Stable + Efficient + Fuel Saving! Sany rotary excavator group helps the intercity construction of Shenzhen University

Recently, Sany rotary excavator group participated in the construction of Shenzhen Shenzhen University Intercity Project 2 Standard Wuhe Station, and the project site gathered Sany SR415, SR445, SR525Pro four large tonnageRotary drilling rigs, responsible for the construction of Wuhe station pile foundation.

The Shenzhen section of the Shenzhen-University Intercity Railway not only traverses the east and west of Shenzhen, seamlessly connecting 20 subway lines, 5 intercity railways, and 4 high-speed railways, but also can transfer to the airport APM line and Pingshan Yunba line. The project is also an airport rail express line to improve the passenger distribution system of Shenzhen Bao'an International Airport, expand the airport's eastward radiation capacity, and build a high-quality and innovative international aviation hub

Guangdong Nianxin Construction Engineering Co., Ltd. brought Sany SR415 and SR445 into the construction at the beginning of the year, and was well received by customers for its excellent rock entry performance and stable equipment status. Later, two Sany SR525Pro large triangle luffing structure drilling rigs were successively purchased and put into use.

The construction pile diameter of Wuhe Station is 3.2 meters, the pile depth is 65 meters, the upper solitary stones are scattered and scattered, and the number of bored solitary stones is as many as 10. The substrate is mainly located in strong ~ slightly weathered granite, and the rock strength is 150MPa. The picks are drilled with the cone barrel drill at four stages, and the maximum depth of a single pile is 55 meters of core. This puts forward higher requirements for the construction of rotary drilling rigs.

Sany SR415, SR445 and SR525Pro use high-power and large-displacement engines, and the power is distributed in real time according to demand, and the continuous output is to cope with the rock entry conditions. The main winch has a large lifting force, and can calmly cope with underground emergencies. It is equipped with a double-turn reducer to ensure that the hole is not deviated, and is equipped with an intelligent control system, which can realize the automatic adjustment and display of the verticality of the drill mast, which effectively ensures the stability of the hole wall and the quality of the hole during the construction of the pile foundation. The core capabilities such as pressure, torque, and lifting force are perfectly matched to achieve efficient drilling of hard rock, deep holes, and large piles, without fear of slightly weathering hard rock.

The project is located in the urban area, and there is a time limit for urban construction, so there are higher requirements for the stability of the equipment. The comprehensive attendance rate of Sany's rotary drilling rig is as high as more than 90%, and it has achieved "the operator changes shifts, and the equipment does not get off work", which is a proper full attendance award. At the same time, Sany service engineers are on call 24 hours a day, and the after-sales service is guaranteed, and the construction is more secure. The customer commented: "For us, time is money and efficiency generates value. Sany equipment is stable and efficient, and we plan to purchase more Sany products in the future! ”

The customer's repurchase is the best endorsement of the brand. Sany rotary drilling rigs will also continue to help the construction of major transportation projects, create value-added value for customers, and establish guarantees for major projects.
