Problems solved by technology
The disadvantage of this method is that after adjusting the height and width of the gantry, it is necessary to reinstall and adjust the formwork, the workload is heavy, the construction speed is slow, and there are many parting lines on the lining surface, which is not beautiful and easy to run out of the mold

Embodiment Construction
[0019] Such as Figure 4 , Figure 5 As shown, the general formwork of the steel formwork trolley for tunnel lining construction includes a plurality of formwork units composed of a rectangular formwork formwork and formwork frames 1 arranged around the formwork formwork. In order to make it universal, The curved formwork is a rectangular formwork 2 formed by bending along its short sides; formwork connection holes 3 are evenly distributed on the longitudinal plate surfaces of the two long sides of the formwork frame 1; Formwork installation holes 5 are evenly distributed on the bottom frame 4 (the surface connected with the arch 6 ).
[0020] In order to use the elastic deformation of the rectangular formwork 2 to eliminate the gap between the formwork and the section profile of the tunnel to be lined, the outer arc chord length L of the rectangular formwork 2 is greater than 0.9m. Generally, the effect is better when L is greater than 1.2m. The radius of the outer arc is R...

The invention discloses a universal formwork of a steel mould trolley for tunnel lining construction. The universal formwork comprises a plurality of formwork units, wherein each formwork unit consists of an arc-shaped formwork of a rectangular structure and a formwork framework arranged on the periphery of the arc-shaped formwork; each arc-shaped formwork is a rectangular formwork formed through being bended along the short edge; formwork connecting holes are uniformly distributed in the longitudinal surface of the two long edges of each formwork framework; and formwork installing holes are uniformly distributed in bottom side frames between the two long edges of the formwork frameworks separately arranged above the rectangular formworks. The universal formwork has the advantages that the formwork units are changed to be bent along the short edges to form a rectangular formwork, so that the length in the axial line direction of a tunnel is long, and the length in the cross section direction of the tunnel is short; an arch frame is provided according to the actual cross section radius of the tunnel; the formwork generates elastic deformation by using screwing force of connecting screw bolts; a gap between the rectangular formwork and a tunnel to be lined is eliminated; the anastomosis of the installed formwork and the cross section of the lined tunnel is ensured, so that only one set of universal formwork is needed in the construction of the tunnel cross sections with similar radii; and the lining cost is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of concrete lining construction equipment for high-speed railway tunnels, expressway tunnels, water diversion tunnels, underground caves, culverts, etc., and in particular to a steel mold trolley for tunnel lining construction that can adapt to changes in arc dimensions within a certain range The general formwork, the present invention also relates to the installation and use method of the general formwork. Background technique [0002] The steel formwork trolley is a special mechanical construction equipment for pouring the tunnel lining concrete according to the different contours of the tunnel and the different pouring methods of the tunnel lining concrete during tunnel construction. It has the advantages of low cost and convenient use. It is used in railways, It is widely used in the construction of highways, water conservancy and hydropower projects. The use of formwork trolley can not only avoid const...
