Abstract
The invention discloses a carbon fiber film precast pile. Carbon fiber sheets or carbon fiber plates are adhered to one side or the whole body of a common precast pile or a precast support pile; and carbon fiber sheets or carbon fiber plates are longitudinally adhered to one side or the whole body of the outer surface of the precast pile or the precast support pile. The carbon fiber film precast pile provided by the invention is reasonable in structure and convenient to use, flexural stiffness of the support pile and anti-deforming capability of an envelope structure of a foundation pit can be improved greatly, and cross section types of the precast pile and adhesion modes of carbon fiber films can be flexibly selected according to requirements of load-carrying properties of the envelope structure of the foundation pit.
Description
Technical field
The present invention relates to the support pile of a kind of base pit engineering, particularly relate to a kind of carbon-fiber film prefabricated pile。
Background technology
In foundation ditch suspended wall retaining design, prefabricated pile is because its speed of application is fast, construction technology is simple, cost is low, horizontal layout is flexible, the advantages such as environmental effect is little are increasingly being application。But it is compared with non-driving into type campshed, except having soil compaction effect, the support system that also arrives because bending rigidity is less deformation is excessive, have impact on the further application in foundation pit system of this pile-type。Carbon fiber has advantage corrosion-resistant, ageing-resistant, fatigue proof, has been widely used in the structural strengthening reinforcement of the infrastructure bending resistances such as work China Democratic National Construction Association, bridge, water conservancy, member in shear memory。The tensile strength (7-10 times for steel) that carbon fiber is remarkable, it is pasted on the tensile region of bending resistance component (beam, support pile), the bending rigidity of bending resistance component (beam, support pile) can be greatly enhanced, substantially reduce the amount of deflection of bending resistance component (beam, support pile)。The present invention relates to a kind of carbon-fiber film prefabricated pile。
Summary of the invention
The technical problem to be solved is to provide one and meets foundation pit enclosure structure load-carrying properties requirement, rational in infrastructure, easy to use, and the more conventional prefabricated pile of load-carrying properties is high, the compound carbon-fiber film prefabricated pile that the more conventional prefabricated pile of overall cost is low。
The present invention solves that above-mentioned technical problem employed technical scheme comprise that a kind of carbon-fiber film prefabricated pile of offer, wherein, at the side of prefabricated pile or prefabricated support pile or paste List carbon-fiber film。
Above-mentioned carbon-fiber film prefabricated pile, wherein: carbon-fiber film is carbon cloth or carbon fiber board。
Above-mentioned carbon-fiber film prefabricated pile, wherein: prefabricated pile cross section type be round, square, circular ring type, square-outside and round-inside shape type, template, template with ribbing, H type, square end T-shaped, double-T shaped, middle round in one。Wherein, can increasing dividing plate in the middle of the prefabricated pile of circular ring type or middle square end circular arc type, dividing plate is I-shaped, or cross formula, or screen work formula。
The present invention has the advantages that relative to prior art
Rational in infrastructure, easy to use, the bending rigidity of support pile and the non-deformability of foundation pit enclosure structure can be increased substantially, and can require to select flexibly the bonding method of the cross section type of prefabricated pile, carbon-fiber film according to the load-carrying properties of foundation pit enclosure structure。
