Description

Straw crushing and forming equipment
Technical Field
The invention relates to straw crushing and processing equipment, in particular to straw crushing and forming equipment.
Background
Along with the development of economy in China, the scale of building engineering and road construction is continuously increased, and the problem of processing ultra-soft foundations formed by soft soil or sludge with high water content is often encountered in construction. For example, in the hydraulic reclamation project, the surface water of the deposited sludge in the cofferdam is pumped and dried, and then natural airing treatment is generally continuously performed, because the clay content and the initial water content of the deposited sludge are high, even if the sludge is aired for several years, the surface layer of the sludge is only a crust layer with the thickness of dozens of centimeters, the overall strength is still low, the sludge is still too weak as the construction ground, and the construction machinery is difficult to enter the field to perform subsequent related operations. Therefore, the silt or soft soil is cured in situ in advance to form a cured layer of 0.5m to 1.0m on the surface of the silt or soft soil, the cured layer is prepared by adding water into cement and the silt according to a certain proportion and then mixing and stirring, the strength of the cured layer is increased along with the increase of time (age), and finally a cured crust is formed on the surface of the silt. The solidified layer can provide an effective construction operation surface for subsequent foundation treatment means, so that construction machinery can smoothly enter and exit a construction site through the sludge crust layer.
The existing problems still exist in that the hard shell layer after in-situ curing can bear enough pressure but can not bear larger tensile force, and the hard shell layer is easy to longitudinally break, so that the operation of engineering machinery is influenced. Experimental research shows that the problem can be effectively solved by adding the fiber medium into the solidified layer, the principle is equal to that of a steel bar in reinforced concrete, and the fiber medium provides a tensile medium for the solidified layer. Straw is used as solid waste, the environmental problem generated by burning is increasingly obvious, the straw is a good resource, for example, the straw is used as a filler after being crushed and is stirred with cement and soil to form cement-straw solidified soil, the straw can play the roles of water absorption, framework, lightening and reinforcement in the cement-straw solidified soil, and the strength and the integral bearing capacity of the formed soil body of the working face can be further improved.
Although cement-straw solidified soil is currently conceived, no straw processing equipment for the solidified soil exists, so that the concept only stays in the experimental stage, and a straw crushing device is developed for the purpose of being conveniently applied to sludge solidification and being claimed.
