Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] refer to figure 1 , The invention provides a pipe jacking pipeline repair method, which solves the problem that cement mortar repairing the pipeline affects the subsequent pipe jacking construction. The pipe jacking pipeline repair method of the present invention will be described below in conjunction with the accompanying drawings.
[0021] combine figure 1 with figure 2 As shown, the pipe jacking pipeline repair method of the present invention comprises:
[0022] Executing step S201: providing a first repair material. The step of providing the first repair material includes: providing bentonite and cement, and mixing the bentonite and cement at a volume ratio of 4:1 to prepare the first repair material. Then step S202 is executed.
[0023] Execute step S202: provide a second repair material, the second repair material is epoxy re...

The invention relates to a pipe jacking rehabilitation method. The pipe jacking rehabilitation method comprises the following steps of providing a first repairing material, and injecting the first repairing material into soil outside the damaged position of a pipe; providing a second repairing material, specifically, the time for solidification of the second repairing material is shorter than thetime for solidification of the first repairing material; and coating the damaged position of the pipe with the second repairing material so as to form the repairing structure for blocking the damagedposition of the pipe. The soil outside the damaged position of the pipe and the damaged position of the pipe are filled with the first repairing material and the second repairing material which need the different times for solidification, so that the repairing material in the soil is not solidified when the repairing material at the damaged position of the pipe is solidified, the pipe does not adhere to the soil when the damaged position of the pipe is rehabilitated, and subsequent pipe jacking construction is not affected.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a repair method for pipe jacking. Background technique [0002] Pipe jacking construction is a non-excavation construction method, and it is a pipeline burying construction technology that does not excavate or excavates less. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the earth away. [0003] During the pipe jacking process, the pipe is likely to rub against foreign matter such as stones in the soil, causing damage to the pipe wall. The current conventional practice is to use cement mortar to seal and repair the damaged part of the pipe wall and then continue pipe jacking. However, after the cement mortar solidifies, the pipe and the soil stick together...
