Inspection wells are built with plastic drainage pipes buried in residential areas (residential areas, public buildings, factories, etc.) whose outer diameter is not more than 800mm and buried depth is not more than 6m. They are generally located at the junction, turning point, change of pipe diameter or gradient, drop point, etc. In order to facilitate regular inspection, cleaning and dredging, or plastic integral injection moulding for downhole operation and inspection, or bricklaying. A well-shaped structure.
Plastic injection inspection wells refer to the one-time injection molding of the main wellbore part of the inspection wells. The wellbore socket adopts 360 degree ring bearing platform, the wellbore and the bottom of the wellbore adopt reticulated reinforcing bars, and each socket socket adopts ring reinforcing bars design. According to the number and angle of nozzles, there are starting wellbore, through wellbore, 45 degree elbow wellbore, three-way wellbore, four-way wellbore and so on. In order to adapt to various drainage conditions, plastic inspection wells are equipped with variable diameter joints, confluence joints, wellbore multi-joints and other plastic integral injection moulding accessories. To ensure the fluency and sealing of the whole drainage system.
