Wet and soft soil foundation self-drainage dynamic compaction treatment method and self-drainage dynamic compaction equipment
The invention discloses a wet and soft soil foundation self-drainage dynamic compaction treatment method and self-drainage dynamic compaction equipment. The wet and soft soil foundation self-drainage dynamic compaction equipment comprises a rammer and a lifting device, ramming plates are arranged at the bottom of the rammer at intervals, elastic reset pieces are connected between the ramming plates and the rammer, and protective cylinders are fixedly connected to the peripheral sides of the ramming plates; a plurality of water permeable holes are formed in the tamping plate in a penetrating mode, an impact-resistant filtering mechanism is arranged on the side, away from the rammer, of the tamping plate, and the tamping plate is provided with a backflow preventing structure at the water permeable holes. A water storage tank is formed in the bottom of the rammer, a piston is slidably arranged in the water storage tank, a water drawing pipe with one end extending to be connected with the ramming plate and the other end communicating with a cavity of the water storage tank is fixedly connected to the piston, and a plurality of water drawing holes are formed in the peripheral side of the end, close to the ramming plate, of the water drawing pipe; the rammer is provided with an outer drainage mechanism which is communicated with the cavity in the bottom wall of the water storage tank and prevents fluid from flowing back into the water storage tank. The automatic water pumping and draining effect can be achieved in the dynamic compaction process, the water draining pipe does not need to be lowered after hammer stopping, the construction steps are reduced, and the construction efficiency is improved.
本申请公开了一种湿软土地基自排水强夯处理方法及自排水强夯设备，其包括夯锤、起吊装置，夯锤底部间隔设有夯击板，夯击板与夯锤之间连接有弹性复位件，夯击板周侧固接有防护筒；夯击板上贯穿开设有多个透水孔，夯击板远离夯锤的一侧设置有耐冲击过滤机构，夯击板于透水孔处防倒流结构；夯锤底部开设有储水槽，储水槽内滑动设置有活塞，活塞上固接有一端延伸至与夯击板连接、另一端与储水槽空腔连通的汲水管，汲水管靠近夯击板一端的周侧开设有多个汲水孔；夯锤上设置有与储水槽槽底壁处空腔连通且避免流体倒流至储水槽中的外排水机构。本申请具有能在强夯过程中实现自动抽排水效果，无需停锤后再下放排水管，缩减了施工步骤，提高了施工效率。
