摘要

为解决某在建巨型单跨地下洞库被覆结构钢筋绑扎量大、混凝土浇筑量大、施工风险高，简易台架结构复杂、体型巨大、移动困难、施工效率低等技术难题，融合全液压钢模板衬砌台车与模块化高性能贝雷架的技术优点，研制集钢筋绑扎、混凝土浇筑功能于一体的巨跨被覆施工装备。该设备以贝雷架为支撑体系，底部设置行走机构，顶部设置混凝土浇筑平台和钢筋绑扎作业平台，采用液压、电气控制与驱动技术，多种自动化机构辅助施工，可实现一次定位，钢筋绑扎、混凝土浇筑多工序同步施工。应用结果表明，被覆施工一体化装备可有效降低人工劳动强度，提高施工效率，且施工质量良好，施工风险可控。

Abstract

A giant single-span underground cavern under construction faces technical issues of a large amount of rebar binding and concrete casting as well as high construction risks. Moreover, the simple platform is too complex and huge to move easily and work effectively. Based on the technical advantages of a fully-hydraulic steel form-lined trolley and modular high-performance Beret frame, a construction equipment integrating the functions of rebar binding and concrete casting is developed for the secondary lining construction of giant-span caverns. The equipment is supported by a Beret frame with a walking mechanism at the bottom, a concrete casting steel formwork, and a steel binding working platform at the top. Hydraulic and electrical control as well as driving technologies are used to assist the construction with various automatic mechanisms, which can achieve one-time positioning and simultaneous steel binding and concrete casting. The application results reveal that the integrated equipment can effectively reduce the artificial labor intensity, improve efficiency, ensure the construction quality, and control the construction risk.

Key words： giant-span underground cavern; integrated equipment for secondary lining construction; Beret frame support system; steel binding; concrete casting
