Reinforcing treatment method for area containing unbackfilled trench backfill loose and mixed soil
The invention discloses a reinforcing treatment method for an area containing unbackfilled trench backfill loose and mixed soil. The reinforcing treatment method involves an improved three-pipe jet grouting method and an improved pneumatic down-the-hole hammer vibration jet grouting pile method, the improved three-pipe jet grouting method is used for the part where the filled soil is relatively loose and free of large blocks of concrete, stones and reinforced concrete inner supporting beams or CFG pile heads, and jet grouted cement paste and glassy water are used for mixing and reinforcement;and the improved pneumatic down-the-hole hammer vibration jet grouting pile method is used for the part where the filled soil contains large blocks of concrete, stones and reinforced concrete inner supporting beams or CFG pile heads, large obstacles are broken through vibration of a pneumatic down-the-hole hammer, and a diagram presents that jet grouted cement paste and glassy water are used for mixing and reinforcement. According to the reinforcing treatment method, construction waste concrete blocks, stones, reinforced concrete beams and even tens of thousands of CFG pile heads are adopted for filling the unbackfilled trench and a connected area thereof to naturally reduce the outward transportation cost and serve as filling materials at the same time, so that materials are saved, the quality, safety and rapidness are guaranteed, economy and environment friendliness are achieved, and adverse effects of a traditional treatment method on pipelines and the like are overcome.
一种含肥槽回填虚杂土区域的加固处理方法，包括改良三管旋喷法和改良风动潜孔锤振动旋喷桩法，该改良三管旋喷法用于填土比较虚，没有大块混凝土、石块、钢筋混凝土内支撑梁或CFG桩头部位，利用旋喷水泥浆和玻璃水混合加固；该改良风动潜孔锤振动旋喷桩法用于填土中有大块混凝土、石块、钢筋混凝土内支撑梁或有CFG桩头部位，利用风动潜孔锤振动破碎大块障碍物，图示旋喷水泥浆和玻璃水混合加固。本发明由于肥槽及其相连区域采用了建筑垃圾混凝土块、石块、钢筋混凝土梁甚至上万个CFG桩头填筑，自然减少了外运的成本，同时当成了填筑材料，节约了材料，保证了质量、安全、快捷又经济环保，克服了传统处理方法对管线等不利影响。
