Abstract
A kind of means for loading having infiltration blast hole when excavating for tunnel blasting, at tunnel blasting, place is provided with blast hole, emulsion explosive cartridge is connected on bamboo chip, one end sealing of PE pipe, other end opening, bamboo chip is placed in PE pipe, is installed in blast hole by the PE pipe processed, and the adjacent sealing agent of Anchor Agent is placed on the remainder office of the blast hole beyond PE pipe.This device solve preferably blast hole have infiltration and blast hole install explosive can not powder charge problem at once in explosion situation.Especially, when running into unfavorable geology and water seepage hole, blast hole can not by the impact of external condition change, still can powder charge in high quality smoothly, and speed is fast, quality good, technique is simple, cost is low.Be particularly conducive to the blast hole of infiltration, adopt PE pipe and sealing agent to be enclosed in PE pipe by emulsion explosive cartridge, powder stick is isolated with infiltration, the reduction of demolition effect can not be caused by infiltration affects, powder charge is effective, fully can ensure charging quality, thus effectively ensures the quality of explosion.
Description
Technical field
When the utility model relates to a kind of tunnel blasting excavation, the charge constitution when blast hole has infiltration, particularly relate to a kind of when excavate for tunnel blasting, blast hole has infiltration and blast hole installs explosive, can not means for loading in horse back explosion situation.
Background technology
During tunnel blasting excavation, by the impact of engineering geology and hydrogeologic condition, in some cases, due to the existence of underground water, after blast hole drill completes, exist in the hole in and seep water, directly affect the powder charge of blast hole.When limiting by execution conditions, the blast hole installing explosive sometimes can not explosion at once, explosive needs to stay for some time in blast hole, sometimes explosive needs the time stopped in blast hole to reach 3 ~ 5 days, the way of current routine directly in blast hole, loads emulsion explosive cartridge, oozed water mitigation, easily occur before powder charge or collapse hole in powder charge process, fall slag, because of the rock ballast alluvial etc. that causes of seeping water cause this hole cannot complete powder charge or charging quality not high, and emulsion explosive cartridge is after infiltration is soaked, the reduction of demolition effect can be caused, even lost efficacy, the direct quality affecting Blasting Excavation.
Summary of the invention
For the problems referred to above, the utility model provides a kind of means for loading having infiltration blast hole when excavating for tunnel blasting, when solving tunnel blasting excavation preferably, blast hole has infiltration and blast hole installs explosive, can not powder charge problem at once in explosion situation.
The taked technical measures that solve the problem are:
A kind of means for loading having infiltration blast hole when excavating for tunnel blasting, it is characterized in that: be provided with blast hole 1 at tunnel blasting place, PE pipe 2 is set to sealed end near the one end at blast hole 1 end, orifice end is set near one end of blast hole 1 mouthful, emulsion explosive cartridge 4 is connected on bamboo chip 3, bamboo chip 3 is placed in PE pipe 2, sealing agent 5 is placed on the orifice end of PE pipe 2, be installed in blast hole 1 by the PE pipe 2 processed, the adjacent sealing agent 5 of Anchor Agent 6 is placed on the remainder office of the blast hole 1 beyond PE pipe 2.
the beneficial effects of the utility model: when this means for loading solves tunnel blasting excavation preferably, blast hole has infiltration and blast hole installs explosive, can not powder charge problem at once in explosion situation.Especially, when running into unfavorable geology and water seepage hole, blast hole can not by the impact of external condition change, still can powder charge in high quality smoothly, and powder charge speed is fast, quality good, technique is simple, cost is low.Be particularly conducive to the blast hole of infiltration, even if explosive needs the time stopped in blast hole to reach 3 ~ 5 days, because it adopts PE pipe and sealing agent to be enclosed in PE pipe by emulsion explosive cartridge, emulsion explosive cartridge is isolated with infiltration, also the reduction of demolition effect can not be caused by infiltration affects, powder charge is effective, fully can ensure charging quality, thus effectively ensures the quality of explosion.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described.
A kind of means for loading having infiltration blast hole when excavating for tunnel blasting, as shown in Figures 1 to 4, blast hole 1 is provided with at tunnel blasting place, PE pipe 2 is set to sealed end near the one end at blast hole 1 end, orifice end is set near one end of blast hole 1 mouthful, emulsion explosive cartridge 4 is connected on bamboo chip 3, bamboo chip 3 is placed in PE pipe 2, sealing agent 5 is placed on the orifice end of PE pipe 2, be installed in blast hole 1 by the PE pipe 2 processed, the adjacent sealing agent 5 of Anchor Agent 6 is placed on the remainder office of the blast hole 1 beyond PE pipe 2.
Concrete operation method of the present utility model is: after tunnel blasting place adopts drill hole of drilling machine to form blast hole 1, and employing high-pressure blast, water under high pressure carry out hole clearly, the residue in blast hole 1, mud etc. are cleaned out, PE pipe 2 is processed by designing requirement, the external diameter 15mm less of the diameter of blast hole 1 of PE pipe 2, length 0.5 ~ 1.0m shorter in the degree of depth of blast hole 1, wall thickness is 1.5 ~ 2mm, seal near the one end at blast hole 1 end, near the one end open of blast hole 1 mouthful, emulsion explosive cartridge 4 adhesive tape is tied up after on bamboo chip 3, put into PE pipe 2, remain in about 50cm length range in the orifice end of PE pipe 2 and fill up sealing agent 5, then by the PE pipe 2 that processes together with bamboo chip 3, emulsion explosive cartridge 4 is installed in blast hole 1 together with sealing agent 5, then the adjacent sealing agent of Anchor Agent 65 is by closely knit for the blocking of the remainder of the blast hole 1 beyond PE pipe 2.So just complete powder charge in high quality smoothly, speed is fast, quality good, technique is simple, cost is low.For the blast hole having infiltration, even if explosive needs the time stopped in blast hole to reach 3 ~ 5 days, because adopting PE pipe and sealing agent, emulsion explosive cartridge is enclosed in PE pipe, emulsion explosive cartridge is isolated with infiltration, also the reduction of demolition effect can not be caused by infiltration affects, powder charge is effective, fully can ensure charging quality, thus effectively ensures the quality of explosion.
