随着城市建设的不断发展,基坑支护为建筑物、构筑物的施工安全带来了安全屏障。加劲碎石注浆桩结合锚杆联合支护不但能提高效率,缩短工期,节约成本,保护环境,而且对临近建筑物、构筑物的影响较小,稳定性较好。本工艺技术是对合肥市城市内涝治理一期工程枞阳路泵站、红旗泵站、胡浅泵站等多个工程的成功经验进行总结而成。其投入设备简单、施工便利、省时省工、降低造价、易于推广。
With the continuous development of urban construction, the foundation pit support has created a safety barrier for the construction safety of buildings and structures. The combination of stiffening stone grouting pile combined with bolt and joint support can not only improve the efficiency, shorten the construction period, save the cost, protect the environment, but also have less influence on the adjacent buildings and structures, and the stability is better. This process technology is a summary of the successful experiences of many projects such as Puyang Road Pumping Station, Hongqi Pumping Station, and Hu-Shiao Pumping Station in the first phase of Hefei City Urban Waste Management. Its input equipment is simple, construction is convenient, time and labor saving, cost reduction, and easy promotion.
