INTERCONNECTED ELEMENT AND ELEMENT CONSTRUCTION METHOD

PROBLEM TO BE SOLVED: To construct an element in a short period of time by using an interconnected element made of an end part element, left and right steel sheets of the roughly same height and upper and lower steel sheets externally making contact with end part elements on both sides. SOLUTION: End part elements 4, 5 making a clearance between them are connected to each other by an interconnecting element 20 at the time of sequentially constructing the elements in a direction to approach from a plural number of points to protect a roadway, a road, etc., on the ground. This interconnecting element 20 is constituted of the end part elements 4, 5, a pair of steel sheets 21, 22 on both left and right sides or on one side only of the roughly same height and upper and lower steel sheets 23, 24 externally making contact with the end part elements 4, 5 on the both sides. Thereafter, the left or right steel sheet 22 and a coupling of the end part element 5 are engaged with each other by a coupling 25. Consequently, it becomes possible to simultaneously carry out construction at a plural number of points by starting construction from more than two pieces of standard pipes and to reduce construction cost.
