Abstract
The utility model relates to tunnel construction equipment, in particular to a tunnel secondary lining concrete curing trolley which solves the problems of influence on the integrity and durability due to the insufficiency of hydration of the existing tunnel secondary lining concrete curing. The tunnel secondary lining concrete curing trolley comprises a door frame, wherein the bottom of the door frame is provided with a road wheel, an arc-shaped steel tube is arranged outside the upper part of the door frame, water drainage holes are uniformly arranged outside the steel tube, and one end part of one side of the steel tube is connected with a water pipe connector. The tunnel secondary lining concrete curing trolley can solve the problems of insufficient strength of concrete, crack, and the like due to insufficient curing of secondary lining, is beneficial to the improvement of the integrity and durability of secondary lining and ensures the construction quality of secondary lining tunnel concrete.
Description
Technical field
The utility model relates to constructing tunnel equipment, is specially a kind of tunnel double-lining concrete curing chassis.
Background technology
After the tunnel double-lining construction is finished, there is concrete strength deficiency in various degree, or even the concrete cracking phenomenon.Generally speaking, lining concrete strength deficiency and cracking are very complicated system problems, and influence factor is a lot, but temperature and humidity has the greatest impact to concrete strength deficiency and cracking.
In present most of constructing tunnel, temperature is higher in the hole, dryness of air.The temperature height, hydrated cementitious speeds up, and concrete strength developing is also fast, and water is the necessary condition of hydrated reaction of cement, has only ambient humidity suitable, hydrated reaction of cement could carry out smoothly, and concrete strength is attained full development.If humidity is not enough, hydrated reaction of cement can not normally carry out, even stops aquation, can seriously reduce concrete strength.Hydrated cementitious is insufficient, and hydration is not finished, and also can make concrete structure loose, forms cup shake, increases seepage of water, thereby influences concrete globality and durability.
Summary of the invention
There is the insufficient problem that influences globality and durability of aquation in the utility model in order to solve existing tunnel two lining concrete curings, and a kind of tunnel double-lining concrete curing chassis is provided.
The utility model is to adopt following technical scheme to realize: tunnel double-lining concrete curing chassis, comprise door frame, the door frame bottom is provided with road wheel, and the door frame upper outside is provided with the steel pipe of arcuation, the uniform spilled water hole that has in the outside of steel pipe, steel pipe one side end is connected to water pipe head.When carrying out the secondary maintenance, connect water pipe head on high-pressure water pipe and the steel pipe with flexible pipe, open gate valve, with the artificial trolley running that promotes, water sprays from spilled water hole, can serve as a contrast the surfaces maintenance of sprinkling water to two.
The utility model can solve concrete strength deficiency and the problems of crack because of two lining maintenances appearance not in place preferably, helps improving two lining globality and durability, guarantees the tunnel double-lining concrete construction quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-door frame, 2-road wheel, 3-steel pipe, 4-water pipe head, 5-reinforcing bar.
The specific embodiment
Tunnel double-lining concrete curing chassis comprises door frame 1, and door frame 1 bottom is provided with road wheel 2, and door frame 1 upper outside is provided with the steel pipe 3 of arcuation, the uniform spilled water hole that has in the outside of steel pipe 3, and steel pipe 3 one side ends are connected to water pipe head 4.In the specific implementation process, steel pipe 3 adopts Φ 48 coating steel pipes to make, and section configuration is reserved ventilation cloth bag position simultaneously than the little 15--20cm of two lining sections; Interval 15cm-20cm fires spilled water hole on the steel pipe 3; Door frame adopts the H14 section steel manufacture, adopts reinforcing bar 5 welding of Φ 20 fixing between steel pipe 3 and the door frame 1.
