Description
Technical field
The invention belongs to electric power project engineering fields, and in particular to a kind of bracket blocked for cable.
Background technique
Cable duct bank is cable laying pipeline, and material is generally cement, iron pipe or MPP pipe etc., and cable duct bank mouth is general
It needs to block, if do not blocked, once some comb leakage water, just easily leads to ponding and involves along comb hole to other comb wells
It is interior, then deteriorate the running environment of cable, so that medial head is soaked for a long time, greatly reduce the service life of cable mid head.Currently,
The comb hole of underground switching station is mostly used grout off, but cement is rigid material, once expanding with heat and contract with cold, will be cracked, and
Grout off is in irregular shape inside comb, and resistance to pressure is poor, in real work, rainwater often occurs and flows backward into distribution
The case where room, seriously threatens the safe operation of the person, equipment, power grid.
Chinese invention application (application number 201310398820.6) discloses a kind of cable duct bank concrete pack expansion joint
Structure and its construction method, including concrete pack, cable duct bank, the whole disjunction at expansion joint of concrete pack arrangement of reinforcement, stretch
Filling plate is equipped at contracting seam, aperture is total to cable duct bank and passes through on filling plate, and the filling every side of plate is small compared with concrete pack size, by wrapping
Seal inner concrete and fill board group at groove sealing filling, reinforcing bar is had connected in concrete storm wind, connection reinforcing bar is another
End is the free end of outer case sleeve, and casing is blocked in disconnected reinforcing bar inserting end using stopper, at the device expansion joint
Reinforcing bar is connected, one end is cased with casing, free extension may be implemented, and concrete deformation is effectively relieved and breaks to electric power and communication comb
It is bad, play good protective value.
But the apparatus structure is complicated, work progress is excessively cumbersome, seriously reduces working efficiency, and due to constructing not
Standard, frequently results in that cable duct bank nozzle is irregular, concrete and filling board group at groove clogged with sealing compound, connect
Reinforcing bar inserting end is blocked using stopper, and since the elasticity of sealing compound and stopper is insufficient, place irregular for nozzle holds
Easily poorly sealed close, while fever is easy when cable work, sealing position is easy expansion, the elasticity of sealing compound and stopper compared with
It is small, it is not easy to make up gap caused by the expansion of cable duct bank in time, will lead to poorly sealed problem.
Summary of the invention
The purpose of the present invention is: it is intended to provide a kind of bracket blocked for cable, blocks dress for solving existing cable
