Abstract
The present invention relates to a slope protection technique for side slopes of the bottomland surface facing tide in coast areas, which belongs to the sludge coast sea shelter ecology sludge guiding and slope protecting technique. The present invention has the technique that a tide facing slope is built along the coast; the tide facing slope is composed of an intertidal zone, a supralittoral zone and a levee crown; different plants are planted on the intertidal zone, the supralittoral zone and the levee crown can effectively defend against scouring force of the tide; spartina alterniflora has the functions of tide blocking, silt guiding and bottomland surface raising. The present invention can also improve the green environment of coast areas and prevent impact of tide and storm.
Description
The present invention relates to the seashore area and meet the slope protecting technique of tidal flat face side slope, it belongs to a kind of sludge seashore sea shelter ecology sludge guiding slope protecting technology.
The coastal area generally mostly is the multiple district of storm tide, and each strong tide causes loss in various degree all can for national economy, people's lives, road traffic later.Efficiency in Buildings in Tianjin Area also is one of multiple district of storm tide.Make the coastal tidal level surge in Tianjin to 6.14 meters as 1992 No. 9216 strong tides, higher 1.14 meters than Haihe River gate crest level, the instantaneous maximum in river mouth, Haihe River is poured in down a chimney flow and is reached 700 cubic metres of per seconds, more than the 150 kilometer casual water of sea retaining, nearly 1/3 sea retaining is subjected to heavily to ruin, and direct economic loss is about 400,000,000 yuan according to estimates.People propose various countermeasures for the destruction that this natural calamity causes with loss; Increasing the sea retaining is prevailing mode.Wherein stone matter sea retaining is many constructs with cement mortar, and advantage is that shaping is fast, outward appearance is good, firm; But the cost height makes rhizome exposed through seawater scouring for a long time easily, and maintenance operation takes investment greatly.
The object of the present invention is to provide a kind of sludge seashore sea shelter ecology sludge guiding slope protecting technology, this technology can increase sea retaining beach face elevation, and can afforest on the retaining slope of constructing, sea, plays the effect that the wave that disappears draws silt, raises beach face.
Above-mentioned purpose realizes with this technical scheme: the sludge seashore sea shelter ecology sludge guiding slope protecting technology, and it is to construct upstreaming slope at littoral zone, its upstreaming slope is made of intertidal zone, supratidal zone and levee crown; The gradient of its middle intertidal zone is 1: 25, absolute altitude 2.6-3.6 rice, plants the Spartina alterniflora on this intertidal zone; The gradient of its supratidal zone is 1: 20, and absolute altitude 3.6-5.0 rice is planted Chinese tamarisk on supratidal zone; The gradient of its levee crown is 1: 2.5, and absolute altitude 5.0-7.5 rice is planted Chinese tamarisk on levee crown, and the training ground cover plant is carried in the levee slope both sides.
The intertidal zone of its upstreaming slope, supratidal zone and levee crown plant growing soil underlayer all adopt bay mud, alkaline residue combination soil to carry out hydraulic reclamation and reinforce.
Its levee crown place leaves 2 meters wide solid roof panel, plants Chinese tamarisk on the platform.
4 meters wide reinforcing platform can be set at levee crown 5 meters absolute altitude places thereafter and reinforce platform place plantation Chinese tamarisk or arbor species.As shown in the figure.
Fig. 1 is a generalized section of the present invention.
Wherein, the 1-upstreaming slope, the 2-intertidal zone, the 3-supratidal zone, the 4-levee crown, the 5-Spartina alterniflora, the 6-Chinese tamarisk, 7-levee crown platform, the 8-levee slope, the 9-ground cover plant, 10-reinforces platform, 11-road, 12-sea level.
Characteristics of the present invention are: 1, and adopt bay mud and alkaline residue composite soil hydraulic reclamation to reinforce the sea The shelves upstreaming slope both reached the purpose of the waste residue of dissolving, twice laid, guaranteed again its soil property Permeability is strong, and the sea shelves soil body salt content of constructing with bay mud is 3.2%, is conducive to plant The thing growth; 2, plant the Spartina alterniflora at upstreaming slope, can slacken Wave energy, effectively Weaken tide to the scouring force of sea shelves and can draw to become silted up and raise beach face, play bank protection and protect bank Ecological functions; 3, utilize the Hua Micao that protects that the seawater irrigation intertidal zone plants; 4, adopt The sea shelves that this technology is built not only can be resisted strong damp storm, also can be by planting mutually flower rice The plant landscape seashores such as grass and Chinese tamarisk are improved the ecological environment.
Details are as follows for specific embodiments of the invention:
As shown in Figure 1: construct the upstreaming slope 1 that utilizes low-position vacuum technology hydraulic reclamation bay mud and alkaline residue combination soil to make on coastal limit, littoral zone area, and make upstreaming slope 1 be divided into intertidal zone 2, supratidal zone 3 and levee crown 4; The gradient be 1: 25, absolute altitude 2.6-3.6 rice (Dagu, Tianjin elevation, down with), length of grade 55-60 rice district as intertidal zone 2, plantation Spartina alterniflora 5 behind backfill planting soil on the intertidal zone; The gradient 1: 20, absolute altitude 3.6-5.0 rice, the about 30 meters districts of length of grade are as supratidal zone 3, thereon backfill planting soil and plant Chinese tamarisk 6; The gradient is at 1: 25, absolute altitude 5.0-7.5 rice, and 6 meters left and right sides lengths of grade are established in both sides, and the part that 2 meters levee crown platforms 7 are built in the centre is a levee crown 4, and backfill planting soil and plant Chinese tamarisk 6 on levee crown platform 7 is laid lawn class ground cover plant 9 on the both sides levee slope 8; In upstreaming slope 1 back, it is high 5 meters to utilize bay mud and alkaline residue combination soil to construct at last, the reinforcing platform 10 that platform is wide 4 meters, and plant arbor species thereon.This reinforcing platform 10 can effectively support levee crown 4 and resist the tide impact.
Claims (3)
1, a kind of muddy coast sea shelves ecology is drawn the silt slope protecting technique, it is characterized in that, it is to construct upstreaming slope at littoral zone, and upstreaming slope is made of intertidal zone, supratidal zone and levee crown, wherein, the gradient of intertidal zone is 1: 25, and absolute altitude 2.6-3.6 rice is planted the Spartina alterniflora on this intertidal zone; The gradient of its supratidal zone is 1: 20, and absolute altitude 3.6-5.0 rice is planted Chinese tamarisk on supratidal zone, and the gradient of its levee slope is 1: 25, and absolute altitude 5.0-7.5 rice is planted Chinese tamarisk on levee crown, the levee slope both sides ground cover plant of planting; The planting soil underlayer of upstreaming slope all adopts bay mud, alkaline residue combination soil to carry out hydraulic reclamation and reinforce.
