Safety protection structure for trench excavation
The invention relates to the field of building construction protection, in particular to a trench excavation safety protection structure which comprises nail rods located beside a trench and tamped into the deep position of a soil layer, a plurality of breast boards are tightly attached to the side wall of the trench, and rod rolling assemblies used for rolling the nail rods are arranged on the breast boards; the pull rod assembly comprises an arc-shaped pull pipe, two pipe penetrating holes are formed in the soil retaining plate, the two ends of the pull pipe penetrate through the opposite side of the soil retaining plate from the side, tightly attached to the groove, of the soil retaining plate in a sliding mode through the pipe penetrating holes, and the nail rod is located in the area defined by the pull pipe and the soil retaining plate; one end of the pull pipe is detachably connected with a pipe dredging piece, the pipe dredging piece comprises an elastic rod extending into the pull pipe, a plurality of pushing pieces are spirally distributed on the outer side wall of the elastic rod in the length direction of the elastic rod, and a handle is arranged at the end, located outside the pull pipe, of the elastic rod. The mining protection device has the effect of playing a role in protecting personnel in the mining process.
本申请涉及建筑施工防护领域，尤其是涉及一种沟槽开挖安全防护结构，包括位于沟槽旁且夯入土层深处的钉杆，沟槽的侧壁紧贴有多个挡土板，挡土板上设置有用于挽过钉杆的挽杆组件；挽杆组件包括呈圆弧状的挽管，挡土板上开有两个穿管孔，挽管的两端通过穿管孔从挡土板紧贴沟槽的一侧滑动穿过至相背的另一侧，钉杆位于挽管和挡土板围合的区域内；挽管的一端可拆卸连接有疏管件，疏管件包括延伸至挽管内的弹性杆，弹性杆的外侧壁上延其长度方向螺旋分布有多个推片，弹性杆位于挽管外的一端设置有把手。本申请具有能够对挖掘过程中的人员起到防护作用效果。
