The picture shows that August is the most beautiful season in Hulunbuir Grassland in the wet section
of the second card of Haiman Expressway. In Erka Wetland Nature Reserve, Manzhouli City, Hulunbuir, Inner Mongolia Autonomous Region, reeds are rippling and gulls are flying. At the construction site of Erka Wetland Bridge on Haiman Expressway, machinery came and went, and workers worked in an orderly manner. The green protective net on the bridge is integrated with the surrounding green grass and green water. The 4.8-kilometer-long Erka Wetland Bridge on Haim
an Expressway is one of the "bridges instead of roads" on Haiman Expressway, and also an "environmental protection bridge" with two functions of sightseeing and ecological protection. It is understood that the original approved feasibility study report of Haiman Expressway Project is mainly roadbed crossing Erka Wetland. In order to strengthen the comprehensive ecological management of Hulun Lake, after research and demonstration, the wet section of the second card of Haiman Expressway has been adjusted to the bridge-based construction scheme, with a total length of 13.9 kilometers, four new bridges and an additional investment of about 1.015 billion yuan.
"The adjustment of Erka Wetland's" road to bridge "scheme is a concrete manifestation of Inner Mongolia's highway construction adhering to ecological priority, green development and promoting the construction of ecological civilization, which is of great significance to the protection of Erka Wetland ecosystem, the promotion of wetland ecological environment restoration and the protection of wetland ecological security." Liu Min, head of the integration and reorganization leading group of Hulunbeir Branch of Inner Mongolia Communications Group, said.
In order to avoid damage to the ecological environment to the greatest extent, during the construction of the project, the headquarters will recycle the waste water produced by the bridge project after sedimentation treatment; set up a temporary anti-seepage storage yard to clean up the mud produced by drilling in time; strengthen the control of construction waste water along the line, and arrange special personnel to clean up the waste produced during concrete pouring. The "special passage"
for animals is also a special scenery on the Haiman Expressway. There are dozens of wild animals such as Mongolian gazelle, roe deer and otter in the project area. The builders have collected a large number of observation data to understand in detail the community distribution, breeding and foraging habits and migration routes of wild animals along the line. An animal passage across the main line and a vehicular overpass for people and animals have been set up in the suitable section of the road, which is convenient for wild animals to drink water, forage and migrate. It also reduces the adverse effects of highway construction on wildlife and animal husbandry production. The main line
of Haiman Expressway Project starts from Hailar North Interchange and ends at Manzhouli Highway Port. Except for the "Road to Bridge" section of Erka Wetland, the rest of the main line has been completed in 2021. Zhao Zhihai, technical director of Haiman Project Construction Management Branch of Inner Mongolia Communications Group, said that up to now, the main deck pavement of four new bridges has been completed and pavement construction is under way, and it is expected to pass the acceptance by the end of November.
Project Name Card
Hai (Laer) Man (Zhouli) Expressway is the last section of Suiman Expressway in Inner Mongolia, with a total length of 188.6 kilometers, which is a national key highway project. It is also an important infrastructure for Inner Mongolia Autonomous Region to implement major national strategies such as the development of the western region and to build a bridgehead open to the north. Among them, the project of "road to bridge" in Erka wetland is of great significance to the protection of wetland ecosystem.
