Description

(54) ПЛОТИНА ИЗ МЕСТНЫХ МАТЕРИАЛОВ(54) DAM OF LOCAL MATERIALS

Изобретение относитс к строительству гидротехнических сооружений и может быть использовано при возведении подпорных сооружений вThe invention relates to the construction of hydraulic structures and can be used in the construction of retaining structures in

виде подпорйлх дамб или плотин изform of dammed dams or dams out

местных материалов.local materials.

Известно подпорное сооружение в виде каменнонабросной плотины, выполненной с гребнем в виде бетонной арки, п ты которой оперты на береговые склоны, что обеспечивает устойчивость плотины при некотором сокращении объема работ Cl. . Недостатком этой плотины вл етс различна жесткость тела плотины и бетонной арки на гребне, вследствие чего не возможно производить измерени деформаций пригребневой зоны плотиМы и своевременно выполнить ремонтн|ф работы.A retaining structure is known in the form of a stone-climbing dam, made with a crest in the form of a concrete arch, whose feet are supported on coastal slopes, which ensures the stability of the dam with a certain reduction in the amount of work Cl. . The disadvantage of this dam is the different stiffness of the body of the dam and the concrete arch on the ridge, as a result of which it is not possible to measure the deformations of the flank zone of the flesh and perform repair work in a timely manner.

Известна также плотина из местных материалов, включающа противофильтрационное дро и железобетонную галерею , размещенную на гребне дра 2.Also known is a dam of local materials, including an impermeable draw and a reinforced concrete gallery, located on the ridge of the core 2.

Однако данное подпорное сооружение также не приспособлено к ведению натурных наблюдений, к измерению деформаций пригребневой зоны плотины и к производству ремонтных работ ввиду замкнутости контура железобетонной галереи и наличи на гребне дра анкерной плиты.However, this retaining structure is also not adapted for conducting field observations, for measuring the deformations of the dam's ridge zone, and for carrying out repair work due to the closed contour of the reinforced concrete gallery and the presence of an anchor plate on the ridge of the core.

Цель изобретени - повышение надежности плотины за счет удобства ведени визуального контрол и восстановительно-усилительных работ деформируемых участков дра.The purpose of the invention is to increase the reliability of the dam due to the convenience of maintaining visual control and redressing work of deformed parts of the core.

Указанна цель достигаетс тем, что железобетонна галере выполнена This goal is achieved by the fact that reinforced concrete gallery is made

10 в виде свода с выносными опорами п т, между которьоми размещен участок свободной поверхности гребн дра, который снабжен измерительной сеткой, нанесенной на слой прозрачного легко15 деформируемого влагоудерживающего материала, например латекса, а галере снабжена верхними и боковыми люками.10 in the form of a roof with outriggers pt between which a free surface of the ridge core is placed, which is provided with a measuring grid applied onto a layer of transparent, easily deformable water-retaining material, such as latex, and the gallery is provided with upper and side hatches.

На фиг. 1 изображено подпорное FIG. 1 depicts a retaining

20 сооружение, поперечный разрез-, на фиг. 2 - разрез А-А на фиг. Ij ,на фиг. 3 - разрез Б-Б на фиг. 1.20, a cross-section, in FIG. 2 shows section A-A in FIG. Ij, in FIG. 3 shows a section BB in FIG. one.

На гребне 1 дра 2 подпорного со25 оружени размещена надстройка, выполненна из открытых снизу секционных элементов 3 с выносными опорами 4.On the crest of 1 core 2 of the retaining arm is a superstructure, made of sectional elements 3 open at the bottom with outriggers 4.

Claims

Sectional elements are installed from side to side of the canyon and equipped with 30 top 5 and side 6 hatches. The ridge 1 of the core 2 within its open surface is covered with a layer 7 of easily deformable material on which the coordinate grid 8 is applied, for example, rectangular. During operation of the facility, due to consolidation of core 2, it deforms with ridge 1 and layer 7 of easily deformable material, and the coordinate grid 8 is distorted accordingly. Distortion of the coordinate grid is systematically monitored both visually and using measuring instruments. According to the magnitude of the displacements of the nodal points 9 and the distortions of the right angles of the grid 8, the deformations in the core are judged. When the maximum permissible deformations are reached or when a fracture occurs in the fracture, the necessary reinforcement works are performed. In the process of preparing the restoration work, the delivery of personnel, mechanisms and materials to the open surface of the ridge is carried out through the top 5 and side 6 hatches. Claims of the invention: A dam of local materials, including an impervious drawball and a reinforced concrete gallery located on the ridge of the core, characterized in that, in order to increase the reliability of the dam due to the convenience of maintaining visual inspection and redressing work of deformed sections of the core, of the roof with outriggers pt, between which there is a section of the free surface of the ridge, which is equipped with a measuring grid applied onto a layer of transparent lightweight A compatible water-holding material, such as latex, and the gallery is equipped with upper and side hatches.
