泥砂泵 的英文怎麼說
中文拼音 [níshābèng]
泥砂泵
英文
mud sand pump-
This thesis investigated and researched on non - loaded crack, especially those caused by thermal - shrink, and analyzed the thermal - shrink stress of beam, slab and continuous - wall, found that according data of civil and overseas offered thermal - shrink calculating formula without considering effect of factors, such as the cement quantity, using of aruhuesiru, aggregate size and quantity of sand, which made the result data smaller. in addition, there are not enough construct measure in code
本文對非荷載裂縫，特別是溫度?收縮裂縫進行了調查研究，並對兩端或四周約束的梁、板和底部約束的地下連續墻進行了收縮應力分析，發現國內外有關文獻給出的收縮計算公式沒有考慮泵送商品混凝土的水泥用量、外加劑使用、骨料粒徑和砂用量等因素的影響，計算出的混凝土收縮量往往偏小；另外， 《規范》中針對溫度?收縮裂縫的構造措施不足。In order to direct the water to the forebav of the pump station from the original canal, a channel long 135 m is designed. it crosses through the terrain top with a depth of more than 50 m. soil of the channel slopes is a strongly - weathered silty and sandy mudstone with many well - developed reticular cracks and takes the structural surfaces almost same as the channel slopes
東深供水工程金湖泵站位於塘廈鎮東面，屬低山、殘丘地貌，地面高程22 60m ；泵站前池進水渠橫切山脊，連接原東深供水河，設計開挖1條長135m的進水渠，坡高50多米，邊坡土質為強風化的粉砂質泥巖，網狀裂隙發育，結構面基本與坡面重合；坡體土質中含有較多的粘土礦物，具有遇水軟化的特性。Measures for further developing concrete mix design were presented based on above work. for example, adopts pfca as an index in designing durability of concrete, uses mortar slump flow test to select cements and water - reducers and to measure saturation dosage of water - reducer in mortar and then determine optimum dosage of it in concrete, uses bar - slump test to determine stability and fluidity of fresh concrete, and consequently, the workability of high fluidity and high stability concrete such as pumped or self - compacting concrete can be designed by adopting proper cfvm determined in terms of rheological properties of designed mortar measured with cone - based rheometer
如採用粗集料破碎率作為耐久性設計的一個指標；採用砂漿坍落擴展度試驗選擇水泥和減水劑，確定砂漿中減水劑的飽和摻量，並通過上述數學模計算混凝土中減水劑的飽和摻量，以此為參照確定最佳摻量；採用障礙坍落度試驗確混凝土的穩定性和流動性，結合由漏斗式砂漿流變儀測定的砂漿流變性能確定合理的砂漿填充系數，從而實現對高流動性高穩定性要求的混凝土（如泵送和免振自密實等）的工作性設計。
