Abstract

The invention discloses a concrete curing system for a tunnel with an ultra-large cross section. The concrete curing system comprises a curing track, a sliding device connected with the curing track and a spraying device connected with the sliding device. Wherein the spraying device comprises an arc-shaped spraying pipeline, the spraying pipeline is arranged in the arc-shaped direction of the tunnel and connected with the sliding device, a plurality of spraying units are arranged on the spraying pipeline, and when liquid is introduced into the spraying pipeline, the spraying units spray the tunnel face. According to the concrete curing system for the tunnel with the super-large cross section, the curing track is fixedly connected to the concrete tunnel face where pouring is completed, then the spraying pipeline is connected with the curing track, spraying is conducted along the concrete tunnel face where pouring is completed, and full-automatic spraying operation is achieved; and manual walking on the maintenance rack is replaced for spraying, so that the labor force is reduced, and the potential safety hazard of manual operation can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of tunnel maintenance and construction, and in particular relates to a super-large-section tunnel concrete maintenance system. Background technique [0002] During tunnel construction, as the excavation damages the original balance of the surrounding strata, it is easy to cause deformation or collapse of the tunnel. In order to protect the stability of the surrounding rock, concrete lining is usually carried out along the periphery of the tunnel body to build a supporting structure during the excavation process of the tunnel, so as to ensure the safety of the tunnel construction. However, if the concrete is not maintained in time after pouring, the moisture in the concrete will evaporate quickly and cause the concrete to dehydrate, which will cause the concrete surface to fall off or shrink and deform to cause cracks, which will eventually affect the stability of the structure. Among them, due to the large ...
