Abstract

The inert grout for shield tunnel after-wall grouting process is composed of (kg/cu.m) quicklime 40-100, flyash 200-600, bentonite 40-100, fine sand 800-1200, water 200-400 and additive 0-40, the additive is soda or carboxymethylcellulose sodium, i.e. CMC. Said invented grout is an inert grout which is made of quicklime and flyash as main raw material, and its fluidity, thickness, stratification and setting time can meet the requirement for shield construction, and the grout property can be effectively controlled by regulating addition quantity of the additive.

Description

Shield tunnel grouting behind shaft or drift lining inert slurry
Technical field
The present invention relates to a kind of constructing tunnel grouting serous fluid.
Background technology
At present, in subterranean tunnel engineering shielded construction, shield tail synchronous grouting, used injecting paste material mainly is divided into single-liquid type and two-pack type two big classes.Single liquid with dual-liquid slip-casting material because composition material different respectively have characteristics on performance.The many employings of shield structure grouting behind shaft or drift lining contain single liquid slurry of cement or the biliquid slurry that cement adds water glass in the world.The two-pack type slurry material is divided into A liquid and B liquid, and A liquid cement, sand and water, B liquid are water glass.Existing single-liquid type injecting paste material is a host with cement, flyash, and composition has: cement, flyash, fine sand, wilkinite (also claiming sodium soil) and water.The easy plugging of existing single-liquid type cement grout, pipeline cleans very difficult, and it is very long to clean required time.Compare with the two-pack type injecting paste material, though there is shortcoming in the single-liquid type injecting paste material in the aspects such as control in intensity, flowability, presetting period in early days, also have easy construction, manage advantages such as easy.
Technology contents
The present invention will solve low, mobile relatively poor, the uppity problem of presetting period of single-liquid type grouting serous fluid early strength, make the grouting behind shaft or drift lining construction more convenient, help reducing cost, improve work efficiency, improve construction quality, effectively control ground settlement.
The technical scheme of shield tunnel grouting behind shaft or drift lining inert slurry of the present invention: it is characterized in that: the weight proportion of its slurries (kg/m3):
Unslaked lime: 40-100,
Flyash: 200-600,
Wilkinite: 40-100,
Fine sand: 800-1200,
Water: 200-400,
Additive: 0-40.
Above-mentioned additive can be soda ash if wilkinite is calcium soil.
Above-mentioned additive also can be sodium carboxymethyl Mierocrystalline cellulose, i.e. CMC.
Above-mentioned additive can also be sodium carboxymethyl Mierocrystalline cellulose and soda ash.
Beneficial effect: single fluid grouting inert slurry of the present invention is a host with unslaked lime, flyash, and composition has: unslaked lime, flyash, fine sand, wilkinite (also claiming sodium soil) and water.With flyash as slurry consolidation intensity being provided and regulating the slurries material of time of coagulation, improve workability, the flowability of slurries simultaneously, unslaked lime can increase the viscosity of slurries, and certain consolidation arranged, wilkinite is in order to slow down the material separation of slurries, reduce bleeding rate, also have certain antiseepage effect, sand in two kinds of slurries all as stopping composition.
The present invention has good long term stability and mobile, and can guarantee the suitable presetting period, to adapt to shielded construction and remote requirement of carrying.Has good filling performance.Satisfying under the prerequisite of mortar depositing construction, obtaining to be higher than the early strength on stratum as early as possible.Slurries are difficult for producing dilution phenomenon in groundwater environment.Volumetric shrinkage is little after the slurry consolidation, and bleeding rate is little.Raw material sources are abundant, economical, and construction management is convenient, and slurries are nuisanceless, low price.And can satisfy the requirement of construction automatic technology.
Grouting serous fluid of the present invention is to be the inert slurry of host with unslaked lime and flyash, its flowability, denseness, delamination degree and time of coagulation all can be satisfied the shield driving needs, and can effectively control the performance of slurries by the incorporation of regulating additive, to adapt to the requirement of Different Strata, different driving progress to size performance.It is simple to have batching, and low cost of manufacture is produced easily, and workability can be good, and construction management is convenient, the section of jurisdiction does not have faulting of slab ends substantially, anti-stop ring longitudinal joint seepage, and Land-Subsidence Control is within allowed band.
Adopt the inert slurry synchronous grouting, slurry fluidity is better.Compare with cement grout, time of coagulation is longer, about 10-12 hour.Reasonably work team of presetting period and shield driving construction can arrange the cleaning of transfer line around so again when per tour finishes.Neither influence the shield structure and construct continuously, guarantee in time to clear up pipeline again, avoided the plugging phenomenon, shorten scavenging period, accelerated speed of application, the duration also can shift to an earlier date, be applicable to the shield tunnel construction, grouting behind shaft or drift lining combines with piecing assembly precast concrete section of jurisdiction synchronously, and waterproof effect improves greatly than Mine Method, avoided tunnel dewatering project along the line simultaneously, construction speed is fast, and construction process safety is especially long at tunnel distance, under the tight situation of construction period, benefit is more remarkable.
Embodiment
The embodiment of the proportioning of inert slurry (weight ratio kg/m3): unslaked lime: flyash: wilkinite: fine sand: water: additive=(40-100): (200-600): (40-100): (800-1200): (200-400): (0-40) test used inert slurry proportioning (each material usage unit is kg/m3):
Fine sand calcium lime powder coal ash bentonite water additive proportioning embodiment one 1,100 50 250 80 300 40 proportioning embodiment 2 1,000 100 200 90 350 25 proportioning embodiment 3 800 40 550 100 400 35 proportioning embodiment 4 1,200 90 600 70 350 20 test implementation examples 5 1,100 50 350 40 250 12 proportioning embodiment 6 1,080 60 300 100 300 proportioning embodiment 7 900 80 400 50 360 proportioning embodiment 8 1,000 80 400 60 340 proportioning embodiment 9 1,000 80 400 50 340 16 test implementation examples 10
Above proportioning can all can satisfy the requirement of shield tunnel grouting behind shaft or drift lining according to the preparation of engineering particular case. and the composition material of its inert slurry is unslaked lime, flyash, fine sand, wilkinite and additive, and additive is soda ash and CMC, i.e. the sodium carboxymethyl Mierocrystalline cellulose.Wherein flyash provides slurries required consolidation strength; Unslaked lime can increase the viscosity of slurries; Wilkinite reduces bleeding rate in order to slow down the material separation of slurries, also has certain antiseepage effect; Sand in slurries as stopping composition; The effect of CMC is the viscosity that improves slurries, increases yield value, prevents precipitation; If wilkinite is a then admixture soda ash of calcium soil, make Ca ion generation inertia and do not make the Na ion produce inertia, if wilkinite is a sodium soil, then do not need admixture soda ash.
