With the rapid development of urban underground pipeline network systems today, inspection wells, as critical nodes connecting various pipelines and facilitating operation, maintenance, and inspection, directly impact the overall reliability and service life of municipal engineering. Traditional concrete inspection wells have exposed problems during long-term use, such as foundation settlement due to excessive self-weight and structural aging caused by insufficient corrosion resistance. Ordinary composite inspection wells often struggle to meet the load-bearing requirements of main roads due to inadequate structural strength. The Luzhongbao 700×770×70 Composite Circular Well, based on advanced materials science and structural engineering technology, successfully solves these technical challenges through optimized wall thickness design and innovative structural reinforcement, and is increasingly becoming the mainstream choice in the field of municipal engineering.

This composite circular well adopts a precise structural design of 700mm inner diameter × 770mm outer diameter × 70mm wall thickness. This specification is optimized through rigorous mechanical calculations and Finite Element Analysis, achieving the optimal balance between structural strength and material usage while ensuring sufficient internal operating space. The 70mm thickened wall layer, combined with the internally three-dimensionally distributed reinforcement rib network, forms an efficient spatial load-bearing system. The product is manufactured using high-performance composite materials, offering exceptional corrosion resistance, impact resistance, and structural stability. Its precise spigot-and-socket joint design ensures installation convenience and sealing reliability, which is the key reason for its widespread popularity in various municipal engineering projects.
Excellent Structural Performance
The core advantage of the Luzhongbao Composite Circular Well lies in its outstanding structural load-bearing capacity. Through the 70mm thickened wall layer and the scientifically distributed reinforcement rib system, the well body achieves a ring stiffness of SN15 or higher, capable of withstanding dynamic loads generated by repeated heavy vehicle traffic. The unique structural design enables loads to be evenly transferred along the well wall, effectively avoiding stress concentration phenomena and ensuring structural integrity is maintained during long-term use.
Superior Durability Assurance
The circular well manufactured from high-performance composite materials possesses excellent chemical corrosion resistance, effectively resisting long-term erosion from acids, alkalis, microorganisms, and wastewater in the soil. The product has a design service life exceeding 30 years and requires almost no maintenance throughout its entire lifecycle. This long-term reliability saves municipal departments significant maintenance costs and management resources.
Innovative Construction Convenience
Engineering practice shows that the installation efficiency of this composite circular well is significantly improved compared to traditional products. Its precise spigot-and-socket joint design makes the installation process simple and fast. The modular structural characteristics make transportation and on-site assembly more convenient. The unique sealing system ensures the reliability of well body connections, greatly shortening the construction period and reducing overall project costs.

Significant Economic Benefits
From a whole-life-cycle cost perspective, this composite circular well demonstrates significant economy. Although the initial investment may be slightly higher than traditional products, its ultra-long service life, extremely low maintenance requirements, and saved installation costs make its comprehensive cost-effectiveness clearly superior to other solutions. Furthermore, its lack of scrap value effectively prevents theft, further reducing subsequent management costs.
Wide Application Adaptability
The innovative design of this composite circular well enables it to adapt to various engineering environment needs. Whether in urban arterial roads, expressways, industrial parks, or residential areas, it can provide reliable performance. This wide application adaptability makes it an ideal choice for various types of municipal pipeline network 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 underground pipeline networks. 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 700×770×70 Composite Circular Well has become the mainstream choice for municipal engineering stems from its scientific dimensional design, reliable structural performance, convenient construction characteristics, and significant economy. This product not only solves the technical problems existing in traditional inspection wells but also provides a reliable solution for the construction of modern urban underground pipeline networks. Choosing this product means selecting a quality assurance and technical support for municipal engineering projects that stands the test of time, which is the fundamental reason for its continued recognition in the market competition.
