FIELD: construction.SUBSTANCE: structure in the form of a prism with a polygonal discharge and bottom slope is assembled from spacer tubes along the entire coast of the river. Spacer tubes are fixed by yokes around the transverse reinforcement to produce nodes. Waterproof material is laid under the frame of the structure on the prepared soil of the base. At the discharge side there is waterproof cloth laid on the polygonal slope and fixed to produce extended blanket. Length of the waterproof section L will be L?CH, where L - length of extended underground contour, at which there are no filtration deformations; C - Bligh's coefficient - value reverse to gradient; H - existing head. The frame of the structure is fixed to the soil of the base by anchors. Diameters of spacer tubes are 30-100 mm. The structure has high resistance of the structure to shift, reduces filtration, increases length of filtration track and prevents possible filtration deformations.EFFECT: increased durability and provides for possibility to use an anti-flood structure many times.3 cl, 3 dwg |
