Description
Technical field
The utility model relates to the quincunx Soil-cement high strength bearing peg that good, the anti-tilt capability of a kind of verticality is good, have supporting capacity at full capacity, belongs to cement drilled pile and manufactures field.
Background technology
CN1632233 A, title " the one-tenth pile operation method of bidirectional stirring pile ", a: leveling place; B: bidirectional stirring pile machine is located: crane suspention mixer is to referring to fixed pile and centering; C: stir: start bidirectional stirring pile machine, makes bidirectional stirring pile driver drilling rod native along leading truck to incision, opens and send stock pump, to soil body water-spray type slurry, and the blade Stirring cement-soil simultaneously of forward and reverse rotation respectively on bidirectional stirring pile driver drilling rod; D: bidirectional stirring pile driver drilling rod continues to sink and stirring concrete earth, until projected depth; E: stir while promoting, 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 design elevation, complete the construction of two-way stirring cement mixing method.Its weak point: one be the shaping stake of background technology is still single-column cement earth pile, the single-column cement earth pile being in soft foundation because pile foundation area is little, stake surrounding soil property is rare softly, vertical is not enough to support single-column cement earth pile by support force and keeps vertically, thus very easily causing shaping single-column cement earth pile run-off the straight and scrapping; Two is because cement paste in single-column cement earth pile and native stirring are for stir in the same way, mixing between cement paste with soil cannot be made cannot to reach even, shaping single-column strength of the cement-soil piles thus certainly will be caused low.
Utility model content
Purpose of design: avoid the weak point in background technology, designs the quincunx Soil-cement high strength bearing peg that good, the anti-tilt capability of a kind of verticality is good, have supporting capacity at full capacity.
Design scheme: in order to realize above-mentioned purpose of design.1, the both ends of the surface of cement mixing method and pile body to be connected the design formed by many plum blossom petals, are one of technical characteristics of the present utility model.The object of such design is: the overall structure that the pile foundation (stake end face) due to the cement mixing method of the application is made up of the many plum blossom petals that angle is mutually equal in polygonal quincunx, pile body, not only the supporting surface of pile foundation large, in polygonal stable support, and the pile body be in weak soil is that the polygonal legs of the tripod supports mutually due to what formed, thus efficiently solves the defect that single-column cement earth pile very easily tilts.2, multi-drill rod bit is by the control of controller, and making with the design that mutually opposite direction is rotated between multiaxis drilling rod, is technical characteristic two of the present utility model.The object of such design is: because the multi-drill rod bit of the application is along the stirring of sinking limit, leading truck limit, limit whitewashing, its sinking mixing direction is contrary, thus cement paste can be made and soil is full and uniform combines together, solve the cement paste that background technology exists and stirs the low defect of the pile intensity that causes of inequality with soil, shaping cement mixing method is had verticality is good, intensity is high feature.3, one or more concrete cement stake being positioned at the design of quincunx Soil-cement high strength carrying pile body, is technical characteristic three of the present utility model.The object of such design is: when one or more concrete cement stake being pressed into quincunx Soil-cement high strength carrying pile body, not solidified soil cement slurry internally will coatedly for concrete pile solidify, externally extrude weak soil, the compactness of weak soil is increased, significantly enhance the bearing capacity of weak soil to cement mixing method, and then increase the bearing capacity of concrete pile.
Technical scheme: a kind of quincunx Soil-cement high strength bearing peg, comprise cement mixing method, the both ends of the surface of described cement mixing method and pile body are connected by many plum blossom petals and form, and one or more concrete cement stake is positioned at quincunx Soil-cement high strength carrying pile body.
The utility model is compared with background technology, and one is that the blossom type cement earth pile of polygonal distribution is because the loaded area of pile foundation is large, bearing support point is quincunx distribution, the thus good stability of pile foundation; Two is pile bodies be made up of polygonal plum blossom petal when being in soft foundation, and the many plum blossom petal pile bodies that its angle is equal act on soft foundation wall just as the protruding fore-set of multicolumn, ensure that cement earth pile does not tilt in soft foundation, stand vertically; Three be due to multi-drill rod bit stir along sinking limit, leading truck limit, limit whitewashing, its direction sinking to stirring is contrary, thus can make cement paste and soil is full and uniform combines together, ensure that the pile strength of shaping cement earth pile high.
