Construction method for laterally penetrating through high-pressure tower group by using shield tunneling machine
The invention discloses a construction method for laterally penetrating through a high-pressure tower group by using a shield tunneling machine, and relates to the technical field of shield tunneling machine construction. According to the construction method, the construction site is leveled according to construction requirements; the positions of pile holes are determined around a high-pressure tower, and the pile holes are arranged in a U shape; and positioning is performed according to the designed diameter and spacing of the pile holes, and marking is performed. According to the construction method, the ground U-shaped steel pipe pile reinforcement and in-tunnel deep hole grouting reinforcement mode is adopted, the reinforcement process is simple, the operability is high, the reinforcement effect is obvious, the influence on the high-pressure tower in the shield crossing process is small, the safety coefficient is high, the construction risk is effectively reduced, deformation such as large settlement and inclination caused by shield crossing through the high-pressure tower is avoided, the safe and normal operation of existing buildings is guaranteed, and social and economic benefits are good.
本发明公开了一种使用盾构机侧穿高压塔群施工工法，涉及盾构机施工技术领域。本发明根据施工要求对施工场地进行平整；围绕高压塔确定桩孔位置，所述桩孔成U型布置；根据设计的桩孔孔洞直径、间距进行定位，并进行标记。本发明采用地面U型布置钢管桩加固及隧道内深孔注浆加固方式，加固工艺简单，可操作性强，加固效果显著，盾构穿越过程中对高压塔影响小，安全系数高，有效降低施工风险，避免因盾构穿越高压塔出现较大沉降及倾斜等变形，保证现有建构筑物安全正常运营，社会和经济效益好。
