Problems solved by technology

Among them, the vacuum preloading method is currently the most widely used method. Although this method has high processing efficiency, the processing effect is often poor, and it is difficult to meet the requirements of roads, medium and high-rise buildings, heavy factory buildings, storage areas, etc. with high engineering requirements. Foundation conditions; on the other hand, this method takes a long time to process the foundation, which will affect the development speed in the later stage, and the cost is high
In general, in order to study the mechanism of action of soft soil treatment methods and engineering technology control parameters, it is necessary to carry out systematic theoretical research and experimental research on soft soil treatment methods, but there is no report on the relevant experimental research methods and devices.

Abstract

The invention discloses a soft foundation treatment experiment device and method. The experiment device comprises an experiment box body, a vacuum water drainage system and a vacuum grouting system, wherein the experiment box body is provided with an accommodating cavity for accommodating an experiment soil body; the vacuum water drainage system mainly comprises a vertical water drainage plate, a horizontal water drainage pipe, a water drainage pipeline and a vacuum pump; and the vacuum grouting system mainly comprises a grouting pipe, a grouting pipeline and a grouting pump. According to the experiment method, the experiment device is used, an experiment method of a vacuum pre-pressing technology and an experiment method of a soft foundation grouting technology are combined, and an experiment method of a vacuum grouting composite soft foundation treatment technology is constructed. The soft foundation treatment experiment device has the advantages that in an experiment soil body treatment process, the vacuum grouting system and the vacuum water drainage system can work at the same time, the treatment efficiency is improved, and the treatment time is shortened; and effects of treating sludge with higher moisture content and small seepage coefficient and sludge foundation are very outstanding.

Description

technical field [0001] The invention relates to a soft ground treatment technology, in particular to an experimental device and an experimental method for soft ground treatment. Background technique [0002] The soft foundation for tidal flat reclamation is characterized by high water content, fine soil particles, strong fluidity, and mostly muddy soil, which has poor engineering properties. The nature of this kind of soft foundation determines that it needs to be reinforced before it can be used as the foundation of engineering construction. Although there are many methods for dealing with soft foundations, due to the large area of ​​tidal flat reclamation and high treatment requirements, many soft foundation reinforcement treatment methods are difficult to solve such soft foundation problems. At present, the commonly used soft ground treatment methods include vacuum preloading method, dynamic compaction method, sand well method, stone pressing method and so on. Among the...
