Loose rock dam are using rockfill as support, a kind of dam type using materials such as soil, concrete, bituminous concretes as antiseepage body and water-retaining structure.Rock can utilize local material directly to build a dam because of it, and has the advantages such as the impact of climate condition is little, the duration is short, and becomes the dam type being most widely used in hydropower station at present construction.But in some engineerings, owing to affected by natural geological conditions, local material, taking mud stone as main, if original mud stone is given up, will directly cause engineering quantity to increase, also need separately to seek the dam material that intensity is higher simultaneously, material is bought and is transported and also will cause cost of investment greatly to increase, and in addition, has also increased the scale of slag field, thereby increase the harmful effect that Engineering causes, the economy of this kind of dam type is had a greatly reduced quality.
Therefore, how to overcome the shortcoming that mud stone intensity is low, meet water easy disintegrating, or avoid its shortcoming, be arranged in the reasonable position of dam body and taked suitable reliable safeguard procedures, realization is gathered materials on the spot, to make full use of local material, reduce damming works amount and cost of investment, become the problem that Hydropower Station Construction technician solves of being badly in need of.
Utility model content
In order to address the above problem, the utility model provides a kind of rock structure of utilizing mud stone dam material, has reached and has improved engineering efficiency, reduces engineering quantity and cost of investment and reduce the beneficial effect of environment pollution.
The utility model is achieved by following technical solution.
A kind of rock that utilizes mud stone dam material, its upstream side is followed successively by transition zone from inside to outside, bed course and upstream slope-protection, described upstream apron layer and upstream rock ballast loading layer are positioned at upstream side hypomere, described special bed course is positioned at bed course end, its downstream is downstream protection slope, dam body rockfill area comprises draining rockfill area, mud stone rockfill area and hard rock rockfill area, described draining rockfill area one side is positioned under transition zone, mud stone rockfill area is divided into upper and lower two parts by one side level, lower part mud stone rockfill area is positioned on the dam foundation, upper part mud stone rockfill area is positioned at the dry section more than level of tail water, top and bottom and downstream side in upper part mud stone rockfill area are equipped with loaded filter.
More than described draining rockfill area is positioned at the level of tail water.
Described hard rock rockfill area is positioned at dam crest and accounts for 1/3 of height of dam.
The beneficial effects of the utility model are:
A kind of rock that utilizes mud stone dam material described in the utility model, by gathering materials on the spot, dam site and near mud stone material thereof are arranged near the dry section dam foundation and more than the level of tail water, by draining rockfill area and loaded filter, mud stone rockfill area is protected simultaneously, and be provided with effective draining rockfill area, reduce the possibility of dam body generation seepage failure, guaranteed that safety of dam body is reliable;
Owing to directly having utilized the mud stone material of the dam foundation and near excavation thereof, well solve the cubic metre of earth and stone equilibrium problem of engineering, reduce construction investment, and greatly reduced the scale of slag field, reduce the harmful effect of engineering to ecological environment;
In addition, because mud stone has the character that intensity is lower, early stage be easy to carry out compacting in construction, reduced after having constructed and caused dam deformation and make panel produce damaged situation to occur by mud stone.
