Problems solved by technology

[0006] The technical problem mainly solved by the present invention is that the cost is relatively high for these current embankments made of cement materials, and the strength is low, and they are easy to crack. Inability to effectively block floods or the turbulent water flow caused by heavy rainfall provides a method to strengthen river embankments

Embodiment Construction

[0026]Put the secondary sedimentation sludge in the sludge dehydrator for 30-40 minutes, put it into the oven, heat up to 70-80°C, and dry it for 4-5 hours to obtain the dewatered sludge. The dewatered sludge, fly ash and The montmorillonite clay is mixed according to the mass ratio of 5:1:2, placed in a ball mill and milled for 3-4 hours, and passed through a 200-mesh sieve to obtain a mixed powder; add 700-800mL water to 2-3kg of the above-mentioned mixed powder, put Make raw meal balls with a particle size of 2-3mm in the ball making machine, place the raw meal balls in an oven with a set temperature of 100-110°C, dry for 2-3 hours, put them in a muffle furnace, and heat up to 400 °C ~450℃, preheat for 10~15min, then raise the temperature to 1100~1150℃, roast for 15~20min, stop heating, cool down to room temperature naturally, discharge the material to obtain ceramsite; place the acid-leached manganese slag in the vibrating sieve machine to sieve After 30-40 minutes, separa...

Abstract

The invention belongs to the technical field of river levee reinforcement, and particularly relates to a river levee reinforcing method. According to the river levee reinforcing method, ceramic particles are obtained with secondary settling sludge as raw materials, pre-treated acid-leached manganese slag is obtained by recovering acid-leached manganese slag, and finally, the ceramic particles, clay, the pre-treated acid-leached manganese slag and the like are mixed to obtain a cement-based mixture; biomass solid glue is obtained with corn starch as raw materials; the cement-based mixture is poured onto a bottom foundation of a to-be-reinforced river levee; an expansive cement layer is surrounded by impermeable cloth; and biogas slurry is poured from the top of the expansive cement layer, so that the river levee is reinforced. According to the river levee reinforcing method, gypsum can promote agglomeration of particles in the expansive cement layer, so that the expansive cement layer has high strength; moss and algae can grow on the surface of the impermeable cloth to distribute impetuous water flow, so that the impact strength of the water flow is weakened; meanwhile, the moss andthe algae can also be used as filler to fill cracks in the river levee, so that the strength of the river levee is improved; and the river levee reinforcing method has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of embankment reinforcement, and in particular relates to a method for embankment reinforcement. Background technique [0002] Rivers are crucial to the survival and development of rural areas. With the rapid development of rural construction and agricultural production, rivers in rural areas are greatly disturbed, and the shape of rivers tends to be discontinuous. The diversity of river ecological environments and ecosystem functions subject to varying degrees of degradation and destruction. [0003] At present, most of the embankments made of earth, large rocks, concrete or sandbags are used as river water retaining structures in our country. During the construction of existing embankments, it is often necessary to drain the river. When large rocks are used as river channel water retaining structures, the mining of rocks destroys the mountain body, and at the same time consumes a lot of manpower and mate...
