Description
Technical field
The present invention relates to civil engineering gap plugging technical field, more particularly to a kind of sleeve pipe gap plugging device.The present invention is also
It is related to a kind of sleeve pipe gap plugging method.
Background technology
During civil engineering construction, as shown in Figure 1 in the pond of reinforced concrete structure, can be on pool wall one
As can embedded wall penetration sleeve pipe 02, the pipeline 01 for penetrating pond inside Inlet and outlet water, sleeve pipe 02 is to be embedded in concrete structure
Metal section on the wall of side, forms a hole, and for penetrating pipeline 01, the internal diameter of sleeve pipe 02 is typically compared outside the pipeline 01 for penetrating
Footpath about 50mm.Sometimes, when sleeve pipe 02 needs the pipeline 01 of threading flange, the gap 03 of ultra-wide occurs after penetrating, flange
It is different that width presses pipe diameter, generally 50-100mm, and now sleeve pipe 02 is likely to be breached with the width in the gap 03 of pipeline 01
150mm。
As shown in Fig. 2 for the sleeve pipe gap plugging of ultra-wide, traditional method is using dry cement mortar/coagulation
Soil+asbestos cement closure.Specifically, clogging dry cement mortar/concrete during construction first, dry cement mortar is formed
Layer 05, maintenance is successively clogged asbestos cement and beats closely knit again after 7 days, form asbestos cement layer 04.Because gap 03 is wide, fill out
Dry cement mortar/the concrete of plug will play a part of fixed -piping as packing material, it is ensured that it is not rocked, it is necessary to etc.
Asbestos cement is clogged on mortar after intensity, otherwise when asbestos cement is beaten in tamping, mortar asbestos cement if loosening
Tamping operation cannot be carried out.
However, because dry cement mortar hardness mortar cannot be vibrated, density is poor；Mortar/concrete
Adhesive strength is low, and it is poor with the bonding firmness of pipeline 01, sleeve pipe 02, is likely to occur under the external force effect of tamping asbestos cement
The overall loosening of screed.When gap is wider, the point contacting surface product of tack chisel is small, and the point for having consolidated may be consolidated on periphery
When occur tilt loosening problem and influence packing.When pipe vibration, rigid material is unable to adaptive deformation and material is innate
The characteristic of shrinkage cracking, for a long time using especially when sleeve pipe gap width is excessive, Material shrinkage amount is bigger, causes to cover pipe seam
