Concrete hose is a special hose used in construction projects to transport highly abrasive materials such as concrete, cement slurry, mortar, etc. It is mainly connected to the end of equipment such as concrete pump trucks and concrete placing machines to achieve flexible pouring. 1. Structure; adopts a multi-layer composite structure: Inner layer: highly wear-resistant synthetic natural rubber), smooth surface to reduce resistance; Reinforcement layer: multi-layer steel cord to improve compressive strength; Outer layer: anti-aging rubber, suitable for -30℃ to +100℃ environment. Main application scenarios: Pump truck end placement: connect steel pump pipe to achieve on-site pouring of high-rise buildings, bridges, etc.; Ground pump/vehicle pump: transport concrete to narrow or remote work areas. Tunnel wet spraying support: cooperate with wet spraying machine to transport quick-setting concrete; Pile foundation grouting: drill rig grouting pipe to reinforce the foundation; Water conservancy project: cement mortar transportation operation specifications for dams and channels: Pump water to lubricate the pipeline before starting, and then inject mortar or cement slurry for pre-lubrication; It is strictly forbidden to bend the hose beyond the limit (bending radius ≥ 1 meter) to prevent pipe bursting; If the shutdown exceeds 30 minutes, the pump must be started at intervals to avoid concrete solidification.
