Research on Waterproof Technology of Construction Engineering

Abstract

Waterproof construction is a comprehensive, practical, strong engineering, it relates to a waterproof material, waterproof engineering design, construction technology, building materials management and other parties, use function of building engineering plays a vital role. No seepage leakage, to ensure smooth drainage. The building has a good waterproof and the use of the function is the basic requirement of building waterproof technology. This paper according to the requirements were the elaboration and discussion. Keywords-Building Waterproof; Waterproof Material; Waterproof Technology I. PREFACE Waterproof construction engineering is one of the most important functions of building products, is related to the structure of the use value, use and health conditions, the influence to people's production activities, the quality of work and life, to ensure the engineering quality has an important role. With the continuous improvement of social living conditions, people pay more and more attention to their quality of life, the requirements of the waterproof conditions continue to increase. In recent years, with the development of social science and technology, the new waterproof material and its application technology are developing rapidly, and it is developing from the multi-layer to the single layer, from the hot construction to the cold construction direction.. In the face of scientific and technological progress and updating, it is important to master the construction preparation and quality of waterproof project, which is of great significance to the development of construction engineering.. Waterproof building is a comprehensive and practical engineering technology, which plays a vital role in the function of building engineering.. The poor quality of waterproof construction is the direct cause of the leakage of waterproof project.. In order to improve the quality of waterproof engineering, is more important, in the waterproof engineering design and construction, easy to cause the weak parts of the local damage should set the enhancement layer, to improve the overall ability to fortify waterproof layer, prolong the service life of the waterproof layer. Waterproof project is a systematic project, it relates to waterproof material, waterproof engineering design, construction technology, the management of buildings and other aspects of the building. Building waterproof engineering task is based on the aspects of factors, comprehensive evaluation, is selected to meet the requirements of high performance waterproof material, waterproof engineering design of reliable, durable, economical, rational, seriously organize, careful construction, improve maintenance, maintenance management system, to meet the buildings and structures of waterproof and durable years and achieve high quality of waterproof engineering and good comprehensive benefits. Waterproof engineering quality building waterproof engineering overall quality of the request is: no leakage, ensure the drainage is smooth, so that the building has a good waterproof and use function. The quality of building waterproof engineering is closely related to waterproof material, waterproof design, waterproof construction and maintenance management, so we must pay high attention to it. II. WATERPROOF TREATMENT OF BASIC LEVEL Waterproof layer is attached to the base of the main structure, its quality directly influences quality of waterproof layer, main structure and leveling layer stiffness, smoothness, strength, surface slope accurately, perfect surface, without sand up skin, joints, the basic water content is to ensure the waterproof layer construction quality, waterproof engineering quality of the foundation. The construction conditions of the waterproof layer construction condition of the main points of the weather conditions of the construction conditions or not directly related to the construction quality, waterproof engineering most open operation, the climate factors. Construction period of rain, snow and temperatures lower than 5 DEG C or higher than 35 DEG C will affect the waterproof layer construction quality, also hinder the construction workers to smooth the operation construction. Hot towel roll and solvent based coatings can be in more than 10 DEG C temperature conditions construction; asphalt; modification of asphalt and polymer membrane should not be below 0 DEG C construction; asphalt base coating, polymer emulsion coating and rigid waterproof layer, not 5 degrees below the temperature in construction; temperature more than 35 DEG C is all the waterproof layer are not construction; hot summer in the middle of the night dew, level 5 following wind sand dust weather effects and primary bonding, pollution base shall be of the waterproofing construction operation. Pay attention to the materials used in the waterproof layer of waterproof layer and the construction of relevant levels cross cutting issues must be for the purpose of ex factory quality certificate and test report sheet, also at the scene before use must to do waterproof test, qualified rear can use. Associated with the waterproof layer level is the leveling layer, vapor barrier layer, insulating layer, isolation layer, protective layer etc.. The construction of waterproof layer often cross operation with related layers, the construction quality of these levels has a great influence on the quality of waterproof layer, International Conference on Chemical, Material and Food Engineering (CMFE-2015)
