Description
Technical field
The present invention relates to a kind of perpendicularity is good, resistance to tilting is good, have bearing capacity at full capacity triangle Flos Mume cement mixing method and manufacturing process, belong to cement drilled pile and manufacture field.
Background technology
CN1632233 A, title " the one-tenth pile operation method of bidirectional stirring pile ", a: leveling place；B: bidirectional stirring pile machine positions: crane suspention blender is to referring to fixed pile centering；C: stirring is sunk: start bidirectional stirring pile machine, makes bidirectional stirring pile driver drilling rod along leading truck to incision soil, opens and send stock pump, the blade of forward and reverse rotation respectively Stirring soil cement simultaneously on soil body water-spray type slurry, bidirectional stirring pile driver drilling rod；D: bidirectional stirring pile driver drilling rod persistently sinks and stirring concrete earth, until projected depth；E: while stirring promotes, the blade of forward and reverse rotation on bidirectional stirring pile driver drilling rod continues stirring concrete earth；F: promote, be stirred to earth's surface or the above 50cm of designed elevation, complete the construction of two-way stirring cement mixing method.Its weak point: one is that the stake of background technology molding is still for single-column cement earth pile, be in the single-column cement earth pile of soft soil foundation owing to pile foundation area is little, stake surrounding soil property is dilute soft, vertical be not enough to support single-column cement earth pile by support force and keep vertically, thus easily causes the single-column cement earth pile run-off the straight of institute's molding to scrap；Two be due in single-column cement earth pile the stirring of cement mortar and soil for stir in the same direction, it is impossible to make the mixing between cement mortar and soil be unable to reach uniformly, thus the single-column strength of the cement-soil piles of institute's molding certainly will be caused low.
Summary of the invention
Purpose of design: avoid the weak point in background technology, designs a kind of perpendicularity is good, resistance to tilting is good, have bearing capacity at full capacity triangle Flos Mume cement mixing method and manufacturing process.
Design: in order to realize above-mentioned purpose of design.1, the both ends of the surface of cement mixing method and pile body are connected by three Flos Mume petals the design constituted, and are one of the technical characteristics of the present invention.So purpose of design is: due to the pile foundation (stake end face) of the cement mixing method of the application in Bougainvillea spectabilis flower-shape, the overall structure that is made up of three Flos Mume petals that angle is the most equal of pile body, the not only supporting surface of pile foundation stable support big, triangular in shape, and the pile body being in weak soil is that the triangle legs of the tripod mutually supports due to formed, thus efficiently solve the defect that single-column cement earth pile easily tilts.2, the three axle rod bits control by controller, makes the design rotated between three axle drilling rods with mutually opposite direction, be the present invention technical characteristic two.So purpose of design is: owing to the three axle rod bits of the application are along the stirring of sinking limit, leading truck limit, limit whitewashing, its sinking mixing direction is contrary, it is thus able to make that cement mortar and soil are full and uniform to combine together, solve the defect that the cement mortar of background technology existence is low with the pile intensity that soil stirring inequality is caused, make the cement mixing method of institute's molding have the advantages that perpendicularity is good, intensity is high.3, have between multi-turn lobe the design of distribution in spacing on three Flos Mume cement mixing method pile bodies, be the present invention technical characteristic three.So purpose of design is: it is protruding that the spacing at three Flos Mume cement mixing method pile bodies is provided with hoop, both just as the reinforcement of pile body, platform is supported again just as a circle, not only increase the coefficient of friction between pile body and ground, effectively carry the bearing capacity setting pile body, and make the bearing strength of stake be effectively improved.
Technical scheme 1: a kind of triangle Flos Mume cement mixing method, including cement mixing method, the both ends of the surface of described cement mixing method and pile body are connected by three Flos Mume petals and constitute.
Technical scheme 2: the manufacturing process of a kind of triangle Flos Mume cement mixing method, on the basis of background technology cement mixing pile construction method: 1) by three axle boring bar mixing pile machine location of Triangle-Profile, centering, leveling；After putting triangle mixing pile stake position well, shifting dynamic triaxial boring bar mixing pile machine, to triangle mixing pile position, centering, uses level gauge leveling；2) adjusting leading truck perpendicularity: use theodolite or ceiling hammer double-direction control leading truck perpendicularity, perpendicularity is long less than 1.0%；3) mixing serosity in advance: deep mixer stirs sinking simultaneously in advance, backstage mixing cement grout, before treating mud jacking, serosity is put in aggregate bin, select cement grade 425# common silicate cement mixing serosity, the ratio of mud controls in 0.45～0.50 scope, requires that every meter of deep-mixed pile cement consumption is no less than 120Kg according to design；4) stirring is sunk: start tri-axial deep stirring pile machine rotating disk, after head rotating speed to be mixed is normal, while making three axle rod bits be rotated with mutually opposite direction by controller, three axle rod bits stir along sinking limit, leading truck limit, limit whitewashing, make serosity and the soil body stir；5) after tri-axial deep stirring pile machine sinks to projected depth, whitewashing repeats stirring and promotes, and is promoted to ground always, can form triangle Flos Mume cement mixing method.
The present invention compared with background technology, one be the blossom type cement earth pile of angular distribution owing to the loaded area of pile foundation is big, carrying strong point distribution triangular in shape, thus the good stability of pile foundation；Two is the pile body being made up of triangle Flos Mume petal when being in soft soil foundation, and the equal three Flos Mume petal pile bodies of its angle act on soft soil foundation wall just as three post projection fore-sets, it is ensured that cement earth pile does not tilts in soft soil foundation, stands vertically；Three is owing to three axle rod bits are along the stirring of sinking limit, leading truck limit, limit whitewashing, its in opposite direction of stirring of sinking, it is thus possible to make that cement mortar and soil are full and uniform to combine together, it is ensured that the pile strength height of institute's molding cement earth pile.
