Description

Novel seepage-proofing gallery

Technical Field

The utility model relates to a water conservancy water and electricity building construction technical field especially relates to a novel prevention of seepage corridor that construction environment protection and security are strong.

Background

At present, in hydraulic and hydroelectric engineering, galleries are widely applied to all parts of engineering and can be used as grouting construction passages, transportation, placement equipment and the like. The gallery is generally of a tunnel type, is lined by concrete full-section lining, and has a small tunnel section and a narrow construction operation space. Most galleries do not consider the water passing working condition in the design, and meanwhile, the external water is small, so that the design of crack limiting is not generally needed, and the requirement of stable structure of the galleries is mainly met. The conventional construction method of the gallery comprises the following steps: the side wall of the gallery is constructed by matching small steel moulds with brace vertical moulds, and the vault is constructed by erecting scaffolds by bulk steel pipes for vertical mould lining. The formwork stripping operation of the vertical formwork is complex, time and labor are wasted, a large amount of materials are consumed, and the construction efficiency is low. In actual engineering, water in a mountain body often seeps out of the top of the gallery to affect construction equipment and construction environment, and after water seepage, special grouting measures are often needed to be adopted for treatment of the water seepage position, so that the cost is high.
