在修作虹吸管圬工部分,有一件工程是可以改变以下设计的:根据需要它仅是一个重座(如图1)原计划是用110号混凝土打成,内有受拉力铁件(每根管子两个)平均每根虹吸管长有3.5公尺,断面1.5公尺,方形。但是根据需要与所受的拉力及建筑物本身重量并参照已经修建的虹吸管效果来看(刘家夹河、路家庄),是完全可以不用110号混凝土而改用100号水泥沙浆砌乱石(如图2)的,这在施工中除加强铁件周围注意留有楔 In the siphon section, there is one project that can be changed in the following designs: it is just a heavy block as required (see Figure 1). The original plan was to use 110 concrete, with tensioned iron pieces (each pipe Sub two) On average, each siphon pipe has a length of 3.5 meters and a cross section of 1.5 meters square. However, according to the needs and the tension suffered and the weight of the building itself and with reference to the siphon effect has been built (Liu Jia Jia, Lujiazhuang), is not possible to use concrete instead of No. 110 cement mortar mess 100 (Figure 2), which in addition to construction in the vicinity of iron to keep wedges attention
