Liaocheng Dinghe Trading Co., Ltd. specializes in the production and manufacturing of grouting anchor pipe, tunnel support grouting pipe, anchor grouting pipe, embedded grouting pipe, subway grouting pipe, disposable grouting pipe, high-pressure grouting pipe, and reusable grouting pipe. Welcome customers to purchase! The pipe shed and steel flower pipe for tunnel and bridge engineering are mainly used in tunnel projects with soft and broken surrounding rock that have strict restrictions on surrounding rock deformation and ground subsidence, such as soft and sandy strata, soft rock, rock piles, and fractured zones. Generally, they are arranged circumferentially along a part or all of the underground engineering section at a certain spacing to form a steel pipe shed support. The pipe shed pre-supporting is a temporary support method provided in advance to enhance the bearing capacity of the strata under special conditions to ensure safe excavation.

Liaocheng Dinghe Trading Co., Ltd. Metal Products Main Functions and Advantages:

Lianggong Effect: The pipeline arching construction supports the front and rear surrounding rocks as the fulcrum, forming a beam-like structure, which together create a shell-like structure surrounding the tunnel contour. This effectively inhibits the loosening and collapse of the surrounding rocks. Reinforcement Effect: The grouting slurry is injected into the fractures of the surrounding rocks through the pipeline wall, bonding and solidifying the loose rock mass, thereby improving the physical and mechanical properties of the soft (fragmented) surrounding rocks, enhancing their self-supporting capacity, and achieving the goal of reinforcing the surrounding rocks around the pipeline. Ring Groove Effect: The explosion shock waves and expanding explosive gases generated by the face blasting are reflected, absorbed, or deflected after encountering the dense ring-shaped grooves of the pipeline arching, significantly reducing the degree of damage and the range of disturbance caused by the reverse tensile waves. Ensuring Construction Safety: The pipeline arching support has a high stiffness, and in the event of a collapse during construction, the collapsed debris falls on the upper rock debris of the pipeline, providing cushioning. Even if the pipeline arching loses stability, its destruction is relatively slow.

Our company has always adhered to the corporate philosophy of "customer first, quality paramount,诚信 service, and continuous innovation." In the next five years, we aim to build a modern enterprise integrating science, industry, and trade through technology. We sincerely welcome all scientific research and development units, as well as engineering construction units, to join us in making greater contributions to the national construction cause.
