Protection method for tunnel laterally penetrating high-rise structure
The invention discloses a protection method for a tunnel side penetrating high-rise structure. The protection method comprises the following steps that S1, two rows of grouting steel pipe piles are driven, top beams are arranged on the tops of the grouting steel pipe piles, holes are formed in the pipe walls of the grouting steel pipe piles, steel pipe pile grouting bodies are injected into surrounding soil, and after the steel pipe pile grouting bodies are solidified, the steel pipe pile grouting bodies and the grouting steel pipe piles jointly form isolation piles; s2, arranging double rows of sleeve valve pipes along the periphery of the high-rise structure foundation close to the tunnel side; s3, two diagonal draw bars are arranged, the tops of the diagonal draw bars are connected with the high-rise structure, and the bottoms of the diagonal draw bars are connected with diagonal draw bar ground anchoring parts anchored underground; s4, according to differential settlement monitoring data of the high-rise structure foundation, compensating grouting is conducted in time through the pre-buried sleeve valve pipe; the method has three protection measures, and is a comprehensive protection system integrating stratum displacement separation, foundation compensation grouting and inclined pull rod inclination control.
本发明公开了一种隧道侧穿高耸结构的保护方法，包括以下步骤：S1、打设两排注浆钢管桩，注浆钢管桩顶设冠梁，注浆钢管桩管壁开孔，向周围土体注入钢管桩注浆体，钢管桩注浆体凝固后与注浆钢管桩共同形成隔离桩；S2、沿靠近隧道侧的高耸结构基础外围打设双排袖阀管；S3、设置两道斜拉杆，斜拉杆顶部与高耸结构连接，斜拉杆底部与锚固在地面以下的斜拉杆地面锚固件连接；S4、根据高耸结构基础差异沉降监测数据，及时通过预埋的袖阀管进行补偿注浆；本发明具有三道保护措施，是一套融合了“隔断地层位移+基础补偿注浆+斜拉杆倾斜控制”的综合全面的保护体系。
