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 guard with a good warning effect. The construction site foundation pit protective guard comprises a frame body, a plurality of handrails are welded into the frame body, strip-type grooves are formed in the side walls of the handrails, and two springs are fixedly connected to the inner bottoms of the strip-type grooves. Glass sleeves and rubber sleeves are fixedly connected to the inner tops of the strip-type grooves, iron sliding blocks are slidably connected into the glass sleeves and the rubber sleeves, the outer walls ofthe glass sleeves and the outer walls of the rubber sleeves are slidably connected with magnetic scraping rings, wherein chemical fiber layers are arranged on the side walls of magnetic sliding blockswhich are located in the glass sleeves, and fur layers are arranged on the side walls of magnetic sliding blocks which are located in the rubber sleeves. According to the construction site foundationpit protective guard with the good warning effect, through point discharge of two mutually matched conductive needles, neon in a square cavity is electrified to emit striking red light, so that the good warning effect is provided during night construction, and the danger due to the fact that vehicles collide the protective handrails to intrude into a construction site during night travelling is avoided.

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...
