Rock anchor beam structure, underground powerhouse structure and construction method of underground powerhouse structure
The invention discloses a rock-anchored beam structure, an underground powerhouse structure and a construction method of the underground powerhouse structure. The problems that in the prior art, rock-anchored beam construction efficiency is low, and disturbance to peripheral rock walls is large are solved. The rock-anchored beam structure comprises a beam body, and the outer side face of the beam body is an arc-shaped face. Preferably, the inner side face of the beam body comprises a top plane and an inner side vertical face, the upper portion of the arc-shaped face is connected with the top plane, and the lower portion of the arc-shaped face is connected with the inner side vertical face through a bottom inclined face. The underground powerhouse structure comprises the rock-anchored beam structure. Upper side walls are connected to the upper portions of the rock-anchored beam structures, lower side walls are connected to the lower portions of the rock-anchored beam structures, and a dome structure stretches across the two upper side walls. In underground powerhouse construction, a heading machine is adopted to construct the rock-anchored beam, a one-side arc-shaped structure is formed, and surrounding rock disturbance at the rock-anchored beam position is reduced; a pre-splitting blasting mode is adopted for the side wall at the bottom of the rock-anchored beam, the rock mass around the rock-anchored beam can be protected through the mode that the position of the rock-anchored beam is excavated through the TBM and the pre-splitting blasting mode is adopted for the bottom of the rock-anchored beam, and construction disturbance is avoided; the construction efficiency is improved, and the construction period of the underground powerhouse can be greatly shortened.
本发明公开了一种岩锚梁结构、地下厂房结构及其施工方法，解决了现有技术中岩锚梁施工效率低，对周边岩壁扰动大的问题。本发明岩锚梁结构，包括梁体，梁体的外侧面为弧形面。作为优选，所述梁体的内侧面包括顶平面和内侧竖直面，弧形面的上部与顶平面相连接，弧形面的下部通过底斜面与内侧竖直面相连接。地下厂房结构，包括所述的岩锚梁结构；岩锚梁结构的上部连接有上边墙、下部连接有下边墙，两个上边墙之间横跨设有穹顶结构。本发明地下厂房施工中采用掘进机施工岩锚梁，形成一侧弧形结构，减少岩锚梁位置处的围岩扰动；岩锚梁底部边墙采用预裂爆破方式，通过TBM开挖岩锚梁位置及岩锚梁底部预裂爆破的方式可保护岩锚梁周边岩体，避免施工扰动；提高了施工效率，可极大缩减地下厂房的施工工期。
