Prefabrication method of prefabricated foundation ring beam and storage tank construction method using the product

Abstract

The invention discloses a method for prefabricating an assembled foundation ring beam and a storage tank construction method using the product. The preparation process of the prefabricated foundation ring beam includes measuring and setting out the line, laying the bottom mold of the prefabricated component, installing the positioning stirrup, installing the sealing mold at both ends of the anchoring prefabricated component, installing the horizontal circular steel bar, binding the vertical stirrup firmly, installing the pre-embedded Components, installation of inner and outer vertical steel forms of prefabricated components, concrete pouring, maintenance, and formwork removal. Application, the tank construction process of the prefabricated foundation ring beam, including project positioning and setting out, prefabrication of ring wall prefabricated components, foundation trench excavation, cushion concrete pouring, prefabricated ring wall prefabricated components reverse transportation, prefabricated ring wall prefabricated components assembly Calibration, wet connection of ring wall prefabricated components, tank core graded sand and gravel backfill, sand cushion backfill, asphalt sand laying, acceptance and other steps. The invention can realize the standardization of products and the continuity of the construction process, improve the quality of the structures, shorten the construction period, reduce the influence of weather and labor on the construction quality, and reduce the construction pollution on site.

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...
