Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

The split type drainage inspection well shown in the figures 1-4 comprises a well cover 1, a shaft 2, a supporting plate 3 and a rubber gasket 4; the well lid 1 and the shaft 2 are both circular and the shaft 2 is preferably a prefabricated part. The well lid 1 covers the upper end of the shaft 2, and the inner wall of the well lid 1 is provided with an annular groove 5; the rubber gasket 4 is annular, the outer side end of the rubber gasket 4 is positioned in the groove 5, and the inner side end of the rubber gasket 4 is positioned between the well lid 1 and the shaft 2; the supporting plate 3 is annularly arranged at the outer side end of the shaft 2 and keeps a distance with the shaft; the supporting plate 3 is connected with the well cover 1 through a connecting bolt 6; the well lid 1, the shaft 2 and the rubber gasket 4 are connected through a connecting screw 7.

In order to facilitate the installation and the disassembly and replacement of the rubber gasket 4, the annular rubber gasket 4 is formed by connecting a plurality of arc-shaped rubber strips end to end, and each arc-shaped rubber strip is provided with at least one through hole matched with the connecting screw 7. The mode of decomposing traditional annular packing ring into a plurality of arc rubber strips not only is convenient for rubber packing ring 4's installation, makes rubber packing ring 4 atress dispersion moreover, prolongs 4 life of rubber packing ring. When the sinking road surface is repaired, only the rubber strip at the corresponding side needs to be replaced.
