Construction method of bridge pile foundation close to metro section
The invention discloses a construction method of a bridge pile foundation close to a subway section, and relates to the field of bridge pile foundation construction. Comprising the following steps that a plurality of reinforcing holes are formed in the periphery of a pile hole, filling materials are added into the reinforcing holes, and the filling materials are tamped; anti-sinking grouting holes are drilled in the bottoms of the pile holes, and concrete is poured into the anti-sinking grouting holes in a pressurized mode; and more than two protective grouting holes are drilled in the area, located between every two adjacent reinforcing holes, around the pile hole, and concrete is poured into the protective grouting holes in a pressurized mode. A plurality of reinforcing holes are formed in the periphery of a pile hole, filling materials are tamped in the reinforcing holes, anti-sinking grouting holes are drilled in the bottom of the pile hole, concrete is poured into the anti-sinking grouting holes in a pressurized mode, protective grouting holes are drilled in the periphery of the pile hole, and concrete is poured into the protective grouting holes in a pressurized mode. And the soil body around the bridge pile foundation is reinforced, and the situation that the soil body settles, and consequently the safety of a subway section is affected is avoided.
本发明公开了一种紧临地铁区间桥梁桩基的施工方法，涉及桥梁桩基施工领域；包括以下步骤：在桩孔位置四周开设多个加固孔，向加固孔内添加填充材料，对填充材料进行夯实；在桩孔的底部钻设防沉灌浆孔，在防沉灌浆孔内加压灌入混凝土；在桩孔位置周围且位于相邻两个加固孔之间的区域钻设两个以上防护灌浆孔，在防护灌浆孔内加压灌入混凝土。本发明通过在桩孔位置四周开设多个加固孔并在加固孔内夯实填充材料、在桩孔的底部钻设防沉灌浆孔并在防沉灌浆孔内加压灌入混凝土、在桩孔位置周围钻设防护灌浆孔并在防护灌浆孔内加压灌入混凝土，使得桥梁桩基周围的土体得到了加固，防止了土体沉降进而影响地铁区间安全的情况发生。
