Embodiment 1

[0037] refer to figure 1 The device for quickly solving the problem of compaction digging includes a digging member 1 for digging a roadbed and a sample holding member 2 for collecting soil samples. The setting of the digging member 1 facilitates uniform digging of the roadbed pit, thereby ensuring the consistency of digging means, improving the quality of digging, and then improving the accuracy of detection data, and at the same time shortening the construction time and improving construction efficiency; the setting of the sample holding member 2 facilitates the collection of excavated soil samples , and then it is convenient to weigh the collected soil samples, and at the same time, it is convenient to recycle the collected soil samples and reduce the waste of resources.

[0038] refer to figure 1 with figure 2 The hole-piercing member 1 includes a driving rod 11, a helical blade 12 and a cutter head 13, one end of the driving rod 11 is welded to the cutter head 13, the ...

Embodiment 2

[0043] refer to image 3 with Figure 4 , the difference from Embodiment 1: the baffle plate 3 is slidingly connected with the driving rod 11, and at least one limiter 6 is provided on the side of the baffle plate 3 close to the drive rod 11, and two limiter members 6 are provided in this embodiment , the limiting member 6 is set as a spring pin, and the two limiting members 6 are evenly distributed along the circumferential direction of the baffle plate 3. The drive rod 11 is provided with a plurality of slots 111 for the limiting member 6 to be embedded in, and all the slots 111 are along the The axial distribution of the driving rod 11 is uniform; the baffle plate 3 is slidably connected with the driving rod 11, which is convenient for digging pits of different depths, expanding the application range of the digging device, and improving the practicability of the digging device. The arrangement of the groove 111 facilitates fixing the position of the baffle 3 , thereby redu...

Abstract

The invention discloses a pit digging device for rapidly solving compaction degree, and particularly relates to the technical field of roadbed construction. The device comprises a pit digging component used for digging pits in a roadbed and a sample containing component used for collecting soil samples. The pit digging component comprises a driving rod, a spiral blade and a cutterhead, wherein one end of the driving rod is connected with the cutterhead, the spiral blade is located on the driving rod, and the spiral blade is wound in the axial direction of the driving rod. According to the pit digging device for rapidly solving compaction degree, unified pit digging can be conveniently carried out on the roadbed through the pit digging component, so that the consistency of pit digging means is guaranteed, the pit digging quality is improved, and therefore, the accuracy of detection data is improved; meanwhile, the construction time is shortened, and the construction efficiency is improved; by arranging the sample containing component, the soil sample guided out by the spiral blade can be conveniently collected, so that the collected soil sample can be conveniently weighed, and meanwhile, secondary utilization of the soil sample is facilitated, and waste of resources is reduced.

Description

technical field [0001] The invention relates to the technical field of roadbed construction, in particular to a device for quickly solving compaction degree digging. Background technique [0002] The degree of subgrade compaction refers to the ratio of the dry density of soil or other road construction materials after compaction to the standard maximum dry density, expressed as a percentage. The degree of subgrade compaction is one of the key indicators for the quality inspection of subgrade pavement construction. The higher the degree of compaction, the greater the density, and the better the overall performance of the material. [0003] In related technologies, when testing the compactness of the subgrade, it is necessary to collect various samples for testing. During the sample collection process, the subgrade is manually drilled with a hammer or chisel until a pit of a specified size is dug. [0004] Regarding the above-mentioned related technologies, the inventor belie...
