<< review queue entry 64223 - submitted by 'sl89' >> * I'm not convinced 沉井 refers specifically to open caissons. I can find Chinese definitions online that refer clearly to an open caisson (e.g. 沉井(open caisson) 上端无盖、下端无底、沉入岩土或水下作为施工护壁用的筒形结构。), but most dictionary definitions could describe any caisson. 【Wikipedia】 An open caisson is similar to a box caisson, except that it does not have a bottom face. It is suitable for use in soft clays (e.g. in some river-beds), but not for where there may be large obstructions in the ground. https://en.wikipedia.org/wiki/Caisson_(engineering)#Open 【百度百科】 沉井是井筒状的结构物，它是以井内挖土，依靠自身重力克服井壁摩阻力后下沉到设计标高，然后经过混凝土封底并填塞井孔，使其成为桥梁墩台或其它结构物的基础。 https://baike.baidu.com/item/%E6%B2%89%E4%BA%95/10445390 【Wenlin】 n. open caisson 【Pleco】 NOUN ARCHITECTURE open caisson 【LAC】 〖陆〗一种由钢筋混凝土构筑的筒状物，以作为地面下或水面下施工时的辅助设施。 【规范】 名 一种井筒状的钢筋混凝土构筑物, 是地下或水下施工时的辅助设施。 就每个沉井而言，未说清楚是集中进行一次性爆破，还是对1米高的分段进行多次爆破。 It is not clear if the blasting, for each caisson, is all to be carried out in one single blast or multiple blasts of the1 m high segments. 沉井以上的塔柱高度为170英尺. The towers are 170 ft above the caisson. 沉井施工技术在工业与民用建筑、公路、桥梁等专业的应用较为广泛，在水利水电施工中较为少见。 Open caisson well construction technology is widely used in industrial and civil structures, highways, bridges etc. , but comparably less in water conservancy and hydropower project. ----------------------------------- Editor: It makes sense that the word for "box caisson" would use the character for box: 沉箱. And that the word for "open caisson" would use the character for a well (井), since a well is usually open at both ends. |
