Background
At present, an old pipeline is used as an outer sleeve (hereinafter referred to as a sleeve) in pipeline construction, a new pipeline is penetrated in the sleeve, and in order to ensure that the inner penetrated new pipeline runs stably under the gravity or/and pressure water delivery state and is not influenced by seeped underground water, grouting treatment is carried out between the sleeve and the new pipeline so as to ensure that a gap between the sleeve and the new pipeline is compact. The grouting construction method and the used construction device in the prior art mainly adopt a perforating machine and a grouting pipe, and the grouting construction method is divided into an external grouting mode and an internal grouting mode. External grouting is that a hole is vertically punched downwards at the position above the sleeve pipe and at a certain distance at each interval until the sleeve pipe (top) is penetrated to serve as a grouting hole, then after construction of the new internally-penetrated pipeline is completed, grouting is carried out on the gap between the sleeve pipe and the new pipeline by utilizing the grouting pipe and the grouting hole, and the grouting hole needs to be plugged and a grouting point needs to be backfilled after grouting is compact. The grouting construction method and the construction device are complex, and can only ensure the grouting compactness in a certain range around the grouting hole, if the distance of a new pipeline penetrating the grouting hole is long, the grouting hole needs to be arranged on the ground at certain intervals, and the compactness of the grouting is difficult to ensure at the position close to the gap between the sleeve and the new pipeline. The internal grouting is that after the new pipeline penetrating is completed, holes are formed in the same cross section from inside to outside (the top 1 and the ten-point and two-point positions 1 respectively), the high pressure is used for grouting a gap between the sleeve and the new pipeline penetrating, and after the grouting is finished, the grouting holes are plugged by using screw plugs.
