Description
Technical Field
The utility model belongs to the technical field of railway tunnel concrete curing, and particularly relates to a railway tunnel low side wall curing device.
Background
When the railway tunnel is constructed, the cross section is formed by side walls positioned at two sides, a vault positioned above the two side walls and an inverted arch positioned below the two side walls, and the inverted arch is in an arc shape. When the concrete of the side walls on two sides is constructed, the reinforcement cages of the concrete of the side walls are correspondingly fixed on the side walls, then when pouring, the parts positioned at the lower ends of the side walls on two sides are poured firstly, namely, the short side walls are poured firstly, after the concrete of the short side walls reaches a certain strength, the reinforcement cages of the short side walls are detached, and then, the parts of the short side walls are poured, except for the parts of the short side walls, so that the quality of the concrete on the short side walls is guaranteed, and manual water spraying maintenance can be carried out on the short side walls. The maintenance mode not only needs a large amount of manpower resources to carry out maintenance, but also is easy to cause the conditions of untimely maintenance or insufficient maintenance.
Disclosure of Invention
The utility model aims to provide a low side wall maintenance device for a railway tunnel, which reduces the investment of human resources and effectively avoids the condition that maintenance is not in time or in place.
The technical scheme adopted by the utility model is as follows: the utility model provides a low side wall curing means of railway tunnel, includes the water supply pipe, the water supply pipe sets up at the top of low side wall concrete through colluding the muscle, and the water supply pipe sets up along the direction that the tunnel extends, collude the muscle and wholly be the U-shaped, the water supply pipe is lived to the bottom pocket, and the both ends are hung on the steel reinforcement cage on the side wall, the interval is provided with a plurality of shower towards low side wall concrete around on the water supply pipe, is covered with the covering that is used for heat preservation moisturizing on low side wall concrete.
Preferably, in the above scheme, one end of the water supply pipeline is blocked, and the other end is connected with a water pump.
Further preferably, the cover is geotextile.
Further preferably, the water supply pipe is provided with a tee at a position corresponding to each shower pipe.
Further preferably, one end of the hooking bar is hooked on the inner side of the side wall reinforcement cage, and the other end of the hooking bar is hooked on the outer side of the side wall reinforcement cage.
Further preferably, the spray pipe adopts an atomization spray nozzle.
The utility model has the beneficial effects that: when the low side wall is cured, water is sprayed to the low side wall concrete from top to bottom through the spray pipe, then the temperature and the humidity of the low side wall concrete are guaranteed under the action of the cover, automatic curing is adopted, the investment of human resources is reduced, the safety risk of manually curing the concrete is reduced, the curing is convenient, the working efficiency is improved, the condition that the curing is not timely or the curing is not in place in the prior art can be avoided, and the quality of the low side wall concrete entity can be effectively improved.
Drawings
FIG. 1 is a schematic diagram of the present utility model.
Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in fig. 1, a maintenance device for a short side wall of a railway tunnel mainly comprises a water supply pipeline 1 and a covering 5, wherein the covering 5 covers the short side wall concrete and has the functions of heat preservation and moisture preservation, the water supply pipeline is arranged at the top of the short side wall concrete through a hooking rib 2, and the water supply pipeline 1 is arranged along the extending direction of the tunnel. In order to facilitate the fixation of the hooking bars, the hooking bars 2 are integrally U-shaped, the bottom is covered on the water supply pipeline 1, and the two ends of the hooking bars are hung on the reinforcement cage 3 on the side wall. In order to realize the maintenance of the short side wall concrete, a plurality of spray pipes 4 facing the short side wall concrete are arranged on the water supply pipeline 1 at intervals. In order to facilitate the spray pipe to directly spray larger water column to the short side wall concrete, the spray pipe adopts an atomization nozzle.
In order to ensure the normal water supply of the water supply pipeline, one end of the water supply pipeline is plugged, and the other end of the water supply pipeline is connected with a water pump.
In this embodiment, geotextiles are used for the cover, as geotextiles are readily available.
In order to realize that the spray pipes spray water towards the top of the short side wall concrete, a tee joint is arranged on the water supply pipeline 1 at a position corresponding to each spray pipe 4.
In order to ensure the fixation when hooking the reinforcing bars, one end of the reinforcing bar 2 is hooked on the inner side of the side wall reinforcing bar cage 3, and the other end is hooked on the outer side of the side wall reinforcing bar cage 3.
