Product design and installation of large sound barrier (1) noise barrier design target sound barrier noise refers to the amount of noise sources in a given reception point set in around the same sound barrier measured sound level difference, used to measure the sound barrier on the direct sound abatement effect. After taking into account the combined effect of setting the sound barrier and correction of various factors. Environmental characteristics of the location and the location of the sound barrier length and location of sensitive sites (2) the sound barrier, window orientation, wall height, and linear and other factors. According to the actual terrain, this paragraph set the sound barrier shielding effect of noise on the current basis. Master product quality control a sound barrier installation, excavation: Stake performed by measuring what is ah excavation silencer wall, excavation of soil poured directly outside the prescribed place roadbed. 2, mechanical testing and template preparation: Mix a day before the opening of the mixer, vibrator, generators seizure cases, no-load air operation, cleanup template, apply release agent; template using steel frame support. 3, material inspection: according to the frequency of regulatory requirements for testing the indicators, in line with the requirements of the material can be used, and every day to detect the moisture content of the aggregate of the best silencer wall construction mix adjustment. 4, concrete testing and specimen preparation: for the indicators to test concrete wall silencer, two sets of specimen preparation day silencer wall where the sale of random sampling. 5, on-site management: Cement focus stacking, scheduled according to specifications by laboratory testing, gravel materials were stacked according to specifications, the construction of the strict implementation of norms, always observe the deformation of the template, on the basis of the strength of the walls after more than 5MPa location of construction, attention to sound barrier embedded parts to ensure accurate, the top surface of the base elevation strictly controlled. 6. Health: Health watering, keep the surface wet concrete, and health of not less than seven days. 7, Chaimo: pouring 72 hours after form removal, pay attention to the protection of the concrete form removal, the size of each part Chaimo after checking components, whether cellular, Pock, does not meet the requirements of the waste. 8, the product master sound barrier installation: to ensure that the vertical column, fixed bolt, coupled with the underlying seams Screen dense.
