Description
Technical field
The present invention relates to injecting paste material technical field more particularly to a kind of airport runway surface reparation injecting paste materials.
Background technology
At present, airport road surface is mostly concrete or asphalt material, and also there is leakages in use on surface
The disease incidences such as water and cracking, existing LB mending technique mostly repair road injury region using the method for direct cement injection
It mends, the selection of wherein injecting paste material is the basic problem of slip casting recovery project, is to ensure that slurry injection technique accomplishes the end in view most
Key factor is to reduce project cost, cost-effective key point.
Modern injecting paste material is broadly divided into bulk material, chemical material and is answered by what bulk material and chemical material formed
Condensation material.Granular slurry material based on cement have that set strength is high, material source is wide, price is low, transport storage is convenient and
The advantages that grouting process is simple is the main body of injecting paste material.But since common cement granules are thicker, it can only generally be filled into diameter
In hole more than 0.2mm, centering, fine pore are not easy to be perfused, and since its setting time is long, are there is the water of certain flow rate
Slurries are easily diluted with water or wash away application ranges before solidification and limited to when flowing position injecting treatment.Chemical grouting is
One new technology of project seepage controlling is widely used to the fields such as tunnel maintenance reinforcing in external chemical grouting water blockoff antiseepage, with
Traditional cements slurry injection technique is compared, and chemical grouting has its unique advantage, can be solved traditional cements grouting method and is difficult to solve
Engineering roadblock.Chemical grouting material has preferable concrete castability than cement grouting material, and slurry viscosity is low, can be injected into fine pore,
And the setting time of its slurries can be adjusted by engine request, can reach gelled instantaneously sometimes, compares and is suitble to having circulating water
Position carries out leak stopping or Anti-seeping technology.
Although being continued to develop by leading chemical grouting technology of various new materials, economic factor and environmental protection are limited to
Etc. reasons, cement injection material is still in occupation of the leading position of injecting paste material.For the deficiency of cement grouting material and chemical grouting material,
The work of the existing injecting paste material of a large amount of improvement and development of new injecting paste material has been carried out in countries in the world, be proposed a collection of high intensity,
High osmosis, high performance modified slurry material, wherein most of acquired achievement is cement mortar modification, i.e. cement-based grout material
Material, the kind for being seen in report have reached over one hundred kind or more.
Generally speaking, the current reparation that captain road surface is used for using injecting paste material, the rapid hardening effect that more covets and strong
Degree, pumpability and dispersion resistance for material consider deficiency.After material injects water-bearing structure, easily diluted by broken off by water flush, from
And set injecting paste material Mortar mix proportion is changed, original performance is lost, water-bearing structure can not effectively be blocked.Together
When, injecting paste material price is also costly the bottleneck for restricting its extensive engineer application at present.
The content of the invention
The present invention proposes a kind of airport runway surface reparation injecting paste material, this kind of injecting paste material can resist current punching
Brush, is not water dispersible, while has dispersion resistance in good slip casting pumpability and water.

The preparation method of the airport runway surface reparation injecting paste material includes, by portland cement, polymer latex
Breast, flyash, gangue, aggregate are placed in mixer, are stirred evenly under the conditions of rotating speed is 300-800r/min, water is added to continue
1-3min is stirred, light material, sodium salt accelerator, thickener, water-reducing agent and activating agent stirring 3-5min is added, obtains mix
The mixture is placed in curing box and conserves by object, obtains the airport runway surface reparation injecting paste material.
Airport runway surface reparation of the present invention plays skeleton work by the use of injecting paste material using alumina silicate cement as base material
With；It is added to by the way that flyash and coal are ground stone in the alumina silicate cement, the two compounding can play the grading effect of micro-aggregate
Should, aquation generates substantial amounts of gelinite, so as to adjust the internal structure state and hole characteristic of cement, improves density, promotes mixed
The raising of solidifying soil intensity, so that finally formed injecting paste material is not easy to disperse under high-velocity flow effect, coagulating property enhancing；Water
Property epoxy resin and SBR styrene-butadiene latexes composition polymer emulsion can be wrapped in the surface of all mineral raw materials and be filled in ore deposit
In the gap of matter raw material, the mechanical properties such as the toughness of cement are not only improved, more importantly compensate for current rapid hardening slip casting material
Material is not easy to manipulate, does not resist the shortcomings that scattered in water, substantially increases its coagulating property；In addition the aggregate added in is quartz sand, is led to
It crosses to the varigrained configuration of quartz sand, cement porosity and isolation lamination can be reduced, so as to adapt to various notes
Starch the requirement to injecting paste material in engineering；The additional modifying agent that sodium salt accelerator, thickener, water-reducing agent and activating agent form, energy
Gap distribution inside adjustment, suffered resistance when reducing injecting paste material perfusion, and the formation of cement-hydrate is influenced, subtracted with reaching
Impervious purpose is shunk, prevents from cracking and improved less.
Compared with prior art, airport runway surface reparation injecting paste material of the present invention compensates for current slip casting material
The shortcomings that material is not easy to manipulate, is not anti-scattered in water, relatively common injecting paste material grouting operation easily cause grouting pipeline block or
The problem of drilling blocks, injecting paste material of the present invention is able to maintain that paste time 5-20min.Ordinary cement-waterglass slip casting
Material 1h intensity is generally less than 2Mpa, and injecting paste material highest of the present invention can reach 3.5Mpa, therefore of the present invention
Injecting paste material can be matched according to engineering demand by changing, and adjust initial set and the final setting time of injecting paste material, effective
In the harnessing project of aviation runway.
