The invention provides a continuous construction type movable working platform for a traffic tunnel. Inspection rods and inspection balls at the two ends of the inspection rods are in contact with a wall continuously, cracks of the wall are detected through vibration buckles at the rear ends of the inspection rods and copying devices at the lower ends of the vibration buckles, the construction platform can continuously conduct moving work and uninterruptedly inspect the side wall of the tunnel, and in addition, people can intuitively know about which section of the tunnel is cracked and repairthe cracks in time.

Continuous construction type movable working platform for traffic tunnel

The invention discloses a single-track railway tunnel full cross-section excavation rack. The single-track railway tunnel full cross-section excavation rack includes bottom beams, stand columns, lateral fixing platforms, lateral extensible sleeve pipes, upper part working platforms, middle part working platforms, front part extensible sleeve pipes, middle part turnover working platforms, upper door beams, lower door beams, a crawling ladder, and an escaping rod, wherein the stand columns are mounted on the upper parts of the bottom beams, an door-shaped integral structure is formed by the stand columns, the upper door beams and the lower door beams, the lateral working platforms are mounted on the laterals of the stand columns, the upper part working platforms are mounted on the upper doorbeams, and the middle part working platforms are mounted on the lower door beams; the front extensible sleeve pipes are mounted on the lower door beams and the lateral working platform; the middle part turnover working platforms are mounted inside the stand columns; the crawling ladder is mounted on the rack, and the escaping rod is mounted between the upper part working platform and the ground;and guardrails are mounted on the upper part working platforms, people can be prevented from falling, and safety of working personnel is ensured. The single-track railway tunnel full cross-section excavation rack is reasonable in structure, humanized in design, high in fracture surface applicability, and good in safety protection measure, and the maximum operating space for other processes of tunnel excavation is ensured.

Single-track railway tunnel full cross-section excavation rack and construction method thereof

The invention discloses a use method for an inner die rack for pipe gallery construction. The inner die rack comprises a door frame, movable vertical columns, vertical column lifting support legs, side die plates, a top die plate, a translation driver, a transmission assembly and a motor, wherein the movable vertical columns are located at the two transversal sides of the door frame, and the topsof the movable vertical columns and the outer end of a top door beam of the door frame are slidably installed; the side die plates are installed on the movable vertical columns, the top die plate is installed on the top door beam of the door frame, the movable vertical columns are connected with the door frame at the inner sides of the movable vertical columns through the translation driver, and the movable vertical columns are driven to move through the translation driver, so that driving for the translation movement of the side die plates is realized; and one vertical column lifting supportleg is arranged at the bottom of each movable vertical column, and the height of the whole inner die rack is adjusted through the vertical column lifting support legs. During construction, the inner die rack is capable of automatically adjusting the positions of the side die plates and the own height, so that in-place installation working for the side die plates and the top die plate, and die release working are realized.

Use method for inner die rack for pipe gallery construction

The invention discloses a pipe gallery construction method. The construction method adopts an outer mold trolley, an inner mold formwork and a lifting trolley used for moving the inner mold formwork for construction; through the combined use of the outer mold trolley, the inner mold formwork and the lifting trolley, operations of various stages of the construction can be effectively assisted, theautomatic placement and automatic demolding of an inner side template and an inner top template and an outer template are realized, the labor intensity of workers is effectively reduced, the concretepouring quality is ensured, the pouring and maintenance efficiency is improved and the degree of mechanization of pipe gallery construction is improved; and at the same time, a rain-proof operation function is achieved, the difficulty in manual construction in rainy weather is effectively solved, and the risk of construction in rainy weather is reduced. The structure is simple, the design is reasonable, the function is rich, the movement is convenient, and the pipe gallery construction method is suitable for concrete construction of pipe galleries.
