Spillway tunnel bottom plate construction method
The invention provides a spillway tunnel bottom plate construction method. The spillway tunnel bottom plate construction method comprises the following steps that underground earthwork is gradually excavated in a target area section by section to form a plurality of linear tunnel sections and a plurality of bent tunnel sections, all the linear tunnel sections and all the bent tunnel sections are finally communicated in sequence according to the excavation sequence to form a spillway tunnel, meanwhile, bottom plate units are built in a segmented mode in sequence in the extending direction of the spillway tunnel, all the bottom plate units are finally and sequentially connected according to the building sequence to form the spillway tunnel bottom plate, and when the bottom plate units are located in the linear tunnel sections, the corresponding bottom plate units are shorter than 8m, and when the bottom plate units are located in the bent tunnel sections, the corresponding bottom plate units are shorter than 4m. By the adoption of the technical scheme, disturbance to surrounding rock of the spillway tunnel is reduced, the surrounding rock is reinforced in time, water seepage is effectively prevented by excavating the spillway in a segmented mode, building the bottom plate units in a segmented mode and pouring concrete in a layered mode, and the safety protection performance is enhanced by building side wall units on the left sides and the right sides of the bottom plate units; and the concrete engineering construction quality is improved.
本发明提供一种溢洪洞底板施工方法，包括以下步骤：在目标地区分段逐次挖掘地下土石方形成多个直线洞段和多个弯曲洞段，所有直线洞段、弯曲洞段最终按照挖掘先后顺序依次连通组成溢洪洞，同时，沿着溢洪洞延伸方向分段逐次修筑底板单元，所有底板单元最终按照修筑先后顺序依次连接组成溢洪洞底板，并且当处于直线洞段时，相应的底板单元长度小于8m，当处于弯曲洞段时，相应的底板单元长度小于4m。采用本发明的技术方案，通过分段挖掘溢洪洞、分段修筑底板单元并分层浇注混凝土，减少了对溢洪洞围岩的扰动，及时对围岩进行加固，有效防止渗水，还通过在底板单元左右两侧修筑边墙单元，加强了安全防护性，提升了混凝土工程施工质量。
