RETAINING SUMP STRUCTURE AND CONSTRUCTION METHOD

摘要

FIELD: hydraulic building, particularly barrages or weirs. ^ SUBSTANCE: structure comprises flexible apron fastened to channel anchors and the first retaining wall installed on the apron with rigid fastening unit. Two additional retaining walls are installed on the apron. The second retaining wall has height exceeding that of other walls and is provided with water discharge orifices arranged in staggered order. Ridge of the third retaining wall is curvilinear. Removable pockets are arranged in front of all retaining walls. Flexible apron parameters may be changed due to shutoff means usage. Method for structure construction involves assembling flexible apron; fixing flexible apron with channel anchors; mounting structure members; arranging channel anchors in the beginning of flexible apron; mounting rigid ties; connecting the ties with channel anchors; securing retaining walls to rigid ties; fixing releasable pockets in front of retaining walls. ^ EFFECT: increased quality of water cleaning of suspended solids, reduced time of structure erection. ^ 2 cl, 3 dwg
