Overcome Technical Difficulties, "Dream of Add Ladder" for Residents Above Round Tunnel"

It turns out that these residential buildings are under the Longyao Road tunnel. During the tunnel shield construction period, the residents moved and transitioned. By 2020, the tunnel will be completed and opened to traffic. After the relocation, the residents applied for ladder addition. "Shanghai has never had a precedent of adding ladders directly above the tunnel. According to the requirements of the" Technical Guidelines for the Installation of Elevators in Existing Multi-storey Residential Buildings ", piling technology is required for the addition of ladders in existing multi-storey houses, which will cause damage to the tunnel., Does not meet the implementation conditions." Lu Yayong, director of the Urban Construction Management Affairs Center of Shanggang Xincun Street, said, "But no matter how difficult it is, we have to fight for the old people's dream of adding ladders."

Liang Ming, head of the Architectural Design Institute of Shanghai Kan Group, remembered that eight times had been held before and after the scheme seminar alone-"Ordinary elevator installation uses pile foundation, and piling may need to be 20 to 30 meters deep. Because the tunnel of our project is 15 to 18 meters below the house, piling is not feasible, so we adopted compensatory foundation, within 15 meters between the tunnel and the building, expand the base."

The reporter learned that the so-called "compensatory foundation" means that the elevator pile foundation does not need space to the depth, but expands the transverse surface of the base to lay a solid foundation for the elevator and ensure the safety of the tunnel. Liang Ming said that behind the small step in the optimization of the plan is a big step taken by various departments to overcome many difficulties and jointly tackle tough problems, turning "unfeasible" into "feasible"-"We need to monitor and monitor all aspects of the tunnel. Some work, so that after the installation of elevators in this project, the additional stress on the tunnel will reach a safe range, within the allowable range."

Running out acceleration of whole process service and ladder adding work

Technical problems have been solved. How to do a good job in residents' work is even more testing the ability of grassroots governance. There are 46 residential communities in Shanggang Xincun Street, and the old communities account for 80%. Many of them are "suspended elderly people". For them, the landing of each elevator may be the beginning of a new life.

Lu Yayong provided such a set of data. Last year, the streets completed the signing of 72 additional ladders, ranking first in the region. Another 30 units were started and 20 completed, 240 of the original plan.

How does the acceleration run out? Huang Yanchun, Secretary of the Party Working Committee of Shanggang New Village Street and Director of the Working Committee of the National People's Congress, summed up the efforts of the past year as-serving the whole process in every detail. In order to speed up the installation of elevators in old residential areas, Shanggang New Village has set up a special "ladder adding leading group" at the street level, set up a special work class, and set up four working groups, namely, the mass working group, the procedure guidance group, the safety responsibility group and the information publicity group, to realize the full participation and full service from the beginning of signing the contract to the final delivery.

On the other hand, the street actively mobilizes the general party branch in residential areas, takes the "troika" as the core, extends the party building work to the front line of the work of adding stairs, and establishes a four-level contradiction mediation mechanism of "building group", "residential group", "street special class" and "street leader", conducts household consultation on individual situations that disagree on the first floor, and reaches an agreement. The secretaries of various residential areas also have their own magic weapons and deep feelings. "In the process of adding ladders, we will combine the construction of beautiful homes. For the residents on the first floor, we will add ceramic tiles and floor tiles in the corridor. In some buildings, we will add a non-motor vehicle shed at the entrance of the building, and the environment will be improved at once." Dezhou four village residential area secretary Zhu Lan said.

"One Floor, One Plan" Explores "Full Life Cycle" Management Mode

On this basis, Shanggang Xincun Street also carried out a full coverage of 1877 buildings in the area, and formed a "one floor, one plan" according to different situations, realizing the transition from "people and other plans" to "plans and others". Lu Yayong said that Shanggang is still exploring the "full life cycle" management model, and the improvement of every link in the installation process is to give residents a better sense of experience and make more people willing to install elevators. At present, the streets have formed a closed-loop management system for the consultation, approval, construction, acceptance, and use of elevator projects. According to the characteristics of the old residential areas in the jurisdiction, Pudong Development Housing Management Company is entrusted to undertake the post-maintenance work of existing multi-storey residential buildings and assembled elevators, forming an integrated management "steel-on mode".

Work to sink, in order to let the elevator "stand up". In recent years, Shanggang Xincun Street has conscientiously implemented the concept of people's city and concentrated its efforts on doing a good job in people's livelihood. In 2023, a total of 72 additional elevators were signed, ranking first in the region in terms of the number of contracts signed. In the past three years, a total of 123 elevators were signed. Huang Yanchun introduced that in the next step, Shanggang will continue to promote the installation of existing multi-storey residential elevators as a "popular project". Through the "key small matter" of adding elevators, it will promote the solution of residents' "livelihood issues" and effectively improve the quality of life of community residents., So that more community residents can enjoy the convenience and benefits of "the first step of going out every day and the last step of going home.
