Composite arch covering for large cesspool

Abstract

The invention discloses a composite arch cover of a large cesspool, comprises an arch shell arranged above the cesspool, a skeleton (2) arrange on both ends of the sewage tank and a sealing plate installed on the skeleton (2), the arc housing comprises a single arc housing arranged side by side in a plurality of sections, adjacent to the single arc housing connected by rubber gaskets and bolts, the single arc housing comprising two semi-arc housings (1), through which the two semi-arc housings (1) are connected by rubber gaskets and bolts. The composite arch cover of the large cesspool is fixed on the concrete plane of the cesspool by bolts, and can be applied to the cesspool with wider span, wider width and wider application range than the ordinary arch cover. At the same time, it improves the air pollution problem of the existing sewage tank and improves the ambient air quality of the sewage treatment plant office workers and the surrounding areas.

Description

technical field [0001] The invention relates to the technical field of sewage pools, in particular to a composite material arched cover for a large sewage pool. Background technique [0002] With the continuous development of the economy, the country pays more and more attention to environmental protection. The sewage pools of the existing large-scale urban domestic sewage treatment plants are mostly open-air, and the domestic sewage of residents is treated through multiple processes, but some odorous substances during the treatment process are not collected. , volatile and directly discharged into the air, causing a certain impact on the surrounding environment. [0003] Most of the sewage treatment plants are large sewage pools. The width of the sewage pools used by the existing FRP arched covers is small and cannot be applied to larger sewage pools, generally within 5-10 meters. The existing composite material arched covers can only be used in Sewage ponds with a width o...

Problems solved by technology

[0003] Most of the sewage treatment plants are large sewage pools. The width of the sewage pools used by the existing FRP arched covers is small and cannot be applied to larger sewage pools, generally within 5-10 meters. The existing composite material arched covers can only be used in Sewage ponds with a width of less than 10m; the arched covers of the existing sewage pools are mostly reinforced with long bars, and the arched cover body structure is rarely used to achieve the required rigidity and cover the sewage pool with a large span; some of the existing arched cover body structures use The wave shape is used to enhance the rigidity of the body, but the arc radius of the wave shape is relatively large, and the overall stiffness of the arched cover is not good, so it cannot cover the sewage pool in a wide width;
