Repairing and strengthening method suitable for foundation destroyed blocky wharf
The invention discloses a repairing and strengthening method suitable for a foundation destroyed blocky wharf. The repairing and strengthening method comprises the following steps of 1, piling backpressure geotextile bags on the front side of the wharf; 2, drilling a sand well on the outer side of a backpressure geotextile bag pile, and conducting drainage consolidation on a foundation; 3, dismantling the backpressure geotextile bag pile in a segmented after foundation settlement is stabilized, driving a row of cast-in-place piles I synchronously in a segmented mode, driving the cast-in-placepiles I to pass through the bottom of a wharf apron of a destroyed segment of the wharf, driving two rows of cast-in-place piles II close to the wharf apron on the two sides of the destroyed segment of the wharf correspondingly; 4, injecting prepacked aggregate concrete to a foundation bed; 5, conducting back pressing on the front side of the wharf to form a permanent back pressure structure; 6, leveling a breast wall by embedding bars on the outer side, and supporting the bottom of a breast wall leveling structure onto the cast-in-place piles I; and 7, leveling the wharf surface through repatching. Through the repairing and strengthening method suitable for the foundation destroyed blocky wharf, the appearance of the wharf can be recovered, the functions of ship berthing and cargo loadingand unloading can be achieved, the foundation can be strengthened, the structure stability is improved, and the method has the obvious economic efficiency and environmental friendliness.
本发明公开了一种适用于地基破坏后块体码头的修复加固方法，采用以下步骤：1)在码头前侧堆砌反压土工袋；2)在反压土工袋堆垛外侧打设砂井，对地基进行排水固结；3)在地基沉降稳定后，分段拆除反压土工袋堆垛，并同步分段打设一排灌注桩Ⅰ，灌注桩Ⅰ贯穿码头破坏段的前沿底部；在码头破坏段两侧，各打设一排靠近码头前沿的灌注桩Ⅱ；4)进行基床升浆；5)在码头前侧进行反压，形成永久反压结构；6)通过外侧植筋找平胸墙，胸墙找平结构的底部支撑在灌注桩Ⅰ上；7)通过修补找平码头面。本发明既能恢复码头外观，又可以满足船舶靠泊及货物装卸使用功能，还可以加固地基，增大结构稳定性，具有明显的经济性和环境友好性。
