我队根据钻探施工中某些特定工艺的要求,设计制造了四翼水压扩孔器和两翼水压扩孔器,用于水文地质孔施工曾取得局部扩孔水泥止水的成功。根据其功能,应用它处理某些孔内事故,将会取得优于其它工具的效果。预计在适当的条件下用于水源井施工,可取得保证质量、提高效率、降低材料消耗的效果。 Our team designed and manufactured the four-wing hydraulic reamer and the two-wing hydraulic reamer according to the requirements of some specific processes in drilling construction. The hydro-reaming hole has been successfully used to stop the local reaming of the cement. Depending on its function, applying it to handle some hole accidents will yield better results than other tools. It is estimated that under suitable conditions, it can be used for water source well construction to obtain the effect of ensuring the quality, improving the efficiency and reducing the material consumption.
