Description
Technical Field
The invention relates to the technical field of building engineering materials, in particular to an artificial solidified stone for energy dissipation and bank protection or energy dissipation and scour prevention and an application method thereof.
Background
According to statistics, the total length of the built embankment is 41 thousands kilometers, wherein most of embankments are 4-grade and lower-grade embankments. In river super protection and super police in flood season, the dyke is often in danger of instability, collapse, burst and the like on the water slope. The most common effective method for emergency protection in dangerous cases is to adopt riprap, soil engineering bags to stabilize slope toe, prevent scouring, heighten embankment and plug burst. According to the related flood prevention material storage requirements, 50-500m3 block stones and 20-600m3 sand stones are required to be stored in each kilometer of dikes according to the engineering grade. However, in recent years, along with the increasing importance of our country on natural resource protection, mountain-mining and quarrying are forbidden in some areas, so that the source of natural stone, which is an important flood-prevention engineering material, is limited, so that some embankment engineering can be used without stones or only crushed stones with small size can be obtained, and a hidden danger is formed on the safe operation of hydraulic engineering.
Most of traditional ripstones are irregular spheres and are discrete bodies which are not connected with each other, most of the ripstones are small in particle size and are easy to be wrapped and washed away under the impact of water flow, the effect of ripstone protection is lost, particularly for plugging of a burst opening, due to the fact that the flow rate of the burst opening is large, all hydraulic indexes are far beyond those of the conventional ripstone blocking and throwing, particularly for the burst opening with the flow rate of 6-8 m/s and the water depth of 10m, the estimated throwing unit weight is 2.6 t-17 t and can be remained in the burst opening without being washed away, and the existing conventional ripstones cannot meet the conditions.
The steel slag is the waste slag discharged in the metallurgical steelmaking process, and mainly comes from oxides formed by oxidation reaction of calcium, aluminum, iron, manganese, magnesium, vanadium, chromium, silicon, phosphorus and sulfur elements in added furnace burden, impurities such as silt carried by the furnace burden and the like, slag formers such as lime, dolomite, silica, fluorite and the like added in the steelmaking process, coolants and oxidants such as iron ore, sintered ore, iron scale and the like, corroded steel-making furnace lining materials, furnace repairing materials for filling the steel-making furnace and the like. The main chemical components of the steel slag include CaO, SiO2, A12O3, FeO, Fe2O3, MgO, P2O5, f-CaO and the like. The main mineral components in steel slag include dicalcium silicate (2CaO SiO2), tricalcium silicate (3 CaO. SiO2), olivine (FeO. SiO2), dicalcium ferrite (2 CaO. Fe2O3), etc. In addition, with the continuous promotion of hydraulic engineering and urban traffic construction, a large amount of waste earthwork is generated in the construction process of some new projects. The conventional disposal mode of the steel slag and the waste earthwork is to pile or bury the steel slag and the waste earthwork in different places, which not only has high transportation cost, but also occupies a large amount of valuable land resources to cause land waste, and is often accompanied by geological disasters such as landslide and landslide or risks of underground water environmental pollution, and because the steel slag contains more alkaline substances such as f-CaO and the like, the steel slag also causes considerable harm to the underground water quality and the growth of plants and also causes great pollution to the surrounding environment.
Therefore, in order to solve the problems of the shortage of natural stones and the difficulty in disposing the waste earthwork and the steel slag, the invention provides an artificial solidified stone prepared from the steel slag and the waste soil to replace the natural stones, and application of the artificial solidified stone in the aspects of large dam breach plugging, river bottom energy dissipation and scour prevention, river slope protection, energy dissipation and scour prevention and the like.

Example 2
The artificial solidified stone for energy dissipation bank protection or energy dissipation scour prevention in the embodiment 1 is prepared from the following raw materials in parts by weight: 10 parts of cement, 20 parts of waste soil, 70 parts of steel slag, 0.8 part of curing agent (the mass ratio of calcium aluminate to sodium sulfate is 70: 15: 15), and 1.2 parts of water reducing agent polynaphthalene sulfonate NS; the preparation method comprises the following steps: s1, pretreating the spoil and the steel slag: spreading and drying the waste soil body raw material, manually removing soil body impurities, air drying and aging, and mechanically crushing by adopting a hammer crusher to ensure that the granularity of the waste soil body raw material reaches below 5 mm; the steel slag is placed and aged to be fully expanded and pulverized, and then the steel slag is mechanically crushed and screened to ensure that the granularity of the steel slag is below 5 mm; s2, weighing the materials according to the parts by weight; s3, performing dry mixing on the crushed waste soil, the crushed steel slag and the cement, adding a proper amount of water, an excitant and a water reducing agent into the dry mixture, performing wet mixing, and fully stirring the mixture with water to obtain slurry; s4, pressing and forming the obtained slurry by a hydraulic forming machine under 20MPa to obtain an artificial cured stone blank; and S5, naturally curing the artificial solidified stone blank for 28 days to obtain the artificial solidified stone.
Examples 3 to 5
The difference between examples 3-5 and example 2 is that the steel slag used in the formulation has a different ratio to the spoil, i.e. a different steel slag substitution rate, the specific ratio is detailed in table 1, and the others are the same as those in example 1.
Comparative example 1
The difference between the comparative example 1 and the example 2 is that the steel slag is not used in the formulation, and all the steel slag is changed into the spoil, and the rest is the same as the example 1.
The artificial solidified stones prepared in examples 2 to 5 and comparative example 1 were subjected to mechanical property tests, and the results of the property tests are detailed in table 1.
TABLE 1 mechanical Properties of artificially solidified Stone with different Steel slag substitution rates
| Waste soil% | Steel slag% | Steel slag substitution rate% | Compressive strength (MPa) | |
| Example 1 | 20 | 70 | 77.8 | 25.4 |
| Example 2 | 30 | 60 | 66.7 | 23.3 |
| Example 3 | 50 | 40 | 44.4 | 15.1 |
| Example 4 | 70 | 20 | 22.2 | 11.2 |
| Comparative example 1 | 90 | 0 | 0 | 8.9 |
The results in table 1 show that the compressive strength of the artificial solidified stone can be remarkably improved by adding a certain amount of steel slag, the strength of the artificial solidified stone is remarkably improved along with the improvement of the replacement rate of the steel slag (the proportion of the steel slag and the spoil), and when the replacement rate of the steel slag reaches 77.8%, the compressive strength of the produced artificial solidified stone can reach 25.4 MPa. The main reason is that the particle size of the waste soil is small, the content is low, the artificial solidified stone made by only using soil as aggregate is difficult to completely meet the requirement of reasonable range of gradation, a certain amount of thicker steel slag aggregate is added into the raw material ingredients, which is not only beneficial to the durability of the product, but also more important is that the material gradation is adjusted after the steel slag aggregate is added, meanwhile, in the pressure molding, the steel slag aggregate plays a role in transferring pressure, the phenomena of uneven density, suffocating and layering and the like caused by the uneven density, and the mechanical strength of the artificial solidified stone is increased.
