The stone of mud, sand and maximum particle diameter less than 25 millimeters after mix, loads spraying machine by a certain percentage, with compressed air by dry-mixing
Material along Pipeline transport to shower nozzle at, mix with water and is sprayed with the high speed of 40~60 meter per seconds to formation in the scope of operation.
Splash guard 500 is made up of waterproof material, is specifically as follows high molecular polymer, prevents fluid seepage, can also be pre-
Anti- gaseous volatilization.Specifically, the axis of grouting pipe 100 can be perpendicular with the plane where splash guard 500.
Two lining structures 600 refer to the structure formed during secondary lining, control the deformation of earth's surface and surface buildingses.Specifically
It can be main material by commerical ready-mixed concrete, be by cement, aggregate, water and the additive mixed as needed, mineral admixture
Etc. component according to a certain percentage, sold in mixing plant after metering, mixing and use transport vehicle, be transported to makes at the appointed time
With the concrete mix in place.
The grouting pipe 100 of the utility model embodiment offer and the operation principle of filling system are：
Just branch structure 400 is first built in the position that need to be constructed, then covers one layer of splash guard on the surface of first branch structure 400
500, then, the first end 111 of grouting pipe 100 is in contact with the surface of splash guard 500, or the of grouting pipe 100
One end 111 and the surface of splash guard 500 have a certain distance.After grouting pipe 100 is set, at connection sleeve pipe 120
Plug 200 as shown in Figure 3 is connected, and two lining structures 600 are irrigated in the region where the body 113 in grouting pipe 100, in detail
Feelings can be found in Fig. 4 and Fig. 5.After the perfusion for completing two lining structures 600, connection sleeve pipe 120 and plug 200 are exposed to two lining structures
600 surface.
Because the surface of splash guard 500 is oily material, so easily being produced between two lining structures 600 and splash guard 500
Raw gap, so as to have influence on the waterproof effect of splash guard 500, therefore, can outward winding plug 200, and at connection sleeve pipe 120
Connecting tube 300 is connected with, and connecting tube 300 is connected with slip casting backfilling mechanism, so as to be passed through successively by slip casting backfilling mechanism
Connecting tube 300, connection sleeve pipe 120 and body 113 backfill slip casting to the gap between two lining structures 600 and splash guard 500.And
And after slip casting step is backfilled, the annexation between connecting tube 300 and connection sleeve pipe 120 is released, then again by plug 200
Connection sleeve pipe 120 is blocked, prevents dust, cement etc. from entering in connection sleeve pipe 120 so as to cause to block to the grouting pipe 100.
Because grouting pipe 100 can be made up of steel material, the 100 more difficult deformation of grouting pipe of steel, two
After the completion of lining structure 600 (i.e. commerical ready-mixed concrete) pours, it can go out in plug 200 and leave mark, can easily find the position of conduit.
And slip casting backfilling mechanism to the slip casting of grouting pipe 100 pressurize when, the influence to grouting pipe 100 is smaller.And steel slip casting is led
Pipe 100 repeats utilization rate height, after slip casting backfilling operation, plug 200 can be used to be screwed in unsintered tape in connection sleeve pipe 120,
The sealing of assiatant's conduit is improved, can be with if still there is the phenomenon of percolating water at the lining structure 600 of later stage splash guard 500 and two
The grouting pipe 100 is continued through to cement injection at the gap of the lining structure 600 of splash guard 500 and two.
The grouting pipe 100 and filling system that the embodiment of the present application provides include：Pipe main body 110, connection sleeve pipe 120 and
Seal ring 130, the pipe main body 110 are hollow columnar structures, the pipe main body 110 include first end 111, the second end 112 with
And body 113, the seal ring 130 is sheathed on the surface of the body 113, and the seal ring 130 is arranged on described first
Between the end 112 of end 111 and second, the internal diameter of the connection sleeve pipe 120 is more than the external diameter of the pipe main body 110, the adapter sleeve
Pipe 120 is sheathed on the second end 112 of the pipe main body 110, and the connection sleeve pipe 120 is fixedly connected with the pipe main body 110.
Grouting operation can be performed into pipe main body 110 by connection sleeve pipe 120, so as to fill two lining structures 600 and splash guard 500 it
Between caused gap, improve splash guard 500 waterproof effect.
