[0003] In water conservancy and hydropower projects, during the construction process, a large amount of waste slag will be generated, and it is necessary to set up a waste dump to centrally treat the project waste slag. The selection of the waste dump needs to consider aspects such as topographic and geological conditions, hydrological conditions, traffic conditions, environmental protection and soil and water conservation requirements. The layout of the waste dump is often relatively independent.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0007] A shape and slag stacking structure of a waste dump close to a material yard includes a waste dump and a material yard that are close to each other. A reserved rock embankment is arranged between the waste dump and the material yard, and the waste dump top elevation of the waste dump is higher than the final mining platform of the material yard; the waste slag of the waste dump includes permanent slag and temporary slag. The temporary slag is located above the permanent slag, and the temporary slag is transported to the final mining platform of the material yard for stacking in the later stage of construction.

[0008] Further, the waste dump is provided with a retaining structure and a drainage structure at the toe of the slope and on the slope surface.

[0009] Further, the toe of the slope of the waste dump is blocked by a concrete retaining wall, and the slope surface of the waste dump is protected by shotcrete; the drainage structure adopts a number of reserved drainage holes.

[0010] Further, the temporary slag is stacked from both sides upwards, and a 3m-wide platform is reserved at the top elevation of the temporary slag.

[0011] Further, the top elevation of the reserved rock embankment is the same as the top elevation of the permanent slag.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The utility model relates to a slag dump shape and slag stacking structure close to a material yard. By reasonably distinguishing the permanent slag stacking shape and the temporary slag stacking shape, the slag dump and the material yard are combined and arranged by using a reserved rock bank, which is efficient and economical, reduces the number of temporary facilities at the construction site, reduces the construction difficulty, optimizes the site layout, reduces the floor area, and improves the land utilization rate.

Detailed Description of the Embodiment

[0018] The following further describes the embodiments of the utility model in detail with reference to the drawings.

[0019] As Figure 1 , 2 shown, a slag dump shape and slag stacking structure close to a material yard includes a closely adjacent slag dump 1 and a material yard 3, and the construction of the slag dump 1 and the material yard 3 restricts each other. A reserved rock bank 5 is arranged between the slag dump 1 and the material yard 3, and the top elevation of the slag in the slag dump 1 is higher than the final mining platform 4 of the material yard; the slag in the slag dump 1 includes a permanent slag stacking 6 and a temporary slag stacking 2, and the slope ratio of the slag stacking in the slag dump 1 meets the requirements of stability calculation. The temporary slag stacking 2 is located above the permanent slag stacking 6. As Figure 3 shown, the temporary slag stacking 2 is transported to the final mining platform 4 of the material yard for stacking in the later stage of construction. The top elevation of the reserved rock bank 5 is the same as the top elevation of the permanent slag stacking 6, and the reserved rock bank 5 meets the bearing capacity requirements of the permanent slag stacking 6 and the construction requirements of the material yard 3. Further, the top elevation, top width and slope ratio of the reserved rock bank 5 need to be determined comprehensively according to the rock conditions and the amount of temporary slag.

[0020] The slag dump 1 is provided with a retaining structure and a drainage structure at the slope toe and the slope surface. The slope toe of the slag dump 1 is blocked by a concrete retaining wall, that is, the slope toe retaining wall 7 of the slag dump, and the slope surface of the slag dump 1 is protected by shotcrete; the drainage structure adopts a number of reserved drainage holes.

[0021] The temporary slag stacking 2 is stacked from both sides upwards, and a 3m-wide top platform 8 of the temporary slag stacking is reserved at the top elevation of the temporary slag stacking 2.

[0022] The construction process of the present utility model is as follows: Before the slag dump 1 starts to stack slag, the original terrain is cleared to the bedrock, and then the construction of the toe wall 7 of the slag dump is carried out; after the construction of the toe wall 7 of the slag dump is completed, the permanent slag stack 6 can be stacked, and the construction of the slope protection and drainage structure is carried out synchronously during the construction of the permanent slag stack 6; according to the engineering geological conditions and the calculation of earth-rock balance, the elevation of the slag stack top of the slag dump 1 is higher than the elevation of the final mining platform 4 of the material yard, so a reserved rock ridge 5 is arranged to ensure the normal construction of the slag dump 1 and the material yard 3, and the top elevation of the reserved rock ridge 5 is the elevation of the slag stack top of the permanent slag stack 6.

[0023] Embodiment 1

[0024] Through the dynamic calculation of earth-rock balance and rock conditions, the height of the reserved rock ridge 5 is set to 10m, the top width is 5m, and the excavation slope ratio of the reserved rock ridge 5 is 1:0.75. After the construction of the reserved rock ridge 5 is completed, the construction of the material yard 3 and the temporary slag stack 2 can continue. After the material yard 3 is excavated to the final mining platform 4 of the material yard, the temporary slag stack 2 can be transferred onto the final mining platform 4 of the material yard.

[0025] In this example, to meet the stability requirements and construction requirements of the temporary slag stack 2, the slope ratios on both sides of the temporary slag stack 2 are both 1:2, and the width of the top platform 8 of the temporary slag stack is 3m.

[0026] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the concept of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as within the protection scope of the present utility model.
