2) the waterproof shutoff is carried out in the cable sleeve end of infiltration, before shutoff in the plugging material of infiltration sleeve pipe pre-buried 1～2 stainless steel tube, connect wired hose after stainless steel tube and consist of drainage tube;
3) will be connected in the infiltration collection conduit by collecting pipe from the drainage tube that each infiltration point extracts;
4) infiltration collection conduit along ground or cable testing bridge additionally arrange, be discharged at last in cesspit;
5) be provided with 2 dredge pumps in cesspit, automatically control its start-stop by liquid-level switch, need not personnel on duty.
Described waterproof plugging material adopts the solidifying sealing agent of cyanogen.
Use the device of a kind of described underground cable sleeve pipe infiltration improvement method, comprise negative well, drainage tube, collecting pipe, infiltration collection conduit and cesspit, negative well is located in 5～10 meters scopes of cable sleeve end for process of infiltration, it is dark that negative well depth ratio process points absolute altitude is wanted, drainage tube one end is located in cable sleeve, the cable sleeve end is provided with the plugging material layer, and the drainage tube other end is connected with cesspit with collecting pipe, infiltration collection conduit successively.
Described plugging material layer depth is no less than 300mm.
Be provided with dredge pump and fluid level controller in described cesspit, fluid level controller is connected in the control loop of dredge pump.
Described drainage tube is provided with valve.
Compared with prior art, the invention has the beneficial effects as follows: solved the hidden danger that ground water seepage that the cable sleeve corrosion causes floods cable trench; Can timely emptying ponding, avoid cable to duck in drink for a long time and cause cable bad and electric leakage, realize Auto-drainage, need not personnel's inspection ponding on duty and drainage situation, guarantee to realize safe spot check.
