STRUCTURE FOR CONNECTING DRAIN BOARDS

摘要

PURPOSE: A connection method of the ends of drain boards to improve the soft ground is provided to stably maintain the connection strength of drain boards by securing the tensile force of the connection part of the drain boards and to improve the discharge capacity of the drain board by minimizing the reduction of a discharge section. CONSTITUTION: A connection method of the ends of drain boards to improve the soft ground comprises the following steps; A new drain board(12) with a filter(12b) wrapping around a core(12a) and the outer circumference of the core are formed to connect two drain boards inserted into the inside of the soft ground; A connection end(12d) of the core of the new drain board and a filter are bored to have at least one water-feeding hole(12e); The new drain board is inserted into the internal space of a filter(11b) wrapping around the core of the outside of the end of an existing drain board(11); A fastening unit is installed for the connection to fix the ends of both sides of the new drain board and the existing drain board and combined with multiple connection units(20) installed in an oblique line direction.
