Deep foundation pit outer wall and diaphragm wall backfill tamping device and method
The invention provides a deep foundation pit outer wall and diaphragm wall backfill tamping device and method. The deep foundation pit outer wall and diaphragm wall backfill tamping device and method are used for tamping soil in a narrow and deeper backfill area between a building body and an enclosure wall layer by layer. In general, the device comprises a crane, a bearing bridge, an ejection device and a heavy hammer, the crane is located on the outer side of a foundation pit on the ground surface, the end of a suspension arm of the crane is located above a backfill area of the foundation pit, one end of the bearing bridge is fixedly arranged, the other end of the bearing bridge penetrates into the backfill area of the foundation pit, the ejection device is hung on the bearing bridge, and the heavy hammer is arranged on the lower side of the ejection device. A lifting rope of the lifting arm penetrates through the bearing bridge and the ejection device and then lifts the heavy hammer. According to the device and the method, a crane hoists the heavy hammer to move upwards and extrudes the ejection device, the ejection device accumulates force, and when hoisting power is cut off, the heavy hammer accelerates to fall under the gravity of the heavy hammer and the elastic force of the ejection device. The falling acceleration of the heavy hammer is compensated through the ejection device, the tamping force is larger, the tamping efficiency is higher, and the tamping density and consistency are controllable.
本发明提供一种深基坑外墙与地连墙回填打夯装置及方法，用于对位于建筑物本体和围护墙之间狭窄和较深回填区土体进行逐层夯实。概括来说，本装置包括吊车、承重桥、弹射装置和重锤，吊车位于地表的基坑外侧，吊车的吊臂端部位于基坑的回填区上方，承重桥的一端固定设置，另一端深入基坑的回填区，弹射装置悬挂在承重桥上，重锤设置在所述弹射装置的下侧，吊臂的吊绳穿过承重桥和弹射装置后，吊住重锤。本装置及方法配合工作，吊车吊起重锤上移并挤压弹射装置，弹射装置蓄力，当起吊动力切断时，重锤在自身重力和弹射装置的弹力下加速坠落。通过弹射装置对重锤的下坠加速度补偿，夯实力度更大、夯实效率更高、夯实密度大小和一致性可控。
