我单位承建的某选煤厂主厂房至块精煤装车仓栈桥,为两段30m跨和一段25m跨的钢结构,采用钢筋混凝土框架梁柱,支座标高分别为16.300～24.600m、25.100～32.500m、34.300～40.500m。由于生产工艺改进,需要在原设计栈桥上增加钢桁架一层,框架梁柱从基础开始加大加厚,采用植筋工艺,
The main workshop of a coal preparation plant contracted by our unit is a two-stage 30m span steel bridge and a section of 25m span steel structure. The reinforced concrete frame beam and column are used with the support elevation of 16.300 ~ 24.600m and 25.100 ~ 32.500m, 34.300 ~ 40.500m. Due to the improvement of production technology, it is necessary to add a layer of steel truss on the original design trestle, the frame beam and pillar should be enlarged and thickened from the foundation,
