Abstract

Изобретение относитс к строительству каменно-земл ных гидротехнических сооружений из местных материалов. Целью изобретени вл етс сокращение сроков возведени дамбы и уменьщение объема доставки материалов. Способ включает послойную отсыпку упорной призмы, экрана и его пригрузки.Размещение упорной призмы осуществл ют преимущественно в предваритель- но создаваемой траншейной выемке. Перед отсыпкой элементов сооружени производ т планировочные работы. До укладки пригрузки 6 каждого сло вначале отсыпают нижнюю часть 3 экрана, затем возвод т упорную призму 4. После этого на нижней части 3 экрана возвод т верхнюю часть 5. Нижнюю 3 и верхнюю 5 части экрана при этом отсыпают в процессе создани траншейной выемки из разрабатываемых в ней материалов, размеща основание экрана на борту траншейной выемки. Указанна последовательность работ позвол ет возвести дамбу выемочно-погрузочным средством без изменени уровн его установки и переукладки транспортных ком;;,1уникаций. 2 ил. i со 00 4The invention relates to the construction of stone-earth hydraulic structures from local materials. The aim of the invention is to reduce the time it takes to erect a dam and to reduce the amount of material delivered. The method includes layer-by-layer dumping of the stop prism, the screen and its loading. The placement of the stop prism is carried out mainly in the previously created trench recess.

Description

Изобретение относитс к строительству каменно-земл ных гидротехнических сооружений и может быть использовано при строительстве дамб и плотин хвостохранилищ, шла- моотстойников и сооружений дл укладки отходов промывки металлосодержащих песков .The invention relates to the construction of stone-earth hydraulic structures and can be used in the construction of dams and dams of tailing ponds, sludge pits and facilities for laying waste from metal-containing sands.

Цель изобретени - сокращение сроков возведени дамбы и уменьшение объема доставки материалов.The purpose of the invention is to reduce the time to build a dam and reduce the amount of material delivered.

The latter can be performed both in the process of dumping the dam and after its construction.

ПараСпособ возведени дамбы из местных материалов в услови наращивани объединенного хвостохранилища осуществл ют следующим образом.FIG. 1 shows the dam profile; 10 contours of one layer, several layers and in FIG. 2 - dam, plan view. Along the entire front of dumping of the dam. A pair of a method for erecting a dam from local materials under the condition of increasing the joint tailing dump is carried out as follows.

Прокладывают транспортные коммуника- ции, например железнодорожный путь дл доставки из карьера материала, из которого отсыпают упорную призму и приметры выемки выбирают в зависимости от типа примен емого выемочно-погрузочного оборудовани с учетом потребности в материале дл отсыпки экрана.Transport communications are laid, for example, a railway track for delivery of material from a quarry, from which a stop prism is poured and excavation parameters are chosen depending on the type of loading and handling equipment used, taking into account the need for material for screen filling.

load (rock overburden). One method of erecting a dam from local materials is to lay it down hard-wise with this on a 20-prism, screen and load it from the area of the dam of the same tailing dump by prism in the pre-loading means 1, for example, rite. In addition to the created trench excavation and an excavator, they create a trench excavation 2. Carrying out planning works on the poured area of the trench excavation in the trench excavation circuit of the mother, which is different at the same time, is dumped on its board in order scheni terms of WHO-lower part of the screen 3. After this, the removal of the dam and the decrease in volume is filled with a thrust prism 4 with the placement of tanks of materials, prior to the loading of each

the screen layer is first poured out its lower part, then the stop prism, after which the upper part is erected on the lower part of the screen, while the lower and upper parts of the screen are poured out during the construction of the trench excavation from

its predominantly in the pre-created trench excavation and the performance of planning work on the dumped site. Then on the lower part 3 of the screen poured his upper part 5 of the soil taken out of the trench excavation. After this, the loading of the screen b is poured, the loading-out tool 30

move in the direction of progress of work and proceed to the filling of the next layer.

Planning works are carried out on the constructed dam site. The latter can be performed both in the process of dumping the dam and after its construction.

A trench dredging can be created on a full section and narrow, to be expanded when dumping the upper part of the screen, initially takes place in

the contours of one layer, several layers and along the entire front of the embankment of the dam. Paracontours of one layer, several layers and along the whole front of dumping of the dam. The parameters of the excavation are chosen depending on the type of excavation and loading equipment used, taking into account the need for material for filling the screen.
