Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent management of construction sites, and in particular relates to a real-time display method of construction progress applicable to open excavation construction of foundation pits. Background Art

[0002] Currently, there are two ways to visualize the construction site: one is to establish a BIM model for model display, and the other is to use drones to shoot videos from high altitude. However, there are the following problems:

[0003] 1) Not real-time enough. The BIM model requires manual modification of the model to display the working conditions and progress, which will cause a certain amount of time delay. The drone project progress display requires a second flight and a lot of post-processing of the video data, which also takes 1-2 days of work. It cannot meet the needs of real-time on-site control.

[0004] 2) High labor consumption. The construction schedule requires the arrangement of special personnel to handle project models or conduct drone flights every day, which has high labor costs and heavy workload.

[0005] Therefore, how to provide a real-time display method for construction progress suitable for open excavation construction is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The present invention provides a real-time display method for construction progress applicable to open excavation construction of foundation pits, which automatically collects on-site construction conditions and automatically corrects excavation models without manual intervention, accurately reflecting on-site excavation conditions.

[0007] In order to solve the above technical problems, the present invention includes the following technical solutions:

Model zoning, dividing the entire excavation area soil into multiple cube blocks, rectangular blocks or prisms; 5. Color block design, setting each block to three states: unexcavated, excavated, and excavated, distinguished by three different color block colors;

[0010] Step S2, obtaining positioning information: 1. Building a positioning platform, building a GNSS Beidou positioning platform, importing a foundation pit model, and determining the model position based on the coordinates; 2. Equipment installation, installing Beidou positioning equipment on the cab and the lower swing arm of the excavator, and building a positioning platform in the background to obtain the three-dimensional spatial coordinates of the excavator body and the excavation point in real time. The positioning label of the cab is marked as A, and the label on the swing arm is marked as B; 3. Receiving positioning information, obtaining the spatial coordinates of the excavator based on the positioning platform;

[0011] Step S3, three-dimensional display of construction progress: 1. Display of excavator positioning information, based on displaying the excavator in label mode on the foundation pit model, the label position is the three-dimensional space coordinate position of the excavator positioning device A; 2. Real-time display of construction progress.

[0012] Furthermore, the ratio of the foundation pit model in step S1 to the actual project is 1:1.

[0013] Furthermore, in step S1, a GNSS Beidou measurement device is used to measure the spatial three-dimensional coordinates of each corner of the actual foundation pit to achieve three-dimensional spatial positioning of the foundation pit excavation surface.

[0014] Furthermore, in step S1, the central part of the foundation pit is divided into cubic blocks with a side length of 2 to 3 meters, and the edges of the foundation pit are divided into rectangular blocks or prismatic blocks.

[0015] Furthermore, in step S3, the design algorithm used for the construction progress display includes:

[0016] 1. All blocks are initially unexcavated;

[0017] 2. When positioning tag B is located in a certain block, this block is automatically set to positive excavation;

[0018] 3. When the positioning tag A is located in a certain block, this block is automatically set to be excavated;

[0019] 4. Once a block is automatically set to excavation, it cannot be adjusted back to non-excavation unless manually modified;

[0020] 5. When a block is automatically set to excavated, no automatic status modification is allowed except for manual modification;

[0021] 6. When a block is in active excavation for more than two weeks, the platform will remind the management personnel whether there is a machine failure;

[0022] 7. When the surrounding blocks have been in the excavation stage for more than two weeks, if this block is still in the unexcavated stage, remind the management personnel to come to the site for inspection.
