Enclosure structure for controlling deformation of subway deep foundation pit and construction method thereof
The invention relates to the technical field of building structures, in particular to an enclosure structure for controlling deformation of a subway deep foundation pit and a construction method thereof, and the enclosure structure comprises a station shield end foundation pit enclosure structure and a standard section foundation pit enclosure structure; the station shield end foundation pit support structure and the standard section foundation pit support structure are each provided with a plurality of supporting structures which at least comprise a first supporting structure, a second supporting structure, a third supporting structure and a fourth supporting structure. The first supporting structure is connected with the continuous wall through the concrete top beam. The second supporting structure is connected with the continuous wall through a concrete waist beam; the third supporting structure is connected with the continuous wall through a concrete waist beam or a steel enclosing purlin; the fourth supporting structure is connected with the continuous wall and arranged at the bottom of the foundation pit. According to the method, the safety of controlling the deformation of the deep foundation pit support structure in the deep soft soil layer is ensured.
本发明涉及建筑结构技术领域，具体涉及一种控制地铁深基坑变形的围护结构及其施工方法，其中围护结构包括车站盾构端基坑围护结构和标准段基坑围护结构；车站盾构端基坑围护结构和标准段基坑围护结构均设置有若干道支撑结构，至少包括第一支撑结构、第二支撑结构、第三支撑结构和第四支撑结构；第一支撑结构通过混凝土冠梁连接连续墙；所述第二支撑结构通过混凝土腰梁连接连续墙；所述第三支撑结构通过混凝土腰梁或钢围檩连接连续墙；所述第四支撑结构连接连续墙并设置在基坑底部。本发明保证了深厚软土地层控制深基坑围护结构变形的安全性。
