Slag stacking structure and slag stacking method

Abstract

The invention discloses a slag stacking structure and a slag stacking method. The slag stacking structure comprises gravel protecting feet located below the downstream water level and gravel protecting slope located above the downstream water level, the gravel protecting foot is formed by filling crushed stone with the particle size larger than phi in stone slag, and the rest of gravel in the stone slag forms a gravel slope; a reinforced concrete plate is laid on the surface of the gravel protection slope, and the gravel protection foot is arranged on the geotechnical cloth; and a drainage blind ditch is arranged between the gravel slope protection and the reinforced concrete plate; the drainage blind ditch extends into the gravel slope protection slope, and geotechnical cloth is wrapped outside the drainage blind ditch. The technical effect of the slag stacking structure and the slag stacking method is as follows that, the slag yard is arranged on a downstream river channel, so that the cost such as land collection and immigration of a slag field and a road connected with the slag yard can be reduced; adjacent engineering excavation area and reduces waste slag transportation distance; simple drainage and protection measures are implemented, and the protection amount of the slag field engineering is reduced; and by backfilling the stone slag on the downstream river bank, the slope surface is trimmed, so that the safety performance is improved.

Description

Technical field [0001] The invention belongs to the technical field of hydropower and water conservancy engineering, and particularly relates to a slag piling structure and a slag piling method. Background technique [0002] In the process of constructing hydraulic dams, a large amount of spoil is often produced. These spoils need areas to be absorbed. At this time, some natural creeks are usually selected as slag dumps, and some creeks are far away from the construction area, which requires additional costs for land acquisition and resettlement, environmental protection, and long-distance transportation. Summary of the invention [0003] The purpose of the present invention is to provide a slag piling structure and a slag piling method in view of the above-mentioned deficiencies of the prior art. The slag piling is carried out on the open river bed downstream of the dam site, which can reduce the cost of slag piling. [0004] In order to solve the above technical problems, the te...
