Slurry equipment is injected in stratum (Rock And Soil) by Grouting Pipe, serosity with infiltration, filling, cleave, squeeze
The mode such as close spreads in Rock And Soil, along with condensation, the hardening of serosity, forms knot in the space on stratum
" Seed harvest " or " gel " that structure is more complete, waterproof impervious characteristic is high and chemical stability is good, with
Time also can by cementing to originally the loosest grogs or crack etc. be an entirety, reaching to reinforce by note stratum or
The purpose of impervious leakage-stopping.For the construction of slip casting, anchor bar/anchor cable, cast-in-situ bored pile etc. and natural
For the exploration of gas hydrate, oil shale, shale gas, oil/gas, subsoil water etc. or exploitation,
The first step of the technological process being usually taken is all to be drilled to the boring of certain specification on request, thus is follow-up
In Rock And Soil, inject serosity, insert anchor bar/anchor cable, transfer steel reinforcement cage and pour pile, or under enter phase
Suitable exploration or Mining Equipment etc. are prepared.
During drilling and forming hole, conventionally employed drilling tool and boring method mostly are one drill bit of employing and enter
The bore operation of row, this can only be drilled to an aperture single borehole consistent with drill bit specification.There may come a time when
Can because of some unpredictable factors (Borehole Diameter that such as hole wall instability causes, cave in), or
It is to change drilling design requirement due to Party A temporarily, in order to meet the drilling design requirement that Party A proposes, needs
The path boring being previously drilled to is carried out reaming to increase its aperture, in order to transfer more wide-aperture note
Slurry pipe tool or miscellaneous equipment etc., now according to conventional way, just can only change a bigbore drill bit
The downward cleaning bottom of hole or use reamer to carry out reaming so that boring reaches required aperture the most again from earth's surface；Before
Person, the method for downward cleaning bottom of hole the most again can not give full play to green bit from earth's surface to change a bigbore drill bit
Usefulness because the green bit now changed is only drill bit circumference outer ring and Rock And Soil during cleaning bottom of hole
The cutting kata-rocks soil body when part of contact is crept into, and the drill bit circumference inner ring not contacted with Rock And Soil
Part does not the most play a role, until using this green bit to complete drill bit circle after cleaning bottom of hole work
When all outer perimeter section are scrapped, the circumference inner round portion of this drill bit did not the most use, and this can make undoubtedly
Become the waste of green bit；The latter, when using reamer that the path boring being previously drilled to is carried out reaming,
Although the aperture being previously drilled to path boring can be increased, but reamer can complete the degree of depth one of reaming
As maximum be only the hole depth being previously drilled to path boring, after completing ream operation, if thinking to add further
The deep path boring being previously drilled to, then need to carry after reamer is replaced with the drill bit that size is suitable by brill again
Being transferred by drilling tool and be then drilled down into at the bottom of hole, this process wastes time and energy beyond doubt, not only increases
Carry the non-cutting time bored with more bit change, also reduce the working performance boring reaming construction simultaneously.
