by Sao Nian, I see that you have exquisite bones and are one of the engineering talents in the world.
Building high-quality projects depends on you.
I have a book called ‘A Treasure Book for Developing Small Components’, which is destined for you.
I have given it to you for free! Thank you, master.
I didn’t expect simple and ordinary small components to be produced in such a standardized manner in the Zha (Malong) Daohe (Tanghe) Highway Project of the Second Company located in Qinghai.
Yes, the Knock Down Highway project is really skilled! Don’t talk too much, the first move of the treasure book, get up! Aerial View of Small Component Prefabrication Yard: The Small Component Prefabrication Yard (hereinafter referred to as the Small Component Yard) of the Zhadao Highway Project is located on the main roadbed of the interchange, between the K49+000~K49+150 section and the EK0+700~EK0+800 section of the E-turn road foundation of the Huangyuan South Interchange.
It is mainly responsible for the prefabrication of small concrete components such as slope protection hexagonal blocks, arch frameworks, and ditch covers within the construction scope of the project.
The small construction site covers an area of 4000 square meters, with a building area of 2800 square meters and a total prefabricated capacity of 10356 meters ³。 The planning of the small component prefabrication yard is reasonable, clean, and tidy.
The yard is divided into reinforcement processing area, prefabricated component production area, demolding area, spray curing area, and finished product storage area.
The construction and production standards are orderly, facilitating on-site production management and quality control.
At the same time, all areas within the site have been hardened, and vertical and horizontal drainage ditches have been set up inside the site.
The drainage ultimately collects into the sedimentation tank for secondary sedimentation and recycling.
The spacious outdoor parking area and finished product display area are clearly marked with seven signs and two diagrams.
The safety operation procedures are shown on the production line.
The process flow chart of concrete pouring into the mold is shown on the production line.
The high-pressure release agent coating equipment is used to apply the release agent, ensuring uniform application of the release agent.
The project adopts a new type of demolding agent, effectively ensuring that the surface of the prefabricated concrete components after demolding is smooth and free from honeycomb and pitted surfaces.
High pressure release agent coating and mold cleaning agent equipment, prefabricated block loading and unloading pliers, finished product spray curing, demoulding after the concrete reaches 70% strength, and transportation to the curing area for spray curing.
The spray maintenance system adopts time relay timing automatic control, and each spray pipeline is equipped with an electromagnetic valve to control the spray water volume, spray time, and spray range.
A spray nozzle shall be set every 3m of the spray pipe, and different angles shall be set to spray the atomized curing water evenly on the concrete surface of the component to ensure adequate curing.
Prefabricated block spray curing hollow hexagonal blocks are maintained using high-strength material shaping templates to ensure that the size of the prefabricated component mechanism fully meets the design and specification requirements.
The signs of Qinghai Jiaotou and Tiedao Road are added to the ditch cover plate
