1300 The use of a concrete ring with a bottom will greatly facilitate the process of installing the well, as it will not be necessary to separately mount the concrete bottom, and place concrete rings on it.

During the construction of the well, a concrete ring with a bottom is first placed in the pit, and concrete rings of the CS are placed on it. This results in an airtight and deaf tank.

Between the elements of the well system THOR are sealing rings. They provide maximum tightness and reliability of the well. The thickened walls of the system make it possible to lay a well up to 20 meters deep.

The protective shell is made of low-pressure polyethylene (PNT) according to GOST 16338-85, designed to ensure durability (not less than 50 years) and waterproofing of sewer tray bottoms and pipes during operation in conditions of highly aggressive medium to concrete (reinforced concrete). PNT is resistant to concentrated hydrochloric, carboxylic and fusible acids, oils, fats, alkalis, salt solutions, resistant to gasoline, low temperatures, ductile and has good impact resistance.
