1工程概况浏河大桥全长412m,其中主桥段分为3跨,跨径均为42m,采用节段预制拼装工艺。每跨箱梁划分为13个节段,分为标准块、端块和转向块3种。其中,端块长2.7m,标准节段和转向块节段为3.33m,每个节段重35～40t。端块设置端横梁,作为预应力束锚固端;转向块设有体外束转向构造。箱
1 Project Overview The Liuhe Bridge is 412m long, of which the main bridge is divided into 3 spans and the span is 42m. The prefabricated assembly process is adopted. Each cross-box girder is divided into 13 segments, divided into three kinds of standard blocks, end blocks and steering blocks. Among them, the end block length 2.7m, the standard segment and the steering block segment is 3.33m, each segment weighs 35 ~ 40t. The end block is provided with an end cross beam as an anchorage end of the prestressed beam; the steering block is provided with an external beam steering structure. box
