Production technology of anti-corrosion prefabricated reinforced concrete inspection well

Abstract

The invention discloses a production technology of an anti-corrosion prefabricated reinforced concrete inspection well, which comprises the steps of sequentially cleaning inner and outer molds of the inspection well, coating the inner and outer molds with mold release agents, fabricating and inspecting reinforced skeletons in the anti-corrosion concrete inspection well, filling the inner and outer molds with the reinforced skeletons in the anti-corrosion concrete inspection well, mixing slag powder, coal ash, sand, stone, an excitant, a special additive and water to form anti-corrosion concrete, pouring the anti-corrosion concrete in the inner and outer molds, forming the anti-corrosion concrete by pouring via a hanging roll technology, a vibrating technology and a mandrel vibrating technology, placing the anti-corrosion concrete formed by pouring, and the inner and outer molds into a station, allowing the anti-corrosion concrete formed by pouring, and the inner and outer molds to be subjected to steam-cured treatment, demolding, and transferring the solidified anti-corrosion concrete inspection well to a storage yard for natural curing. The inspection well produced by the technology is high in strength, good in permeability resistance, energy-saving and environment-friendly, and can achieve factory prefabrication, and the service life of the inspection well is longer than that of the common concrete inspection well.

Description

technical field [0001] The invention relates to the field of inspection wells for urban drainage engineering, in particular to a production process for corrosion-resistant prefabricated reinforced concrete inspection wells. Background technique [0002] The existing urban drainage engineering pipelines all adopt buried laying, including rainwater pipelines, domestic sewage pipelines and industrial sewage pipelines. It is necessary to set up inspection wells every tens of meters along the pipeline to implement the connection between different pipelines and the dredging of (sewage) mud. Inspection wells are an essential and important part of urban drainage (sewage) water engineering pipelines. [0003] At present, the inspection wells used in urban drainage engineering pipelines include red brick masonry, ordinary concrete cast-in-place, ordinary concrete prefabricated and plastic inspection wells. Red brick masonry inspection wells have low strength and poor impermeability,...

AI Technical Summary

Problems solved by technology

Red brick masonry inspection wells have low strength and poor impermeability, and are banned; prefabricated concrete brick masonry inspection wells are limited by the specifications of inspection wells, and the on-site construction takes a long time, requiring a large amount of mortar to be mixed on site, polluting the environment; Poured ordinary concrete inspection wells are generally suitable for drainage projects with particularly large diameters, which have a long construction period and pollute the environment; ordinary prefabricated concrete inspection wells are not suitable for pipeline projects with corrosive fluids, and have poor durability; plastic inspection wells have poor rigidity and cost High, not suitable for heavy-duty road use
