Recently, the shotcrete supplied by China Construction Commercial Concrete Ganzhou Plant affiliated to China Construction Western Construction has been successfully applied in the EPC general contracting project of improving the quality and efficiency of sewage treatment facilities in the central urban area of Ganzhou City.
Shotcrete is the key material for foundation pit reinforcement, which can be closely attached to the wall of foundation pit and quickly form a high-strength rigid supporting layer. The material has excellent soil pressure resistance and impermeability, and has the function of collapse prevention. Because the construction does not need to erect the template, it is especially suitable for the foundation pit engineering with complex shape. The working principle of shotcrete is similar to the "liquid band-aid" in life.
Due to the strict requirements of shotcrete on gravel particle size, the technical team of Ganzhou Plant carried out special material research one month in advance to screen suitable aggregates; Focusing on the core requirements of foundation pit slope protection for concrete early strength and spray workability, the optimal mix proportion was finally determined by adjusting the key parameters such as cementitious material dosage and sand ratio.
As the project is located at the riverside, the excavation of foundation pit is facing the risk of slope instability. In the pouring process, the production and technical teams of Ganzhou Plant cooperate closely with the project construction party to guide the spraying operation parameters in real time on site, so as to ensure the uniform thickness and firm adhesion of concrete spraying. It greatly exerts the excellent filling and close ability of shotcrete and the characteristics of rapid condensation and early strength, and carries out closed support for the excavated slope, which effectively improves the stability of the foundation pit slope.
The successful application of shotcrete has been highly recognized by customers. Ganzhou Plant will continue to complete the follow-up supply with high standards of service and quality, and continue to enhance the brand influence of high-quality concrete in the field of infrastructure in Ganzhou.
It is reported that the project of improving the quality and efficiency of sewage treatment facilities in the central
urban area
of Ganzhou City is a key livelihood project in Ganzhou City. It involves the expansion of reclaimed water treatment plants, buried sewage treatment plants, sludge disposal plants and the renovation of 19 pumping stations, with a total length of over 50 kilometers.
