiting protecting ring is arranged at the upper part of the rotary shaft of the motor, and a first backward thread matched with the forward thread is arranged outside an electric rotary disc. As the telescopic supporting legs are separately arranged at four ends of the lower side of the roadbed sampling table, the sampling device can be placed according to terrain of road construction. The fixed shaft sleeve is embedded into the middle of the reserved hole, so that the working stability of the sampling column can be enhanced. The first backward thread matched with the forward thread is arranged outside the electric rotary disc and a second backward thread matched with the forwardthread is arranged on the outer side of a manual rotary disc, so that the sampling precision is improved by cooperation of manual and electric operations.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a base sampling device for road construction. Background technique [0002] During the road construction process for many years, the sampling method (sand filling method) for the compactness of the road base and subbase has been using the ancient operation method, that is, it is manually operated with heavy and simple tools such as hammers, screwdrivers, and flat shovels. As far as the whole process is concerned, it requires a lot of labor (generally 2-3 people), takes a long time (20-30 minutes), the water content of the sample is easy to lose, and it is highly flexible to the soil, the surrounding wall of the sampling pit is not smooth, and the sampling effect is poor. Accuracy is poor. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be descr...
