Concrete bears down on one, and can be prefabricated into top be a transverse slat, and bottom is two risers perpendicular to transverse slat, the thick 40-80mm of top transverse slat, and riser is thick is 30-50 mm.Preferred a kind of scheme is beared down on one by concrete to be prefabricated into approximate " ∏ " shape, gap ratio plastic-steel sheet pile height many 2-6 mm inside two risers, riser is long is 150-250 mm, the above 50mm place of riser lower edge, avoids connector position, reserved diameter 12mm fixing hole, at sheet pile correspondence position also respective perforations, pass with stainless steel screw rod, fix with screw, nut, intermediate sleeve galvanized pipe; Another preferred version is that prefabricated concrete bears down on one in the middle of bottom two riser and forms the consistent groove of sheet pile upper end shape along sheet pile closure, and such as select the stake of M template, then the shape of groove is M type; The width 2-6mm more than sheet pile thickness of groove, at the connector position well width of two sheet piles than sheet pile thickness many 4-8 mm, riser is long is 50-80 mm.M10 pointing with cement mortar in junction between concrete bears down on one.
The model of sheet pile can select M type or other suitable models, then the concrete preformed shape that concrete bears down on one also mates with sheet pile accordingly, and sheet pile is connected with T junction by the groove at two ends.
The concrete strength that precast concrete bears down on one is more than C60.
A kind of plastic-steel sheet pile that the utility model relates to and the bank protection structure of Combined concrete have following outstanding advantages:
1, can be used for river or lake shore protection, this combining structure is safe, stable, and speed of application is fast, and cost is low, environment friendly and pollution-free, little to surrounding environment influence, and durability is long, without the need to later maintenance;
2, soil erosion in river, river levee bank can be prevented from source, reduce bed-silt; And can be used for impervious stream, seepage flow ratio can be increased, prevent embankment generation seepage flow from causing piping, protection dykes and dams, solve levee body antiseepage problem, meet the requirement of analysis of seepage flow stability;
3, river, river ecological disruption can be reduced, meet surrounding enviroment and view requirement, have firm durable, antiscour, the advantage that abrasion resistance is strong;
4, anti-wave impact is made good use of.
