When it comes to sound insulation barrier projects, people will think of the sound insulation barrier panels installed on both sides of the viaduct, around the residential area, and next to the railway. The main function of the sound insulation barrier is to reduce noise pollution and improve the comfort of the people living near the sound source. the

The sound insulation barrier is assembled from a plurality of steel column frames with "work"-shaped grooves and multiple sound-absorbing and insulating unit panels, and sound-absorbing and insulating panels are installed in the "work"-shaped grooves of two adjacent steel column frames. cell board. It is characterized in that the sound-absorbing and insulating unit board is fixed by the limit piece set in the "work" shaped groove (the limit piece includes: a fixed part, a support part and a limit part), the fixed part and the support part form an angle steel structure, and the fixed part The part is parallel to and attached to the bottom end face of the "I" shaped groove, and is fixed on the bottom end face of the "I" shaped groove. The supporting part is parallel to the side end surface of the "I" shaped groove, and is used to support the sound-absorbing and insulating unit board. The limiting part is fixed on the supporting part, forms a limiting groove with the supporting part and a side end surface of the "I" shaped groove, and the sound-absorbing and insulating unit board is fixed in the limiting groove. the

In addition, the workers who install the sound-absorbing screen body handle it with care. It is not allowed to drop it or use a forklift to load it. During transportation, the screen body must avoid extrusion, and some accessories need to be packed in sacks for prevention. When the vehicle is transported, the columns, sound-absorbing screens, sound-insulating screens and support strips are wrapped with hemp wadding, and the reflective screens are fixed with fixing frames. the

Seasonal issues should be considered during the installation process. Heating devices should be used to pour mortar in low temperature conditions, and cooling devices should be used in high temperature conditions. If the wind is strong during the installation process, wind protection measures should be taken to ensure that the columns and partitions are horizontal and vertical meet the requirements. The installation and construction personnel should accept unified command at the site, do a good job of safety precautions, and do a good job in construction cooperation; during the transportation and handling of various materials, they should pay attention to the protection of materials to avoid damage to related coatings and affect their waterproof and anti-corrosion functions.
