Description

Technical Field

[0001] The utility model relates to the technical field of utility tunnel construction, in particular to a curing tool for the cast-in-situ structure of a utility tunnel. Background Technique

[0002] Generally, it is set below the center of the road or in the utility tunnel belt outside the road red line. It mainly transports from the main pumping stations (such as water treatment plants, power plants, gas manufacturing plants, etc.) to the branch utility tunnels, and generally does not directly serve the areas along the line. The pipelines it mainly houses are power, communication, tap water, gas, heat, etc. pipelines. Sometimes, drainage pipelines are also housed according to needs. In the main utility tunnel, power is transported from the ultra-high voltage substation to the primary and secondary substations, communication is mainly for signal transmission between switching centers, and gas is mainly for transportation between the gas plant and the high-pressure regulating station. The cross-section of the main utility tunnel is usually circular or multi-cell box-shaped. Generally, working channels, lighting, ventilation and other equipment are required to be set in the utility tunnel. The main characteristics of the main utility tunnel are: stable large-flow transportation, high safety, compact internal structure, taking into account direct supply to large users with stable use, generally requiring special equipment, and relatively simple management and operation.

[0003] During the actual construction of the utility tunnel, cast-in-situ construction is generally adopted. During actual construction, a segmental casting construction method is generally presented. The overall cross-section of the tunnel shows a rectangular structure. After the tunnel is cast, it is necessary to spray and cure the cast-in-situ structure of the utility tunnel. During the curing process of the main side wall in the tunnel, sprinkler curing is generally used for the side wall. In the prior art, the following problems exist: Currently, mainly workers use water pipes to spray water on the side walls. Due to the high side walls, manual operation is difficult, and it is difficult to comprehensively cure the entire wall surface. The number of curing times is small and it is difficult to achieve the expected curing effect, which may cause shrinkage cracks in the side wall concrete. Therefore, there are certain limitations. In view of the above defects, it is urgent to solve the curing problem of the existing tunnel side walls. Content of the Utility Model
