Abstract

The utility model relates to a flexible packaging net sack which belongs to the technical field of engineering materials. The utility model has the technical proposals that the meshes of the net sack are in hexagon shapes, and the diameter of a metal net wire is 0.5 to 3 millimeters. The utility model is a pocket with geometry meshes by the mutual connection of flexible thin steel wires. The utility model has the advantages of good integral stress performance, light weight, small volume, convenient stacking, storage and transportation, low cost, high intensity and corrosion resistance, and the utility model can tightly attach to the formed dam surface at the stacking the dam under the self weight action of stones and can be in mutual conjunction. The utility model has the functions of engineering closure, erosion protection, collapse prevention and the throw, block, and leakage in bank protection, coffer dam and flood proof emergency, and can be used for wave or an antiskid slope, replacing a stilling basin at the front of a water gate, and the purposes are wide.

Description

Flexible packaging net sack

Technical field

The utility model relates to the flexible packaging net sack that a kind of closure, protection against erosion, anti-collapse shore protection, cofferdam and emergency flood fighting that is used for dam construction thrown, blocked up, leaks.Belong to engineering goods and materials technical field.

Background technology

Throw in the closure cofferdam of dam construction and the emergency flood fighting in the prior art, stifled, leak solution commonly used and be: become basket cage or make a basket cage with the reinforcing bar seam, in these baskets cage, fill stone again, they submergeds with iron wire, bamboo strip knitting.Owing to do not see under water, the basket cage that these fall naturally can not neatly be piled up under water.Therefore the basket cage of these regular shape each face between adjacent often direction differ, can not be adjacent to, join the two sections of a bridge, etc, and usually be that a lot of gaps are arranged, mutual related effect is poor, therefore the whole stressed performance of the dykes and dams that form under water is also relatively poor.Basket cage made of iron also easily gets rusty, and is more perishable in water especially.Bamboo basket cage also more yielding falling apart under the washing away of water.Consider from deadweight of basket cage and shared volume, have open defect, particularly the basket cage deadweight of reinforcing bar seam is heavier, for example, adorns the reinforcing bar basket cage of 250 kilograms of stones, conducts oneself with dignity 10 kilograms, accounts for 4% of stone gross weight, and consumptive material is many, the cost height.Simultaneously, the shared volume of these baskets cage is bigger, and the inconvenience transportation is stacked, storage, and this has increased cost virtually again.

Summary of the invention

Characteristics such as the purpose of this utility model is the defective at above-mentioned existence, proposes a kind of flexible packaging net sack, and it has in light weight, and volume is little, and cost is low.

The technical solution of the utility model is that the mesh of mesh bag is hexagon, the diameter 05-3mm of metal twine.

The utility model and the prior art following useful effect of comparing:

When 1, flexible collection dress net was placed stone, no solid shape when piling up dykes and dams, under stone deadweight effect, can be close to the dykes and dams surface that has formed, and agrees with mutually, and holistic resistant behavior is good.

2, in light weight, 0.7 kilogram of the flexibility collection dress net deadweight that carrying stone weight is 250 kilograms only accounts for 1/14 being less than of reinforcing bar basket cage of same bearer ability; Volume is little, and after its horizontal, gauge is very little, and institute takes up space also very little, is convenient to stack storage, transportation.

3, the intensity height is corrosion-resistant.

4, except that be used for engineering closure, protection against erosion, put cave in, shore protection, cofferdam and emergency flood fighting are thrown, stifled, the effect of leaking, also can be used for: the absorption basin when wave, anti-landslide, before replacing sluice, of many uses.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Among the figure 1 is metal twine, the 2nd, and net encloses, the 3rd, net bottom, the 4th, lifting rope.

The specific embodiment

Be a round barrel shape after the expansion of flexible packaging net sack among Fig. 1, it is made up of two parts: net encloses 2 and net bottom 3.Metal twine 1 is that diameter is the stainless steel wire of 1mm, has pliability preferably.Metal twine 1 is that 40mm hexagon mesh is compiled into net and encloses 2 by every length of side.Fig. 2 has showed the establishment figure of net bottom 3, and by how much mesh of several concentric circles and several rectilinear(-al)s of crossing the described round heart, net bottom 3 also is with 1 establishment of metal twine.In net encloses the mesh at 2 tops, penetrate lifting rope 4,, use very convenient so that lift by crane behind the stone of packing into.

Claims

1, flexible packaging net sack is characterized in that the mesh of mesh bag is hexagon, the diameter 0.5-3mm of metal twine.
