Description
Technical field
The utility model relates to the sheet pile structure in a kind of construction work, is specifically related to a kind of local reinforced fibre reinforced composites (FRP) sheet pile.
Background technology
All the time; what China cofferdam adopted mostly is timber sheet piling, steel sheet pile, reinforced concrete sheet pile, prestressed concrete plate stake and masonry structure etc.; its Steel Sheet Pile has the advantages such as easy construction, intensity is high, modulus of elasticity is large with it; be widely used; but in natural environment for use; especially in marine corrosion environment, be easy to corrosion, steel sheet pile is not in the situation that doing anti-corrosion protection, and its service life is very short.Timber sheet piling is due to its material property, and the very corrosion that is easy to be damaged by worms, has been rarely used in sheet pile cofferdam structure, and concrete sheet-piling, due to from great, is unfavorable for transportation and construction, and operability is poor.
Utility model content
The purpose of this utility model is the problem for existing composite material sheet pile insufficient rigidity, provides that a kind of weight is lighter, rigidity is larger, bearing capacity is larger, cost is lower, the life-span is long, the reinforced FRP sheet pile in the part of easy construction.
The technical solution adopted in the utility model is: a kind of local reinforced fiber-reinforced composite material board stake, and this sheet pile, is interlocked and is formed by connecting between two by the snap close of each FRP pile body side by more piece FRP pile body;
Described FRP pile body is made up of the edge of a wing and web, and the surfaces externally and internally of the described edge of a wing and web is provided with symmetrical projection, and projection inside be solid, hollow or sandwich, forms respectively solid reinforcement, hollow reinforcement or sandwich reinforcement structure.
As preferably, the core of described sandwich is preferably selected carbon fiber plate, can be also flat of timber or steel.
As preferably, described FRP pile body is Z-section FRP pile body or U-shaped cross section FRP pile body.
As preferably, the surfaces externally and internally of the described edge of a wing and web is provided with symmetrical projection, and monolateral projection is 2-3mm, and projection length is not less than 5mm.
As preferably, the surfaces externally and internally of described web is provided with circular protrusion, and circular radius is 2-3mm.
As preferably, size and the projection of described sandwich match.
The utility model is contained in fiber on creel, yarn bundle and the cloth of uncoiling, (or be two-way cloth entirely, do not need yarn bundle) pass through, after a series of guide rollers and boundling screen, yarn collecting wheel, to enter resin-dipping glue groove impregnated with resin simultaneously.Then yarn bundle is by preforming mould, and this mould is the guiding device configuring according to the desired section configuration of goods.
The utility model enters cold mould discharge unnecessary resin and bubble in preformation model after.In cold mould, by water quench, resin viscosity is increased, reduce and run off, finally enter shaping mould, make fiber reinforced material and resin forming and hardening in mould, then pulled out by draw-gear, be cut into the goods of Len req by cutter sweep.
The utility model is suitable for reinforcing and reinstatement works, the waters transformation of seashore and harbour and has more wide application prospect by the engineering infrastructure in Haiti district near a river.
Beneficial effect: it is little that the utility model has solved existing glass fiber compound material rigidity, and the corrosion-prone problem of steel sheet pile, strengthen by the part of sheet pile, and the rigidity of FRP sheet pile is improved greatly.The local flexible design of strengthening of sheet pile, can be designed as solid FRP according to actual operation requirements, also can be designed as hollowly, also can be designed as sandwich.FRP replaces the materials such as steel, has greatly improved the corrosion resistance of sheet pile, and the interface shape of sheet pile is simply various simultaneously, and on-the-spot splicing is rapid and simple, has greatly reduced the engineering time.In the local reinforcing section design of sheet pile, be designed to the rigidity that solid FRP can improve FRP sheet pile, be designed to hollowly can alleviate to a great extent its weight improving in rigidity, reduce cost simultaneously, be designed to sandwich, preferentially select the carbon fiber plate of high strength and modulus, can greatly improve FRP sheet pile rigidity, and do not increase deadweight.If because the restriction of economic condition also can adopt flat of timber or steel as core.Core can synchronously pass through mould with fibre or cloth in pultrusion molding process, and one-body molded, it is convenient to produce, and interface bonding is reliable.
