Abstract

PURPOSE: To promote safety in the construction site where ventilation is not satisfactory for a construction work to build a vibration-proof wall by means of injecting and foaming polyurethane foaming solutions into the ground, by making use of a specific type of hard polyurethane foaming liquid for the mentioned purpose.
CONSTITUTION: When a vibration-proof wall 7 is to be built between a concrete structure 1 and an underground wall 2 of a building, a form 4 is installed on the ground 3 between the concrete structure 1 and the underground wall 2 of the building, and a waterproof sheet 5 is applied to the inside of the form 4. A vibration- proof wall 7 made of polyurethane foam is build by injecting and foaming hard polyurethane foaming solutions from a foaming machine 6 to a gap between the waterproof sheet 5 and the concrete structure 1. At the time the solutions to be used are to consist of diphenylmethane diisocyanate or polyisocianate component with this as main ingredient, polyole containing nitrogen atom or polyole component containing this and foaming agent.
