Embodiment Construction
[0009] The invention provides a steel plate-concrete composite lining that can be applied to the construction of new tunnels with high requirements on stress and waterproof and the reinforcement of existing structures. It is a steel plate-concrete composite lining that combines support and waterproofing. The partial section is as follows: figure 1 shown. On one side of the steel plate 2 where concrete is poured, the shear connector pegs 4 should be welded. On this side of the steel plate 2, the steel mesh 5 connected and formed by double-hook tension bars 3 should be bound, and the sprayed concrete should be sprayed through the shear connector pegs 4. 1 Combined with each part to form an integral lining.
[0010] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0011] The basic components of steel plate-concrete composite lining are steel plate 2, shear connector stud 4, steel mesh 5 and shotcr...
