Description
Technical field
The utility model relates to a kind of integrated comprehensive arrangement of Dry-ash Yard in Valley draining, flood discharge, energy dissipating.
Background technology
Mountain valley-type dry type ash disposal area flood discharge is general comparatively large, according to water yield size, generally needs to arrange draining (oozing) system, flood discharge, energy-dissipating system and construction of structures thereof.The facility discharging flood in grey field is draining construction of structures, conventional vertical shaft (skewed slot)---lying pipe drainage pattern; The facility of the grey charge for remittance outside the venue of discharge is flood discharge construction of structures, the patterns such as conventional Cut-off ditch, flood spillway, abrupt slope; Draining and flood discharge all need to arrange energy dissipating, erosion control facility to eliminate water impact energy, generally have the pattern such as absorption basin, drop well, apron, protection-apron.
Originally generally drainage system, flood discharge, energy-dissipating system and construction of structures thereof are set all separately, this drawback of individually arranging: one is that dispersed placement floor space is large; Two are structural safetys to construction of structures, stablize unfavorable; Three is unfavorable to operational management; Four is that engineering quantity is large, and the comprehensive method of investment is higher.
Utility model content
The utility model achieves Dry-ash Yard in Valley draining, row is oozed, the construction of structures of flood discharge end forms an overall comprehensive arrangement, is recycled or outside discharge up to standard by the flood after energy dissipating by this comprehensive arrangement.
For achieving the above object, the utility model provides a kind of Dry-ash Yard in Valley draining flood-discharge energy-dissipating comprehensive arrangement, comprise impulse type stilling pool, drop energy dissipating well, gutter, drainage pipe, row's seepage well, gutter, abrupt slope, reuse pool, protection-apron, apron, it is characterized in that: impulse type stilling pool is arranged in ditch bottom, mountain valley, dam body downstream, grey field, gutter is arranged in the left side, impulse type stilling pool upstream, drainage pipe, row's seepage well is arranged on the right of impulse type stilling pool upstream, the gutter, abrupt slope be connected with Cut-off ditch, drop energy dissipating well is arranged in the impulse type stilling pool left and right sides, reuse pool for storing recycle-water is arranged in side, downstream, impulse type stilling pool side, protection-apron, apron is arranged in the downstream of whole comprehensive arrangement.
Good effect of the present utility model is as follows:
One is that each structure concentrate combined layout, compact conformation, saves and takes up an area.The land requisition index of object of construction production weighs engineering scheme important indicator economically and reasonably, the originally dispersed placement of routine, the structure such as impulse type stilling pool, drop energy dissipating well, row's seepage well are arranged in different level, different location, be communicated with by pipeline or raceway groove mutually, each structure all need occupation of land some, total floor space of taking up an area much larger than this concentrated combination layout structure after total;
Two is that each structure concentrate combined layout favourable to structural safety, is conducive to structure antiscour, overturning or slip resistance analysis, stability against slope.Each structure of original dispersed placement need to consider separately antiscour, overturning or slip resistance analysis, stability against slope, owing to limitting by each structure structure size, its independent antiscour, overturning or slip resistance analysis, stability against slope are poor, need additionally take reliable engineering measure to meet its stability requirement, adds additional design, construction works amount, increase part construction investment.After concentrating comprehensive layout, form a multi-functional associating overall, its physical dimension improves greatly, thus improves its antiscour, overturning or slip resistance analysis, resistant slide ability, just can meet the demands without the need to additionally taking engineering measure;
Three is save Structural Engineering amount, compared with dispersed placement, approximately saves engineering quantity 30%.This concentrates comprehensive arrangement, structural configuration design makes full use of between each structure and shares body of wall, save concrete and amount of reinforcement, support each other, can reduce difficulty of construction between each structure, save construction works amount;
Four is that centralized arrangement is favourable to operational management, saves safety and patrol, review time;
Five is cost savings.This concentrates comprehensive arrangement, through preliminary and dispersed placement Structure Comparison, can save gross investment about 22%.This structural shape has that floor space is little, security and stability is strong, save Structural Engineering amount, construction works amount, be beneficial to the advantages such as operational management, therefore can save total investment of engineering.

1, impulse type stilling pool 2, drop energy dissipating well 3, row's seepage well 4, reuse pool 5, gutter 6, drainage pipe 7, gutter, abrupt slope 8, protection-apron 9, apron 10, from gutter flood 11, from drainage pipe infiltration 12, from Cut-off ditch, abrupt slope flood 13, enter reuse pool flood 14, discharged to downstream flood.
Detailed description of the invention
With reference to Fig. 1,2,3, the impulse type stilling pool 1 of Dry-ash Yard in Valley is arranged in ditch bottom, mountain valley, dam body downstream, grey field, is beneficial to draining and energy dissipating; Ditch bottom, mountain valley rainwater by being arranged in the catch pit of impulse type stilling pool upstream, gutter 5 directly enters impulse type stilling pool; The inner rainwater of lime-ash, seeping water directly enters absorption basin energy dissipating discharge by the drainage pipe 6 that is arranged in impulse type stilling pool upstream, row's seepage well 3; Cut-off ditch is generally circular layout at the certain absolute altitude of massif, and for discharging the flood in more than stocking and storing lime-ash face, therefore gutter, connected abrupt slope 7, drop energy dissipating well 2 must be arranged in the absorption basin left and right sides; For store recycle-water reuse pool 4 according to the service condition of actual landform situation and recycle-water, the side that downstream, absorption basin side is easy to use can be arranged in; Protection-apron 8, apron 9 are the only ways of letting out under flood after absorption basin energy dissipating, for further energy dissipating and protective effect, therefore must be arranged in the downstream of whole comprehensive arrangement.
During this comprehensive arrangement design, according to grey field rank determination designed standard for flood control, calculate according to the inner flood discharge size in grey field the specification determining draining shaft, gutter, calculate according to flood discharge, flood level the specification determining impulse type stilling pool; The specification determining drainage pipe, row's seepage well is calculated according to row's water percolating capacity; Outside the venue according to ash import flood discharge size and calculate the specification determining Cut-off ditch, abrupt slope draining and drop well in portion; Protection-apron, the specification of apron and protection type is determined according to calculating discharged to downstream flood discharge size.
In ash field, flood and the row's infiltration outside the venue of flood, ash finally pools together through comprehensive arrangement, enters reuse pool recycling after multistage energy dissipating, or discharged to downstream.This comprehensive arrangement has played the function of each structure, fully demonstrates the advantage of comprehensive arrangement, namely saves occupation of land, reduces engineering quantity, to reduce investment outlay again, favourable to structural safety.
