Expansive soil slope supporting anchor rod based on dry-wet cycle technology and supporting method
The invention relates to an expansive soil slope supporting anchor rod based on a dry-wet cycle technology and a supporting method. The supporting anchor rod comprises an anchor rod body, a water quantity adjusting device and a control device. The anchor rod body is provided with a pressure detection device used for detecting confining pressure applied to the anchor rod body by surrounding soil when the water content of the surrounding soil changes and sending the confining pressure to the control device. The control device is connected to the pressure detection device and the water volume adjusting device and used for receiving the confining pressure sent by the pressure detection device and correspondingly controlling the water volume adjusting device to act according to the confining pressure. Wherein when the water content of the surrounding soil body is increased, and the confining pressure is larger than a preset value, the water volume adjusting device absorbs and stores the water of the surrounding soil body; when the water content of the surrounding soil body is reduced and the confining pressure is smaller than a preset value, the water volume adjusting device drains water to the surrounding soil body. The supporting anchor rod can adapt to the change of the water content of the surrounding soil body, deformation of the supporting anchor rod due to overlarge confining pressure is avoided, high supporting capacity can be maintained, and then the soil body is effectively supported and rammed.
本发明涉及一种基于干湿循环技术的膨胀土边坡支护锚杆及支护方法，支护锚杆包括锚杆本体、水量调节装置和控制装置；锚杆本体设有压力检测装置，用于当周围土体含水量发生变化时检测周围土体对锚杆本体施加的围压并发送到控制装置；控制装置分别连接于压力检测装置和水量调节装置，用于接收压力检测装置发送来的围压，并根据围压相应控制水量调节装置动作；其中，当周围土体含水量增加导致围压大于预设值时，水量调节装置吸收并储存周围土体水分；当周围土体水分减少导致围压小于预设值时，水量调节装置向周围土体排水。能自适应周围土体含水量的变化，避免支护锚杆受到过大围压而变形，能够维持较强的支护能力，进而对土体进行有效的支护及夯固。
