Solidified soil roadbed structure and preparation method thereof
The invention belongs to the technical field of roadbed filling materials in road engineering, and particularly relates to a solidified soil roadbed structure and a preparation method thereof. Aiming at roadbed treatment of high liquid limit soil, the device comprises a gravel layer, a high liquid limit soil solidification layer and a high-permeability slurry seal layer which are sequentially arranged from bottom to top. A three-layer structure of a gravel layer, a high liquid limit soil solidification layer and a high-permeability slurry seal layer is arranged. Meanwhile, a hardened surface formed after cement is solidified can effectively improve the strength of the solidified soil roadbed structure, the construction requirement is met, capillary water in natural high liquid limit soil on the ground can be prevented from rising, and a roadbed base is more stable. And due to the use of the high-permeability slurry seal layer, part of slurry can permeate into the high-liquid-limit soil solidification layer, the bonding effect is achieved, and the plate body performance of the high-liquid-limit soil solidification layer is further improved. The service life of the pavement is prolonged.
本发明属于道路工程中路基填筑材料技术领域，尤其涉及一种固化土路基结构及其制备方法。针对高液限土的路基处理，包括自下而上依次设置的碎石层、高液限土固化层和高渗透稀浆封层。通过设置碎石层、高液限土固化层和高渗透稀浆封层三层结构。保证路基的压实度，同时，水泥凝固后形成的板结面，可以有效提高固化土路基结构的强度，满足施工要求，且能够阻断地面天然高液限土中毛细水的上升，使得路基基底更加稳定。高渗透稀浆封层的使用，使得部分浆液可以渗透至高液限土固化层中，起到粘结的作用，进一步提高高液限土固化层的板体性。从而延长了路面寿命。
