啟動電機帶動油泵運轉，液壓油直接返回油箱手動轉動換向閥三位四通閥一個位置后，液壓油進入系統推動活塞，活塞桿伸出，帶動鉗體收縮，從而破碎鋼筋混凝土結構，反向轉動換向閥，鉗體松開，完成一個工作循環。Fabrication of the box beam is divided into such parts as reinforcement, formwork, concreting, prestressing, moving and storing of beam, pipe grouting under pressure, end sealing of the beam, water - proof layer on the bridge surface system, protective coating etc. the paper makes description of effective box beam construction technology and workmanship which can be adopted in other projects, such technologies as : manufacturing and fixing of reinforcement, steel reinforcement fixing baseplate, web plate and top plate respectively and lifting the steel skeleton into form, requirements of design and manufacturing and way of utilization for dismantling - erection type formwork and hydraulic formwork, optimization of concrete ratio, concrete pouring process of two ends of beam in priority over the middle, in sequence of first baseplate followed by web plate and top plate at last, concrete pouring in inclined section and in horizontal layer, concrete vibration mainly by external vibrator in assistance with internal vibrator, methods and regulation for steam curing of concrete, dual controls over stress and strain to ensure quality of prestressing workmanship, construction method of effective beam moving by heavy - weight special moving facility, some regulations and key notes about construction of grouting under pressure, beam ends sealing, water - proof layer on the bridge surface system, protective coating
箱梁製造由鋼筋工程、模板工程、混凝土工程、預應力工程、移存梁工程、孔道壓漿工程、梁體封端工程、橋面防水層和保護層工程等施工環節組成。文中介紹的採用胎具製作和綁扎鋼筋，分底腹板和頂板分別綁扎並吊裝鋼筋骨架入模；拆裝式和液壓式兩種模板的設計、製作要求和使用方法；綜合考慮、優化混凝土配合比，混凝土灌注從兩端至中間、先底板、后腹板、再頂板的施工順序和斜向分段、腹板水平分層、附著式振搗為主、插入式搗固為輔的施工工藝，蒸汽養護的方法和規定；應力應變雙控制確保預應力施工質量的施工技術；採用重物移運器有效移梁的施工方法；壓漿、封端、橋面防水層和保護層施工的一些規定和注意事項等都是對箱梁製造行之有效的施工技術和施工方法，並可為以後類似施工作借鑒。In order to ascertain stress behavior of steel lined reinforced concrete pipe accurately, according to the fundamental principle of non - linear computation of reinforced concrete elements, the steel lined reinforced concrete penstock on downstream dam surface in a hydropower station is calculated and analyzed, and the distribution of circumferential stress of the steel lined reinforced concrete pipe is obtained, it proves that it is safe and reasonable to use structures of steel lined reinforced concrete penstock in hydroelectric station construction, and can satisfy the requirement of project
摘要為了能夠準確地把握鋼襯鋼筋混凝土管的受力性能，根據鋼筋混凝土單元非線性計算的基本原理，對某水電站鋼襯鋼筋混凝土壩後背管進行了計算分析，得出了鋼襯鋼筋混凝土管環向應力的分佈情況，分佈情況說明了此水電站採用鋼襯鋼筋混凝土壩後背管的結構形式是安全合理的，可以滿足工程要求。The mechanism of reinforcing steel bar under the press or pull is researched and the characteristics under the pull - press cyclic loading is studied in composite foundation. it shows that the stress concentrating on the reinforcing steel bar and the increasing stress can be seen with the increasing of cyclic times. residual strain always exists after unloading without considering the size of pullout force and increases slowly with the cyclic times
探討了復合地基中抗拔鋼筋的受壓受拉機理及在拉壓循環荷載作用下的性狀，研究發現，隨拉壓循環次數的增加，應力向鋼筋集中，鋼筋承受的壓力隨著增大；無論上拔力大小，卸載后都有殘余變形，並隨著拉拔循環次數的增加而緩緩增加；抗拔碎石樁破壞性狀明顯，可明確的得到抗拔碎石樁的破壞荷載。分享友人
