Connection structure of before and after pile connection for two rows pile construction

PURPOSE: A connection structure of front row and rear row pile connecting members in a two row self-standing type earth retaining method is provided to reduce construction periods, construction costs, and earth pressure and be applied to a place in which available space does not exist. CONSTITUTION: A connection structure of front row and rear row pile connecting members in a two row self-standing type earth retaining method connects the front row pile connecting member and the rear row pile connecting member while a front row pile (200) or a rear row pile (100) is embedded in order to be inclined. The front row and rear row pile connecting members include a round rod shape and includes a connecting member mounting unit (20), a furring strip (400), and a plate for compression (50). The plate for compression compresses and connects the furring strip to the connecting member mounting unit.
