Sampling device for road engineering detection and sampling method thereof

Abstract

The invention relates to the technical field of road detection, in particular to a sampling device for road engineering detection and a sampling method thereof. The sampling device comprises a bottom plate, a cooling box is arranged at the top end of the bottom plate, a water pump is arranged on the inner bottom wall of the cooling box, upper supporting rods are symmetrically arranged at the top end of a connecting plate, a connecting rod is arranged on the output end of a first motor, a lifting buckle is arranged in the lower area of the circumferential outer wall of the connecting rod, a first round hole is formed in the top end of the connecting plate, the circumferential inner wall of the first round hole is slidably sleeved with a shaft sleeve, a connection rod is arranged on the circumferential inner wall of the shaft sleeve, a second motor is arranged at the bottom end of the connection rod, and a connecting shaft is arranged at the output end of the second motor; a rotary drum is arranged in the lower area of the circumferential outer wall of the connecting shaft through a plurality of connecting ribs, a sampling hole is formed in the top end of the bottom plate, and the rotary drum penetrates through the sampling hole and extends to the lower portion of the bottom plate, so that the working efficiency is high, and a thick road surface can be sampled.

Description

technical field [0001] The invention relates to the technical field of road inspection, in particular to a sampling device for road engineering inspection and a sampling method thereof. Background technique [0002] As we all know, road test and detection generally refers to road test and detection. The test items include soil, water, rock, cement, etc. During the construction of municipal roads, any problem in any link will bring serious harm to the quality of the project, and even cause huge damage. Therefore, strict quality control is implemented, and testing and testing of road and bridge structures is also an important means of controlling project quality. [0003] In the process of road inspection, road samples need to be collected. The existing sampling machine is found to be inefficient when used, and because the cross-section of the road surface is thick, the sampling machine cannot remove the sample, which is less practical. In addition, in the existing sampling d...

[0003] In the process of road inspection, road samples need to be collected. The existing sampling machine is found to be inefficient when used, and because the cross-section of the road surface is thick, the sampling machine cannot remove the sample, which is less practical. In addition, in the existing sampling device for road testing, the equipped cooling mechanism cannot detect the usage of cooling water in real time. After the cooling water is completely consumed, the sampling cutting head continues to work at high speed, so that the cutting head cannot be cooled in time and the cause damage
