Abstract

The invention discloses a mobile tunnel supporting structure and a tunnel construction method implemented under the protection effect of the mobile tunnel supporting structure. The mobile supporting structure consists of a plurality of boxes which are connected to one another in a gripped manner according to the shape of the outer contour of a tunnel; a shield which extends rearwards is arranged at the tail of each box; and under the protection effect of the mobile supporting structure consisting of the boxes which are gripped to form a ring and the shields at the tails of the boxes, tunnel excavation and lining can be carried out safely and quickly. The tunnel construction method implemented under the protection effect of the mobile tunnel supporting structure mainly comprises the following steps of land preparation, assembly of the mobile supporting structure, mounting debugging of construction equipment, positioning of the mobile supporting structure and positioning of the equipment, tunnel excavation and assembly or primary supporting construction of prefabricated members. By the mobile supporting structure, slidable tunnel advance supporting can be implemented; and multi-ring tunnel advance supporting construction is not required under the condition of a complex formation, the equipment does not need to be detached or mounted repeatedly, cost is reduced, and the work efficiency is improved. Moreover, the construction method has high safety and high universality, and is convenient and easy to implement.

Description

technical field

[0001] The invention relates to the field of tunnel construction, in particular to a mechanized mobile support structure and a tunnel construction method under protection thereof. Background technique

[0002] Tunnel construction can be mainly divided into manpower-based mining method and mechanical-based shield method. At present, the urban subway section is mainly constructed by the shield tunneling method, while most other tunnels still use the human-based mining method. As tunnel construction faces complex geological conditions, ground environment, and increasing labor costs, the mechanization level of mine construction needs to be improved urgently. Especially in some weak surrounding rock conditions, mining method construction is particularly difficult. In order to ensure construction safety and effectively control the deformation of the surrounding rock, weak surrounding rock needs to be strengthened or supported in advance, such as grouting, pipe sh...

Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0052] Such as Figure 1-4 As shown, a tunnel mobile support structure of the present invention includes a box group structure 6 and a shield group structure 9,

[0053] The box group structure 6 is formed by snapping together a plurality of boxes 1 according to the shape of the outer contour of the tunnel, and a shield 7 is arranged on each box 1, and the shield is placed on the box. The outer panel extends backward with a certain length of plate structure; when ...
