All the way to the west, Shanghai Jintai CSM construction method equipment construction layout is expanded again.

July 24, 2024

The other day,Six fully loadedSCThe large cargo Truck of the main engine and components of the 45 hydraulic milling and mixing drilling rig went all the way westward from the headquarters of Jintai Anting in Shanghai to the new battlefield.。A week later,The convoy arrived in Delingha City, Qinghai Province.“Dynamic balance ecological environmental protection upgrading and transformation project”Construction site。Unload、Assemble、Debug at one go,After a simple opening ceremony.,SC45 Steadily drive onto the dam foundation and take its place,Put in immediately 3#Construction of anti-seepage wall of retaining dam。In the blue sky、 White cloud 、Against the background of the deep lake,It is particularly dazzling and beautiful.。This is the first introduction in Qinghai Province.CSMThe construction method is applied to the construction of ecological environment protection projects.,Marking Shanghai JintaiSCHydraulic Milling Drill Set a New Milestone in the Infrastructure of the Motherland。

SCThe 45 double-wheel mixing drilling rig was put into operation immediately after the simple commencement ceremony.

As early as 2009, Shanghai Jintai has started research and development.CSMConstruction method and equipment,The first prototype rolled off the production line in July 2010,In August of the same year, it was approved by Hubei South-to-North Water Diversion Construction Administration to be applied and verified in the sluice foundation treatment project of Xinglong Water Conservancy Project.。Since then, this construction method has gradually expanded from water conservancy anti-seepage reinforcement projects to the waterproof curtain of urban building foundation pits.、Prevention of underground pollution、Large bridge anchorage foundation pit trench wall reinforcement and the like.,The application area has also expanded synchronously.,North to Heilongjiang、South to Hainan Island、East to Jiangsu, Zhejiang and Shanghai、West to Xinjiang,It covers almost all provinces in the country.。In the process of promotion,Shanghai Jintai is based on the geological characteristics and design requirements of the project conditions.,Tracked diesel main engine has been developed successively.、Crawler electro-hydraulic main engine、Three types of walking electro-hydraulic hostSCSeries platform products。According to incomplete statistics,Kim TaeSCSince the application of series products,More than 500 adaptability projects have been completed throughout the country.。

August 2023 Kim TaeCSMThe construction method is included

This time in Delingha City, Qinghai Province“Dynamic balance ecological environmental protection upgrading and transformation project”,Original 3#Geomembrane is adopted for the dam foundation of retaining dam+Anti-seepage technology of continuous high-pressure jet grouting pilot,Masonry slope protection shall be adopted for the upstream face.,Dry masonry slope protection shall be adopted for the back water surface.,The dam body is 641 meters long.,Top width of dam body 12.5 meters,The dam foundation is 58 meters wide.,After reinforcement of the dam body,,Realize structural stability of the dam body。During the construction monitoring, it was found that there was obvious leakage at the connection between the high-pressure jet grouting pile and the geomembrane.,After re-investigation and demonstration,,The construction scheme is changed to the present“Adopted at the dam crestCSMImpervious wall construction by anti-seepage technology“,To prevent and control soil erosion,Reduce the pressure of the dam body,And that safety of the dam body is ensure,The design Institute is in 3#A 4-meter-deep intercepting ditch and two collecting wells have been built on the downstream side of the dam body.。

 Delingha City, Qinghai Province“Dynamic balance ecological environmental protection upgrading and transformation project”-3#Project overview

At present。The project is progressing in a tense and orderly manner.,Project department to Kim TaeCSMThe construction efficiency and wall-forming quality of the construction method and equipment are unanimously affirmed.。BecauseSCA successful demonstration of 45,To speed up the progress of the project,The project department has gathered another 7 Shanghai JintaiSCHydraulic milling and mixing drill、3 setsSGA series of Hydraulic Grab arrived at the scene one after another.,Foreseeable,The follow-up project will be more efficient、Faster。

Popular Science of Professional Knowledge:

Intercepting ditch,‌It can effectively intercept rainwater or groundwater on hillsides.,‌Prevent water flow from directly scouring the dam body,‌So as to protect the stability and safety of the dam body.。‌In addition,‌The intercepting ditch can also reduce the direct impact of rainwater on the dam body.,‌Reduce the water pressure on the dam body,‌Enhance the flood control capacity of the dam body。‌

Collecting well,‌The water flow intercepted by the intercepting ditch can be effectively introduced into the water collecting well,‌The water is then drained through a drainage system,‌Avoid the water flow staying around the dam body for a long time,‌Reduce erosion and damage to the dam body。‌At the same time,‌The setting of collecting well is also helpful to observe the leakage of the dam body.,‌By monitoring changes in the water level in the sump,‌The leakage of the dam body can be found in time.,‌Provide the basis for the maintenance and management of the dam。

‌The construction of intercepting ditches and collecting wells not only helps to protect the stability and safety of the dam body,,‌It can also effectively reduce soil erosion.,‌Improve the flood control capacity and service life of the dam body。‌
