It causes soft rock to be disintegrated, and soft rock intensity can be improved, simple and effective ensures the safety of construction period；The thickness of modified epoxy protective layer 1
Degree is 0.1mm ~ 0.3mm, and modified epoxy and side slope surface concrete adhesive strength are greater than 2MPa.
The laying spacing of capillary drainpipe 23 is 250cm ~ 350cm, is " Technique Code for Building Slope Engineering " recommended value,
Side slope internal water can be effectively excluded, the gradient of capillary drainpipe 23 is 1%-4%, and capillary drainpipe 23 is laid in slope by quincunx
The infiltration in side slope is discharged for face, capillary drainpipe 23, flows into gutter 22 along slope surface.
Modified epoxy is sprayed at side slope surface by several times and forms modified epoxy protective layer 1, with strong-hydrophobicity, and with
The concrete bonding intensity on side slope surface is greater than 2MPa, and modified epoxy protective layer 1 is after drying with a thickness of 0.1mm ~ 0.3mm, reference
" epoxy resin waterproof coating " professional standard, to ensure the entire slope surface of material coating with protection benefit and not causing material unrestrained
Take.Comprising the various active functional group including hydroxyl etc. in modified epoxy, dehydrating polycondensation can occur with rock sample surface hydroxyl
Reaction generates and is bonded firm Si-O-Si key, therefore modified epoxy protective layer 1 and rock sample have excellent connecting performance；Change
Property epoxy resin and the interaction of rock sample surface hydroxyl form the organic silicon hydrophobic film layer of cross-linked structure and be covered in rock sample
Surface makes rock sample surface become hydrophobicity from hydrophily；It is sprayed herein using mechanical delamination, improves operating efficiency, and uniformity
More preferably.
Drainage system is arranged in step S3: excavating intercepting ditch 21 in top of the slope, excavates gutter 22 in bottom of slope, drain in capillary
The mark of pipe 23 digs infiltration groove, places capillary drainpipe 23, the inner end built-in edges of capillary drainpipe 23 in infiltration groove
Inside slope, the outer end of the protruding slope surface in 23 outer end of capillary drainpipe, capillary drainpipe 23 is tilted to bottom of slope, passes through capillary structure
The infiltration water in rock stratum is absorbed and is discharged with siphon principle, cooperation bottom of slope gutter 22 forms complete drainage system.
Step S4, wet drilled as holes: in the mark of anchor hole, using wet brill method drilling anchor solid hole, during drilling anchor solid hole
Organic-silicon-modified resin is injected as coolant liquid, and cooling drill bit carries boring mud, while crack 31 of the coolant liquid around hole wall is seeped
Enter, coolant liquid solidifies post-reinforcing anchor hole surrounding rock body, inhibits rock mass disintegration in water；
Coolant liquid is poured into hole in drilling, cooling effect is played during circulation, and boring mud band is portalled outside, bored
Drill bit can disturb soft rock and generate many cracks 31 during hole, and crack 31 of the coolant liquid when pouring into around hole wall is infiltrated, and
Solidify over time, plays reinforcement effect；
The preparation of organic-silicon-modified resin: to mix oxysilane monomer as raw material, under without using solvent xylene medium directly
Row hydrolytic condensation is tapped into, the reactive silicone oligomer with good compatibility is made, then by silicone oligomer and epoxy
Resin polycondensation obtains modifying epoxy resin by organosilicon；In view of that need to have preferable mobility as coolant liquid, the present invention is preferred
Ethoxysilane is raw material, and during hydrolytic condensation, coproduct ethanol is the good solvent of Ethoxysilane, water, silanol, is made
Silanol concentration reduces, to slow down its polycondensation speed, avoids resin premature gelation, and it is convenient to provide for construction；Organosilicon
Modified resin solidifies under room temperature (18-22 DEG C), containing functional groups such as hydroxyl, methyl, carboxyl and epoxy groups, occurs with soft rock
Reaction plays the role of reinforcing, prevents blending inhibition disintegration, effectively the hole wall surrounding rock body of side slope surface layer and anchor hole inhibited to be constructed
Strength deterioration problem after disturbance and chance water.
Step S5, install anchor pole 32: the depth to anchor hole reaches design requirement, using high pressure air duct borehole cleaning, until in hole
Without rock powder, rock ballast, anchor pole 32 is put into anchor hole, the casting cement mortar between anchor pole 32 and anchor hole, forms grouting layer
33, cement mortar with mix with, guarantee slurries initial set before be finished.
Step S6 pours protective layer 4: after the installation detection of anchor pole 32, being laid with steel mesh on modified epoxy protective layer 1
41, steel mesh 41 is welded and fixed with 32 junction of anchor pole, and after laying, casting concrete layer 42 forms anti-on steel mesh 41
Sheath 4, protective layer 4 with a thickness of 3cm ~ 5cm.
Soft Rock Slope drilling anchor solid hole generallys use wet brill method, and boring procedure is poured into hole with clear water, play cooling drill bit and
Boring mud effect is carried, but boring procedure can cause disturbance to form crack 31 to anchor hole surrounding rock body, and water can be seeped along crack 31
Enter, lead to soft rock disintegration in water, destroys slope stability.The present invention replaces clear water using organic-silicon-modified resin, can play
Cooling, carrying boring mud effect, organic-silicon-modified resin penetrate into soft rock along crack 31, solidify in crack 31, reduce drilling and disturb
Influence to rock mass, can waterproof and consolidating crack, improve anchoring effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the scope of the present invention.It is all
Any modification, equivalent replacement, improvement and so within the spirit and principles in the present invention, are all contained in protection scope of the present invention
It is interior.
