Stilling pool tail sill protection structure and construction method
The invention discloses a stilling pool tail sill protection structure and a construction method, and belongs to the technical field of water conservancy and hydropower engineering. A stilling pool tail sill protection structure comprises a stilling pool tail sill formed by an original downstream cofferdam, a protection structure on the upstream side of the downstream cofferdam and a protection structure on the downstream side of the downstream cofferdam. The protection structure on the upstream side of the downstream cofferdam comprises a ground beam arranged on a slope toe, multiple layers of lead wire cages stacked on the inner side of the ground beam, a block stone protection slope located on the back faces of the lead wire cages and a lead wire cage protection part formed by building block stones after the lead wire cages are stacked to the top of the cofferdam. According to the method, the original downstream cofferdam dismantling work amount is reduced, and the stilling pool tail sill concrete pouring work amount is saved; lead wire gabions, block stone slope protection and mortar pouring building are adopted, and the stability and impermeability of the stilling pool tail sill after protection are guaranteed; operation is convenient and easy, and rapid construction is achieved on the premise that safety and quality are guaranteed; construction cost is reduced and construction period is saved.
本发明公开了一种消力池尾坎防护结构及施工方法，属于水利水电工程技术领域；一种消力池尾坎防护结构，包括：由原下游围堰形成的消力池尾坎，以及下游围堰上游侧的防护结构、下游围堰下游侧的防护结构；其中：所述下游围堰上游侧的防护结构，包括：在坡脚设置的地梁，在地梁内侧码放的多层铅丝笼，位于铅丝笼背面的块石护坡，以及铅丝笼码放至围堰顶部后，由大块石砌筑形成的铅丝笼防护。本发明，减少原下游围堰拆除工程量，节约了消力池尾坎混凝土浇筑工程量；采用铅丝石笼+块石护坡+砂浆灌砌，保证消力池尾坎防护后的稳定和抗渗性；操作方便、简单，在确保安全、质量的前提下实现快速施工；降低施工成本，节约工期。
