High polymer grouting treatment soft foundation construction structure and construction method thereof
The invention relates to a high polymer grouting treatment soft foundation construction structure and a construction method thereof.According to the scheme, pile loading, high polymer high-pressure jet grouting piles and high polymer 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 high polymer gravel solidification layer, the cooperative work capacity of the high polymer high-pressure jet grouting piles and soil between the piles is improved, deformation coordination is guaranteed, and differential settlement is prevented. The grouting material adopts a double-component quick-setting expansive high polymer material, the components are simple, the setting time is short, and the consequences of sewage cross flow and environmental pollution are not caused.
本申请涉及一种高聚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、高聚物高压旋喷桩和高聚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；通过设置高聚物碎石固化层，改善高聚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。注浆材料采用双组分速凝、膨胀性的高聚物材料，组分单纯，凝固时间快，不会造成污水横流、污染环境的后果。
