Abstract

The utility model provides a thread connecting precast block soft row, including a precast block, wherein an orthogonal through hole is arranged along the length and the width direction, and a plurality of precast blocks constitute the precast block soft row in series and in parallel by the ropes. A loom is disposed at the lower part of the precast block soft row, and the rope and the loom are connected together. Two through holes are arranged in the precast block staggering at the short transverse not on the same plane and a groove is arranged at the outlet part of the through hole along the short transverse. Four edges on the upper part or the lower part of the precast block are edge roundings, occupying 1/3-1/2 precast block height. Two orthogonal through holes are arranged in the precast block located at the central extra thin noodle of the length and the width. The utility model is monolithic stable, avoiding the shift of the individual block or the superposition and leak caused by the lift. The four edges of the precast block are round chamfers, and the coupling gap between the blocks can be made small enough, providing enough protection to the mat; meanwhile, has softness to adapt the river bed deformation to a definite extent.

Description

Wire rope handling connects the prefabricated section soft raft

Technical field

The utility model relates to a kind of wire rope handling and connects the prefabricated section soft raft, belongs to the civil works field, is used for the soft raft that is connected into by prefabricated section of river, river, lake, extra large bank protection, Hu Tan, river bottom protection.

Background technology

A lot of rivers mostly are sandy riverbed, and short texture is easy to be washed away, and river course, the middle and lower reach of Yangtze River is exactly like this.Stable for the safety that guarantees regulating structure and beach body, riverbed, China is in the waterway regulation works that carry out the middle and lower reach of Yangtze River at present, and river bottom protection and shoal protection works occupy suitable proportion.

The soft raft that protects beach, river bottom protection employing at present comprises row's pad and ballast carrier two large divisions, and wherein row fills up at current and movably plays buffer action between the riverbed, to stop bed scour.Ballast carrier mainly plays stable row's body and protection row pad is avoided destroying.The ballast mode comprises diffusing throwing and is to connect two kinds.The throwing ballast globality of loosing is not strong.System connects ballast and often has certain slit, needs other packing material, has not only increased cost, and under big flow conditions the easy washout of packing material, thereby influence row body is protected the anti-aging stable condition of husky erosion control effect and row's body.

Summary of the invention

The purpose of this utility model provides a kind of wire rope handling and connects the prefabricated section soft raft, is used for row's pad ballast, or directly plays river bottom protection and protect the beach effect.

The technical solution of the utility model: wire rope handling of the present utility model connects the prefabricated section soft raft, comprises prefabricated section, in prefabricated section, has mutually perpendicular through hole along length and width, and a plurality of prefabricated sections constitute the prefabricated section soft raft with the rope connection in series-parallel.

Below the described wire rope handling connection prefabricated section soft raft, prefabricated section soft raft is woven cloth, and rope is connected with woven cloth.

Described wire rope handling connects the prefabricated section soft raft, and two through holes stagger up and down in short transverse in the prefabricated section, and not on a horizontal plane, four top or following ribs of prefabricated section are chamferings.

Described prefabricated section soft raft, there is the groove along short transverse four sides of prefabricated section in the through hole exit.

Described wire rope handling connects the prefabricated section soft raft, and the chamfering of four top or following ribs of prefabricated section is an arc angling, accounts for 1/3-1/2 prefabricated section height, faces staggered up and down the putting of chamfering of two prefabricated sections during the clamp dog soft raft mutually.

Described wire rope handling connects the prefabricated section soft raft, and mutually perpendicular two through holes are arranged in the prefabricated section, and two through holes are positioned on the long and wide center line face.

Advantage of the present utility model: compared with the prior art, the company's of wearing mode of prefabricated section makes the ballast block constitute monolithic stability, avoids the generation displacement of single block or lift being directed at overlapping, crack.Four ribs of prefabricated section are rounded corners, and the connection slit of piece and piece can be accomplished enough little, can provide sufficient protection to row's pad; Certain flexibility is arranged simultaneously, can adapt to river-bed deformation to a certain degree; Have characteristics such as easy construction, efficient height, cost be low simultaneously.

The specific embodiment

In small-sized prefabricated section, reserve the design perforation, pass perforation, prefabricated section is tied in length and breadth, make single prefabricated section become the integral body row body of certain scale by designing requirement by rope or other streak flexible materials.Below in conjunction with accompanying drawing the utility model specific embodiment is described.

Fig. 5: be that the utility model wire rope handling connects prefabricated section soft raft general structure schematic diagram, Fig. 4 is the side-looking structural representation of prefabricated section with rope connection and mutual chamfering position: this soft raft can play the beach river bottom protection effect of protecting as soft raft separately.The utility model with prefabricated section 1 by mutually perpendicular two through holes with rope 7 connection in series-parallel, face mutually that the chamfering of two prefabricated sections is staggered up and down puts (as Fig. 4), a plurality of prefabricated sections string into a continuous prefabricated section soft raft protective surface with rope.

Second kind of embodiment of the present utility model such as Fig. 6: under the prefabricated section soft raft of Fig. 5, increase woven cloth (adopting the polypropylene filament yarn braiding) 8.With prefabricated section 1 by mutually perpendicular two through holes with rope 7 connection in series-parallel, staggered up and down put (as the Fig. 4) of chamfering that faces two prefabricated sections mutually, a plurality of prefabricated sections string between a continuous prefabricated section soft raft prefabricated section soft raft and woven cloth rope and the woven cloth and can simply stack with rope, also can be connected to form an integral body by modes such as knottings, 7-1 is a johning knot.

The prefabricated section soft raft is layered on riverbed, sea bed, the dike surface, beach, and can prevent has big drift between prefabricated section.During beach dike areal deformation, because prefabricated section has chamfering, prefabricated section soft raft protective surface can change thereupon, make prefabricated section can not squeeze folded, arch upward.

Fig. 1 is a prefabricated section structural representation of the present utility model, Fig. 2: be prefabricated section side-looking structural representation of the present utility model, Fig. 3: the horizontal sectional structure schematic diagram of A-A that is Fig. 2: prefabricated section is for having length, wide, high square hexahedron prefabricated section, in prefabricated section 1 height, have mutually perpendicular two through holes 2 and 3 along length and width, two through holes stagger up and down in short transverse, not on a horizontal plane, the size of through hole is that the thickness according to the size of prefabricated section and used rope determines, the through hole exit has along the groove 5 of short transverse and makes things convenient for the wire rope handling rope.Four top or following ribs of prefabricated section are rounded corners 4, and rounded corner is the 1/3-1/2 height.The size of prefabricated section can change according to actual needs.
