Hydropower plant rock-anchored beam excavation method
The invention discloses a hydropower plant rock-anchored beam excavation method, which belongs to the technical field of hydropower engineering construction, and comprises the following steps: according to the size, shape and construction condition judgment of a rock-anchored beam, selecting excavation construction along a direction vertical to the rock-anchored beam or excavation construction along a direction parallel to the rock-anchored beam; the excavation construction in the direction perpendicular to the rock-anchored beam comprises the following steps that S110, rock-anchored beam vertical hole excavation is conducted, and drilling equipment is used for drilling and grooving of the vertical hole in the perpendicular direction of the rock-anchored beam; s120, rock-anchored beam inclined hole excavation is carried out, and inclined holes are drilled along a specific angle according to design requirements; and S130, the rock at the rock-anchored beam is subjected to block deslagging, the rock-anchored beam is cut off in a block mode, the rock is peeled off, and deslagging treatment is conducted. The method has the advantages that the labor intensity and danger of manual construction are reduced, the influence of blasting impact on the stability of the large underground cavern and the adjacent engineering is reduced or eliminated, and the construction precision is improved.
本发明公开了一种水电厂房岩锚梁开挖方法，属于水电工程施工技术领域，其包括如下步骤：根据岩锚梁的尺寸和形状及施工条件判断，选择使用沿垂直岩锚梁方向开挖施工或者沿平行岩锚梁方向进行开挖施工；沿垂直岩锚梁方向开挖施工包括如下步骤：S110，岩锚梁竖向孔开挖，使用钻孔设备沿岩锚梁的垂直方向进行竖向孔的钻孔成槽；S120，岩锚梁斜向孔开挖，按照设计要求沿特定角度钻斜向孔；S130，岩锚梁处岩石分块出渣，对岩锚梁进行分块切断，使岩石剥落并进行出渣处理。本申请具有降低人工施工的劳动强度和危险性，降低或消除爆破冲击对大型地下洞室及其邻近工程的稳定性的影响，提升施工精度的优点。
