Description

Technical Field

[0001] The invention relates to a permanent and temporary combined slag yard drainage structure, belonging to the technical field of soil and water conservation. Background Art

[0002] With the rapid development of the economy, production activities in the fields of mining, construction, and water conservancy are increasing. Slag yards, as important facilities for treating and storing waste, are widely used in these industries. Slag yards are mainly used to store solid wastes such as slag, construction waste, and excavated earth and stone. However, with the increase in the amount of accumulated objects in the slag yard and the complexity of the natural environment in which they are located, the drainage problem of the slag yard has gradually become an important link that cannot be ignored. Especially in rainy seasons or sudden extreme weather conditions, water accumulation in the slag yard will not only affect the stability of the waste slag stacking, but may even cause secondary disasters such as mudslides and slag landslides, which seriously threaten the safety of downstream areas. Therefore, the reasonable design of the slag yard drainage system and the effective water and soil control combined with the long-term use needs of the slag yard have become the core issues in the design and management of modern slag yards.

[0003] Traditional slag dump drainage structures include two types: temporary drainage and permanent drainage. Temporary drainage structures are generally used in the slag dump process, usually using simple drainage ditches, diversion pipes and other facilities, with 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 dump, usually using reinforced concrete structure, complex design, long construction period and high cost. In actual projects, since most of the slag dump process is not compacted, the settlement deformation of the slag dump is large, and the existing permanent drainage structure cannot adapt to the deformation of the slag dump. There are often problems in the connection between temporary drainage and permanent drainage structures, resulting in poor drainage or waste of engineering resources. Therefore, how to achieve an effective combination of temporary drainage and permanent drainage in slag dump construction has become a technical problem that needs to be solved urgently.

[0004] In order to solve the above problems, the present invention proposes a permanent and temporary combined slag dump drainage structure. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a permanent and temporary combined slag dump drainage structure.

[0006] A permanent and temporary combined slag yard drainage structure comprises a slag body, wherein a drainage ditch assembly and an anti-skid step are arranged on the slag body when the slag body is temporarily solidified, wherein the drainage ditch assembly is composed of at least two drainage ditch assembly units, wherein the drainage ditch assembly unit comprises a module body, wherein left and right side walls of the module body are respectively provided with staggered connecting teeth and slide grooves, and front and rear side walls of the module body are respectively provided with staggered pipe grooves and shaft tubes, wherein shaft holes are arranged in the shaft tubes, and two adjacent module bodies are arranged at intervals from each other, wherein the shaft tube on one module body is engaged with the pipe groove on another module body, and the two modules are connected by a multi-hole connecting pipe, wherein the connecting teeth on one module body are engaged with the slide groove on another module body; During permanent consolidation, a steel mesh layer is laid on the drainage ditch assembly, and a concrete surface layer is poured on the steel mesh layer.

[0007] Furthermore, a first gravel cushion layer, a geomembrane layer and a second gravel cushion layer are laid in sequence from bottom to top between the drainage ditch assembly unit and the slag body.

[0008] Furthermore, the anti-skid sill is arranged at intervals along the length direction of the drainage ditch assembly, and one is arranged at the starting point and the end point. The anti-skid sill is composed of a bottom trapezoidal sill and backfill concrete cast in one piece. The cross-section of the bottom trapezoidal sill is a right-angled trapezoid and is embedded in the slag body.

[0009] Furthermore, the anti-slip step is arranged at the intersection of the drainage ditch assembly units of the ditch assembly body.

[0010] Furthermore, the cross-section of the slide groove is trapezoidal, and the width of the slide groove gradually increases inwardly, and the shape of the connecting tooth is adapted to the shape of the slide groove.

[0011] Furthermore, the shaft tube is a cylinder, the cross-section of the tube groove is an arc surface, the cylinder is embedded in the arc surface, the shaft tube and the shaft hole are arranged concentrically with the tube groove, and the tube groove and the shaft tube have the same length.

[0012] Furthermore, a full-length steel bar is arranged in the porous connecting pipe, and backfill slurry is poured into it.

[0013] Furthermore, a normal cast-in-place section is arranged at the rear non-slag section of the drainage ditch assembly.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The adjacent modular drainage ditch assembly units are connected by bearing hinges composed of pipe grooves, shaft pipes, slot holes and porous connecting pipes to form a typical cross-section of the drainage ditch. They are assembled and extended along the water flow direction through the chute and connecting teeth to form a temporary drainage ditch for the slag yard. The construction speed is fast and can be flexibly adjusted at different construction stages to adapt to the settlement of the slag yard. In addition, they are designed according to the size of the permanent drainage ditch and have strong temporary drainage capacity during construction. (2) After the temporary drainage ditch formed by assembly has settled steadily in the slag dump, full-length steel bars are inserted into the porous connecting pipes and backfilled with slurry. A steel mesh is laid on the surface of the temporary drainage ditch and a concrete surface layer is cast in situ to enhance the integrity and durability of the structure. The drainage system can be directly transitioned to permanent drainage facilities, reducing secondary construction and resource waste; (3) The construction method is simple and economical, and is suitable for slag dump environments with various geological and climatic conditions. The design and application of the drainage structure of this scheme can significantly improve the safety and environmental protection level of the slag dump. BRIEF DESCRIPTION OF THE DRAWINGS
