Foundation pit safety fence for bridge engineering construction site

Abstract

The invention relates to the technical field of foundation pit fences, in particular to a foundation pit safety fence for a bridge engineering construction site. A fence rod is movably embedded and connected in a base, a fence frame is movably connected to the outer surface of the fence rod, a wind direction rod is movably connected in the fence rod, and a wind direction wheel is fixedly connected to the top end of the wind direction rod. Threaded rods are fixedly connected to the bottom end of the wind direction rod and extends into the base, toothed plates are engaged to the two sides of the outer surface of the threaded rods, first connecting rods are movably connected to the outer surfaces of the toothed plates, second connecting rods are movably connected to the bottom ends of the first connecting rods, and pressing rods are movably connected to the bottom ends of the second connecting rods. Reinforcing plates are fixedly connected to the bottom ends of the pressing rods, the first connecting rods and the second connecting rods drive the pressing rods to downwards push the reinforcing plates to be attached to the ground, then the contact area between the base and the ground is increased, the effect of resisting wind blowing is achieved, and the fence is prevented from being blown down by strong wind.

Description

technical field [0001] The invention relates to the technical field of foundation pit fences, in particular to a foundation pit safety fence for a bridge engineering construction site. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size, while the bridge engineering foundation pit is mainly used for the construction of caps, abutments and expanded foundations. When workers work in the foundation pit, they usually need to A fence is set on the ground at the outer edge of the pit to serve as a reminder for construction. [0003] During the construction of the foundation pit, the site is relatively open, and there is no obstacle when the wind blows. Usually, the wind near the foundation pit is relatively strong, and the fence is easily toppled when it is blown by the wind, and the soil around the foundation pit is loose, so it is difficult to reinforce the fence. ...

Problems solved by technology

[0003] During the construction of the foundation pit, the site is relatively open, and there is no obstacle when the wind blows. Usually, the wind near the foundation pit is relatively strong, and the fence is easily toppled when it is blown by the wind, and the soil around the foundation pit is loose, so it is difficult to reinforce the fence. After the dust is raised, it floats in the air, and the dust floating in the air cannot be settled, which affects the health of workers and the progress of construction. Therefore, those skilled in the art provide a safety fence for foundation pits for bridge engineering construction sites to solve the problem. Problems raised in the background art above
