Description

Technical Field

[0001] The invention relates to the technical field of high pier construction, in particular to high pier steam maintenance equipment. Background Art

[0002] With the rapid development of my country's transportation industry, highway construction has gradually extended to mountainous and hilly areas. Due to the restrictions of terrain conditions, highway construction in these areas often needs to cross deep gullies and canyons, resulting in an increasing number of high-pier bridges. In order to ensure sufficient support strength and longer service life, bridge piers are generally cast in concrete, which can effectively prevent rust, penetration and deformation, and provide protection for bridge safety; however, after the construction of the concrete structure is completed, a period of maintenance is required. Usually, maintenance needs to be started 12-18 hours after the pier concrete is cast, and the maintenance time lasts about 3-4 weeks to ensure the normal hardening and strength growth of the pier.

[0003] In addition to covering and sprinkling water on the piers after construction, the maintenance method also requires heating maintenance, constant temperature maintenance, and cooling watering in a wet state. The process is relatively cumbersome and time-consuming. Existing pier concrete maintenance methods usually use spraying or film covering to keep it moist, but due to the limited absorption rate of concrete for water, it is difficult to achieve uniform spraying by spraying, which not only wastes water resources, but also has a large impact on the surface of the pier, which can easily cause the surface mud to peel off and dissolve and lose; film covering can save water and has a good water-locking and moisturizing effect, but the film exposed to the outdoors is easily damaged, and it is difficult to ensure the integrity and effectiveness of the covering.

[0004] Both of the above two methods cannot adjust and control the curing temperature, and cannot steam-cure the poured concrete in time during the construction of the high pier, which is not conducive to the effective hardening of the high pier concrete of the bridge within the predetermined time. Summary of the invention

[0005] In order to solve the deficiencies mentioned in the above-mentioned background technology, the purpose of the present invention is to provide a high pier steam curing equipment, which can perform concrete pouring on the upper side of the roller mold lifting frame while curing the high pier body demolded on the lower side of the roller mold lifting frame, so as to achieve pouring and curing at the same time, which greatly improves the efficiency of high pier construction and shortens the construction period of high piers of bridges.
