Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1
The construction process planning and managing method based on the BIM is shown in the figure 1 and comprises the following processes:
step 1, establishing an engineering construction BIM three-dimensional model according to design files and design requirements of engineering projects, establishing a construction process flow model according to a construction process and a construction method, and enabling the established three-dimensional model to correspond to the construction process flow model according to the requirements of the construction process and the construction method; and then establishing a virtual construction resource model, wherein the virtual construction resource model comprises construction resources such as construction equipment, constructors and templates, and the templates refer to materials used in template engineering in engineering construction, such as wood templates and steel structure templates.
The BIM three-dimensional model of engineering construction can be established by utilizing Dasuo 3DE software based on the existing modeling module.
The 3DE software is used for establishing a construction process flow model, wherein the construction process flow model refers to a construction sequence to be followed when engineering is carried out, for example, a tunnel is excavated, blasting stone slag is firstly blasted, then rock slag is cleaned, and then supporting is carried out, and different engineering has different processes. The construction process flow model is composed of a plurality of single processes which are arranged according to a certain sequence.
After the engineering construction BIM three-dimensional model and the construction process flow model are established, if the two models are verified to be not corresponding, the established three-dimensional model can be returned to be modified until the two models are corresponding to each other.
And 3DE software is used for establishing a construction resource model, wherein the model belongs to an accessory attribute class and a virtual model for adding in a construction process and is designed for counting the occurrence frequency.
And 2, performing related distribution on the three-dimensional model of the engineering component, construction equipment used in the construction process, involved constructors and used construction resources completed in each process by taking the established construction process flow model as a bottom layer architecture foundation, and designating the working duration time for each process, and performing related distribution on each construction process in the construction process flow model in sequence.
A complete engineering construction BIM three-dimensional model is all structures of the whole engineering, all the structures are divided according to the working procedures to obtain a plurality of corresponding engineering component three-dimensional models, namely, the divided three-dimensional model units of the single engineering component can be completed in one working procedure.
Construction resources such as construction equipment and constructors can be repeatedly allocated, but the resources are not occupied any more after the previous procedure is finished. If two processes are carried out simultaneously and the same resource is used, a conflict is formed, the continuous working time of the processes is referred during the association and distribution, the conflict condition is avoided, or a mode of increasing the resource is adopted, and the process is ensured to obtain necessary construction resources.
And 3, obtaining the service conditions of construction equipment and construction resources, the working hours of constructors and the duration of the engineering required by the whole engineering after the association distribution is completed. The using condition of the construction resources is exported, the attendance rates of construction equipment and constructors can be counted, the utilization rate of the construction resources is evaluated, unreasonable resource allocation is found before construction, associated allocation can be modified, and the using condition of the resources is balanced.
Unreasonable case 1: the two processes are carried out simultaneously, the same resource is used, for example, two pits are arranged to be dug simultaneously, only one excavator is arranged, and conflict is formed;
unreasonable case 2: one operator is needed for a plurality of continuous processes, and the operator cannot continuously participate in construction;
unreasonable case 3: the engineering template is used in the previous process, and the next process is arranged to be used, so that conflict occurs.
The utilization rate of the construction resources is analyzed to be the work condition of the construction resources in use, for example, 2 digging machines are arranged on a construction site, one digging machine works for 12 hours every day, and the other digging machine works for 2 hours, which is unreasonable.
When the construction resources are distributed to the construction process, unreasonable arrangement is carried out, the resources are redistributed, for example, the working time of the two digging machines is balanced, the attendance time of constructors is adjusted, and the modified resource utilization conditions are analyzed again and modified until the construction progress and the cost are reasonably ensured to be optimal.
And 4, finally, carrying out construction simulation by using BIM software, checking whether a process flow error exists, and checking whether spatial interference occurs in the construction process so as to verify whether the construction scheme is reasonable. And after the construction scheme is verified to be reasonable, generating a construction task plan and a construction progress Gantt chart according to the construction process flow, and issuing the construction task plan and the construction progress Gantt chart to a construction unit for construction deployment.
The simulation means that the engineering construction BIM three-dimensional model automatically grows according to the planned construction process flow, whether the appearance sequence of the three-dimensional model accords with the reality, such as the construction sequence of a building, 7, 8 and 9 stories, and the sequence of 7, 9 and 8 can not appear is detected, whether the construction process flow is wrong or not is mainly detected, and the construction resource model is not analyzed.
Spatial interference means that the two components coincide in spatial position.
And 5, when the construction scheme is implemented on a construction site for construction, obtaining a virtual progress and an actual progress on a construction management system, referring to fig. 2, wherein the virtual progress is automatically loaded and executed by the system, the actual progress feeds back data to the system for loading according to the construction site, the two progresses are simultaneously displayed in the system, when the two progresses have non-negligible deviation (for example, project delay influences project delivery), a solution is provided for checking the problem according to the actual condition, the duration of a construction process in a construction process flow can be adjusted, or the construction process is redistributed on resource allocation, newly added resources and the like, and a new and reasonable construction task plan and construction progress are regenerated.
The BIM-based construction process planning management method comprises the steps of establishing a three-dimensional model of an engineering project, a construction process flow model and a virtual construction resource model, taking the construction process flow model as a bottom layer foundation, carrying out associated distribution on the three-dimensional model and the construction resources corresponding to the process, assigning work duration for the construction process, reasonably planning the construction process before construction, reasonably distributing the resources, forming a construction task plan and a construction progress guide, improving project management level and realizing efficient construction of the engineering project.
