The door in the martial arts station in Hangzhou Metro Line 2 and Ning Bridge Station in the second half started
2 Xian Qingchun square in the subway station will be located in the track base
To start the second half of the year in the station in Wulin gate station and Ning Bridge
In the morning in May 16th, Hangzhou City Hall leading line of Hangzhou subway northwest Duan Qingchun Square Station on line 2, Qingchun square station has entered the construction phase plate (waiting platform).
In in Qingchun square station, located under the government of Jianggan District before the Qingchun Road, was one of the first construction site northwest section of line 2, is now one of the fastest progress of the construction site, foundation pit excavation is already good, the main structure construction stage, at this stage, has laid 3 plate (future waiting platform).
In the scope of construction in Qingchun square station has more advantages, this section of the road is wide, so is the northwest section of 11 station only a "digging" (surrounded on the fence, excavators, down from the foundation pit is dug) construction site. It is because of the construction space is big enough, the future of Qingchun square station will be the construction of Metro Line 2 in the northwest section of the track base.
In addition to in Fengqi Road Station 3 next year, April will give the good news of two lane, everyone concerned about the Wulin gate station and Ning Bridge station when started, has been affecting everyone's heart. After all, these two sites, two "throat" city within the scope of the land.
In: yesterday, reporters in the field to the scene to see, the current stadium Huancheng West Road junction, the preparatory work has been completed, the city hospital of traditional Chinese medicine Ring Road intersection position has been widened road, vehicles entering and leaving the hospital another trail. The reporter understands, Wulin gate station has begun to relocation of the pipeline, pipeline transport ready, is expected in the second half will be Weidang construction.
In the protection and Ning Bridge station is currently the No. 2 line throughout the northwest section construction most behind a site, mainly the lower Ning Bridge station main body structure is located in the school gate the road below two, the future has two entrance (a East, one West) just now in two rows of shops position. At present, the two way of Zhejiang Normal University (fine) a row of shops in front of the school has continued to remove almost, Xia Ning Bridge Station excavation, demolition of the school gate this row of shops, otherwise the station construction road width is insufficient, it is difficult to guarantee the basic traffic during construction..
Three one: in the open type shield machine successful debut power construction of Beijing subway
In: Recently, three one open type shield machine successful debut in the construction of Beijing Metro Line 6, the high price and environmental advantages to win customer recognition.
“I remember very clearly: "in the equipment comes into play, it was August 30, 2013, and eventually installed finish time is in November 10th, officially began filling soil is at noon on March 12th."For the five Bureau of iron in the Metro Line 6 of the construction team captain, leaves for the Walter spent this period of "the life" their exposure of shield machine with impressive.
In: in fact, as a senior engineering and technical personnel, leaf Walter had seen the shield machine many brands at home and abroad, but domestic equipment that he really is the first time to see. Of course, this does not hinder him for this new equipment of appreciation.
"At present we construction face geological conditions of single, it has obvious advantages over other shield machine, theoretically it can uninterrupted construction, advancing side unearthed; and soil pressure of traditional shield propulsion can not do." Yelt was excited and said, "and its price is high, because there is no driving, no tool wear."
In this table is in leaf Walter very much "model" of the shield machine, was presided over by Beijing railway construction and Management Co., Ltd., Beijing City, three one heavy machine Co., Ltd., China Railway five Bureau commitment to participate in the Beijing city of major scientific and technological projects "open type shield machine development and application of" achievement, mainly is suitable for the anhydrous or less water and soil has certain self stability of stratum, dedicated to the sand and gravel, sand and gravel, Boulder, Boulder formation instead of closed shield and shallow buried tunneling method, because of mining face open type of shield machine is open, can therefore be barriers to efficient processing of any size gravel, exploration of unknown underground pile foundation etc..
Based on the geological survey report: in the west of Beijing City, for the thick pebble stratum and gravel stratum, the general closed shield machine in the geological conditions, construction difficult, high cost, low efficiency. While the three one open shield is the manufacturing, has in the boulder area construction progress fast, low cost, surface subsidence control and other advantages, to fill the domestic blank and reached or even exceeded the international similar products.
In: to solve earth pressure balance shield, shield and other closed shield machine tunneling face huge gravel to the plight of the three one, pioneering the development of open type shield machine. In the absence of a circular cutter restriction, open the shield section can be designed into any shape is most suitable. Now, three one have the ability to develop a variety of sizes and shapes (circular, rectangular, horseshoe shape) of open type shield machine.
In the pile of shield machine in Beijing project group deputy general manager Lv Chuantian said, the actual construction data show that, compared with the closed shield machine, the purchase cost of open type shield machine will be about 70% lower, the construction cost per meter and save about 3000 yuan. "Generally speaking, the construction cost of subway is about 30000 yuan per meter, so open shield machine can save the construction cost of about 10%."
In the conventional shield machine in different, open tunneling shield machine operation is not closed, the construction personnel can assist in front of shield machine, mainly suitable for the hard soil, underground water level low cobble multi strata, used by the shield machine parts almost all the localization, the most core the pump is the use of Putzmeister, three one under the fist product, which is unique in domestic brands. The actual construction process in the long time, equipment performance showed that customer satisfaction, to evaluate the owner very high.
