Environmental measures for flexible waterproof casing.1 . Production and installation of flexible waterproof casing construction of electricity, should be responsible for the installation, maintenance and management of electrical equipment and lines. Electricity equipment should be well grounded and zeroed, handheld power tools equipped with leakage protector.
2 . Processing and welding waterproofing layer in the underground structure, the operator should wear insulated gloves and insulated rubber shoes, to prevent leakage of electricity during operation.
3 . On-site gas cutting and welding to have a person to watch the fire management, welding site around 5m forbidden to stack flammable materials; fire places to prepare fire equipment, appliances and fire hydrants.
4 . Installation of steel casing, flexible waterproof casing and other components, tied firmly, lifting point should be through the location of the components, lifting should be smooth, avoid vibration or swing. Before the component is in place and temporarily fixed, do not untie the rigging or remove the temporary fixing tools to prevent falling off and injuring people.
5 . Welding operations in the basement and deep pits should be well ventilated to prevent poisoning by pharyngeal gas.
6 . In the process of construction of flexible waterproof casing channel, should be quality inspection of each process, qualified before proceeding under.
7 . The quality of the weld is the key to waterproofing, special attention should be paid to achieve a continuous full weld, no porosity slag, while also paying attention to reduce the secondary stress generated by the weld.
