Well drilling construction "Donut Drill Method" (Old well regeneration)

Many achievements! A groundbreaking method that completely revitalizes the structure of old wells as good as new. It allows for the use of existing land and facilities, contributing to cost reduction!

Using a self-developed donut drill machine, we excavate the outer circumference of old wells in a donut shape down to the bottom of the well, extracting all structural components from the screen and casing pipe to the filling gravel, thereby regenerating the well structure. Our method, utilizing the latest technology in materials and finishing techniques, excels in water lifting efficiency and provides high-quality wells that do not produce sand. 【Benefits】 1. Unlike conventional double casing construction or renovation work, it fundamentally resolves various troubles. 2. It transforms into a high-quality well that does not produce sand. * We conduct sand volume measurements, with a handover condition of 5 mg/L or less, but the actual sand volume is below 1 mg/L. 3. There is no need to acquire new land. 4. Existing water supply pipes and electrical equipment can be reused, helping to reduce overall construction costs. The "Donut Drill Method" is widely adopted in public facilities and private factories across the country.
