Technical Field
The utility model belongs to the technical field of foundation pit supporting equipment, and particularly relates to a prestressed special-shaped high-strength hollow supporting pile.
Background
The existing deep foundation pit support mostly adopts the modes of pouring slope protection piles and connecting walls to carry out support, steel reinforcement cages are required to be processed on site, and then the slope protection piles and the connecting walls are poured on site. The construction method has poor construction quality, unevenness, various environmental pollution problems in site construction, such as electric welding light pollution, slurry pollution, tail gas pollution, noise pollution and the like, and deep foundation pit supporting also adopts a mode of inserting steel sheet piles, such as inserting SMW and Larsen steel sheet piles, but the two types of steel piles have small rigidity and large deformation in the excavation process of the foundation pit, so that the construction quality of the foundation pit is difficult to ensure.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides the prestressed special-shaped high-strength hollow support pile which is simple in structure and low in cost, can facilitate the operation of foundation pit support and ensure the construction quality of the foundation pit.
The technical scheme adopted by the utility model is as follows: a prestressed special-shaped high-strength hollow support pile comprises a pile body, wherein the pile body is of a columnar structure, and a circular through hole is formed in the center of the pile body; the cross section of the pile body is hexagonal, and opposite sides of the hexagon are parallel; a group of opposite ridges of the column body are respectively provided with a V-shaped groove.
In the prestressed special-shaped high-strength hollow support pile, the pile body is made of concrete, and the strength grade of the concrete is C60-C80.
In the prestressed special-shaped high-strength hollow support pile, the length of the pile body is 12000-18000 mm.
In the prestressed special-shaped high-strength hollow support pile, a reinforcement cage is arranged in the side wall of the pile body; the reinforcement cage comprises a plurality of threaded reinforcements, a plurality of PC steel bars and a spiral stirrup; a plurality of twisted steel bars and a plurality of PC steel bars are respectively bound on the inner sides of the spiral stirrups; the twisted steel bar and the PC steel bar are arranged along the axis of the pile body.
Compared with the prior art, the utility model has the beneficial effects that: the utility model has simple structure, the bending rigidity in the length direction is larger than that of the circular section with the same diameter, and the utility model can replace circular support piles and various types of steel sheet piles for supporting. The utility model improves the construction efficiency of the foundation pit support, can ensure quick construction, saves the construction period, is convenient to construct, saves raw materials, reduces the construction cost, and reduces the environmental pollution by member production capacity.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in FIG. 1, the utility model includes a pile body 1, the pile body 1 is a columnar structure, a circular through hole 11 is arranged at the center of the pile body 1, and the diameter of the through hole 11 is 400-550 mm. The section of the pile body 1 is hexagonal, and opposite sides of the hexagonal are parallel. A group of opposite ridges of the column body 1 are respectively provided with a V-shaped groove 12. A reinforcement cage is arranged in the side wall of the pile body 1; the reinforcement cage comprises a plurality of threaded reinforcements 13, a plurality of PC steel bars 14 and a spiral stirrup 15; the plurality of twisted steel bars 13 and the plurality of PC steel bars 14 are respectively bound on the inner sides of the spiral stirrups 15; the twisted steel 13 and the PC steel bar 14 are arranged along the axis of the pile body 1. The pile body 1 is made of concrete, and the strength grade of the concrete is C60-C80. The length of the pile body 1 is 12000-18000 mm.
The pile body reinforcing steel bar support is used for replacing the existing circular slope protection pile, the length standard of each pile body is 12-18 m, the concrete strength grade is C60 and C80, and the number of the threaded steel bars 13 and the number of the PC steel bars 14 of the pile body reinforcing steel bars are determined according to the calculation of a support structure. According to the geological conditions and the design condition of the foundation pit, the corresponding section size and the reinforcement condition are selected by calculating and comparing the flexural rigidity, the area, the weight and the like.
The utility model is produced in a prefabricated part factory, the quality is ensured, the environmental pollution is less, after the production is finished, the qualified product is firstly inspected after the standard strength is reached, and after the standard strength is qualified, the product is transported to a construction site in batches for on-site construction. During on-site construction, the soil can be stirred by using a stirring pile device (such as a triaxial stirring pile, a TRD device and the like), and the stirring pile is used as a hole site of a precast pile and a waterproof curtain.
The static pressure machine and the hammering machine are used for construction, the soil squeezing effect is noticed during construction, and the construction must be accurately positioned. When two piles are butted, two channel steel are used for connecting according to a preset reserved hole, and then high-strength bolts are used for fastening, so that the upper pile and the lower pile form a whole with high bending rigidity, and the rest is done by analogy, and the next procedure circulation is carried out. And after the slope protection pile is constructed, performing crown beam construction, wherein the crown beam construction adopts a currently common method, and after the crown beam construction is finished, excavating soil inside a foundation pit, and constructing by adopting an inner support, an anchor rod, a cantilever and the like.
