Enter the construction site of Shenzhen Wuhe Station，A busy scene came into view.，Dozens of large rotary drilling rigs in the site、Grooving machinery、Full slewing drill、Large crawler cranes and other foundation construction equipment are under intensive and orderly construction.，And that piece of“Mountains and rivers are green”It's even more eye-catching。

The hub of Wuhe Station in Shenzhen is Jishenda.、Shenhui、Central axis, three intercity lines and subway 5、Line 10 is a large-scale integrated transportation hub.。Radiate the eastern part of the Bay Area，Contact Guangzhou to the north、Dongguan，Contact Hong Kong to the south，Eastward linkage with Huizhou、 Zhongshan ，In the future, it will be the most important inter-city hub node for Shenzhen to connect the core cities of Guangdong, Hong Kong and Macao.。To promote the high-quality development of Shenzhen's external groups、Fill in the blank of Shenzhen East-West Wing Intercity Axis、Improve the passenger distribution system of Shenzhen Baoan Airport、It is of great significance to build a high-quality international aviation hub.。

Station master 955.6 meters，Standard section width 61.5 meters，Buried depth of floor is about 36.3~52.7 meters，It is an island station with four underground floors and five local floors.，The main building area is about 22.680,000 square meters，The auxiliary building area is about 1..10,000 square meters。

The station support system is 1.Beam and slab structure with 2m thick continuous wall and permanent and temporary composite frame，Permanent and temporary combined ring plate support open-cut method shall be adopted for the whole.、Cover excavation method、Pipe jacking method、Combined construction of various construction methods such as local underground excavation method。Sunward intelligence includesSWDM1000、SWDM600、SWDMNine sets of super-large drilling rigs, such as 550, participated in the site construction.，AmongSWDM1000 type super rotary excavation is the largest model in this rotary excavation construction.、Drilling rig with the strongest construction capacity，And the rotary drilling rig“ Master ”-Wuhan Lecheng Construction Engineering Co., Ltd.，It is also the highest score of the project department by virtue of this equipment.！It is reported that，Wuhan Lecheng Engineering Co., Ltd. entered the project in October 2023.， With the help of Sunward Intelligent Rotary Drilling Rig，The hole-forming speed is increased by one times，Verticality is also the greatest recognition in the whole project.！

The strata within the station are as follows from top to bottom：Su(Miscellaneous)Fill soil、Gravelly cohesive soil、Gravel sand、Completely slightly weathered granite，The base is located at the full~In slightly weathered granite，The maximum uniaxial compressive strength of slightly weathered granite is more than 180Mpa。The design of station pile foundation is mainly based on steel column pile.，Pile diameter includes 2.2-3.2 meters and other specifications，The depth of hole-forming construction is about 60 meters.，In need of drilling、Breeze granite layer about 40m。The depth of pile foundation construction into the rock is large、The rock strength is high，And that steel column pile put forward higher requirement for the verticality of the hole for by the equipment.，The construction capacity and efficiency of rotary drilling rig are the key factors to ensure the high-quality development of the project.。

Step reaming process shall be adopted for on-site rotary excavation of rock，Sunward intelligenceSWDM1000 type rotary drilling 3m pile diameter，Three-stage reaming shall be adopted for rock entering construction.，Proceed 1 first.8m large diameter coring，The latter part is 2.4 meters、3m twice expanding，The length of single coring is about 3m，The rock integrity is good，The coring rate is high，SWDMIt takes about 12 days to form a hole for 1000 single piles.，Drilling efficiency into rock、The hole sag and the construction stability of equipment are the best in the field.。
