An integrated structure system for shallow reinforcement of expansive soil slope and monitoring and early warning of service status, including anchor cable anode structure, drainage cathode structure, moisture monitoring structure, stress monitoring structure, DC stabilized power supply, controller and wire; anchor cable anode structure Including anode tube, hard insulating sleeve, anchor cable and anchor head; anode tube includes multi-section anode branch pipe and insulating connecting pipe fittings. The invention also provides a construction method of an expansive soil slope shallow layer reinforcement and service state monitoring and early warning integrated structure system. The present invention not only considers the fact that the shallow layer of the expansive soil slope is prone to instability and landslide, but also reinforces it with anchor cables; it also considers that the deep layer of the expansive soil slope is caused by excessive water content after rainfall , and timely electro-osmotic drainage control measures for the shallow layer of expansive soil slopes; also considered for some major expansive soil slope projects, long-term monitoring of their service status, in order to issue early warnings and forecasts of landslides and other engineering disasters in time.
Description
technical field [0001] The invention belongs to the technical field of slope landslide prevention and reinforcement, in particular to an expansive soil slope shallow layer reinforcement and service state monitoring and early warning integrated structural system. Background technique [0002] In recent years, with the deepening of national highway network planning and medium- and long-term railway planning, the infrastructure construction of traffic engineering has developed rapidly. According to design and construction needs, many projects will inevitably exist in expansive soil areas, thus forming various types of expansive soil slopes and engineering slopes. Affected by the special mechanical properties and engineering characteristics of expansive soil for a long time, various types of expansive soil slope instability and landslide disasters are common. In particular, the lack of understanding and limited response to shallow landslides on expansive soil slopes. Compared ...
