When passing through a collapsed inclined shaft, it is usually necessary for personnel to excavate the collapsed body first, and then reinforce the collapsed position before they can enter the main tunnel through the inclined shaft.

Subsequently, the steel ring component is continuously pushed through the hydraulic press according to the previous entry position of the steel ring component. Before being pushed into the collapsed body, adjacent steel ring components are connected by a first fixing bolt and a connecting ring one and a connecting ring two. After connection, the connecting ring one and the connecting ring two are in contact. By inserting the second fixing bolt, the connecting ring one and the connecting ring two are completed to be connected. There are multiple groups of the second fixing bolts, and the multiple groups of the second fixing bolts are annularly distributed in the connecting ring one and the connecting ring two to ensure the stability of the connection between the connecting ring one and the connecting ring two, and to ensure the stable connection between adjacent steel ring components. To ensure the stability of the connection between multiple groups of steel ring components during the process of pushing the steel ring components into the collapsed body, make the pushing of the steel ring components more stable, and avoid problems such as misalignment, offset, and position movement. When multiple groups of steel ring components completely pass through the collapsed body, at this time, the collapsed soil and slag in the steel ring components can be taken out. The inclined shaft blocked by the collapsed body is connected by the steel ring components. The overall technical structure, through the pipe shed steel pipe components, steel ring components, and steel ring connection components, after being erected, can allow personnel and materials, etc. to pass through the steel ring components through the inclined shaft blocked by the collapsed body to enter the main tunnel. Compared with the method of passing through the collapsed body in the background technology, it has a higher passing efficiency and can effectively solve the problem of not being able to quickly pass through the collapsed inclined shaft.

[0024] Multiple groups of pipe shed steel pipe members 01 are provided, and multiple groups of pipe shed steel pipe members 01 are evenly distributed in a ring shape on the top of the collapse body, and multiple groups of pipe shed steel pipe members 01 are located on the top of the steel ring member 02.

[0027] The connection ring one 31 is provided with through holes at positions corresponding to multiple groups of fixing bolts one 33, and the steel ring member 02 is connected to the fixing bolt one 33 through threaded holes.
[0028] Multiple groups of fixing bolts two 34 are provided, and the connection ring two 32 is provided with holes at positions corresponding to multiple groups of fixing bolts two 34, and the connection ring two 32 contacts multiple groups of fixing bolts two 34 through the holes.

[0030] The first connecting ring 31 is connected to the second fixing bolt 34 through the threaded holes.
[0031] Working principle: When it is necessary to pass through a collapsed inclined shaft, at present, it is often necessary for personnel to excavate the collapsed body, and then reinforce the collapsed position before they can enter the main tunnel through the inclined shaft. The current method has the problem of low passing efficiency and cannot allow personnel, materials, etc. to quickly pass through the collapsed inclined shaft in a timely manner. In the corresponding designed pipe shed steel pipe parts 01, steel ring parts 02, and steel ring connection components 03, when personnel, materials, etc. need to quickly pass through the collapsed body from the inclined shaft into the main tunnel, first, multiple groups of pipe shed steel pipe parts 01 are driven into the upper part of the collapsed body in a circular shape, and the external insertion angle of the pipe shed steel pipe parts 01 is inclined at about ten degrees. The pipe shed steel pipe parts 01 will be located at the top of the collapsed body to prevent further collapse objects from falling in the collapsed hole. After inserting the pipe shed steel pipe parts 01, a steel ring part 02 is pushed into the collapsed body by a hydraulic press. Subsequently, the steel ring part 02 is continuously pushed by the hydraulic press according to the entry position of the previous steel ring part 02. Before being pushed into the collapsed body, between adjacent steel ring parts 02, the first fixing bolt 33 is used to connect the first connecting ring 31 and the second connecting ring 32. After connection, the first connecting ring 31 and the second connecting ring 32 are in contact. By connecting the second fixing bolt 34, the connection between the first connecting ring 31 and the second connecting ring 32 is completed. There are multiple groups of the second fixing bolts 34, and the multiple groups of the second fixing bolts 34 are annularly distributed in the first connecting ring 31 and the second connecting ring 32 to ensure the stability of the connection between the first connecting ring 31 and the second connecting ring 32, and to ensure the stable connection between adjacent steel ring parts 02. During the process of pushing multiple groups of steel ring parts 02 into the collapsed body, it ensures the connection stability between multiple groups of steel ring parts 02, makes the pushing of the steel ring parts 02 more stable, and avoids problems such as misalignment, offset, and position movement. When multiple groups of steel ring parts 02 completely pass through the collapsed body, at this time, the collapsed soil and slag in the steel ring parts 02 can be dug out. The inclined shaft blocked by the collapsed body is connected by the steel ring parts 02. The overall technical structure, through the pipe shed steel pipe parts 01, steel ring parts 02, and steel ring connection components 03, after being erected, can allow personnel, materials, etc. to pass through the steel ring parts 02 through the inclined shaft blocked by the collapsed body to enter the main tunnel. Compared with the method of passing through the collapsed body in the background technology, it has a higher passing efficiency and can effectively solve the problem of being unable to quickly pass through the collapsed inclined shaft. This reinforcement structure is mainly used to temporarily erect and reinforce the collapsed position when a landslide occurs in the inclined shaft to ensure that personnel and materials can pass through the collapsed body.
