Pedestrian, vehicle accidents have occurred, the people's life and property safety is a great threat, but also to the relevant competent authority responsible for a huge security pressures. According to reports, covers facilities and uneven pavement or gap too wide will cause abnormal noise, jumping phenomenon. City Management Committee cityscape November 27 last year at once informed, commissioned by the municipal gardens testing center on the West Pearl River and covers infrastructure construction quality Shamian Street were forced sampling display, noise means the overall pass rate was 1.9 percent, which the West Pearl River 9 covers road noise abatement device checks pass rate of 0%. In an interview with the detection, Zhujiang Road West covers the use of time is not yet two years. This specification covers the requirements of the new uses with anti-ring seals, adjustable anti-settlement structure, elastic self-locking structure, resolve abnormal sound fundamentally, sedimentation, noise and uneven problems. Municipal Construction Committee, said the new covers additional new anti-ring seals as in the past will no longer be using the stick-on tape, but instead covers the edge of the wedge added, not easy to wear off. Elastic self-locking structure can be further compacted strip. These measures can guarantee covers the new anti-noise performance greatly enhanced. New roads in future tenders will be included costs of new road construction noise abatement device costs, should be clearly reflected in the design stage. Anti-dropping network covers - manhole Fence Products Requirements 1. Fence diameter 600 mm, bearing not less than 300 kg; 2. net body, while high-strength polyethylene rope and other types of corrosion-resistant material tide; 3. net mesh body rope diameter 6 mm, 4 wells with high strength wire mesh, expanded yarn, polyester, polyvinyl alcohol, and other materials as raw material. 5. All net rope by not less than three shares into a single rope. 6. covers all nodes in the Internet should be fixed. 7. diamond or square shape; the mesh side length should not exceed 10cm. 8.48cm 50CM × 4 edges. 9. net rope breaking strength ≥1600N. 10. ≥500 joules of impact shock, net rope does not break, the test weight should not touch the ground; for various caliber Hebei Five Star Electric Equipment Co., Ltd. of municipal wells, electricity well, communication wells, water wells, checking wells, gas wells and other subterranean wells covers safety net covers protective covers anti-dropping network safety net, product appearance, tension, impact, corrosion and other technical indicators by the provincial, national quality inspection departments to monitor certification. Hebei Five Star Electric Equipment Co., municipal wells fall protection safety net net, power anti-dropping network safety net wells, fall protection safety net wells communication networks, water wells fall protection safety net net, check anti-dropping network safety net wells, gas wells Protection net anti-dropping network water wells fall protection safety net is made of high-strength wire mesh, other materials such as polyester / PVA / nylon and other to be customized, the technical indicators are in line with Q / 1621HJG001-2012 standard product design aesthetics, ease of use, in line with the principles of mechanics, with standard quality, through the national quality inspection departments for the record and detection. The country has a large number of municipal Inoue put into use.
