Description
Technical field
The present invention relates to slurry coat method and its production method, in particular to a kind of pressure-bearing layer of sand pile pulling slurry coat method and its
Preparation method.
Background technique
During existing pressure-bearing layer of sand pile foundation is pulled out, frequently with mud off, for preventing hole wall collapse, lubricating machine
Tool, suspension boring mud, reduction friction etc..According to the difference for making pulp material ingredient and proportion mud can be divided into finely divided mud,
Rough segmentation dissipates the low solids mud, polymer unfixed phase slurry etc..Traditional bentonite slurry generally with its good economy and
Retaining wall effect is widely used.But it is directed to different geological conditions and underground regimen, the main work slurry material of bentonite slurry
Material and proportion can show very big difference, and retaining wall effect is poor, and sand content is big, and mud cake is thick, especially pile pulling when mud detached dowel
The effect of wall is poor, influences pile pulling quality.
Summary of the invention
Goal of the invention: it is an object of the present invention to provide a kind of pressure-bearing layer of sand pile pulling slurry coat method, slurry coat method retaining wall effects
Fruit is good, and pile pulling quality is high.It is a further object of the present invention to provide a kind of preparation methods of pressure-bearing layer of sand pile pulling slurry coat method.
Technical solution: pressure-bearing layer of sand pile pulling slurry coat method of the invention, the raw material including following parts by weight: bentonite
6.5~21.5 parts, 0.45~0.55 part of soda ash, 0.18~0.22 part of sodium carboxymethylcellulose, fatty alcohol polyoxyethylene ether 0.045
~0.055 part, 100 parts of water.
In above-mentioned technical proposal: carboxymethyl cellulose can enhance the viscosity of mud, reduce percentage of water loss, formed Bao Erjian,
The low filter cake of permeability, can make drilling machine obtain lower gel initial, make mud be easy to release the gas for being rolled in the inside, while sand
Grain is adsorbed on mud off quickly, to reduce sand factor；Sodium carboxymethylcellulose makees drilling slurry borehole cleaning agent, can prevent swollen
Profit soil is chemically reacted with various solubility salts, to ensure that the performance of mud；Fatty alcohol polyoxyethylene ether can increase
Add the finish on concrete pile lining；The main function of soda ash is the pH value of adjusting mud, and pH value crosses h, clay in mud
Grain is difficult to decompose, and viscosity reduces, and fluid loss increases, and mobility reduces, and when less than 7, can also drilling tool be made to be corroded, if pH value mistake
Greatly, then mud will penetrate into the clay of hole wall, soften hole wall surface, and cohesiveness weakens between clay particle, cause to crack
And make hole wall collapse, when pH value is 8~10, aquation film thickness can be increased, improve the colloidity and stability of mud, reduce and lose
Water.
Further, the pressure-bearing layer of sand pile pulling slurry coat method includes the raw material of following parts by weight: bentonite 9.5
~19.5 parts, 0.47~0.52 part of soda ash, 0.19~0.21 part of sodium carboxymethylcellulose, fatty alcohol polyoxyethylene ether 0.048~
0.053 part, 100 parts of water.
Further, the pressure-bearing layer of sand pile pulling slurry coat method includes the raw material of following parts by weight: bentonite
14.5 parts, 0.5 part of soda ash, 0.2 part of sodium carboxymethylcellulose, 0.05 part of fatty alcohol polyoxyethylene ether, 100 parts of water.
The preparation method of the pressure-bearing layer of sand pile pulling slurry coat method, includes the following steps:
(1) bentonite, soda ash, sodium carboxymethylcellulose, fatty alcohol polyoxyethylene ether and water are weighed in proportion, and blending is stirred
It mixes；
(2) extruding.
Further, the product after the blending stirs 4-5min in high-speed mixer.
Further, the extruding is will to stir product and be placed in container to stand 20-24h.
The utility model has the advantages that the present invention separates, pile lining, retaining wall effect are good, and pile pulling quality is high.The performance of mud is good, and specific gravity reaches
1.22g/cm3, funnel viscosity reaches 35s, and sand factor is down to 8%, cake thickness < 2mm.
