Large diameter metal corrugated pipe is introduced
Large-diameter metal corrugated pipe is used for installation of large equipment embedded hole, the anchor bolt with large diameter, high ripple, weight light, stiffness big, good rigor, attach the characteristics of strong pulling force, completely changed in the past with boards or low bellows as embedded material of history, is widely used in Bridges, multi-layer factory building, parking lot, write, apartment buildings, stadiums and other large buildings.
Large diameter metal corrugated pipe is spiral winding with steelskin belt of circular and oblate corrugated pipe, is easy to work, save material, equipment location accurate, stable equipment after installation is firm, etc. In modern architecture, has been developed countries such as Britain, France, the United States and Japan are widely used, its light wall thin, strong rigidity, not broken, do not leak slurry

Scope of application of large diameter metal bellows
Method of post-tensioned prestressed concrete bridge with prestressed metal bellows; Reinforced concrete hollow slab bridge with prestressed metal bellows; The reserved channel beam slab after tensioning steel strand. Because of corrugated duct tape corrugated, combined with concrete is better, and steel strand tension grouting after coagulation can make steel strand, slurry, beam slab between good combination, to ensure uniform distribution of stress and the stress losses. Anchor bolt hole with metal corrugated pipe; Based pipeline construction, building walls, embedded pipe.

Large diameter metal corrugated pipe product performance
Rigid test: 1. The resistance of concentrated load of 0.75 KN or 1.5 KN uniformly distributed load, the radial deformation of 0.1 d or less.
2. The permeability test: water or water cement ratio 0.5 slurry 30 minutes without leakage, leakage of slurry.
3. The tensile test, axial tension 5 kn wall without damage.
4. The pull-out test: embedded in the concrete pulling force of anchor bolt design more than 2.3 times the pull-out force.
5. The bending test: curvature of radius of curvature of 30 d, no leakage, leakage.
