Hefei Urban Rail Transit Co., Ltd. released the news on the 5th, the second batch of civil engineering projects on the 2nd line totaling 7 stations and 8 zones will be officially started construction at 24:00 on the evening of the next week.
Following the construction of the Qianshan Road Station, the second batch of civil engineering works for Line 2 to be started will be completed in 7 stations and 8 intervals, from Qianshan Road to Wulidun, from Sanxiaokou to Sipai Building, from Xiaodongmen to Dadongmen and from From East First Ring to Tongling Road, the project is just across the most prosperous central city of Hefei. According to the previous design plan, at least two lanes of two lanes can be secured on the Yangtze River during the construction period, and the densely trafficked Yangtze River Road can guarantee two lanes of six lanes. The construction period of Jinzhai Road Station in Sanxiaokou is the longest, and the total construction period for dismantling flyovers and subway stations is 32 months. In the preliminary design plan, the two-way 6-lane+2 sidewalk in the direction of the Yangtze River Road will be guaranteed, and the Jinzhai Road will remain unchanged. Number of lanes. In the preliminary design, Qingyang Road Station, Xiyuan Road Station, Changfeng South Road Station, Jinzhai Road Station, and Suzhou Road Station are planned to provide protection for two-way 6 lanes +2 slow lanes on Changjiang West Road. Dongyi Ring Road Station guarantees that the Yangtze River East Road be two-way. 4 lanes + 2 lanes, Tongling Road Station guarantees two lanes of 5 lanes and 2 lanes on the east side of the Yangtze River.
If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
