In order to effectively improve the construction quality of composite
geomembrane, construction quality management is required, and quality management is generally guaranteed from two aspects. One is to ensure the quality of raw materials, and the other is to ensure the quality of the construction process.
1. Raw material quality control: When purchasing composite geomembrane, you must choose materials produced by regular manufacturers. When purchasing, an expert must be entrusted to conduct an on-site inspection before purchasing. In the process of purchasing materials, we must have a purchasing team and a supervision team to carry out effective procurement supervision. After the purchase is completed, fully ensure the transportation and storage of materials, avoid material damage due to other reasons, shorten the storage time and loading and unloading time of materials as much as possible, and conduct performance tests before use of materials. Therefore, relevant professional quality inspection departments can be invited to conduct experimental appraisals, and sample inspections to ensure that the materials are overall qualified.
2. Quality control during construction: In the laying of composite geomembrane, the construction must be carried out gradually in accordance with the laying principles commonly used in water conservancy projects to effectively prevent material damage caused by stress concentration in a short time and fully ensure the ideal deformation ability of the material . After the construction on the same day, in order to effectively protect the remaining unbuilt parts and prevent material damage caused by bad weather, the composite geomembrane can be temporarily fixed with soft materials such as sandbags. After further construction, the following treatments can be carried out.
