The laying and welding of geomembranes at slope intersections are special cases. Diaphragms within irregularities, such as corners, should be cut into an “inverted trapezoid” with a small width in the upper and a small width in the lower. The toe of the slope at the junction between the channel slope and the base of the site also requires special treatment. During the whole construction process, for the parts repaired after sampling and the places where normal welding construction cannot be adopted, construction rules should be formulated according to the actual situation of the site and local conditions, and special technology should be used for construction.
There are many situations in the construction process of geomembrane that are easily overlooked or difficult to construct. For these situations, once we handle them randomly or don’t pay attention to them during construction, it will bring certain hidden dangers to the whole anti-seepage project. Therefore, geomembrane manufacturers remind us of the construction difficulties of geomembranes in special parts of the site.
1. The laying and welding of geomembranes at slope intersections are special cases. Diaphragms within irregularities, such as corners, should be cut into an “inverted trapezoid” with a small width in the upper and a small width in the lower. The operator should accurately calculate the width-to-height ratio according to the actual situation of the site and the specific size of the slope. If the ratio is not properly grasped, the film surface on the bevel will “bulge” or “hang”.
2.The toe of the slope at the junction between the channel slope and the base of the site also requires special treatment. The construction points in this case are as follows: the membrane on the slope is laid along the slope at a distance of 1.5 from the toe of the slope m， It is then welded to the membrane at the bottom of the field.
3.During the whole construction process, for the parts repaired after sampling and the places where normal welding construction cannot be adopted, construction rules should be formulated according to the actual situation of the site and local conditions, and special technology should be used for construction. For example, ” T Type “and” double T The secondary welding of “type” weld belongs to special position welding.
