Abstract

Изобретение относитс к области гидротехники, а именно к устройствам дл защиты откосов земл ных плотин, берегов рек, откосов каналов и др. Цель изобретени - повышение эффективности работы. Крепление откосов земл ных гидротехнических сооружений включает двухр дное покрытие 1, выполненное из полых железобетонных элементов 2, уложенных на откос 3. При этом каждый элемент 2 выполнен в виде пр моугольной плиты с центральной стенкой 5, устроенной посередине плиты 4 параллельно ее длинным сторонам, и двум Г-образными стойками 7, установленными по большим сторонам плиты 4. Кроме того Г-образные стойки имеют консоли 8 длиной, равной 1/4 ширины плиты 4, и направлены навстречу друг другу, на торцовой поверхности одной из консолей 8 выполнен паз, а на другой - соразмерный ему выступ. На стенки 5 двух нижних железобетонных элементов 2 со сдвижкой на половину их длины в пазы Г-образных стоек 7 путем надвижки вход т выступы консолей 8 Г-образных стоек 7 элемента 2 верхнего р да, образу таким образом соединение по типу шпунтового замка. 1 з.п.ф-лы, 6 ил.The invention relates to the field of hydraulic engineering, in particular, to devices for protecting the slopes of earth dams, river banks, canal slopes, etc. The purpose of the invention is to increase operational efficiency. The mounting of the slopes of the ground hydraulic structures includes a two-strand coating 1 made of hollow reinforced concrete elements 2 laid on the slope 3. In this case, each element 2 is made in the form of a rectangular plate with a central wall 5 arranged in the middle of the plate 4 parallel to its long sides, and two L-shaped racks 7 installed on the large sides of the plate 4. In addition, the L-shaped racks have consoles 8 with a length equal to 1/4 the width of the plate 4 and are directed towards each other, on the end surface of one of the consoles 8 groove, and on the other - a proportionate protrusion. On the walls 5 of the two lower reinforced concrete elements 2 shifted by half their length into the grooves of the L-shaped struts 7 by sliding, the projections of the cantilevers 8 of the L-shaped struts 7 of the upper row 2 form, thus forming a tongue-and-groove joint. 1 hp ff, 6 ill.

Claims

Claim

1. The fastening of the slopes of earthen hydraulic structures, including a double-row coating, made of hollow reinforced concrete elements laid on a slope, characterized in that. that, in order to increase work efficiency, each reinforced concrete element is made in the form of a rectangular slab with a central wall arranged in the middle of the slab parallel to its large sides and perpendicular to its surface, and two L-shaped racks installed on the large sides of the slab, while -shaped racks have consoles 1/4 of the width of the plate and are directed towards one another, a groove is made on the end surface of one of the consoles, and a protrusion commensurate with it is made on the other, and the wall is located on the same side of the plate that L-shaped racks, reinforced concrete elements of the lower row are stacked with the possibility of interaction by means of protrusions and grooves with reinforced concrete elements of the upper row, and the elements of both rows are located relative to each other in plan with a shift of half its length.

2. Anchoring according to claim 1, characterized in that the cavities of the reinforced concrete elements of the lower row are filled with stone and the upper one with sand.
