Description

Technical Field

[0001] The invention relates to a device for repairing embankment settlement and a use method thereof, belonging to the technical field of embankment settlement repair equipment. Background Art

[0002] Embankment settlement refers to the phenomenon that after the embankment is built, due to the influence of various factors, its height gradually decreases and the ground sinks. The foundation soil below the embankment will be compressed under the load of the embankment, which is a major cause of embankment settlement. If the foundation soil is highly compressible, such as soft soil, silt, etc., the settlement may be more significant.

[0003] The soft soil foundation has a high water content, a large porosity, and a weak bearing capacity. It is easy to produce large settlement under the heavy pressure of the embankment. In order to repair the embankment settlement, grouting operations are required at the cracks in the embankment to achieve the repair operation.

[0004] At present, when the embankment is inclined, the terrain of the embankment slope itself is unstable. In such an environment, people walking on the slope with a grouting pipe or continuously holding the grouting pipe to grout the cracks in the embankment are prone to accidents such as slips and falls, posing a threat to the life safety of construction workers, and causing physical fatigue, affecting work efficiency and construction quality. In addition, long grouting time is prone to precipitation and stratification, affecting the grouting effect, and the embankment settlement repair effect is not good. Therefore, we propose an embankment settlement repair device and a method of using it to solve the above-mentioned problems. Summary of the invention

[0058] S3. Use the folding structure to fold several grouting heads to form an angle adapted to the embankment crack, and insert several of the grouting heads into the embankment crack; specifically, press down the pressing column 403 and compress the first spring 405, so that the clamping plate disengages from the clamping slot 406 on the hinged plate 402. At this time, the folding plate 401 can be rotated, so that the two groups of folding plates 401 form different angles, and the multiple groups of folding plates 401 can be folded according to the crack track of the embankment slope until the shape of the overall grouting pipe 107 corresponds to the crack track. Then release the pressing of the pressing column 403 to lock the position of the grouting pipe.

[0060] S4. After starting the stirring structure to stir the mortar, start the slurry pumping structure for grouting construction. Then start the second driving motor 210 to rotate in the reverse direction, and at the same time start the first driving motor 206 to operate to stir the cement slurry inside the mortar bucket 101. Finally, start the pump body 102 for grouting operation.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0062] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
