Construction Precautions for Resin Concrete Drainage Channels
Resin concrete drainage channels, featuring high strength, corrosion resistance, and lightweight advantages, are widely used in municipal projects, industrial parks, underground garages, and other scenarios. Construction quality directly affects the stability and service life of the drainage system. Strict compliance with specifications is required, with a focus on the following precautions. Follow Yajing Environment to learn more!
Before construction, review construction drawings to confirm the location, slope, and dimensions of drainage channels, and verify the distribution of underground pipelines. Inspect the quality of finished channel bodies, discard damaged modules, ensure strength meets requirements, and select concrete of grade C25 or above for the foundation material.
Excavate the foundation trench according to design dimensions, compact and level the base, control the slope within 0.5%-2%, and lay a gravel cushion layer for soft soil. The base levelness must comply with specifications to avoid uneven stress on the channel body.
Join channel bodies using socket splicing, fill joints with special sealant to prevent leakage, and calibrate alignment. Backfill in layers with fine sand or graded crushed stone and compact thoroughly. After construction, clean debris, conduct water flow tests, ensure cover plates are installed flat and securely, and perform regular maintenance in the later stage to extend service life.
