Proyecto de protección de túneles | Servicio de instalación de cintas transportadoras con paredes laterales antiadherentes de caucho QBF

Recently, the engineering service team from QBF rubber was dispatched to a tunnel project site and successfully completed on-site installation guidance for the sidewall conveyor belt. Supported by one-stop full-process technical services, the project’s conveying equipment achieved stable commissioning and high-efficiency operation.

Tunnel construction presents tough site conditions, featuring steep conveying angles and considerable risks of material back-sliding and spillage. Breaking away from the traditional product-only supply model, QBF rubber provides a full-chain custom service package for this project. The service scope includes preliminary site survey, working-condition analysis, custom belt selection and design, bespoke belt manufacturing, on-site hot-splicing joint execution and full-cycle installation technical guidance. This complete set of services fully meets the operational demands of steep-angle material handling for tunnel construction.

Shield tunnel jobs have tight working spaces, limited on-site manoeuvring, high muck volumes and wet excavated spoil. These conditions commonly cause spoil and fines to stick and pile up on conveyor belts. For this project, QBF rubber Anti-stick Sidewall Conveyor Belt was selected to tackle such field-proven issues. The belt’s special surface treatment resists sticking and enables good self-cleaning capability. It keeps damp tunnel muck and fine sand from clinging to the belt surface, helping avoid common problems triggered by material build-up: belt mis-tracking, slippage, faster-than-normal wear and reduced conveying capacity. Built with heavy-duty sidewalls and cleats, the belt is robust in structure, offers high tensile properties and holds up well against abrasion. It runs reliably for both vertical and steep inclined conveying work, cutting down significantly on material fallback, spillage and leakage. This brings tangible savings in on-site cleaning work and lowers the frequency of equipment maintenance.

Having expanded from standalone product supply to end-to-end technical services, QBF rubber keeps addressing practical tunnel conveying challenges through professional, custom-built solutions. Moving ahead, QBF rubber will keep focusing on shield-tunnel muck transport and steep-angle material handling applications. Continuous upgrades to product performance and service frameworks will deliver reliable support for the efficient, eco-friendly and safe running of more engineering projects.
