Embodiment 1

[0039] A plugging device for lining construction, see Figure 1-6 , including an airbag component 1 (one airbag is shown here, and a plurality of parallel airbags can also be used for combination) and a group of blocking single pieces 2 or at least two groups of blocking single pieces 2 arranged side by side ( Figure 5 Three groups are shown in ), the details are as follows:

[0040] The airbag in the airbag component 1 is an industrial airbag, and the specifications can be designed according to actual needs.

[0041] The blocking unit 2 includes a fixed plate 2.1 and an adjustable connection template 2.2, specifically:

[0042] The fixing plate 2.1 is detachably connected or fixedly connected to the lining template 7 on the lining trolley.

[0043] The first end of the adjustable connection template 2.2 is movably arranged on the fixed plate 2.1 through the connector 2.3; the second end of the adjustable connection template 2.2 is provided with a mounting part 2.21 for set...

Abstract

The invention provides a plugging device for lining construction. The plugging device comprises an airbag part and at least one set of plugging single pieces. Each plugging single piece comprises a fixing plate and an adjustable connecting template. The first end of each adjustable connecting template is movably arranged on the corresponding fixing plate through a connecting piece. The second endof each adjustable connecting template is provided with a mounting part used for arranging of the airbag part. Each mounting part is internally provided with a cavity used for accommodating a water stop part. The cavities are formed by corresponding to the airbag part. By applying the technical scheme, the effects are that the structure is simplified; through combination of the airbag part, the fixing plate and the adjustable connecting templates, the templates are built without need of taking a lot of time, meanwhile, perfect fit between the airbag part and the water stop parts as well as theairbag part and the excavation surface can be achieved, and the lining quality is improved; and the adjustable connecting templates are movably arranged on the fixing plates through the connecting pieces, the positions of the adjustable connecting templates and the fixing plates can be adjusted according to the actual working condition, the construction demand of different sections is met, and universality is high.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a plugging device for lining construction. Background technique [0002] During the tunnel lining process, the sealing device is installed at the front end of the formwork to prevent the concrete from overflowing during pouring. Existing blocking devices have the following types: [0003] 1. Use wooden molds to block on site. This method requires a large number of wooden molds and takes a long time to build. It is complicated to install water-stop parts on the built wooden molds, and the water-stop effect is not good. [0004] 2. The combined steel mold is used for sealing. The combined sealing mold is composed of a lower fixed formwork, an upper flipped formwork, an external wooden formwork, a strut, an I-beam base and a hinge pin. The defects of this kind of plugging device are: complicated structure, inconvenient to use; various specifications of plugging templat...
