Specific embodiment
The present invention will be further described with preferred embodiment with reference to the accompanying drawing.
Referring to shown in Fig. 1 to 4, a kind of end extension slip casting steel tube for soil-nail involved in the present embodiment, including both ends are not sealed
The main pipe 1 closed, main pipe 1 have head end 11 and aft end 12, and the head end 11 is connected with to be set with 1 coaxial line of main pipe
The cylindrical, hollow shell 2 set, cylindrical, hollow shell 2 has shell upper surface 21 and shell lower end surface 22, on the shell
End face 21 offers the feed inlet 211 connecting with head end 11, and the shell lower end surface 22 offers several discharge ports 221, institute
It states cylindrical, hollow shell 2 and is equipped with the end Grouting Pipe 3 that and lid equal with 221 quantity of discharge port closes each discharge port 221, end
Grouting Pipe 3 is identical as the extending direction of the main pipe 1, and the end cap of the end Grouting Pipe 3 is equipped with cone cap 31, the end
It is laid with slurries hole 32 on the wall surface of Grouting Pipe 3, is arranged with the partition 4 close to aft end 12 on the main pipe 1, on partition 4
Equipped with side identical with 1 extending direction of main pipe Grouting Pipe 5, it is also provided on the partition 4 for 5 pulp of side Grouting Pipe
Side material mouth 41.
In the present embodiment, firstly, being punched by existing punch device in the wall side for needing to squeeze into fixed soil nailing, hole
In the cylindrical hole that one end is connected to outside, hole internal diameter is adapted to substantially with the outer diameter of cylindrical, hollow shell 2, then fetches steel pipe soil
Nail, head end 11 is filled in the cylindrical hole on wall, and aft end 12 is embedded in the cylindrical hole on wall, is held
Portion's Grouting Pipe 3 is driven into soil, then is giving 1 head end of main pipe 11 side slip casting, and slurries are along main pipe 1 and cylindrical, hollow
Shell 2 flows into end Grouting Pipe 3, oozes out through slurries hole 32, and the slurries and soil of exudation are firmly combined；Giving side slip casting again
5 slip casting of pipe, slurries fill gap between cylindrical, hollow shell 2 and partition 4, so that slurries are also firmly combined with soil at this,
To complete the laying of steel tube for soil-nail.
