A highway engineering detection drilling method

Abstract

The invention discloses a highway engineering detection drilling method, which relates to the technical field of highway drilling, and includes drilling preparation, drilling, soil collection, cleaning and collection pre-preparation, and soil removal and cleaning. The soil removal and cleaning are carried out by making a motor rotate in the reverse direction, driving a spiral rod to rotate in the reverse direction, and transporting the soil in a collecting tube out. At the same time, a water spray row sprays water to clean the surface of the drill tube. Since a guide column is in a guide groove, the rotation of the drill tube can further drive a cleaning block to move downward on the surface of the drill tube. After moving to the lowermost end face, the electric push rod is restored to its original state, so that the cleaning block is restored under the action of a spring disk, thereby solving the problem that a large amount of soil will be squeezed inside the drill tube, and the surface of the soil will be connected to the inner wall of the drill tube, which will make it difficult to remove the soil later.

Description

Technical Field

[0001] The invention relates to the technical field of highway drilling, in particular to a highway engineering detection drilling method. Background Art

[0002] Highway engineering is an indispensable material foundation for the survival and development of cities. Before the construction of highway engineering that connects to roads outside the city and bears external traffic, it is necessary to drill holes and take samples of the soil in advance to facilitate subsequent soil testing and other treatments. At the same time, in the inspection of highway engineering, in order to ensure the quality of the road, it is necessary to conduct relevant inspections on the road surface after the road is completed.

[0003] During the construction of the highway roadbed, the roadbed needs to be compacted to increase the stress level of the roadbed. The compacted roadbed needs to be tested for its compaction. The testing device drills holes inside the roadbed to sample the soil inside the roadbed, and then fills the holes with sand to calculate the density of the roadbed. Pavement thickness testing is an important task. It can be used to evaluate the structural condition of the road and determine whether it needs to be repaired or repaved. A drilling device is needed during the testing process, such as a drilling device and a drilling method for highway engineering testing disclosed in Chinese patent CN117722126B. The drilling device can reduce the amount of dust adhering to the outside of the drill bit, contact the ground through the arc plate, the arc plate gradually opens, the disc moves with the expansion of the arc plate, the disc scratches the dust, the gear plate pushes the dust outward, the middle bar and the disc move with the displacement of the pressure seat, and the insertion rod gradually cuts the dust, thereby ensuring that the equipment has the effect of reducing the impact of dust and improving the surrounding cleanliness.

[0004] Therefore, a drill bit barrel is usually used to drill holes on the road surface. During the drilling process, a large amount of soil will be squeezed inside the drill bit barrel, and the surface of the soil will be connected to the inner wall of the drill bit barrel, which will make it difficult to remove the soil later, resulting in residual soil inside the drill bit barrel, affecting the next drilling measurement. Summary of the invention

During the rotation of the drill tube 10, the spiral rod 38 in the collection tube 14 is also rotated to collect the soil in the borehole, and the rotating device 41 is started to rotate the threaded rod 5, so as to further move the drilling box 1 and the drill tube 10 downward.

[0045] After the drill tube 10 reaches a suitable depth, the motor 15 and the rotating device 41 are turned off, and then the rotating device 41 is rotated in the reverse direction to lift the drill tube 10 out of the borehole;

[0046] After the drill tube 10 is lifted out of the borehole, the electric push rod 36 is started to operate and the guide column 39 is moved into the guide groove 8;

[0047] Finally, the motor 15 is rotated in the opposite direction, driving the screw rod 38 to rotate in the opposite direction to transport the soil in the collecting tube 14 out. At the same time, the water spray row 23 sprays water to clean the surface of the drill tube 10. Since the guide column 39 is in the guide groove 8, the rotation of the drill tube 10 can further drive the cleaning block 37 to move downward on the surface of the drill tube 10. When it moves to the lowermost end surface, the electric push rod 36 is restored to its original state, thereby allowing the cleaning block 37 to restore under the action of the spring disk 34.

The rotation of the motor 15 further drives the rotating rod 17 to rotate. The rotation of the rotating rod 17 further drives the gear ring 12 to rotate. The rotation of the gear ring 12 drives the rotating disk 11 to rotate, and drives the rotating disk 2 13 to rotate in the opposite direction. The rotation of the rotating disk 11 causes the collecting barrel 14 to rotate, and at the same time drives the spiral rod 38 therein to rotate, so as to collect the soil in the borehole. The rotating disk 2 13 rotates, driving the drill barrel 10 to rotate, and drilling holes on the road surface.

[0052] The setting of the drilling collection component drives the drill barrel 10 to rotate, drills holes on the surface of the road, and at the same time makes the collecting barrel 14 and the spiral rod 38 inside the drill barrel 10 rotate in the opposite direction, further collecting the soil inside the drill barrel 10, thereby solving the problem that the surface of the soil is connected to the inner wall of the drill barrel 10 and it is not easy to remove the soil.
