Abstract
The invention discloses a hillside water seepage isolation system of an ardealite storage yard. The system comprises tensile anti-piercing geotextile paved on the surface of a rock side slope (10), and a high-density polyethylene (HDPE) film (2) which has a smooth outer surface and is paved below ardealite (20); multiple toothed bulges (3) are arranged at intervals and combined between the tensile anti-piercing geotextile and the HDPE film in a hot melting manner so as to form gaps serving as channels for the slope water seepage (4) to flow downwards. The system reduces the risk that the HDPE film is raised by the pushing of the slope water seepage, and well prevents the HDPE film from being pierced by rocks and other protruding objects on the slope; by adopting the HDPE film with a smooth outer surface, the system minimizes friction force between the HDPE film and ardealite, and effectively avoids the problems of downward dragging, tearing and the like of the HDPE caused by precipitation of ardealite. The slope water seepage isolation system can provide long-term reliable guarantee for isolating ardealite from slope water seepage.
Description
Technical field
The present invention relates to the ardealite storage yard construction project, particularly relate to the hillside infiltration shielding system of ardealite storage yard.
Background technology
Phosphorus is the important element that promotes animal and plant growth.Modern phosphor resource mainly obtains by the mode of using phosphate rock relieving haperacidity.There is abundant phosphate rock resource in China, and the apatite reserves account for 1/3rd of the world.World's phosphate rock output is used to produce phosphate fertilizer more than 90%.Wherein, producing phosphoric acid (wet method relieving haperacidity) by sulfuric acid and apatite reaction is a kind of mode that the most extensively adopts.By 2007, China has surpassed the U.S. became the big production of phosphate fertilizer of the first in the world state.With phosphorus pentoxide (P
2O
5) the phosphoric acid output calculated, about 1,300 ten thousand tons of China, about 1,200 ten thousand tons of the U.S..
In the process of wet method relieving haperacidity, can produce a large amount of by-product ardealites.The P that every production is one ton
2O
5, with the by-product ardealite that produces 4.5 to 5.5 tons.Ardealite is mainly by calcium sulphate dihydrate (CaSO
42H
2O) form, and contain a spot of silicide and unreacted rock phosphate in powder.The ardealite total amount of the annual discharging of China is above 5,000 ten thousand tons.
Ardealite has the higher characteristics of solubility, and ardealite density, the intensity of being soaked by clean water reduce, and is unfavorable for that the slag field is stable.Therefore, doing the ardealite side slope that heap ardealite slag field or backer heap builds all need avoid contacting with the hillside infiltration.Traditional partition method comprises uses argillic horizon or individual layer antiseepage film that hillside and ardealite are isolated.Yet because the clay shear strength is low, the clay separation layer can't use in the steeper zone of the gradient.Simultaneously, also there are the characteristics of cost height, quality control on construction difficulty in the clay separation layer.And the individual layer antiseepage film is covered on ever-increasing and is easy under the effect of ardealite pressure be punctured by the rock on the hillside and protrusion and loses its water-proof function.
Summary of the invention
The technical problem to be solved in the present invention provides the hillside infiltration shielding system of the ardealite storage yard of a kind of isolated stably in a long term ardealite and hillside infiltration.
For solving the problems of the technologies described above, the invention provides a kind of hillside infiltration shielding system of ardealite storage yard, it is characterized in that, be included in the tension of the rock slope surface laying of ardealite storage yard, the anti-geotextiles that pierces through, and the density polyethylene film with high of the smooth outer surface of laying under the ardealite in ardealite storage yard, in described tension, anti-piercing through between geotextiles and the described density polyethylene film with high is combined with a plurality of spaced detent projection, described tension with the hot melt form, anti-space of piercing through between geotextiles and the described density polyethylene film with high forms the passage that the hillside infiltration flows downward.
Described smooth density polyethylene film with high be many density polyethylene film with high along side slope lay from top to bottom, and will the synthetic integral body of adjacent density polyethylene film with high soldered and form.
The commissure nail of described adjacent density polyethylene film with high has density polyethylene film with high is fixed on soil nailing on the side slope.
On density polyethylene film with high, described soil nailing exposes the place and with adhesive tape density polyethylene film with high and soil nailing combined.
On density polyethylene film with high, described soil nailing exposes the place, the edge of soil nailing and density polyethylene film with high extruding weld together.
The hillside infiltration shielding system of ardealite storage yard of the present invention, owing between tension, the anti-density polyethylene film with high that pierces through geotextiles and water proof, be provided with dentation, thereby between geotextiles and water proof material, formed the space, make that the hillside infiltration can be that passage flows downward with this space, thereby reduced water proof material (being the HDPE density polyethylene film with high) by the risk of hillside infiltration jacking protuberance.Simultaneously, the space between geotextiles and geotextiles and the density polyethylene film with high is provided excellent protection for preventing density polyethylene film with high by the rock on the hillside and other protrusion bursting.And the density polyethylene film with high smooth outer surface that the present invention adopts, thus frictional force between density polyethylene film with high and the ardealite reduced to greatest extent, effectively avoided density polyethylene film with high problem such as to drag, tear down because of what the ardealite sedimentation caused.In a word, the present invention can provide safeguard for completely cutting off the infiltration of ardealite and hillside stably in a long term.
Further in the technical scheme, the present invention is fixed on density polyethylene film with high on the hillside with soil nailing, in order to the uplift force of opposing wind to film, in the form of soil nailing exposure place film and soil nailing are combined with adhesive tape or extruding welding, be distributed on the density polyethylene film with high thereby the resistance to plucking of soil nailing is played strength, avoided stress to concentrate.
Description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the hillside infiltration shielding system structure cross-sectional schematic of ardealite storage yard of the present invention.
Fig. 2 is the floor map that smooth density polyethylene film with high is laid.
The specific embodiment
As shown in Figure 1, the hillside infiltration shielding system of ardealite storage yard of the present invention, mainly be included in the tension of the rock slope surface laying of ardealite storage yard, the anti-geotextiles 1 that pierces through, and being used for of laying under the ardealite in ardealite storage yard is the density polyethylene film with high 2 of the smooth outer surface of ardealite water proof, in described tension, anti-piercing through between geotextiles 1 and the described density polyethylene film with high 2 is combined with a plurality of spaced detent projection 3, described tension with the hot melt form, anti-space of piercing through between geotextiles 1 and the described density polyethylene film with high forms hillside (among the figure shown in the curved arrow) passage that flows downward that seeps water 4.As shown in Figure 2, described smooth density polyethylene film with high 2 are many density polyethylene film with high along side slope lay from top to bottom, and will the synthetic integral body of adjacent density polyethylene film with high soldered and form, weld seam 6 places nails has density polyethylene film with high is fixed on soil nailing 5 on the side slope, on film soil nailing 5 expose the place with adhesive tape or with the extruding welding with density polyethylene film with high 2 and the soil nailing (not shown) that combines.
