Construction method for main trestle in deepwater area
The invention belongs to the technical field of main trestle construction, and discloses a construction method for a main trestle in a deepwater area. The method comprises the following steps of transportation of steel pipe piles: transporting processed steel pipes to a piling point by adopting a truck-mounted crane; steel pipe pile construction: interface cleaning; welding; cleaning and treatment of welding seams; transverse connection and steel corbel construction: transverse connection between the piles and construction of a steel corbel; construction of a lower cross beam: specifically, a pile top cross beam is I40b double-spliced I-shaped steel, and the pile top cross beam is integrally hoisted and placed after steel pipe pile construction is completed; construction of an upper structure: installing Bailey beams mounting of an upper cross beam and a bridge deck slab; construction of a safety protection handrail; and construction of a temporary power facility platform and a cable bracket. The main trestle construction method provided by the invention can be suitable for construction and erection of the main trestle in the deepwater area, the construction safety is high, and the construction period is short; the safety protection handrails are installed on the two sides of the main trestle, and the safety performance in the construction process is improved; and meanwhile, the purposes of rapid construction and guarantee of quality and construction period can be achieved, and better use prospects can be brought.
本发明属于主栈桥施工技术领域，公开了一种用于深水地区主栈桥施工方法，包括：钢管桩的运输：采用随车吊将加工好的钢管运送至打桩点；钢管桩施工：接口清理；焊接；焊缝清理及处理；横向连接及钢牛腿施工：桩间横向连接；钢牛腿；下横梁施工：桩顶横梁为I40b双拼工字钢，在钢管桩施工完成后整体吊放；上部结构施工：贝雷梁安装；上横梁及桥面板安装；安全防护栏杆施工；临电设施平台及电缆托架。本发明提供的主栈桥施工方法可适用于深水地区主栈桥的施工架设，施工安全性高、施工周期短；在主栈桥两侧安装安全防护栏杆，提高了施工过程中的安全性能；同时，还能够达到快速施工、保证质量及工期的目的，能够带来更好的使用前景。
