Description of the Related Art With the redevelopment of cities, construction work in urban areas has increased, and various heavy machinery such as live excavators and boring machines have been introduced. By the way, these heavy equipments usually generate a considerable amount of construction noise, that is, noise, depending on the model. By the way, the noise generated by the drilling machine used for the chemical injection method in urban areas is
It is said that it is around 120 horns, greatly exceeding the regulation value of 85 horns defined by the Noise Regulation Law.

どの方法によって対応している。Therefore, in order to protect citizens' lives from these noises, that is, to suppress noise pollution, for example, a noise generating part of a heavy machine, a front part which sucks and exhausts high-pressure working air, for example, in the hole drilling machine. Is covered with a large box-shaped soundproofing device, or in the case of a hydraulic hammer, a similar soundproofing device is attached to the front head part, and a soundproofing panel is erected in the work area to temporarily install a soundproofing wall. We are taking measures to prevent the noise from affecting the construction site.

の点からも問題点が指摘されていた。However, when a large soundproofing device is assembled to the noise-producing heavy machine, it is inevitably a factor that reduces the work efficiency of the heavy machine. Further, when the sound insulation wall is temporarily installed with the soundproof panel so as to surround the work area, there is a problem that the temporary installation cost becomes expensive. In particular, panel rent and temporary assembly costs are high, and in any case, existing measures do not provide sufficient soundproofing functions, and if possible, enormous costs are required. Problems were also pointed out in terms of work safety management.

測定値との関係で適宜設定することが好ましい。[Embodiment] In the above-mentioned embodiment, the sound insulation walls made up of simple sound insulation walls were constructed on both the left and right sides of the noise generation source. However, when constructing the sound insulation wall so as to surround the noise generation source depending on the situation of the site. There is also. Further, the height is preferably set as high as possible from the noise generation source, but is preferably set appropriately in relation to the measured value of noise.

できる。Since the present invention is configured as described above, it has the following effects as compared with the conventional method of directly attaching a soundproof device to a heavy machine or the method of constructing a sound insulation wall using an existing sound absorbing panel. Is demonstrated. (1) Since glass wool or rock wool is covered with a sheet as a sound absorbing material to form an extremely simple mat-shaped soundproof wall unit, it has high functionality as a soundproof wall. (2) In addition, a lattice-shaped rope is stretched over the front side sheet and the back side sheet, respectively, and a soundproof wall having an integrated structure of the sound absorbing material and the front and back sheets is formed by connecting the sound absorbing material along the rope with a sewing thread passing through Since it is a unit, it can be easily attached and detached at a predetermined position, and the overall structure does not lose its shape. (3) The soundproof wall or the soundproof wall itself is a temporary facility for a limited period during the so-called construction period, particularly during the use period of heavy machinery that causes noise. In this respect, the method and means according to the present invention are easy to install and remove as described above, and therefore can be easily added, dismantled and removed, or relocated, and the temporary construction cost is lower than that of the conventional soundproof wall panel or the like. In other words, the structure is optimal for temporary equipment. As described above, the present invention can bring about remarkable merits and effects as compared with the conventional means method in terms of functionality as a noise prevention device and also in terms of its provisional cost.
