摘要
在四川地区,超高层建筑施工中一般都存在深基坑和抗浮锚杆施工。由于深基坑基岩裂隙水的处理存在难度,基坑四周常规降水井的降水效果只能体现在强透水层。抗浮锚杆施工中,传统方法存在锚杆后期挖土损坏、不利于垫层施工等问题。介绍了深基坑基岩裂隙水的处理办法以及抗浮锚杆后施工法,有效解决了深基坑基岩裂隙水降水难的问题以及传统抗浮锚杆施工存在的诸多不足。
Deep foundation excavations and anti-floating anchor bolt constructions are common in super high-rise buildings in Sichuan. Because of the difficulty in bedrock fissure water treatment, the effect of normal dewater well is not very good. In the traditional anti-floating rock bolt construction method, anchors are subjected to damage in the later phase of construction, which is harmful to the bed course construction. This paper introduced the treatment for bedrock fissure water and the post-construction method for anti-floating rock bolts. The method proposed can effectively solve the difficulties mentioned above.
