31 Self-developed Continuous Wall Grab Lead The Trend Of Subway Equipment - 31, Continuous Wall Grab

China has entered a peak period of construction of rail transit

, metro cities in the country began to rapidly paved, subway equipment manufacturers vying for market share has become the new target. Underground space development is mainly the depth of the basement before the structure can be traditional maintenance pile, but the underground resources now in order to save two, three-tier structure gradually increased, maintaining a depth of 60-70 meters underground, while the indigenous methods generally applied to 12 meters, underground continuous wall is completed to maintain the best solution is to adapt our continuous wall grab the best equipment, subway construction project!

Heavy Machinery Co., Ltd. Beijing 31 grand launch of the first units to upgrade SH400C continuous wall grab, in the Tianjin Binhai New Area Jiabao transport hub after the high-profile appearance, advanced technology, quality service in one fell swoop Bureau of iron 16 high degree of recognition. January 27, "cast-quality work beyond" heavy machine Beijing 31 continuous wall grab Seminar held in Tianjin Binhai New District, Beijing, 31 heavy machine marketing general manager of Mr. Cheng Hua, Beijing, 31 heavy machine Chih-Ming Lin, general manager of continuous wall Mr. Dean Mr. Xu Xiaodong and other company leaders, as well as 31 heavy machine national customers showed up, HC Engineering Machinery Network Editor witnessed 31 continuous wall grab the style!

Subway equipment facing "exam" 31 "take priority"

Jiabao stop is Tianjin Binhai New Area 3 subway lines and the Beijing-Tianjin inter-city project to extend the line of convergence of the hubs, China Railway 16 Bureau is responsible for the civil works construction of the Fourth Contract Section. 16, Executive Manager and Chief Engineer Zhang Tao introduced Jiabao transport hub in engineering large, complex geological environment, security risks of higher difficulty, for the diaphragm wall trench very unfavorable. First, the project is large in scale and short construction period, the main structure of building area over 60,000 square meters, 60 meters deep underground, to build 93 continuous wall, the wall depth of 60 meters, 1.2 meters thick and a single width of 5 meters, with two years completed. Second, the project hydrogeological conditions are poor, about 20 meters for the upper silty soil, plastic and permeability is poor; the lower part of about 38 m thick for the sandy soil, high permeability and hardness; groundwater level as high as 0.5 to 1.5 meters, with sulfate corrosion. Third, the ultra-deep diaphragm wall of the trench required a high degree of vertical, precision control is difficult, easily collapsed tank, infiltration and so on.

"Hub Jiabao continuous wall trench construction difficult, is the metro project in the country the most continuous wall construction, the equipment requirements were very strict, one must ensure that grab the weight, second, on the basis of the performance guarantee stability verticality accurate, three to have a good correction system, "Zhang said work. 16 Authority from August 25, 2009 entered Binhai New Area, the formal construction in October, has now been completed diaphragm wall 56. The greatest contribution of which is 31 SH400C continuous wall grab, more than two months to complete eight, compared to other 4 sets 2-3 average monthly rate of increase construction performance, 31 surrendered a satisfactory answer. Zhang Gong introduced, initially using 31 continuous wall grab is questionable, however, just two months after contact had been completely continuous wall grab 31 advanced technologies, construction effects, and 31 were attentive service and thoughtful the steam. Zhang Gong said diaphragm wall grab in the domestic development time is not long, underground engineering is the future direction of development, continuous wall grab promising.

31 continuous wall grab "low-cost construction of self-developed brand"

SH series of 31 consecutive wall grab is currently the independent research and development, with independent intellectual property rights, the only CE certified national brand with export rights; to work method-oriented, low-cost construction led the market is efficient, energy saving, the next generation of environmental protection foundation construction equipment. Development and production since 2006 since the product a total of four models: SH400C, SH400, SH350, SH500. SH400C diaphragm wall grab on a number of structural improvements in performance has greatly enhanced the efficiency of both the trench or trench has a significantly improved accuracy.

SH400C Features continuous wall grab

1, high-reliability: use of imported brands of six steel wire hose, new machining roller, high wear-resistant steel sets of new gear maintenance-free, high strength and impact resistant guide plate, reinforced paper tube device to increase the life of the equipment, factory conditions and strict demands simulation experiments, reduce the failure rate.
