Bio-enzyme curing material and cured silty soil roadbed combination part and construction process for reinforcing roadbed by sand compaction piles
The invention belongs to the field of road engineering, and relates to a bio-enzyme curing material and cured silty soil roadbed combination part and a construction process for reinforcing a roadbed by a sand compaction pile, which comprises the following steps of expanding and culturing a bio-enzyme material in advance, widening a new silty soil roadbed and an old silty soil roadbed by using thebio-enzyme material, and constructing the sand compaction pile. The bio-enzyme is an A-type bio-enzyme material composed of iron bacteria and carbonate mineralizing bacteria and a B-type bio-enzyme material composed of urease. The invention innovatively solves the problems that the joint of the new and old silt subgrade is difficult to treat and the compacted sand pile is difficult to reinforce; the old road is still kept in an operation state; the new roadbed is subjected to widening construction, traffic pressure is relieved, differential settlement of the new roadbed and the old roadbed iseffectively reduced, the shear strength of a soil body is improved, the integrity of the new roadbed and the old roadbed is guaranteed, the advantages of being environmentally friendly, easy to operate and high in construction workability are achieved, innovation of the construction technology and progress of the traffic engineering field are facilitated, and more value is created.
本发明属于道路工程领域，涉及一种生物酶固化材料与固化粉质土路基结合部及挤密砂桩加固路基施工工艺，包括预先扩大化培养生物酶材料，然后运用生物酶材料进行新旧粉土路基拼宽及挤密砂桩的施工。所述的生物酶为铁细菌和碳酸盐矿化细菌组成的A型生物酶材料及由产脲酶组成的B型生物酶材料。本发明创新性地解决粉土新旧路基结合部难处理和挤密砂桩难加固的问题，在保证旧路仍保持运营状态下，新路基进行拼宽施工，缓解了交通压力，有效减少了新旧路基的不均匀沉降，提高了土体的抗剪强度，保证了新老路基的整体性，具有环保，操作简单，施工和易性较高的优势，有助于施工技术的革新和交通工程领域的进步，创造更多的价值。
