The vertical elevator of the bridge in Shanghai should be installed. Why is there a special case?Relevant departments have emerged for the reason →

Yan'an West Road Kaixuan Pathfall Passenger Travel Bridge

It is a must -have channel for many citizens to travel

Recently, it has some new changes

▽

There are four corners of the southeast, southwest, northwest, and northeast of the overpass. The high frames extend from the ground to the viaduct. The vertical elevator to be built has begun to take shape.

This year, the Shanghai Practical Project has arranged 38 people's crossing bridges and staircases to provide a more temperature travel environment for the disabled people and the elderly. As of now, Qixia Road, Dongfang Road, Tianqiao, Chongqing South Road, Zhaojiabang Road Wanping Road Field Bridge, Beizhai Road Union and Tianqiao have completed the addition and run.

As part of urban renewal, elevator projects that seem to occupy a large area and are not complicated are actually not easy to build. Not only must you flip in the cramped space, but you may also encounter some "unexpected".

In this regard, the relevant parties are moving their brains, and under the guidance of innovative policies, the expectations of citizens will land as soon as possible.

Space, still space

On the Yan'an Road, the seven -seater city management flying bridge from east to west is included in the gradient plan. At present, construction has been started. They have an interesting name- "Seven Gourd Baby".

"At present, there are 264 flyover in Shanghai. Among them, 133 vertical elevators or escalators are installed." Jin Xi, the person in charge of the Pedestrian Bridge of the Municipal Daoming Center, introduced that the 38 crowded bridge planned to add ladders this year is in this year. After considering a number of factors, determine. For example, whether there are large transportation hubs, schools, hospitals, and residential communities in the area of ​​500 meters around; whether there is a cross -street cross -street way within 100 meters; whether the safety demand for crossing the street is more obvious, and so on.

From the point of view, the vast majority of these flyover are located in the center, and the "Qiwa" of the city management is on the Yan'an Road of the car. Although the elevator looks not large, the land in the central urban area is tight and the underground pipe network is complicated, and the builders need to flip in the cramped space. In addition, in order to meet the needs of urban aging, vertical elevators should be installed as basic criteria. Compared with the escalator, the foundation of the traction equipment and the protection of the pipeline is more difficult and the investment is greater.

Take Yan'an Road Tibet Road, for example, after the on -site exploration, it was found that the underground of the stairs on the west was between the shield tunnel of Line 1 and 8. "Because of the safety of the subway operation, there was only one choice left at that time -demolished the original stairs, set the point in the gap, and rebuild the stairs and vertical elevators." To this end, the Municipal Taoism Center repeatedly opened the Shentong Metro and repeatedly opened the Shentong subway repeatedly. More than a dozen meetings demonstrate that at the time of construction, the vertical elevator pile foundation is set in the middle of the two tunnels. The minimum of each other is only three meters interval, which is equivalent to a lane on the ground.

Sometimes, some vertical elevators are even "nowhere to place." At the end of August this year, Zhaojiabang Road, Wanping Road, who opened the elevator at the end of August this year, encountered such a "hard bone". In its three quadrants, only the northwestern quadrant has room to add vertical elevators. If other quadrants are installed with vertical elevators, you must dig down 2 meters down to set the traction device. However, underground pipelines such as electricity, gas, water supply, and communication, especially between ultra -high -voltage power and gas pipelines, must be kept safe.

The pipeline shift is not connected, and the vertical elevator can only be abandoned and the escalator can be set up through the ground lifting. So, how to avoid the escalator's basis to pipeline? Bao Wei, deputy director of the Municipal Management Center of Xuhui District, made an analogy, "If one foot can't put one foot, then tiptoe." The construction party sets the foundation to an inverted trapezoid, so that it can not only find the "lower foot" space between the pipeline, but also avoid affecting the water and gas pipelines on both sides.

The reporter noticed that there was no elevator installed in the southeast of the Southeast Bridge of Zhaojiabang Road, but instead set up an oblique lifting platform to provide services for special groups. "The distance between the ladder section and the building here is only 2.14 meters. After installing the escalator, the distance is reduced to more than 1 meter, which does not meet the relevant design specifications." The relevant departments of the district have considered the form of a staircase and a escalator. The existing pipelines must be moved away, and after the ladder section is built, the pipeline below cannot be repaired. Under the hindrance of multiple humps, the oblique lifting platform is finally selected. The staff will arrange the staff on duty every day. Citizens can call them if they need it.

The solution of common problems

The pedestrian bridge plus ladder belongs to new things. When the 38 flying bridge is installed and advanced, there are some common problems behind it.

For example, the approval process. Below the bridge is distributed with pipelines such as electricity, gas, water supply, communication, public security, and troops. As a special equipment, elevators also need to pass supervision and inspection. A project involves so many departments. If each one has to go around, will the gradient process be affected?

In July last year, Shanghai released the "Guidance Opinions on the Converted Elevators and Cabinary Environmental Reconstruction of the Bridge of Road People", which gave these questions about the answers. The "Guidance Opinions" clarified the leadership of the ladder and the responsibilities of the cooperative implementation of the department, and gave targeted guidance for the approval of each link.

At the same time, the Municipal Transportation Commission has intensified research on the technical and management requirements of the flyover of the bridge. Last year, the "Powerful Bridge Installed Elevator Guide (Trial)" was released simultaneously. This is the country's first guidance document for the installation of the elevator industry for the pedestrian bridge. Under the concept of barrier -free travel, it has made clear and detailed guidance on elevator venue selection, steps, wheelchair slopes, slopes armrests, and blind roads. "Under the breakthrough of the policy, the approval process of each link is simplified, and the number of hearts is more in the heart, so as to accelerate the construction." Bao Wei said. In terms of humanized design, in addition to barrier -free facilities, some elevators also have "careful machines". Yan'an Road Tibet Road Field Bridge, by imitating the stone texture and separation form of the large world building, echo the proportion of the facade of the large world building in terms of texture; Chongqing South Road Tianqiao has designed vertical greening and lighting of magnolia patterns. At night, the shadow of Magnolia is projected on the surrounding lawn, which not only illuminates pedestrians, but also feels like "shower".

"We are trying to promote the implementation of the project by increasing the investment of machinery and personnel. It is planned to complete the debugging and operation of the seven cities at the end of November. At present, except for the Tianqiao Bridge of Dongfang Road, the Tianqiao Bridge of Chongqing South Road, Zhaojiabang Road Wanping Road Tianqiao, Beizhai Road Union and the Tianqiao, the city has been completed. The city has started 32 flyover, and the construction tasks have been completed within the year.
