Zusammenfassung:PURPOSE:To avoid the occurrence of escaping phenomenon or avoidance of hard concrete by excavator by a method in which a wide aperture is formed between preceding elements, and excavation is made under the guidance of the wide aperture for the excavator. CONSTITUTION:A spacer box 5 is set on at least upper end of an excavated ground in the direction of joining an excavated pit 1 for forming preceding element and concrete 4 is placed to form the preceding element. After the concrete hardens, the spacer box 5 is removed away to form a wide interval with a great end spacing between the preceding elements. Under the guidance of the wide interval for excavator, excavation is made between the two preceding elements.
