Description

Technical Field

[0001] The utility model relates to construction equipment for dam reinforcement and anti-seepage, in particular to a self-lifting and regulating continuous wall-forming mixing construction method machine. Background Art

[0002] At present, the embankments of rivers and lakes in China are in urgent need of rectification, reinforcement and anti-seepage maintenance, especially the anti-seepage maintenance and reinforcement of water conservancy embankments. Therefore, improving the anti-seepage reinforcement technology of water conservancy embankments is of great significance to water conservancy projects.

[0003] At present, the anti-seepage construction equipment for dams is mainly three-axis and five-axis, which are mainly connected into walls through multi-axis vertical drilling and mixing; they are not continuous walls, and the anti-seepage effect is not good; they have strict requirements on the soil quality of the dam body. Once there is backfill soil, large stones, etc. in the soil, wall cracks are very likely to appear, causing leakage; at the same time, the equipment is constructed laterally, with a wide lateral dimension, and cannot be constructed into a wall on the dam top, and the ideal effect cannot be achieved.

[0004] As other continuous wall-forming equipment also performs lateral construction, their lateral width exceeds the dam crest width. The equipment width is generally >8M, while the dam crest width is generally 3-8M. In addition, due to their large overall weight, they cannot be constructed on the dam crest.

[0005] In the current process of reinforcing the walls of river and lake dams, it is found that the existing equipment has at least the following technical problems: 1. Since the top of the dam is relatively narrow, usually between 3-8 meters, the width of the existing wall construction equipment is usually more than 8 meters, and it is impossible to carry out construction work on the top of the dam. 2. Due to the wide equipment, sometimes it can only be operated on the dam slope, which cannot meet the requirements of anti-seepage wall construction. The anti-seepage wall construction generally requires construction on the dam top. 3. Even if construction is possible, it is a non-continuous wall equipment operation. The wall is connected by multiple cylinders, not a continuous wall. The anti-seepage effect is not good, and there is a risk of leakage at the overlap, which will cause the dam to burst after a long time. 4. If the soil conditions of the dam are not good, cracks in the wall are very likely to occur, causing leakage. 5. At the same time, the construction efficiency of the existing non-continuous wall equipment is also low. Utility Model Content
