Abstract: PURPOSE: A nail with an excellent gripping force and excellent workability and a construction method thereof is provided to improve the gripping force at an end portion due to the blowing portion of an expansion portion during nail construction. CONSTITUTION: A nail with an excellent gripping force comprises a support portion(100) and a head portion. The support portion is separated a long support portion and a front support portion and is connected with a coupler. The head portion comprises a fixed body(210), an expansion portion(230), a front case(240), and a fixture(250). The fixed body comprises an outer taper and an inner taper. The expansion portion is expanded in order to prevent the pullout of the nail by a fixed wedge inserted around. The front support portion is fixed on the fixed body and includes a stopper(241) protruded to an internal space. The fixture is fixed on one side of the support portion and includes a female screw penetrated by a bolt in order to insert a bolt.

Abstract: PURPOSE: A construction method of a front block type reinforced earth retaining wall with improved pull-out resistance using geogrid is provided to prevent bulging by increasing the friction with backfilling soil. CONSTITUTION: A construction method of a front block type reinforced earth retaining wall with improved pull-out resistance using geogrid is as follows. The ground of a construction site is excavated and arranged. Foundation is formed in the arranged ground. Front blocks(10) are built on the top of the foundation. Backfilling aggregate(20) is filled in the rear of the front blocks. Backfilling soil(30) is filled in the rear of the backfilling aggregate. Geogrid(100) is installed on the backfilling soil. Other front blocks are built on the top of the front blocks. Backfilling aggregate is filled in the rear of the front blocks. Backfilling soil is filled in the rear of the backfilling aggregate. Geogrid(100') coupled with a friction plate is connected to the front blocks.
