Intermediate Pipe Jacking Method

What Does Intermediate Pipe Jacking Method Mean?

中间管起床方法使用空气锤的熔断器通过地球驱动管道，而管道的部分由千斤顶支撑。管道的前缘通常是打开的，通常仅在安装较小的管道时关闭。这种形状允许小的过度来缓解管和土壤之间的摩擦，从而减轻管道上的应变。

This directs the soil into the pipe itself, filling it with the bore’s spoil. Special equipment attached to the pipe prevents the spoil from sticking to the pipe, and the spoil is removed after the section of pipe is in place.

Trenchlesspedia Explains Intermediate Pipe Jacking Method

In intermediate pipe jacking, the forward sections of pipe are supported by large, heavy-duty jacks placed under the middle of the pipe in the intermediate area of the pipe, but not at the ends. A specialized air hammer then begins to rain blows on the trailing edge of the pipe, driving it into the earth.

由于管道的后缘靠近孔，降低了千斤顶，并将管道的最后一部分连接到第一部分（请记住，这是一个rehab过程，而不是初始安装）。

The subsequent or last (if it's a small repair) section of pipe isn't supported by jacks; rather, after its leading edge is attached to the pipe already in the bore, its trailing edge rests on the cradle in the launching pit. It's driven into the bore while crew members clear the spoil from the forward section of pipe.
