Amid the trend of urban underground space development moving towards greater depth and intensification, traditional inspection chambers face severe challenges under working conditions with over 3 meters of cover depth. Conventional composite circular wells are prone to structural deformation under deep soil pressure, while concrete inspection wells suffer from issues like difficult installation and high risk of foundation settlement due to excessive self-weight. The Luzhongbao 750×1000×100 Composite Circular Well, developed specifically for harsh conditions such as deep pipeline networks, underpass tunnels, and high fill areas based on deep soil pressure mechanics analysis and advanced composite material technology, is becoming a highly favored solution in the field of deep underground engineering.
This composite circular well adopts an optimized dimensional design of 750mm inner diameter × 1000mm outer diameter × 100mm wall thickness. This specification is the result of deep soil pressure simulation calculations and structural optimization analysis, achieving optimal structural stability while ensuring sufficient internal space. The 100mm ultra-thick wall layer, combined with the internal three-dimensional reinforcement rib network, forms an efficient spatial load-bearing system. The product uses a high-performance vinyl ester resin matrix reinforced with multi-axial warp-knitted fiberglass fabric, offering exceptional corrosion resistance, creep resistance, and structural strength. Its innovative spigot-and-socket segmented design meets different burial depth requirements, which is the key reason for its standout performance in deep underground engineering.
Exceptional Deep Load-Bearing Performance
The core advantage of the Luzhongbao Composite Circular Well lies in its outstanding adaptability to deep soil pressure. The well wall structure designed through topology optimization algorithms forms a scientifically distributed multi-directional reinforcement rib system within the 100mm wall thickness, enabling the well body to achieve a ring stiffness of SN25 or higher. It can be safely applied in extreme working conditions with over 5 meters of cover depth. This structural design effectively solves the technical challenge of deformation susceptibility in traditional products in deep environments.
Innovative Segmented Structural Design
This composite circular well adopts a modular segmented structure, with individual section heights of 1 meter, allowing flexible stacking via spigot-and-socket joints. The triple O-ring seal design and self-locking mechanism at the joint ensure connected sections form a continuous, uniformly stressed whole, effectively avoiding structural risks caused by weak joints, providing reliable assurance for deep engineering construction.
Excellent Durability Performance
The material combination of a vinyl ester resin matrix and multi-axial warp-knitted fiberglass fabric gives the product excellent chemical corrosion resistance, making it particularly suitable for corrosive environments like industrial parks and leachate collection systems. The product's design service life is not less than 50 years, requiring almost no maintenance throughout its entire lifecycle. This long-term reliability saves project owners significant maintenance costs.
Significant Construction Convenience
Engineering practice shows that the installation efficiency of this composite circular well is significantly improved compared to traditional products. Its segmented modular design makes transportation and hoisting extremely convenient. On-site assembly requires no large machinery, and installation speed is several times faster than traditional methods, greatly shortening the project timeline and reducing construction risks and impacts on the surrounding environment.
Comprehensive Economic Benefits
From a whole-life-cycle cost perspective, this composite circular well demonstrates significant economic advantages. Although the cost per section is higher than ordinary products, considering its maintenance-free reliability in deep burial environments, its ultra-long service life exceeding 50 years, and the substantial savings in maintenance costs, its long-term economy is unparalleled. Furthermore, its completely insulating and non-magnetic characteristics make it particularly suitable for precision engineering areas with strict electromagnetic interference restrictions.
Wide Application Adaptability
The innovative design of this composite circular well enables it to adapt to various deep underground engineering needs. Whether in deep pipeline networks, underpass tunnels, high fill areas, or regions with special geological conditions, it can provide reliable performance. This wide application adaptability makes it an ideal choice for deep underground infrastructure construction.
Perfect Combination of Environmental Protection and Safety
The product is manufactured using environmentally friendly materials, and the production process meets green construction requirements. Its exceptional structural safety performance effectively ensures the long-term stable operation of deep underground engineering. The innovative sealing system prevents groundwater pollution, fully reflecting the high importance modern engineering construction places on environmental protection and safety.
Summary
The reason why the Luzhongbao 750×1000×100 Composite Circular Well has become the preferred choice for deep underground engineering stems from its innovative structural design, exceptional load-bearing performance, convenient construction characteristics, and significant economy. This product successfully solves the technical bottlenecks of traditional inspection wells under deep working conditions, providing reliable technical support for the development of urban underground space towards greater depth. Choosing this product means selecting a quality commitment and safety guarantee spanning half a century for deep underground engineering, which is the fundamental reason for its widespread recognition in major engineering projects.
