Guardrail for construction of grouted rubble retaining wall
The guardrail comprises a telescopic guardrail body and further comprises a protection mechanism, the protection mechanism comprises a cylinder body arranged on one of two adjacent hinged rods of the telescopic guardrail body, a cavity is formed in the side wall of the cylinder body, and the telescopic guardrail body is arranged in the cavity. The bottom of the cylinder body is provided with a one-way inlet valve and a one-way outlet valve which are used for communicating the interior of the cylinder body with the interior of the cavity, the interior of the cylinder body is connected with a piston in a sliding and sealing mode, non-Newtonian fluid is arranged in the cylinder body, and a piston rod is hinged to the end, away from the bottom of the cylinder body, of the piston; the end, away from the piston, of the piston rod is hinged to the other one of the two adjacent hinge rods. By arranging the protection mechanism, if a worker falls down and collides with the guardrail, non-Newtonian fluid in the cylinder body is changed into a solid under sudden impact force, sliding of the piston can be prevented, telescopic deformation of the telescopic guardrail can be prevented, and therefore the worker is prevented from falling off from the high altitude.
本发明公开了一种浆砌块石挡土墙施工用护栏，包括伸缩护栏，还包括防护机构，所述防护机构包括伸缩护栏的相邻两个铰接杆的其中一根上设置的缸体，所述缸体的侧壁上开设有空腔，所述缸体底部设置有将所述缸体内部与所述空腔内连通的单向进口阀和单向出口阀，所述缸体的内部滑动密封连接有活塞，所述缸体的内部设置有非牛顿流体，所述活塞上远离所述缸体底部的一端上铰接有活塞杆，所述活塞杆上远离所述活塞的一端与相邻两个铰接杆的另外一根铰接。本发明通过设置防护机构，若工人因摔倒撞击到护栏的时候，缸体内部的非牛顿流体受到突然的冲击力变成固体，能阻止活塞的滑动，阻止伸缩护栏的伸缩变形，从而避免工作人员高空跌落。
