Abstract
A pile foundation of prestressed expansion, anti-pulling, quakeproof and groundwork soil treatment is characterized in that a concrete hoop is arranged at the round stone layer of a prestressed pipe pile body. At least four anti-pulling steel bars with hooks are arranged at the bottom of a prestressed pipe pile, to form a reinforced concrete expansion. The utility model uses the traditional construction of the pipe pile to form a reinforced concrete enlarged pile, thereby effectively raising the end bearing capability, the anti-pulling power and the carrying capacity, and enhancing the quakeproof performance. The piles consist of hollow concrete prestressed or nonprestressed piles provided with a plurality of smooth or indented planes with round, square, triangle, polygon and corrugated cross-sections.
Description
Technical field:
The utility model relates to pile for prestressed pipe, is the pile foundation that a kind of prestressing force expands head, resistance to plucking, shockproof, double foundation soil processing.
Background technology:
The tradition pile for prestressed pipe is no matter squeeze into formula or forced, and is all little because of the bottom section, and the end load is very undesirable.Be to obtain bigger bearing capacity, often very dark pile driving construction so, just increased the pile foundation cost.
Summary of the invention:
The purpose of this utility model is to propose the pile foundation that a kind of prestressing force expands head, resistance to plucking, shockproof, double foundation soil processing, and it uses traditional tube pile construction to become the steel concrete expanded head pile, has effectively improved end load, uplift resistance, bearing capacity and enhancing shockproof properties.
The purpose of this utility model reaches by following technical measures:
A kind of prestressing force expands the pile foundation of head, resistance to plucking, shockproof, double foundation soil processing, being in the gravel layer position on the pile body of pile for prestressed pipe, thickness is arranged is 50mm, it highly is the concrete ring of 400～600mm, the pile for prestressed pipe bottom is welded to the resistance to plucking reinforcing bar of few four band crotches, forms the steel concrete enlarged footing.
Screw thread resistance to plucking reinforcing bar is preferably welded in described pile tube bottom.
The light face pile body of described pile for prestressed pipe for adopting template with holes to make.
Described pile for prestressed pipe is for adopting groove face pile body with holes and that the groove face die plate is made.
The pile body external surface of described pile for prestressed pipe has certain thickness tamper, and whole pile body is evenly distributed with drain hole in the pile lining upper edge, and drain hole is communicated with vertical hollow passageway and the husky lining in the pile body.
The utility model adopts applicant's disclosed vibration sinking tube ram machine construction pile for prestressed pipe in ZL2005 20022672.9, do the steel concrete enlarged footing in its bottom, again on pile body the construction a plurality of concrete rings, other two the patent tampers and the drain hole technology that cooperate us again, a traditional light face prestressed concrete pipe pile just becomes the low prestressing force of cost and expands head, resistance to plucking, shockproof and had the pile foundation of improving the foundation soil physico-mechanical properties concurrently.There is the hollow concrete prestressing force or the non-prestressed stake of circle, square, triangle, polygon, multiple light face such as corrugated or groove face in the cross section of this stake.
The utility model proposes the pile foundation that the prestressing force that comes expands head, resistance to plucking, shockproof, double foundation soil processing, construct into the steel concrete enlarged footing in the pile for prestressed pipe bottom, thereby improve the novel pile foundation of its end load and other performance parameter, and have the pile foundation that the physico-mechanical properties of foundation soil is handled concurrently.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Reaching embodiment in conjunction with the accompanying drawings describes.
1, under the situation of former pile for prestressed pipe parameter constant, there is concrete ring 2 at the position that is in gravel layer 3 on the pile body 1 of pile for prestressed pipe, pile body 1 external surface has certain thickness tamper 4, the pile body of pile tube is evenly made drain hole 5 at the whole pile body in pile lining upper edge, and drain hole is communicated with vertical hollow passageway 7 and the husky lining in the pile body.The bottom welding is no less than the indented bars 6 of four band crotches, and length is about 300～500mm.
2, vibration sinking tube pours into and expands a concrete to projected depth; The light face of the band drain hole that will make with the template of light face with holes or groove face or the pile for prestressed pipe pile body of groove face hang in the immersed tube, and vibration pipe-drawing expands head formation naturally.In order to ensure the quality of products, anti-again inserting several times is till pile for prestressed pipe top absolute altitude meets design requirement.Add sand in the tube drawing process and form tamper, add concrete and form concrete ring, and the continuous anti-compacting of inserting, till immersed tube is extracted ground.
