Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine (TBM) construction technology, and in particular to a soundproof shed for a blower used in TBM construction. Background Technology

[0002] During the construction of the working shaft shield tunnel, blowers are needed to supply air into the tunnel. Due to the long shield tunnel line and small tunnel diameter, the working temperature inside the tunnel is high, and workers are prone to heatstroke. In addition, there are many residential areas nearby, and the noise requirements are high. The blowers are noisy, which causes great disturbance to the lives of nearby residents. Utility Model Content

[0003] This utility model provides a soundproof shed for a blower used in shield tunneling construction, in order to solve the problem of excessive noise from blowers in shield tunneling construction in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is: a soundproof shed for a blower used in tunnel boring machine (TBM) construction, comprising:

[0005] The shed is configured as a soundproof structure, which includes an inner steel plate, sound insulation cotton, and an outer steel plate. The sound insulation cotton is sandwiched between the inner steel plate and the outer steel plate. The inner steel plate has several holes.

[0006] Preferably, the diameter of the hole is 1 cm and the distance between adjacent holes is 1.5 cm.

[0007] Preferably, the thickness of the sound insulation structure is 50cm.

[0008] Preferably, the sound insulation cotton is rock wool.

[0009] Preferably, the inner top of the shed is provided with a heat insulation layer.

[0010] Preferably, one end of the shed is provided with an air inlet, and the other end of the shed opposite the air inlet is provided with a mounting hole for installing the air belt of the blower.

[0011] Preferably, the air inlet is a rectangular hole with a side length of 1m.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: the structure of inner and outer steel plates makes the structure of the shed more stable, and the sound insulation cotton is sandwiched between the inner and outer steel plates. The inner steel plate has several holes. Thus, when the blower is working, some of the noise generated is reflected by the inner steel plate, and some enters the holes, collides with the inner walls of the holes, and is then absorbed by the sound insulation cotton. Finally, it is reflected by the outer steel plate, reducing the sound transmitted to the outside of the shed and effectively reducing the impact of the blower noise on the surrounding environment.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1 to 4As shown in the figure, this application embodiment provides a soundproof shed for a blower 20 used in shield tunneling construction, including a shed body 10, which covers the outside of the blower 20. The blower 20 is connected to a wind belt 70, which is a steel wind belt 70. When the blower 20 is working, it sends air into the tunnel through the steel wind belt 70. The blower 20 used in shield tunneling construction will generate a lot of noise when it is working. The shed body 10 is set as a soundproof structure to block the noise of the blower 20. The soundproof structure includes an inner steel plate 30, a sound insulation cotton 40, and an outer steel plate 50. The structure of the inner steel plate 30 and the outer steel plate 50 can make the structure of the shed body 10 more stable. The sound insulation cotton 40 is sandwiched between the inner steel plate 30 and the outer steel plate 50. The inner steel plate 30 is provided with a number of holes 31. In this way, when the blower 20 is working, part of the noise generated is reflected by the inner steel plate 30, and part enters the hole 31, where it collides with the inner wall of the hole 31 and is then absorbed by the sound insulation cotton 40. Finally, it is reflected by the outer steel plate 50, which reduces the sound transmitted to the outside of the shed 10 and effectively reduces the impact of the noise generated by the blower 20 on the surrounding environment.

[0022] Specifically, taking into account the size of the blower 20, the canopy 10 is designed to be 10m long, 5.2m wide, and 3.9m high. The diameter of the holes 31 on the inner steel plate 30 is 1cm, and the inner steel plate 30 is densely covered with holes 31. The spacing between adjacent holes 31 is 1.5cm. This allows noise to be reflected in multiple places on the inner steel plate 30, effectively reducing noise.

[0023] The combined thickness of the inner steel plate 30, sound insulation cotton 40, and outer steel plate 50 is 50cm. This ensures both overall structural strength and excellent noise reduction.

[0024] The sound insulation cotton 40 in this application is rock wool. Rock wool has advantages such as high compressive and tensile strength, low water absorption and moisture absorption, good dimensional stability, no thermal expansion or contraction, and aging resistance. It is compatible with external wall systems and provides buildings with effective thermal insulation, energy saving, fire protection, and protection against extreme weather conditions.

[0025] A heat insulation layer 60 is installed on the inner top of the canopy 10. The heat insulation layer 60 is a color steel tile heat insulation layer 60. The heat insulation layer 60 is located above the blower 20. As the surface temperature of the exterior of the canopy 10 rises under the sun's radiation, the temperature inside the canopy 10 also rises. The heat insulation layer 60 can partially block the heat radiated from the top of the canopy 10 to the blower 20, effectively reducing the temperature of the blower 20 and ensuring that the airflow entering the tunnel is at a moderate temperature.

[0026] An air inlet 11 is provided at one end of the canopy body 10. The air inlet is a rectangular hole with a side length of 1m. The air inlet 11 connects the outside to the inside of the canopy body 10. An installation hole is provided at the other end of the canopy body 10 opposite to the air inlet 11. The installation hole is used to install the air belt 70 of the blower 20. The size of the installation hole is adapted to the air belt 70 to ensure the stability of the air belt 70.

[0027] An entrance 12 is also provided on the shed 10 to facilitate the entry and exit of staff.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
