Embodiment Construction
[0017] The south anchor of the south branch of the Huangpu Bridge on the Pearl River is located on the south bank. It is a gravity anchor. The ground connection wall adopts a circular structure with an outer diameter of 73m, an inner diameter of 70.6m, and a wall thickness of 1.2m. The underground diaphragm wall is divided into 50 groove sections with two groove shapes in total, and the overlapping length of the groove sections between Phase II and Phase I is 0.25m. The method for connecting groove sections in the construction of the underground diaphragm wall of the south anchorage of the Huangpu Bridge on the Pearl River includes the following steps:
[0018] ① if figure 1 , figure 2 As shown, build the guide wall and construction platform: build an "L" shaped reinforced concrete structure guide wall 1 on the inner and outer sides of the location 2 of the underground diaphragm wall on the ground 4, and set a reinforced concrete construction platform 3 with a certain thickn...
