Detailed description of the invention
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described:
As shown in Figure 3, built-in injection hole sealing device of the present utility model, plug after comprising plug before bag type paste, bag type paste, connects the interlude pvc pipe 12 of plug after plug and bag type paste before bag type paste; Before described bag type paste plug comprise front pipe 2, the Grouting Pipe 1 be built in front pipe 2, tee one-way valve 5, threeway explosive valve 6, L shape two-way valve 7 and return pipe 8, the external stability of front pipe 2 has pouch 4, described tee one-way valve 5, threeway explosive valve 6 are located in Grouting Pipe 1 successively, Grouting Pipe 1 is connected with pouch 4 by tee one-way valve 5, and threeway explosive valve 6 is for carrying out slip casting to interlude pvc pipe 12; Described return pipe 8 is connected with the L shape two-way valve 7 for overfall; Described Grouting Pipe 1, return pipe 8 are all flexible pipe.After described bag type paste, plug comprises rear pipe 10, Grouting Pipe 1 after fast joint continued access enters in pipe 10, and the outside of rear pipe 10 is also fixed with pouch 4, and the end entering the Grouting Pipe 1 in rear pipe 10 is provided with the L shape two-way valve one way valve 9 being communicated with pouch 4.The pouch of described front pipe 2 external stability and the pouch iron hoop 3 of rear pipe 10 external stability or fix with clip; Described front pipe 2 and rear pipe 10 all adopt pvc pipe, and they bond together with interlude pvc pipe 12 respectively.Described pouch 4 utilizes iron hoop 3 to be separately fixed on front pipe 2, rear pipe 10, and tee one-way valve 5, threeway explosive valve 6, L shape two-way valve 7, L shape two-way valve one way valve 9 all adopt screw-type, and be fixed on pipe with nut.
As shown in Figure 1, before bag type paste, the structure of plug is Grouting Pipe 1, return pipe 8 is built in front pipe 2, and Grouting Pipe 1 is connected with pouch 4 by tee one-way valve 5, for its slip casting; Threeway explosive valve 6 is for carrying out slip casting to interlude; Return pipe 8 connects L shape two-way valve 7, for overfall.Pouch 4 utilizes iron hoop 3 to be fixed on front pipe 2, and tee one-way valve 5, threeway explosive valve 6, L shape two-way valve 7 all adopt screw-type, and are fixed on front pipe 2 with nut.
After bag type paste, the structure of plug is that Grouting Pipe 1 is built in rear pipe 10 as shown in Figure 2, and Grouting Pipe 1 is connected with pouch 4 by L shape two-way valve one way valve 9, for its slip casting.Pouch 4 utilizes iron hoop 3 to be fixed on rear pipe 10, and L shape two-way valve one way valve 9 adopts screw-type, and is fixed on front pipe 2 with nut.
The course of work: first filled in boring by plug after bag type paste, is connected with fast joint 11 between slip casting pipeline section with slip casting pipeline section, and carries out the docking of pvc pipe 12, and finally plug after access bag type paste, connects grouting pump to its slip casting.In slip casting in earlier stage, pouch 4 slip casting simultaneously of front and back.When pouch 4 is filled with, the pressure now in Grouting Pipe 1 constantly increases, and when pressure reaches 2MPa, threeway explosive valve 6 explosion, carries out slip casting to the interlude of two plugs.Slurries enter splitting in (hole) gap of mash gas pumping drilling periphery under the effect of the pressure, realize the solidification sealing to boring.After interlude is filled with, slurries can flow out along return pipe 8, now can close grouting pump, complete whole hole-sealing grouting process.
