Description

A soil borrowing device for sand filling method

technical field

The utility model relates to the field of soil borrowing devices, in particular to a soil borrowing device of a sand filling method.

Background technique

Subgrade compaction is a key indicator to control the construction quality of subgrade, and directly affects the service life of the road. The sand filling method of digging pit is the most commonly used test method in the testing of roadbed compaction. The mass of the sand in the test pit and the sand bulk density are used to determine the volume of the test pit, and the water content of the filler is determined by the drying method to calculate the measured dry density of the sample.

In actual work, we found that the roadbed has a high degree of compaction after being rolled by the road roller. The commonly used digging method requires the staff to squat on the ground, dig with a shovel, and chisel with a hammer, which is time-consuming and laborious, and requires long-term squatting labor. For the test, the physical burden is heavier for the working staff, although there are also some mechanical devices on the market for digging holes and collecting soil.

However, the existing mechanical devices for digging holes and borrowing soil have the following deficiencies in use:

First, it is inconvenient to control the excavation depth;

Second, due to the lack of a fixing mechanism, displacement is easy to occur when digging holes for soil extraction, which in turn leads to the inclination of the excavated holes, which reduces the efficiency of soil extraction.
