FIELD: construction.
SUBSTANCE: method involves draining shallow-contour marshes before and after the elevating portion of an aerodrome runway. To do this, open manifolds 4 are made from the lowered part of the marsh 1 with the discharge drainage channel 6. Further, the open manifold 4 is connected to the brook 5. In the runway section 3 of the aerodrome, between the open manifolds 4, 7, a closed drainage is constructed, with a slope on both sides of the ramp towards the closed manifold 17, 18, one of which 17 is connected to the brook, and the other 18 - to the open manifold 7. Then the whole stream of water enters the creek 5, in the lower part of which a storage pond 12 of drainage water is built in the side-hill fill. When forming the open manifolds 4, 7, by means of excavating soil from the bank line of the marshes, the construction of a road 9, 10 is started, using the same soil. The closed draining network of the drainage system consists of drains 15, 16 made of polyethylene drainage pipes, for example, with the diameter of 63 mm, laid in channels with a slope towards the closed manifolds 17, 18 and pre-wrapped with geotextile. The entire surface of said geotextile is filled with profiled and compacted granite crushed stone, the surface of which is covered with a layer of geotextile and then the soil is laid, creating conditions for drainage of the closed system. Wherein the drainage pipes are connected at an acute angle to the closed manifold. The proposed technology for the construction of a drainage system of the runway can carry out its long-term operation at all seasons.
EFFECT: drainage, mainly upland, allows to effectively use the features of the structure and properties of the land plot for the construction of aerodrome runways near shallow-contour marshes in general, thereby several times reducing the costs and duration of drainage.
