Abstract
The technology of fiber reinforced concrete pile composite foundation is characterized in that after hole is formed, 0.5-2.0 Kg/m3 fiber or broken fiber fabric is manually or mechanically blended with CFG pile material or cement to form reinforced mixed material which is tampered or poured to form pile, the pile body has no steel bar. The fiber reinforced pile is raised in bending strength, shear strength, tensile strength and crack resistance, so that it raises the horizontal and vertical bearing strength of composite foundation. The expense of foundation treatment is 50-70% of common pile foundation.
Description
The present invention relates to a kind of foundation basic construction technology.
Existing two kinds of composite foundation treatment technology: CFG (cement, flyash, rubble) pile composite foundation technology and tamped Cement-soil Pile Composite Foundation Technology are used widely in many multistory buildings and middle-high building ground, and economic benefit is very remarkable.But because the equal configuration reinforcement not of pile body, the anti-horizontal loading of its foundation pile, on dial load, the impact load ability is low.
The purpose of this invention is to provide a kind of fiber and steel bar reinforced concrete pile composite foundation technology, strengthen level, the vertical bearing capacity of CFG stake and rammed concrete pile, and foundation pile shearing resistance, bending resistance, cracking resistance, resistance to tension, widen range of application, further reduce ground and handle cost.
Construction sequence of the present invention is:
(1). with artificial or mechanical hole building;
(2). fiber or debris fabric are become the reinforcement mixed material by artificial or machinery with CFG stake compound or cement-soil compound mix;
(3). with the reinforcement mixed material, through artificial, mechanical compacting or perfusion pile, pile body is unworthy of reinforcing bar, does foundation pile total length section or section perfusion of stake top;
(4). make bed course with sandstone.
Described fiber or debris fabric can be that selection is a kind of in the following kind: Fypro, polyester fiber, polypropylene fibre, polyethylene fibre, polyvinyl chloride fibre, glass fiber, steel fibre.
The addition content of described fiber is 0.5～2.0 kilogram/cubic metre.
Advantage of the present invention: the stake behind fiber or debris fabric reinforcement, strengthened pile body self bending resistance, cut, draw, split equal strength and anti-crushing, wear-resistant and impact resistance, thereby improve the Its ultimate bearing capacity and the vertical bearing capacity of composite foundation, CFG pile capacity standard value reaches 450～500KPa, and the rammed concrete pile standard value of bearing capacity reaches 250～300KPa; Pile body need not be joined reinforcing bar, saves just steel, and it is about 50%～70% of general pile foundation that ground is handled comprehensive cost, is applicable to the above shallow layer foundation reinforcing of groundwater table.
Below in conjunction with embodiment the present invention is described in detail:
First embodiment: earlier with artificial or mechanical hole building; Again fiber or debris fabric are become the reinforcement mixed material by artificial or machinery with CFG stake compound or cement-soil compound mix; With the reinforcement mixed material, through artificial, mechanical compacting or perfusion pile, pile body is unworthy of reinforcing bar, does foundation pile total length section or section perfusion of stake top; Make bed course with sandstone at last, thickness is the 100-300 millimeter.The addition content of fiber is 0.9 kilogram/cubic metre.
Embodiment two: the addition content of fiber is 1.0 kilograms/cubic metre.
Embodiment three: the addition content of fiber is 1.1 kilograms/cubic metre.
Embodiment four: the addition content of fiber is 1.2 kilograms/cubic metre.
Claims (3)
