Description

Technical Field

[0002] Road engineering refers to the entire process of planning, design, construction, maintenance and management work with roads as the object and the engineering entity involved. Like any other type of civil engineering, road engineering has obvious technical, economic and management characteristics. Roadbed compaction (originally: refers to the ratio of the dry density of compacted soil or other road construction materials to the standard maximum dry density, expressed as a percentage.) Roadbed compaction is one of the key indicators for roadbed and pavement construction quality inspection, which characterizes the density condition after on-site compaction. The higher the compaction, the greater the density and the better the overall performance of the material. The compaction detection device is a device used to detect the compaction of the roadbed;

The present invention is connected with the output end of the rotating machine by a clamping interlayer, and the two drilling detection tubes are closed and docked with the sample tube holder, and the sample stripping plate is used to quickly strip the sample after sampling, and then the outer cutting expander is used to expand the diameter on the outside when the drilling detection tube rotates, which has the characteristic of expanding the diameter of the borehole, solves the problem that the diameter of the borehole is the same as the outer diameter of the drill sleeve, which is troublesome when pulling out, and the drill sleeve is easily damaged to affect the test accuracy, and achieves the effect of expanding the diameter of the borehole. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

However, the existing testing device is not convenient to adjust in two states, which reduces the practicality in the later stage. At the same time, after the existing testing tube samples the roadbed, it is not convenient to take out the sampled material as a whole.

[0005] Therefore, in order to solve the above problems, a roadbed compaction detection device for road engineering detection is proposed. Utility Model Content

[0026] Among them: the inspection vehicle 1 is moved to the road section to be inspected, and the horizontal and vertical positions of the inspection tube 8 are adjusted by the first motor 5 and the rotating shaft 6, so that the support plate 4 moves down along the support frame 3, so that the inspection tube 8 passes through the through slot 9 and contacts the roadbed, and the second motor 7 is started to drive the inspection tube 8 to rotate. At the same time, the inspection tube 8 moves down. When sampling is required, the baffle 10 is moved up and fixed, and the roadbed material enters the inspection tube 8.

When only drilling detection is required, the baffle 10 is moved down and fixed, and is fixed to the inside of the slot 12 by the fixed block 11 to fix the baffle 10.

[0027] Embodiment 2

[0028] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below:

[0029] like Figure 2 As shown, as a preferred embodiment; a scale 14 is fixedly installed on the outside of the support frame 3.
