Problems solved by technology

[0003] If trees are planted during the renovation of the existing river course, water and soil may be easily lost in the early stage of treatment, especially when the root system of the tree is underdeveloped, and if cement curing is used, the water and soil at the bottom of the cement are likely to be empty, and Unsightly, more choices are to spread cement on the land around the trees, and the side close to the trees is not covered with cement, but in the late growth period of the trees, the cement will limit the continuous growth of the trees, especially There is no way to retain water around the trees, and we must rely on artificial water replenishment, otherwise the trees will easily die due to lack of water. At the same time, the radius of the root system is also greatly limited, and it is easy for the trees to tilt in windy weather.

Abstract

The invention discloses a method for restoring a river channel, and belongs to the field of river channel improvement. The name of the patent is a divisional application of the method for restoring the river channel. The application date is December 31, 2015, and the application number is 2015110124715. The method comprises the steps that 1, the river channel needing to be restored is selected; 2, fly ash concrete is prepared, wherein A, calcium sulfate, sodium sulfate, calcium lignosulphonate and clay are selected, and coagulant is obtained; B, sodium silicate, kieselguhr, pyrrole and ethylenediamine tetraacetic acid disodium salt are added, and a first mixed solution is obtained; C, activated carbon, disodium methylene dinaphthalenesulfonate, borax and gelatin are added; D, a curing agent for treating fly ash is obtained; and E, the fly ash concrete is obtained; and 3, the fly ash concrete obtained in the step 2 is poured onto river levees on the two sides of the river channel. The method saves energy and is environment-friendly, waste is utilized reasonably and efficiently, and meanwhile the problem about water storage and drainage of the river levees is solved.
