Study on effect of spillway trough on deposition efficiency of intermittent scouring sand basins;
溢流槽對定期沖洗式沉沙池沉淀效率的影響分析研究
Traditional sediment tank has been improved in three aspects by putting an adjusting flow wall in the entrance of water, a spillway trough on spillway crest along the flow direction, redesigning the flush device and an auxiliary fl ush facility.
通過在沉砂池的進水處加調流墻、在溢流堰上沿水流方向設溢流槽、對排砂裝置進行改進以及設置輔助沖砂設施三個方面對傳統平流式沉砂池進行了改進,設計提出了一種新型平流式沉砂池,可以大大提高沉砂池的沉淀效率,特別是對細顆粒泥砂的沉淀具有很好的效果。
, setting an adjusting flow board in the fore of setting basin, adding a spillway trough along the flow direction, and redesigning the flush gallery by adding auxiliary flushing facilities.
在對各種類型沉沙池及適用條件進行分析的基礎上,通過在沉沙池的首部加調流板、在溢流堰上沿水流方向設溢流槽、對沖沙廊道進行改進并設置輔助沖沙設施這3個方面對傳統沉沙池進行了改進。
