BIM (building information modeling) combined utility tunnel intersection prefabricated component optimization method

Abstract

The invention relates to a BIM (building information modeling) combined utility tunnel intersection prefabricated component optimization method. The method includes steps: (1) adopting a BIM technique for modeling of a tunnel body and each functional node; (2) implementing dynamic monitoring on pipelines entering a tunnel according to modeling information, calculating structural dimensions required by communication of upper and lower chamber pipelines of main and branch utility tunnel intersections on the basis of information of the pipelines entering the tunnel, and analyzing and demonstrating calculated dimension information; (3) analyzing and demonstrating the calculated dimension information, and performing special secondary design of medium plate prefabricated components on the basis of the demonstrated dimension information; (4) prefabricating, namely manufacturing utility tunnel intersection prefabricated components according to secondary design results, and designing an integral utility tunnel intersection layout. The method has advantages of flexibility in mounting timeliness, convenience and quickness in component demounting and replacement and high integrating degree in long-term pipeline planning and capacity increasing.

Description

technical field [0001] The invention relates to the field of urban comprehensive pipe gallery engineering, in particular to a prefabricated component of the middle plate at the intersection of the main and branch line comprehensive pipe gallery (multi-chamber) with a high degree of long-term pipeline planning fit and convenient component replacement. Background technique [0002] The comprehensive pipeline corridor is a century-old project. The time limit for the planning of various urban pipelines is mostly consistent with the master plan. Generally, it is 20 years. Whether the prediction of the type and scale of future pipeline demand is accurate or not is related to whether the century-old project is scientific and reasonable, and there is no need to dig another road Direct burial or another channel. The advancement of science and technology and the improvement of people's quality of life have added uncertainty to the forecast of pipeline demand. [0003] Existing struct...

AI Technical Summary

Problems solved by technology

[0004] The existing structural design forms have the following shortcomings and deficiencies: ①The reserved size of the opening (due to the "forming" of the overall one-time pouring construction of the middle plate) has high requirements for the assessment of pipeline units

When the pipeline is installed in the "up and down crossing, Unicom" hole area, the working space is cramped and there are many installation obstacles

③When the pipelines entering the gallery need to increase the number of "crossing up and down, and connecting" at the intersection of the main and branch comprehensive pipeline corridors, if the reserved size of the overall design in the early stage is not enough, it cannot be realized
