Information

武汉Wuhan Jingwu Road blasted 7 residential buildings today精武路今日爆破7栋住宅楼

 

Pictured: The building below the black net will be taken by the blasting reporter Zhu Xiyong today.

 

  Chutian Metropolis Daily reported that Wuhan Blasting Company announced yesterday that at 3 pm today, the Jingwu Road area of ​​Hankou will demolish 7 residential buildings in one time, with a construction area of ​​40,000 square meters, which is the largest number of one-time detonated buildings in Hubei. The largest group of buildings was demolished and blasted.

 

  Yesterday morning, the reporter visited the blasting site of Jingwu Road area in advance, and asked Luo Qijun, the head of Wuhan Blasting Company, to explain the plan and difficulties of “Chutian First Explosion”.

 

  Blasting 7 residential buildings is expected to take more than 10 seconds

 

  The reporter entered Jingwu Road from Jiefang Avenue yesterday. In the middle section of Jingwu Road, the reporter saw several buildings with black protective nets, and several buildings surrounded by bamboo rafts and bamboo raft walls. The top of the building hangs the red of Wuhan blasting company. Banner, armed police soldiers stand outside the buildings. "The buildings you see are the buildings to be demolished tomorrow afternoon. There are a total of seven buildings. Now our engineers and technicians are connecting the blasting network in the building. It is expected that the 7 buildings will be laid down in more than 10 seconds. Luo Qijun introduced.

 

  The 7 buildings are distributed within a radius of 150 meters, 5 buildings are 8 floors, and the other 2 buildings are 9 floors, all built in the 1980s and 1990s.

 

  According to statistics, this blasting drilled 15,000 blastholes, using 18,000 detonating tubes and 480 kg of explosives. There have been many large-scale blastings in Wuhan history. For example, Yongqing tablets have been demolished in six buildings by one-time blasting, and today's blasting will demolish 7 buildings in one time, so it is called “Chutian First Explosion”.

 

  There are many buildings to be demolished in the Jingwu area. Blasting is only one of the demolition methods, mainly for buildings of 8 floors and above, and for buildings below 8 floors.

 

  The blasting methods vary from 7 buildings to different structures.

 

  Luo Qijun said that due to the various types of structures in the seven buildings, the environment in which they are located is not the same, and the blasting methods adopted by the blasting companies are also different.

 

  The distance between the 1# building and the 2# building is only 10 centimeters, and the blasting company decided to let them collapse back. There is a row of bungalows 21 meters away from the south side of the 1# building. It is a car repair factory and is still in production. In order not to affect the car repair and distribution plant, the blasting company adopted a time-delay blasting technique from the east to the west for the 1# floor, which can reduce the front impact distance.

 

  The 2# building is a “cross-shaped” structure with a 9-storey building, which is the biggest difficulty in this blasting. In addition to the explosive detonators installed on the 1st to 3rd floors, the blasting company also installed explosive detonators on the 6th floor, and the blasting area is one more layer than the general building.

 

  The 3# building adopts a vertical to south-by-span delay collapse technique.

 

  The 4# building and the 5# building are only 1.5 meters apart. The blasting company decided to let the 4# building collapse to the west and the 5# building collapsed to the south.

 

  The 6# building and the 7# building are all “one-shaped” single-family buildings, and the blasting difficulty is relatively small. The former is oriented to collapse westward, and the latter is oriented to collapse southward.

 

  300 giant water bags dust-proof protective net anti-splash

 

  Such a large-scale blasting will inevitably generate a large amount of dust, and how should the blasting party respond?

 

  Luo Qijun introduced that one week before the blasting, people were arranged to use the water in the fire hydrant to flush the dust and dregs in the building to minimize the amount of dust generated. In order to prevent dust during the blasting process, the blasting company purchased more than 300 giant water bags and placed them in each blasting floor. Each water bag is 8 meters long and 1 meter in diameter and can hold 5 cubic meters of water. Some floors have 20 water bags. However, since there are only 2 fire hydrants at the blasting site, water bags cannot be placed on some floors. "Although some measures have been taken to reduce dust, it is difficult to completely eliminate the dust on the site. This is also to please the public." Luo Qijun said.

 

  In order to prevent spatters from blasting, people are installed with protective nets or bamboo trusses and bamboo fence walls. Since the blasting has basically no impact on the roads such as Jiefang Avenue, Xinhua Road and Jianghan North Road, traffic control will not be implemented during the above road blasting.

 

  Special person escorting blasting equipment, armed police soldiers guarding the building

 

  The amount of explosives and detonators used in this blasting is very large. How are these blasting equipment delivered to the scene?

 

  Luo Qijun said that in order to use blasting equipment, the blasting company must first report the blasting plan to the public security department. The public security department organizes experts to demonstrate the plan. If feasible, the blasting company will declare the dosage and deliver it to the site by a special civil explosive company.

 

  The blasting equipment required for this blasting was sent from Jiangxia District. The civil explosion company distributes by day, that is, the daily delivery amount is the amount required for the construction of the blasting company on the same day. If it is not finished, it must be returned to the Jiangxia warehouse on the same day.

 

  Jiangxia started loading at 4 am every day, and at 6 o'clock in the morning, it was able to go to Jingwu Road. Originally, the public security organs limited the speed of vehicles transporting blasting equipment to no more than 40 km / h, and must take the designated line, and maintain a certain safe distance from the vehicles before and after. Explosives and detonators are packed in 2 containers with a 1 meter gap in between.

 

  The blasting began with the installation of explosives at 2 pm on the 19th. From that moment on, the armed police soldiers guarded the seven buildings in the proposed blasting, prohibiting unrelated personnel from approaching the building to ensure safety.

 

  Jingwu Road, Phoenix Nirvana will become a high-end business district

 

  The reporter learned from the relevant parties in Wuhan yesterday that after the demolition of the Jingwu Road area, it will transform into a high-end business district, and at the same time encrypt the regional road network to facilitate the citizens to travel.

 

  The Jingwu Road area has a total area of ​​20 hectares. According to preliminary assumptions, the area will be dominated by commercial, office, hotel and residential functions, and will be built with characteristic commercial streets. Jingwu Road used to be a street in the duck neck. The brand is very loud, but the business grade is lower. The proposed commercial street is initially considered to continue the brand of the duck neck street in the past, but will not engage in low-end formats such as workshop production and road economy. How to build it specifically will be determined in conjunction with the investment situation.

 

  Taking advantage of the transformation of Jingwu Road, Wuhan will also encrypt the road network: at least one road will be added to the east-west direction, parallel to Jiefang Avenue, connecting Xinhua Road and Jianghan North Road; north-south reconstruction and new roads, Jingwu Road will be Widening the transformation.

 

  The district will also set up a small green square to enhance the landscape image and improve the working and living environment of the citizens.
