CONSTRUCTION OF SLOPE SIDE TRENCH AND VARIABLE TRENCH THEREFOR

摘要

PURPOSE:To easily construct slope-side trench by a method in which a slope bottom plate is formed on the bottom slab of lower side trench fixed to the upside of a base, and the lower side of the side plate of an upper trench is fixed to the upper side of the side plate of the lower trench. CONSTITUTION:A base 3 is placed on a trench constructed, and the bottom plates 4 of lower trench 1 are connectedly set on the base 3. A slope bottom slab 5 of concrete is formed with a slope corresponding to a design slope. The coupler 8' of the side plate 6' of an upper trench 2 is fixed to the coupler 8 of the side plate 6 of the trench 1 to form a variable trench 9.
