It is understood that total length of 336 meters of the White Horse Gate River inverted siphon movements concrete pipe 200 meters, concrete pipe inverted siphon Body Overall width 33 meters, will need to install 3079.5 tons steel production, 33,137.5 cubic meters of concrete poured.

据了解，总长为336米的白马门河倒虹吸混凝土管身段200米，倒虹吸混凝土管身总宽33米，需要安装3079.5吨钢筋制作，混凝土浇筑33137.5立方米。

Traditional block has the construction requirements of constructional column, tensile inarch bar, castinplace concrete ring beam, and it is diffic ul t for construction and to assure the construction quality, moreover, the period is long. However, the core column and beam of new concrete hollow block with mac roporous lightweight aggregate adopt Ushape block to instead of traditional te c hniques. This technology reduces the process of formwork and binding reinforceme nt, and has the characteristics of convenient operation, rapid construction spee d, strong crack resistance, lower cost, and good insulation properties, and so o n.

摘要］ 传统的砌块有构造柱、拉结筋、现浇混凝土圈梁等施工要求，施工难度大、施工工期长、且施工质量不容易得到保证；新型材料大孔轻集料混凝土空心砌块芯柱以及芯梁采用 U形砌块代替传统工艺要求，减少了支模、绑扎钢筋等工序，还具有使用方便，施工速度快，抗裂性强、节约成本、保温绝热性能好等施工优点。
