Description
Technical field
The present invention relates to mix two fluid grouting pipe at the bottom of a kind of fixed point control hole, territory.
Background technology
Grouting engineering two fluid grouting adopts sleeve pipe sealing of hole more, and protrusive naked hole slip casting can not realize the strengthening slip casting of fixed point region, and in slip casting process, multiple brill amount is large, required long in time limit, deficiency in economic performance, and slip casting effect is difficult to guarantee.In the time of country rock soft broken, exist because multiple brill amount causes greatly collapse hole to embrace brill accident occurrence frequency and enlarge markedly, borehole collapse causes the unmanageable difficult problem of slurries range of scatter.Grouting engineering weakness zone adopts while directly play the strengthening slip casting of steel pipe fixed point control territory, and the steel pipe that defect is to hole and steel pipe can not be recycled, deficiency in economic performance and existence reside in country rock region affects follow-up periphery drilling construction.
Summary of the invention
Object of the present invention is exactly in order to address the above problem, at the bottom of being provided, a kind of fixed point control hole, territory mixes two fluid grouting pipe, it has simple in structure, applicable field fabrication, steel pipe and boring recoverable, does not affect follow-up drilling construction, can significantly reduce multiple brill amount, shorten the construction period, save slip casting expense, improve the advantages such as slip casting effect.
For achieving the above object, the present invention is by the following technical solutions:
A kind of fixed point control mixes two fluid grouting pipe at the bottom of hole, territory, comprise: auxiliary tube, Grouting Pipe outer tube, Grouting Pipe inner tube and be located in Grouting Pipe outer tube, Grouting Pipe inner tube penetrating slurry hole, described auxiliary tube internal diameter is greater than Grouting Pipe outer tube external diameter, described Grouting Pipe outer tube except conical end all in auxiliary tube, described Grouting Pipe outer tube diameter is greater than Grouting Pipe inner tube external diameter, described Grouting Pipe inner tube end is provided with check ball valve, the gradient of described auxiliary tube end and horizontal plane is 15 °～30 °, and described Grouting Pipe outer tube and inner tube afterbody are provided with connection end.
Described auxiliary tube is non-metallic pipe.
Preferably, described auxiliary tube is pvc pipe.
Filling fluid sealant in the gap of described auxiliary tube end and Grouting Pipe outer tube, auxiliary tube is except end and gap inner filling butter or the vaseline sliding agent of Grouting Pipe outer tube.
Described connection end is welded on Grouting Pipe outer tube, and with Grouting Pipe inner tube by screwed connection.
Described connection end is provided with the Grouting Pipe A of UNICOM's Grouting Pipe outer tube and the Grouting Pipe B of UNICOM's Grouting Pipe inner tube.
Beneficial effect of the present invention:
1 the present invention can directly reinforce emphasis weakness zone, reduces multiple brill amount, greatly reduces the occurrence frequency of embracing brill accident, shortens the construction period, saves slip casting expense, improves slip casting effect;
2 the present invention are simple in structure, are applicable to field fabrication, steel pipe recoverable, and pvc pipe is cheap, significantly reduce the cost of fixed point control territory novel slurry filling pipe;
3 the present invention stay the auxiliary tube in boring, and intensity is low, and boring can reuse, and do not affect the construction of follow-up boring;
At the bottom of 4 the present invention adopt hole, biliquid mixes, and for rapid hardening plasmoid humor better adaptability, the moving water of the larger flow velocity of easier shutoff, is especially applicable to curtain deep hole fixed point control territory two fluid grouting and water currents and moves significantly two fluid grouting under water condition.
Accompanying drawing explanation
Fig. 1 is profile of the present invention.
Wherein, 1. auxiliary tube, 2. Grouting Pipe outer tube, 3. Grouting Pipe inner tube, 4. Grouting Pipe A, 5. Grouting Pipe B, 6. connection end, 7. penetrates slurry hole, 8. check ball valve, 9. fluid sealant, 10. sliding agent.
The specific embodiment
A kind of fixed point control mixes two fluid grouting pipe at the bottom of hole, territory, as shown in Figure 1, comprise: auxiliary tube 1, Grouting Pipe outer tube 2, Grouting Pipe inner tube 3 and be located at Grouting Pipe outer tube 2, penetrating in Grouting Pipe inner tube 1 starched hole 7, described auxiliary tube 1 internal diameter is greater than Grouting Pipe outer tube 2 external diameters, described Grouting Pipe outer tube 2 except conical end all in auxiliary tube 1, described Grouting Pipe outer tube 3 internal diameters are greater than Grouting Pipe inner tube 3 external diameters, described Grouting Pipe inner tube 3 ends are provided with check ball valve 8, prevent slurry reflux, the gradient of described auxiliary tube 1 end and horizontal plane is 15 °～30 °, described Grouting Pipe outer tube 2 is provided with connection end 6 with inner tube 3 afterbodys.
Described auxiliary tube 1 is non-metallic pipe.
Preferably, described auxiliary tube 1 is pvc pipe.
Filling fluid sealant 9 in the gap of described auxiliary tube 1 end and Grouting Pipe outer tube 2, prevent underground water and slurries enter auxiliary tube and Grouting Pipe intermittently in, destroy the lubricant effect of sliding agent, cause slip casting to finish grouting behind shaft or drift lining pipe and be difficult to extract from auxiliary tube; Auxiliary tube 1 except end and gap inner filling butter or the vaseline sliding agent 10 of Grouting Pipe outer tube 2, is convenient to slip casting and is finished grouting behind shaft or drift lining pipe and can in auxiliary tube, extract.
