At present, there is a heat wave of expressway widening construction in China. The technical difficulties encountered in the embankment widening project may be more difficult than the new expressway construction, because there are differences in the consolidation deformation of the new and old foundations in the splicing of the new and old embankments. , such as improper handling will inevitably lead to cracking and instability of the pavement

Abstract
The invention relates to a device and a method for stirring waste soil and expanded polystyrene granule light embankment padding. The device can be utilized to quickly and uniformly stir the waste soil, EPS granule, water and curing agent, so as to form a mixed light embankment padding applied to large-area engineering construction. In the device, an EPS foaming chamber (1) is communicated with an EPS storage bin (3) through a centrifugal machine; the EPS storage bin is connected with an upper port of a stirring bin (10) through a flow meter (4); a retarder feeding port (5), a water feeding port (6), a cement feeding port (7) and a waste soil port (8) are respectively connected with the upper port of the stirring bin (10) through a weighting meter (9); a mixed light padding discharging port (11) is arranged on the stirring bin; a control instructor (12) is connected with a computer (13) and is used for respectively controlling the centrifugal machine, the flow meter, the retarder feeding port, the water feeding port, the cement feeding port, the waste soil port, the weighting meter, the stirring bin and the discharging port.
Description
technical field [0001] The invention is a kind of mixing equipment for waste soil EPS (expanded polystyrene) particles mixed with lightweight embankment filler, which can realize rapid and uniform mixing of waste soil, EPS particles, water and curing agent (usually cement) Mixing to form a mixed lightweight embankment filler for large-area engineering construction. In this way, it can save land and protect cultivated land, reduce the load on the embankment, and control the jumping at the bridge head, thereby reducing the cost of foundation reinforcement treatment for expressway projects, saving engineering investment, and has good sustainable development characteristics. Background technique [0002] In the construction of expressways, a large amount of clay is used as embankment filling materials. According to statistics, more than 6,000 mu of soil is used for every 100 kilometers of expressway construction. In the economically developed eastern region, land resources are v...
