Lightweight earth laid and earth laid creation construction method

摘要

PURPOSE:To prevent settlement and falling-in of banking by forming a lightweight solid type piece made of waste material and having fine foams into gravel, and distributing them in the filling material under the mutually engaged condition to form an integral banking body. CONSTITUTION:Water and the foaming material are agitated for mixture and distribution, and is added to the cement paste, and is agitated for mixture again to form a piece made of the foaming paste as the base material. This piece is formed into a random shape that a projecting part and a recessed part thereof are engaged with each other. This piece is mixed with the filling material made of natural soil by a mixer or the like to be buried in the filling material. The banking main body 3 prepared as the base material is carried into the soft ground 2 of the field by a damp truck or the like, and the banking main body 3 is formed by back hoe. Furthermore, the surface of the banking main body 3 is covered with the presser material 5 and a covering layer 4 made of the natural soil is laid thereon to unify the banking 1 strongly.
