Method for reinforcing open caisson and existing channel
The invention discloses a method for reinforcing an open caisson and an existing channel. The method comprises the following steps that S100, a plurality of first bottom sealing piles and a plurality of second bottom sealing piles are installed at the bottom of a foundation pit, and the first bottom sealing piles are located on the peripheries of the second bottom sealing piles; S200, concrete pipe piles are installed on the second bottom sealing piles along the preset positions; S300, open caisson side walls are installed on the first bottom sealing piles; and S400, high-pressure jet grouting piles are installed between the open caisson side walls and the existing channel, so that the high-pressure jet grouting piles are in lap joint with the existing channel and the open caisson side walls. By applying the method for reinforcing the open caisson and the existing channel, the water and soil pressure on the outer side of the foundation pit can be resisted, and a working space is provided for connecting a subsequent newly-built main body channel structure with the existing channel.
本发明公开了一种沉井与既有通道间的加固方法，包括如下步骤：S100，在基坑底部，安装多个第一封底桩和多个第二封底桩，第一封底桩位于第二封底桩的外围；S200，沿预定位置，在第二封底桩上安装混凝土管桩；S300，在第一封底桩上安装沉井侧壁；S400，在沉井侧壁和与既有通道之间安装高压旋喷桩，使得高压旋喷桩搭接既有通道和沉井侧壁，应用上述沉井与既有通道间的加固方法，能够抵挡基坑外侧水土压力，为后续新建主体通道结构与既有通道连接提供工作空间。
