Description

Technical Field

[0001] The present invention relates to the technical field of tunnel sound insulation barriers, and in particular to a fully enclosed assembled sound insulation barrier for tunnel engineering and an installation method thereof. Background Art

[0002] Tunnel engineering is an inevitable part of modern urban construction. It plays an important role in transportation, water supply, gas supply and other fields. However, the noise and vibration generated by the tunnel after it is opened to traffic often cause discomfort to the surrounding residents. Usually, a barrier for sound insulation is installed in the tunnel. However, the current tunnel sound insulation barrier is usually an integrated structure, which is non-detachable and has a low degree of modularization, which makes transportation difficult and increases a lot of transportation costs. In addition, since the top of the tunnel is curved, the existing sound insulation barrier has a consistent curvature and cannot fit tightly to the top of the tunnel, which makes installation difficult. Therefore, in order to solve the above problems, a fully enclosed assembled sound insulation barrier and an installation method for a tunnel project are provided. Summary of the invention

[0003] In view of the deficiencies in existing tunnel noise barrier technology, the purpose of the present invention is to provide a fully enclosed assembled noise barrier and installation method for tunnel engineering, which has the advantages of high modularity and easy installation.

[0004] To achieve the above-mentioned purpose, a technical solution adopted by the present invention is: a fully enclosed assembled sound insulation barrier for tunnel engineering, comprising a sound insulation layer, a shaping base layer, a shaping steel rope, a limit buckle and a positioning nail, wherein a sound insulation layer is provided on one side of the shaping base layer, and a plurality of V-shaped grooves are provided on the end surface of the other side of the shaping base layer, wherein the V-shaped grooves divide the shaping base layer into a plurality of trapezoidal blocks, wherein the shaping steel rope is arranged in the shaping base layer, wherein the middle part of the shaping steel rope is fixed to the middle part of the shaping base layer, and the two ends of the shaping steel rope slide axially in the shaping base layer, wherein the shaping steel rope is used to connect a plurality of trapezoidal blocks, and the end surfaces of the plurality of trapezoidal blocks are all provided with limit buckles for fixing the shaping steel rope, wherein the positioning nail is arranged at the center of the end surface of the shaping base layer and passes through the sound insulation layer, wherein a recessed positioning hole is provided on one side of the shaping base layer, and a protruding positioning pin is provided on the other side of the shaping base layer;

[0005] Preferably, the outer edge of the positioning pin also has a limiting ring protruding from the positioning pin body;

[0006] Preferably, the sound insulation layer is made of a tough material;

[0007] Preferably, the inner wall of the positioning hole further has a concave annular groove, and the annular groove is used to engage with the limiting ring on the outer edge of the positioning pin;

[0008] Preferably, the middle part of the limit buckle has a through hole for inserting the shaping steel rope, the end of the limit buckle extending out of the shaping base layer has a flange head, and the end of the limit buckle extending into the shaping base layer has an embedded pin;

[0009] Preferably, the trapezoidal block in the shaping base layer has an embedding groove corresponding to the insertion position of the limit buckle, the embedding groove is used to embed the embedding pin, and the embedding groove is used to fix the limit buckle in the shaping base layer to fix the shaping steel rope;

[0010] A method for installing a fully enclosed assembled noise barrier for a tunnel project comprises the following steps:

[0011] S1. Installation location positioning: First, the noise barrier is clamped by the installation fixture, and then the noise barrier is moved to the installation location by the robotic arm;

[0012] S2. Noise barrier splicing: The noise barriers are moved closer to each other by operating the robotic arm, so that the positioning pin on one side of the noise barrier is inserted into the positioning hole on the other side of the noise barrier. At this time, the annular groove in the positioning hole is engaged with the limiting ring on the outer edge of the positioning pin, thereby completing the splicing of the noise barriers;

[0013] S3. Fixing the noise barrier to the wall: The mechanical arm drives the clamp to nail the noise barrier into the wall, so that the positioning nails set at the center of the end surface of the fixed base are nailed into the wall to fix it, so that the noise barrier can fit the wall tightly;

[0014] S4. Shaping of the noise barrier: After the noise barrier is fixed on the wall, since the sound insulation layer is made of a tough material, the V-shaped groove on the end face of the shaping base layer divides the shaping base layer into multiple trapezoidal blocks, so that the noise barrier can fit the tunnel top more closely by squeezing the V-shaped groove. At this time, the pneumatic component on the control fixture is used to push the limit buckle into the shaping base layer, so that the shaping steel rope is relatively fixed to the multiple trapezoidal blocks, and ensure that the V-shaped groove will not rebound after being squeezed;

[0015] The beneficial effects of the present invention are: 1. By inserting the positioning pin on one side of the sound barrier into the positioning hole on one side of the other sound barrier, the annular groove in the positioning hole is engaged with the limiting ring on the outer edge of the positioning pin, thereby realizing the splicing between the sound barriers; 2. A plurality of V-shaped grooves are provided on the end face of the shaping base layer, and the plurality of V-shaped grooves divide the shaping base layer into a plurality of trapezoidal blocks, so that when the sound barrier is attached to the top of the tunnel, it can be squeezed by the V-shaped groove to obtain an effect of better fitting the inner wall of the tunnel.
