Underground box body structure correction method based on BIM

Abstract

The invention discloses a BIM-based underground box body structure correction method. The method comprises the following steps: actually measuring deviation; carrying out BIM (Building Information Modeling); the deviation rectifying device is in place; deviation correction operation is started; the deviation correction operation is completed; and after confirmation, seam processing is started. According to the underground box body structure correction method based on the BIM, the corresponding deviation coordinate points are measured on site, the BIM model is established according to the deviation coordinate points, then the jack oil cylinders are installed on the two sides of the box body, and then deviation correction operation is started, so that the underground box body is free of disassembly during deviation, loss is reduced, and the construction period is shortened; according to the deviation correcting device for the underground box, the construction waste is reduced, deviation adjustment of the heavy underground box can be achieved, deviation correcting operation is easy, efficiency is high, meanwhile, safety is high, orderly adjustment of the deviated box can be achieved through complete deviation correcting operation, and finally the linear design requirement is met.

Description

technical field [0001] The invention relates to the technical field of underground box structure correction, in particular to a BIM-based underground box structure correction method. Background technique [0002] At present, the underground box and the long-strip segmental structure of the underground box have a large amount of construction work and are widely used. The box structure is constructed in sections, and flexible deformation joints are designed between each section. , During the construction process, due to external influences, such as unsymmetrical backfilling, heavy rain, etc., the backfill is easily disturbed. After this happens, the existing technology can only use the deviated box to be re-constructed at the original position. This method exists The following defects: [0003] 1. When the displacement of the underground box structure changes, it cannot meet the design line type requirements, and there is no corresponding equipment. The existing method is to ...

AI Technical Summary

Problems solved by technology

[0002] At present, the underground box and the long strip segmental structure of the underground box have a large amount of construction work and are widely used. The box structure is constructed in sections, and flexible deformation joints are designed between each section. The weight of a single box is far less than that of a large foundation for building construction. , due to external influences during the construction process, such as unsymmetrical backfilling, heavy rain, etc., it is easy to be disturbed. After this situation occurs, the existing technology can only use to break the deflected box and re-construct in the original position. This method exists The following defects:

[0003] 1. When the displacement of the underground box structure changes, it cannot meet the design line type requirements, and there is no corresponding equipment. The existing method is to dismantle and clean up and then re-construct. The loss is high and the cost is high. The delay in the construction period also caused a large amount of construction waste;

[0004] 2. When the existing underground box structure deviates, the position is irregular, generally inclined, and the deviation is one end large and the other end small, which belongs to asymmetrical adjustment and is difficult;

[0005] 3. If the deviation of the underground box structure is to be adjusted dynamically, the adjustment process needs to be dynamically adjusted according to the actual situation, which is difficult to achieve with existing control methods
