Movable construction platform for rock-anchored beam of underground powerhouse
The invention discloses a movable construction platform for a rock-anchored beam of an underground powerhouse. The movable construction platform comprises a first movable track and a steel platform structure, the first moving track is arranged on the rock anchor beam and drives the steel platform structure on the first moving track to move through the electric chain block; the steel platform structure comprises a steel platform main beam arranged on the first moving track, and a grid-shaped steel platform secondary beam is arranged above the steel platform main beam; the two tensioning cages are overhung on the left side and the right side of the steel platform main beam, the second moving track is arranged on the steel platform structure, and a movable suspended ceiling construction platform is further arranged on the second moving track; according to the construction method, anchor cable construction is conducted synchronously through the movable platform, the construction method that a middle pilot tunnel is conducted in advance, and left and right side walls are excavated in a staggered mode can be adopted for bottom excavation, the principle of plane multi-procedure, three-dimensional multi-layer, layered excavation and layer-by-layer supporting is followed, traditional single-plane construction is converted into multi-space construction, and the construction efficiency is improved. And the limited construction space is fully utilized to a great extent.
本发明公开了一种地下厂房岩锚梁可移动施工平台，包括第一移动轨道、钢平台结构；第一移动轨道设置于岩锚梁上，并通过电动倒链带动第一移动轨道上的钢平台结构移动；钢平台结构包括设置于第一移动轨道上的钢平台主梁，在钢平台主梁的上方设有栅格状的钢平台次梁；还包括悬挑于钢平台主梁左右两侧的两个张拉吊笼及设置于钢平台结构上的第二移动轨道，在第二移动轨道上还设有可移动的吊顶施工平台；本发明利用移动平台同步进行锚索施工，底部开挖可采用中导洞先行，左右两侧边墙错距开挖的施工方法，遵循“平面多工序、立体多层次、分层开挖、逐层支护”的原则，将传统的单一平面施工转换为多空间施工，极大程度地对有限的施工空间进行充分利用。
