Description
Technical field
The present invention relates to a kind of construction technology technology, specifically relate to the step pump standing posture drainage system for draining in built acid waste water regulation warehouse and technique.
Background technology
Along with the exploitation in more and more sulphide ore mine, in mine, the waste-rock yard of low position barren rock stored up by stope and being used for, the draining that its rainfall leaching produces mostly is containing acid waste water containing heavy metal ions, in order to meet mine water supply balance and environmental requirement, usually need to arrange acid waste water regulation warehouse to store and regulate, and small pieces of cloth used for patches HDPE antiseepage film carries out Anti-seeping technology, newly-built waste water regulation warehouse can arrange the drainage of complete set usually, but mine is for a long time exploited for some, because built acid waste water regulating time is remote, mining is intermittent, and the factor such as field control is ineffective, drainage in its storehouse can not use mostly, for the acid waste water regulation warehouse of this situation, newly-built a set of drainage is very necessary.
In built acid waste water regulation warehouse, the existing technique of draining mainly contains: fixed pump standing posture drainage technology, inverted-siphon formula drainage technology and movable pump station formula drainage technology.Wherein fixed pump standing posture drainage technology needs in storehouse built-in fixed pump station, and this will bring pumping plant basis preservative treatment, and easily destroys the problems such as reservoir area antiseepage film.Inverted-siphon formula drainage technology then can be subject to the restriction of water level in storehouse and water fully can not be drained.Movable pump station formula drainage technology can bring the anticorrosion difficult problem of pumping plant equally, and the aspects such as the operation of pumping plant, management, maintenance are more difficult.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existed for existing built acid waste water regulation warehouse drainage pattern, proposes a kind of restriction not destroying impervious element, be not subject to water level in storehouse, and can ensure drainage system and the method for construction safety.
The present invention realizes above-mentioned purpose by the following technical solutions.The step pump standing posture drainage system of built acid waste water regulation warehouse, key dam body is disposed with first order platform and second level platform from the inside to the outside to the side in storehouse, bottom surface and the end face of described first order platform and described second level platform are all equipped with geo-grid, and be provided with interlayer between described bottom surface to described end face, interlayer is equipped with geo-grid, the periphery of described first order platform and described second level platform is all with geotechnological Filter-screen bag, and the end face of key dam body, first order platform or second level platform is all provided with self priming pump according to corresponding water level.
The spacing of described interlayer is 2 ~ 3m.
A technique for the step pump standing posture drainage system of built acid waste water regulation warehouse, its step is as follows:
Step 1, built acid waste water regulation warehouse key dam body arranges self priming pump, water level in storehouse is drained into first row water level;
Step 2, utilizes lifting appliance to sink in storehouse in water by earth bag, and at next-door neighbour key dam body place, heap is built;
Step 3, adopt inverse row's mode, from the base of dam of key dam body, sink to earth bag, and move back platform to the dam crest direction of key dam body, the bottom of first order platform and top are all equipped with geo-grid interlayer, and the bottom of first order platform and crown center interlayer lay geo-grid;
Step 4, after first order table top exceeds the water surface, be with geotechnological Filter-screen bag at its edge, intermediate hierarchical bankets;
Step 5, then self priming pump on key dam body top is moved to first order table top carry out draining, the water level in storehouse is drained into second row water level;
Step 6, and again utilize lifting appliance to sink in storehouse in water by earth bag, at next-door neighbour first order platform place, heap is built;
Step 7, repeats step 3 and step 4, is close to first order platform place and piles to build again and form second level platform, and move on on the platform of the second level by the self priming pump on first order platform in storehouse;
Step 8, drains into the 3rd water level H6 with the self priming pump on the platform of the second level by water level in storehouse, storehouse Nei Shui can be drained into face, bottom of the reservior.
The invention has the advantages that: 1, can construct under the condition not destroying built acid waste water regulation warehouse impervious element.2, season is little to this drainage technology construction infection.3, major part is constructed on the coast, and subaqueous construction is less, and working security is higher.4, can water level in storehouse be drained into minimum.Therefore in some specific acid waste water regulation warehouses, draining has advantage.
