Abstract
The invention relates to a method for reinforcing a river bank by utilizing dredger fill, belonging to the technical field of foundation treatment. The method provided by the invention comprises the following steps: firstly making a trapezoidal river bank foundation by utilizing steel bars; then respectively mixing dredger fill with cobblestone, quicklime, polymeric organic matters, coarse sand and medium sand, and then sequentially putting in a terrace river bank; and finally, planting vegetations on the reinforced river bank. Embodiments prove that the method reduces the cement content and saves the cost, and the material prepared by the method has an obvious reinforced effect; and by virtue of the design of the trapezoidal river bank, after the river bank is built for 3-5 days, a truck of which the weight is more than 2.5-3.5t can steadily run on the river bank.
Description
Technical field
The present invention relates to a kind of method utilizing barged-in fill to reinforce river levee, belong to foundation treatment technology field.
Background technology
River levee, along rivers, channel, lake, seashore limit or flood-diversion area, encloses and cultivates the water retaining structure that area edge builds.Fill can resist flooding, keeps off damp wave resistance, and the safety of resident and industrial and agricultural production in protection dike is the structural measures of flood control widely adopted the earliest in the world.River levee, Hu Di, sea wall, canal dike and embankment can be divided into according to the position of dike.Levee body is generally built by earth material.At rivers by location, cities and towns, for account for less soil or because of tide, stormy waves too large, also can adopt steel concrete or cemented rock dike, also known as flood protection wall.
Nowadays natural calamity occurs very frequent in China, wherein especially serious with flood, recent two decades comes, the exploitation of natural resource constantly expand, urban and rural economies build develop rapidly, and the frequency that flood occurs and the loss caused thereof also constantly increase, and more do not carry out the place of riverbank reinforce, seriously flood soil, crops of having destroyed by rush of water, house have caved in, the dead domestic animal of people dies, and make us startling.
At present when reinforcing manufacture river levee, the principle larger according to the darker pressure of water, main employing be trapezium structure, in material, importantly add that fine sand mixes by cement, or be laid to dike by sand hill along river course, have in order to save material, directly used the water grains of sand, these river levees be made up of cement material, cost compare is high, and easily ftracture, ground is not solid; The river levee that direct sand hill or the water grains of sand are made, although cost is cheap, only to block weak middle current, run into flood or heavy showers, cannot effectively stop, consequence is hardly imaginable.Therefore, fast, science, effectively carry out riverbank reinforce, make the direction flowing that river specify according to people, to reduce or to avoid river to be a very important thing for the mankind, social injury.
Summary of the invention
The technical problem that the present invention mainly solves: for generally adopting cement and the water grains of sand to be raw material when reinforcing and manufacturing river levee at present, not only cost compare is high, and easily ftracture, cause ground not solid, run into flood or heavy showers, the drawback that cannot effectively stop, provide a kind of method utilizing barged-in fill to reinforce river levee, first the method utilizes reinforcing bar to make a call to a trapezoidal river levee footing, then by barged-in fill respectively with cobble, quicklime, polymerized organics, coarse sand, medium sand mixes respectively, be positioned over successively afterwards in terraced fields river levee, vegetation in finally on the river levee reinforced, not only reduce cement consumption, save cost, and the material reinforced Be very effective that the method is made, add the design of upper trapezoid river levee, the truck of more than 2.5t of making to weigh builds up at river levee and just can firmly travel afterwards for 3 ~ 5 days.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
(1) a bottom width 5 ~ 10m is dug with excavator, high 1.5 ~ the 2m of bank, wide 1 ~ the 1.5m of bank, Kan Po is the river levee of 45 DEG C, and a reinforcing bar is laid every 20 ~ 25cm in bottom terraced fields river levee and slope, both sides, coating a layer thickness after laying is 2 ~ 3cm cement, hangs 3 ~ 4 days, treats its natural air drying;
(2) first from river course, 10 ~ 15kg barged-in fill is taken, add 5 ~ 7kg cobble and 3 ~ 5kg water, clockwise stirring 20 ~ 25min stops in pureed, afterwards by made pureed mixture uniform irrigation bottom above-mentioned dug river levee, thickness is 35 ~ 45cm,, treat its natural air drying 1 ~ 2 day, make water loss to leather hard;
(3) next from river course, 8 ~ 12kg barged-in fill is taken, add 0.5 ~ 0.8kg polymerized organics, clockwise stirring, add 2 ~ 5kg quicklime in whipping process simultaneously, continue stirring 15 ~ 20min to stop in thick, completed on the river levee of bottom above-mentioned by made viscous mixture uniform irrigation afterwards, laying depth is 25 ~ 38cm, treat its natural air drying 1 ~ 3 day, the PAMC solution of wherein said polymerized organics to be concentration be 0.01 ~ 0.02g/L;
(4) from river course, 5 ~ 18kg barged-in fill is taken again subsequently, add 10 ~ 15kg fine sand, clockwise stirring 15 ~ 20min stops to muddy, afterwards by made muddy mixture uniform irrigation on the above-mentioned two-layer river levee completed, laying depth is 30 ~ 35cm, treats its natural air drying 2 ~ 3 days;
(5) finally from river course, 12 ~ 16kg barged-in fill is taken again, add 8 ~ 14kg coarse sand, clockwise stirring 18 ~ 22min stops in half mud half sand shape, afterwards by half made mud half sand mixture uniform irrigation on the above-mentioned river levee having completed three layers, laying depth is 20 ~ 40cm, treats its natural air drying 3 ~ 5 days;
(6) after 3 ~ 5 days, with road roller, terraced fields river levee surface is rolled, and build regular hexagon flower nursery in smooth ground of rolling successively according to the spacing of 12 ~ 15cm, the every length of side 15cm in flower nursery, hexagon all uses rectangle fragment of brick and cement stabilization, after natural coagulation in 1 ~ 3 day, plant some fast-growing woods sapling and flower seedlings above.
The invention has the beneficial effects as follows:
(1) the material reinforced Be very effective utilizing the method to make, not only effectively can stop the attack of flood or heavy showers, and the truck of more than the 2.5t that makes to weigh builds up at river levee and just can firmly travel afterwards for 3 days;
(2) decrease cement consumption, save cost of production.
