Embodiment 1

[0043] Such as figure 1 with figure 2 As shown, a road green dust reduction and environmental protection construction structure includes a drill bit 4, a dust suction device, and a first support plate 1 with a through hole in which the drill bit 4 can be inserted freely. The first support plate 1 serves as a supporting platform. An intake pipe 7 with the same inner diameter and through hole is provided on the side. One end of the intake pipe 7 is connected to the through hole of the first support plate 1, and the other end of the intake pipe 7 is connected with a buffer pipe 701. The buffer pipe 701 can be a hose or a buffer pipe. The other end of 701 is connected with an elastic edge 703, and the outside of the intake pipe 7 is sleeved with a push ring 702, which is used to push the elastic edge 703, and the dust suction device is connected with the inner space of the intake pipe 7. In this embodiment, the power The device drives the push ring 702 to move laterally. The push r...

Embodiment 2

[0046] Same as Example 1, the difference is: image 3 with Figure 5 As shown, a second support plate 2, a sieve tube 5 and a collecting device 3 are also provided. The second support plate 2 is arranged in parallel with the first support plate 1. As a supporting platform, one end of the sieve tube 5 is connected to the first support plate 1. Rotational connection, the other end passes through the second support plate 2 and is meshed and connected with gears installed on the second support plate 2 through teeth arranged on the outside; the inside of the collecting device 3 is a hollow structure, and the screen cylinder 5 is located in the aggregate Inside the device 3, along the direction from the first support plate 1 to the second support plate 2, the side of the screen cylinder 5 is provided with a first screen hole and a second screen hole in sequence, the size of the second screen hole is larger than the first screen hole The inside of the screen cylinder 5 is provided with...

Embodiment 3

[0051] A construction method for a road green dust reduction and environmental protection construction structure adopts the road green dust reduction and environmental protection construction structure in Embodiment 2. The following is a specific construction description of the deep foundation pit supporting structure at the junction of bridges and tunnels.

[0052] A construction method of a highway green dust reduction and environmental protection construction structure, and its steps are:

[0053] a. Now work on a rock with uneven sides. The push ring 702 pushes the elastic edge 703 into close contact with the side of the rock. The ratio of the non-contact area of ​​the elastic edge 703 to the rock is less than 15%;

[0054] b. The drill bit 4 performs drilling operations on the rock. The dust suction device sucks the dust generated during the drilling into the intake pipe 7 and enters the screen tube 5, the screen tube 5 rotates, and the push screw 502 pushes the dust to the secon...

Abstract

The invention, which belongs to the technical field of road engineering, discloses a green dust-reducing environment-friendly construction structure for a road and a construction method thereof. The green dust-reducing environment-friendly construction structure comprises a drill bit and a first support plate having a through hole, wherein the drill bit can be inserted into the through hole freely. An inlet air pipe having the same inner diameter as the through hole is arranged at one side of the first support plate; one end of the inlet air pipe is connected to the through hole of the first support plate and the other end of the inlet air pipe is connected with a buffer pipe; and the other end of the buffer pipe is connected with an elastic edge. A push ring sleeves the outer side of theinlet air pipe and is used for pushing the elastic edge. In addition, the green dust-reducing environment-friendly construction structure also includes a dust exhaust apparatus communicated with the internal space of the inlet air pipe. Therefore, entrance of dust caused by static blasting hole drilling in the air is avoided. The green dust-reducing environment-friendly construction structure alsohas advantages of low manufacturing cost, high filtering precision and high reliability.

Description

Technical field [0001] The invention belongs to the technical field of road engineering, and specifically relates to a road green dust reduction and environmental protection construction structure and a construction method thereof. Background technique [0002] In the process of building construction, it is usually necessary to remove the rocks in the construction area. At present, most of the rocks are removed by static blasting. Static rock blasting is to drill holes in the blasting rock mass, and pour the prepared liquid static blasting agent into the holes. The static blasting agent will produce expansion pressure after hydration, which is greater than the tensile strength of the rock. Will be burst, so as to achieve the purpose of breaking the rock. For static blast hole drilling, simple manual hand-held drilling rigs are generally used. Larger dust will be generated when drilling on site, which will have a greater impact on the physical and mental health of the operators a...
