The two ends of the sleeve are provided with a connecting female end and a connecting male end, and the connecting female end and the connecting male end are both provided with connecting holes. There are multiple connecting holes, and the multiple connecting holes are located at the same height. The connecting holes of the connecting female ends on adjacent sleeves can be opposite to the connecting holes of the connecting male ends, which is convenient for rescue personnel to insert the connecting pin shaft into the two opposite connecting holes to fix the adjacent sleeves.

[0004] The above-mentioned technology of connecting the casings to each other is that when installing the connecting pin into the connecting hole, an iron ring with an internal thread is fixed to the connecting female end, and then the connecting pin is screwed from the outside of the vertical casing into the connecting hole aligned with the connecting female end and the connecting male end, and the connecting pin and the iron ring are rotated for threaded connection to achieve mutual connection between the connecting female end and the connecting male end. During the rescue, if the stratum consists of bedrock stratum and water-bearing stratum in the Quaternary stratum, grouting is required to reinforce the stratum during the process of drilling the above-mentioned casing. At this time, part of the casing will be tightly connected to the stratum. After the rescue is completed, the vertical casing cannot be pulled out as a whole because part of the casing is tightly fixed to the stratum. Moreover, because the vertical casing cannot be disassembled from the inside, part of the casing tightly connected to the stratum will be disassembled and pulled out, and the vertical casing cannot be recovered, resulting in waste.

The window casing 11 and the pipe shoe 3 are detachably connected by the connecting assembly 2. The pipe shoe 3 can drill into the formation to achieve the purpose of feeding the vertical casing 1. The conventional casings 12 are detachably connected by the connecting assembly 2. The window casing 11 and the conventional casing 12 are detachably connected by the connecting assembly 2. Both ends of the window casing 11 and the two ends of the conventional casing 12 are provided with a connecting female end 4 and a connecting male end 5. The top of the pipe shoe 3 is set to be a connecting male end 5, and the connecting female end 4 and the connecting male end 5 are both provided with a plurality of connecting holes 6. In the embodiment of the present application, the seat pad 7 is fixedly connected to the inside of the connecting hole 6 by welding. The axes of the connecting holes 6 are perpendicular to the axis of the vertical sleeve 1.

The connecting component 2 can be disassembled inside and outside the vertical sleeve 1. The connecting component 2 is connected to the inside of the connecting holes 6 of the connecting male end 5 and the connecting female end 4 that are aligned with each other. After the connecting component 2 passes through the two mutually opposite connecting holes 6 and the seat pad 7, the purpose of fixing the connecting female end 4 and the connecting male end 5 to each other is achieved.

[0039] When carrying out a rescue, the rescue personnel start the external drive to drive the vertical casing 1 and the pipe shoe 3 to rotate. At this time, the pipe shoe 3 drills into the stratum. The rescue personnel remove the gravel and soil debris inside the vertical casing 1 and the pipe shoe 3 by operating the sand bucket of the rotary drilling rig to build a rescue channel. When installing the vertical casing 1, the rescue personnel plug the connecting female end 4 and the connecting male end 5 into each other, and align the connecting holes 6 one by one. The connecting assembly 2 is connected between the connecting holes 6 from the outside of the vertical casing to achieve the connection between the connecting female end 4 and the connecting male end 5.
