Microorganism grouting treatment soft foundation construction structure and construction method thereof
The invention relates to a microorganism grouting treatment soft foundation construction structure and a construction method thereof.According to the scheme, pile loading, microorganism high-pressure jet grouting piles and microorganism tree root steel pipe piles are arranged, so that the shear strength and bearing capacity of a soft foundation are improved, and the compressibility and water permeability of foundation soil are reduced; the water in the foundation is discharged and the liquefaction characteristic of the soil body of the foundation is eliminated or weakened by matching the stacking with the drainage steel floral tube, the net-shaped water collecting pipeline and the water pump; and by arranging the microorganism sand soil solidification layer, the cooperative work capacity of the microorganism high-pressure jet grouting piles and soil between the piles is improved, deformation coordination is guaranteed, and differential settlement is prevented. The grouting material is a double-component microbial grouting material which is safe, clean and environment-friendly, and the microbial induced calcium carbonate precipitation material has the advantages of high speed and high efficiency, and can finish induced precipitation of calcium carbonate in about several hours, so that the construction period is greatly shortened, and the consequences of sewage cross flow and environmental pollution are avoided.
本申请涉及一种微生物注浆处理软基施工结构及其施工方法，该方案包括通过堆载、微生物高压旋喷桩和微生物树根钢管桩的设置，提高软基的抗剪强度和承载力，降低地基土的压缩性和透水特性；通过堆载配合排水钢花管、网状集水管道和抽水机，排出地基中的水分，消除或减弱地基土体的液化特性；通过设置微生物砂土固化层，改善微生物高压旋喷桩和桩间土的协同工作能力，保证变形协调，防止不均匀沉降。注浆材料采用双组份微生物注浆材料，安全、清洁、环保，且微生物诱导碳酸钙沉淀材料具有速度快、效率高的优点，可在几个小时左右完成碳酸钙的诱导沉淀，极大地缩短了工期，不会造成污水横流、污染环境的后果。
