Bearings are vital components in bridges and buildings, connecting structures to transfer loads and accommodate deformations. This guide covers seven common types: laminated rubber bearings, pot bearings, spherical bearings, spherical steel bearings, seismic isolation rubber bearings, space frame bearings, and rubber pads. Each type's working principle is explained, from elastic deformation to sliding mechanisms. Key selection considerations include structural load requirements, the structural system and layout, special conditions like seismic activity or corrosion, and economy with maintainability. A proper selection ensures safety, durability, and conformity to the design.

This article introduces three common types of waterstop products: PVC waterstop, rubber waterstop, and steel-edged rubber waterstop. It describes the material composition, manufacturing process, performance characteristics, common specifications, cross-section types, and main application scenarios for each type. PVC waterstop is a plastic waterproofing material made from polyvinyl chloride resin, offering good flexibility and corrosion resistance. Rubber waterstop is an elastic waterproofing material made from natural or synthetic rubber, providing excellent elasticity and temperature adaptability. Steel-edged rubber waterstop is a composite material combining rubber and steel strips, offering enhanced anchoring performance.

The water-swelling waterstop strip is a flexible waterproofing material that actively fills and seals concrete joints by physically expanding upon contact with water. This article explains its fundamental working principle and outlines its typical applications in underground engineering, water conservancy facilities, transportation infrastructure, and industrial & civil construction. It also provides an objective overview of the key characteristics—such as expansion performance, long-term durability, installation methods, and application boundaries—that influence its effectiveness and suitability, serving as a comprehensive reference for engineering selection.

This article serves as a practical guide to PVC waterstops. It covers their definition, working principle, and details key applications in subterranean structures, water conservancy projects, tunnels, and municipal utilities. The core of the article focuses on three critical factors for selection: material properties, profile design, and installation requirements. It concludes by emphasizing that successful application relies on a comprehensive assessment of specific project joint conditions and the environment, recommending professional consultation and technical data for informed decision-making.

This article outlines the core types of bridge elastomeric bearings—laminated, pot, and seismic isolation—and explains how their flexible design manages load and movement. Using the widely applied laminated bearing as an example, it delves into the material science and structural synergy behind its function, and emphasizes the critical role of regular inspection and maintenance in ensuring long-term bridge safety and service life.

Types of Water StopsWater stops are categorized based on their material composition and the specific applications they are designed for. The primary types include PVC water stops, rubber water stops, steel-edged water stops, and water-swelling water stops.
