Abstract
本发明公开了一种用于道路修复加固的有机‑无机复合型注浆料，由有机料和无机料复合形成，有机料为高粘改性乳化沥青，无机料是由水泥、粉煤灰、石膏、膨胀剂、减水剂、早强剂和纤维构成；由下述重量份的原料制成：高粘改性乳化沥青40～50份，水泥15～45份，粉煤灰5～10份，石膏粉10～20份，膨胀剂0.01～0.03份，早强剂1～5份，减水剂1～3份，纤维0～0.003份，水2～10份；所述的高粘改性乳化沥青由如下重量百分比的组分组成：基质沥青60～65％，SBS 2～3％，增粘剂3～5％，交联剂0.02～0.03％，相容剂3～6％，阳离子乳化剂1.5～3.0％，酸度调节剂2.5～4.5％，余量为水。The invention discloses an organic-inorganic composite grouting material for road repair and reinforcement. It is composed of gypsum, expansion agent, water reducing agent, early strength agent and fiber; it is made of the following raw materials in parts by weight: 40-50 parts of high-viscosity modified emulsified asphalt, 15-45 parts of cement, and 5-10 parts of fly ash , 10 to 20 parts of gypsum powder, 0.01 to 0.03 parts of expansion agent, 1 to 5 parts of early strength agent, 1 to 3 parts of water reducing agent, 0 to 0.003 parts of fiber, and 2 to 10 parts of water; the high viscosity modified The emulsified asphalt is composed of the following components by weight: base asphalt 60-65%, SBS 2-3%, tackifier 3-5%, cross-linking agent 0.02-0.03%, compatibilizer 3-6%, cationic emulsifier 1.5-3.0% of the acidity regulator, 2.5-4.5% of the acidity regulator, and the balance is water.
Description
Technical field
The present invention relates to a kind of organic-inorganic compoiste grout materials reinforced for road rehabilitation, are specifically used for road work
Journey subgrade and pavement repairs that grouting and reinforcing, concrete floor come to nothing and hazard to bridge's pier comes to nothing the fields such as grouting and reinforcing.
Background technique
Here statement only provides background information related to the present invention, without necessarily constituting the prior art.
Due to the influence of traffic loading and environment, appearance early disease that road can be different degrees of during military service.Road
The common disease of base mainly includes depression, comes to nothing, bursts and become muddy when a thaw sets in, and the common disease in road surface has crack, pit slot, depression frost boiling etc..This
A little diseases not only largely reduce the service performance of road, also substantially reduce the service life of road, give highway administration
Department highway maintenance in terms of cause huge technological challenge and economic loss.The method of these diseases is punished at present
There are the cementation of fissures, cover, milling to spread again.However engineering practice shows that these methods are only to solve cosmetic issue, the disease of roadbed
Evil is showed often through forms such as crack, the sedimentations on road surface, when disease is due to subgrade strength deficiency, roadbed settlement and to take off
When the reasons such as sky cause, above-mentioned punishment mode is often palliative, and disease can repeated, and results in waste of resources and economy is damaged
It loses.The punishment of existing roadbed is generally required to excavate former road surface and needs to drive piles, drill etc., maintenance time is long, influences traffic
It is current.
Slurry injection technique starts more and more to be applied to the fields such as roadbed filling, foundation stabilization and underground engineering reinforcing.
Slurry injection technique is that slurries indentation such as is come to nothing at the diseases by applying certain pressure in the position drilling implantation Grouting Pipe to need reinforcement
Evil position, improves the physical and mechanical property of unfavorable geology.Wherein injecting paste material is the key factor of grouting reinforcement technique, performance
