Description
Technical field
The utility model belongs to the layout field of fixed-end forces field, particularly relates to the linkage structure of a kind of percolate discharge guiding pipe and dam-through pipe.
Background technique
In recent years for minimizing domestic waste is to the pollution of environment, city above county level is successively dropped into substantial contribution and is built Sanitary Landfill to substitute Mini nutritionalassessment in the past.Wherein, reservoir area antiseepage, leachate collection guide system, percolation liquid treating system are the innoxious important component parts of municipal solid waste sanitary landfill, and anti-seepage effect directly affects domestic garbage was harmlessly treated effect.Find through oversampling investigation, after the landfill yard of more than 90% comes into operation, successively occur the phenomenon of leakage of leachate.Cause the reason mainly antiseepage film partial fracture of seepage.The reason of antiseepage film partial fracture is caused to have: the destruction of landfill operation machinery; Foundation settlement is uneven and pressure-bearing is uneven and generation is torn; Welding procedure is with low quality causes joint broken; Underground water is emptied bottom of the reservior bed course and is caused antiseepage film to be torn.
Because landfill site seepage prevention membrane area is huge, check that the leak source of antiseepage film local is very difficult.According to leakage detection construction experience for many years, find antiseepage film break occur in bottom of the reservior percolate guide supervisor through during rubbish key dam and the probability of antiseepage film joint, reservoir area the highest.The antiseepage film of joint easily produces tears, and there is design deficiency, and it is mainly reflected in three aspects:
(1) working space around dam-through pipe 360 degree of circumference soldering constructions is not considered; Working space is narrow and small causes dam-through pipe near the one side welding procedure difficulty of bottom of the reservior blinding layer, and near bottom of the reservior blinding layer interface often not prison welding, not in place, welding quality is difficult to ensure.
(2) do not consider that the shearing force difference of joint is responsible in dam-through pipe and bottom of the reservior percolate guide.Along with the continuous increase of junk-heap body, the sedimentation of bottom of the reservior sedimentation change and waste dam changes and there will be significant difference, bottom of the reservior percolate guide supervisor and dam-through pipe jointing is caused to be out of shape, to rupture, after pipeline break, rubbish brings dam-through pipe under the flowing of percolate, constantly entering of rubbish can block dam-through pipe, and the percolate guide system of whole reservoir area can be caused time serious to scrap.
(3) existing design is not easy to inspection, the maintenance of operation stage.
