Description
Technical field
The utility model is related to a kind of earth-rock cofferdam structures suitable for coastal profundal zone.
Background technology
Sea wall is first of barrier for defending storm tide and wave, during sea wall development, with filling out extra large fill
Depth it is increasing, gradually develop to ▽ -3.0m very from original 85 elevation of beach (abbreviation elevation, the same below) for ▽ 0.0m
Fill out extra large fill on to deeper beach, corresponding water drainage is drawn building for tide lock and is also constantly being promoted to profundal zone, due to it is coastal easily by
Platform flood influences, and the key that sluice is built in profundal zone is the construction cofferdam system that quickly formed securely, in enclosing for profundal zone
Weir form generally has two kinds of steel sheet-pile cofferdam and earth rock cofferdam, and can the difficult point in cofferdam just in all-weather seawater in the earthwork of holding one's breath
It is quickly and effectively completed in the case of immersion and tidal scour.Can coffering function on schedule, be related to sluice construction
It can complete safe efficiently.
Utility model content
The purpose of this utility model is of the existing technology in order to solve the problems, such as, is provided a kind of suitable for coastal profundal zone
Earth-rock cofferdam structure, in the case where ensuring cofferdam safety, economical rationality, shorten the duration, improve economic benefit.
The technical solution adopted in the utility model is：A kind of earth-rock cofferdam structure suitable for coastal profundal zone, feature
It is to include main dike and small dike, main dike and small dike are jackstone structure sheaf, and earthwork combination knot of holding one's breath is set between main dike and small dike
The joint setting rock ballast bed course and composite earthwork layer of cloth of structure, cubic metre of earth structure of holding one's breath and jackstone, cubic metre of earth structure of holding one's breath and jackstone
Joint sets gradually rock ballast bed course, composite earthwork layer of cloth, a cubic metre of earth structure sheaf of holding one's breath, argillic horizon, rock ballast bed course from bottom to top.
The jackstone structure sheaf includes 50kN Woven geofabrics, blotter and 120kN Woven geofabrics from bottom to top.
Hold one's breath beach mud layer, sand clean out pipe bag layer and the mountain skin soil that cubic metre of earth structure includes setting gradually from bottom to top is filled out
Build layer.
20-25m below beach mud layer sets drain bar, and the drain bar is arranged at intervals.
Cubic metre of earth structure construction height difference of holding one's breath arrives 6.5m for -3.5m, in total 10m.
The utility model uses rock ballast bed course and composite earthwork cloth in the earthwork of holding one's breath with jackstone joint, can not only be used for anti-filter
Layer can partly play the role of protection against erosion again.Cubic metre of earth compound section of holding one's breath is composed of three kinds of different materials, gives full play to difference
The advantage of material, avoids the weakness of different materials, has not only reached good and has held one's breath effect but also shorten the duration, and reduce and make
Valency.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
A kind of earth-rock cofferdam structure suitable for coastal profundal zone as shown in Figure 1, including main dike 6 and small dike 1, main dike with
Small dike is jackstone structure sheaf, and hold one's breath a cubic metre of earth composite structure, cubic metre of earth structure of holding one's breath and the phase of jackstone are set between main dike and small dike
It connects and locates 2 setting rock ballast bed courses and composite earthwork layer of cloth, the joint of cubic metre of earth structure of holding one's breath and jackstone sets gradually stone from bottom to top
Slag bed course, composite earthwork layer of cloth, a cubic metre of earth structure sheaf of holding one's breath, argillic horizon, rock ballast bed course.
Jackstone structure sheaf includes 50kN Woven geofabrics, blotter and 120kN Woven geofabrics from bottom to top.It holds one's breath soil
Beach mud layer 3, sand clean out pipe bag layer 4 and the Shan Pi soil that square structure includes setting gradually from bottom to top fill layer 5.
20-25m below beach mud layer sets drain bar, and the drain bar is arranged at intervals.State a cubic metre of earth structure construction of holding one's breath
Height difference is -3.5m to 6.5m, in total 10m.
Cubic metre of earth compound section of holding one's breath is composed of three kinds of different materials, and lowest part fills that effect of holding one's breath is good, adhesive aggregation first
Property good but softer quality beach mud fill, which is also subject to the position of head pressure maximum, and it is also most thick to fill the earthwork；The
Two steps are exactly to suppress hydraulic reclamation pipe bag at platform on the inside of main dike, are superimposed from level to level, are sunk on jackstone suppression platform by gravity pressure
Form one of sand clean out pipe bag wall, which can play the role of good hold one's breath and effect but also play retaining wall；Third walks
It fills the mountain skin soil on top and suitably makes real, rolls, to allow it that can preferably play effect of holding one's breath
The utility model construction process is as follows：
Preparation of construction → finishing cofferdam small dike and main dike side slope → cofferdam small dike and main dike are laid with 400g/m2 and answer at ebb tide
Geotextiles → hopper throwing beach mud is closed to position → suppress on the inside of the main dike of cofferdam to ▽ 1.5m → first layer sand clean out pipe bag
6 layers of sand clean out pipe bag of position of platform hydraulic reclamation make its be gradually sink to suppression platform on → between sand clean out pipe bag barricade and cofferdam main dike throwing
Mountain skin soil to ▽ 6.5m and suitably make real, roll → cofferdam draining and modify native side slope of holding one's breath.
The utility model using the effect of holding one's breath of beach mud, the earth-retaining of sand clean out pipe bag hold one's breath effect, mountain skin soil it is quick easily
Molding effect is combined, and is formd coastal profundal zone earth rock cofferdam and is held one's breath native compound section.In the earthwork and the jackstone joint of holding one's breath
Using rock ballast bed course and composite earthwork cloth, can not only be used for loaded filter can partly play the role of protection against erosion again.
Listed above is only specific embodiment of the utility model, and the utility model is not limited to above embodiment,
The shape in pond and the shape of steel pipe can also there are many deformation (such as oval, rectangular).Those of ordinary skill in the art
All deformations that directly can be exported or associate from the utility model disclosure, are considered as the protection of the utility model
Range.
