Abstract

The present invention relates to a method for protecting a bank wall. Stones are filled in a flexible mesh bag to form stone mesh bags, and then a plurality of stone mesh bags are stacked on one side in water of the bank wall or are filled in a levee breach of the bank wall. Each stone mesh bags thrown in the water can be connected. Due to the fact that gaps are formed between stone blocks in the stone mesh bag, the water flow can flow through, but the flow rate is reduced, which decreases the thrust force applied on the stone mesh bag. The stability of the monomer and the whole body of the stone mesh bag are higher, which protects the bank wall. Simultaneously, the mesh bag has flexibility, and therefore, the shape of the whole body can be automatically adjusted in the use course to form excellent wave-proof guard lines.

Description

A kind of method of bank protection

The present invention relates to a kind of bank protection method, particularly a kind of with the bank protection method of the packed rocking of flexible net as anti-ripple carrier.

Protect the seawall at present; administer bunding, the bank protection of hazardous locations such as seashore, river bank, riverbank; generally adopt the T-shaped dam; or on bulkhead wall, settle cement to construct body with special construction; reduce the flow velocity of current, reduce the wash away strength of current, the safety of protection bulkhead wall bulkhead wall; the artificial input ratio of this mode is bigger, and difficulty of construction is also big.Or neatly pile up at bulkhead wall and with cement ditch seam with stone, this structure also can be along with the washing away of current for a long time, and the basis is fallen in and is wholely glided, ftractures or collapse diffusing.When embankment bursts, mostly adopt a large amount of stones in bulk or fill breach with the straw bag filling earthwork, at this moment bursting, inside and outside water-head is big, flow velocity is big, stone or straw bag are subjected to current scour to be easy to cause a large amount of losses, make waste of material, and effect is bad, and dykes and dams are subject to further breaking-up, and are dangerous.

The object of the present invention is to provide a kind of easy construction, good stability, the bank protection method that unfailing performance is high.

The object of the present invention is achieved like this, with flexible net packed rocking, forms stone net bag, then with a plurality of stone net bag estings side in the water of bulkhead wall, or is filled in breach place of bulkhead wall.

The present invention can interconnect the stone net bag that drops in the water.

The present invention can be connected to each other the stone net bag that drops in the water from beginning to end.

Compared with the prior art; the present invention is owing to load stone with mesh bag; form stone net bag, make original stone in bulk be fixed into a bigger integral body, gapped between stone and the stone in the stone net bag; the permission current flow through; the loss of not allowing to be subject to washing away of current and causing stone, the flow velocity that flows through the current of stone net bag is reduced effectively, plays the effect of protection bulkhead wall; and the utilization rate of material is improved greatly.Simultaneously, each stone net bag is coupled together, involve between the gravity of stone net bag and they, can not make floating, the displacement of stone, it is whole to make it to form a good flexible anti ripple protection, can not be shifted or defeated and dispersed, whole stable relative the raising because of washing away of current.

In urgent occasion, because it is gapped between stone in the stone net bag and the stone, current can be by reducing flow velocity, minimizing is to the thrust of stone net bag, do not cause stone net bag by the current washout, the stability of stone net bag monomer is higher relatively, simultaneously, the reduction of flow rate of water flow makes the silt that is mingled with enrich the stone gap, plays the effect of closely knit stone net bag.Like this, use,, can bear washing away of current for a long time, blocked breach effectively, protected the safety of bulkhead wall, have great use meaning because the stability of stone net bag integral body is high in the multiple location of bursting.

In use, be subjected to washing away of current, fall on the basis, and each stone net bag is because of interconnecting one, and mesh bag has shape and the density that flexibility can be regulated integral body automatically simultaneously, forms better anti-ripple guard wire.

The present invention compares with cement, reinforcing bar structure commonly used, more convenient and quicker on making, and cost effectively descends; Characteristics such as in the use, anti-current washout ability is strong, and stability is high, and the life-span is long.

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is the view of mesh bag of the present invention when not closing up;

Fig. 2 is a steel bag of the present invention view when closing up;

Fig. 3 is a stone net bag connection status schematic diagram of the present invention;

Fig. 4 is stone net bag esting of the present invention view a during side in bulkhead wall water;

Fig. 5 is that stone net bag of the present invention is filled the view of bursting;

Fig. 6 is the schematic diagram of stone net bag of the present invention as surf zone protective standard dike;

Fig. 7 is the schematic diagram of stone net bag of the present invention as the T-shaped dam.

With reference to accompanying drawing 1 and Fig. 2, nettle can adopt special knotting mode ecto-entad or shrink from inside to outside and be woven into the plane mesh bag with a certain size, and the profile of plane mesh bag can be circular, square or other geometry.Have two to bring mouth together inside and outside the mesh bag, bring rope 1 respectively together and bring rope 2 closing ins together, the mesh of same mesh bag preferably size is the same, and the different mesh bags of fine meshes greatly can load the stone that varies in size.The nettle of mesh bag can be made of sub-thread, multiply, and mesh bag can be made of individual layer, multilayer nettle.With the practicality is purpose, and the mesh bag that can design different sizes loads the diffusing stone of 1～10 ton of gross weight respectively, is respectively applied for the occasion of different flow rate of water flow.

For reducing stone to the direct impact of nettle and cut damage, can be on mesh bag when placing stone pad last layer straw mattress or other overcoat earlier.The rope 2 that will close up again closes up, and forms stone net bag, and this stone net bag has end to end two and brings mouth together.

The used nettle of mesh bag can be steel wire or stainless steel wire and other strengthens the complex of silk, can coat PVC plastics or other plastic material in the outside of nettle, make mesh bag be flexible, strengthen its in water rotproofness and have certain weight capacity.

With reference to Fig. 3, the connection of stone net bag can adopt the closing in of bringing mouth end to end together of each mesh bag to interconnect by force, thereby single stone net bag is connected into an integral body.

With reference to Fig. 4, the present invention is when implementing, can be earlier in the building stones stockyard the stone mesh bag of packing into, form stone net bag, again stone net bag is transported to the occasion that needs filling, throw or otherwise stone net bag is sent in the water with ship, if not urgent occasion, being pulled the plug by the diver couples together each stone net bag; Perhaps on the water each stone net bag is coupled together earlier, send in the water again.

With reference to Fig. 5, in urgent occasion, because gapped between stone in the mesh bag and the stone, current can reduce the thrust to stone net bag by reducing flow velocity, do not cause stone net bag by the current washout; Simultaneously, the reduction of flow rate of water flow makes the silt that is mingled with enrich the stone gap, plays the effect of closely knit stone net bag.And before rainy season or dangerous situation were arrived, the stone mesh bag of packing into, it was standby as strategic materials to form stone net bag in the building stones stockyard, and dangerous situation can be transported to stone net bag rapidly when taking place needs occasion.

With reference to Fig. 6, stone net bag is dropped in the water, before standard dike 3, form surf zone 4, effectively stop torrent, reduce flow rate of water flow, reduce the impact of current, the safety of having protected standard dike 3 to standard dike 3.

With reference to Fig. 7, this is the vertical view of river levee, at this moment, stone net bag is dropped into formation T-shaped dam 6 in the water by the inboard of embankment 5.Like this, the current of nearly embankment 5 are subjected to the obstruction on T-shaped dam 6, and flow rate of water flow reduces, and the silt that current are carried secretly just forms sediment deposition district 7 in the inboard of embankment 5 precipitation, T-shaped dam 6 also can reduce the impact of current to embankment 5 effectively, and sediment deposition district 7 has also reinforced embankment 5 simultaneously.

Stone net bag of the present invention can drop into the basis that is used as embankment in the water when building embankment, also can be used for building the protective structure of hydraulic engineerings such as bunding bank protection, retaining wall.
