Embodiment

[0039] After the mold trolley of the HSL48 / 60MD segment flow production line is driven out of the steaming room, the trolley is moved to the pouring line through the ejection tunnel, and after the demoulding station stops completely, the workers at the demoulding station remove the The demoulding operation of the components is carried out in sequence, and then the components are lifted from the mold and placed in the designated temporary storage area for the components. After reaching the strength, it will be lifted and transported to the storage area for storage. After the component is demolded, the workers at the station check the mold cleaning condition, use special tools to evenly spray the mold release agent on the inner surface of the mold, then hoist and place the reinforcement cage and embedded parts, and check and close the upper cover of the mold. Then the trolley brings the mold into the concrete pouring vibration room, and the operator connects the power device req...

Abstract

The invention relates to a process for prefabricating windproof open hole components in a circular production line, including mold steam curing, demoulding operations, cooling and secondary steam curing, placement of steel cages and embedded parts, concrete pouring, vibration supplementation, initial plastering, and static stop And cleaning the mold, second plastering, curing in the steam curing area, and so on, the prefabrication work of the windproof open hole components will be completed in a cycle; marking and storage; the finished product will leave the factory. This process solves the problems of low work efficiency and difficult quality control of the prefabrication of windproof open tunnel components in windy areas. It has the characteristics of ensuring work efficiency, shortening the construction period, and easy quality control, and effectively reduces the overall construction cost.

Description

technical field [0001] The invention relates to a process for prefabricating windproof open hole components on a circular production line. technical background [0002] During the construction of the railway, according to the actual working conditions, the prefabricated open-hole structure is adopted in the local wind area for wind protection. The durability of the windproof open tunnel segment structure is designed according to the service life of 100 years. It adopts an arched structure. The production goes through the forming process of steel bar production, steel mold preparation, concrete pouring, demoulding, and maintenance. After the formed components are assembled on site, an "artificial tunnel" will be formed, which will minimize the impact of wind disasters in this area on railway operations and ensure the safe, fast and normal operation of trains. [0003] Due to the large number of prefabricated components of the windproof open tunnel, the construction environme...
