Description

Inflatable shape-adjustable composite maintenance tarpaulin Technical Field The utility model relates to the technical field of concrete curing devices. More particularly, the utility model relates to an inflatable shape-adjusting composite maintenance tarpaulin. Background In the construction process of a large amount of concrete structures, the elevation maintenance technology is always an industrial technical problem for limiting engineering quality. In the early stage of the hydration reaction of the freshly mixed concrete, due to unstable thermal performance of a surface coating layer and insufficient efficiency of a humidity maintaining system, plastic shrinkage cracks and temperature stress cracks are extremely easy to be caused, so that the durability defects of structural body compressive strength growth retardation, excessive carbonization depth and the like are caused, and obvious risks are formed for construction quality control and progress management. The existing elevation curing process mainly comprises a geotextile covering and combining technical systems such as intermittent water spraying, movable constant temperature and humidity curing barn, an atomization spraying system, film-forming curing agent application and the like. The high-density fiber cloth is matched with the timing water supply to be still in a conventional operation mode, but has the technical defects of low work efficiency index, large fluctuation of heat conduction coefficient, high discreteness of humidity control and the like, and is more easy to generate surface temperature gradient exceeding standard and local shrinkage cracks under the negative temperature alternating working condition. Although the maintenance bin system can maintain stable microenvironment (the temperature control precision is +/-3 ℃ and the humidity is more than or equal to 95 percent), the problems of overhigh equipment amortization cost, poor working face adaptability and the like exist. When the atomization system is applied in a cold region, the atomization system is limited by the ambient temperature (the freezing risk rate is more than or equal to 60% at the temperature of T <5 ℃), and the atomization system has poor sealing effect and large mist loss in a high-altitude environment. The film-forming material has insufficient extreme weather resistance (the retention rate of storm flushing is less than or equal to 70 percent, and the film-forming material fails after 3 times of freeze thawing cycles at 15 ℃ below zero). Thus, the prior art lacks a special handling scheme for extreme thermal conditions (solar temperature difference > 20 ℃ or continuous high temperature >40 ℃), resulting in limited process application area. Disclosure of utility model It is an object of the present utility model to solve at least the above problems and to provide at least the advantages to be described later. To achieve these objects and other advantages and in accordance with the purpose of the utility model, there is provided an inflatable shape-adjusting composite curing tarpaulin comprising a fireproof surface layer, a heat insulation layer, an inflatable shape-adjusting layer, an anti-stabbing layer and a moisture-keeping substrate layer laminated and compounded by adhesive sequentially from top to bottom, wherein a plurality of air chambers are arranged in the inflatable shape-adjusting layer, each air chamber is communicated sequentially through a one-way valve, the air chambers at two ends are respectively provided with an air inlet interface and an air outlet interface, and valves are arranged at the air inlet interface and the air outlet interface. Preferably, the fireproof surface layer is made of silicone rubber glass fiber cloth or aluminum foil composite glass fiber cloth, and the thickness of the fireproof surface layer is 0.8-1.5mm. Preferably, the heat insulation layer is an aluminum silicate needled blanket with the thickness of 5-10mm. Preferably, the inflatable shape-adjusting layer is a TPU air bag, the inside of the inflatable shape-adjusting layer is divided into a plurality of air chambers, and the area of each air chamber is not more than 0.3m < 2 >.
