Supporting structure of pipe jacking foundation pit and construction method of supporting structure
The invention discloses a supporting structure of a pipe-jacking foundation pit and a construction method of the supporting structure, the supporting structure comprises a plurality of cast-in-place pile walls, jet grouting pile walls and a supporting assembly, the multiple cast-in-place pile walls define the pipe-jacking foundation pit, one of the cast-in-place pile walls is provided with a pipe-jacking hole, and each cast-in-place pile wall comprises a plurality of cast-in-place piles arranged side by side; the jet grouting pile wall is arranged outside the cast-in-place pile wall provided with a pipe jacking hole, and the jet grouting pile wall comprises a plurality of jet grouting piles which are arranged side by side and communicate with one another; the supporting assembly is located in the pipe jacking foundation pit and comprises a steel support and a concrete support, the steel support comprises a steel support and a steel enclosing purlin, and the steel support is connected to the inner side of the steel enclosing purlin; the concrete support comprises a concrete bottom plate and a concrete side plate, the concrete bottom plate is arranged at the bottom of the pipe jacking foundation pit, and the concrete side plate is located below the steel support. The supporting structure of the pipe jacking foundation pit has the high structural strength, the construction speed is high, the construction cost of components is lower, the cost can be saved, the construction period can be shortened, and the construction cost can be reduced.
本发明公开了一种顶管基坑的支护结构及其施工方法，支护结构包括多个灌注桩壁、旋喷桩壁及支撑组件，多个灌注桩壁围合形成顶管基坑，其中一个灌注桩壁上开设有顶管洞口，各灌注桩壁包括多个并排设置的灌注桩；旋喷桩壁设置于开设有顶管洞口的灌注桩壁外，旋喷桩壁包括多个并排设置并相互连通的旋喷桩；支撑组件位于顶管基坑内，支撑组件包括钢支撑和混凝土支撑，钢支撑包括钢支架和钢围檩，钢围檩的内侧连接有钢支架；混凝土支撑包括混凝土底板和混凝土侧板，混凝土底板设置于顶管基坑的底部，混凝土侧板位于钢支撑下方。本发明提出的顶管基坑的支护结构具有较高的结构强度，施工速度较快且构件造价更低，能节省成本和工期，降低工程造价。
