Problems solved by technology

[0005] The technical problem mainly solved by the present invention: currently cement and water sand are generally used as raw materials in the reinforcement and manufacture of embankments, not only the cost is relatively high, but also it is easy to crack, resulting in weak foundation, and it will not be effective when encountering floods or heavy rainfall. In view of the disadvantages of blocking, a method of using dredging fill to reinforce the embankment is provided. This method first uses steel bars to build a trapezoidal embankment footing, and then mixes the dredging fill with cobblestone, quicklime, aggregated organic matter, coarse sand, and medium sand respectively. Mix them separately, then place them in terraced embankments in turn, and finally add grass and trees on the reinforced embankments, which not only reduces the amount of cement used, but also saves costs, and the material made by this method has a significant reinforcement effect. The upper trapezoidal embankment is designed so that trucks weighing more than 2.5 tons can drive stably within 3 to 5 days after the embankment is built

example 1

[0018] Use an excavator to dig a river embankment with a bottom width of 5m, a sill height of 1.5m, a sill width of 1m, and a slope of 45°, and lay a steel bar every 20cm on the bottom of the terraced embankment and the slopes on both sides. A layer of cement with a thickness of 2cm, let it air dry for 3 days, and let it dry naturally; first, dig out 10kg of dredged fill soil from the river, add 5kg of pebbles and 3kg of water, stir clockwise for 20 minutes until it becomes muddy, and then mix the mud The mixture is uniformly irrigated on the bottom of the above-mentioned embankment dug, with a thickness of 35cm. After it is naturally air-dried for 1 day, the water will be lost to a semi-dry state. Stir clockwise, add 2kg of quicklime at the same time during the stirring process, continue to stir for 15 minutes until it becomes viscous, and then evenly irrigate the viscous mixture on the above-mentioned river embankment with the bottom layer laid, and the laying thickness is 25...

example 2

[0021] Use an excavator to dig a river embankment with a bottom width of 8m, a sill height of 1.8m, a sill width of 1.5m, and a slope of 45°, and lay a steel bar every 23m on the bottom of the terraced embankment and the slopes on both sides. After laying, paint The upper layer of cement with a thickness of 2.5cm, let it air dry for 3.5 days, and wait for it to dry naturally; first, dig out 13kg of dredged fill soil from the river, add 6kg of pebbles and 4kg of water, stir clockwise for 23min until it becomes muddy, and then mix the The mud-like mixture is evenly irrigated on the bottom of the above-mentioned embankment dug, with a thickness of 40cm. After it is naturally air-dried for 1.5 days, the water will be lost to a semi-dry state. Organic matter, stir clockwise, add 3kg quicklime at the same time during the stirring process, continue to stir for 18 minutes until it becomes viscous, and then evenly irrigate the viscous mixture on the above-mentioned river embankment with...

[0024]Use an excavator to dig a river embankment with a bottom width of 10m, a sill height of 2m, a sill width of 1.5m, and a slope of 45°, and lay a steel bar every 25cm on the bottom of the terraced embankment and the slopes on both sides. A layer of cement with a thickness of 3cm, let it air dry for 4 days, and wait for it to dry naturally; first, dig out 15kg of dredged fill soil from the river, add 7kg of pebbles and 5kg of water, and stir clockwise for 25 minutes until it becomes muddy. The mixed mixture is evenly irrigated on the bottom of the above-mentioned embankment dug, with a thickness of 45cm. After it is naturally air-dried for 2 days, the water will be lost to a semi-dry state. Stir clockwise, add 5kg of quicklime at the same time during the stirring process, continue to stir for 20 minutes until it becomes viscous, and then evenly irrigate the viscous mixture on the above-mentioned embankment with the bottom layer laid, the laying thickness is 38cm, wait for it...

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 [0001] The invention relates to a method for reinforcing river embankments by using dredging filling soil, and belongs to the technical field of foundation treatment. Background technique [0002] Embankments are water-retaining structures built along rivers, channels, lakes, coasts, flood diversion areas, and edges of reclamation areas. Building embankments can resist floods, block tides and waves, and protect the safety of residents and industrial and agricultural production inside the embankments. It is the earliest and widely used flood control engineering measure in the world. According to the location of the embankment, it can be divided into river embankment, lake embankment, sea embankment, canal embankment and embankment. Embankments are generally constructed of earth materials. Where rivers pass through cities and towns, reinforced concrete or mortar block stone embankments, also known as flood walls, can also be used in order to occupy less land ...
