A portal frame for rigid landfill anti-seepage construction

Abstract

The utility model belongs to gantry hoisting machinery technical field relates to a kind of for rigid landfill anti-infiltration construction gantry, including the pullable setting with beam mounting seat in balanced support end part, and the movable beam is movably provided at the both ends of fixed beam, and the movable beam is connected with balanced support through beam mounting seat, and the bottom surface of balanced support is detachably provided with anti-deviation auxiliary assembly.The utility model can be adjusted in position on beam mounting seat according to actual demand by movable beam, so as to change the span of gantry, better adapt to the unit cell of rigid landfill of different sizes and the construction scene of diversification, improve the versatility and flexibility of gantry;Anti-deviation auxiliary assembly plays the role of preventing deviation during the movement of gantry, to ensure that gantry moves stably along the predetermined route.
