Description

Technical Field

[0001] This invention relates to the field of equipment for mixing dredging and solidification materials, and in particular to an integrated device and its method of use based on the integrated mixing of dredging and solidification materials. Background Technology

[0002] In infrastructure construction fields such as road engineering, foundation treatment, and port and waterway engineering, the reinforcement of unfavorable geological conditions such as soft soil and silt has always been a key focus and challenge in engineering practice. Traditional soft soil solidification technology typically involves two relatively independent technical stages: the first is the excavation and dredging stage, which involves excavating, dredging, or drilling holes in the soft soil using excavation equipment to disturb the soil structure and create conditions for subsequent reinforcement; the second is the material mixing and preparation stage, which involves mixing solidification materials such as cement, lime, and additives with water in a fixed mixing plant or mixing equipment to prepare a fluid solidification slurry. In actual construction, these two stages are often carried out separately by different types of specialized equipment, resulting in a fragmented construction process, large equipment investment, complex process connections, and severely restricting construction efficiency.

[0003] However, the existing step-by-step operation mode has obvious technical defects. First, the dredging equipment and the material preparation and mixing equipment are spatially separated. There is a time delay from the preparation of the solidification material to its transportation to the site and injection into the excavation area, which can easily lead to problems such as initial setting and performance degradation of the material. It is difficult to ensure that the solidification material and the freshly excavated soil achieve sufficient contact and mixing within the optimal time, directly affecting the solidification effect. Second, the long exposure time of the excavated soil makes it susceptible to weather and environmental factors, further increasing the difficulty of quality control. In addition, the existing equipment has a single function and lacks a dedicated mechanism for efficiently mixing the dredged soil with the solidification material. In particular, it cannot achieve integrated and coordinated operation from deep drilling and grouting to shallow surface loosening and mixing on the same equipment, resulting in uneven reinforcement effects between deep and shallow layers, making it difficult to meet the comprehensive requirements for foundation treatment quality under complex working conditions.

[0004] In response to the above problems, in recent years the industry has begun to explore technical solutions that integrate excavation equipment and mixing equipment, but existing integrated devices still have many shortcomings.

[0005] For example, in the mixing unit, the slurry adheres to the wall and leaves residues after mixing, which not only wastes materials but also makes equipment cleaning inconvenient. In the drilling module, deep drilling and grouting operations are difficult to coordinate synchronously, resulting in poor grouting uniformity. At the same time, the loosening, crushing, grouting, and secondary mixing of shallow soil often require multiple sets of equipment to be completed, making it impossible to achieve continuous and efficient flow operations. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated device and its usage method based on the integrated mixing of excavation and dredging and solidification materials. This device can deeply integrate the functions of excavation and dredging with solidification material preparation, mixing, grouting, and leveling, so as to solve the technical problems of process separation, material waste, uneven mixing, and poor synergy between deep and shallow layers in the prior art.

[0055] Example 2

[0056] Based on Example 1, this example introduces a method for using an integrated device based on the integrated mixing of drilling and curing materials, including: Step 1: Set the curing material ratio through the control module 7, and feed the material into the first mixing unit 21 through the feeding hopper 22 and the intelligent material metering unit 23.

[0057] Step 2: The materials are mixed by stirring rod 242 in the first stirring unit 21. After the mixing is completed, scraper 2425 is removed from stirring rod 242 and rotates to contact the inner wall of the first stirring unit 21, scraping off the remaining slurry on the inner wall of the first stirring unit 21. At the same time, during the operation of stirring rod 242, scraper 2425 collides with shaking plate 26, and the slurry on scraper 2425 vibrates and falls down.

[0058] Step 3: As the deep drilling rig unit 56 moves down, the main drilling frame 561 starts, the excavation and dredging head frame 563 rotates, and the material preparation and mixing module 2 transfers the slurry to the deep drilling rig unit 56, which is then sprayed out through the grouting nozzle 5633 and injected into the excavated channel and the surrounding soil.

[0059] Step 4: The solidification mixing module 3 is started, and grout is injected into the ground through the material preparation mixing module 2.

[0060] Step 5: The solidified soil layer is compacted using the leveling and compaction module 4 to form a solidified road surface.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
