Supporting device in backfilling shaft of plastic inspection well and construction method

ZHU YUXUAN / YUAN YINGJUN / JI YIFAN

The invention discloses a plastic inspection well backfilling shaft inner supporting device which comprises a protective shell, the protective shell is arranged on a plane, an adjusting unit and a supporting unit are arranged on the protective shell, the adjusting unit is used for driving the supporting unit to move and deform and supporting a well wall, and the supporting unit is used for supporting the well wall; the supporting unit and the adjusting unit are locally connected, the supporting unit is adjusted by the adjusting unit to extend towards the well wall, the adjusting unit comprises a power structure and a transmission structure which are arranged on the protective shell, and the power structure is used for driving the transmission structure to control the supporting unit. According to the inner supporting device for the backfill shaft of the plastic inspection well, the hand wheel is rotated to drive the lead screw to move up and down, and then the supporting rod is driven to contract or expand, so that the purpose of generating lateral supporting force is achieved, the side wall of the plastic shaft can be effectively protected against deformation caused by non-standard construction, and the construction quality of a rainwater and sewage pipeline is greatly improved.

本发明公开了一种塑料检查井回填井筒内支撑装置，包括：保护外壳，所述保护外壳设在一平面上，所述保护外壳上设置有调节单元和支撑单元，所述调节单元用于带动所述支撑单元移动变形，对井壁支撑，所述支撑单元和所述调节单元局部连接，所述支撑单元被所述调节单元调动向井壁延伸，所述调节单元包括设置在所述保护外壳上的动力结构和传动结构，所述动力结构用于带动所述传动结构控制于所述支撑单元。该塑料检查井回填井筒内支撑装置，通过转动手轮，带动丝杆上下移动，进而带动撑杆收缩或扩张，以达到产生侧向支撑力的目的，能够有效保护塑料井筒侧壁不会因不规范施工产生形变，大幅提升了雨污水管道施工质量。
