Embodiment 1

[0053] A large bridge of a railway project in Shanxi adopts 60+100+60m continuous beams to cross the main channel of the river channel, and is constructed by hanging basket cantilever pouring method. Among them, No. 19 pier is located on the main line and is a (60+100+60)m continuous beam braking pier across the river. The foundation adopts a well-dug foundation with a thickness of 7.5m. 61.5m high. The continuous beam has a large span and uses a well-dug foundation, which has high requirements for line shape control and construction unbalanced weight. And the small mileage of No. 19 pier is close to the riverside, the foundation top is 8.2m higher than the design water level, the large mileage is a high and steep slope, the slope top is more than 40m higher than the foundation top, and the hillside is nearly 45 degrees steep.

[0054] The construction site is narrow and the construction environment is complex. Based on BIM-GIS technology, the virtual construction site of th...

Abstract

The invention discloses a construction method of a bridge high and steep slope pier virtual construction site. The method comprises the following steps that the modeling range and modeling content ofthe surrounding environment of a bridge site of a high and steep slope are determined; Determining the modeling content and the modeling principle of the high and steep slope bridge section; Determining modeling content of the construction equipment facility; Determining a bridge pier construction simulation process of the high and steep slope; Constructing a basic environment model by adopting anorthoimage with geographic coding and a digital elevation model; Refining the details of the steep slope by adopting a three-dimensional live-action model obtained by oblique photography of the unmanned aerial vehicle; BIM-for establishing high and steep slope bridge sections and construction facilities A GIS model; Determining the content of bridge pier construction organization comparison and selection of the high and steep slope; BIM for establishing unified coordinates-GIS data platform; Establishing the BIM- GIS model integration to BIM-GIS data platform. According to the method, the spatial relationship problem with the surrounding environment in the construction process is solved, the construction organization scheme is optimized, and a data foundation is laid for high and steep slope bridge pier construction management informatization based on a real three-dimensional scene.

Description

technical field [0001] The invention belongs to the field of civil engineering technology and bridge building construction simulation, and in particular relates to a method for constructing a virtual construction site of bridge piers with high and steep slopes. Background technique [0002] A railway bridge is a structure built for railways to cross rivers, valleys or other obstacles, and to realize the three-dimensional intersection of railway lines and railway lines or highways. With the enrichment and improvement of the railway network, the setting of bridge piers on high and steep slopes in mountainous areas frequently occurs. High and steep slopes are not conducive to the construction of bridge piers. When the high and steep slopes and high piers are superimposed together, it becomes a high-risk construction section, which has extremely high requirements for construction organization. [0003] Building Information Modeling (BIM) technology is a digital and informationa...
