Roadbed filling method for reconstruction and extension of road in road area limited section
The invention discloses a roadbed filling method for road area limited section road reconstruction and expansion, which comprises the following steps: carrying out step digging treatment on an old roadbed slope to be reconstructed so as to form a step surface, and connecting a new roadbed with the old roadbed through the step surface; a concrete baffle is installed on the outer side of the old roadbed, a pouring area is formed between the concrete baffle and a slope of the old roadbed, and the concrete baffle is made of construction waste recycled aggregate concrete; the pouring area is filled with bubble mixed light soil in a pumping mode, and a new roadbed is formed after the bubble mixed light soil is solidified; a layer of HDPE anti-seepage geotextile is laid on the bottom foundation of the pouring area, and a layer of HDPE anti-seepage geotextile is also laid on the uppermost layer of the bubble mixed light soil. The method is particularly suitable for roadbed filling of road reconstruction and extension projects when the road area width is limited, the volume weight of the bubble mixed light soil is extremely small, and most of the bubble mixed light soil is lighter than water, so that the additional load of the foundation is greatly reduced, and the treatment difficulty of the original foundation is reduced.
本发明公开了一种路域受限段道路改扩建用路基填筑方法，包括步骤：对需要改建的旧路基边坡进行挖台阶处理，进而形成台阶面，新旧路基通过台阶面连接；在旧路基外侧安装混凝土挡板，混凝土挡板与旧路基边坡之间形成浇筑区域，其中混凝土挡板采用建筑垃圾再生骨料混凝土制成；采用泵送的方式将气泡混合轻质土填筑在浇筑区域内，气泡混合轻质土固化后形成新路基；在浇筑区域的底部地基上铺设一层HDPE防渗土工布，在气泡混合轻质土的最上层也铺设一层HDPE防渗土工布。本方法尤其适用于路域宽度受限时道路改扩建工程路基填筑，由于气泡混合轻质土容重极小，大多数轻于水，极大的降低了地基的附加荷载，减小了对原地基的处理难度。
