Abstract
Waterproof construction technology and quality control of underground engineering are the key links to ensure the safety and stability of underground structure and extend the service life of the project. In this paper, the importance, common techniques, construction process and quality control measures of underground engineering waterproofing construction are described, aiming at providing theoretical guidance and practical reference for underground engineering waterproofing construction. The purpose of underground engineering waterproofing is to prevent groundwater from penetrating into the interior of the project, protect the underground structure from water damage, and ensure the normal use and function of the project. The quality of waterproof construction directly affects the overall quality, safety, stability and service life of underground engineering. Therefore, it is of great significance to conduct in-depth research on waterproof construction technology and quality control of underground engineering. In terms of waterproof construction technology, this paper introduces a variety of commonly used waterproof materials, such as polymer waterproof materials, asphalt waterproof materials, cement-based infiltration crystal waterproof materials, and analyzes the performance characteristics, application scope and construction points of various materials in detail. At the same time, the key construction technologies such as the preparation and application of waterproof concrete, the laying and welding of waterproof coil, the brushing and curing of waterproof coating are discussed. In terms of construction process, this paper describes in detail every link of waterproof construction of underground engineering, including foundation pit excavation, base treatment, waterproof material laying, waterproof layer construction, detailed node treatment and waterproof layer protection. It is emphasized that the principle of "prevention, drainage, cut-off and blocking" should be followed in the construction process to ensure the continuity and integrity of the waterproof layer. In terms of quality control, this paper puts forward a number of concrete measures, such as strengthening the acceptance of material quality, improving the skill level of construction personnel, strengthening the supervision and inspection in the construction process, and implementing strict quality inspection and acceptance system. At the same time, the importance of detailed joint treatment is emphasized, and it is pointed out that these parts are often the weak link of waterproof failure and need special attention. This paper summarizes the importance and challenges of underground engineering waterproofing construction technology and quality control, and looks forward to the future development trend of waterproofing technology. With the continuous progress of science and technology and the increasing maturity of engineering technology, the waterproof construction of underground engineering will pay more attention to the application of comprehensive waterproof technology to improve the durability and reliability of waterproof layer. At the same time, strengthening quality management and technological innovation will be an important driving force to promote the continuous development of underground engineering waterproof construction.
