Embodiment Construction
[0017] Such as figure 1 , figure 2 As shown, the slag retaining structure of this embodiment is arranged on the periphery of the soil and gravel slag field 8, and it includes a drainage cushion 2 laid on the strong weathered layer on the ground, and a slag retaining body 4 with a trapezoidal cross-section is arranged on the drainage cushion 2. The slag retaining body is formed by layered rolling of the discarded material 3 (requiring that its stone volume is not less than 60%) in the earth and gravel slag field. The upstream slope of the slag retaining body 4 is covered with a gravel filter layer 5, and the thickness of the filter layer is generally not less than 50 cm. In order to improve the appearance of the slag retaining body to utilize environmental protection, a planting groove 6 is also arranged at the slope foot downstream of the slag retaining body, and plants 7 (generally climbing plants) are planted in the groove.
[0018] In addition, in order to ensure the str...

The invention relates to a debris retaining structure for debris fields and a construction method thereof. The invention aims to provide a debris retaining structure for debris fields and a construction method of the structure. The debris retaining structure has the advantages of convenient material taking, investment saving and favorable landscape effect. The invention has the technical scheme that the debris retaining structure is arranged on the periphery of the debris field. The invention is characterized in that the debris retaining structure comprises a drainage blanket laid on the ground strong-weathered layer, wherein a debris retaining body, which is obtained by milling waste material with the cubic meter of stone of not less than 60% from the debris field in a layered mode; the cross section of the debris retaining structure is trapezoidal; an inverted filter, of which the thickness is not less than 50cm, is laid on the upstream slope of the debris retaining body; and the downstream toe of the debris retaining body is provided with a planting groove in which plants are grown. The invention is suitable for retaining waste debris in large-size and medium-size debris fieldsin hydraulic and hydroelectric engineering.
Description
technical field [0001] The invention relates to a slag retaining structure for a soil and rock slag field and a construction method thereof, which is suitable for retaining waste slag in a large and medium-sized water conservancy and hydroelectric project earth and stone slag field. Background technique [0002] A large amount of earth and gravel slag is generated during the construction of development and construction projects, and retaining walls (dry masonry, mortar masonry or concrete), reinforced gabions, etc. are usually set up below the slag yard to block and spoil the slag. Not only does it require high materials and requires a large investment, but also because the appearance of the retaining wall or steel gabion is in contrast to the surrounding landscape, it is not conducive to environmental protection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a slag retaining structure for a soil and rock slag ...
