The connection between plastic manhole and pipeline is also very orderly. I will start with the connection order, connection considerations and? The installation of the shaft is briefly described, and some tips are shared with you.
Figure 2: Straight-through well
Firstly, the installation sequence of the connection between the inspection well seat and the pipeline is introduced: the installation should start from the upstream section of the household connection pipe, and be installed in the order of well → pipe → well → pipe, and gradually extend to the downstream branch pipe and main pipe.
Matters needing attention in the connection construction of Jing Zuo and pipeline include: when bonding socket, glue must not leak; Rubber sealing ring interface, shall not leak aprons or aprons placed in torsion dislocation, aprons of various specifications shall not be confused.
Requirements for reducing diameter: the connection between Jing Zuo and inlet and outlet pipes needs to be reduced in diameter, and reducing joints are adopted. When the diameter of the inlet pipe is smaller than that of the Jing Zuo interface, the top of the pipe should be butted. When the interface of Jing Zuo discharge pipe is larger than the downstream pipe, the inner bottom of the pipe should be butted.
Wellbore installation: the length of the wellbore should be the height from the bottom of the socket connecting the Jing Zuo wellbore to the design ground minus the net distance from the wellbore project to the ground. When it is difficult to accurately determine the elevation of the ground or pavement, the length of the wellbore can be reserved appropriately. When important official inserts Zuo Jing, it should be vertical. When installing the shaft sealing ring, the position of the apron should not be twisted and misplaced.
