Foundation pit slope collapse prevention pre-alarm device
The invention discloses a foundation pit slope collapse prevention pre-alarm device, and relates to the technical field of foundation pit construction. Comprising a touch switch and a pre-alarm system, the touch switch is electrically connected with the pre-alarm system, the portion, arranged in a soil body, of an anchor rod is provided with anchor thorns or fixed through grouting, the portion, exposed out of the soil body, of the anchor rod is provided with threads, the touch switch is installed at the exposed thread end of the anchor rod, and an anchor backing plate is arranged between the touch switch and the soil body. The device can be installed on a foundation pit slope and is perpendicular to a slope soil body theoretical slip plane, in the slope soil body stress release process, soil body deformation displacement enables the anchor rods in the soil body to be pulled to be connected with a circuit so as to trigger a pre-alarm device on the outer side of a foundation pit, foundation pit constructors have sufficient escape time, and the safety of the foundation pit constructors is improved. Therefore, personal casualty accidents caused by slope collapse are effectively avoided.
本发明公开了一种基坑边坡防坍塌预报警装置，涉及基坑施工技术领域。包括触碰开关和预报警系统，触碰开关和预报警系统电连接，锚杆打设在土体内部分设置锚刺或注浆固定，所述锚杆露在土体外的部分设有螺纹，所述触碰开关安装在锚杆的外露螺纹端，在所述触碰开关与土体之间设有锚垫板。本发明可安装在基坑边坡上，与边坡土体理论滑移面垂直设置，在边坡土体应力释放过程中，土体变形位移使土体内锚杆受拉接通电路，以触发基坑外侧预报警装置，使基坑施工人员有充足的逃生时间，从而有效避免边坡坍塌造成人身伤亡事故的发生。
