Detailed Product Description: | Bellows was first born in the United Kingdom (1784), 1896, the United States took the lead for corrugated board channel, culvert pipe feasibility study, and for the first time applied to culverts, first corrugated sheet the culvert is applied to Edinburgh, Scotland, UK close neighbor of farmland irrigation in 1913 1923 American Railway Engineering Association corrugated board channel test, in 1929, Canada's first bellows used in a coal mine in the Illinois Central Railroad. 1931 Australian built 8m automotive channel a 1990 Japan highway design specification to develop the design and technical specifications of the bellows. With the installation of the bellows over the world, to prove the versatility of such structures in a variety of use cases, and its life has been exceeded the design life. Liberation and the liberation of the early of applications have corrugated pipe culverts, such as the 1950s, the construction of corrugated pipe culvert applied to the repair works had the the budongquan section of the Qinghai-Tibet Highway, dug to 70 found that the use of good condition. 1965 the Yunnan Highway Administration overhaul of the Burma Road had excavated a piece of steel bellows over water culvert pipe, was confirmed for the period of the Second World War installed (imported from the United States). After the reform and opening up, Shenzhen and Datong Coal Mine are imported finished culvert construction; September 1998 at the Shanghai Pudong Takahashi excavated a period of one meter in diameter over the water corrugated pipe culverts, research for the 1948 installation for the time Military sidewalk. Due to many factors, corrugated pipe culvert is not widely used, to the late 1990s, our country was gradually carry out the application and research of highway steel corrugated pipe culverts, production. From 1997 to 1999 in the permafrost regions of the Qinghai-Tibet Highway paving three corrugated metal pipe culverts, to solve the problems in permafrost areas culverts damaged due to thaw and frost heave. Ching Hong Road (State Road 214) from 2001 to 2002 in Qinghai Province, Ning party Highway (227 State Road) on application of steel corrugated pipe culvert near 200 the Heilongjiang Road application of more than 100 in the the Daxinganling plus Desert Highway (Provincial Highway 207). Shanghai municipal services, such as engineering, have been gradually research Application oval steel bellows as culverts, channels. In order to solve the the Daxinganling permafrost region culvert foundation stability issues, the Highway Bureau of Heilongjiang Province and the headquarters of plus desert highway construction corrugated pipe culvert, to accommodate the deformation and subsidence caused due to permafrost degradation. Built 100 Yu Daobo pattern pipe culverts, without foundation. After one year of use, the Transportation Research Institute of Heilongjiang Province corrugated pipe culverts comprehensive survey due to construction reasons, in addition to a very small part of the basis of improper handling, waterproof improper handling uneven settlement deformation Han physical phenomenon of stagnant water and seepage , most corrugated pipe culvert use state. Has not yet discovered the damage due to structural reasons. |
