Problems solved by technology

However, when the street lights fail at night or the light is dark, the driver is unable to see the road clearly and easily crashes into the guardrail and breaks into the construction site. It will absorb part of the light energy, so the reflected light is relatively weak, and the warning effect is average. At the same time, during the construction process on the construction site, dust is flying, and there is a lot of dust near the fence, so dust accumulation on the fence is easy to cause the reflective logo to be blocked, further weakening In order to achieve the warning effect, based on the above-mentioned defects, this application document proposes a

Embodiment 1

[0020] refer to Figure 1-2 , a construction site foundation pit protective fence with good warning effect, comprising a frame body 1, a plurality of railings 2 welded inside the frame body 1, bar-shaped grooves 3 are opened on the side walls of the railings 2, and the inner bottoms of the bar-shaped grooves 3 are fixedly connected There are two springs 4, and the inner top of the strip groove 3 is fixedly connected with a glass sleeve 6 and a rubber sleeve 7. When the spring 4 is manufactured, the natural frequency of the spring 4 needs to be set to be the same as the natural frequency of the construction machinery such as excavators, bulldozers and other equipment engines for foundation pit construction on the construction site.

[0021] Both the glass sleeve 6 and the rubber sleeve 7 are slidably connected with an iron slider 11, and the outer walls of the glass sleeve 6 and the rubber sleeve 7 are slidably connected with a magnetic wiper ring 12, wherein the magnetic scrap...

Embodiment 2

[0027] refer to Figure 3-4 , different from Embodiment 1, the side wall of the railing 2 is provided with a plurality of spray holes 16, and the inner wall of the strip groove 3 is fixedly connected with a plurality of telescopic airbags 15, and the air outlet end of the telescopic airbag 15 faces the nozzle holes 16, A pressure relief valve is installed in the air outlet of the telescopic airbag 15, and the plurality of telescopic airbags 15 are connected to each other. The side wall of the railing 2 is provided with two air inlets 17 respectively connected with the glass sleeve 6 and the rubber sleeve 7. Both ends of the airbag 15 are respectively provided with an air guide tube 20 communicating with the glass sleeve 6 and the rubber sleeve 7 , a first one-way valve is installed in the air inlet 17 , and a second one-way valve is installed in the air guide tube 20 . The first one-way valve only allows air to flow into the glass sleeve 6 or the rubber sleeve 7 from the air i...

Abstract

The invention discloses a construction site foundation pit protective fence with good warning effect, which comprises a frame body, and a plurality of railings are welded inside the frame body; The bottom is fixedly connected with two springs, and the inner top of the strip groove is fixedly connected with a glass sleeve and a rubber sleeve. Both the glass sleeve and the rubber sleeve are slidably connected with iron sliders. The glass The outer walls of the sleeve and the rubber sleeve are slidably connected with a magnetic wiper ring, wherein the side wall of the magnetic slider located in the glass sleeve is provided with a chemical fiber layer, and the side wall of the magnetic slider located in the rubber sleeve is provided with a fur layer . The present invention discharges through two matching conductive needle tips, and makes the neon gas in the square cavity energized to emit eye-catching red light, so that a good warning effect can be provided during night construction, and vehicles can be prevented from colliding with the protective fence when driving at night Breaking into the construction site can lead to dangerous situations.

Description

technical field [0001] The invention relates to the technical field of equipment related to building construction, in particular to a construction site foundation pit protection fence with good warning effect. Background technique [0002] In the initial stage of construction on the construction site, foundation pits need to be dug to pour a solid foundation to ensure that the high-rise buildings will not fall down. [0003] Guardrails are often built around the foundation pit of the construction site to prevent passing vehicles and pedestrians from entering the construction site by mistake and causing dangerous situations. However, when the street lights fail at night or the light is dark, the driver is unable to see the road clearly and easily crashes into the guardrail and breaks into the construction site. It will absorb part of the light energy, so the reflected light is relatively weak, and the warning effect is average. At the same time, during the construction proce...
