Problems solved by technology

In the prior art, trimming is mainly done manually, and the flatness of the bottom of the detection hole and the arc of the side of the detection hole cannot be guaranteed, and the requirements for operators are relatively high.
And it is often necessary to dig out a lot of detection holes to have one that is suitable for detection, and the efficiency is particularly low.

Embodiment Construction

[0063] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0064] Please refer to Figure 1 to Figure 8 , the present invention proposes an auxiliary hole-digging device for detecting the solidity of the roadbed by sand filling method, which includes a base plate 1 , a bracket 2 , a first transmission assembly 3 , a second transmission assembly 4 and a third transmission assembly 5 .

[0065] Wherein, the base plate 1 is used to contain the excavated soil, and the excavating cylinder 43 is limited to ensure that the diameter of the trimmed detection hole is equal to that of the circular hole 11 on the base plate 1 . The bracket 2 is used to carry the entire auxiliary hole digging device. The first transmission assembly 3 is used to adjust the position of the excavator 43 in the circumferential direction, and the second transmission assembly 4 is use...

Abstract

The invention discloses an auxiliary hole digging device for detecting roadbed solidity based on a sand filling method. The device comprises a base plate, a bracket, a first transmission assembly, a second transmission assembly and a third transmission assembly; a round hole is formed in the base plate, and a baffle plate is arranged on the edge of the base plate; the bracket comprises a pluralityof supporting rods, a first supporting plate and a second supporting plate; the supporting rods are successively and fixedly connected with the first supporting plate and the second supporting platefrom top to bottom and uniformly distributed in the circumferential direction of the second supporting plate; grooves are formed in the lower ends of the supporting rods, and the grooves are used forcooperating with the edge or top angle of the base plate; a stepped hole is formed in the second supporting rod, and the diameter of the stepped hole is reduced from top to bottom; a blind hole is further formed in the second supporting plate, the center line of the blind hole is parallel to that of the stepped hole, and the blind hole is communicated with the stepped hole; the device can conveniently correct the side wall and bottom of a detecting hole.

Description

technical field [0001] The invention relates to a hole-digging device, in particular to an auxiliary hole-digging device for detecting the solidity of a roadbed by filling sand. Background technique [0002] The sand filling method is a standard method for testing the degree of subgrade compaction, and it plays a very important role in the quality control of highway engineering. However, the sand filling method still needs to manually excavate the soil layer and dig a pit to carry out the tank sand in actual operation, and the efficiency is low. [0003] In order to ensure the accuracy of measurement, it is necessary to trim the dug detection hole so that the bottom of the detection hole is flat and the side of the detection hole is close to the standard cylindrical surface. In the prior art, trimming is mainly done manually, and the flatness of the bottom of the detection hole and the arc of the side of the detection hole cannot be guaranteed, and the requirements for oper...
