[0031] Embodiment 1:

[0032] See Figures 1 to 3 , a sound insulation device for tunnel blasting, the sound insulation device for tunnel blasting includes:

[0033] A double-row track 1 horizontally installed in the tunnel. The double-row track 1 divides the cross-section of the tunnel into an upper installation area and a lower installation area. A first sound insulation cotton curtain 2 is fixedly installed in the upper installation area, and several second sound insulation cotton curtains 3 are slidably installed in the lower installation area.

[0034] Specifically, the double-row track 1 is composed of two tracks arranged side by side on a horizontal plane (as shown in Figure 2 ), and its two ends can be fixed to the inner side wall of the tunnel for installation. The upper end of the double-row track 1 can also be connected to the tunnel top through reserved embedded steel bars for installation (as shown in Embodiment 3). The upper end of the first sound insulation cotton curtain 2 is fixedly connected to the arc top of the tunnel. The size of the first sound insulation cotton curtain 2 is adapted to the upper installation area to achieve full coverage of the upper installation area. Several second sound insulation cotton curtains 3 together form a large-size sound insulation cotton curtain that matches the lower installation area to achieve full coverage of the lower installation area. After blasting is completed, in order to facilitate opening the sound insulation curtain in the lower installation area, the second sound insulation cotton curtain 3 is slidably installed in the lower installation area, as shown in Figure 3 , which is a schematic diagram of the second sound insulation cotton curtain 3 in the open state.

[0035] In this embodiment, the tunnel is blocked and covered by the first sound insulation cotton curtain 2 in the upper installation area and several second sound insulation cotton curtains 3 in the lower installation area, so as to absorb, reflect and weaken the sound wave energy generated during tunnel blasting, thus effectively preventing the noise in the tunnel from spreading to the surrounding residential areas and affecting the living and production of the surrounding residents, and further reducing the risk of hearing damage.

[0036] It should be noted that this device is placed at the tunnel entrance and 100 m inside the tunnel. The arrow in the figure indicates the moving direction of the second sound insulation cotton curtain 3.

[0037] [[ID=३०]]Embodiment 2:

[0038] See Figures 1 to 3, based on Embodiment 1, optionally, the upper end of the second sound insulation cotton curtain 3 is slidably mounted on the double-row track 1 through a first hook.

[0039] Specifically, the fixed end of the first hook is fixedly connected to the upper end of the second sound insulation cotton curtain 3, and the hook of the first hook is in sliding contact with the double-row track 1, thereby realizing the sliding installation of the second sound insulation cotton curtain 3. In this way, several second sound insulation cotton curtains 3 can slide along the double-row track 1, so as to realize position adjustment.

[0040] It should be noted that the structure of the first hook is prior art and is not shown in the drawings.

[0041] Optionally, there are eight second sound insulation cotton curtains 3, and the eight second sound insulation cotton curtains 3 are installed staggeredly.

[0042] Specifically, the eight second sound insulation cotton curtains 3 just cover the lower installation area. Since the second sound insulation cotton curtain 3 cannot be unfolded or closed like a curtain, the track is set in the form of a double-row track, and the second sound insulation cotton curtains 3 are installed staggeredly on the double-row track 1. In this way, by moving the second sound insulation cotton curtain 3 to both sides of the tunnel, the opening or closing of the lower installation area can be realized.

[0043] Embodiment 3:

[0044] See Figures 1 to 3 , based on the above embodiments, optionally, three connecting rods 4 are equidistantly arranged in the upper installation area.

[0045] Specifically, the top of the connecting rod 4 is connected to the top of the tunnel, and the bottom is welded to the double-row track 1, so as to realize the support of the double-row track 1; in order to further strengthen the fixation of the first sound insulation cotton curtain 2, the contact part between the connecting rod 4 and the first sound insulation cotton curtain 2 can be tied with iron wire.

[0046] Embodiment 4:

[0047] See Figures 1 to 3 , based on the above embodiments, optionally, a wind belt reserved hole 5 is opened on one side of the first sound insulation cotton curtain 2 close to the inner side wall of the tunnel.

[0048] Specifically, by setting the wind belt reserved hole 5, space is left for the installation of the wind belt to facilitate ventilation in the tunnel.

[0049] Optionally, a second hook 6 is provided below the double-row track 1. One end of the second hook 6 is fixed to the inner side wall of the tunnel, and the other end is used to hook the second sound insulation cotton curtain 3.

[0050] Specifically, after blasting, the second sound insulation cotton curtain 3 is pulled to both sides through the guiding device, and the second sound insulation cotton curtain 3 is hooked by the second hook 6 to fix the position of the second sound insulation cotton curtain 3, so as to leave space.

[0051] It should be noted that the guiding device has nothing to do with the technical problems solved by this device and is prior art, so it will not be elaborated here.

[0052] Optionally, the width of the second sound insulation cotton curtain 3 is 1200 mm.

[0053] Specifically, the width selection of the second sound insulation cotton curtain 3 depends on factors such as the size of the installation space, the required sound insulation effect, and the budget. In this embodiment, a width of 1200 mm for the second sound insulation cotton curtain 3 can meet the requirements.

[0054] Optionally, both the first sound insulation cotton curtain 2 and the second sound insulation cotton curtain 3 are made of fireproof and thickened sound insulation cotton curtains.

[0055] Specifically, through the thickening design, the fireproof and sound insulation effects of the fireproof sound insulation cotton curtain have been further improved. The thickened curtain can better isolate the transmission of heat and sound, providing more lasting protection. The fireproof and thickened sound insulation cotton curtain has good durability and anti-aging performance, and can maintain its fireproof and sound insulation effects for a long time. It is not easily damaged or deformed and can adapt to various harsh environmental conditions.

[0056] It should be noted that the structures and / or installation methods not elaborated in this application can be known to those skilled in the art by combining common general knowledge and / or prior art, and are not the key points of disclosure in this application, so they will not be further elaborated here.

[0057] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and not to limit them. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and details without departing from the scope defined by the claims of this application; the dimensions of the drawings have nothing to do with the specific physical objects, and the physical object dimensions can be changed arbitrarily.
