处于沪汉蓉线上的合肥火车南站工程目前正在紧张施工,该工程约有2 600根钻孔桩、263个承台。施工作业段路较为集中,钻机现场施工分布密度较大,对各大品牌钻机的成孔效率及钻机质量是一个严峻考验。并且工程前期正值南方雨季,对工程进度造成较大影响,为保证施工进度,确保工程按期完工,该工程承建方要求各施工单位加快施工速度,对现场施工较慢及成孔质量较差的旋挖钻机进行清场。
The Hefei South Railway Station project, which is located on the Shanghai-Hailong Line, is currently under construction. There are about 2,600 bored piles and 263 caps in the project. The construction work section is more concentrated, and the distribution density of the drilling rig on site is relatively large, which is a severe test on the hole forming efficiency and rig quality of major brands of drilling rigs. In the early stage of the project, the rainy season in the south has a great impact on the progress of the project. To ensure the progress of the construction and ensure the completion of the project on schedule, the contractor of the project requires the construction units to speed up construction, slow construction on site and poor quality of the holes Rotary drilling rig clearance.
