Guarding the good color of Damei Qinling

Reporter Zhao Yuanqing

On July 19, the continuous rainfall made the depths of Qinling look more green. On the upper reaches of the Nanqin River, the Tenth High -speed Railway Project of China Railway Twenty Innings is a busy scene: the high bridge pier with a 37 -meter bridge of the South Qinhe Bridge is being poured nervously; the right side of the river, the No. 1 concrete mixing station covering nearly 50 acres is stepping up The concrete is produced; on the construction road on the left side of the river, the transport vehicle loaded with the dregs is waiting for the high -pressure rinse before the appearance ...

You can produce 1500 cubic meters of concrete No. 1 mixing daily. It is the largest mixing station in the West Ten High Speed ​​Railway. In the intelligent monitoring room, the No. 1 mixing station was staring at the screen and viewed the real -time construction screen of the mixing stations: "All raw materials need to be cleaned before entering the position. During the use of sand and gravel Over the alarm line, the spraying equipment in the material warehouse will automatically start the sprinkler dust reduction mode. "

West Ten High Speed ​​Rail No. 1

There are many discharge of wastewater discharge of sand and gravel transportation of dust, large production of ingredients, and large discharge of wastewater generated by construction, which will all become the "culprit" of destroying the ecological environment. To this end, the project department resolutely curbs all pollution sources of concrete processing production through the establishment of a closed -type warehouse, installing door -type vehicle rinse equipment, increasing sewage treatment equipment, and using an intelligent monitoring system.

"Our construction tube section is all located in the hinterland of Qinling. It is an important ecological barrier in the country. The ecological environment must not be destroyed. When we come, it is green mountains and green mountains. When the construction of the Western Tenth high -speed rail is completed, it must still be mountains and rivers." It is understood that it is understood that In order to protect the ecological environment of the Qinling Mountains from being damaged by construction, the project builders communicated extensively with the Iron 1 Courtyard of the design unit in the early days of entering, allowing environmental protection facilities and main projects to be designed, constructed, and put into use at the same time.

When the concrete tank is cleaned, a large number of wastewater discharge containing chemical additives has always been a problem that plagues the construction unit. In order to solve this problem, the project builders and owners' units and design units actively communicate to purchase mud water separation integrated equipment and water treatment equipment for mixing stations. After separation of wastewater containing sand and gravel, the solid part is compressed into mud cakes, and the sedimentary filter water is accumulated and used after accumulation. Not only do the construction wastewater have a good place, the living wastewater of nearly a thousand construction workers in more than 10 living areas can also be treated by these equipment.

With a sound of "Boom Ronaldon", the burst construction of the No. 1 Xiaoling Tunnel ended successfully. Sprinkling equipment spray dust reduction, ventilation pipes to start air replacement, fog gun machines to reduce dust and remove ash ... In just a few minutes, the turbid tunnel immediately became fresh. In the winding mountain forest, the transport vehicle covered with dust -proof cloths lined up neatly to transport residue stones. There were technicians in front of the technicians to guide traffic in advance. The mud dregs fell beside the road.

The reinforced processing site is fully closed, temporary land acquisition collection collection of cultivated land for land, abandoned soil field drone joint intelligent monitoring system without dead angle control, regular picking of domestic garbage, daily environmental self -inspection, and regular inspections of environmental protection commissioners ... … In order to protect the Qinling ecology, the Tenth High -speed Railway Project Department of the 20th Bureau of China Railway has ensured that the construction environment is not affected through a series of rigorous control measures, allowing Qinling green mountains and green waters to remain unchanged, and the ecological environment is not polluted.
