Auxiliary equipment and construction technology for tunnel concrete lining construction

Abstract

The invention discloses auxiliary construction equipment for a concrete lining of a tunnel and a construction process and belongs to the technical field of tunnel construction. The auxiliary construction equipment comprises a formwork and a bracket. The bracket supports the formwork to enable a preset space to be formed between the bracket and tunnel surrounding rock; the formwork comprises a plurality of sub-formworks detachably connected; the total length of the multiple sub-formworks is set in the mode that after concrete is poured into the part, between the sub-formwork at the tail end ofthe formwork and the tunnel surrounding rock, of the preset space, concrete in the part, between the sub-formwork at the head end of the formwork and the tunnel surrounding rock, of the preset space reaches the preset solidifying state; the bracket comprises two sub-brackets adjustable in width; and when the width of one of the sub-brackets is decreased, the sub-bracket can be separated from supporting of the formwork and can move in the length direction of the bracket by the distance of the length of the at least one sub-formwork. According to the auxiliary construction equipment for the concrete lining of the tunnel, concrete lining construction is continuous and uninterrupted, the construction efficiency is improved, and manpower and material resources are arranged reasonably.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel concrete lining auxiliary equipment and construction technology. Background technique [0002] Tunnels are an important transportation facility. When constructing subways and mountain roads, tunnels are required. Usually, in order to ensure the safe use of the tunnel, a concrete lining formed of concrete is provided along the surrounding rock of the tunnel body. The concrete lining forms permanent support for the surrounding rock of the tunnel to avoid the collapse of the surrounding rock of the tunnel. It can be seen that it is very important to construct concrete lining in tunnel construction. [0003] In the prior art, brackets and templates are used as auxiliary equipment when constructing the concrete lining of the tunnel. Specifically, the support includes a joist, and a top beam fixed on the joist and arranged along the length direction of the tunne...
