Technical Field
The utility model relates to a dam gravel soil material preparation device and process. Belongs to the technical field of modification processing of gravel soil core wall seepage-proofing materials.
Background
The gravel soil core wall rock-fill dam is a typical local material dam, is one of dam types widely adopted in countries in the world at present, and occupies a large proportion in a 300 m-level dam.
The specifications of the natural building material survey regulations for hydropower engineering (D L/T5388) and the rolling earth-rock dam design regulations (D L/T5395) and the like define that the gravel soil refers to wide-grade gravel soil with the mass of particles with the particle size of more than 5mm accounting for 20-60% of the total mass, generally, the more coarse particles in the soil are beneficial to achieving higher density, shear strength and other mechanical properties and avoiding excess pore water pressure but are unfavorable to seepage-proofing performance, conversely, the more fine particles in the soil are beneficial to achieving higher density, shear strength and other mechanical properties and dispersion of the pore water pressure, the specification of the earth-rock dam seepage-proofing soil quality requirement is that 1) the maximum particle size is not more than 150mm or not more than the rolling earth-rock dam layer thickness 2/3, 2) the particle content is more than 20-50%, 3) the content is not more than 0.075mm, and the content of the particles is not more than 0.005% of the gravel soil is strictly required to achieve seepage-proofing.
At present, many gravel soil core wall dams in China are built by local materials, due to different geological causes, gravel soil materials are not easy to obtain directly, the gravel soil dams are formed by blending the local soil materials with certain gravel materials, and even the gravel soil materials with insufficient natural water content need to be added with water to adjust the water content. Therefore, for large and medium sized gravel soil core wall dams with high filling strength, a soil processing factory needs to be arranged for processing and modifying the coating or piling and preparing natural finished soil materials. In practical engineering, the material is generally prepared by mechanically spreading and stacking materials or directly feeding a belt conveyor into a storage bin for stacking materials.
Mechanical flat stacking refers to dumping and stacking of finished soil materials in a field by an excavator or a loader in cooperation with a self-dumping car, a bulldozer and the like. However, the method can lead the gravel soil to be repeatedly rolled before feeding, and the mechanical property index of the soil is difficult to accurately control.
The direct warehousing and stacking of the adhesive tape machine can avoid the disturbance of the back-and-forth walking of mechanical equipment to the gravel soil, but the height of the adhesive tape machine is generally higher due to the volume of the prepared material pile, so that the discharging height is larger, and the wide-graded gravel soil is easy to segregate in the material pile.
The piling, material preparation and supply of the gravel soil core wall material are key factors for restricting the filling strength of the dam, and the mechanical flat-laying and material stacking, adhesive tape machine warehousing and material stacking and the like which are actually adopted by the current soil processing factory have certain defects, and mainly have the following surfaces:
