The application frequency of concrete precast components in highway projects is very high

In highway projects, precast concrete components are used very frequently, so what preparations are needed before use? Let’s listen to the introduction of the precast concrete component factory.

Detailed introduction of precast concrete component factory.

(1) Preparation of precast site.

When prefabricating bridge beams and slabs, the prefabrication site should be determined and selected based on the scale of the project, the demand for prefabricated parts, the prefabricated quantity, and the construction conditions. The layout planning of the prefabricated site should be based on minimizing the construction land and reducing on-site construction costs; the prefabricated site should be closed and managed, and various construction signs and warnings should be set up; combined with the size of the site and production needs, scientific zoning planning should be carried out for the precast site, such as the concrete mixing area, prefabricated production area, health care area, and storage area.

(2) Template customization.

The precast concrete component factory stated that the formwork of the bridge's prefabricated components should be adjustable in the mid-span section, so that it can adapt to changes in beam length; the flange, especially the flange of the T-beam, should have a rotatable bottom plate, which can effectively meet the changing needs of ultra-high cross slopes of bridges in mountainous areas. The formwork should be made of high-strength shaped steel formwork. In other prefabricated parts projects, high-strength thick plastic molds can also be selected depending on the actual situation.

(3) Preparation of raw materials.

Cement should be made of ordinary Portland cement that meets the quality standards, and its strength should be higher than the needs of bridge beam and plate projects; the mud content of sand and coarse aggregate must be controlled; tap water or clean river water should be used for prefabrication water. Sand and coarse aggregate should be stored separately during storage.The above is the entire introduction to the precast concrete component factory. I hope this introduction can be helpful to everyone. The company adheres to the business philosophy of "technology as the guide, talent as the foundation, and quality as the pillar" and pursues the principles of scientific management, continuous improvement, environmentally friendly construction, strict prevention, and safety assurance. Actively explore operating mechanisms and management models that meet the requirements of enterprise development, and be pioneering, pragmatic and innovative. Strive to achieve first-class management, first-class technology, and provide customers with high-quality services.

Cement drainage pipes are also called cement pressure pipes and reinforced concrete drainage pipes. The hydrated cement and steel bars solidify together to form a hard tube. The moist soil can continue the hardening process of the pipe body. As time goes by, the strength and hardness of the pipe body will gradually increase. Therefore, it is safer and more durable to bury it underground. The pipe body can withstand changes in underground pressure and can withstand the erosion of underground sewage or stray current, so the pipe body is strong and durable. The body of the cement pipe also has good heat resistance, flame retardancy and fireproofing are also its outstanding functions; non-metal is the material of the pipe body, so it is not magnetic. Single-core cables are placed in the pipe, and eddy currents will not be generated during power transmission. This double highlights the benefits of cement pipes. Cement pipes are mainly used for underground cable protection pipes, underground optical cable protection pipes, chimney pipes, irrigation pipes, and can also be used for the discharge of groundwater, oil or corrosive liquids and gases.
