Description

Technical Field

[0001] This invention belongs to the field of information technology in building engineering, and in particular to a method for managing the progress and quality of multi-pile construction based on BIM technology. Background Technology

[0002] BIM (Building Information Modeling) is a new tool for architecture, engineering, and civil engineering. The term "Building Information Modeling" was coined by Autodesk. It describes computer-aided design methods that primarily use 3D graphics, are object-oriented, and relate to architecture. Its main function is to assist in the design, construction, operation, and maintenance of projects in the civil engineering field, serving as a tool for managing the entire lifecycle of a project. In recent years, BIM technology has been used in the engineering construction field, but its application in pile foundation construction remains insufficient in depth and breadth, failing to effectively improve the efficiency of multi-pile construction progress and quality management.

[0003] Pile foundations are the basic structural elements of a building, serving to distribute the building's load and allow the surface structure to withstand greater loads. The quality of the pile foundation directly impacts the overall quality of the construction project. With increasing engineering complexity, more and more projects require the use of various pile types to meet the building's requirements. Currently, construction plans and schedules for multiple pile types are prepared by the construction team based on design drawings and practical engineering experience. However, during actual construction, differences in construction techniques, speeds, and site layouts for different pile types, as well as the lack of preliminary geological exploration and the resulting suspension of pile foundation construction due to interlayers or isolated boulders, can all lead to deviations in the construction plan and severely impact the construction progress.

[0004] In the process of construction quality management, the construction party and the supervision party mainly record the entire process of pile foundation construction and compile paper archives. However, there are many links in pile foundation quality management, the relevant technical parameters are complex and cumbersome, and paper documents are easy to get messy and lost. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a multi-pile construction progress and quality management method based on BIM technology. By generating a three-dimensional geological model and site functional layout through BIM technology, the construction process of multiple pile types on site is simulated. The simulation construction of different pile types is carried out in a visualized and parametric form to achieve the purpose of optimizing the pile foundation progress and controlling the pile foundation quality.

[0006] The technical problem solved by this invention is achieved through the following technical solution:

[0007] A method for managing the construction progress and quality of multi-pile structures based on BIM technology includes the following steps:

[0008] Step 1: Organize and collect geological survey reports and geophysical exploration reports for the construction area, and extract relevant information from the geological survey reports and geophysical exploration reports;

[0009] Step 2: Perform the first data fusion processing on the relevant information from Step 1 to obtain the first three-dimensional geological model;

[0010] Step 3: Based on the overall layout of the construction area, perform static layout of the first three-dimensional geological model, and make dynamic adjustments and optimizations according to the construction situation;

[0011] Step 4: Organize and collect the pile point construction design drawings, and perform a second data fusion process between the pile point data information in the pile point construction design drawings and the three-dimensional geological model after static layout to generate a second three-dimensional geological model containing pile point data information.

[0012] Step 5: Establish a unified elevation and position system. Based on the pile point construction design drawings, determine the construction range of multiple pile types within the construction area, create different pile foundation models, merge the rock strata with the pile foundation models, and select different pile forming processes.

[0013] Step 6: Combine the various mechanical information of different pile types, the site layout requirements for pile forming process, and the second three-dimensional geological model for a third data fusion process to obtain the optimal construction route and dynamic site layout map for multiple pile types.

[0014] Step 7: Conduct a visual briefing on pile foundation construction using a pile foundation construction simulation animation, clarifying key points, difficulties, and complex construction areas, and analyzing various risk factors during the construction process;

[0015] Step 8: Based on the simulation animation of pile foundation construction, determine the construction quality management parameters for different pile forming processes; during the construction process, the construction manager conducts full-process pile foundation tracking and control acceptance, synchronously records detailed data of each process and each control point, takes photos and uploads them to form a pile foundation quality acceptance process sheet.

[0016] Furthermore, the relevant information in the geological survey report in step 1 includes: identifying the type, depth, distribution, and engineering characteristics of the soil and rock layers within the building area; analyzing and evaluating the stability, uniformity, and bearing capacity of the foundation; identifying buried river channels, tombs, air-raid shelters, and isolated boulders that are detrimental to the project; identifying the burial conditions of groundwater and providing information on the stable groundwater level and its variation range.

[0017] Furthermore, the relevant information in the geophysical exploration report in step 1 includes: the distribution of underground pipelines and underground structures, specifically including the planar location, elevation, burial depth, direction, nature, material, number and specifications of underground pipelines for water supply, drainage, electricity, telecommunications and gas within the design requirements. Drainage includes rainwater, sewage and combined sewer systems.

[0018] Moreover, the specific implementation method of step 2 is as follows: the relevant data information in the geological exploration report and the geophysical exploration report are processed by data fusion for the first time, and the three-dimensional characteristic geodetic coordinates of X, Y and Z obtained from the drilling data are used to simulate the distribution of soil layers and generate rock strata and rock layers to obtain the first three-dimensional geological model.

[0019] Moreover, the specific implementation method of step 3 is as follows: establish a three-dimensional static layout model of the site to simulate the overall layout of the construction area, arrange the location of the on-site steel reinforcement shed, construction passage, project office area and living area, set the storage location of various machinery and materials in the site, dynamically adjust the overall layout in real time according to the construction situation, and arrange construction machinery.

[0020] Furthermore, the pile types in step 5 include: cast-in-place concrete piles, precast concrete piles, and steel piles; the pile forming processes include: mud wall drilling, bored cast-in-place piles, casing wall drilling, bored cast-in-place piles, and static pressure precast piles; the pile forming process should be selected based on the construction equipment, construction environment, construction experience, and the supply conditions of pile materials, in accordance with the principles of safety, applicability, and economic rationality.

[0021] Furthermore, the site layout information required for the pile-forming process in step 6 includes: the mud pit and sedimentation tank required for the cast-in-place piles, the temporary layout area for the reinforcing cage and PHC piles, and the concrete truck pouring route.

[0022] Furthermore, the construction quality management parameters for different pile-forming processes in step 8 include: construction quality management parameters for cast-in-place piles and construction quality management parameters for precast piles.

[0023] Furthermore, the construction quality management parameters for cast-in-place piles include bearing capacity, hole depth, pile integrity, concrete strength, hole diameter, mud index, reinforcement cage quality, and concrete slump index.

[0024] Furthermore, the construction quality management parameters for precast piles include, but are not limited to, bearing capacity, pile integrity, finished pile quality, pile location, pile top elevation, and welding quality.

[0025] The advantages and positive effects of this invention are:

[0026] 1. This invention generates a first three-dimensional geological model of the construction area through geological survey reports and geophysical exploration reports. The pile point data information is then fused with the data from the first three-dimensional geological model to generate a second three-dimensional geological model. Finally, based on the pile forming process, various mechanical information of different pile types, and the site layout requirements required for the pile forming process, the data from the second three-dimensional geological model is fused to generate the final three-dimensional geological model. The final three-dimensional geological model simulates the site layout and the entire process of pile foundation construction, and is used to guide on-site construction, realizing the visualization and dynamic management of multi-pile type construction.

[0027] 2. This invention overcomes the differences in construction technology, construction speed, and site layout among different pile types, as well as the suspension of pile foundation construction due to interlayers or isolated boulders caused by the lack of engineering geological exploration in the early stages of construction. It generates a three-dimensional geological model and site functional layout using BIM technology, simulating the construction of different pile types in a visualized and parametric manner. This reveals the relationships between components that are difficult to analyze in two-dimensional drawings. The model can be viewed from multiple angles and from all directions, making it more intuitive and easier for workers to understand, thus improving the effectiveness of construction plan briefings. Simultaneously, it enables information-based management and control of pile foundation construction quality, linking the quality acceptance process with the pile foundation BIM model to achieve dynamic management and visualization of pile foundation quality acceptance, thereby optimizing pile foundation progress and controlling pile foundation quality.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] A method for managing the construction progress and quality of multi-pile construction based on BIM technology, such as Figure 1 As shown, it includes the following steps:

[0031] Step 1: Organize and collect geological survey reports and geophysical exploration reports for the construction area, and extract relevant information from the geological survey reports and geophysical exploration reports.

[0032] The geological survey report in this step mainly includes, but is not limited to: identifying the type, depth, distribution, and engineering characteristics of the soil and rock layers within the building area; analyzing and evaluating the stability, uniformity, and bearing capacity of the foundation; identifying buried objects that are detrimental to the project, such as river channels, tombs, air-raid shelters, and isolated boulders; identifying the burial conditions of groundwater and providing information on the stable groundwater level and its variation range.

[0033] The geophysical exploration report in this step mainly includes, but is not limited to, the distribution of underground pipelines and underground structures. Specifically, it refers to the information such as the plane location, elevation, burial depth, direction, nature, material, number, and specifications of underground pipelines such as water supply, drainage (including rainwater, sewage, and combined sewer), electricity, telecommunications, and gas within the design requirements.

[0034] Step 2: Perform the first data fusion processing on the relevant information from Step 1 to obtain the first three-dimensional geological model.

[0035] The specific implementation method for this step is as follows:

[0036] The relevant data from the geological exploration report and geophysical exploration report are fused together for the first time. Using the three-dimensional geodetic coordinates of X, Y, and Z obtained from the drilling data, the distribution of soil layers is simulated to generate rock strata and rock layers, thus obtaining the first three-dimensional geological model.

[0037] Step 3: Based on the overall layout of the construction area, perform static layout of the first three-dimensional geological model, and make dynamic adjustments and optimizations according to the construction situation.

[0038] The specific implementation method for this step is as follows:

[0039] A three-dimensional static site layout model was established to simulate the overall layout of the construction area. The construction site was divided into zones with clear boundaries, including a material processing area, a material storage area, construction access roads, an office area, and a living area. The parking locations of various machinery and the storage locations of materials were rationally planned to facilitate the entry and exit of machinery and the requisition of materials. Without violating safety regulations, the construction area was dynamically adjusted in real time to optimize the construction layout and maximize on-site construction efficiency.

[0040] Step 4: Organize and collect the pile point construction design drawings, and perform a second data fusion process with the pile point data information in the pile point construction design drawings and the first three-dimensional geological model after static layout to generate a second three-dimensional geological model containing pile point data information.

[0041] Step 5: Establish a unified elevation and position system. Based on the pile point construction design drawings, determine the construction range of multiple pile types within the construction area, create different pile foundation models, merge the rock strata and pile foundation models, and select different pile forming processes in accordance with the soil layer and soil quality requirements in the "JGJ 94-2008 Technical Specification for Building Pile Foundations" while taking into account the surrounding environment and environmental protection requirements.

[0042] The pile types used in this step include, but are not limited to, cast-in-place concrete piles, precast concrete piles, and steel piles. Pile-forming techniques include, but are not limited to, slurry wall drilling (excavation) of cast-in-place piles, casing wall drilling (excavation) of cast-in-place piles, and static pressure precast piles. Furthermore, the pile-forming technique should be selected based on the principles of safety, applicability, and economic rationality, taking into account factors such as construction equipment, construction environment, construction experience, and the availability of pile-making materials.

[0043] Step 6: Combine the various mechanical information of different pile types, the site layout requirements for pile forming process, and the second three-dimensional geological model for a third data fusion process to obtain the optimal construction route and dynamic site layout map for multiple pile types.

[0044] The site layout information required for the pile-forming process in this step includes, but is not limited to: mud pits and sedimentation tanks required for cast-in-place piles, temporary layout areas for reinforcing cages and PHC piles, and concrete truck pouring routes.

[0045] Step 7: Conduct a visual briefing on pile foundation construction using a pile foundation construction simulation animation. Explain in detail the key points, difficulties, and complex construction areas, and analyze various risk factors during the construction process. This will enable construction personnel, especially workers, to understand the locations of these risks and master preventive measures, thereby ensuring the personal and property safety of every construction worker.

[0046] Step 8: Based on the simulation animation of pile foundation construction, and in accordance with the requirements of "GB 50202-2018 Standard for Acceptance of Construction Quality of Building Foundation Engineering", determine the construction quality management parameters for different pile forming processes; during the construction process, the construction manager conducts full-process pile foundation tracking and control acceptance, synchronously records detailed data of each process and each control point, takes photos and uploads them to form a pile foundation quality acceptance process sheet.

[0047] This step encompasses the entire process, including but not limited to: pre-construction, during-construction, and post-construction. Construction quality management parameters for different pile-forming techniques include, but are not limited to: quality management parameters for cast-in-place piles and quality management parameters for precast piles. Specifically, the quality management parameters for cast-in-place piles include, but are not limited to, bearing capacity, hole depth, pile integrity, concrete strength, hole diameter, mud slurry parameters, reinforcement cage quality, and concrete slump; the quality management parameters for precast piles include, but are not limited to, bearing capacity, pile integrity, finished pile quality, pile location, pile top elevation, and welding quality.

[0048] This invention utilizes geological survey and geophysical exploration reports to generate a three-dimensional geological model of the construction area; establishes a three-dimensional site layout model for the project construction phase, and deploys the overall site construction; determines the types and categories of pile foundation construction based on design drawings, including but not limited to cast-in-place piles, PHC piles, and steel piles. It standardizes site elevations, creates pile foundation construction points, merges the three-dimensional geological model with the pile foundation points, considers the mutual influence factors in different pile foundation construction processes, simulates different pile foundation construction plans and routes, and rationally designs the optimal construction scheme and construction paths for various pile types; through three-dimensional visualization construction simulation, it derives relevant technical parameters of the pile foundation during the construction process to guide actual on-site construction.

[0049] This invention is used to guide construction parties to rationally plan the construction schedule of multiple pile types on site, accurately arrange construction plans, and accelerate the construction speed of pile foundation while ensuring construction quality.

[0050] It should be emphasized that the embodiments described in this invention are illustrative rather than limiting. Therefore, this invention includes, but is not limited to, the embodiments described in the specific implementation. Any other implementations derived by those skilled in the art based on the technical solutions of this invention are also within the scope of protection of this invention.
