Silt slope stability control method for fixing slope by using chemical improvement reagent
The invention discloses a silt slope stability control method for fixing slope by using a chemical improvement reagent. The method comprises the following steps that 1) the chemical improvement reagent, which is a mixed solution of lime, sodium silicate, silica powder or calcium lignosulphonate and water, is prepared; 2) a chemical improvement reagent is put into a solution tank; 3) a plurality of grouting steel pipes are sequentially pressed into a silt layer of the side slope, and the grouting steel pipes are connected through grouting pipe connecting valves till the total length of the grouting steel pipes reaches the designed depth; 4) a grouting hose is connected between the solution tank and the grouting steel pipes, and a grouting pump is arranged on the grouting hose; 5) a grouting pump is started, a chemical improvement reagent is injected into the silt layer, and the grouting steel pipes are gradually lifted until the grouting steel pipes are separated from the ground surface; 6) the grouting pump is closed, and the grouting steel pipes are disassembled; and 7) the steps 3)-6) are repeated, and construction of the next grouting point is conducted till grouting is completed in all the set areas of the slope. According to the method, the internal friction angle and cohesive force of silt are increased through the chemical improvement reagent, and slope reinforcement is achieved.
本发明公开了一种利用化学改良试剂固坡的粉土边坡稳定性控制方法，包括以下步骤：1)配置化学改良试剂，化学改良试剂为石灰、硅酸钠、硅微粉或木质素磺酸钙与水的混合液；2)将化学改良试剂放入溶液池；3)将若干注浆钢管依次压入边坡的粉土层，注浆钢管之间采用注浆管连接阀连接，直到若干注浆钢管的总长度达到设计深度；4)将注浆软管的连接在溶液池与注浆钢管之间，注浆软管上设置注浆泵；5)开启注浆泵，将化学改良试剂注入粉土层，并逐渐提升注浆钢管直至脱离地表面；6)关闭注浆泵，拆解注浆钢管；7)重复步骤3)～6)，进行下一个注浆点的施工，直到边坡设定的区域均完成注浆。本发明通过化学改良试剂增大粉土的内摩擦角及粘聚力，实现边坡的加固。
