June is the "safety production month." The theme of this year is "strengthening the awareness of the red line and promoting safe development." In order to enhance the company's production safety, awareness of civilized construction, and improve safety management level, yesterday afternoon, Shenzhen Construction Safety Supervision Station and Shenzhen Construction Association sponsored the “Safety Production, Civilized Construction, and Excellent Demonstration Site” on-site observation and exchange activities will be selected in CSCEC. Bureau One Company South China Company Shenzhen Branch has undertaken the construction of the Aerospace Science & Technology Plaza Project Department. More than 1,800 people from the city’s construction companies, supervision units, construction unit project leaders, safety production managers, safety officers, safety officers, and labor management personnel attended the conference.

The space technology plaza project is located at the intersection of Haide Sandao and Houhaibin Road in Nanshan District. It consists of two super high-rise office buildings, a six-story podium, and a four-story basement. The project occupies an area of ​​12,000 square meters, the building area is 196,000 square meters, and the building height is 241.7 meters. The engineering structural system is a hybrid frame + reinforced concrete core barrel system. The pile foundation is a punched (drilled) bored pile foundation, and the engineering uses a large number of steel bones. Columns and steel frame beams, steel structure usage amounted to 12,000 tons. The project was invested and developed by Shenzhen Aerospace High-tech Investment Management Co., Ltd. and the first construction engineering company of China Construction Third Bureau was built. The main functions of engineering buildings include shopping malls, commercial offices, underground parking lots, and public squares. After completion, it will serve as China Aerospace Science and Technology Group's operation and management center, research and development center, and international cooperation and exchange center in southern China, and will be another landmark project in Shenzhen.

Live experience

"Danger" is actually around

Everyone grew up receiving education in safety knowledge. However, many people may panic when real dangers are encountered. At the scene of yesterday’s demonstrations, many live experience sessions were added. This is a unique point of comparison with the previous ones.

How to prevent falling from high altitude? What posture should be maintained when the sky crashes? The project specifically built a high-altitude crash experience platform. Yesterday, the reporter also experienced a hand. The reporter went to the designated location on the second floor under the guidance of the staff: a 80-cm square area. When one thinks of a switch, it is necessary to "fall" from here. The reporter is very nervous. The staff asked reporters to hold their hands behind their heads. They had not yet waited for the reporters to return to God. When the “flooring” was heard, the floor of the reporter’s foot was “broken” and instantly lost weight. Fortunately, all the floors were covered with thick sponges. The staff member told reporters that in order to prevent the height from falling, the individual should hold the back of the head with both hands. However, the reporter remembered the "falling" posture. Since he lost weight, he released his hands with reflexes, and he was confused.

In the on-site experience there is also a crash experience with a helmet. Safety helmets are necessary safety measures for workers entering construction sites. If you don’t wear a helmet, what will happen? This experience is very vivid. The reporter also experienced a time, wearing a hardhat and standing in a designated cabinet. As the staff member hits the bell, a piece of iron, similar to an egg, will be picked up from the top of his head and it will produce a loud sound. The reporter took a closer look. The iron is not big. It is only half a meter from the head. There will be such a loud noise. If the helmet is not worn, the head will be bleeding at that time and even have more serious consequences. The on-site staff told the reporter that it is through these visually intuitive experiences that everyone really feels that safety production is indiscreet. Safety production must begin with the system, and workers must consciously form habits.

The fire extinguisher drill experience, integrated power experience, balance beam experience, heavy load handling experience, mobile operating platform experience, tower crane lifting, wire rope experience, and seatbelt use experience are also on site.

Civilization Construction

Every move shows standardized management

As the saying goes, amateurs look busy and insiders look at the door. At the live observation meeting on June 10, more than 1,800 people were elites and experts in the construction industry. Once you enter the safe passage, you will see a neat and orderly safety standardization atlas, rich and interesting safety comic propaganda, safety warning signs everywhere, neat and clean construction sites, comfortable and healthful workers' rest areas, and pavilions. Standard and standard shelters, neatly stacked materials, complete construction equipment with safety facilities, and standard guarding at the entrances to the sidelines are all well received by visitors.

In the observing channel, there is a BIM (Building Information Modeling, BIM, Building Information Modeling) experience area with four 60-inch LED computer screens. Observers can directly touch and click to understand the frame structure and schematics of the entire space science and technology plaza project. Including civil engineering, steel structure, electromechanical installation, curtain wall, air defense and decoration.

There is also a brand exhibition area, which includes the construction of some brand projects of the Southern Region by the Shenzhen Branch of the China Construction Third Bureau and the construction of the Shenzhen South Branch of the China Construction Third Bureau, the construction of the Aerospace Science and Technology Plaza by the Shenzhen Branch of the China Construction Third Bureau, and a project office area. China Construction Third Bureau, a corporate safety management standard atlas, project safety production month campaign comics.

In addition, a standardized safety atlas was set up on the site, and labor insurance shoes, non-slip shoes, flame-retardant mesh safety nets, firefighters' dress display, main distribution cabinets, distribution boxes, and safety helmets were displayed in physical form. , equipment switch box, standardized guardrail, cart type fire extinguisher, shoulder harness, welding protective gloves, cart type fire extinguisher, electric welding cart, welding goggles, fire extinguisher, fire hydrant, electrician inspection tool, emergency lighting fixture , Oxygen acetylene carts, fire hydrants, electrical testing tools and operators to dress and so on.

Technology excellence

Hard to ensure quality

During the construction process, a company in the China Construction Third Bureau used a large number of new technologies to overcome various technical difficulties and successfully completed its engineering construction tasks. During the construction period, we paid attention not only to project quality, but also to safe production and civilized construction. In February 2014, we successfully obtained the “Shuangyou” site in Guangdong Province and “AA-grade site in Guangdong Province”. Song Chengyu, head of the project, told reporters that the quality of the project was positioned as a Grade A office building of 5A and the project quality target was positioned as the “Luban Award”.

Song Chengji told reporters that this project has several major features: First, the project is large in volume and unique in shape; the first floor lobby of the 1# tower of this project is up to 30 meters high, and a height of 12.9 meters is set on the east side of 43th to 45th floors. In the upper garden, over 46 floors use an outrigger truss to hang the upper structure upside down. The middle of the sky garden is set to one-step spiral staircase, leading from 43 floors to 45 floors. It involves a large number of equipment, pipelines, elevators, curtain walls, etc. The structure is complex, with large volumes and unique shapes. Second, the project belongs to the construction of super-long and large-diameter engineering piles in the coastal area. The project rushed (drilled) bored piles, the longest pile length of up to 105 meters, the maximum diameter of 2.6 meters, and is located in the coastal areas, groundwater level High, located in the fault zone, with uneven weathering, a large amount of kaolin, and melting with water, the construction is extremely difficult. In the construction, the most advanced domestic rotary drilling rig and rotary drilling machine were introduced. The super-long steel casing with a length of 15 meters was used and good results were obtained.

The reporter learned that the project uses the standard Bayley rack-mounted smart lift mould system independently developed by the China Construction Third Bureau and the company (abbreviated as the top mold technology). The system consists of a power control system, a steel platform system, a support system, a pylon protection system, and a formwork system. Among them, the steel platform system is assembled with 200-type high-shear berets, which is simple in structure, easy to install, large in load, and good in interchangeability. It is suitable for assembly of any top die system steel platform, and can be reused many times. . The template system adopts aluminum alloy formwork, which is light in weight and easy to install. Through the wall corner template, the wall section change can be adjusted, and the size and perception of the concrete can be well ensured, which can be repeatedly used. The power system adopts an intelligent hydraulic control system, which can achieve automatic leveling in the lifting process and improve the accuracy and safety of the entire top mold system. The rack system adopts the aluminum rack protection system. Under the premise of satisfying the strength and safety requirements, it also realizes the adjustable rack, light weight, easy installation and repeated use.
