Recently，By Kim TaeCSMJieneng participated in the construction of double-wheel mixing equipment SF1103-127-More than 300 piles have been successfully laid in the residential project of Plot 1.，It is expected that all 475 will be completed in mid-September.CSMConstruction method pile。
Jieneng SF1103-127-Plot 1 Panorama
Jieneng SF1103-127-Plot 1 Residential Project is located in the north of Zhengzhou Road, Shibei District, Qingdao City、South of Licun River、East of Route 4，West of Route 6。According to the drilling，The stratum of the survey site is mainly composed of Holocene artificial fill layer and Holocene pluvial-alluvial deposit.，The bedrock is mainly composed of late Yanshanian granite.。The formation structure of the site is simple.，The sequence is clear。Top-down geological stratification is as follows:：①0-3mBackfill construction waste、②3-9mWater-rich coarse sand layer、③9-11mClay、④11-14mCoarse sand、⑤14-16mArgillaceous sandstone and highly weathered。

Kim TaeSC35\SC55\SC55BThe double-wheel mixing rig is the main wall-forming equipment of the proposed site.。The construction pile depth of the site is 14-16m，Slot width 700mm,2500 longmm，The average working state of each equipment can complete 7-8 piles，More than 300 pieces have been completed.。It is understood that，The construction site has a large number of water-rich sand layers and is close to the seaside.，Groundwater permeability is strong，There is a large area of pond in the site.，After nearly 20 days of water stop construction,，The water level dropped significantly，And that wat stopping effect is remarkable。
Shanghai Jintai has been the first since 2011.CSMConstruction equipment has been used for 12 years since it came out.。In Shandong，Kim TaeCSMThe application of the construction method also has 9 years of precipitation.，Kim TaeCSMDouble-wheel mixing equipment has been widely concerned from the little-known of Boxing Reservoir in Shandong Province in 2015 to the joint operation of 11 double-wheel mixing rigs in Dongying Reservoir in 2017, and now to Wenfeng Road Station of Qingdao Metro.、Zhoucun station、Jingdai station、Former Dongcheng Station、China Shipping Group Shibei District Housing Construction Project and so on.，Jintai on the land of QiluCSMDouble-wheel mixing equipment involved in a wide range of engineering categories，Including industrial and civil construction、Rail transit construction、Prevention of soil pollution、Water conservancy projects, etc，The deepest practical application case reaches 53.5m，Be known as“The first depth in North China”。

Kim TaeCSMThe working method is an innovative double-wheel mixing drill combining hydraulic slotting machine technology and deep mixing technology.。Since its inception，Already in the Yangtze River Delta in China、Zhongnan is along the Yangtze River、Pearl River Delta、And Shandong、Nearly 400 projects in more than 20 provinces and cities such as Heilongjiang have been fully verified and construction experience has been absorbed.，Thereby developing a Rotary Drilling Rig type、Electro-hydraulic crawler、Lectro-hydraulic walk type three-type main engine platform，Can cover 20mTo 65mDepth，Can cope with dense sand layer、Coarse pebble layer、And a series of soft rock formations within 10 MPaSCProduct cluster。And becauseCSMThe construction method can completely mill the original wall.，More adaptable to irregular contours，Relatively environmentally friendly，The stability of the equipment is strong，High construction efficiency and other characteristics provide a strong guarantee for later foundation pit excavation.。
