Abstract

The present invention relates to an antifreeze slurry preparation method, and antifreeze slurry is used in slurry retaining wall cast-in-place pile construction. The antifreeze slurry preparation method comprises the following steps: adding 30 to 35% of NaCl into a quantitative amount of clean water to prepare a saturated aqueous NaCl solution, and then putting the saturated aqueous NaCl solution into a slurry mixing vessel; adding sodium bentonite in the proportion of 6 to 8%, and evenly stirring to prepare slurry; adding a polyanionic cellulose thickener in the proportion of 0.01 to 0.05% into the slurry; adding a Na2CO3 dispersant into the slurry, and adjusting the adding dosage of the Na2CO3 dispersant to 0.3 to 0.5 %, and controlling slurry PH to 6-8; adding an organic antifreeze slurry additive in the proportion of 0.15 to 0.30% into the slurry, fully stirring for not less than 5min, filling the slurry into a slurry pool, and stirring with a slurry mixer; and storing for 24h to obtain the finished product antifreeze slurry. The antifreeze slurry preparation method solves antifreezing problems in e slurry preparation and using process, and meets construction requirements in winter.

Description

The preparation method of antifreeze mud
Technical field
The present invention relates to antifreeze mud, the preparation method of the antifreeze mud of specifically using in a kind of slurry drilled pile construction.
Background technology
At present, pile foundation is widely adopted in ground foundation engineering, and slurry drilled pile has applicability widely in a lot of different geological conditions, pile body diameter is generally larger, single pile bearing capacity is higher, it is one of pile foundation form the most frequently used in pile foundation, utilize mud circulation around hole wall, to form the mud protective surface of uniformity, mud in stake hole has certain proportion, can stop stake hole underground water around to permeate in stake hole, prevent that the hole wall earthwork from caving in, until whole hole is lowered to bored concrete pile pile body steel reinforcement cage, with concreting method under water, make mud all discharge a Kongzui end form by concrete from evenly rising at the bottom of stake and become closely knit pile body. when winter construction, need be incubated processing to slurrying and the circulatory system, working measure expense is higher.
Summary of the invention
When the object of the invention is to solve winter construction, in slurrying process, prepare mud by antifreeze mud proportioning, solve antifreeze in slurrying and use procedure, improve the service behaviour of mud, make mud there is very strong solid phase particles suspending power, mobility, meet the requirement of construction in the winter time.
The technical scheme that the present invention solves its technical problem employing is:
A preparation method for antifreeze mud, carries out in the steps below:
(1) in quantitative clear water, add 30～35% NaCl, make the saturated NaCl aqueous solution, then put into mud mixing device; Add sodium bentonite in 6～8% ratio again, stir, make mud;
(2) in mud, add polyanion cellulose tackifier in 0.01～0.05% ratio;
(3) in mud, add Na2CO3Dispersant, adjusts Na2CO3The volume of dispersant is 0.3～0.5%, and the PH that controls mud is 6～8;
(4) in mud, add organic antifreeze mud additive in 0.15～0.30% ratio, fully stir and be no less than after 5min, mud is injected to mud pit, and stir with slurry mixer; After storage 24h, be the antifreeze mud of finished product.
Further, sodium bentonite is taking montmorillonite as main sodium bentonite.
Further, organic antifreeze mud additive is taking sulfonated-pheno-formoldehyde resin, ethylene glycol as main organic antifreeze mud additive.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
While carrying out slurry drilled pile construction winter, reduce the measure cost that mud insulation is produced, accelerate speed of application, improve construction quality.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further elaborated, but embodiment does not form any restriction to the present invention.
The preparation method of the antifreeze mud described in the present embodiment, carries out in the steps below:
(1) in 100Kg clear water, add 32KgNaCl, make the saturated NaCl aqueous solution, then put into mud mixing device; Add again 8Kg taking montmorillonite as main sodium bentonite, stir, make mud;
(2) in mud, add 0.05Kg polyanion cellulose tackifier, stir;
(3) in mud, add 0.4KgNa2CO3Dispersant, stirs, and the PH that makes mud is 7.5;
(4) in mud, add 0.2Kg taking sulfonated-pheno-formoldehyde resin, ethylene glycol as main organic antifreeze mud additive, stir after 5min, mud is injected to mud pit, and stir with slurry mixer; After storage 24h, be the antifreeze mud of finished product.
