Embodiment Construction

[0016] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0017] reference Figure 1-Figure 4 , An inflatable mold for tunnel concrete lining, comprising: an inner tube 1 and an outer tire 2 arranged concentrically, the diameter of the outer tire 2 is the same as the radius after the tunnel is lined, and the radius of the inner tire 1 is smaller than the radius of the outer tire 2;

[0018] It also includes a stiffening rib. The stiffening rib includes a first part 3 arranged concentrically with the inner tube 1 and a second part 4 extending in the radial direction; the first part 3 is arranged inside the inner tube 1, and the second part 4 is connected to Between the first part 3 and the inner tube 1;

[0019] The inflatable mold is further provided with an inflatable hole 4, a connecting hole 5, and a fixed pile groove 6 on the inner side of the first part 3; the inflatable hole 4 is connected to the inner tube 1, and ...

Abstract

The invention provides a tunnel concrete lining inflation mold. The tunnel concrete lining inflation mold comprises an inner tube and an outer tube. The inner tube and the outer tube are concentrically arranged. The diameter of the outer tube is equal to the radius of a lined tunnel, and the radius of the inner tube is smaller than that of the outer tube. The tunnel concrete lining inflation moldfurther comprises a tightening rib. The tightening rib comprises a first portion and second portions. The first portion and the inner tube are concentrically arranged, and the second portions extend in the radial direction. The first portion is arranged on the inner side of the inner tube, and the second portions are connected between the first portion and the inner tube. The tunnel concrete lining inflation mold further comprises inflation holes, a connecting hole and fixing pile grooves. The inflation holes, the connecting hole and the fixing pile grooves are formed in the inner side of thefirst portion. The inflation holes communicate with the inner tube, the connecting hole is used for being connected with other inflation molds, and the fixing pile grooves are used for fixing the inflation mold to the ground. The tunnel concrete lining inflation mold saves the investment and is easy to operate.

Description

Technical field [0001] The invention relates to highway tunnel engineering. Background technique [0002] At present, the concrete lining of highway tunnels usually adopts steel form jumbo. The steel form jumbo has the advantages of high mechanization, low labor intensity, and no misalignment of the lining concrete, but it also has high cost, heavy weight, high customization and assembly expertise. , Long cycle characteristics. Summary of the invention [0003] The main technical problem to be solved by the present invention is to provide an inflatable mold for tunnel concrete lining, which saves investment and is simple to operate. [0004] In order to solve the above technical problems, the present invention provides an inflatable mold for tunnel concrete lining, including: an inner tube and an outer tube arranged concentrically, the diameter of the outer tube is the same as the radius of the tunnel lining, and the radius of the inner tube is smaller than the radius of the outer ...
