Luzhongbao 400×400×40 Composite Rectangular Chamber

Product Features: Lightweight & High Strength,Anti-Theft Design,Cost-Effective & Durable
With the increasing importance of intensive utilization of urban underground space today, traditional inspection chambers often face installation difficulties at node locations such as pipeline branches and meter installations due to their oversized dimensions. Particularly in working conditions with strictly limited space like sidewalks, equipment foundation pits, and utility tunnel access points, it is essential to ensure both the structural integrity and functionality of the node while simultaneously minimizing the structural size to the greatest extent. The Luzhongbao 400×400×40 Composite Rectangular Chamber is a high-precision product developed specifically for this requirement. Through optimized square structure design and reasonable wall thickness, this product achieves minimal spatial occupancy while ensuring functional utility, reflecting the technical trend of municipal engineering components towards standardization and modularization. This product utilizes a high-performance composite material system and a computer-aided engineering optimized structure. Its external dimensions are 400mm × 400mm × 40mm (wall thickness). This meticulously designed size provides sufficient operating area within a confined space. The standard 40mm wall thickness, combined with the integrally molded internal reinforcing structure, collectively ensures the product's mechanical performance. The product maintains the excellent characteristics of composite materials: corrosion resistance, electrical insulation, and no scrap value. Its smooth internal surface and standardized interface design ensure smooth pipeline connections. This rectangular chamber is particularly suitable for scenarios with strict spatial constraints, providing an optimized solution that combines practicality and economy for compact underground nodes.

Product Description Luzhongbao 400×400×40 Composite Rectangular Chamber: An Engineered Optimized Solution for Compact Spatial Underground Nodes. Material System and Manufacturing Process The performance advantages of this rectangular chamber stem from its scientific material formulation and advanced manufacturing process. The matrix uses high-strength unsaturated polyester resin, modified with anti-aging additives, significantly enhancing the material's durability. The reinforcement system employs a composite structure of chopped glass fibers and continuous fiber mat, ensuring isotropic properties while achieving directional reinforcement in key areas. The manufacturing process utilizes computer-controlled hydraulic presses matched with high-precision molds for compression molding. Precisely controlled process parameters ensure the resin flows sufficiently and completely impregnates the fibers, forming a dense and uniform composite structure. Special surface treatment technology applied to the molds gives the product smooth inner and outer surfaces, effectively reducing fluid resistance and the probability of fouling. Structural Design and Mechanical Performance The structural design of this product fully considers the balance between practicality and reliability. The standard 40mm wall thickness, working in conjunction with the scientifically distributed internal rib network, forms a stable load-bearing system. Addressing the mechanical characteristics of square structures, reinforcement design applied to the diagonal areas significantly improves the product's compressive capacity and deformation resistance. Professional testing verifies that the ring stiffness of this rectangular chamber reaches SN10 grade, and its load-bearing capacity meets the requirements for use in areas such as sidewalks and green belts. Standard interfaces set around the chamber body can adapt to pipeline connections of different diameters. The non-slip footstep design provides safe and convenient operating conditions for maintenance personnel. Engineering Applications and Comprehensive Value In practical engineering applications, this rectangular chamber demonstrates significant value. Its compact size minimizes the occupation of underground space to the greatest extent, making it particularly suitable for pipeline installation and maintenance in densely built-up areas. The lightweight characteristic of the product makes transportation and installation more convenient, greatly reducing construction difficulty and costs. From a whole-life-cycle cost analysis, the product's design service life exceeding 25 years and extremely low maintenance requirements give it a clear comprehensive cost advantage. The characteristic of having no scrap value completely solves the theft problem, while its excellent corrosion resistance ensures long-term reliable operation in complex environments. Summary The Luzhongbao 400×400×40 Composite Rectangular Chamber is a practical engineering component developed specifically for space-constrained scenarios, successfully achieving a unity of functionality and economy. Through reasonable material selection and structural design, the product provides a reliable solution for compact underground nodes, reflecting the direction of modern municipal engineering towards refinement and standardization. Choosing this product means providing an ideal technical choice for the construction of underground facilities under special working conditions.
