Problems solved by technology

And for the problems not found in the inspection process, it will not be dealt with
Due to the limitations of inspection methods and quality evaluation standards, some problems in inspection wells cannot be discovered in time, resulting in incomplete repair work and unable to fundamentally solve hidden dangers in inspection wells
Even the inspection well repaired in a short period of time may be repaired again, resulting in repeated construction, which not only indirectly increases the repair and use costs of inspection wells, but also affects the use of municipal pipe networks and the normal passage of vehicles to a certain extent.

Embodiment

[0028] Such as figure 1 As shown, a non-excavation inspection well all-round repair method, at least includes the following steps:

[0029] The steps are as figure 2 As shown, a number of grouting holes 3 protruding into the surrounding soil of the inspection well are opened on the wall 1 and bottom 2 of the inspection well; the depth H of the grouting holes 3 is 0.5~1m.

[0030] Step two as figure 2 As shown, Portland cement is used as the grouting material, injected from the grouting hole 3, and the soil around the well wall 1 and the well bottom 2 is grouted and reinforced. It not only fills the hole area that may exist in the soil around the well chamber; moreover, the interaction of grouting materials between different grouting holes can play the role of the soil around the lock column. On the premise of strengthening the foundation, it can also Prevent soil movement, improve the overall performance of the inspection shaft and the ability to resist damage.

Abstract

The invention relates to the field of municipal engineering, and particularly discloses a non-excavation inspection wheel comprehensive repairing method. The non-excavation inspection wheel comprehensive repairing method comprises the steps of grouting reinforcement for a soil body, local leakage checking and stoppage, comprehensive surface spray repairing, and the like. According to the non-excavation inspection wheel comprehensive repairing method, an inspection wheel is comprehensively reinforced and repaired, the repairing effect is good, and the service life of the inspection well and corresponding pipe networks is effectively prolonged.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a non-excavation inspection well all-round repair method. Background technique [0002] The inspection well of the municipal pipe network plays an important role in the process of pipe network connection, pipe network inspection, pipe network maintenance, pipe network cleaning, pipe network repair, etc. The service life of the inspection well determines the life of the pipe network to a certain extent . The overall quality of the inspection well is generally affected by factors such as construction technology, construction quality, road construction and vehicle walking. In the middle and later stages of the service life, there will be various problems affecting the normal operation of the inspection well, mainly including: the hole wall is caused by the movement or collapse of the surrounding soil, the overall sinking of the inspection well due to the movement or collapse of...
