Abstract
Vertical row is oozed the water seepage drainage facility that vertical shaft and horizontal drainage pipe combined seeping water discharging body belong to accumulation of dam.It mainly forms vertical row by geotextile cloth bag gravel and oozes vertical shaft, has the pipeline that has hole of geotextile cloth to constitute horizontal drainage pipe by wrapping, and oozes silo bottom butt joint formation combined seeping water discharging body in vertical row.Thereby realize reducing dam seepage line from oozing from row.This drain system is difficult for silting up convenient management without water pumping power.When earthquake, can dissipate effectively owing to the pore water pressure of earthquake generation, reach the purpose of dam body consolidation.
Description
The invention belongs to the water seepage drainage facility of accumulation of dam.
There are a lot of tailing dams, ash dyke and part earth dam in China, owing to reasons such as dam body water seepage drainage facility imperfection or heap dam methods, causes dam seepage line to raise, exposure from the dam slope face, seepage and failure by piping are concentrated in the also generation that has, and seriously influence the safety of dam body, and dam-break accident happens occasionally.In the earthquake zone, when earthquake takes place,, cause dam body side slope slumping because the dam seepage line height causes the inner pore water pressure that produces owing to earthquake of dam body to increase, cause that whole dam body destroys.
In order to reduce the phreatic line of dam body, need take the water seepage drainage and reinforcement measure, used water seepage drainage facility has at present: level row is oozed french drain, the anti-filter row in subsides slope blends the vertical row seepage well.
The vertical row seepage well uses sand-free concrete tube, steel pipe with holes or cast iron pipe outsourcing loaded filter to form row's seepage well, and draws water to discharge in the seepage well with deep well pump and seep water.This method power consumption is big, uses one period or the improper seepage well that turns round easily to deposit, and also drawing water because of mechanical brute force causes that shaft wall structure destroys, and particularly pump-out and water percolating capacity imbalance make the pump working inequality, and water level can fall.Big stone river ore deposit changed syphon row infiltration in 1986, and light well point is adopted in the ore deposit, South Mountain, and the water jet flow negative pressure draws water.
In December, 1986, ore deposit, length of bow mountain range is aimed at vertical shaft jacking steel pipe from dam facing and is oozed silo bottom with row and join, and cancelled water pumping power, but horizontal steel tube only plays drainage, does not ooze function and there is row, can not dissipate owing to seimic pore water pressure.
The invention reside in the drain system that proposes new structure, not only can arrange the infiltration of oozing vertical shaft from flowing out, and be higher than under the effect of horizontal drainage pipe differential water pressures in underground infiltration position, underground infiltration constantly is discharged to outside the dam voluntarily by horizontal drainage pipe.
Accompanying drawing 1 oozes vertical shaft and horizontal drainage pipe combined seeping water discharging body diagrammatic sketch for dam body and vertical row.
Accompanying drawing 2 oozes shaft structure figure for vertical row.
Vertical row is oozed vertical shaft and horizontal seepage pipe combined seeping water discharging body and is oozed vertical shaft 1 and horizontal seepage pipe 2 by vertical row and ooze the silo bottom docking row and form. Row is oozed vertical shaft and is formed by geotextile cloth bag 3 in-built gravels 4, oozes the vertical shaft center row and is embedded with percolation line vertical tube 5, and vertical shaft top has reinforced concrete platform 6 to bind. Horizontal seepage pipe is opened pertusate pipeline 7 wrapping geotextile cloth 8 by many and is consisted of, and links with pipe collar 9 between pipe. Each size of drain system, visual use need to be determined.
Main points of the present invention are that horizontal pipe is made up of drainage pipe in the combined seeping water discharging body, and vertical row is oozed vertical shaft and formed by dress gravel in the geotextile cloth bag, and vertical row is oozed vertical shaft and docked formation combined seeping water discharging body with horizontal drainage pipe.
It is effective that vertical row is oozed the anti-filter of vertical shaft among the present invention, is difficult for silting up, and horizontal drainage pipe plays row and blends the draining double action, this drain system need not manpower and mechanical forced draw water, but by the inner own infiltration degree of passing of dam body, reach from oozing from row, reduce dam seepage line.This drain system use and management is convenient, the pore water pressure that particularly can dissipate effectively when earthquake and produce owing to earthquake, the stability of increase dam body.
Embodiment:
Vertical row seepage well: 15 meters of well depths, 0.8 meter of geotextile cloth bag diameter, the gravel that interior dress particle diameter is 10～30 millimeters, 90 millimeters of center observation vertical tube diameters.
Horizontal drainage pipe: use anticorrosive plastic pipe, 50 meters of length overalls, 90 millimeters of calibers, boring on the pipe, the geotextile cloth that outsourcing is thick 5 millimeters, pipe collar are the socket and spigot joint of aluminium matter.
