Connecting structure of prefabricated assembly type drain valve well and construction technology
The invention relates to the technical field of underground pipeline construction, and provides a connecting structure and a construction process of a prefabricated assembly type drain valve well, which are used for fixing a cast iron pipe and a well body, the connecting structure comprises a connecting seat arranged on the well body and integrally formed with the well body, and the cast iron pipe penetrates through a through hole formed in the center of the connecting seat and extends into an inner cavity of the well body; a gap is formed between the cast iron pipe and the through hole; the gap is filled with a pouring body, and the side, close to the outside of the gap, of the pouring body is coated with a sealing layer. The variable-diameter body is arranged on the peripheral side of the cast iron pipe and used for forming a variable-diameter interval along the peripheral side of the cast iron pipe, the diameter of the variable-diameter interval is correspondingly matched with the inner diameter of the through hole, and the variable-diameter body is wrapped with the pouring body; the supporting body is fixedly connected to the inner wall face of the through hole, and when the cast iron pipe penetrates through the through hole, the reducing body abuts against the supporting body. The connection sealing performance of the drain valve well and the cast iron pipe can be enhanced, and the structural stability of the assembly type drain valve well is improved.
本发明涉及地下管道施工技术领域，提供一种预制装配式排水阀井的连接结构及施工工艺，用于将铸铁管与井体固定，包括：连接座，设置在井体上、与井体一体成型，铸铁管贯穿连接座中心开设的通孔并伸入井体内腔，铸铁管与通孔之间设置有间隙；其中，间隙内填充有浇筑体，浇筑体靠近间隙外的一侧涂覆有密封层；变径体，布置在铸铁管外周侧，用于沿铸铁管外周侧形成变径区间，变径区间的直径与通孔的内径对应匹配，且浇筑体包覆在变径体外；支撑体，固接在通孔内壁面，当铸铁管贯穿在通孔时，变径体与支撑体相抵。能够实现增强排水阀井与铸铁管的连接密封性，并提高装配式排水阀井的结构稳定性。
