32米预应力混凝土井架是一种带后撑式的矿井提升塔架,由立架、头部和后撑架三部分组成。天轮中心标高32米,采用以预应力钢筋兼作拼装手段的预应力混凝土结构。整个井架由一百零四块预制构件组成,除天轮梁与后撑架连接采用预埋件焊接及各预制块之间用少量供组装用的装配螺栓外,其余均通过预应力钢筋将这些预制块组成整体。
The 32-meter prestressed concrete derrick is a kind of mine lifting tower with rear support type, which consists of three parts: stand, head and rear support frame. The height of the center of the wheel is 32 meters high, and the prestressed concrete structure is also used as pre-stressed reinforcement. The entire derrick consists of 104 prefabricated components. Except for the connection between the sundial beam and the rear support frame, the pre-embedded parts are used for welding and a small amount of assembly bolts are used for assembly between the prefabricated blocks. The rest are all made of prestressed steel bars. The prefabricated blocks make up the whole.
