无盖重结合异孔引管混凝土盖重固结灌浆方法
摘要：
本发明涉及一种无盖重结合异孔引管混凝土盖重固结灌浆方法。本发明的目的是提供一种无盖重结合异孔引管混凝土盖重固结灌浆方法，旨在避免传统固结灌浆方式在二次扫孔后发生浆液堵塞孔壁的情况，加大基础表层岩体补强灌浆压力，从而显著提高表层基础固结灌浆质量。本发明的技术方案是：无盖重结合异孔引管混凝土盖重固结灌浆方法，具有大坝基础和其表面基本平整的大坝基础面，该大坝基础从大坝基础面向下依次分为表层岩体段和搭接段；大坝基础面上部为待浇筑的混凝土结构，分两个阶段处理大坝基础。
摘要（英）：

The invention relates to a concrete cover-weight consolidation grouting method for non-cover-weight combination of different holes through guide pipes. The invention aims at providing the concrete cover-weight consolidation grouting method for non-cover-weight combination of the different holes through the guide pipes, avoiding a condition that grout blocks hole walls after secondary hole cleaning by a conventional consolidation grouting method, and enhancing the reinforcement grouting pressure of a foundation surface-layer rock mass, so that the surface-layer foundation consolidation grouting quality can be substantially improved. The technical scheme provided by the invention is that a dam is provided with a dam foundation and a dam foundation surface basically flush with the surface of the dam foundation, the dam foundation sequentially comprises a surface-layer rock mass segment and a lapping segment from the dam foundation surface to the bottom, the upper portion of the dam foundation surface has a concrete structure to be poured, and the concrete cover-weight consolidation grouting method for non-cover-weight combination of the different holes through the guide pipes comprises two stages to process the dam foundation.
