Hole protection marking device for exploratory hole and special wrench

Abstract

An embodiment of the invention relates to the technical field of geotechnical engineering surveying, in particular to a hole protection marking device for an exploratory hole and a special wrench. Thehole protection marking device includes a cover plate, an inserting pipe, a joint pipe and a centering protection pipe which are arranged from top to bottom in sequence. The top of the inserting pipeis fixedly connected to the bottom surface of the cover plate, and the top surface of the cover plate is provided with two plate disassembling holes; and the top of the joint pipe is detachably connected to the inserting pipe, and the bottom of the joint pipe is fixedly connected to the top of the centering protection pipe. The hole protection marking device can solve the problem that as for an existing marking method, a road is prone to happening safety risks, marks are not prone to disappearing and shifting, and repeated surveying is needed.

Description

technical field

[0001] The present application relates to the technical field of geotechnical engineering investigation, in particular to a hole protection marking device and a special wrench for exploration holes. Background technique

[0002] In urban geotechnical engineering investigation, because there are often dense pipelines around the exploration hole, it is necessary to manually dig a certain depth first to ensure that there is no pipeline at the hole position before backfilling the exploration hole, and then drilling Operation.

[0003] In the prior art, the central position of the exploration hole is generally protected and marked by inserting wooden piles at the opening of the backfill hole or marking the surface of the flattened opening. However, because urban geotechnical engineering survey projects are generally located in On the relatively busy municipal roads in the urban area, the insertion of wooden piles is likely to pose a risk to the safety of the exis...

Examples

Embodiment 1

[0041] Such as figure 1 As shown in the structure, the embodiment of the present application provides an orifice protection marking device 1 for exploration holes, the orifice protection marking device 1 includes a cover plate 11, an intubation tube 12, and a joint pipe 13 arranged in sequence from top to bottom and the centering protection tube 14; during use, the top surface of the cover plate 11 is flush with the ground, and the intubation tube 12, the joint pipe 13 and the centering protection tube 14 below the cover plate 11 are all inserted in the exploration hole for To protect and mark the exploration hole, so that the exploration hole can be easily found when the construction is carried out again;

[0042] The top of the intubation tube 12 is fixedly connected to the bottom surface of the cover plate 11, and the top surface of the cover plate 11 is provided with two unloading holes 111; as figure 1 and figure 2 As shown in the structure, the intubation tube 12 and ...

Embodiment 2

[0053] Such as Figure 4 As shown in the structure, the embodiment of the present application also provides a special wrench 2 for cooperating with the above-mentioned hole protection marking device 1. The special wrench 2 includes a force applying part 21 for holding and a The matching parts 22 at both ends of 21; the matching parts 22 are in one-to-one correspondence with the unloading holes 111 on the cover plate 11 of the opening protection marking device 1 and can be plugged and fitted. The force application part 21 can also be covered with a rubber sleeve 23, which is used to provide a comfortable hand feeling when the user holds it, and can protect the user's hands from injury.

[0054] The distance between the two matching parts 22 of the above-mentioned special wrench 2 needs to be consistent with the distance between the two unloading holes 111 on the cover plate 11 of the above-mentioned orifice protection marking device 1, so that the matching parts 22 can be inser...
