Description
Technical field
The present invention relates to a kind of fill construction method, particularly a kind of clear beach material fill construction method of mountain area middle and small river.
Background technology
Mountain stream is numerous, and river is short, bigger than dropping, cause flood suddenly, go soon, and most of is without dyke or dike
The low river of anti-standard, river flood control ability is low, easily cause mud-rock flow, dyke breaking whenever flood season, destroy by rush of water village and road,
The disasters such as farmland are flooded, and most of middle and small river two sides soil is fertile, densely populated, losses due to flood and waterlogging is larger.
Mountain area middle and small river has that drainage area is small, flow is short, the concentration time is short, stream gradient is big, and Flood
Suddenly rise to fall suddenly, and the time that water flow in dry season very little, the basic cutout having, riverbank or river levee bear high water level pressure is not long, right
The destruction of embankment is relatively small, stream seashore is broad, the embankment gradient is relatively delayed, and height is smaller, is generally that farmland, precipitation fill after dike
It abundant, pleasant Climate, the features such as be conducive to plant growth, should combine actual, suit measures to local conditions in the improvement of mountain area middle and small river,
Safety, ecology are gived top priority, and the nature in river is retained as far as possible, the pattern of ecological management is taken.According to traditional
Great rivers administering method and requirement, river embankment must be filled with homogeneous soil, and the clear beach material in river course cannot be used for fill, because
This, on the one hand, a large amount of mountain area middle and small river harnessing projects transport outward the clear beach material in river course, build stockyard storage, occupy a large amount of soil
Ground, stockyard often turns into problem；On the other hand, homogeneous soil fill is transported into from outside, certain destruction is caused to mountain forest.So, one
Have a try, not only increase investment, waste soil, damaged mountain forest, waste resource, destroy ecology, also, easily increase
Journey and local contradiction are processed, is unfavorable for engineering construction and makes smooth advances.If clear beach material can be used for fill, these problems will all be met
Sword and solve.
The content of the invention
The purpose of the present invention, is to provide a kind of mountain area middle and small river clear beach material fill construction method, it is by using clear
Fill is expected on beach, and having broken fill must be fettered with the traditional thought of homogeneous soil, take the technical measures of easy economy, it is ensured that embankment is steady
Fixed and seepage stability, can both reduce clear beach material outward transport, and can also avoid the transport of fill homogeneous soil, cost saving is also protected
It is ecological.
The present invention solve its technical problem solution be：A kind of clear beach material fill construction method of mountain area middle and small river,
It comprises the following steps,
1）The river shoal boulder and cobble of mountain area middle and small river, sandy soil are removed after debris, are well mixed, levee body is transported to, layering is ground
Densification is real, lift height 30cm~50cm；
2）Side surface is bordered on the river along filling clay core sloping core on slope in levee body, the thickness 30cm of clay core sloping core~
100cm, layered rolling is closely knit, layer height 30cm~50cm；
3）On clay core sloping core surface loaded filter is arranged by graded sand and stone and geotextiles；
4）Bank protection, thickness 20cm~50cm are arranged by block stone, lattice guest protection pad and turf on loaded filter；
5）Spats is arranged by concrete, stone masonry, loose stone, gabion and building block in levee toe.
As the further improvement of above-mentioned technical proposal, in step 5）Afterwards, clear beach is passed through on the riverbed near spats
Boulder and cobble, jackstone, gabion arrangement protection-apron.
As the further improvement of above-mentioned technical proposal, pass through concrete, pitch and mud calculus cloth at the top of the levee body
Road on the bank is put, thickness 10cm~50cm of the road on the bank, road on the bank width is narrower than levee crown width.
As the further improvement of above-mentioned technical proposal, dividing in the layering gap and clay core sloping core in the levee body
Stagger lamellar spacing.
As the further improvement of above-mentioned technical proposal, in step 3）In, the graded sand and stone is put into after geotextiles viscous
Native seepage-proof dip dire surface layout is into loaded filter, thickness 10cm~15cm of graded sand and stone.
As the further improvement of above-mentioned technical proposal, in step 5）In, when the spats is located at thalweg offshore section, Ying Yan
Talweg is extended, and the requirement of riverbed limiting scour should be met；The spats is located at relatively delays section in current smooth-going, bank slope
When, it is l preferably to protect to the gradient：3~1：At 4 gentle slope riverbed, spats width 0.3m to 0.6m, crest level to design low water position.
The beneficial effects of the invention are as follows：The present invention expects fill using clear beach, and the tradition think of of homogeneous soil must be used by having broken fill
Think constraint, take the technical measures of easy economy, it is ensured that embankment stabilization and seepage stability, can both reduce clear beach material outward transport, and also might be used
Avoid the transport of fill homogeneous soil, cost saving, also protecting ecology.
