Example.And these embodiments are to provide, so that the present invention is fully and completely, and will fully convey the scope of the invention to this
The those of ordinary skill in field.
As shown in figure 1, invention provides a kind of bar connecting grout sleeve or the repairing when being in the milk not enough of device
Device is mended, the repair apparatus include the patching material input channel 1 and patching material efferent duct in insertion grout sleeve or device
Road 2；Wherein, the port in patching material input channel 1 and the insertion grout sleeve of patching material output channel 2 or device 3 is set
In the top of steam vent 4 of grout sleeve or device, it is to avoid when prefabricated components are installed, grouting material floods patching material input channel
Not yet, line clogging is caused, cannot be subsequently repaired.
Between port in the insertion grout sleeve or device 3 of patching material input channel 1 and patching material output channel 2
Keep a setpoint distance.Setpoint distance is not less than 0.1cm；Patching material input channel 1 inserts the end in grout sleeve or device 3
Mouth inserts the port in grout sleeve or device 3 less than patching material output channel 2；It is defeated for avoiding pipeline opening at a distance of too near
The patching material for entering directly is flowed out under the drive of air-flow by patching material output channel, causes false repairing to complete proterties.
Repaiied in sleeve the port of patching material input channel 1 and patching material output channel 3 outside grout sleeve or device 3
