Background technology
As national basis construction project largely enters outlying mountain area, limited by topography and geomorphology, engineering construction project difficulty
Greatly, engineering project place needs evaluation, and retaining amount is huge.Traditional retaining mostly using concrete guard wall,
Piece (block) stone barricade is grouted, sluices and spilled water hole is set using in wall.In Practical Project construction, barricade wall carries on the back pervious bed in mud
Starch, fail under the repeated action of drift sand, cause barricade spilled water hole that stifled (silt) plug occurs, cause barricade impeded drainage, wall back of the body side slope
Level of ground water raises, and produces ponding.Under the action of ponding, Plastic flow of soil and shearing resistance drastically decline side slope, soil layer Weak face
Form the sliding surface of perforation, side slope easily unstability.Huge sliding force and head pressure, which is acted on barricade wall, causes barricade
Collapse, cause huge loss.According to country and investigation and analysis of the relevant department to engineering accident, the original that retaining collapses
Cause, is because barricade impeded drainage causes mostly.
Traditional retaining, because using fluid-tight materials for wall, spilled water hole is only leaned in draining, and individually using sluicing

The content of the invention
There is a kind of mixing material of pervious function using the present invention, can meet to construct traffic, water conservancy, environmental protection, building,
Mine, the design requirement of erosion and torrent control works barricade, and the ponding in barricade can be oozed through wall and discharged.Change only
Using the traditional approach of spilled water hole draining, the side-thrust for reducing the meeting water reduction and head pressure of soil and being produced to barricade.
To achieve these goals, present invention employs following technical solution：
The present invention has selected yellow phosphorus (P4) produce the industrial residue (hereinafter referred to as phosphorus slag) discharged.It is a certain proportion of adding
Sub-fraction phosphorus slag ball milling is simultaneously become a kind of new permeable mixing material by gypsum, lime into incorporation after subdivision.Make it have
Preferable gelling.Again since water quenching phosphorus slag contains more transparent vitreous body and active loose structure, it is allowed to and has
There is permeability.
Phosphorus slag is in producing yellow Phosphorus by electric oven, and the mixture of rock phosphate in powder, silica, coke is added in electric furnace, is passed through electricity
Thermal energy can be converted into, is melted and produces chemical reduction reaction, extract yellow phosphorus (P4) after, arranged outside cinder notch, water quenching and obtain.Enter
CaO and SiO in stove ore2It is the main component of slag making in phosphorus production.
The main chemical compositions of phosphorus slag are shown in Table 1

| SiO2 | 40~43 | 38.45 |
| Al2O3 | 2.0~8.0 | 2.83 |
| MgO | 0.8~2.5 | 2.27 |
| Fe2O3 | 0.2~1.0 | 0.27 |
| P2O5 | 0.8~3.5 | 1.93 |
| F | 1~3 | / |
Phosphorus production consumption rock phosphate in powder per ton (grade 25% is counted)：8.5-10 ton, silica：0.3-2.5 tons, coke：1.5-
2.0 tons, enter stove total amount generally at 10-14 tons, exclude 8-10 tons of clinker.
After molten slag water quenching, the grey particulate of 0.2-1.2mm is obtained, through lithofacies analysis, phosphorus producing furnace slag is mainly β-C2S
(β-2CaO、SiO2) and C5A3(5Ca-Al2O3) and contain more transparent vitreous body and active loose structure.It is relatively close

The gelling of phosphorus slag.The Al of phosphorus slag2O3Content is low, it is difficult to hydrated calcium aluminate sulfate is generated, so to add appropriate Al2O3
Material.Since phosphorus slag contains more transparent glassy thing, the unstability and imbalance of its glass structure have it
There is higher lateral reactivity.When making alkali-activator with suitable lime, when making sulphate activation agent with gypsum, in the two composition
Composite exciting agent excitation under, be possible to make the irregular aluminate in part, silicate be rearranged to a certain degree
And chemical reaction, generation hydrated calcium aluminate sulfate, hydrated silicate and aquation aluminate etc., so as to have preferable gelling property.
The strength characteristics of phosphorus slag.Although phosphorus slag is hydraulic cementing materials, add be not as after water Portland cement that
The rapid aquation of sample, solidification.Its key is because the colloid for having silicic acid shape surrounds and adsorb the β-C in slag2S (dicalcium silicate) table
Face and surrounding.Water is not easy directly to contact into rearrangement and chemical reaction during aquation.So early strength is low, oozed by certain time
Just chemically reacted thoroughly, make later strength increase very fast.
The activity of phosphorus slag.Phosphorus slag is to melt in electric furnace under 1400 degree of high temperature, enters granulating pit after the exclusion of clinker mouth, into
Row water quenching.It was verified that water and slag ratio and the flow velocity slagged tap are suitable, are conducive to increase the amount of glass phase, early strength can be improved.
Simultaneously because the composition of phosphorus slag is mainly silicate, wherein C2S (dicalcium silicate) has α, β, γ, only three kinds of variations, α, β body
With gelling, part β-C can be prevented using quenching water quenching2S is converted into γ-C2S and cause cement dusting lose intensity.Together
When by water quenching can change physical property, ensure the integrality of grain slag granulating, improve the activity of phosphorus slag.
