Construction method for underneath passing of shield tunneling machine through existing building
The invention relates to the technical field of underground space engineering, and particularly discloses a construction method for underneath passing of a shield through an existing building. The raw material ratio of the grouting material is optimized, and the modified mineral wool fiber and the SAP resin are added in the grouting material. When the grouting material is used for grouting operation, corrosion cracks and karst caves in a stratum can be filled, high strength is formed after the grouting material is solidified, under the combined action of the grouting material and a jet grouting pile, stratum reinforcement can be fully achieved, and the grouting effect is good. And the influence on the stratum in the advancing process of the shield tunneling machine is reduced, so that the settlement of the existing building is reduced.
本申请涉及地下空间工程技术领域，具体公开了一种盾构下穿既有建筑物的施工方法。本申请优化了注浆料的原料配比，并在注浆料中新增了改性矿棉纤维和SAP树脂。通过使用本申请的注浆料进行注浆作业，能够对地层中的溶蚀裂隙和溶洞实现填充，并在注浆料固结之后形成较高的强度，在本申请的注浆料以及旋喷桩的共同作用下，有助于充分实现对地层的加固，并降低盾构机行进过程中对地层造成的影响，进而减小既有建筑物发生的沉降。
