Foundation pit side slope Larsen steel sheet pile reinforcing construction method
The embodiment of the invention discloses a foundation pit side slope Larsen steel sheet pile reinforcing construction method. The foundation pit side slope Larsen steel sheet pile reinforcing construction method comprises the following steps of side slope toe backfilling and back pressing, concrete slab grooving, steel plate pile driving and reinforcing, steel plate pile top channel steel top beam welding, concrete top beam pouring and backfilling grooving, slope toe earthwork layered excavation, concrete hanging plate layered construction, inner support top beam earthwork excavation, top beam and inner support and steel plate pile pulling out. The method is advantaged in that a slope support is reinforced, a problem that the Lassen steel sheet pile is difficult to construct near a silt layer is solved, and potential safety hazards are avoided.
本发明实施例公开一种基坑侧边坡拉森钢板桩加固施工方法，包括以下步骤：侧边坡坡脚回填反压→混凝土板剔槽→钢板桩打桩加固→钢板桩桩顶槽钢冠梁焊接→混凝土冠梁浇筑并回填剔槽→坡脚土方分层开挖→混凝土挂板分层施工→内支撑冠梁土方开挖→冠梁及内支撑→钢板桩拔出，本发明对边坡支护进行加固，解决了坡拉森钢板桩在淤泥层附近施工困难的问题，解决了安全隐患。
