本机适用于直径1.5m、扩底部直径2.6m的大口径扩底桩施工,钻头有大、中、小三种型号,扩大了机械的使用范围。特点:1.用一台钻机可完成包括扩底在内的全部钻削施工,机动性好、施工效率高;2.由于直孔变细,减少了钻削土及浇溉砼的量,故能缩短工期、节省工程费用;3.扩底钻头上装有扩大量检测器,依靠钻机操作台上的指示器,可以方便准确地进行施工;4.依靠钻削深度计,可准确地扩
This machine is suitable for large-diameter pedestal pile construction with a diameter of 1.5m and a diameter of 2.6m at the bottom of the base. The drill has three models: large, medium and small, which expands the scope of use of the machine. Features: 1. A drilling rig can be used to complete all the drilling construction, including the expansion of the bottom, the mobility is good, the construction efficiency is high; 2. Because the straight hole becomes fine, reducing the amount of drilling soil and pouring hoe, so Can shorten the construction period and save the project cost; 3. The enlarged drill bit is equipped with an enlarged quantity detector, and the indicator on the drill rig operating table can be used for convenient and accurate construction; 4. It can accurately expand with the drilling depth gauge.
