Luzhongbao 500×300×50 Composite Rectangular Chamber

Product Features: Lightweight & Sturdy,Inherently Anti-Theft,Corrosion & Rust Resistant
With the increasing complexity of urban underground pipeline networks today, traditional standard-sized inspection chambers often face challenges of insufficient adaptability in specific working conditions. Particularly along road curbs, pipeline transition sections, and space-constrained areas, it is necessary to ensure the basic functions of the inspection chamber while also meeting special spatial form requirements. The Luzhongbao 500×300×50 Composite Rectangular Chamber is an innovative product developed precisely to address this specialized need. This product adopts a unique rectangular design; the size ratio of the 500mm long side to the 300mm short side is precisely calculated to perfectly fit the installation requirements of narrow, elongated spaces, optimizing space utilization efficiency to the greatest extent while ensuring structural stability. This product is based on a high-performance composite material system and formed in one step using an advanced compression molding process. The optimized 50mm wall thickness and the scientifically arranged internal reinforcement structure ensure the product's mechanical performance under non-standard dimensions. The chamber interior is smooth and flat, effectively reducing fluid resistance; the four corners employ a rounded transition design to avoid stress concentration phenomena. This rectangular chamber inherits the excellent characteristics of composite products, offering advantages such as corrosion resistance, good insulation, and no scrap value, with a design service life of not less than 30 years. Its unique dimensional design is particularly suitable for layout along linear projects, providing a professional solution for underground pipeline network construction under special spatial conditions.

Product Description Luzhongbao 500×300×50 Composite Rectangular Chamber: A Professional Solution for Underground Pipeline Networks in Narrow, Elongated Spaces. Material System and Manufacturing Process The performance advantages of this rectangular chamber originate from its rigorous material formulation and manufacturing process. The matrix material selects high-performance unsaturated polyester resin. By adding anti-aging agents and UV stabilizers, the product's durability is significantly enhanced. The reinforcement material uses directionally distributed glass fibers, with focused reinforcement along the long side direction, effectively compensating for potential mechanical performance differences arising from the asymmetric structure. The manufacturing process employs a computer-controlled hydraulic molding system. Through precise control of temperature, pressure, and time parameters, it ensures the material is fully cured and the internal structure is dense and uniform. The mold design fully considers the deformation risks associated with the aspect ratio difference, incorporating special compensation mechanisms to guarantee product dimensional accuracy and shape stability. Structural Design and Mechanical Performance The structural design of this product focuses on resolving the stiffness issue along the long side direction of the rectangle. Through Finite Element Analysis, longitudinal reinforcing ribs are set on the inner side of the long edge, supplemented by transverse supports on the short sides, forming a stable spatial load-bearing system. The standard 50mm wall thickness, after optimization, ensures sufficient structural strength while avoiding material waste. Laboratory tests confirm that the ring stiffness of this rectangular chamber reaches SN12.5 grade, with particularly outstanding bending strength along the long side direction, fully meeting the load-bearing requirements for urban road auxiliary facilities. The pre-set interface positions on the chamber walls are carefully planned to adapt to the connection needs of pipelines with different orientations. Engineering Applications and Comprehensive Value In practical engineering applications, this rectangular chamber demonstrates unique value. Its narrow, elongated shape is particularly suitable for layout along linear spaces such as road edges and green belt boundaries, effectively reducing the impact on the main road structure. The product is lightweight with precise dimensions, greatly simplifying the construction process and improving installation efficiency. From a whole-life-cycle cost analysis, the product's long service life and low maintenance requirements give it significant economy. The characteristic of having no scrap value fundamentally prevents theft, while its excellent corrosion resistance ensures long-term reliable operation in humid environments. Summary The Luzhongbao 500×300×50 Composite Rectangular Chamber is a specialized product designed for special spatial requirements, successfully solving installation challenges in narrow, elongated working conditions. Through scientific dimensional design and structural optimization, the product achieves the optimal balance between function and performance within limited space, providing a new choice for modern urban underground pipeline network construction. This product reflects the trend of municipal facilities towards specialization and refinement, serving as an effective guarantee for improving engineering construction quality.
