Shanghai Jintai Large Rotary Excavator Delivers "New Answer Sheet" 60 Days Ahead of Schedule, More, Faster, Better, More Economical and Innovative Construction Record
September 22, 2022
September 817:00 p.m，Jintai Large Rotary Drilling Rig Completed the Last 143 in Shanghai-Suzhou-Jiaxing Intercity Railway ProjectmCast-in-place pile construction，It is the first large-scale Rotary Drilling Rig to complete the construction task of super-large deep piles on site.，The construction was completed 60 days earlier than the planned construction period.，Refreshing the construction record of super-large deep piles of the product itself。
Shanghai-Suzhou-Jiaxing Intercity Railway Project - Jintai Large Rotary Drilling Rig Site
Shanghai-Suzhou-Jiaxing Intercity RailwayIt is connected to Shanghai、Intercity railway between Suzhou, Jiangsu Province and Jiaxing, Zhejiang Province，It is 170 kilometers long，The design speed is 160 kilometers per hour。 The railway is the power core of Hongqiao Business District in the series demonstration area.、Qingpu New City、Innovative Green Core around Dianshan Lake、Xicen Kechuang Center、The living room of the water village、Xiangfudang Innovation Green Valley、Key transportation links in core functional areas such as Kechuang New Town of Wujiang High-speed Railway，Achieve 30-minute access between important function nodes。The whole line has been included《Multi-level Rail Transit Planning in the Yangtze River Delta Region》。
ByJintai large rotary drill is responsible for the construction of the bearing platform.，120mThe main strata above are clay and fine sand.，Over 120mAfter entering the ultra-deep formation, there are 30mDeep，Granite with a hardness of more than 70 MPa。Design depth 143m，Aperture 2.5m，Construction accuracy 3‰Within。This construction condition makes the already difficult project even more difficult.。
August 12，Jintai Large Rotary Drilling Drill Welcomes the First 141 of Shanghai-Suzhou-Jiaxing Intercity RailwaymTest pile of super deep pile is successful.。After the hole is finished, the staff of the project department shall immediately inspect its verticality.，The test results are shown in the figure below.。Absorb the valuable experience of the first pile，Real-time data comparison between Jintai aftermarket service personnel and technicians on the spot，Drilling tool ratio，Continuously optimize the construction scheme，Strive to improve the original construction efficiency.。
The first deep-hole pile of the project“141m”Ultra-deep wave detection
After formal punching，The initial upgrade plan has achieved remarkable results.，Hole formation for the second pile 141.74m，The measured construction time is 5 hours faster than the first pile.，Fuel consumption is also more than 2 liters per hour than the first pile.，In the successive pile-forming construction,，Efficiency and energy-saving performance are gradually improved as designed.。As of September 8，Jintai completed 30 large rotary drills with a depth of 138~143mA huge deep pile，From the final result of the completion,，The results delighted all the staff and users present.。Jintai Large Rotary Drilling Drill Has Outstanding Ability，The efficiency is 30% higher than that of the large rotary drilling rig of the same level on site%，Fuel consumption also saves 3000 yuan per pile compared with the same level of rotary drilling rig.，Users are very satisfied with the excellent performance of the equipment in the project.，Intends to start another Jintai rotary drilling rig to participate in the construction of the project。
Kim TaeSH60 and above large、The super-large rotary drilling rig is imported.CAT-C18 Engine,The main hydraulic parts are all international first-class brands.，Power system and hydraulic system are perfectly matched with efficient output.，It fully guarantees the quality and ability of Jintai piling products.。The overall design is unique，Reflect the international advanced compact style，And that effective output pow is greatly improved.、Rock entry capability and fuel economy，It is the preferred equipment for the construction of various super-deep and super-large pile foundation projects.。
Jintai is the earliest manufacturer of complete underground construction solutions in China.，At present, he has made outstanding contributions in many fields of foundation construction.，Such as：SCDouble-wheel mixing rig won the second prize of National Science and Technology Progress Award，SXDouble-wheel milling achieves the deepest 143 in ChinamDiaphragm wall construction，SGSuper Engineering of Hydraulic Grab Bucket Directly Grooving 100 Meters，SHLarge rotary drilling rig breaks through 140 for the first timem+Super deep pile and so on。Jintai pile products are constantly proving themselves with a super project.，Whether in terms of construction efficiency or the ability to overcome complex formations.、Energy saving、Reliability and other aspects are good products worthy of users' trust.。
