1 引言 作为防浪堤、护岸等工程基础的堆石构筑的堤坝是采用抛投石块,然后使石块压实平整来完成的。近年来,由于潜水人员年龄大、数量少等原因,采用潜水人员操作压实作业的大型、大水深工程遇到了很大困难,尤其是海洋工程上迫切要求进行机械化施工。目前,在基础实验的基础上,已完成了在堆石堤上进行摊铺压实作业的座式夯锤摊铺压实机的开发。本文主要介绍该机,还列举了它在大阪港海底隧道南港换气站基础工程(施工水深33m)等施工上取得的良好应用实绩。2 主要技术参数 该机从母船(LETS-1号船)吊降到堆石堤上,座落在堆石堤上进行堆石摊铺,根据需
1 Introduction As a breakwater, bank protection and other projects based on the rockfill dam construction is the use of throwing stones, and then make the stone compaction formation to complete. In recent years, due to the age of scuba divers and the small number of them, it is very difficult for large-scale and large-scale deep-water projects that employ divers to operate compaction operations, especially for offshore engineering. At present, based on the basic experiment, the development of the bench-type rammer paving and compacting machine for paving and compaction on the rockfill bank has been completed. This article mainly introduces the aircraft, but also lists its good application performance in the construction of Nankang ventilation station of Osaka Harbor Crossing (construction depth 33m). 2 The main technical parameters of the aircraft from the mother ship (LETS-1) hanging down to the rockfill, located on the rockfill embankment for rockfree paving, according to need
