Description

Technical Field

[0001] The invention provides a technical field of engineering construction, in particular to a rotary jet anchor embolism water blocking tool and a construction method thereof. Background Art

[0002] Concrete retaining wall design is relatively common, such as diversion hole plugging, concrete cofferdam, etc. In the construction of concrete retaining wall, due to external environmental reasons or internal material stress during the setting process of concrete, small cracks often appear inside the concrete, resulting in local water seepage on the back of the retaining wall. As the water storage capacity of the water retaining building increases, the water seepage pressure becomes greater and greater, and the water seepage parts need to be treated in time. The local consolidation grouting method is generally used to deal with the above problems.

[0003] During grouting, it is necessary to drill holes in the water retaining wall, and water seepage needs to be prevented during drilling. In existing public technical documents, for example, the publication number "CN210368972U" discloses an auxiliary device for grouting water seepage parts of a water retaining wall, including a shell, the shell is a cavity structure, and one end of the shell is provided with an opening, and the opening can completely cover the water seepage part; when in use, the end of the shell with the opening is connected to the back water surface of the water retaining wall, and the shell and the back water surface are sealed. At this time, holes are drilled obliquely to the water seepage area around the water seepage part, and quick-setting materials that swell when exposed to water are injected under high pressure to plug the leak.

[0004] Since the vibration during drilling is relatively large, even with the use of the above-mentioned auxiliary devices, the problem of water seepage still cannot be solved. Summary of the invention
