Problems solved by technology

When encountering a layered and broken rock mass, the disturbance on the lower side may cause the surrounding rock mass to loosen, and the drill hole collapses causing the probe to be stuck
[0004] In this case, it is impossible to rely on stones to fall into the bottom of the hole under the action of gravity, and high-pressure water washing will cause new damage.

Embodiment 1

[0036] A monitoring probe recovery device in an inclined borehole, comprising a main rod 1, one end of the main rod 1 is fixed with a connecting rod 2, and one end of the connecting rod 2 away from the main rod 1 is fixed with a digging head 3, and the digging head 3 is integrated. The design of the punching head 3 is made of durable and durable materials, which can effectively cut the soil and stone body. The designed shape is a long cylindrical shape. The probe and the cable are very fragile, therefore, the designed digging head 3 must only focus on the blockage and cannot contact the probe and the cable;

[0037] The main body of the digging head 3 is composed of a sturdy and wear-resistant hollow metal cylindrical body. The hollow cylindrical body should not only ensure that the cable can pass through the middle smoothly, but also have enough strength to punch the collapsed rock mass at the stuck point;

[0038] The outer diameter of the digging head 3 is strictly controll...

Embodiment 2

[0046] A monitoring probe recovery device in an inclined borehole. On the basis of the first embodiment, the material of the digging head 3 is mainly made of strong and wear-resistant alloy steel. It can be applied to lighter stainless steel as the body material;

[0047] For drilling holes with different diameters, the drilling head 3 can be designed in three types: small, medium and large.

[0048] Further, in order to ensure that the handle 61 can be connected and fixed with the through hole after being received into the through hole, the inner wall of the through hole adjacent to both ends of the handle 61 is arc-shaped, and both ends of the handle 61 are provided with storage grooves. A top block 62 and a limit block 63 are respectively provided in the two storage slots. One ends of the top block 62 and the limit block 63 are respectively telescopically connected to the storage slot, and the other ends of the top block 62 and the limit block 63 are respectively connected to...

Abstract

The invention discloses a recovery device for a monitoring probe in an inclined drill hole, and relates to the technical field of salvage of stuck probes. According to the technical scheme, the hole digging device comprises a main rod, a connecting rod is fixed to one end of the main rod, a hole digging head is fixed to the end, away from the main rod, of the connecting rod, a through groove is formed in the outer surface of the hole digging head, first grooves are formed in the two sides of the main rod, second grooves are formed in the two sides of the connecting rod, and through holes are formed in the first grooves in a penetrating mode; an anti-falling mechanism is arranged in the through hole and adopts a split type structural design, so that the main rod, the connecting rod and the hole digging head are convenient to disassemble and assemble and are light and rapid to use, and the working efficiency is improved; the hole digging head is used for punching the peripheral hole wall of the probe to enlarge the hole diameter, so that the risk of damage caused by direct impact on the probe is reduced; the through groove is formed in the hole digging head, so that when the periphery of the probe is punched, it is guaranteed that the cable can penetrate through the through groove and cannot be cut, and the cable can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of salvaging stuck probes, in particular to a monitoring probe recovery device in an inclined borehole. Background technique [0002] Under normal circumstances, the hole should be tested before the drilling test starts. If the hole can be formed after drilling, it means that the rock mass of the hole wall will not fall off easily. The drilling test items (sound waves or TV video) also have less disturbance to the hole wall, so the probability of collapse during the drilling test is small. Especially for the in-hole test in the vertical downward drilling, the probe is basically centered, and there is no external force disturbance. Or flushing with high pressure water to let the small stones fall can be solved. [0003] However, inclined boreholes are quite different from vertical boreholes. The probe must be moved by an external thruster. The thruster slides along the underside hole wall. Although measures...
