METHOD OF DRAIN PATH PREPARATION DURING DRAINAGE CONSTRUCTION

摘要

FIELD: agriculture. SUBSTANCE: method provides for choice of the path, determination of stones and boulders location, their bedding depth and parameters and the way of their removal from the path of drain. The stones removal from the drain path is carried out by their deepening in relation to axis of a drainage tube, the size of which is determined by simulating the work of the drainage with the stones and boulders simulation as a waterproof constructions. They draw curves of relationship of drainage stream losses depending on values of stones and boulders deepening and their different parameters. Using the curves they select values of stones and boulders deepening stage by stage. Then, using chosen values of deepening, the scheme of the path of the drainage is made. Deepening of stones and boulders is exercised in accordance with the scheme. EFFECT: method is effective in complex natural conditions drainage systems construction. 2 dwg
