Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, the technical solution below in the present invention carries out clear Chu is fully described by, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts Embodiment shall fall within the protection scope of the present invention.
Fig. 1 is recycling canal body structural schematic diagram;
Liquid channel building brick wall is being received, brick wall by massif one side there are the gap of infiltration, accomplish not permeable on one side by brick wall back of the body massif Water, channel bottom do Anti-seeping technology, and metalling or sand bed are filled up by lower layer in channel, and thin bamboo, channel bottom are filled out in channel upper layer PVC water pipes are buried, aperture is opened on PVC water pipes.
As Figure 1-1, thin bamboo is filled out in receiving liquid channel:It is 0.8m, depth 0.8m to receive liquid channel width;It can also basis Actual conditions, which determine, receives liquid channel width and depth.Gap can not only become the access of soil middle rare earth mother liquor between thin bamboo, Also it is effectively prevented to receive liquid channel and cave in and leads to receive liquid obstructed channel, thin bamboo is in southern RE ore mountainous region table common materials, section About cost of investment.It lays bricks in receiving liquid channel wall, fills out metalling (sand bed):Wall of laying bricks by massif one side there are the gap of infiltration, Wall of laying bricks back of the body massif one side is accomplished impermeable as possible, and metalling (sand bed) and embedded PVC water pipes are filled up in centre.The method and thin bamboo Gap can play same effect between pole.Channel bottom also does Anti-seeping technology, prevents mother liquor from being oozed from channel bottom when receiving liquid Flow and cause the loss of resource.
Further, liquid channel bottom addition diameter 10cmPVC water pipes are being received, using the center line of PVC water pipes as the center of circle, vertically PVC centre of conduit line and the straight line on ground become the both sides of angle to both sides rotation, in closely 120 degree of angle regions of apparent bearing The aperture for inside opening a diameter of 5mm by phased manner is subsurface collector rare earth mother solution trunk access, just straight if rare earth mother solution amount is big Underground PVC water pipes water conservancy diversion was connected to rare earth mother solution collecting pit.
As shown in Figs. 1-2, it receives liquid channel and mother liquor collection surface to lay bricks wall, there are the gaps of infiltration for brick wall, so as to rare earth Mother liquor can pass through, and enter rare earth mother solution collecting pit.
As shown in Figs. 1-3, the cross-section diagram for receiving liquid channel is excavated at the hillside for receiving liquid channel oblique upper 4m or so and is parallel to Mother liquor collects the flood diversion channel of canal:Southern area rainwater is relatively more, and when raining, the surface water meeting fair current of massif is collected to mother liquor In channel, the production cost of Rare-earth Mine enterprise is not only also added, but also is possible to come down in massif gradient larger part. Canal flood diversion channel, the surface water water conservancy diversion that most of fair current is got off to designated position are collected so excavating and being parallel to mother liquor.
Technology illustrates and theory analysis:
Previous mother liquor is collected canal and is directly excavated into irrigation canals and ditches in the massif underfooting in fluid injection area, and exudation rare earth mother solution water conservancy diversion is arrived Mother liquor collecting pit.Irrigation canals and ditches are excavated at massif side slope slope foot, are carried out cutting slope processing equal to side slope slope foot, are cut slope Slope Stability Property causes prodigious security risk.In process of production, wash away corrosion function of the mother liquor to channel, mother liquor take advantage of a situation along channel and Under, mother liquor is mainly in the process with mechanical erosion with the power of itself and with the both sides of the soil erosion canal body of its carrying It is main, cause canal body to widen, this process is that the lateral erosion of flow acts on;During mother liquor flow down, due to gravity The gravitional force of flowing water is formed, and is constantly converted into kinetic energy, the sand and gravel of flowing water and its carrying are hit, rub canal body bottom Portion makes canal body bottom solum or basement rock weather and denude and gradually destroy, bottom of trench by incision, make channel by lower erosion increasingly Deep, channel deformation is increasingly severe, causes massif side slope more and more unstable.In addition previous intercepting gutter is typically no special Tidal channel, after heavy rain, rainwater is discharged to mother liquor collecting pit also with intercepting gutter, and southern warm is rainy, and rainwater not only adds The corrosion function of acute canal body, and mother liquor is further processed and brings larger workload;With this simultaneously as irrigation canals and ditches are straight Excavation is connect, Anti-seeping technology is not carried out to irrigation canals and ditches, can be caused to be lost in due to osmosis in mother liquor to a certain degree, in south In weathered crust-eluvial rare-earth mine, shallow-layer soil property is generally humus layer, loosely organized, and mechanical strength is not high, be easily washed and Infiltration coefficient is higher, and canal body soil layer causes canal body easily to collapse since osmosis is easily softened, and penstock side hillside easily occurs Unstable phenomenon during collection, often occurs to excavate mother liquor collection irrigation canals and ditches under the action of flow with many silts to mother liquor Collecting pit is cleared up bothersome laborious;It collects irrigation canals and ditches to collapse in exudation one face massif of rare earth mother solution, gently then mother liquor is caused largely to flow Mistake can not recycle, heavy then cause damp production, production facility by dilapidated or it is possible that casualties.
This canal body upper layer is laid with thin bamboo, and lower layer is filled with rubble and a diameter of 10cmPVC water pipes are buried in bottom, in PVC Open a diameter of 5mm apertures by phased manner (close in 120 degree of angle regions of earth's surface) on water pipe, as drainage mother liquor major trunk roads, The gap between gap and lower layer's rubble between this canal body upper layer thin bamboo can also be used as the channel of mother liquor water conservancy diversion;Lower layer fills Rubble and upper layer be laid with thin bamboo can play support canal body structure and maintain its shape, largely slow down by In mother liquor to the souring of canal body;Canal body side surface and bottom are built into anti-seep measure with brick, it is possible to reduce the waste of mother liquor, Improve the rate of recovery of rare earth resources;
It is excavated at the hillside for receiving liquid channel oblique upper 4m or so and is parallel to the flood water conservancy diversion channel that mother liquor collects canal, kept away Exempt from rainwater and flow into mother liquor pond together with mother liquor, on the one hand prevents heavy rain from carrying a large amount of silt and directly wash away mother liquor diversion channel body, Cause canal body to be filled by silt to block or cause to canal body structural damage;On the other hand it can prevent rainwater from flowing directly into mother liquor Pond is further processed the workload for bringing bigger to mother liquor.
Support force of the canal body rubble to canal body:
Canal body excavate position be generally located at the slope foot of massif, slope foot it is no excavate at canal body and without fluid injection it Before, massif side slope is in stable state;When slope foot is after excavating canal body, the stable state of side slope starts to be destroyed, with The progress of massif fluid injection, when the shearing strength for the soil body that the maximum shear stress suffered by the side slope is more than side slope, side slope is then Unstable failure can occur.Overburden layer is with cohesive soil in south jiangxi Rare Earth Mine, lower part based on weathering and half weathered rock formation, and thickness compared with It is deep, therefore its permeability is preferable, mechanical strength is relatively low, and wherein soil layer cohesive strength is varied widely with mine fluid injection intensity, with The passage of fluid injection time, side slope soil layer cohesive strength decline, and internal friction angle also reduces therewith;The shearing strength of side slope and soil layer Cohesive strength and internal friction angle are proportional, and when cohesive strength and internal friction angle reduce, the shearing strength of side slope is also therewith Reduce;When side slope slope foot is excavated into canal body, side slope slope foot is in the state being sheared, in the side of massif due to note The effect of liquid seepage flow has emollescence to the soil layer of canal body side, and with the growth of fluid injection time, canal body holds very much by side slope side The consequence collapsed is easily caused, and then is likely to induce slope and land slide.The invention carries out landfill reinforcing with rubble to canal body, and canal body leans on Massif side slope side is played a supporting role, when can effectively slow down massif fluid injection side slope soil layer soften and after causing slope instability Fruit.
The present invention is not limited by production scale, does not change ionic type rare earth ore in-situ extract technology, simple in structure to be applicable in, easily Operation, at low cost, production environment is friendly, pollution-free.
Finally it should be noted that:The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although Present invention has been described in detail with reference to the aforementioned embodiments, it will be understood by those of ordinary skill in the art that:It still may be used With technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features; And these modifications or replacements, various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution spirit and Range.
