Description
Technical field
The utility model relates to a kind of U-shaped prefabricated sheet pile, and more specifically, it relates to the hollow U-shaped prefabricated sheet pile of a kind of variable cross section-type.
Background technology
Sheet pile, the one of fender pile, is generally used for bracing of foundation pit, bank protection work, erosion and torrent control works, water conservancy project and harbor work's engineering etc.Existing sheet pile can be divided into three kinds of timber sheet piling, steel sheet pile and reinforced concrete sheet piles by material.Timber sheet piling intensity is low, easily corruption, and lumber consumption is large, general only for Temporary Cofferdam engineering, steel sheet pile material is light, steady quality, watertightness is good and the construction period is short, but difficulty of processing causes greatly construction costs too high, and exist the engineering of cast-in-place structural to be difficult to recycle for top, and need take effective rust preventing.Reinforced concrete sheet pile good endurance, adopts prefabricated or cast-in-place construction plan is reasonable, can not delay the entirety duration, and construction costs is much lower compared with steel sheet pile, in shore protection and the extensive use of sheet-pile wharf engineering.
At present, conventional reinforced concrete sheet pile mainly contains rectangle sheet pile and U-shaped sheet pile two classes.Wherein rectangle sheet pile precasting process is easy, easily stack, transportation, but in engineering application bending resistance deficiency; U-shaped sheet pile is the opposite sex stake being developed by rectangle sheet pile, not only has better bending resistance and disappears wave effect obviously than ordinary rectangular sheet pile, and the soil that also can save navigation channel utilizes area, has better practical application effect.But traditional U-shaped reinforced concrete sheet pile exists concrete consumption large, when piling construction, connect wing plate and be easily caught broken by machinery, and with the problem such as top cast-in-place structural bonding strength is low.
In sum, although existing reinforced concrete sheet pile is compared the existing plurality of advantages of other sheet pile structures, and the U-shaped reinforced concrete sheet pile of optimizing is thus had outstanding performance in anti-bending strength, land utilization ratio, but still exist consumptive material large, construction quality is difficult to guarantee, with the low deficiency that waits of superstructure bonding strength.Given this, need at present that invention a kind ofly can meet that anti-bending strength is strong simultaneously badly, concrete consumption less, bonding strength is large, construction safety is reliable, the hollow U-shaped prefabricated sheet pile of variable cross section-type of the multipurpose such as good in economic efficiency.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides one to have better load-carrying properties, integrated connection intensity, has again the hollow U-shaped prefabricated sheet pile of variable cross section-type that pile sinking is easy, cost is low, technical economic benefit is good simultaneously.
The hollow U-shaped prefabricated sheet pile of this variable cross section-type, comprises hollow Integral U-shaped panel and solid separate type rectangular panel; U-shaped panel is positioned at prefabricated sheet pile top, and U-shaped panel top is run through wooden partition level connection joint reinforcing bar is evenly set, and two connect wing plate side arranges respectively the concavo-convex tongue and groove of half elliptic, and concavo-convex tongue and groove rear portion is symmetrical arranged steel panel, and below steel panel, gutter is set; Separate type rectangular panel is positioned at prefabricated sheet pile bottom, and stake end arranges inverted trapezoidal stake end cutting edge.
As preferably: described Integral U-shaped panel only arranges groove in the top board of prefabricated sheet pile and biside plate, and groove interconnects and is U-shaped, groove width be U-shaped panel plate wide 1/2～2/3.
As preferably: described level connection joint reinforcing bar is only embedded in top board and the biside plate top of precast plate stake in advance, and runs through groove.
As preferably: the spill tongue and groove inwall of described connection wing plate arranges rubber water-proof bar, and rubber water-proof bar and tongue and groove are isometric.
As preferably: described separate type rectangular panel is only distributed on the top board and biside plate of prefabricated sheet pile, connect as one with Integral U-shaped panel, and both thickness equate.
The beneficial effects of the utility model are: (1) U-shaped sheet pile adopts hollow variable cross section-type, guaranteeing, under the prerequisite of stress performance, can significantly to reduce concrete use amount, reduce project total cost.(2) setting of steel panel can effectively prevent that U-shaped sheet pile wing plate top is caught broken by construction machinery in pile driving process, at sheet pile top, level connection joint reinforcing bar is set simultaneously, do not affecting under the prerequisite of hanging stake, can effectively strengthen the switching performance of sheet pile and superstructure, improving the globality of bank protection structure.(3) setting of gutter can be discharged the underground water in land side soil layer in time, reduces the lateral earth pressure of sheet pile, improves the resistance to overturning of structure.
