Description

Cut-off wall slurry material and wall building technique
Technical field
The invention belongs to underground seepage control project field, be specifically related to a kind of cut-off wall slurry material and wall building technique.
Background technology
60~eighties of 20th century, China's cut-off wall material mainly adopts rigid materials such as normal concrete (or Steel Concrete), clay concrete and flyash concrete, these concrete material ultimate compression strength height (5~35MPa), Young's modulus big (15000~32000MPa), be suitable for doing coefficient underground wall bodies such as antiseepage, retaining soil and load-bearing.If only be used for the antiseepage effect, too high (600~1200 yuan/m of employing rigid materials as its construction costs of body of wall 2), and local cracking phenomena easily takes place in rigid concrete under the foundation soil horizontal force action, cause impervious ability to reduce on the contrary.
To the eighties in 20th century, China's cut-off wall material has had great innovation.Flexible materials for walls such as plastic concrete, self-solidifying mortar constantly come out.The materials for wall of this class flexibility is because of containing clay, flyash, water glass and other admixture, present very big plasticity after the slurry material is fixed, its ultimate compression strength lower (0.1~5MPa), Young's modulus is less than 2000MPa, be that foundation soil is more approaching around strength of wall body index and the cut-pff wall, the stressed back of body of wall is strong with the compatible deformation ability of foundation soil, is not prone to cracking.Good (the water-intake rate ω of unit≤10 of anti-permeability performance in addition -6Cm/s), construction costs is lower (120~400 yuan/m 2), compare with the rigidity materials for wall, as the body of wall of antiseepage, flexible materials for wall has very big development potentiality merely.
The plastic concrete cut-pff wall it become wall technology to be: in groove section digging process, inject retaining wall with mud (also being referred to as stable liquid) in groove; When the grooving end of job, by pumping into method the plastic concrete mixture is sent in the groove, and the existing mud in the groove is replaced.The plastic concrete cut-pff wall is complex process not only, can not utilize existing mud in the groove, slurry material preparation cost height, and the mud waste is serious, and groove section quality of connection is relatively poor.
Self-solidifying mortar cut-pff wall is that in the underground diaphragm wall digging process, it plays slurry coat method with cement, wilkinite, retardant and the formulated a kind of slurries of water, and after the slotted eye excavation was finished, slurries condensed into low intensive flexible body of wall voluntarily.Because the uncertainty of antiseepage wall chase section digging time has not often been excavated in the unit groove section, condensation cure has taken place in mortar in the groove.Therefore, self-solidifying mortar cut-pff wall is not easy to site operation, and materials for wall is impervious relatively poor.
Summary of the invention
One of purpose of the present invention is to provide a kind of low cost, pollution-free, cut-off wall slurry material that anti-permeability performance is good.
Another object of the present invention provides the simple cut-pff wall wall building technique of a kind of technology.
The technical scheme that realizes the present invention's first purpose is: a kind of cut-off wall slurry material comprises retaining wall mud and the original mortar of curing; Wherein retaining wall has following components by part by weight with mud: 30~150 parts of swelling scholar or clays, 1~12 part of soda ash, 0.1~1.5 part of selective flocculant, 0.5~8.0 part of water retaining, 860~980 parts in water; Solidify and have following components by part by weight: 180~400 parts of silicate cements, 100~500 parts of sands, 25~120 parts in flyash, 16~80 parts of water glass, 0.2~2.0 part of the poly-type water reducer of resistance, 0.1~1.0 part of linking agent, 80~240 parts in water with original mortar.Water glass component wherein adds at twice: add 40%~60%, remaining 60%~40% during the preparation mortar and add after the pore-creating of groove section finishes.
Described retaining wall is 0.5: 1~0.9: 1 with mud with the mixed volume ratio that solidifies with original mortar unit prescription.
Described retaining wall with the selective flocculant in the mud be molecular weight greater than 1,500,000, the hydro-polyacrylamide of degree of hydrolysis about 30%; Water retaining is CMC (Sodium Carboxymethyl Cellulose) BP/USP or hydrolyzed polyacrylonitrile.Described curing is naphthalenesulfonate polycondensate or iron network sulfonated lignin with the poly-type water reducer of the resistance in the original mortar; Linking agent is an inorganic aluminate, preferably sulfuric acid aluminium.
The technical scheme that realizes another purpose of the present invention is: a kind of wall building technique is characterized in that having following steps:
1. in the unit groove section digging process of cut-pff wall, in groove, inject retaining wall mud;
2. in the trenching construction latter stage of unit groove section, progressively in the groove in the mud admixture solidify and use original mortar, realize when the chute forming machine digging in the groove that existing mud and curing are with the first mixing of original mortar; Described retaining wall has following components by part by weight with mud: 30~150 parts of wilkinite or clays, 1~12 part of soda ash, 0.1~1.5 part of selective flocculant, 0.5~8.0 part of water retaining, 860~980 parts in water; Described curing has following components by part by weight with original mortar: 180~400 parts of silicate cements, 100~500 parts of sands, 25~120 parts in flyash, 8~40 parts of water glass, 0.2~2.0 part of the poly-type water reducer of resistance, 0.1~1.0 part of linking agent, 80~240 parts in water;
3. after the pore-creating of groove section finishes, add 8~40 parts of water glass again, the final uniform mixing of all slurries in mechanical stirring or pressurized air stir back realization groove forms the body of wall of cut-pff wall in condensation cure in the time.Described condensation cure time≤24h.
