According to the City Meteorological Bureau, the rainfall is a typical Mongolia eastward moving vortex process which is affected by the common cold and warm air. It reaches Beijing under the northern pressure and combined with cold air.

However, the occurrence of such heavy rainfall is not unusual. In previous years, such intensity of rainfall occurred.

Metro lines are delayed.

Affected by heavy rain, yesterday afternoon, part of the subway line 1, line 13, Yizhuang line was suspended.

Answer

Flood control for urban rivers, lakes and North-South flood diversion

Yesterday, the head of the Beijing flood control office said that the rainfall was too large yesterday, exceeding the carrying capacity of the urban road, resulting in stagnant water.

It is understood that after yesterday's rain, all pumps in Beijing are open for drainage.

At 4 o'clock yesterday afternoon, the urban area began to rain, and the rainfall in some areas was relatively large.

In addition, according to the overall urban planning of Beijing, the principle of flood control in Beijing is determined to be "West storage east row, north-south flood diversion".

The purpose is to control floods in the Western Piedmont, to eliminate rain in the urban area and to reduce the disaster caused by floods.

Yesterday, urban rivers and lakes were launched simultaneously.

The city flood control office said it was relatively rare in recent years.

North flood diversion, that is, through the Anyang River sluice to the west side of the water row to the Qing River; South flood diversion, is through the right gate of the gate of the water drained to the cold water river.

At the same time, the road protection department of Beijing gathered at 15 o'clock yesterday for emergency disposal, and all the rescue teams were also on duty.

For today's weather, the city flood control office said that after a consultation with the meteorological department, it is expected that there will be a shower today, but a large amount of rainfall has basically ended in the first half of yesterday.

scene

The deputy mayor took command of the water.

At 7 o'clock last night, the headquarters of the 13 floor of Beijing flood control office was brightly lit.

Xia Zhanyi, vice mayor of Beijing and responsible person of Beijing flood control office and so on, 20 people sitting in the office, facing the rain charts and radar charts on the large screen, discussed countermeasures and commanded the front line.

"This is the first heavy rainstorm this year, so it's easier to block up.

In fact, the first rain every year is easy to plug, because there may be some leaves and so on, which will block the sewer.

One staff member said.

"That should be processed in advance."

Shouted Xia Zheng Yi.

He said that the staff must fulfill their duties and should be in the front line.

"I was surprised that the leaves would jam the pipes. Why did no one look at the leaves?"

Xia Zhanyi stood up, speaking.

It is understood that the executive vice mayor of Jilin in the city emergency office, vice mayor Gou Zhongwen in the city traffic control bureau command.

[Traffic Control Bureau]

The Municipal Public Security Bureau has launched the first step to strengthen the attendance plan, and the traffic police and the co management personnel in the city have been walking in the rain to dredge the traffic.

At the same time, outdoor display large screen and traffic broadcasting continuously broadcast the latest road information, and guide the vehicle to bypass the road with less traffic pressure.

[bus group]

The emergency plan for rainy days was started quickly, and more than 4000 safe operation professionals went deep into the line of waterlogging, and inspected the traffic to guide the traffic.

At 17, 300 additional vehicles were added to the late peak operation.

There are 10 bus lines to increase pport capacity and ease subway operation pressure.

[drainage group]

We should start early warning of flood prevention and respond to flood control and control, and require flood prevention personnel to strengthen the inspection of the rainwater outlets of the Beijing Ring Road and key areas, and all the support groups should be assembled to ensure the safety of the urban areas.

16, in response to the blue warning information released by the city flood control office, the first level response was launched.

Questioning

1 before the rainfall, the relevant departments have warned that it is going to rain heavily. Why is Beijing still flooded in large areas?

Why is the forecast in advance still flooded?

City Flood Control Office: large rainfall, heavy rainfall, long time.

The city flood control office said that serious water is not a problem that can be solved if there is preparation.

Yesterday's large rainfall, heavy rainfall, long rainfall time, these are the causes of water accumulation.

From the design point of view, urban roads can often cope with floods in 1 to 3 years, that is to say, when rainfall reaches 36 to 45 mm / h, it can drain smoothly.

Yesterday's rainfall has exceeded 100 years' standard in some areas.

From the overall perspective, the area with rainfall of 50 mm / h reaches more than 300 square kilometers, and rainfall reaches 100 square millimeters or more, reaching a total area of nearly 40 square kilometers.

This is also the main reason why a lot of water can not be eliminated in time.

2 previously, the flood control and drought relief headquarters said that 49 additional water points in the city had been formulated, and the departments concerned took measures to increase the pumping stations, build new drainage pipes and increase the rainwater estuary, so as to tailor the emergency plan for each water accumulation point. As long as the depth of the water exceeded 20 cm, the rescue personnel would take the water away within 20 minutes. Why is it still flooded?

Why is the "custom" plan invalid?

City Flood Control Office: the volume of water is too strong, and the capacity of drainage pipeline is limited.

The city flood control office said that the relevant pumping stations had been fully opened and flooded because of too much rainfall and too much water.

The capacity of the drainage pipeline is limited. Under the condition of excessive rainfall, natural discharge is not enough.

The person in charge, for example, said that when the movie was dispersed, all the people went to an exit and naturally walked slowly and queued up.

3 a livable city, when formulating a plan, should adhere to the infrastructure in advance and increase the construction of urban pipelines, such as roads, water, electricity, drainage and gas, so as to prevent the drawbacks of neglecting the construction of underground drainage systems.

A healthy developing city should also be a system of flesh and blood. An advanced rainwater storage system is the basis for ensuring the smooth flow of the city. To a certain extent, judging the development and livability of a city depends on its sewer level.

Under the existing conditions, will Beijing face the current situation of rainy and flooded and unable to change?

When will the pipeline network be put in place?

City Flood Control Office: flood season this year to clean up 49 water points again

The city flood control office said that for the existing pipeline network in Beijing City, if the pumping station is fully opened, its carrying capacity will be 50 millimeters per hour, which will not affect the traffic, but only cause shallow water in some areas.

Once the rainfall exceeds 50 millimeters per hour, there will be some plugging points.

The responsible person said that there were natural causes and human factors in the formation of blocking points.

Excessive rainfall, limited pipeline and traffic accidents will create an existing situation.

The responsible person said that Beijing has confirmed that this year for the flood season to clean up 49 water points, including Cui Wei area, Yuquanlu Road subway mouth and so on.

The standard of water treatment points released previously showed that the main roads could withstand the rainfall reaching 50 millimeters / hour. The construction measures were not allowed to cause any further water accumulation to ensure smooth drainage.
