Abstract
A self-moving spray curing device for two-lining concrete in a tunnel is characterized in that a flat slide rod is sleeved in a flat sleeve on a moving portal frame, a displacement rack at the top is meshed with a driving gear of a driving speed reducer, a water storage tank is communicated with a booster pump and connected with one end of a high-pressure water pipe, a water supply hose at the other end is connected with a spray pipe and an atomizing nozzle, two ends of the flat sleeve are respectively fixed with a limit switch, when the self-moving spray curing device is used, the driving speed reducer and the booster pump are started, the spray pipe and the flat slide rod can automatically and bidirectionally move through the limit switches, simultaneously, the atomizing nozzle of the spray pipe can automatically and continuously spray high-pressure atomized water onto the surface of the concrete, the curing coverage area is large, vehicles passing in a curing range is not affected, the self-moving spray curing device is reasonable in structural design, the tunnel secondary lining concrete self-moving spraying maintenance device meets the quality safety requirement.
Description
Technical Field
The utility model relates to a two lining concrete curing means in tunnel specifically are two lining concrete self-propelled removal spraying curing means in tunnel belongs to road bridge engineering field.
Background
Along with the rapid development of national infrastructure, stricter requirements are provided for the quality and production safety of road and bridge construction, the automation degree of construction equipment is more and more strict, particularly, the requirement for the quality of concrete in tunnel construction is higher, secondary lining concrete can carry out chemical reaction after being cast for 12 hours and demoulded, and the concrete generates heat after being subjected to hydration reaction for seven days, so that the strength and quality of the secondary lining concrete can be more effectively improved by carrying out effective water spraying maintenance treatment on the secondary lining concrete.
At present, the curing of the two-lining concrete in the tunnel is generally carried out by manually spraying and curing the concrete by using a water pipe, namely, a constructor holds the water pipe to directly spray and cure the concrete surface, and the constructor pulls the water pipe to walk in the tunnel due to the higher inner wall of the tunnel, so that other construction vehicles are influenced to pass, the spraying and curing are not uniform, and the potential safety hazard of walking exists; the other one is to adopt portable maintenance support to maintain, namely several portal connect into the rack, the layering is equipped with a plurality of shower nozzles on the rack, lay the rail below the rack, whole rack moves on the rail and sprays the maintenance, but because the installation removes the rail and blocks the accuse requirement higher to width size card, if the installation is fixed not good, make the rack derail very easily, and block the rail and influence the construction operation progress, can also disturb the current of other construction vehicles when moving on the rail of walking, influence the construction progress, reduce work efficiency, an easy operation, energy-conserving efficient tunnel two lining concrete automatic maintenance device has not yet been seen in the existing market.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the problem that two lining concrete curing in present tunnel exists to disclose a two lining concrete self-propelled removal spraying curing means in tunnel.
The device comprises a movable portal frame, a smooth sleeve, a driving speed reducer, a driving gear, a winding plate, a high-pressure water pipe, a water supply hose, a limit switch, a flat slide bar, a displacement rack, a support column, a water spray pipe, a plurality of atomizing nozzles, a water supply hose, a booster pump, a water storage tank and a booster pump, wherein the smooth sleeve is fixed on the movable portal frame, the driving gear is connected with the output end of the driving speed reducer, the winding plate is respectively installed at two ends of the smooth sleeve, the high-pressure water pipe is connected with one end of the central water inlet of the winding plate, the water supply hose is connected with the other end of the central water inlet of the winding plate and is wound on the winding plate, the limit switch is respectively fixed at two ends of the smooth sleeve, the.
The utility model discloses when two lining concrete curing in the tunnel, only need open the switch of intaking of storage water tank, start drive speed reducer and booster pump, the spray pipe at both ends just can control both way movement by oneself with smooth pole, the atomizing nozzle of spray pipe outer fringe can automatic spout high pressure atomized water in succession to two lining concrete surface simultaneously, the maintenance coverage area is big, the current not influenced of vehicle in the maintenance scope, structural design is reasonable, the security performance is high, and the stability can be strong, the efficiency of construction is high, the flexible operation is light, construction operation personnel low in labor strength, it is high to automatic one-tenth, reach the two lining concrete self-propelled spray curing means that moves in the tunnel that accords with quality safety requirement.
