[0002] With the development of rail transit, the requirements for quality, safety and environmental protection of various tunnels and tunnels are constantly increasing. In underground construction projects confined to small spaces, problems such as high energy consumption, high pollution, high risks and low efficiency are becoming more and more apparent. In concealed construction and special construction projects with short construction cycles, fast construction speeds and strict process requirements, composite lining structures often suffer from quality defects such as gaps, falling off, water leakage and infiltration in the secondary lining concrete, and relatively severe vertical cracking of the lining.

[0003] The method of combining a precast membrane shell with cast-in-place concrete can effectively improve the safety and durability of secondary lining. However, due to the process, preform number, and weight restrictions imposed by mining laws, it is difficult to combine a precast membrane shell with a prefabricated lining machine to form a set. This problem has restricted the mechanized and industrialized construction of tunnels and tunnels. In conventional technology, secondary lining work is generally completed using a construction cart, but the lift-up module of the conventional construction cart is generally installed as an integrated unit, which poses a technical problem: the installation angle of the precast membrane shell cannot be flexibly adjusted according to the construction environment.

[0019] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present invention, the following clearly and completely describes the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

For example, two processes described as successive may be performed essentially simultaneously or may be performed in the reverse order from that described. Note that like reference numerals refer to like components.

[0021] Example 1 One specific embodiment of the present invention discloses a lift-up module for a secondary lining construction vehicle, as shown in Figures 1 to 5, The solar cell includes a first submodule 1 and a second submodule 2, and the first submodule 1 and the second submodule 2 are installed separately and opposite to each other, Each of the first sub-module 1 and the second sub-module 2 includes at least two tripod sets 10, two arc frames 11, and an adjustment tool 12; The tripod set 10 includes a first tripod 101 and a second tripod 102, and a first connecting pipe 103, a second connecting pipe 104, and a third connecting pipe 105 are provided between the first tripod 101 and the second tripod 102; One end of the adjusting device 12 is articulated to the first connecting pipe 103 via a connecting device 120, the other end is articulated to one end of the arc-shaped frame 11, the other end of the arc-shaped frame 11 is articulated to the tripod set 10 via the second connecting pipe 104, and the third connecting pipe 105 is used to connect the first tripod 101 and the second tripod 102.

[0022] In practice, first, according to the actual construction needs, the first sub-module and the second sub-module are attached to the secondary lining construction cart, then the precast membrane shell is placed on the arc-shaped frame 11 and fixed, and then the secondary lining construction cart is moved to the construction position, and then the height of the arc-shaped frame 11 is adjusted using the adjustment device 12, the precast membrane shell is attached to the specified position, concrete is poured into the precast membrane shell, and after the concrete has hardened, the arc-shaped frame is contracted to complete the construction.

[0023] Compared with the prior art, the lift-up module of the secondary lining construction trolley in this embodiment includes a first sub-module and a second sub-module that are installed separately and opposite each other, and the height and angle of the arc-shaped frame can be adjusted using an adjustment tool to install the precast membrane shell in a predetermined position, thereby meeting different construction needs and enabling the installation angle of the precast membrane shell to be flexibly adjusted according to the construction environment.

[0024] In this embodiment, two adjacent tripod sets 10 are detachably connected by a connecting round pipe 13 .

[0025] Specifically, two adjacent tripod sets 10 belonging to the same module are detachably connected by the connecting round pipe 13 or by an extendable connecting rod, making it easy to install and remove lift-up modules and to install membrane cases of different lengths.

[0026] In this embodiment, the arc-shaped frame 11 includes a first arc-shaped pipe 110, a second arc-shaped pipe 111, and a third arc-shaped pipe 112, and the ends of the first arc-shaped pipe 110, the second arc-shaped pipe 111, and the third arc-shaped pipe 112 that are far from the tripod set 10 intersect at one point, and the spatial distribution near the other end of the tripod set 10 forms a triangle. The ends of the second arc-shaped pipe 111 and the third arc-shaped pipe 112 that are close to the tripod set 10 are connected by a fourth connecting pipe 114, and the end of the first arc-shaped pipe 110 that is close to the tripod set 10 is connected to the fourth connecting pipe 114 by an inclined connecting pipe 113.

[0027] Specifically, one end of the first arc-shaped pipe 110, the second arc-shaped pipe 111, and the third arc-shaped pipe 112 intersect at one point, the other ends of the second arc-shaped pipe 111 and the third arc-shaped pipe 112 are connected by a fourth connecting pipe 114, and the other end of the first arc-shaped pipe 110 is connected to the fourth connecting pipe 114 by the inclined connecting pipe 113, so that the arc-shaped frame 11 has a triangular pyramid shape and stabilizes the entire structure.

[0028] In this embodiment, the fourth connecting pipe 114 is provided coaxially with the second connecting pipe 104 so as to articulate the arc frame 11 to the tripod 10 .

[0029] Specifically, the diameter of the fourth connecting tube 114 is slightly larger than the diameter of the second connecting tube 104 and the length is slightly smaller, and the fourth connecting tube 114 is inserted into the second connecting tube 104 to articulate the arc-shaped frame 11 to the tripod set 10.

[0030] In this embodiment, the midpoint of the first arc-shaped pipe 110 is connected to the trisection points of the second arc-shaped pipe 111 and the third arc-shaped pipe 112 by round pipes, respectively.

[0031] Specifically, by connecting the midpoint of the first arc-shaped pipe 110 to the trisection points of the second arc-shaped pipe 111 and the third arc-shaped pipe 112 using round pipes, a triangular structure is formed between the first arc-shaped pipe 110, the second arc-shaped pipe and the third arc-shaped pipe, thereby improving the stability and loading capacity of the arc-shaped frame 11.

[0032] In this embodiment, the surface of the first arc-shaped pipe 110 is covered with a protective layer, and the material of the protective layer is thermoplastic urethane rubber, chlorinated polyethylene or styrene butadiene rubber.

[0033] Specifically, the protective layer is made of a wear-resistant and corrosion-resistant material, and by covering the surface of the first arc-shaped pipe 110 with it, the precast membrane shell can be prevented from coming into direct contact with the first arc-shaped pipe 110 and being worn, thereby protecting the precast membrane shell and at the same time extending the service life of the arc-shaped frame 11.

[0034] In this embodiment, the ends of the adjuster 12 connected to the arc frame 11 are articulated to the second arc pipe 111 and the third arc pipe 112 respectively.

[0035] For example, two adjusting devices 12 are used in combination with each of the arc-shaped frames 11, one end of which is articulated to the first connecting pipe 103, and the other end of which is articulated to the second arc-shaped pipe 111 and the third arc-shaped pipe 112, respectively, thereby providing the arc-shaped frame 11 with more stable supporting force.

[0036] In this embodiment, the adjuster 12 is an air cylinder or a hydraulic cylinder, which is configured to provide lift-up support for the arc frame 11 and adjust the height and angle of the arc frame 11.

[0037] For example, the adjusting device 12 may be any device with a lifting function, such as an air cylinder, a hydraulic cylinder, a screw rod, etc., and the height and angle of the arc-shaped frame 11 can be adjusted by raising and lowering the adjusting device 12 to adapt to a variety of construction conditions.

[0038] In this embodiment, the connecting device 120 has two circular holes of different diameters for drilling the adjusting device 12 and the first connecting tube 103 respectively so as to articulate the adjusting device 12 to the first connecting tube 103.

[0039] Specifically, the connecting device 120 is fitted into the adjusting device 12, and the first connecting pipe 103 and the adjusting device 12 are respectively drilled into two circular holes of different diameters, so that the adjusting device 12 and the first connecting pipe 103 form an articulated connection relationship, thereby adjusting the height and angle of the arc-shaped frame 11.

[0040] In this embodiment, the arc-shaped frame 11 of the first sub-module 1 is the same size as the arc-shaped frame 11 of the second sub-module 2, and the first arc-shaped pipe 110, the second arc-shaped pipe 111, and the third arc-shaped pipe 112 of two adjacent arc-shaped frames 11 belonging to the same first sub-module 1 or second sub-module 2 are connected at their intersections by a first connecting horizontal pipe 14, and the other ends of the first arc-shaped pipes 110 are connected by a second connecting horizontal pipe 15.

[0041] Specifically, the lift-up module according to this embodiment has a radian

number

[0042] <Example 2> Another specific embodiment of the present invention differs from embodiment 1 in that, as shown in Figures 6 and 7, the arc-shaped frames 11 of the first sub-module 1 and the second sub-module 2 are arranged alternately, and the first connecting horizontal pipe 14 is arranged between the midpoints of the first arc-shaped pipes 110 of two adjacent arc-shaped frames 11 of the same module.

[0043] Specifically, the lift-up module according to this embodiment has a radian

number

[0044] Example 3 Another specific embodiment of the present invention differs from embodiment 2 in that, as shown in Figures 8 and 9, the sizes of the two arc-shaped frames 11 are such that one is larger and the other is smaller, and the first connecting horizontal pipe 14 and the second connecting horizontal pipe 15 are not provided.

[0045] Specifically, the lift-up module according to this embodiment has a radian
