摘　　要：为解决深基坑施工中因肥槽宽度狭小、无法在肥槽范围内搭设落地式马道的问题,特研制了悬挂式马道。悬挂马道采用钢结构设计,其利用三角托架作为承重结构,将荷载通过三角托架传递至支护桩,从而解决了深基坑施工时人员进出场的问题。应用实践证明:该马道具有占地面积小、安拆方便、行走便利、周转使用次数多等优点,可在场地受限的深基坑施工中推广使用。In order to solve the problem that the bench width is too narrow to set up a grounded bench, a suspended bench has been particularly developed. Such suspended bench adopts the steel structure design, which used the triangular bracket as the load-bearing structure and transmits the load to the supporting pile through the triangular brackets, thereby solving the problem of personnel entering and leaving the deep foundation pit during construction. The applied practice has proved that the suspended bench has the advantages of small floor area, convenient installation and disassembly, convenient walking and more turnovers, and can be widely used for the construction of deep foundation pit on limited jobsite.
