Landslide reinforcing method
The invention relates to a landslide reinforcing method. According to the method, a directional drilling machine is adopted for drilling along a sliding face, the ground is led out from the position close to a landslide or the side slope bottom, then the directional drilling machine gradually retreats, and high-pressure grouting or high-pressure jet grouting is conducted for reinforcement along the sliding face. According to the method, linear grouting reinforcement for the sliding surface along a sliding surface hole is conducted, the reinforcement area of the sliding surface is extended, the construction is easy, the controllability is high, the effective length of drill hole reinforcement is large, the drill hole utilization rate is high, the total drilling footage is reduced, the construction efficiency is improved, reinforcement is conducted according to different sliding surface forms and sliding surface soil body properties, the anti-sliding resistance of the sliding surface can be effectively increased, the engineering amount of conventional engineering can be effectively reduced, and the investment is saved on.
本发明涉及一种滑坡加固方法。该方法采用定向钻机沿着滑动面进行钻孔，在靠近滑坡或边坡底部引出地面，然后逐步后退并沿着滑动面进行高压注浆或高压旋喷注浆加固。本发明针对滑动面沿着滑面成孔的线状注浆加固，加大了滑面的加固面积，施工简单，可控性强，钻孔加固的有效长度大，钻孔利用率高，减少了总钻孔的进尺，提高了施工效率，根据不同的滑动面形态及滑动面土体性质进行加固，可有效增加滑动面抗滑阻力，可有效减少常规工程的工程量，节省投资。
