Method for combining microorganism and anchor cable to reinforce sandy road cutting high slope and device thereof
The invention discloses a method for combining a microorganism and an anchor cable to reinforce a sandy road cutting high slope and a device thereof. The method for combining the microorganism and theanchor cable to reinforce the sandy road cutting high slope comprises the steps of pile hole excavation, first grouting of first row of pile holes, the first grouting of second row of pile holes, secondary grouting of the first row of pile holes, the secondary grouting of the second row of pile holes, three grouting and molding of the first row of pile holes, and the three grouting and molding ofthe second row of pile holes. The device used the method for combining the microorganism and the anchor cable to reinforce the sandy road cutting high slope comprises a mixing device, an anchor cableand a drainage device. The construction is relatively simple, and the application of metal pipe piles effectively reduces the risk of collapse, forming a composite slope reinforcement treatment system of microbial piles, metal hollow pipe piles, anchor cables, and solidified sand bodies between piles. The problems of shallow local failure and deep overall failure of sandy slope are solved effectively. Compared with an existing microbial solidification (such as MICP) technology, the mixing and pouring of sand, microbial bacteria liquid, and nutrient solution effectively solves the problem of uneven solidification phenomenon in MICP technology and effectively improve the strength of the solidified soil
本发明公开了一种微生物与锚索联合加固砂质路堑高边坡方法及装置，该方法包括桩孔开挖、首排桩孔首次灌浆、次排桩孔首次灌浆、首排桩孔二次灌浆、次排桩孔二次灌浆、首排桩孔三次灌浆成型、次排桩孔三次灌浆成型；该装置包括拌合装置、锚索和排水装置。本发明施工较为简单，金属管桩的应用，有效降低了塌孔风险，形成微生物桩体、金属中空管桩、锚索、桩间固化砂体的复合边坡加固处理体系，有效解决了砂质边坡浅层局部破坏与深部整体破坏问题，与现有的微生物固化(MICP)技术相比，通过砂、微生物菌液、营养液三者的拌合与灌注，有效解决了MICP技术中固化不均匀现象，有效提高固化土体的强度。
