This invention relates to a prefabricated self-forming arch secondary lining structure for tunnels and its construction method. Existing secondary lining structure construction suffers from problems such as high labor intensity, long construction period, and low level of mechanization. The secondary lining structure of this invention includes an invert arch, precast concrete blocks, and hollow steel structural blocks, all equipped with circumferential tensioning ducts. Tensioning ropes are inserted into the tensioning ducts, and under the traction of the tensioning ropes, the invert arch, precast concrete blocks, and hollow steel structural blocks circumferentially form the secondary lining structure. The hollow steel structural blocks are located at the top, the precast concrete blocks on both sides, and the invert arch at the bottom. This invention adopts a prefabricated construction method, allowing for factory-made precast concrete blocks and hollow steel structural blocks, resulting in more controllable quality and a high level of mechanization. During assembly, tensioning is performed after tensioning ropes are inserted into the precast concrete blocks and hollow steel structural blocks, causing the various components to form a circumferential arch under tension, significantly improving construction speed.

This application provides a multi-stage external telescopic hydraulic cylinder, relating to the field of hydraulic cylinder technology. It includes two cylinders, C1 and C2, arranged in parallel. A bracket is fixed to the body of C2, and a circular shaft is rotatably connected to the bracket. A roller is rotatably sleeved on the outer side of the circular shaft. A guide rail is welded and fixed to the outer wall of C1 along its length. The roller is located inside the guide rail. The top of the roller is for rolling contact with the guide rail, and the bottom of the roller is for rolling contact with the outer wall of C1. A gap is left between the roller and the guide rail and between the cylinders. The roller does not simultaneously contact the guide rail and C1. This application uses the roller and guide rail to form a guiding structure. The roller and connecting block jointly bear the radial force, reducing the stress on the arm shell and improving the overall structural strength. The guiding structure uses rolling friction, resulting in low resistance and minimal wear, and allows for easy adjustment of the roller spacing to accommodate wear. The guiding structure is compact, fully utilizing the gap between C1 and C2 without affecting the layout of other pipelines.

The device includes a steel wire rope, boundary warning components, a safety belt, and an alarm. At least two boundary warning components are configured, detachably and spaced apart from each other, to divide the steel wire rope between the two boundary warning components into a working area and the steel wire rope outside the two boundary warning components into a non-working area. The safety belt has a first attachment end for attaching to the working area of ​​the steel wire rope. The alarm is located at the first attachment end of the safety belt and is used to issue a warning signal when the first attachment end comes into contact with any boundary warning component, or when the distance between the first attachment end and any boundary warning component is less than a preset distance threshold. This invention features high safety and requires no damage to the GIS room.
