Description
Technical field
The invention belongs to technical field of buildings, relate to a kind of cement mixing method and manufacturing process thereof, particularly relate to a kind of Triangular Flos Mume shape cement mixing method and manufacturing process thereof.
Background technology
Cement mixing method is a kind of method for reinforcing the low ground of saturated soft clay, it utilizes cement as curing compound, by special Mixing Machine, in ground depths by weak soil and curing compound action of forced stirring, utilize the series of physical chemical reaction produced between curing compound and weak soil, weak soil is hardened into have the high-quality ground of globality, water stability and some strength.But existing cement mixing method is all single-column stake, when the higher uplift resistance of needs and compressive resistance, need the aperture of boring to do large thus make the boring post of larger aperture.
The manufacturing process of existing cement mixing method comprises the following steps:
1 position of p ile machine, centering, leveling.After putting agitation pile stake position well, mobile mixing pile machine arrives and refers to fixed pile, centering, leveling level gauge leveling.
2 adjustment leading truck verticality.Adopt transit or ceiling hammer double-direction control leading truck verticality.By design and code requirement, verticality be less than 1.0% long.
3 mixing slurries in advance.Deep mixer stirs simultaneously in advance, and slurries are put into aggregate bin before treating mud jacking by backstage mixing cement grout.Select cement grade 425# common silicate cement mixing slurries, water/binder ratio controls in 0.45 ~ 0.50 scope, is no less than 50Kg according to designing requirement every meter deep-mixed pile cement consumption.
4 stir.Start deep-mixing pile driver rotating disk, after head rotating speed to be mixed is normal, drilling rod can be made to stir along sinking limit, leading truck limit, and subsidence velocity regulates and controls by gear, and operating current should not be greater than rated value.
5 whitewashings are stirred and are promoted.After sinking to arriving projected depth, open mortar pump, send slurry to stirring-head grout outlet by pipeline, after pulp, start mixing pile machine and tensioning chain device, stir limit lifting drilling rod by designing the hoisting velocity 0.50 ~ 0.8m/min limit whitewashing determined, slurries and the soil body are are fully mixed and stirred.
6 repeat to stir.Stirring drill bit is promoted to after stake pushes up above 500mm height, and close mortar pump, repeat stirring and sink down into projected depth, subsidence velocity is undertaken by designing requirement.
7 whitewashings repeat to stir and promote.After sinking to arriving projected depth, whitewashing repeats to stir and promotes, and is promoted to ground always.
8 machine displacements.Constructed after a pile, mobile stake machine, to next pile position, repeats the construction that above step carries out next pile.
As can be seen here, the construction method of existing cement mixing method is single making, and every pile is all cylindrical.
Deficiency is sent out in order to overcome prior art, people are through constantly exploring, propose various solution, as Chinese patent literature discloses a kind of one-tenth pile operation method [notification number: CN102943467A] of bidirectional stirring pile, cement mixing method is stirred by soil and cement paste and is formed, one width stirs wall and is made up of the cement mixing method of many vertical overlap joints mutually, several Soil-cement Walls overlap the longer Soil-cement Wall of formation mutually, every width Soil-cement Wall is made up of the cement mixing method that the six roots of sensation is vertical, the six roots of sensation cement mixing method same time is formed, six roots of sensation cement mixing method is on same vertical plane, adjacent pile body overlaps mutually, adjacent Soil-cement Wall overlaps mutually.
Such scheme can once be constructed six roots of sensation cement mixing method simultaneously, decrease the multiple tracks seam of former single shaft or the formation of two axle cement mixing methods, improve efficiency of construction, decrease the amount of labour used, compensate for the defects such as three axes agitating pile displacement soil is many, water/binder ratio is large, cement mixing content is large, shorten the construction period more than 2/3rds.But as described in the program, six roots of sensation cement mixing method is on same vertical plane, and therefore agitation pile linearly distributes thus forms the cement mixing method of planar shaped, the uplift resistance of this cement mixing method, intensity need to be improved further.
