Description
Technical field
The present invention relates to administering method field, metallurgical slag stockyard, especially a kind of metallurgical slag stockyard processing method.
Background technology
Smelting iron and steel is kept away and unavoidably will be produced a large amount of debris dumps and abandon, and along with the raising of environmental requirement, slag field is administered unavoidable.For discarded metallurgical stockyard, very easily cause environment pollution, as airborne dust, water pollutions etc., comparatively large on surrounding enviroment impact, have a strong impact on local environmental development.Simultaneously in order to steel mill produces continually and steadily, be necessary to solve the disposal of discarded object and the contradiction of environmental protection, therefore need to administer slag field side slope.
Summary of the invention
Technical problem to be solved by this invention is to provide one and effectively processes smelting iron and steel waste residue, thus reduces the metallurgical slag stockyard processing method of the secondary pollution of waste residue.
The technical solution adopted for the present invention to solve the technical problems is: metallurgical slag stockyard processing method, comprises the following steps:
A, build cast-in-place basis and the barricade that is ground with cast-in-place basis in collection site;
B, metallurgical slag filled as filler layering and is compacted in region that barricade surrounds, and being provided with reinforced bar net between every layer of metallurgical slag;
C, form slope body by above-mentioned metallurgical slag and reinforced bar net, the domatic of described slope body is provided with rubble loaded filter;
The surface of d, above-mentioned rubble loaded filter is provided with green layer.
Further, described cast-in-place basis and domatic intersection are provided with gutter, and the groove that the current on described domatic surface converge to gutter is discharged.
Further, the end face of slope body is provided with cement stabilizing layer.
Further, described cement stabilizing layer is provided with planting soil.
Further, described green layer is made up of planting soil and the grass-seed planted on described planting soil.
Further, degree of compaction >=93% of the metallurgical slag in step b near reinforced bar net.
Further, the domatic abrupt slope ratio of slope of step c is 1:0.5 ~ 0.75.
The invention has the beneficial effects as follows: be fill raw material with metallurgical slag, metallurgical slag is filled in cast-in-place basis and with in the barricade that is ground of cast-in-place basis, namely achieves the concentrated stacking to metallurgical slag.In addition, metallurgical slag layering is filled, and reinforced bar net is set between every layer of metallurgical slag, the soundness of slope body can be improved greatly.Last, firm be that the domatic of slope body of filling raw material arranges rubble loaded filter with metallurgical slag, and green layer is set on described rubble loaded filter, the domatic of slope body well can be maintained, allow domaticly withstanding rainwash.The present invention is particularly useful for adopting in the improvement in the metallurgical slag stockyard of steel mill.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Be labeled as in figure: slope body 1, green layer 11, rubble loaded filter 12, reinforced bar net 13, metallurgical slag 14, domatic 15, cast-in-place basic 2, gutter 3, groove 31, cement stabilizing layer 4, planting soil 41.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Metallurgical slag stockyard processing method, comprises the following steps:
A, build cast-in-place basic 2 and the barricade that is ground with cast-in-place basic 2 in collection site;
B, metallurgical slag 14 filled as filler layering and is compacted in region that barricade surrounds, and being provided with reinforced bar net 13 between every layer of metallurgical slag 14;
C, form slope body 1 by above-mentioned metallurgical slag 14 and reinforced bar net 13, domatic 15 of described slope body 1 is provided with rubble loaded filter 12;
The surface of d, above-mentioned rubble loaded filter 12 is provided with green layer 11.
Along with the increasing of energy-saving and emission-reduction dynamics, pollutant control becomes when the important and difficult task of last item, for adapting to Environmental Protection Situation demand for development, around smelting system waste residue link, strengthen the introduction of environmental protection key technology, digestion and autonomous innovation, constantly stride forward to innoxious governance, for realizing the backing that sustainable development provides strong.Design of the present invention achieves the airborne dust, the water pollutions that prevent metallurgical slag by administering metallurgical slag.By cast-in-place basic 2 and the barricade that is ground with cast-in-place basic 2, for inserts metallurgical slag provides solid stable parking space, then, metallurgical slag 14 is filled as filler layering and is compacted in region that barricade surrounds, and be provided with reinforced bar net 13 between every layer of metallurgical slag 14, firm slope body 1 structure can be built.Last, domatic 15 of slope body 1 is provided with rubble loaded filter 12, and the surface of rubble loaded filter 12 is provided with green layer 11.Not only achieve the effect that corrodes of rainwater-proof to domatic 15 of slope body 1, and allow the integrated environment in metallurgical slag stockyard be improved.Wherein, in order to reduce costs, general green layer 11 is made up of planting soil and the grass-seed planted on described planting soil.
In order to be drained in time by the rainwater converged on domatic 15, such improvement project can be selected: described cast-in-place basic 2 are provided with gutter 3 with domatic 15 intersections, and the groove 31 that the current on described domatic 15 surfaces converge to gutter 3 is discharged.As shown in Figure 1, the groove 31 in gutter 3 is positioned at and domatic 15 almost same levels bottom, like this, can well converge in groove 31 drain along domatic 15 rainwater flowed down.
Certain, the overall structure of slope body 1 is more polynary, such as, can also arrange cement stabilizing layer 4 at the end face of slope body 1.So not only as shown in Figure 1, then one deck slope body 1 can be built on cement stabilizing layer 4, also can be provided with planting soil 41 on cement stabilizing layer 4, thus the plants such as plantation trees, further improve the environmental quality in metallurgical slag stockyard.
In addition, for the metallurgical slag 14 near reinforced bar net in step b 13, the preferable range of described metallurgical slag 14 degree of compaction is degree of compaction >=93%.In addition, apart from domatic 15 degree of compaction >=90% within the scope of 1000mm, and require that equivalent friction angle is not less than 30 ~ 35 for best.The steadiness of metallurgical slag 14 entirety can be ensured like this.And for domatic 15 of step c, its preferably domatic 15 abrupt slope ratio of slope be 1:0.5 ~ 0.75, such abrupt slope ratio of slope is beneficial to timely draining most and ensures that the entirety of slope body 1 is firm.
