TAKE-DOWN TYPE SURFACE LAYER CASING FOR EARTH DRILL PILE

摘要

PURPOSE:To obtain a surface layer casing to be inserted even for any diameter of earth drill pile by a method in which panels with connectors are connected to both-side edges and the connectors of the panels are held in a shape by fixers. CONSTITUTION:Panels 1b having female connectors 2a and male connectors 2b on its both side edges are connected in a given number, and bolts 10 provided for the connectors 2a are clamped. The angles between the panels are fixed to form a surface layer casing for earth drill pile. The number of the panels 1b is regulated so as to make it applicable to various diameters of earth drill piles. The stock control and transportation thereby can thus be made easier.
