Description

Technical Field

[0001] The utility model relates to the technical field of compaction grouting, in particular to a compaction grouting device. Background Art

[0002] During the construction of municipal roads and bridges, it is necessary to use a compaction grouting device to inject specific materials into the foundation or cavity through pressure. The basic structure of the compaction grouting device includes a grouting pump, a mixing barrel, a screw conveyor, a flow meter, a pressure gauge, a pipeline, etc. The cooperation of these components realizes the mixing, conveying and high-pressure injection of materials. The main function of the compaction grouting machine is to carry out foundation reinforcement, waterproofing, heat insulation and other work. When the foundation is reinforced, the soil is relatively loose. If a building is built on such land, the soil will become looser over a long period of time and the house will be difficult to stabilize. For this reason, the compaction grouting device increases the stability of the foundation by injecting reinforcement materials, making the house built on it more firm and stable. When preventing water infiltration, the building will be stable over a long period of time. During long-term use, the invasion of moisture can cause damage to the foundation and cause problems such as mold and corrosion. The compaction grouting device effectively prevents water penetration by pressing in materials such as waterproofing agents or sealants, thereby improving the waterproof performance of the building. When improving the thermal insulation performance, different buildings have different insulation requirements. The compaction grouting device can incorporate specific insulation materials according to the needs of the building to improve the thermal insulation performance of the building and achieve the purpose of energy conservation and emission reduction. However, the common compaction grouting devices on the market will generate vibrations and roars during operation, which can easily cause the device to shake. After the compaction grouting device is connected to the pipe joint, the grouting liquid force is transmitted to the pipe joint, and the pipe joint is at risk of detachment or leakage.
