Prefabricated foundation ring beam prefabrication method and construction method of storage tank using prefabricated foundation ring beam

Abstract

The invention discloses a prefabricated foundation ring beam prefabrication method and a construction method of a storage tank using a prefabricated foundation ring beam. The preparation processes ofthe prefabricated foundation ring beam includes the steps that measuring and line laying are conducted, a prefabricated part bottom die is laid, a positioning stirrup is mounted, sealing dies at bothends of an anchored prefabricated part are mounted, a horizontal circumferential reinforcement bar in mounted, a vertical stirrup is bundled and fastened, an embedded piece is mounted, vertical steeldies are mounted on the inside and outside of the prefabricated part, concrete pouring is conducted, curing is conducted, and die removal is conducted. Construction processes of a tank body using theprefabricated foundation ring beam include the steps that engineering positioning and line laying are conducted, a ring wall prefabricated part is prefabricated, a foundation trench is excavated, a cushion layer is subjected to concrete pouring, the prefabricated ring wall and the prefabricated part are transported, the prefabricated ring wall and the prefabricated part are assembled and calibrated, the ring wall prefabricated part is in wet connection, graded sand and stone backfill of a tank core is conducted, sand cushion layer backfill is conducted, asphalt sand is laid, acceptance check is conducted. The standardization of production and the continuity of the construction processes can be realized, the quality of structures is improved, the construction period is shortened, the impacts of weather and labor on the construction quality are reduced, and pollution of on-site construction is reduced.

Description

technical field [0001] The invention belongs to the field of oil depot structures, and in particular relates to a method for prefabricating an assembled foundation ring beam and a storage tank construction method using the product. Background technique [0002] In the construction of the current oil depot project, the construction of the foundation ring beam has always been cast-in-situ. The traditional process is: scaffolding erection-reinforcement binding-formwork support-formwork-concrete pouring-formwork removal, in which both scaffolding and formwork need Set along the entire length of the foundation ring beam, the workload is heavy and the construction period is long. Since the foundation ring beam of the tank is circular, and the circumference of the ring beam is relatively large, it is necessary to set several positioning piles along the circumference during on-site construction to ensure the position of the formwork during installation, which is time-consuming and l...
