Description

TECHNICAL FIELD

[0001] The utility model relates to a permanent and temporary combined slag field drainage structure and belongs to the technical field of water and soil conservation. BACKGROUND

[0002] With the rapid development of economy, the production activities in the fields of mine, building and water conservancy are increasing, and the slag field as an important facility for treating and storing waste is widely used in these industries. The slag field is mainly used for stacking solid waste such as slag, construction waste and excavated earth and stone materials. However, with the increase of the volume of the stacked objects in the slag field and the complexity of the natural environment, the drainage problem of the slag field has gradually become an important part that cannot be ignored. Especially in the rainy season or in the case of sudden extreme weather, the water accumulation in the slag field not only affects the stability of the waste slag stacking, but also may cause secondary disasters such as mudslides and slag field landslides, which seriously threatens the safety of the downstream area. Therefore, reasonable design of the slag field drainage system and effective control of water and soil in combination with the long-term use requirements of the slag field have become the core problem in the design and management of modern slag fields.

[0003] The traditional slag field drainage structure includes two types of temporary drainage and permanent drainage. The temporary drainage structure is generally used in the process of stacking slag in the slag field, and usually adopts simple drainage ditches, diversion pipes and other facilities, which has the characteristics of low cost and convenient construction, but the long-term use effect is poor, the drainage capacity is limited, and it is difficult to cope with large-scale precipitation. The permanent drainage structure is mainly used in the long-term operation stage of the slag field, and usually adopts reinforced concrete structure, which has complex design, long construction period and high cost. In actual engineering, since the stacking process is not rolled, the settlement deformation of the slag field is large, the existing permanent drainage structure cannot adapt to the deformation of the slag field, and the connection between the temporary drainage and the permanent drainage structure often has problems, which leads to poor drainage or waste of engineering resources. Therefore, how to realize the effective combination of temporary drainage and permanent drainage in the construction of the slag field has become a technical problem to be solved at present.
