Sany auger to build Shanghai Kunming high-speed railway boutique project
Guide: at present, China's East-West high-speed railway, which has the longest route mileage, the largest influence range and the most provinces, has entered the stage of full-scale construction. With the construction climax, Sany rotary excavation was carried out in important construction sections such as Jiangxi Shangrao railway station, Guixi construction site, Nanchang Bayi Bridge, Nanchang West Railway Station, etc
at present, Shanghai Kunming high speed railway, the East-West high-speed railway with the longest route mileage, the largest influence range and the largest number of provinces in China, has entered the stage of full-scale construction. With the climax of construction, Sany rotary drilling rig has contributed one excellent project after another to the pile foundation construction of Shanghai Kunming Railway with high-quality performance and perfect service in important construction sections such as Jiangxi Shangrao railway station, Guixi construction site, Nanchang Bayi Bridge, Nanchang West Railway Station, etc
Sany equipment at the construction site of Shanghai Kunming High Speed Railway
technical support
construction efficiency increased by three times
in the cenganghe Super Major Bridge in Shangrao section of Shanghai Kunming High Speed Railway undertaken by China Railway fifth Bureau, the equipment purchased by the customer zhanjiqing undertakes the construction task of pile foundation with pile diameter of 1.8m and pile depth of 44m. As the production and operation of guest enterprises are also faced with many difficulties and problems, the customers' inaccurate grasp of the geological conditions has led to the rich results of the "three campaigns" of the non introduction, commencement and production of drill pipe and drilling tool configuration, as well as the unreasonable operation of machine hands, which have affected the construction efficiency
in view of these problems, the construction engineers put forward corresponding solutions, fully communicate with the manipulator, teach the manipulator the drilling methods and skills of relevant rocks, use the point pressurization method to drill, and try to increase the pressure and shorten the time of single pressurization under the condition of maintaining a certain speed, so as to obtain greater cutting force
"Because the equipment needs to be embedded in sandstone and limestone for more than 30 meters, other brands of rotary drilling rigs and percussion drills have failed to leave the site before. Through the on-site guidance of Sany construction method experts, our construction efficiency has been greatly improved, from 10 days to 3 days, the machine efficiency has been increased by 3 times, and the output value of a day has increased by 10000 yuan. This is the third Sany rotary drilling rig I bought Dig the drill. " Customer Zhan Jiqing said to
set up service points nearby
fully guarantee the construction
in the Shangrao railway station expansion project through which the Shanghai Kunming railway passes, there are a total of 11 Sany rotary drilling rigs, accounting for 70%. In order to provide customers with more timely and deeper services, Beijing pile machine set up a detection electromagnetic clutch Service Office in Shangrao in October 2010, equipped with 4 service engineers, 1 service vehicle, so as to avoid oil leakage (water) and various accessories; Regularly arrange construction methods and after-sales engineers to inspect the machine, and interpret the "three fastest" after-sales service goals of the fastest arrival at the site, the fastest problem solving, and the fastest parts supply with high-quality service
"this is my first time to use the rotary drilling rig, and I don't know much about the equipment. From the purchase of equipment to the assembly of equipment, pile testing, manipulator training, machine maintenance, etc. during the first construction, engineers from Sany method, customer service and other departments have provided me with full service. The establishment of nearby service stations can also quickly solve the on-site construction problems and solve my worries." Customer Chen Shilian said
as one of the national "four vertical and four horizontal" fast passenger transport channels, the Shanghai Kunming high-speed railway starts from Shanghai in the East and ends in Kunming in the west, with a total length of 2066 kilometers. The whole line is a double track electrified railway, with a total investment of more than 300 billion yuan. (Sany CHEN Ye)
