The radiation well construction of frequency conversion tower-less water supply equipment includes two parts: catchment well construction and radiation pipe construction. The construction of catchment wells is the same as that of large wells. It is worth pointing out that: before the wellbore sinks, the reserved casing on the wellbore needs to be blocked with cork for water supply without tower. After the water-using equipment in the electronic industry sinks to the design elevation, the construction channel is built, the cork is removed and the radiation pipe is constructed.

The construction methods of radiation pipe without tower water supply mainly include manual hammering method, hammer jacking method of frequency conversion water supply equipment, jacking method, water jet method, etc.

Artificial hammering method, usually 12-18 pounds of hammer, frequency conversion desalination equipment water supply equipment, artificial 50-75 mm diameter radiation pipe into the aquifer, hammering one end of the tower-free water supply pipe head should be equipped with a special soft steel cap. This method is often used in the construction of radiation wells in villages and towns.

The hammer jacking method is to hoist the hammer weighing 100 - 150 kg, and the swimming hammer jacks the radiation pipe into the aquifer.

The jacking method of pressure tank is to Jack the radiation pipe without tower into aquifer with 20 - 80 tons oil pressure or screw jack.

The water jet method is to punch the pipe into the aquifer by high pressure water, using zipper crane or other means.
