The phenomena can be observed in the tests low seepage pressures can easily form passageways behind the waterproof layer if there is no drainage layer or the drainage layer is blocked in the single - shell test slab ; the waterproof layer can resist higher seepage pressure if there is no drainage layer or the drainage layer is blocked in the double - shell test slab ; the seepage water can be controlled and drained away in the drainage layer by the water proof layer only if there is unblocked drainage layer behind it in the double - shell test slab
由試驗可見，在單層試驗板中沒有排水層或排水層不通暢時，較低的水壓就能在防水膜后形成滲流通路；在雙層試驗板中沒有排水層或排水層不通暢時，防水膜能抵抗一定程度的滲漏水壓；只有在雙層試驗板中的排水層暢通時，防水膜才能有效地將滲漏水控制在排水層中排走。 -

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 our country, most of bridges were built in 1960s or 1970s, which were based on that time traffic discharge and development planning, so design criterion of these bridges were very lower. in addition, it was inevitable to bring about cracks > concrete rupture, steel rust ^ honeycomb and water proof layer failure, because some established bridges were built by poor construction and maintenance during the course of operating period. all above mentioned lead to durability and bearing capacity could n ' t gain to design standard
由於我國很多橋梁建於上個世紀六、七十年代，基於當時的車流量和各方面的發展規劃，橋梁設計等級普遍偏低；另外，某些既有橋梁由於施工質量差和運營期間維護不到位，不可避免地會產生裂縫、混凝土破損、鋼筋銹蝕、蜂窩及防水層失效等缺陷，從而導致耐久性及承載力達不到設計要求。
