Abstract
The utility model relates to a polyamide fiber cast-in-place concrete flexible anti-scour raft. The flexible anti-scour raft comprises cast-in-place concrete block body, a polyamide-fiber rope and an erection reinforcement mat, wherein the polyamide-fiber rope is connected with the cast-in-place concrete block body in series vertically and horizontally, the polyamide-fiber rope is positioned in the middle of the cast-in-place concrete block body and is colligated with the nodes of the erection reinforcement mat into the mesh shape, the cast-in-place concrete block is divided into a pre-pouring block body and a post-pouring block body which are arrayed at intervals vertically and horizontally, a dilatation joint is arranged between the two adjacent cast-in-place concrete block bodies and is filled with polyphenyl foam, the polyamide-fiber rope is long enough to stretch into the dilatation joint, and the optimum width of the dilatation joint is 5cm, and the reserve length of the polyamide-fiber rope in the dilatation joint is 10 to 20cm. The flexible anti-scour raft has the beneficial effects that the cast-in-place concrete block body can effectively prevent scour and protect the river bed at bottom or a stone riprap, the concrete block bodies are connected by the polyamide-fiber rope with high intensity and corrosion resistance, therefore, the flexible anti-scour raft can be effectively suitable for the foundation deformation, meanwhile, the flexible anti-scour raft has the advantages of simple structure, convenient construction and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of water conservancy erosion control body, dashes row in particular for the polyamide fibre cast-in-situ concrete flexible anti of protection power station (power plant), outlet structure escape works upstream and downstream riverbed and dike prevention slope and levee toe.
Background technology
At present, water conservancy erosion control body is divided into flexible and rigidity two classes.It is poor that rigidity erosion control body such as concret block, placed rockfill etc. exist to adapt to deformability, and it is broken and broken up defective such as washout one by one by current that whole fracture takes place easily; Flexible anti is towards body such as galvanized wire cage, alloy steel mesh stone pocket or net cage etc., and they can well adapt to foundation deformation, can not weaken overall structure.When deformed by the current scour, flexible anti is followed sinking towards physical efficiency, still keeps original framework and reaches new balance, destroys thereby protection protection main body exempts from current scour.It is higher relatively and easily adhere to rubbish towards the body cost that galvanized wire cage, alloy steel mesh stone pocket or net cage etc. are similar to such flexible anti, is unfavorable for view and environmental requirement.Also has a kind of flexible anti in the hydraulic engineering towards body; main sectional type porous compoboard by the wire lath build-in; general thickness is thinner; be mainly used in dike prevention slope; if be used to protect the riverbed that washed away by high-velocity flow certainly will need to increase compoboard thickness and wire diameter reaching the erosion control purpose, but can increase construction costs like this.Though the square hole on the compoboard plate can be used for draining and plantation plant on bank protection, if be applied in the protection engineering in riverbed, the sandy soil fine grained is easily taken away by current, is unfavorable for the protection in riverbed.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, thus provide that a kind of cost is low, outward appearance neatly, can not attached water in the polyamide fibre cast-in-situ concrete flexible anti of rubbish compliance with environmental protection requirements dash row.
The technical solution adopted in the utility model is: it comprises cast-in-situ concrete block, caprone cable, handling reinforcement net, caprone cable is two-way series cast-in-situ concrete block in length and breadth, and caprone cable is positioned in the middle of the cast-in-situ concrete block and is netted with the node colligation of handling reinforcement net.
Described cast-in-situ concrete block be divided into water earlier block with after water block, water earlier block with after water block and be two-way in length and breadth and be spaced.
Described cast-in-situ concrete block whenever is provided with the shrinkage joint between adjacent two, fills polyphenyl foam in the shrinkage joint, and described caprone cable is reserved sufficient length in the shrinkage joint.
Described shrinkage joint width is 5cm, and the caprone cable length of reserving in the shrinkage joint is 10～20cm.
The beneficial effects of the utility model are: the cast-in-situ concrete block is erosion control effectively, and protection riverbed, bottom or stone riprap utilize the caprone cable of high-strength corrosion-resisting to connect between each concret block; can effectively adapt to foundation deformation; and simple in structure, easy construction, cheap.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is cast-in-place block of handling reinforcement of monolithic of the present utility model and caprone cable connection layout.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: the utility model polyamide fibre cast-in-situ concrete flexible anti is dashed row, comprise cast-in-situ concrete block 1, caprone cable 2, handling reinforcement net 3, caprone cable 2 is two-way series cast-in-situ concrete block 1 in length and breadth, and caprone cable 2 is arranged in cast-in-situ concrete block 1 and is connected with the node colligation of handling reinforcement net 3 and is netted.Described cast-in-situ concrete block 1 be divided into water earlier block 1a with after water block 1b, water earlier block 1a with after water block 1b and jump piece and build two-way in length and breadth being spaced.Cast-in-situ concrete block 1 whenever is provided with the wide shrinkage joint of 5cm 4 between adjacent two, fills polyphenyl foam 5 or other flexible materials in the shrinkage joint 4, and the length of the caprone cables of reserving in the shrinkage joint 42 is 10～20cm.
In Fig. 1 and Fig. 2, cast-in-situ concrete water earlier block 1a, after water block 1b and twist with the fingers caprone cable 2 by φ 16mm three glue and connect, jump piece and build, between establish 5cm shrinkage joint 4, in fill out polyphenyl foam 5, reserve the long 10cm～20cm of rope in the seam.
In Fig. 3, middle part in cast-in-situ concrete block 1, φ 16mm three glue are twisted with the fingers caprone cable 2 and are connected with each node colligation of handling reinforcement net 3.
