介绍了钢筋混凝土桩网复合地基加固技术的机理、工艺以及在我国第一条无碴轨道试验段上的应用情况。结合工程实例,阐述了采用长螺旋钻机在岩层中成孔,用电流法控制钻头的入岩深度以及利用钻机进行先灌混凝土后插钢筋笼等关键施工技术,为我国的客运专线建设提供借鉴。
The mechanism, technology and application of reinforcement technology of the composite foundation of the reinforced concrete pile net are introduced in the first ballastless track test section in our country. Combined with the engineering examples, the key construction techniques of drilling into the hole by using the long auger drilling rig, controlling the depth of the rock by the current method, and using the drilling machine to insert the reinforced concrete cage after the initial irrigation are given, which can provide reference for the construction of passenger dedicated railway in our country.
