Description
Technical field
The utility model belongs to dredge before dredge rear field of engineering technology, more particularly to one kind for high wind wave profundal zone improve
Soft raft and grid process stability structure.
Background technology
At this stage, China geotechnique textile industry has begun to take shape, but compared with the advanced countries such as America and Europe and area, industry
The horizontal and mating Standard System Construction of overall technology etc. still in the relatively low stage.
Earth work fabric soft revetment has the characteristics that anti-filter, isolation, erosion control and globality, adaptable, is widely used to
The various aspects of waterwork, it can be effectively prevented flow and directly wash away river (sea) bottom and cause river because of flow osmosis
The local deformation of (sea) bed destroys, and overcomes many problems present in traditional defense structure, with the development of economy, coastal edge
The waterwork in river also gradually develops to deep water, remote bank direction, the soft raft laying process of profundal zone also and then to " deep, danger,
Hardly possible " direction extends, is progressive.However there is no effective finished product protection measures after placement at this stage, in high wind wave profundal zone
Soft raft often has the following problems in arranging：
1, since live stormy waves takes place frequently and larger, the intensity of isostere is often unsatisfactory for site requirement, easily causes tearing, breaks
It is bad.
2, construction site flow is larger, and soft raft edge silt easily starts, and causes not protect the gradual incision of sea bed, with flow
The lengthening of action time, soft raft edge do not protect sea bed substantially incision, form local scour hole, promote the deformation of soft raft broken
It is bad.
3, it is limited by processing technology, row, which pads, mostly uses longitudinal reinforcement, and laterally non-reinforcement so that isostere flexibility is not enough to fit
Riverbed is answered to deform by a relatively large margin, after isostere " suspension ", the pulling force in isostere is torn when being more than tensile strength.
4, it being limited by processing, isostere width is smaller, when scour hole is developed to two pieces or more isosteres by shield region, lap-joint
The easy exposure in riverbed so that wash away easily to soft raft in-house development.

For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing：
It please refers to Fig.1 and Fig. 2, one kind improving soft raft and grid process stability structure for high wind wave profundal zone,
It is characterized in that：TGXG 1 including full paving and composite earthwork soft raft 2 are equipped with compound at the lower section both ends of TGXG
Geotechnological soft raft, the composite earthwork soft raft include anti-aging buffer layer 3 and geotextiles 4, and the anti-aging buffer layer is located at
Between TGXG and geotextiles；Vertical dike axis direction, which is spread, in the upper surface of TGXG is equipped with full sand ribbed soft mattress, it is described complete
Sand ribbed soft mattress, the both sides of the edge sand rib 5 that ballast density is 1/0.5m within the scope of 4m of composite earthwork soft raft, soft raft
Other positions ballast density be 1/2m sand rib, TGXG top ballast density be 1/2.5m sand rib.
The utility model can also use following technical measures：
The both ends of the TGXG are equipped with draw ring 6.
The TGXG is equipped with reinforcing rib, and the density of reinforcement is 1/m.
The invention further relates to a kind of constructions improving soft raft and grid process stability structure for high wind wave profundal zone
Method：Include the following steps：
1) TGXG is selected first, and determines form of mating formation：Field working conditions are understood, construction area sheltering condition
Poor, stormy waves and trend are larger, in the majority with deep water underwater construction due to constructing, once encountering strong wind bad weather, are made to finished product
At being affected, the high-strength TGXG of material selection is determined in such execution conditions, and use the form of mating formation completely spread, and right
TGXG is equipped with reinforcement, and the density of reinforcement is 1/m, and both sides are equipped with draw ring, using the good globality of earth working material,
Levee body basis forms reinforcement cushion, and both sides are compound with geotextiles, it is ensured that the good integrity of soft raft, isostere self-strength are high.
2) secondly, anti-aging buffer layer is added in both sides, and TGXG, anti-aging buffer layer are formed at the both ends of TGXG
The compound anti-aging buffer layer constituted with geotextiles；Isostere self-strength can be improved using three-layer composite structure, and be unlikely to
It is overweight, it is light and soft.
3) third determines the design parameter of associated materials according to the relevant parameter that the actual conditions at scene, design provide；
TGXG is using the warp knit polyester filament two-way stretching grating for setting corrosion-inhibiting coating：
| Serial number | Project | Unit | Technical indicator |

Geotextiles are using the short fine non-woven fabrics of anti-aging polypropylene：
Shock resistance anti-aging intermediate buffering protective layer technical indicator：
4) finally, using full sand rib ballast, i.e., in the both sides of the edge of composite earthwork soft raft within the scope of 4m ballast density
Other positions ballast density for 1/0.5m, soft raft is 1/2m, and TGXG top ballast density is 1/2.5m.Entirely
Sand rib ballast, ballast mode is light simple, and swift to operate, labor intensity when reducing construction operation accelerates speed of application.And
Isostere adaptability to changes is preferable after the completion of ballast, the contact site of isostere and sea bed, and when being washed away by stormy waves, isostere can be rapidly
Automatic compensation, adheres to sea bed, stormy waves is avoided further to draw the basic part of brush dam body.
Due to completely spreading structure, three layers of compound, full sand rib ballast using elongated, and suitable performance indicator is determined so that
There is isostere enough intensity, the influence for the resistance and its own gravity that when mattress sinking operation will not be formed by water impact to cause
Isostere tearing damage；Compactness：Soft raft attaches river (sea) bed, can effectively prevent flow by river (sea) bed soil particle from isostere
Gap taken away by scour and cause slope foot unstable failure；Flexibility：Soft raft adapts to sea bed and takes up an official post what irregular shape；
Mobility：When differential settlement occurs for the sea bed of soft raft edge or when by water impact scour, isostere adapts to deform,
Automatic compensation, and the further technique effects such as destruction can be prevented.Under the interference for ensureing external working condition, reach reduction stormy waves
To the technique effect for washing away, improving construction quality and stability and uniform settlement of sea bed.
Since utility model uses above-mentioned technical proposal, the stability of foundation construction is greatly reinforced, engineering matter is improved
Amount and uniform settlement, thoroughly solve and have bad luck, lift difficulty, and alluvion is serious, the difficult points such as perishable aging of isostere, while this
Invention also has simple in structure, easy for construction, the advantages that reducing cost.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
