新型锚固式抗浮锚杆施工及溶洞位置判断技术应用

Application of New Anchored Anti Floating Anchor Construction and Karst Cave Position Determination Technology

以南京市仙林中医医院项目为例,因施工区域地下溶洞较多,施工环境复杂,为有效地判断溶洞的位置,并保证施工质量,介绍了一种新型锚固式抗浮锚杆施工技术。该施工技术采用了高强钢筋锚杆,利用端头锚固板的形式代替钢筋直接锚固的形式。经实践证明,该施工技术在保证施工质量的同时,可有效节约施工成本,具有明显的社会和经济效益,可为类似工程提供借鉴。

Taking the project of Xianlin Hospital of traditional Chinese medicine in Nanjing as an example,because there are many underground Karst caves in the construction area and the construction environment is complex.In order to effectively determine the location of Karst caves and ensure the construction quality,this paper introduces a new type of anchored anti floating anchor construction technology.In this construction technology,high-strength steel bar anchor is used,and the form of end anchor plate is used to replace the form of direct anchorage of steel bar.The practice shows that the construction technology can effectively save the construction cost while ensuring the construction quality,and has obvious social and economic benefits,which can provide reference for similar projects.
