Shanghai Regional Railway Jiamin Line ushered in new progress in construction!

Introduction to Shanghai Shentie Investment Co., Ltd.，Recently，Shanghai Regional Railway Jiamin Line Welcomes New Progress in Construction！April 11，As the reinforcement cage of the last diaphragm wall enters the groove smoothly,，Construction of Enclosure Structure Diaphragm Wall of Yingbin 3rd Road Station of Bid 15 of Jiamin Line Ends Safely and Smoothly。In addition，April 12，Jiamin Line 8 Bid 1#The first five diaphragm walls of the main enclosure of the air shaft passed the acceptance test smoothly.。See for details↓

Bid 15 of Jiamin Line

Diaphragm Wall Construction Ends Successfully

Lot 15 of Jiamin Line includes one station, two sections and one section of cable tunnel works.，The total length of the bid section is about 2.28 kilometers，It is an important link connecting Hongqiao hub.。

Hoisting of reinforcement cage for the first diaphragm wall of Bid 15

Yingbin 3rd Road Station is the two-way departure station of this section.，Complex geological conditions of the project site，Most of them are muddy soil.、Sandy silt，The formation is rich in water，Fluid-plastic，Has high compressibility、Low strength、Low permeability、High sensitivity and poor stability，At the same time, the working surface of the construction site is small，There are many equipment and machinery，Complicated cross operation procedure，High risk of operation safety，All these put forward high requirements for the construction of diaphragm wall.。

Difficulties in project construction，Shanghai Shentie Deploys Ahead of Schedule，Jointly with the construction party, organize the project team to formulate various plans in detail.、Careful organization and scientific implementation、Ensure the safe and smooth progress of all construction tasks of the project。

Hoisting of reinforcement cage of the last diaphragm wall in Bid 15

The first reinforcement cage has been hoisted since December 3 last year.，The project department has overcome land acquisition and demolition.、Pipeline relocation、Construction height limit、Difficulties in preliminary work such as traffic diversion and the impact of the epidemic，Reasonably adjust the construction plan，Optimize resource allocation，Further clarify the responsibility objectives，Finally, the construction of all 106 diaphragm walls of the enclosure structure was completed with quality and quantity guaranteed.，It creates favorable conditions for the subsequent construction of the main structure.。

Bid 8 of Jiamin Line

1#The first five diaphragm walls of the air shaft passed the acceptance test smoothly

Bid 8 includes Fengmao Road Station（Not included）To 1#Air Shaft（Contain）Shield section and 1#Air shaft structure，Of which 1#The air shaft is an underground two-layer air shaft，The total net length of the air shaft is 25m.，Clear width of standard section 13.9 meters，Excavation depth of foundation pit at main body of air shaft 24.8 meters，Excavation depth of channel and auxiliary structure 12.0 meters。

During the acceptance process，The five parties involved in the construction conducted an on-site inspection.，After listening to the acceptance report in detail and consulting the relevant materials,，Satisfied with the construction result，The trench verticality and filling coefficient of the first 5 underground walls meet the requirements of the acceptance specification.。

With the successful acceptance of the first five diaphragm walls,，It also marks that the project will enter the peak period of diaphragm wall construction.，At the same time, it also puts forward higher requirements for the construction tasks in the next stage.。 Information ：Shanghai Shentie Investment Co., Ltd.
