Container House Drainage Problems

Drainage problems in container houses can be resolved through reasonable design, standardized construction, and regular maintenance.

I. Common Drainage Problems and Their Causes

1. Gutter Blockage: Debris such as leaves and dust can easily accumulate in gutters, leading to poor drainage or even backflow of water. For example, after heavy rain, walkways in container houses at the Nagoya Asian Games Village experienced water accumulation, partly due to inadequate gutter design or cleaning.
2. Aging of Waterproof Materials: Aging of waterproof pads on roof fasteners, the use of substandard waterproof materials during construction, or a decline in the sealing performance of the house due to aging can all lead to leakage.
3. Structural Deformation: The panels of movable houses may deform due to wind loads, snow loads, or thermal expansion and contraction, causing cracks at the joints to expand and damaging the original waterproof layer.
4. Design Flaws: Lack of slope in the transverse direction of gutters, unreasonable design of outlets, or inadequate anti-corrosion measures leading to rust and blockage can all exacerbate drainage problems.

II. Targeted Solutions

1. Optimize Gutter Design: Utilize patented technology (such as the frame components of Haoshi Integrated Housing) to automatically clean debris from gutters using cleaning bristles and moving mechanisms, preventing blockages. Ensure that the transverse slope of gutters is reasonable and that the position of outlets is scientifically determined.
2. Select Compliant Materials: Choose steel frames with an anti-wind rating of at least Level 8 according to the national standard GB/T 19001, materials with a fire rating of at least B1, and adopt prefabricated assembly processes to reduce on-site splicing gaps and improve overall sealing performance.
3. Enhance Structural Stability: Avoid walking on the roof, regularly inspect the condition of fasteners, and promptly replace aging waterproof pads. Reinforce the panels of movable houses to prevent deformation from damaging the waterproof layer.
4. Improve the Drainage System: Refer to same-floor drainage technology and set up secondary drainage outlets inside container houses to prevent water accumulation in the sink. At the same time, use HDPE pipes instead of PVC pipes to reduce the risk of leakage caused by pipe aging or loose joints.

III. Maintenance and Management Recommendations Regularly clean debris from gutters and roofs and inspect the condition of waterproof materials; check for structural damage and water ingress into electrical circuits after heavy rain; establish an emergency response mechanism to ensure that personnel are allowed to return only after risks have been eliminated.
