Description
Technical field
The utility model relates to a kind of inside water proof structures of cast-in-place inspection shaft comb interface.
Background technique
Cast-in-situ steel reinforced concrete inspection shaft is electric power, communicates a kind of structures that pipe engineering generallys use.These are checked
Well largely needs to carry out waterproof.If occurring ponding in inspection shaft, the immersions such as cable and wire in water, do not only maintain inconvenience,
And it is possible to bring security risk to operation power.
Currently, the interface mode of common electric power, communication comb and inspection shaft uses cement mortar, water swelling rubber ring
Or water string etc..However, this way waterproof effect is poor.And this water proof structure is generally located in the borehole wall, once it is anti-
Water disabler is difficult to repair.
