The invention provides a construction method for long and narrow crack renovation, and relates to the field of construction. The construction method comprises the steps that a roadbed is detected, the position of a long and narrow crack in the roadbed is determined, and the width of the long and narrow crack is smaller than a preset threshold value; constructing a first through hole according to the position of the long and narrow crack; a grouting assembly extends into the long and narrow crack from the first through hole, and slurry is injected into the long and narrow crack till the top space of the long and narrow crack is filled with the slurry; the top space is located at the top of the long and narrow crack, and the distance between the top space and the roadbed top face is smaller than a preset threshold value. According to the construction method, the amount of the slurry needing to be filled can be reduced, and the filled slurry does not influence underground water in the deep layer of the roadbed, so that the possibility that the filled slurry blocks a seepage channel of the underground water is reduced, and the adverse effect on the environment is reduced.
Description
technical field [0001] The invention relates to the field of construction, in particular to a construction method for regulating long and narrow cracks. Background technique [0002] In the karst-developed area, the cutting section is easy to dissolve and produce narrow and long cracks. Some narrow and long cracks are close to the top surface of the subgrade, which may cause cracks or breaks on the top surface of the subgrade under the action of external force, and such long and narrow cracks need to be rectified. [0003] The related construction method of narrow and long fissures fills the narrow and long fissures with slurry, so that the slurry fills the narrow and long fissures. This construction method requires a large amount of slurry to be filled, and may block the seepage channel of groundwater, causing environmental damage. Negative Effects. Contents of the invention [0004] The invention provides a construction method for regulating narrow and long fissures, w...
