Detailed Description
The utility model is described in further detail with reference to the figures and specific embodiments.
As shown in the figure, the detachable water stopping device between the outgoing cable and the embedded cable sleeve of the hollow fan foundation is a water stopping device which prevents the underground water outside the foundation from permeating into the cavity area 7 inside the foundation 1 along the gap 6 after the cable 2 is installed on the embedded cable sleeve 3 of the hollow fan foundation 1 in the underground water development area.
Hollow formula fan basis 1 pre-buried cable sleeve 3 link up the basis 1 inside and outside to supply cable 2 to link up the laying of basis 1 concrete to outside from basis 1 inside.
As shown in fig. 2, the flexible hollow rubber ring 4 is annular and is embedded into a gap 6 between the embedded cable sleeve 3 and the cable 2, and the installation position of the flexible hollow rubber ring 4 inside the foundation 1 is aligned with the end of the embedded cable sleeve 3.
As shown in fig. 3, the flexible hollow rubber ring 4 has a circular section in the shape of a drum, a middle part in the shape of a hollow cavity 9, and a gap 8 between the flexible hollow rubber ring 4 and the embedded cable sleeve 3 is 4 mm.
As shown in fig. 3, a top annular steel plate 10 with the thickness of about 4 mm is installed on the upper plane of the section of the drum shape, the inner side of the circle center of the annular steel plate is flush with the flexible hollow rubber ring 4, and the outer side of the circle center of the annular steel plate covers the outer end area of the embedded cable sleeve 3; a bottom annular steel plate 11 with the thickness of about 4 mm is arranged on the lower plane of the section of the round drum shape, and both sides of the bottom annular steel plate are flush with the flexible hollow rubber ring 4.
As shown in fig. 3 and 4, the bottom annular steel plate 11 is welded to the turnbuckle 5 as a whole, the upper end head screw section 12 is about 20 mm long, and a turnbuckle 13 and a gasket 14 are used in cooperation.
