目前,随着中国经济建设的蓬勃发展,密集型城市化的出现决定了中、高层建筑成为建筑工程的主要发展方向,人防及汽车高拥有量也使得城市建筑转向地下空间延伸,地下室工程项目越来越多。在地下室工程施工中,最为关键的就是施工缝防渗。对此,本文对建筑工程地下室防水施工缝渗漏防渗进行简单介绍,并根据工程实例详细探究了地下室改建工程中的施工缝防渗措施。在地下室防水施工中,必须严格掌握施工要点,保证施工质量。 At present, with the vigorous development of China’s economy, the emergence of intensive urbanization has determined that middle and high-rise buildings have become the major development direction of construction projects. Civil air defense and high vehicle ownership have also caused urban buildings to turn to underground spaces. The basement project More and more. In the basement construction, the most critical is the construction joints impermeable. In this regard, this article briefly introduces the seepage prevention and leakage prevention of waterproof construction joints in the basement of a construction project, and explores the seepage control measures of construction joints in the basement rebuilding project in detail according to the project examples. Waterproof construction in the basement, we must strictly grasp the construction points to ensure the construction quality.
