Roadbed widening structure and roadbed widening method
The invention provides a roadbed widening structure and a roadbed widening method, and belongs to the technical field of roadbed engineering. The roadbed widening structure comprises first filling members, a baffle pile, second filling members, a geogrid and a third filling member; the multiple first filling members are stacked along a first step face preset on an old roadbed and arranged on the outer side of the old roadbed, and a second step face is formed on the outer sides of the multiple first filling members; the baffle pile is arranged on the outer side of the second step face and is connected with the roadbed and a bottom cushion layer or the lower-layer first filling member; the geogrid is laid at the bottom of the outer side of the baffle pile, and one end of the geogrid is bentto form a side slope cavity; the third filling member is arranged in the slope cavity; the plurality of second filling members are tidily arranged above the geogrid; and the side slope of the new roadbed is formed by the outer side end of the side slope cavity. Due to the fact that the geogrid is connected with the second filling member and the side slope cavity is formed by bending the end of thegeogrid, the reinforcement effect is achieved, the slope brushing procedure can be reduced, and the construction efficiency can be improved conveniently.
本发明提供了一种路基加宽结构及路基加宽方法，属于路基工程技术领域，包括第一填筑构件、挡板桩、第二填筑构件、土工格栅以及第三填筑构件；若干第一填筑构件分别沿预设在老路基的第一台阶面叠摞，并设在老路基的外侧，且若干所述第一填筑构件的外侧形成第二台阶面；挡板桩设置在第二台阶面外侧与路基及底部垫层或下层第一填筑构件连接；挡板桩外侧底部铺设土工格栅，且一端弯折形成边坡腔；第三填筑构件设置在所述边坡腔内；若干第二填筑构件在土工格栅上方整齐放置；若干个边坡腔外侧端形成新路基的边坡，由于土工格栅与第二填筑构件连接，且边坡腔为土工格栅的端部弯折而成，从而起到加筋作用，且能够减少刷坡工序，便于提高施工的效率。
