港珠澳大桥沉管隧道工程需对海中隧道基槽抛填10~100 kg块石，并通过水下夯平增加基床的密实度，提高沉管基础的承载力，然后进行碎石垫层铺设及沉管沉放对接安装。文中详细介绍了抛石夯平设备的工作原理和节能技术，为类似的深海地基处理工程提供借鉴。

항주오대교침관수도공정수대해중수도기조포전10~100 kg괴석，병통과수하항평증가기상적밀실도，제고침관기출적승재력，연후진행쇄석점층포설급침관침방대접안장。문중상세개소료포석항평설비적공작원리화절능기술，위유사적심해지기처리공정제공차감。
The Hongkong-Zhuhai-Macao Bridge immersed tube tunnel engineering needs to throw fill the underwater tunnel joint grooves with 10 kg to100 kg of stone, and through the underwater ram flat to increase the compactness of bedding, improving the bearing capacity of immersed tube foundation, and then paving the rubble cushion and sinking and jointing the immersed tube. We introduced the operation principle and energy saving technology of riprap tamping equipment, which can provide references for similar deep seabed foundation treatment projects.
