Abstract
The invention discloses an air pressure loading device and a rapid consolidation method for blowing-filling sludge in a yard containing straws, belonging to the field of foundation treatment.
Description
Technical Field
The invention relates to the field of foundation treatment, in particular to a pneumatic loading device for yard hydraulic filling sludge containing straws and a rapid solidification method.
Background
The method is characterized in that a large amount of high-water-content dredging sludge is generated every year in the river dredging of China, and the dredging sludge is placed in a storage yard for storage yard treatment, so that the method is an important treatment mode for the dredging sludge at present. In order to save land resources, increase the storage amount of yard sludge and convert the yard into a usable foundation as soon as possible, the yard sludge is generally required to be treated. However, the existing disposal method for the yard hydraulic filling sludge has more problems.
Firstly, the intensity of the dredged sludge is almost zero, so people and equipment can hardly be directly used for treatment and construction. Secondly, the existing common vacuum preloading technology for treating high-water-content hydraulic filling sludge belongs to a negative pressure treatment technology, and the treatment effect is poor due to the phenomena of clogging and the like during the treatment.
Many existing researches show that the effect of the positive pressure consolidation treatment on the dredger fill sludge is far better than that of a negative pressure consolidation treatment method. In the indoor test, a mode of loading on the surface of the sludge is often adopted to measure the discharge of water in the sludge, but in an actual storage yard, the sludge cannot be stacked on the surface of the sludge at all because the strength of the sludge is extremely low.
On the other hand, crop straws are one of the main wastes in agricultural production, and about 97 percent of straws in the whole world are burnt, stacked and abandoned at present, which causes great damage to the environment. Nearly half of China's soil is covered by haze, and 104 cities belong to heavy pollution, and an important reason causing haze weather is related to the incineration of rural straws, and how to better recycle the straws is also a problem which needs to be solved at present.
