As shown in fig. 13 and 14, the first truss 10 and the second truss 11 are respectively provided with a coil buckle, and the connecting sleeves 14 are arranged at the mutually connected ends of the first truss 10 and the second truss 11 in a staggered manner, so as to realize the butt connection of the first truss 10 and the second truss 11, thereby forming a butt-bracing assembly.
As shown in fig. 15, the sliding roller 4 includes a roller frame, two rollers are mounted on the roller frame, the sliding roller 4 is supported on the sliding track steel 3 through the two rollers, and the chain block 5 is suspended below the sliding roller 4.
Fig. 1 is a schematic structural view of a two-hole tunnel according to the present invention, and fig. 2 is a schematic structural view of an intermediate wall formwork 2 corresponding to the two-hole tunnel according to the present invention. When the concrete application, at first install lower chamfer template 1 in the suitable position in the tunnel, pour the corresponding position of the upper edge mouth of lower chamfer template 1 with the bottom plate concrete, solved traditional wooden pattern easy loss, can not have enough and rigidity not enough problem many times.
When the side wall formwork 8 is used specifically, the steel frame formwork system is adopted for solving the difficult problem that the traditional wood formwork cannot be turned over, the loss is large, and the wood formwork still occupies long time and other adverse factors. The side wall template 8 has the characteristics that the concrete surface is relatively flat when the side wall is poured, the problems that a wood template system is difficult to disassemble, slurry leaks, a mold runs, a mold is exploded and the like are solved.
When concrete application, can adopt standard truss system according to the tunnel width design of difference to propping the subassembly, according to the side wall height setting in tunnel, the side wall truss supports the quantity that can reduce traditional steel pipe and support to can draw the advantage that can full play dish knot frame will be apart from the grow simultaneously of roof support frame body. The traditional steel pipe fastener full red support adopts the steel pipe and the fastener as a force transmission mechanism, so that the axial stress is difficult to ensure to a great extent, meanwhile, one steel pipe is arranged symmetrically every 400mm in the vertical tunnel direction, one upright rod is arranged every 600mm in the tunnel direction, the operation difficulty of workers is high, however, the counter-bracing component can be arranged one or two times to solve the problem of the traditional bearing capacity, meanwhile, the top end of the truss is designed into a connecting sleeve 14 form, an axis stress system can be perfectly formed, meanwhile, two adjacent pairs of supporting assemblies (formed by butting a first truss 10 and a second truss 11) are connected by a coil buckling frame cross rod to form a lattice column system, so that the bearing capacity of the material is greatly improved and utilized, the bearing capacity of the traditional steel pipe full red supporting single pair supporting steel pipe is only 1.2t, and 30t of single-group combined truss supporting can save nearly 60% of the material.
Go up chamfer template 9 and banned traditional plank sheathing, solved safe quality problems such as chamfer template easily runs the mould, explodes the mould, leaks thick liquid. Because the upper chamfer template 9 is a steel frame wood mould with higher integral rigidity, measures such as steel pipe buckling frame reinforcement and the like are not needed.
The triangular support 6, the sliding rail steel 3 and the chain block 5 form a mould moving structure system, and the sleeve construction method solves the problems that the traditional wood formwork cannot be moved in a turnover mode and a large steel mould is difficult to move. The system can move the large side wall template of about 1t to the next standard section for installation by using the sliding rail system by only 2-3 persons. The system can greatly reduce the cost of manpower, mechanical machine shifts and the like. The greatest innovation and improvement is made by using the traditional materials, so that the whole system can be improved to the greatest extent.
The design of the single support 7 of the side wall template 8 can reduce the arm supporting system formed by profile steel adopted by the back edge of the traditional large steel template. Meanwhile, the weight of the formwork system is reduced, the fact that the single supports 7 and the side wall formworks 8 move together to a next standard section for installation and use is considered when the single supports 7 are designed, a sliding groove is formed in a back edge of a steel frame formwork of the side wall formworks 8, the single supports 7 can conveniently move up and down to adjust the supporting positions, and meanwhile the sliding rail system is used for moving the single supports 7 to the next standard section together when the formwork is disassembled.
The invention adopting the technical scheme innovatively subverts the use structure form of the traditional steel pipe full-framing red formwork support system in the first pouring process in the tunnel. Firstly, the bearing capacity of a truss system can optimize the steel pipe support of the traditional side wall template to the maximum, the distance between the existing steel pipe supports of 400mm multiplied by 600mm is changed into 1500mm multiplied by 1200mm, and the distance between the upright rods of the scaffold is changed into 900mm multiplied by 1200mm from the original 600mm multiplied by 600 mm; meanwhile, the steel frame wood formwork system is combined with the sliding rail, so that the problem that the wood formwork cannot be moved in a turnover mode is solved. The truss support slip form system is safe and efficient, changes and innovations of the existing tunnel support system can be achieved, material cost, labor cost, mechanical cost, transportation cost and the like can be well saved, evolution of the whole tunnel concrete structure support system from complexity to simplicity is achieved optimally, and meanwhile subversive innovation is generated on the tunnel support system.
