Shanghai Jintai: "Diverting Water Through the Ground" for Major Water Conservancy Projects in Dawan District with Depth and Intensity
May 24, 2023
Recently，Milled by Jintai double-wheel millSX40A\SX50 and Rotary ExcavationSHThe diaphragm wall works of the water diversion well of Wuzhila Waterworks in Luotie Water Conveyance Tunnel Project, which is the pioneer in construction, have been completed.，Lay a solid foundation for the subsequent excavation of the foundation pit of the lining structure。The success of the diaphragm wall project marks the second success of Jintai Shuanglun Milling, the Pearl River Delta Water Resources Allocation Project.“Guangdong, Hong Kong and Macao”Major water conservancy projects in Dawan District have made outstanding contributions.。
Luotie Water Conveyance Tunnel-Water diversion well project of Wuzhila Water Plant
Luotie Reservoir Water Conveyance Tunnel ProjectIt is an important supporting project of the Pearl River Delta Water Resources Allocation Project in Shenzhen.，It is the backbone project of Shenzhen's water supply network.、Shenzhen City“Two-zone linkage”In a strategic context“Improve the level of public services and the quality of the ecological environment”Important water infrastructure。At the same time，Luotie project is also the first large-scale water project undertaken by the group company in Shenzhen in the past 20 years.，It has a high construction goal.、Short survey and design period、The construction period is tight、The geological conditions are complex、Complex external environment and so on.。

Water diversion well of Wuzhila Water PlantThe retaining structure is constructed by underground continuous wall.。Grooving of underground continuous wall shall be conducted by rotary drilling.（Soil layer+Rock formation），Trenching machine is used to grab the trench in the soil layer，Double Wheel Milling from 35mStart rock entry milling to 72.5m。The diaphragm wall is divided into 28 trench sections.，ⅠSequence slot segment andⅡ14 for each sequence slot section，ⅠThree-milling grooving is adopted for the sequential groove section.,ⅡThe sequential groove section adopts a milled groove。ⅠThe thickness of the underground diaphragm wall of the sequence slot is 1.2m，ⅡThe thickness of the underground diaphragm wall of the sequence slot is 2.8m;Maximum groove depth is 72.5m;The average value of uniaxial compressive strength of rock is 110Mpa，Up to 120MpaAbove。The maximum concrete pouring amount of single diaphragm wall is 524 cubic meters.，The maximum cage weight is 94.88 tons。
SXSeries Double Wheel MillingIt is one of the most important layouts in the whole series of matrix products of Jintai underground construction.，Over the years, the product has been continuously market-oriented and customer-oriented to continuously improve its own equipment capabilities and after-sales support capabilities.。In addition, to solve the customer's construction difficulties、Pain points for the project grasp and constantly break through the bottleneck of equipment development，It has taken the lead in breaking through the 100-meter diaphragm wall depth barrier in the national key water conservancy projects of many provinces and cities in China.，Up to 143m，Achieve the deepest construction record of double-wheel milling in China。At the same time，Jintai double-wheel milling is also the first domestic company to knock on the door of foreign market to realize overseas operation of domestic double-wheel milling.“Zero”Breakthrough enterprises。

Facing increasingly stringent environmental requirements，High-emission equipment will eventually be shuffled by the market，Non-standardized business units will also face accelerated elimination.。Jintai's full range of products keep up with the pace of the times and upgrade iteratively，It has now fully entered the fourth stage of the country.，Considering the future emission standards of construction machinery and the needs of the market and customers.，Jin Tai will increase the use of pure electrification.、Extensions、Hybrid product R & D investment，In order to meet the fourth national standard、And even the country five、Lay a solid foundation for the arrival of the era of six countries。
