Description

Technical Field

[0001] The present invention relates to the application field of electromechanical engineering construction technology, and in particular to a method for rapid assembly construction of super-high-rise pipe wells and pipelines based on BIM technology. Background Art

[0002] Prefabricated construction in my country's construction industry is in a stage of rapid development. Electromechanical assembly technology is gradually being applied to different projects in various forms due to its advantages of standardization, refinement, and pre-processing. At present, electromechanical assembly technology can be divided into two types, namely split assembly and integral assembly. Split assembly is divided into large split assembly and small split assembly with on-site splicing of components. The use of integral assembly is more demanding and is suitable for locations with small sites, moderate equipment, relatively regular and convenient transportation. Electromechanical installation projects are limited by the progress of the main construction, and have difficulties such as tight construction period, many cross-operations, large coordination, and few construction sites. Integrated assembled electromechanical will solve these problems well, especially for super high-rise buildings. Summary of the invention

[0003] The purpose of the present invention is to provide a method for the rapid assembly construction of super high-rise pipe wells based on BIM technology, using BIM related software to achieve parametric modeling and integrated construction of electromechanical pipelines, reduce the difficulty of electromechanical installation of super high-rise pipe wells, and improve the construction accuracy and efficiency of complex electromechanical pipelines. The construction method includes the following steps:

[0004] Step 1: Create the initial model of the main body of the project, electromechanical, etc. according to the design drawings, pipeline comprehensive layout rules and other modeling standards, integrate the completed models, and optimize and determine the pipeline comprehensive construction plan;

[0005] Step 2: According to the contents described in step 1, design the bracket, structural beam and slab reservation according to the deepened BIM pipe model, and generate the final material list including pipelines, bracket steel and other auxiliary materials;

[0006] Step 3: According to the contents described in step 2, the determined integrated electromechanical pipe well is subjected to stress analysis to determine the position and number of hanging points, and the integrated processing and production of civil engineering and electromechanical pipelines are carried out in the factory according to the final electromechanical pipeline plan;

[0007] Step 4: According to the contents described in step 3, after the construction site is ready for construction, the integrated electromechanical pipe well unit is transported to the range of the lifting equipment and hoisted to the designated construction location. After temporary fixation and accurate detailed positioning, it is formally fixed and poured with self-compacting concrete;

[0008] Step 5: After the construction of the pipe well electromechanical module unit is completed, it is connected to the horizontal main pipe and branch pipe on the same floor to close the water supply to achieve rapid construction;

[0009] Furthermore, in step 1, BIM software is used to construct and integrate subsystem models, perform collision detection on mechanical and electrical pipelines and structures, adjust the comprehensive layout model of mechanical and electrical pipelines in the pipe well, optimize the design model layout, and determine the precise positioning of each pipeline in the plane and space in the pipe well;

[0010] Furthermore, in step 2, the brackets are arranged according to the final pipe layout, and the arrangement should meet the relevant requirements of the specifications; the structural beams and slabs around the pipe well are optimized to form tongues and grooves to facilitate overlap with the prefabricated slabs of the integrated unit module, and are cast into a whole by reserving dowels; the electromechanical pipeline model is planned according to the material list at a height of 2 floors to facilitate cutting and integrated assembly, and the pipe fittings of each system in the pipe well are numbered and the final material list and plane details are exported to guide subsequent construction; finite element analysis software is used to perform force analysis on the connection position between the integrated unit and the main structure. During the modeling process, the steel plate loaded on the top surface is coupled to a pre-set reference point, and the vertical displacement (using displacement loading) can be directly applied to the reference point, and then the displacement of the loaded steel plate in the x, y, and z directions at the bottom of the model and the displacement of the reference point in the x and z directions are constrained respectively. The interface between new and old concrete is simulated by nonlinear three-dimensional spring elements. The normal spring element constitutive model perpendicular to the bonding surface adopts the normal stress-bond slip model. The transverse tangent spring element constitutive model of the bonding surface (perpendicular to the loading direction) takes a large number of the same order of magnitude as the elastic modulus of concrete. The spring element constitutive model of the longitudinal tangent spring element (along the loading direction) of the bonding surface is uniformly adopted (K1s, 0 <s≤Se;K2(S-Se)+te,Se<s≤Su;K3(S-Su)+tu,Su<s≤Sr;tr,S> Sr) and the elastic-brittle bond-slip relationship of the specimen are determined;

[0011] Furthermore, in step 3, a 3D solid model of the integrated hoisting unit is established by using 3D modeling software, and then the center of gravity of the hoisting unit is obtained by querying the software; the number and position of the hoisting points are determined by factors such as the lifting capacity of the hoisting equipment, the number of hoists, the influence of the setting of the hoisting points on the internal force and deformation of the structural members, and the stress characteristics of the structure itself, and the optimal number of hoisting points and the most reasonable hoisting point positions that should be used when the integrated hoisting unit is hoisted as a whole are analyzed, and the feasibility of the hoisting scheme is verified; the prefabrication and assembly of the integrated electromechanical pipe well is carried out in the factory, and the upper and lower structural floor slabs are first prefabricated by the tire frame through the model scheme, detailed drawings and blanking lists, and the reserved casing positions of the prefabricated panels are placed strictly according to the scheme, and concrete pouring can be carried out only after acceptance; after the concrete strength reaches the standard, the longitudinal filling wall is first built and plastered, and then the pipeline is installed, and finally the transverse walls on both sides are installed;

[0012] Furthermore, after the integrated electromechanical pipe well unit is hoisted to the designated position in step 4, the prefabricated structural plate of the integrated unit is aligned with the tongue and groove of the upper and lower structural beams, and the integrated unit is temporarily fixed to the surrounding main structure using materials such as channel steel, and then the verticality and flatness of the integrated unit are checked. It can only be formally fixed after the accuracy meets the requirements of the specification, and finally, after the prefabricated plate and the reserved dowels of the structural beam are tied and accepted, high-strength self-compacting concrete is poured around the pipe well structural plate;

[0013] Furthermore, the installation of pipelines such as horizontal main pipes and branch pipes in step 5 can achieve the water-tightening phenomenon of the floor, and can realize the interlacing of processes, so as to achieve rapid construction; the riser of the pipe well electromechanical pipeline module should be connected to the horizontal pipeline of the floor in a relatively spacious position to avoid affecting the net height of the floor, and also reduce the construction difficulty of the pipeline connection;

[0014] The beneficial effects of the present invention are:

[0015] The present invention realizes modular modeling, assembly construction and rapid construction of super-high-rise pipe shaft electromechanical pipelines by utilizing BIM parametric software. It is not only applicable to places with small sites and inconvenient installation to improve construction efficiency, but also can achieve the purpose of precise control of the entire process of design and construction, realize process interlacing, and greatly improve the construction efficiency of super-high-rise electromechanical pipelines.
