Abstract
The utility model describes the bank structure of a kind of plastic-steel sheet pile and Combined concrete, comprise plastic-steel sheet pile, cast-in-place concrete bears down on one or rubble concrete embankment, plastic-steel sheet pile is interconnected by two ends two joint, the sheet pile upper end cast-in-situ concrete connected or rubble concrete, the bottom of sheet pile to be inserted in soil soft clay layer or is inserted below pervious layer.The utility model is easier to soft subsoil process, more effective, can ensure permeable the stablizing of levee foundation and the outer soil layer of land side levee toe, block seepage flow, prevent from emptying, and protects soil, dash and gear soil; Effectively can control the total settlement of levee foundation and levee body and the impact of differential settlement amount.
Description
Technical field
The utility model relates to the bank structure of a kind of plastic-steel sheet pile and Combined concrete.
Background technology
In water conservancy bunds, soft clay, collapsible loess, easily liquefaction expansive soil and diffuse instability process often adopt and excavate or place mat seepy material ballast, beat catch pit, slow down levee slope or adopt the reinforcement means such as vibroflotation method, agitation pile, castinplace pile or employing cement-soil, mortar etc. in soft subsoil.Cost is high, the duration is slow, large to ambient influnence.And when the control of soft subsoil and impervious stream, adopt excavate, soil removal and replacement or vibroflotation method, agitation pile, difficulty of construction is high, and cost is uneconomical.Operation is many, and complicated, and the scope of operation is large, causes certain destruction, and affect greatly by natural climate surrounding ground.
Soft foundation treatment is modal problem in hydraulic engineering, and its bearing capacity is little, and compressibilty is large, and bad hydraulic permeability, easily causes various problem.At soft foundation owing to affecting more by various external factor, as the increase of top loading of constructing, rainfall makes soil body capacity increase, drawdown produces seepage force or reduces due to the shear strength of soft soil foundation own, stability is destroyed, cause unstability built by ground, easily cause accident to occur.
Utility model content
Above-mentioned in water conservancy bunds in order to solve, to the problem run into when soft clay, collapsible loess, easily liquefaction expansive soil and diffuse instability process in soft subsoil, the utility model provides the bank structure of a kind of plastic-steel sheet pile and Combined concrete.
Concrete comprise plastic-steel sheet pile, cast-in-place concrete bears down on one or rubble concrete embankment, plastic-steel sheet pile is interconnected by two ends two joint, the sheet pile upper end cast-in-situ concrete connected or rubble concrete, the bottom of sheet pile is through soft clay layer in soil or insert below pervious layer.
Through pervious layer in soil bottom plastic-steel sheet pile, enter and be greater than more than one meter relative to the degree of depth of impervious layer; Or enter silty clay more than 0.5 meter through Muddy Bottoms clay.
According to the needs in Practical Project, pay the utmost attention to and 100-300mm in cast-in-situ concrete or rubble concrete is stretched in plastic-steel sheet pile upper end; When cast-in-situ concrete is higher to seepage resistance demand, plastic-steel sheet pile upper end stretch into that the degree of depth in cast-in-situ concrete accounts for concrete or the whole height of rubble concrete 2/1 to three/2nds.
Flood control function is had concurrently simultaneously for some view embankments, can cast-in-situ concrete or the indwelling of rubble concrete top fluted, recess width is than plastic-steel sheet pile height many 3-6 mm, and the degree of depth is 150-350 mm, groove, with adding the flood control of plastic-steel sheet pile in the Xin phase temporarily, does not affect view at ordinary times.
Top cast-in-situ concrete or rubble concrete are according to actual conditions and need to change difformity.
Advantage of the present utility model is as follows:
1, for building river, flood-prevention work done on rivers embankment, the generation of piping and current erosion situation can be prevented, and can sedimentation be prevented;
2, in seawall, dyke construction, adopt this structure, can seepage flow be lengthened, increase seepage flow ratio, avoid oozing soil, inrush current phenomenon, protection dykes and dams;
3, adopt this bank structure, a large amount of jackstone construction of tradition can be replaced, greatly shorten the engineering time, save construction cost, and effective current that control destroy trraning pole wash surface;
4, flood season is interim, original embankment can be assembled into combination construction with plastic-steel sheet pile and concrete fast, become temporary flood protection wall, simple and fast;
5, plastic-steel board piling matter is firm durable, stainless, be stale-proof.Stable material quality, contaminated soil and water quality, not lightweight, and construction is easily;
6, guarantee that the osmotic control of levee foundation requires and meets the requirement of static stability, the consolidation process of suitable especially Soft Clay Foundation and pervious levee foundation process, can reduce hand excavation, not affect by landform and depth underground water, and can block up again in order to burst.

Specific embodiment
The bank structure of a kind of plastic-steel sheet pile and Combined concrete, as shown in Figure 9, its middle and lower part plastic-steel board stake penetrates pervious layer in soil, enter the velatively waterproof layer degree of depth 1 meter, top cast-in-situ concrete is trapezoidal, plastic-steel sheet pile upper end to be stretched in cast-in-situ concrete 0.2 meter, also have flood control function concurrently as view embankment simultaneously, indwelling groove in the cast-in-situ concrete of top, dark 0.3 meter of groove, groove width 0.183 meter, add the flood control of plastic-steel sheet pile in the Xin phase temporarily, the plastic-steel sheet pile pull bar added is fixed in the soil on bank, and sand pocket reinforcing can be added at sheet pile both sides heel.
