Description

A kind of compound sea wall

Technical field

The utility model relates to a kind of sea wall, particularly a kind of compound sea wall.

Background technology

Along with deepening continuously of China's reform and opening-up, China's economic construction stable and rapid development, especially economy development of coastal area has obtained remarkable achievement.As everyone knows, land resources is the important foundation that guarantees economic development, is accompanied by rapid economy development, and the construction land growing tension is coated with to the seabeach and wants the soil, has become the common recognition of coastal economy developed regions.The bracing of foundation pit of building construction and ground are handled quantity also sharply to be increased; Require also increasingly highly, but be coated with the enrockment embankment method of making in the ground engineering, need a large amount of exploitations and use building stones enclosing in the past; Surrounding enviroment are caused adverse influence, and big because of the embankment structure section, waste a large amount of soils.Adopting bored pile as main bending resistance component and adopt common enhancing body to form composite foundation; Bored pile produces a large amount of mud in long-term construction; Traditional technology has shortcomings such as environment pollution is big, long construction period, construction costs height; Therefore people inquire into various one-tenth dike methods constantly, have proposed multiple compound Haiti.

Chinese patent notification number CN200985497Y discloses a kind of dykes and dams, comprises sand cushion, the orlop that it is covered in the face of land under water and is positioned at said dykes and dams; Plastic draining board is therebetween at a distance from also vertical said sand cushion setting; Be followed successively by hardcore bed, geotechnological layer of cloth, dike heart body, piece stone bed course, barrier board, block stone layer and the barrier board common external surface that forms the dykes and dams both sides in surface of piece stone bed course one side dorsad; The upper surface of dike heart body is breastwork pad and breastwork.This dykes and dams only rely on plastic draining board and the various layer that rockfills to construct, and the basis is insecure, and floor space is big, and bearing capacity is low.

Chinese patent notification number CN1296565C discloses frame type combination dykes and dams.A kind of be used for water conservancy, maritime engineering in the riverbed dykes and dams with the estuary improvement that goes to sea.It contains groove stake, mask precast plate, tensile tie-beam, and wherein the groove stake is arranged to be no less than two rows, and the groove stake is provided with notch, and the thickness of mask precast plate and the shape of notch and size are complementary, mask precast plate piecemeal successively intercalation to adjacent two with in the emissions groove stake; The two ends of tensile tie-beam connect with two adjacent different-row groove piles respectively.The bottom of groove stake is preferably wedge shape.The bottom of the sole piece of mask precast plate is preferably wedge shape.The transverse shape of mask precast plate can be several fonts, also can be rectangle and T font.This combination dykes and dams consist of the groove stake, cost is high, bearing capacity is limited, tensile tie-beam is the intercalation structure, firmness is not enough, dykes and dams still can not bearing pressure.

Chinese patent publication number CN1514068A relates to a kind of dam configuration body and job practices thereof.Described dam configuration body comprises stake, crossbeam, dividing plate; Described dam configuration body is branch row, and each arranges the described stake that distributes, the front-seat stake and an interlaced layout of adjacent rows, and the stake of face is first campshed near water, away from first campshed is last campshed; Connect structure triangular in shape between the described adjacent studs through described crossbeam; Be provided with described dividing plate between described first campshed, described dividing plate is not less than bank soil; According to the structure construction of described dam configuration body, cast stake successively, crossbeam, dividing plate.This dykes and dams openly the earliest, cast-in-place crossbeam is rigidly connected each pile body, is a kind of very outstanding dykes and dams, but still existences needs the difficult problem of construction at sea, while dykes and dams primary filling earthwork is big, causes sedimentation easily, dam body can't bearing pressure.

Summary of the invention

The purpose of the utility model be to solve the dykes and dams floor space that exists in the background technology big, can not construct on land, dykes and dams can't bearing pressure etc. problem, provide a kind of bearing capacity the big compound sea wall that can be used as the road surface.

To achieve these goals; The technical scheme of the utility model is: a kind of compound sea wall, comprise basic dregs layer, and equally distributed major diameter has the stake of muscle tube in the basic dregs layer; Lay secondary dregs layer on the dregs layer of basis; Both sides are provided with reinforced concrete member respectively as retaining wall on the secondary dregs layer, and the retaining wall of both sides is connected by steel strand respectively, retaining wall inner with the road surface to the absolute altitude formation dike of banketing, top.

The composite foundation that this sea wall is made up of dregs and tube stake, setting is made up of the soil subgrade of reinforced concrete member clamping on composite foundation; Because steel and concrete structure spare pseudoconjugant good stability, volume is big, and quality is heavy, and composite foundation is carried out suppression, and the big sedimentation of steel and concrete structure spare bottom area is little, has improved the anti-shear ability of composite foundation simultaneously; And the side strong shock resistance of reinforced concrete member, so the ability of sea wall storm resisting is big; Owing to adopt prefabricated component, make the integral width of sea wall reduce, reduced the earthwork of sea wall, difficulty of construction is little low with construction cost, becomes dike quick.

As preferably, the both sides of the reinforced concrete member of said retaining wall on secondary dregs layer in pairs or be crisscross arranged, each reinforced concrete member is connected by the reinforced concrete member on steel strand and opposite.Make that so whole dykes and dams are a pseudoconjugant, the stability of dykes and dams is stronger.

As preferably, the small diameter long stake is crisscross arranged on the said secondary dregs layer.It is poor that the sea wall of this structure is applied to environment, and stressed complicacy or the big occasion of sea wall road surface bearing capacity are on the basis of the short tube stake of major diameter; Squeeze into the small diameter long stake with short tube stake dislocation; Get to bearing stratum always, formed the composite foundation of being made up of jointly the stake of height thickness, the basis is firmer.

As preferably, on the said secondary dregs layer continuous impervious wall is set.This structure is mainly used in the demanding sea wall of permeability rate, uses continuous impervious wall, can improve the water resistance in the dike.Impervious wall is in the outside of retaining wall or in the centre of two retaining walls.Where specifically be arranged on, still select to confirm according to dike location environment and instructions for use.

As preferably, the reinforced concrete member of said retaining wall is caisset or counterfort structure or suspended wall structure.The prefabricated component of these 3 kinds of structures is often to use when building sea wall, and its floor space is big, highly can design according to demand, and is in light weight, is fit to very much the utility model and is used for tractive making retaining wall.

The utility model provides a kind of sea wall that meets, and has tangible advantage: since only construction in the land, easy construction; Adopt prefabricated reinforced concrete member retaining wall above the composite foundation, floor space is little, becomes dike speed fast; The sea wall Stability Analysis of Structures, capacity of anti-storm is strong; The dike face can be used as road and kills two birds with one stone.
