Finally, the whole process of installation, disassembly and sinking construction of VSM equipment was successfully completed, and the problems such as high difficulty of construction organization, large amount of negative high-altitude works and longitudinal crossing of multi-layer strata were successfully solved.

Gather resources and focus on the parking pain point from the urban demand ▼ “up intelligent parking” system integrates the high-quality enterprise forces from planning, design and construction to parking equipment production, installation and operation, such as tunnel Co., Ltd., heirik, Jiangsu Zhongtai, zhongkejiabo, etc., to create a comprehensive parking solution with “self-renewal” gene, covering the assembled “intelligent” shaft Highly modular three-dimensional parking architecture, big data operation and management system, and the whole industry chain ecosystem with emerging digital field interface, innovate the traditional parking mode.

CCTV’s “news 30 points”, “economic information network”, “news studio” and other columns reported the news of the underground caisson garage in Nanjing, Jiangsu Province.

Following the trend of “smart city” and activating the power of “new infrastructure” construction technology, STEC is creating more possibilities for the city dream.

It applies the “up smart parking” system to create a new model of urban smart parking.

Four parking spaces can be parked on each floor.

STEC “super cool” smart garage makes efficient use of underground space to enable future travel, improve urban quality and development level.

In addition, the construction site shall be carefully planned in the early stage of the project, enough operation sites shall be reserved for nearby bus stations, and the traffic flow line of construction vehicles in and out of the site shall be reasonably organized to reduce the impact on bus operation.

Crossing the river by feeling the stone and constantly “breaking the situation” to promote the reform of the parking industry ▼ the caisson parking lot project in Jianye District, Nanjing is the first time in China to adopt a new type of fully automatic, undrained and suspended sinking shaft excavation method to build an ultra deep assembled shaft to build an intelligent garage.

will continue to seek the true meaning of “building a better life”, constantly promote the overall construction of public parking facilities management, and provide people with a more intelligent, safe and convenient lifestyle and experience.

As the first caisson intelligent parking garage built by VSM sinking shaft tunneling technology in China, Nanjing up intelligent parking garage project provides experience and reference for urban intensive use of land resources, development and utilization of underground space and expansion of effective supply of parking facilities.

2 deep well was completed in 45 days.

Construction Review on December 8, 2020, VSM shaft excavation equipment was unveiled for the first time in Nanjing for excavation.

On February 6, 2021, the excavation of No.

Does it have an impact on the surrounding environment? In front of Shanghai Road and bridge of tunnel Co., Ltd., it is not only the technical problem of downward excavation, but also to ensure the low impact on the environment during VSM excavation.

In order to reduce the construction impact, the whole process detection and control shall be adopted for the surrounding structures and construction noise, and the construction parameters in the VSM process shall be adjusted and controlled in real time to ensure that the settlement and noise of the surrounding buildings and roads outside the site are controllable.

From the initial stage of planning, Shanghai Road and bridge of tunnel Co., Ltd.

On December 24, 2020, VSM shaft excavation equipment began trial excavation.

On May 1, 2021, it took 28 days to complete the excavation of No.

In order to alleviate the difficulty of parking, Jianye District of Nanjing uses the corner space and adopts the vertical shaft excavation technology to build a deep shaft parking lot.

According to the organization and implementation principle of independent construction projects, professional posts adopt the “ab angle” mode, and panoramic aerial photography is taken every week.

The construction site is close to the buildings, dig deep wells and build garages.

Viewed from the outside, the parking lot is a three storey building, but two 68 meter parking wells are built under the building, with a total of 25 floors.

1 deep well was officially excavated.

More industry news can be clicked“.

In the face of the “dilemma” of no precedent and lack of experience, Shanghai Road and bridge of tunnel Co., Ltd.

This “super cool” smart garage has a total of 200 three-dimensional berths, covering an area of only more than 390 square meters.

1 deep well, with a maximum daily footage of 4.33 meters, breaking the double record of single well excavation cycle and maximum daily footage of VSM shaft excavation equipment! On November 26, 2021, the intelligent garage was completed and accepted.

At the same time, safety assurance measures such as the installation of major hazard sources on the wall, the whole process supervision of the construction process and the full coverage of the monitoring of the construction area shall be implemented.

The mechanical lifting platform can rotate 360 degrees and park on any floor, and there is no operation in the whole process.

Plan in advance and strictly control the construction to achieve low impact construction ▼ the surrounding environment of the project is complex.

On April 3, 2021, No.

strives to find a breakthrough point.

Continuous technical improvement and innovation were carried out, creating a record of completing the excavation of 68m deep space in 28 days, and witnessing the step-by-step construction and completion of the smart garage in my heart.

There are many high-rise buildings in Jianye District of Nanjing, Jiangsu Province, and the ground parking resources are relatively tight.

The total area of the project is 390 square meters, and one small vehicle can be used to drive in and out of the sunken area of Shanghai by using the “95 square meters of sunken shaft” project, with an average of 390 square meters, It takes only 90 seconds to provide a high-quality parking experience.

Recently, the first caisson intelligent parking garage constructed by VSM sinking shaft tunneling technology undertaken by tunnel shares Shanghai Road and bridge successfully completed the construction task in Nanjing, Jiangsu Province and entered the internal trial operation.

has made clear the requirements of low impact, and continuously refined and optimized construction management measures in the subsequent construction process.
