Spherical silo construction method

Abstract

The invention discloses a spherical silo construction method, and relates to the technical field of building construction. The construction method comprises the steps of a step of ring foundation construction, a step of membrane body laying, and a step of painting a polyurethane coating layer in the membrane body. Between the step of ring foundation construction and the step of membrane body laying, the following steps still exist: measuring the positions of preformed holes, and marking the positions on the ground occupied by the ring foundation, after the step of the membrane body laying is completed, the projections of the positions of the preformed holes which are marked on the ground occupied by the ring foundation are projected to the membrane body, and the projection points on the membrane body are marked accordingly. In the step of painting the polyurethane coating layer in the membrane body, the moulds of the preformed holes are placed at the marked points, and painted with the polyurethane layer and / or a concrete layer, after all the painting work is finished, the moulds of the preformed holes are removed, thus the holes are formed above the silo wall or silo cap of the spherical silo in a manner that the integrity of the polyurethane layer and the concrete layer is not undermined. Not only the material is saved, but also the integrity of the polyurethane layer and the concrete layer is not undermined, the overall stress condition is more uniform, the silo produced by the method is more sturdy and durable, and the service life is longer.

Description

technical field [0001] The invention relates to a construction method for a spherical warehouse, which belongs to the technical field of building construction. Background technique [0002] The spherical thin-shell concrete storage silo is the ideal storage silo with the largest storage capacity per unit area. It has a beautiful appearance, is economical and environmentally friendly; it has a high filling rate and can use the space most efficiently; it has a reasonable structure and the highest pressure on the silo body (the maximum load-bearing capacity on the top of the silo) 500t), anti-corrosion, windproof, rainproof, shockproof, sturdy and durable; fully enclosed, well preventing dust pollution; good temperature insulation and moisture resistance, and will not form water vapor. The shell can be applied to soil 50 ℃. Due to the adoption of the advanced air film support construction method, the shell construction is almost not affected by the weather, which greatly short...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in the prior art, the opening of the subsequent warehouse wall or warehouse roof hole is carried out after the overall construction is completed, which not only wastes materials, but also destroys the integrity of the polyurethane layer and the concrete layer, and then proposes A construction method for spherical warehouse with better integrity and more material saving
