住宅下沉式庭院是住宅建筑发展中推出的新形式。由于下沉式庭院的竖向标高低于室外地面,因此该部分的雨水排放除了传统的重力流排放方式外,还可能需要依靠雨水排水泵的加压提升才能排除。对不同的工程情况所采用的不同排水方式的特点和问题进行了分析,期望在今后的工程中得到更合理、更有效的排水设计方式。
Residential sunken courtyard is a new form introduced in the development of residential buildings. Due to the vertical elevation of the sunken courtyard is lower than the outdoor ground, in addition to the traditional way of gravity flow discharge, this part of the rainwater discharge may also need to rely on the rain drainage pump pressure increase can be ruled out. The characteristics and problems of different drainage methods adopted in different engineering conditions are analyzed. It is expected that more reasonable and effective drainage design methods will be obtained in future projects.
