Abstract
The utility model relates to an inversed Y-type single-row unidirectional rotary spraying, mixing and reinforcing combined tangent pile, which comprises a foundation pit, wherein a single-row vertical rotary spraying, mixing and reinforcing piling wall is arranged on the soil body at the periphery of the foundation pit, a unidirectional rotary spraying, mixing and reinforcing expanded inclined pile which is slantly inserted into the soil body is arranged at one side of the foundation pit, the top end of the unidirectional rotary spraying, mixing and reinforcing expanded inclined pile is connected and fixed with the top end of the single-row vertical rotary spraying, mixing and reinforcing piling wall through a beam, and anchor bars are buried in both the single-row vertical rotary spraying, mixing and reinforcing piling wall and the unidirectional rotary spraying, mixing and reinforcing expanded inclined pile. The utility model adopts the unidirectional rotary spraying, mixing and reinforcing expanded inclined pile which is slantly inserted into the soil body to substitute the traditional inner support, does not occupy the space of the foundation pit, and has convenient construction. Profile steels or prestressed strands and other anchor bars are added into the single-row vertical rotary spraying, mixing and reinforcing piling wall and the unidirectional rotary spraying, mixing and reinforcing expanded inclined pile to form a reinforcement cement pile body, so the bending resistance and shearing strength of the tangent pipe and an anchor pipe are greatly improved, and the function of increasing the supporting is better played.
Description
Technical field
The utility model relates to a kind of architectural engineering pit supporting, be particularly related to the stake of a kind of chevron shaped single unidirectional rotary jet stirring reinforcement combination supporting, be applicable to that the soil layers such as sand, cohesive soil, silt, miscellaneous fill, loess, mud and mucky soil and the degree of depth are not more than 6 meters foundation ditch.
Background technology
In building operations, the supporting of foundation ditch comprises that mainly support in the foundation ditch, concrete support, bolt support, supports owing to be located in the foundation ditch in the foundation ditch, and cost is higher, influences construction shoveling progress, and tears support, support replacement trouble open, uses less.The concrete safety is good, but mainly has following shortcoming: because the foundation ditch planar range is big, so concrete backing material consumption is big, need add stand column pile, lattice column etc., it is higher to support cost, and shoveling speed is influenced, the earthwork often needs repeatedly to turn over fortune, influences the duration; Increase and to tear support, support replacement technology and time open, and it is in a single day unreasonable to tear the support support replacement open, except that may causing foundation pit side-wall distortion increase, may also can exert an influence to agent structure.And bolt support can be carried out anchor bolt construction along with soil excavation, organizes under the situation anchor pole curing time can eliminate fully in reasonable excavation, and therefore the top speed of application is fast; Though the anchor pole system relies on integral body unlike support system, can according to circumstances carry out soil excavation and bottom slab concreting flexibly, but in the higher stratum of flour sand, silt or groundwater table,, there is certain limitation because the pore-creating meeting of anchor pole causes sandblast to be leaked and problem such as the hole of collapsing.
The utility model content
The technical problems to be solved in the utility model provides the stake of a kind of chevron shaped single unidirectional rotary jet stirring reinforcement combination supporting, and supporting effect is good, can reduce the cost of foundation pit enclosure structure, makes spaciousness in the foundation ditch, improves the construction operation condition.
For solving the problems of the technologies described above, the technical solution of the utility model is: the stake of a kind of chevron shaped single unidirectional rotary jet stirring reinforcement combination supporting, comprise foundation ditch and the foundation ditch soil body all around, its innovative point is: the soil body around the described foundation ditch is provided with single vertical rotary jet stirring reinforcement piling wall, be provided with the oblique unidirectional rotary jet stirring reinforcement that stretches into down in the soil body in this single vertical rotary jet stirring reinforcement piling wall one side and expand a taper pile, the top that described unidirectional rotary jet stirring reinforcement expands a taper pile is connected and fixed by lintel with single vertical rotary jet stirring reinforcement piling wall top, and all is embedded with dowel in a described single vertical rotary jet stirring reinforcement piling wall and the unidirectional rotary jet stirring reinforcement expansion taper pile.
Further, described dowel can be steel strand, reinforcing bar or shaped steel.
Advantage of the present utility model is: the soil body around the foundation ditch adopts single vertical rotary jet stirring reinforcement piling wall, and the unidirectional rotary jet stirring reinforcement of going in the soil body with oblique cutting expands a traditional internal support of taper pile replacement, can not take foundation ditch space, convenient construction.Expand dowels such as increase shaped steel or prestress wire in the taper pile at single vertical rotary jet stirring reinforcement piling wall and unidirectional rotary jet stirring reinforcement, form the reinforced cement earth pile body, bending resistance, the shear strength of soldier pile and anchoring pile have been improved greatly, played the effect that increases supporting, be applicable to that the soil layer such as sand, cohesive soil, silt, miscellaneous fill, loess, mud and mucky soil and the degree of depth are not more than 6 meters foundation ditch.
Description of drawings
Accompanying drawing is the chevron shaped single unidirectional rotary jet stirring reinforcement combination supporting pilework schematic diagram of the utility model.
The specific embodiment
As shown in drawings, the utility model comprises the soil body 2 around foundation ditch 1 and the foundation ditch 1, on the soil body 2 around the foundation ditch 1, be provided with single vertical rotary jet stirring reinforcement piling wall 3, insert shaped steel or the prestress wire 4 that improves bending resistance, shear strength in the single vertical rotary jet stirring reinforcement piling wall 3, single vertical rotary jet stirring reinforcement piling wall 3 is provided with the unidirectional rotary jet stirring reinforcement expansion taper pile 5 that oblique cutting is gone into the soil body 2 away from a side of foundation ditch 1, is embedded with two prestress wires 6 in this unidirectional rotary jet stirring reinforcement expansion taper pile 5.
It all is the cement soil piles that with the rotary jet stirring method cement paste and soil layer fully mixed formation in soil layer that above-mentioned single vertical rotary jet stirring reinforcement piling wall 3 and unidirectional rotary jet stirring reinforcement expand a taper pile 5, both tops are connected and fixed by lintel 7, and the top of prestress wire 4,6 is fixing by prestressed anchor 8,9 and lintel 7.
Claims (2)
1. chevron shaped single unidirectional rotary jet stirring reinforcement combination supporting stake, comprise foundation ditch and the foundation ditch soil body all around, it is characterized in that: the soil body around the described foundation ditch is provided with single vertical rotary jet stirring reinforcement piling wall, be provided with the oblique unidirectional rotary jet stirring reinforcement that stretches into down in the soil body in this single vertical rotary jet stirring reinforcement piling wall one side and expand a taper pile, the top that described unidirectional rotary jet stirring reinforcement expands a taper pile is connected and fixed by lintel with single vertical rotary jet stirring reinforcement piling wall top, and all is embedded with dowel in a described single vertical rotary jet stirring reinforcement piling wall and the unidirectional rotary jet stirring reinforcement expansion taper pile.
