Existing slope secondary excavation safety protection device and construction method
The invention discloses an existing slope secondary excavation safety protection device and a construction method. The existing slope secondary excavation safety protection device comprises a color steel enclosure arranged at the slope toe of an existing slope and a protection wall arranged on a platform; the color steel enclosure comprises a color steel plate arranged at the slope toe; a prefabricated stand column ground beam is embedded in a soil body below the color steel plate; a steel stand column is arranged in the stand column ground beam; and the color steel plate is connected with the steel stand column. According to the existing slope secondary excavation safety protection device and the construction method, the color steel enclosure and the protection wall intercept a rock-soil body which collapses or slides down under slope secondary excavation disturbance in a segmented manner, the sliding-down distance of the rock-soil body is reduced, and therefore the sliding-down potential energy of the rock-soil body is reduced; under multiple protection measures, the problem that the rock-soil body collapses or slides down due to slope secondary excavation disturbance, and consequently the lower road traffic safety is influenced is effectively solved; and the safety protection device can be repeatedly used, the construction cost is effectively reduced, the construction period is shortened, the construction efficiency is improved, and the construction procedure is simplified.
本发明公开了一种既有边坡二次开挖安全防护装置及施工方法，既有边坡二次开挖安全防护装置包括布置在既有边坡坡脚的彩钢围蔽和布置在平台上的防护墙，彩钢围蔽包括布置在坡脚的彩钢板，彩钢板下方的土体内埋置有预制的立柱地梁，立柱地梁内设置有钢立柱，彩钢板与钢立柱相连；本发明通过彩钢围蔽和防护墙分段拦截边坡二次开挖扰动下崩落或滑落的岩土体，降低岩土体滑落的距离，从而降低岩土体滑落的势能；多重防护措施下，有效地解决了边坡二次开挖扰动造成岩土体崩落或滑落影响下部道路通行安全问题；且本发明的安全防护装置可重复利用，有效降低了施工成本、缩短了施工周期、提高了施工效率、简化了施工工序。
