Totally-closed continuous construction method for core wall area of gravelly soil core wall rock-fill dam
The invention discloses a full-closed continuous construction method for a core wall area of a gravelly soil core wall rock-fill dam. Comprising the steps that an inflatable ceiling is arranged above a core wall area of the gravelly soil core wall rock-fill dam, the edges of the inflatable ceiling are fixed to the two banks, an upstream rock-fill area and a downstream rock-fill area, at least a core wall filling area is located in an inflatable ceiling covering area, and the edges of the inflatable ceiling are sealed; and an air supply device is adopted to supply air into the inflatable ceiling, the pressure intensity of the inner side of the inflatable ceiling is larger than the external pressure intensity, the inflatable ceiling is supported, a closed construction space is formed, and the height of the closed construction space is larger than the preset height of the core wall of the gravelly soil core wall rock-fill dam in the construction period. The inflatable ceiling is made of the base cloth, the steel cable net is arranged above the inflatable ceiling, the core wall filling area is covered and wrapped in the two banks and the upstream and downstream rockfill areas, the air supply device is adopted for supplying air to the inner side of the inflatable ceiling to support a closed space for shielding wind, rain and heat, and normal construction can still be conducted in winter and rainy seasons; and annual continuous safe construction is realized.
本发明公开了一种砾石土心墙堆石坝心墙区全封闭连续施工方法。包括在砾石土心墙堆石坝心墙区上方布置充气顶棚，将充气顶棚的边缘固定在两岸、上游堆石区和下游堆石区，至少使心墙填筑区域位于充气顶棚覆盖区域内，并将充气顶棚边缘密封；采用供风装置向充气顶棚内供风，使充气顶棚内侧的压强大于外部压强，将充气顶棚撑起，形成封闭的施工空间，封闭的施工空间高度大于施工本期砾石土心墙堆石坝心墙预定高度。本发明采用基布制成搭建充气顶棚并在上方布置钢索网，在两岸和上下游堆石区将心墙填筑区覆盖包裹在内，采用供风装置向充气顶棚内侧供风撑起一个遮风避雨和保暖的封闭空间，在冬季和雨季仍然可以正常施工，实现全年连续安全施工。
