Widened pile-plate structure for deep soft soil high-filling roadbed of expressway and construction method of widened pile-plate structure
The invention provides an expressway deep soft soil high filling roadbed widening pile-slab structure and a construction method thereof.The expressway deep soft soil high filling roadbed widening pile-slab structure is characterized in that a pavement structure layer, the widening pile-slab structure, a soft soil layer and a bearing layer are sequentially and adjacently arranged from top to bottom in the height direction of an expressway, the widening pile-slab structure comprises an original roadbed, and a side slope is provided with a plurality of steps; the widened pile-slab roadbed is spliced with the plurality of steps, the widened pile-slab roadbed comprises a cushion layer, a plurality of filler layers and an anti-settling layer which are sequentially arranged from bottom to top in the height direction of the expressway, each filler layer is correspondingly spliced with one step, and the anti-settling layer is spliced with one step, close to the pavement structure layer, in the plurality of steps; one end of the pile plate assembly is fixed to the bottom of the cushion layer, and the other end penetrates through the soft soil layer to be fixedly connected with the bearing layer; and the earthwork standard room assembly is fixed at the bottom of one end of the anti-settling layer. According to the widening pile plate structure for the deep soft soil high-filled roadbed of the expressway, differential settlement can be effectively inhibited, and the stability of the expanded roadbed is improved.
本发明提供高速公路深厚软土高填路基加宽桩板结构及其施工方法，路面结构层、加宽桩板结构、软土层和持力层依次沿高速公路的高度方向由上至下相邻布设，加宽桩板结构包括：原始路基，边坡设置有若干级台阶；加宽桩板路基，与若干级台阶相拼接，加宽桩板路基包括沿高速公路的高度方向由下至上依次设置的垫层、若干层填料层和防沉降层，每一层填料层对应与一级台阶相拼接，防沉降层与若干级台阶中靠近路面结构层的一级台阶相拼接；桩板组件，一端固定在垫层的底部，另一端穿过软土层与持力层固定连接；土工格室组件，固定在防沉降层的一端的底部。本发明的高速公路深厚软土高填路基加宽桩板结构，能够有效抑制差异沉降，提高拓展路基的稳定性。
