Method for building isolating walls especially for securing underground construction by inserting prefabricated concrete sections and sealing with a filler

摘要

A cost effective method for building isolating walls, especially for underground structures such as cellars, has a slit trench (120 cur by an excavator and filled with a water suspension to prevent collapse. Prefabricated concrete sections are inserted and secured. The suspension is removed and adding a filler seals the construction.
