Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to a simple device for secondary screening of cement slurry used in grouting operations. Background Art
[0002] In recent years, with the rapid development of my country's economy and urban construction, especially the construction of the Guangdong-Hong Kong-Macao Greater Bay Area as a key strategic planning and development center of the country, various infrastructure construction is being rapidly constructed. Among them, various composite foundation treatment constructions involving deep soft and complex geological conditions play an important role in the construction of urban infrastructure.
[0003] Traditional composite foundation treatments such as cement mixing piles and high-pressure jet jet piles are all done by hydraulically injecting cement slurry into the soil layer and mixing it with the soil to form piles or by jetting high-pressure cement slurry to form piles. The common and key point is that the cement slurry mixed with different water-cement ratios needs to be smoothly injected into the soil layer through the slurry pipeline. How to ensure the transportation and successful injection of cement slurry is the top priority of pile foundation composite foundation reinforcement treatment.
[0004] Traditional cement slurry adopts a two-stage mixing method. The first stage is a high-speed mixer for feeding, and then flows into a second-stage low-speed mixer or a slurry storage tank through a single screen, and finally pumped and slurried through a slurry suction cage. Due to the lack of a secondary screening between the low-speed mixing slurry storage tank and the pumping and slurrying process, many larger particles, impurities, and cement blocks will be sucked into the pipeline, causing the pipeline or nozzle to be blocked and reworked. Impurities will cause the temporary deployment of the screen to be blocked, requiring manual cleaning, resulting in a decrease in the filtering effect. Subsequent maintenance work has caused a lot of waste of manpower, machinery, and materials. It has also seriously affected the construction quality of the soft soil foundation pile foundation composite foundation reinforcement treatment, and there are considerable quality risks and hidden dangers, which are even more serious.
