Abstract
The utility model relates to a double-shaft drilling interlocking fender pile wall capable of rotating and lateral force resistance comprises pile bodies and an enclosure wall body. A double-shaft interlocking drilling cast-in-place pile is formed by interlocking two pile bodies, and the axial plane of the cast-in-place pile is perpendicular to the fender axis after localized rotation and is in the same direction with the lateral force of soil bearing. Bearing reinforcements are disposed at two circular ends of the double-shaft interlocking drilling cast-in-place pile, and constructing reinforcements are disposed in the middle of the cast-in-place pile. The fender pile has the advantages that the double shaft interlocking pile body is perpendicular to the fender axis after panel localized rotation with 90 degrees to be kept in the same direction with that of the lateral force of soil bearing, compared with the traditional drilling round head piles and the improved interlocking piles, bend resistant capacity is increased about 200%, intensity of the fender wall is increased about 500% and engineering manufacture cost is reduced about 50%, which belongs to drilling cast-in-place piles the double-shaft interlocking piles, and is adaptable for various support engineering and slope stabilization engineering of various soil. Further, the enclosure wall body is high in lateral force resistance, low in manufacture cost and fast in construction speed.
Description
Technical field
The utility model relates to building engineering field, and especially a kind of rotatable twin shaft boring interlock lateral force resistance is gone along with sb. to guard him piling wall.
Background technology
At present in bracing of foundation pit engineering and the stability of slope engineering, single drill-pouring campshed is the common form of going along with sb. to guard him, keep off native water-stop curtain in conjunction with cement mixing pile, rotary churning pile or high-pressure slip-casting, form the enclosure wall of sealing, this retaining wall has shortcomings such as speed of application is slow, cost height.In recent years developed boring interlock campshed technology, utilized the boring campshed of interlock to form the enclosure wall that seals, also there are shortcomings such as cost height, construction quality instability in this retaining wall.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provide a kind of rotatable twin shaft boring interlock lateral force resistance to go along with sb. to guard him piling wall, this interlock twin shaft stake can be along the walking construction of bracing of foundation pit limit, also can optionally carry out 360 ° of rotations of plane positioning, the pile body flexural strength is increased, reach and strengthen the anti-side strength and stiffness of enclosure wall, the purpose of minimizing construction costs.
The utility model solves the technical scheme that its technical problem adopts: this rotatable twin shaft boring interlock lateral force resistance is gone along with sb. to guard him piling wall, comprise pile body and enclosure wall body, form twin shaft interlock bored pile by two pile body interlocks, after its axial plane position rotating with go along with sb. to guard him axis normal, native lateral pressure direction is consistent with being subjected to; Two circles two at twin shaft interlock bored pile disposes principal rod, in intermediate configurations the structure muscle is arranged.
Enclosure wall bodily form formula can be arranged at intervals with plain concrete twin shaft interlock stake along going along with sb. to guard him axis direction, sets rotation in the centre and goes along with sb. to guard him axis and become twin shaft interlock bored pile after 90 °, forms the anti-side wall of going along with sb. to guard him that seals.
Enclosure wall bodily form formula also can be provided with the cement-soil curtain along going along with sb. to guard him axis direction, sets at interval rotation then and goes along with sb. to guard him axis and become twin shaft interlock bored pile after 90 °, forms the anti-side wall of going along with sb. to guard him that seals.
The effect that the utility model is useful is: with twin shaft interlock pile body plane positioning half-twist, make and go along with sb. to guard him axis normal, native lateral pressure direction is consistent with being subjected to, so compare traditional boring circle stake and the interlock stake of exploitation recently, bending resistance improves about 200%, it is about 500% that enclosure wall rigidity improves, and saves construction costs about 50%.Rotation twin shaft interlock stake of the present utility model belongs to bored pile, and what be fit to various soil properties in principle goes along with sb. to guard him engineering and stability of slope engineering; The anti-side ability of retaining wall is strong, cost is low, speed of application is fast.

Description of reference numerals: pile body 1, principal rod 2, structure muscle 3 is gone along with sb. to guard him axis 4.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1: as depicted in figs. 1 and 2, this rotatable twin shaft boring interlock lateral force resistance is gone along with sb. to guard him piling wall, comprise pile body 1 and enclosure wall body, (adopt mud off technology to become the interlock double circular hole by two pile body 1 interlock formation twin shaft interlock bored piles, place the reinforcing cage of two pile bodies, water the concrete pile under water).With to go along with sb. to guard him axis 4 vertical, native lateral pressure direction is consistent with being subjected to after the stake axial plane position rotating; Two circles two at twin shaft interlock bored pile disposes principal rod 2, in intermediate configurations structure muscle 3 is arranged, and so can significantly improve the bending resistance and the bending rigidity in interlock stake cross section, reaches the reduction cost, strengthens the purpose of the anti-side rigidity of retaining wall.Wherein, stake footpath D can be between 400～1500mm value, interlock pile spacing L can be between 300～1400mm value.Described enclosure wall bodily form formula is to set the plain concrete deposited interlock stake of twin shaft along going along with sb. to guard him axis 4 directions, sets rotation then and goes along with sb. to guard him axis and become twin shaft interlock bored pile after 90 °, and overlap joint forms the piling wall of going along with sb. to guard him that seals.
Utilize the twin shaft stake machine that plane positioning can 360 ° of rotations, once form two circle stakes of interlock, the direction that can change the twin shaft stake along the foundation ditch limit as required flexibly be subjected to force direction consistent, resistance to lateral bending and rigidity are increased, reach the purpose that reduces construction costs.
Embodiment 2: as shown in figures 1 and 3, difference from Example 1 is: described enclosure wall bodily form formula is to set cement earth pile curtain (curtain that cement mixing pile, rotary churning pile or high-pressure slip-casting form) along going along with sb. to guard him axis earlier, set rotation then and go along with sb. to guard him 90 ° of twin shaft interlock bored piles of axis formation, form the piling wall of going along with sb. to guard him of sealing, the relative position of cement earth pile curtain and interlock drilled pile is set as required.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of the stake clipping edge shape formation of replacement or equivalent transformation implantation, all drop on the protection domain of the utility model requirement.
