Description
Technical field
The invention belongs to bridge construction field of material technology, and in particular to a kind of bridge back-tension prestressed channel mudjacking material and
Its preparation method.
Background technology
Peak in current bridge prestress pore channel mud jacking work progress in curvilinear conduit has a number of float
Slurry, light materials of the laitance in grouting material raw material, low intensity and loose.These light materials during mud jacking
Floating can be formed in the presence of pressure and in the voltage stabilizing phase, and the bleeding produced under pressure in hardening process can also drive
Light materials float.These light materials are included：Light materials in gypsum, flyash, volcanic ash and grouting agent；And regarding duct length,
The curve discrepancy in elevation, the kind of grouting material and have difference, the laitance thickness of generation is generally 0.3mm ~ 30mm.According to related request, pressure
The closely knit situation of mud jacking should be spot-check after slurry by inspection hole, if any unreal, benefit Dispose by grouting should be carried out in time.And in line construction
During find, at the uncompacted position of mud jacking, although carried out benefit Dispose by grouting, but be due to the presence of this layer of laitance,
Badly influence the effect of ftercompction slurry, and this layer of laitance low intensity and loose, cause point after secondary ftercompction slurries hardening
Layer phenomenon, jeopardizes the corrosion of prestressing force steel hinge line, or even cause steel hinge line to be broken, and has influence on the security, resistance to of bridge structure
Long property.
The content of the invention
For problems of the prior art, present invention aims at provide a kind of bridge back-tension prestressed channel mudjacking
Material and preparation method thereof.
Described a kind of bridge back-tension prestressed channel mudjacking material, it is characterised in that the grouting material is ripe by portland cement
Material, miberal powder, grouting agent composition, described Portland clinker, miberal powder, the proportioning of grouting agent are：Portland clinker 55%
~ 85%, the grouting agent 5% ~ 25% of miberal powder 5% ~ 25%.
Described bridge back-tension prestressed channel mudjacking material, it is characterised in that described Portland clinker, miberal powder, pressure
Slurry agent, which is matched, is preferably：Portland clinker 60% ~ 80%, miberal powder 10% ~ 20%, grouting agent 10% ~ 20%.
Described bridge back-tension prestressed channel mudjacking material, it is characterised in that described Portland clinker, miberal powder, pressure
Slurry agent, which is more preferably matched, is：Portland clinker 65% ~ 75%, miberal powder 12% ~ 18%, grouting agent 12% ~ 18%.
Described bridge back-tension prestressed channel mudjacking material, it is characterised in that described Portland clinker, miberal powder, pressure
Starching the best proportioning of agent is：Portland clinker 70%, miberal powder 15%, grouting agent 15%.
The preparation method of described bridge back-tension prestressed channel mudjacking material, it is characterised in that described portland cement is ripe
Material is uniformly mixed and stirred obtained by grinding with described miberal powder, grouting agent.
Above-mentioned bridge back-tension prestressed channel mudjacking material, technique is simple, and key is free of gypsum, flyash, volcanic ash and pressure
The light materials in agent are starched, under the effect of the pressure and in voltage stabilizing phase, hardening period during bridge prestress pore channel mud jacking, not
Laitance can be produced in the peak of curvilinear conduit, intensity is high, point after two layers of slurries hardening is not resulted in when mending Dispose by grouting yet
Layer phenomenon, effectively prevents corrosion, the fracture of prestressing force steel hinge line, and security, durability to bridge structure have significant impact,
Possesses the meaning being widely popularized.
Embodiment
The present invention is described in further detail below by way of specific embodiment.
Embodiment 1：

Portland clinker be using lime stone and clay as primary raw material, through broken, dispensing, it is levigate raw material are made, so
Calcined afterwards in cement kiln.Miberal powder generally refers to the material obtained by mined ore is carried out after pulverizing processing
Powder.Grouting agent have microdilatancy, ungauged regions, big flowing, self-compaction, extremely low bleeding rate, fullness degree is high, intensity is high, antirust resistance is become rusty,
Low alkali out of chloride, bond degree are high, the premium properties of environmental protection, oxide-free, chloride, sulphite and nitrite etc. pair
Reinforcing bar is harmful to component, is become rusty by high-performance plastic agent, surfactant, silico-calcium micro-expanding agent, hydration inhibitors, migration-type resistance
The refined grouting agent or refined multiple with low alkali low-heat portland cement etc. of agent, nanoscale mineral sial calcium iron powder, stabilizer
The grouting material closed.Portland clinker, miberal powder, grouting agent in above-described embodiment are all being directly to buy on the market
Arrive.
