Abstract: The occupation of the present inventor is an excavator operator and most of the jobs are excavation and burial of pipes. The working areas are generally located in Taipei City and New Taipei City, which are densely populated areas. Recently, due to improved quality of life and the requirement for driving safety of road users, the governmental agency that pays attention to road levelness strictly requires the construction units, such as power company, telecommunication, tap water, gas, and sanitary sewer system, to cut the road in a neat and regular manner in order to prevent the road surface from cracking when these construction units attempt to carry out constructions of excavation and burial of pipes. The conventional way of excavation and pipe burial construction operation must be carried in such a way that an excavator must be used to break the road surface and dig out soils and then pipes can be buried, and this suffers the following shortcomings. The first shortcoming is that cutting road surface is carried out by manually operating the excavator so that the progress of cutting is slow and may be affected by the terrain to generate noise that may exceed 100 decibels, not only environmentally unfriendly but also disturbing the residents. The second shortcoming is that breaking the road surface is carried out with a pulverization device attached to an excavator or a shovel loader so that the progress of breaking is slow, the working hours are extended, noise generated may get as high as one hundred decibels, the asphalt blocks so generated cannot be recycled and reused, making it a waste of resources, and the construction expense may get raised. The third shortcoming is that construction carried out in the daytime may often protested by the residents and may be fined by the environmental protection agency, not to mention working in the nighttime. The traditional way of construction means high nose plus being not environmentally friendly plus increase of working hours plus waste of resources. Due to upgrade of national environmental consciousness as well as continuously increased cost and shortage of material worldwide, the inventor believes the traditional way of construction is not very friendly to the environment and wastes materials. The inventor has been inspired by the operation of excavation and burial of pipes to develop a device specifically for cutting, shoveling, and pulverizing hard road surface with low-noise, which is temporarily referred to as a low-noise pipe trench cutting tool as an accessory of an excavator and a low-noise pipe trench cutting tool as an accessory of a shovel loader. Construction carried out with such a device can be much faster and quieter than the traditional ways so as to shorten the working hour and allow for recycling of the material to practice environmental protection. The difference between the prior art and the novel operation process (carried out with the low-noise pipe trench cutting tool as an accessory of an excavator and the low-noise pipe trench cutting tool as an accessory of a shovel loader) is as follows. The first feature is that there is no need for manually cutting the road surface so that two construction steps of the road surface breaking process can be saved, which generally causes unbearable noise and extends the working hour. If the low-noise pipe trench tool is used, only one operation process is needed to get the job done with low-noise and the working hour can be greatly shortened. The second feature is that for an asphalt paved road, which is generally referred to as a flexible road, using a traditional pulverization device to break the road is time consuming and not environmentally friendly. The broken asphalt blocks and the soil are discarded together, leading to an increase of construction expense. If the low-noise pipe trench cutting tool is used, besides working hour being shortened, the shoveled and broken asphalt residues can be collected and sold to thereby reduce the construction cost and practice environmental protection, thus effectively re-using resources. The third feature is that the low-noise pipe trench cutting tool as an accessory of an excavator and the low-noise pipe trench cutting tool as an accessory of a shovel loader are put into a low-noise operation so that the noise generated during the construction can be minimized, thereby increasing construction efficiency and also practicing environmental protection with resources being re-usable. This is a novel and revolutionary way of construction, having multiple advantages and a promising future.
