Preparation work before the construction of waterproof casing.
The manufacture of waterproof casing is an important factor directly related to the quality of construction. In the installation process of waterproof casing, it is necessary to strictly refer to the material table for manufacturing, which can not only ensure the standard, scale and length of waterproof casing, but also make the waterproof wing ring and the diameter and thickness of the flange gland more suitable for the requirements of practical construction. Not only that, the wing ring welding quality control is also essential to avoid the occurrence of leakage or pinhole holes present quality problems. In addition, in the casing and waterproof wing ring manufacturing is completed, but also to remove rust and corrosion treatment. When the manufacturing work is completed, the manufacturing quality of the flexible waterproof casing inside the retaining ring should be further checked to ensure that the scale and standard of the retaining ring are in line with the actual planning requirements. With regard to the preparation of waterproof casing construction, the construction personnel should have an adequate knowledge of the planning drawings, and the personnel concerned should keep the planning drawings in mind and have the general structure in mind. Fully grasp the standards and requirements related to the construction of waterproof casing, you can pick the right time to arrange construction construction units, planning units and supervision and management departments to review the planning drawings. Once any problems are found in the review, the project manager should promptly arrange for the person in charge of the construction plan to be prepared from scratch to ensure that similar problems do not arise when construction is carried out. Prepare a good construction plan, after reviewing the access to the waterproof casing installation work, so that the construction personnel in strict accordance with the construction plan to lay the foundation for the work. In addition, the arrangement of construction personnel out of the field to adopt a scientific and reasonable method, whether the construction personnel hold the appropriate construction qualification certificate to check, there is no relevant certificate of operators, can not be allowed to participate in the installation construction process, so as not to lead to various problems.
