in the machine room according to the manufacturer’s product atlas, and the components of each size are exactly the same as the atlas.

When using BIM for deepening design, parameters can be preset through dynamo programming, and the water pump module model can be automatically generated to realize the automatic drawing of components and the automatic export of component QR code, which greatly saves human and material resources and construction period costs.

Intelligent construction intelligent construction includes component transportation, material yard optimization design, intelligent robot information interface, etc.

▲ dynamo parametric programming ▲ dynamo pump unit module programming in the construction of machine room, there are usually many difficulties in the deepening design of water pump module.

Deepening the design on the basis of digitalization can convert the original two-dimensional plane drawings into 3D models and mark the necessary information, so as to guide the project construction more intuitively.

The key construction technology of ddci precast machine room is a set of standardized process that can guide the construction from the deepening design of the machine room to the completion acceptance.

After the pipeline is hoisted, use a level ruler to inspect.

Ddci construction technology system is a set of construction industrialization process system, which takes BIM Technology as the carrier, deepens the design as the premise, and takes prefabrication and assembly as the means.

▲ the detailed design of the implementation process of the detailed design mainly includes the detailed design of the equipment layout, the maintenance channel, the piping system, the precast assembly unit, the support and hanger, the equipment foundation and the drainage ditch.

▲ the platform lightweight model guides the on-site construction pipeline assembly to position and install according to the segment and code of the pipeline in the early BIM model, and the pipeline segment, support and hanger, code and positioning point correspond.

After the levelness and verticality meet the requirements, assemble and connect the pipeline and supports and hangers to ensure that the actual situation of the machine room is consistent with the construction model..

Customized processing customized processing includes component information export and full professional prefabrication.

▲ during the assembly process of the three-dimensional scanning + automatic lofting robot, the three-dimensional scanner is used to scan the structure, form the point cloud data, correct the deviation between the structure and the model, import the corrected and adjusted BIM model into the 360 automatic lofting robot, select the positioning points on the operating plate, and accurately loft and locate, so that the pump unit modules and equipment, pipelines and supports and hangers can be accurately installed in place in the later stage.

Full professional prefabrication is based on various processing drawings such as pump unit module processing drawing, pipe section processing drawing, support and hanger processing drawing, and carries out blanking, assembly, welding and pressing on the mature processing and production line of the factory.

Magnetic Steel Chamfer

For long and heavy pipelines, lifting points shall be added in the middle.

Digitalization includes compiling the coding system and family library of precast machine rooms.

China Construction Eighth Engineering Bureau combines ddci construction technology system with machine room construction to form the key construction and construction technology of ddci precast machine room, so as to achieve the architectural industrialization of machine room construction.

Deepening design deepening design includes system optimization design and unit module design.

Component information export is to export the preset parameters of each module to excel through dynamo programming, and export the QR code with qrcdor module to realize the automatic drawing of components and the automatic export of component QR code.

Ddci construction technology system ddci construction technology system includes four features: digitalization, deepnengdesign, customization, and intelligentmanufacturing.

▲ the family library component standardization assembly type machine room supporting family library models the water pump, rubber flexible joint, filter, butterfly valve, check valve, etc.

The serial code interval is set for different component categories to ensure the modification and expansion of the parameter code.

This not only ensures that a large number of processing work is not limited by the site, but also greatly improves the processing quality.

When lifting the pipeline, both ends shall be lifted at the same time.

It is a means to refine, supplement and improve the drawings based on the preliminary design drawings and according to the actual situation, so as to realize the unity of drawings, so as to directly guide the on-site construction and ensure that the final effect is more beautiful and reasonable.

The parameter code is unified and can be used for all projects.

In order to ensure accuracy, the component code adopts the principle of one project one compilation, and each specific component of different projects has its own code; The parameter code has 6 digits in total, which is divided into four categories according to the parameter attribute.

After the modeling is completed, the family naming, parameter coding, parameter formula are standardized according to the coding system, ensuring the accuracy of digitization.

For example, the intersecting line plasma cutting machine is used to cut raw materials, and the automatic welding robot is used to weld, realizing millimeter level processing error.

This technology has been applied in many projects such as Qingdao youth football field of Qingdao International Conference Center, It reduces the construction cost, improves the construction quality and promotes the forming appearance.

Digitalization refers to the conversion of components and their parameters used in machine room assembly into coding form, so as to realize the smooth interaction of information between different systems.

At the stage of delivery and transportation after the completion of customized processing of components, each component is identified with RFID electronic tags to realize the transportation and distribution of Internet of things, track the transportation progress in real time, and make a reasonable plan for the stacking of precast components according to the assembly sequence of each precast pipe section in advance after the pipe section enters the site, so as to avoid random stacking, ensure the “pick up as you load” in the construction process, and realize the efficient transportation of materials.

The wide application of this technology has significantly improved the quality, progress and safety management in the construction of the machine room.

▲ the coding system manual of the precast machine room the coding system of the precast machine room stipulates the code of each component used in the machine room assembly, and also sets the code for the parameters of the component, which is distinguished according to the family type and component category.
