A method of construction of subsurface drainage and filtration-proof structures is carried out in cycles. Each cycle includes sequential implementation of following operations: digging trench with bays by means of earth-moving executive device, filling of cavity of trench with solution for stabilization of walls of trench, control of maximal deepening of executive device to trench, working motion of basic machine to length of one bay, working motion of cassette with laying from cavity of cassette to cavity of trench of drainage and filtration-proof element by length of one bay. In process of digging trench one provides additional filling of its cavity with underground waters, that for digging of trench is started from project marks of trench with higher levels of underground waters with its implementation in direction towards marks with lower levels of underground waters. |
