Embodiment 1

[0045] In order to solve the problem that trolleys and other operating equipment are not easy to erect and move due to the irregular construction site during the construction process of tunnel drilling and blasting, a new type of operating platform is provided, as shown in the attached figure 1 As shown, the working platform mainly includes an arch support 1 , a main traveling mechanism 2 and an auxiliary traveling mechanism 3 .

[0046] Specifically, the arched support 1 is an arc-shaped truss member, and its outer arc shape is similar to the shape of the tunnel arched inner wall 61, which can ensure that the entire arched support 1 is close to the tunnel arched inner wall. The top of the platform is parallel to the cross-section of the arched inner wall of the tunnel, so that when the entire work platform is moving, it can avoid collision with the arched inner wall of the tunnel.

[0047] combine figure 2 As shown, in different construction sections inside the tunnel, the ...

Embodiment 2

[0059] Embodiment 1 belongs to a light-duty work platform, which can be used in construction procedures that do not need to bear a large load, such as scanning the inner wall of a tunnel. In order to further improve other construction procedures that need to bear relatively large loads, this embodiment provides another working platform solution on the basis of the first embodiment.

[0060] Specific as Figure 6 As shown, while the arched support 1 is suspended and connected to the tunnel arched inner wall 61 through the main traveling mechanism 2 and the auxiliary traveling mechanism 3, in order to realize the construction process that the arched support 1 can bear a greater load, the arched support 1 is also An auxiliary support system 5 is set up. After the arch support 1 is moved to a fixed position, the support between the arch support 1 and the tunnel arch inner wall 61 and the tunnel floor 62 is formed to provide auxiliary support for the working platform during constru...

Embodiment 3

[0066] This embodiment provides a continuous operation system for tunnel construction based on Embodiment 1 and Embodiment 2, specifically as Figure 7 , Figure 8 and Figure 9 As shown, it includes multiple sets of working platforms on the upper and lower steps inside the tunnel. The working platforms in different construction sections are equipped with corresponding construction equipment heads to carry out construction on the inner wall of the tunnel corresponding to the construction section. After a construction section is completed, the The working platform in the following construction section moves forward through the traveling mechanism to realize continuous construction operations in the tunnel.

[0067] The following combination Figure 8 and Figure 9 Describe in detail.

[0068] Such as Figure 8 As shown, three sets of hoop traveling mechanisms 4 are arranged on the arched support 1 of the working platform in the figure, and each set of hoop traveling mechan...

Abstract

The invention discloses an operation platform and a continuous operation system and operation method for tunnel construction thereof. The operation platform comprises an arch support similar to the transverse shape of the arched inner wall of a tunnel and a traveling system for enabling the arch support to move in the longitudinal direction of the tunnel. The traveling system includes a main traveling mechanism and auxiliary traveling mechanisms. The arch support is connected to a suspended rail in a suspended mode by the main traveling mechanism, and the arch support is connected to supporting rails in a supporting mode by the auxiliary traveling mechanisms. A circumferential traveling mechanism for carrying a machine head of construction equipment is arranged on the arch support in the circular arch direction of the arch support. By using the continuous operation system for the tunnel construction of the operation platform, a brand new tunnel drilling and blasting construction methodis provided, the technical problems of irregularity of a construction site, various excavation methods and low equipment universality in the construction process of the drilling and blasting method are effectively solved, and foundation and condition are laid for the full mechanization and unmanned construction of the tunnel of the drilling and blasting method.

Description

technical field [0001] The invention belongs to tunnel construction technology, in particular to an operation platform and its continuous operation system and operation method for tunnel construction. Background technique [0002] In the era of smart construction, fully mechanized and unmanned construction is an inevitable trend in the development of tunnel engineering technology. Drill and blast and shield tunneling are the two main methods of tunnel construction. At present, the shield tunneling method can realize the mechanized construction of the whole process, such as excavation, slag extraction, segment assembly, back grouting, etc., by using a complete set of large-scale shield machines. In theory, unmanned construction can be achieved. The construction of tunnels by drilling and blasting method includes various processes such as excavation, support, waterproof layer laying, lining pouring, and lining maintenance. big difficulty. However, the drill and blast method...
