Reconstruction and extension road subarea active dehydration roadbed structure and construction method
The invention discloses a reorganization and extension road subarea active dehydration roadbed structure and a construction method, an old roadbed and a new roadbed are spliced through a step excavation section, a capillary blocking layer is laid at the bottom of the new roadbed, and a plurality of layers of conductive wicking basalt fiber geotextiles are laid in the new roadbed at intervals; one end of each conductive wicking basalt fiber geotextile is embedded into the old roadbed, and the conductive wicking basalt fiber geotextiles connected with the positive electrode and the negative electrode of the direct-current power supply are alternately arranged in the vertical direction; and a time domain reflection sensor is embedded between every two layers of conductive wicking basalt fiber geotextiles at the lower part of the joint of the new road and the old road, is in communication connection with a controller of the direct-current power supply, and is used for controlling the connection or disconnection between the direct-current power supply and the corresponding conductive wicking basalt fiber geotextiles. The method has active dehydration and roadbed reinforcement composite functions, and can effectively prevent and treat frost heaving, differential settlement, frost boiling and mud rising and other diseases generated under the freezing and thawing cycle effect in the seasonal frozen region reconstruction and extension project.
本发明公开了一种改扩建公路分区域主动脱水路基结构及施工方法，旧路基与新路基之间通过台阶开挖段拼接，新路基的底部铺设有毛细阻滞层，新路基内间隔铺设多层导电芯吸玄武岩纤维土工织物，导电芯吸玄武岩纤维土工织物的一端嵌入旧路基，分别连接直流电源正极和负极的导电芯吸玄武岩纤维土工织物在竖向上交替布置；新旧路拼接处下部的每两层导电芯吸玄武岩纤维土工织物之间均埋设有时域反射传感器，时域反射传感器与直流电源的控制器通讯连接，用于控制直流电源与对应导电芯吸玄武岩纤维土工织物的连通或断开。本发明兼具主动脱水和路基加筋复合功能，能够有效防治季冻区改扩建工程中冻融循环作用下产生的冻胀、差异沉降和翻浆冒泥等病害。
