水电工程高边坡无排架快速支护施工技术

Rapid Support Construction Technology for High Slope Without Scaffolding in Hydropower Engineering

结合以往水电工程高边坡施工经验,受边坡开挖分层高度限制,边坡支护主要采用搭设施工排架作为平台进行施工,边坡深层锚索支护受施工排架搭设慢、常规材料待强影响,施工工序难以有效衔接,边坡支护的及时性难以保证,对边坡稳定及施工安全不利,进而制约边坡施工进度。TB水电站尾水出口边坡支护投入性能优良的施工设备、采用新型早强材料、优化施工工艺,实现了高边坡无排架、快速施工,确保了高边坡的整体稳定。

Based on previous experience in high slope construction of hydropower projects,due to the height limitation of slope excavation layers,slope support mainly adopts the construction of scaffolding as a platform for construction.The deep anchor cable support of slopes is affected by slow construction scaffolding and weak conventional materials,making it difficult to effectively connect the construction process.The timeliness of slope support is also difficult to ensure,which is detrimental to slope stability and construction safety,thereby restricting the progress of slope construction.The construction equipment with excellent performance,the use of new early strength materials,and optimized construction technology for the slope support of the tailwater outlet of TB hydropower station have achieved high slope without scaffolding and fast construction,ensuring the overall stability of the high slope.
