Daily rack 8 日 Shrimp Ponds have long dragons on the beach

Qinglan Expressway (Shuangbu to River Setting Section) Reform and expansion project Pressing the "Fast Inlets" will become the first domestic long -life asphalt pavement highway

The sun is like a hot sun, the traffic beside you is rolling, and the heat under his feet strikes people. Standing on the empty construction venue on the horse, Dong Kai can't take the sweat beads. Kiss. Dong Kai is the chief engineer of the project department of Qinglan Road Bridge Construction Group Co., Ltd. Qinglan Expressway Shuangbu to River Set and Expansion. The project enters the field from the end of last year. At present, the project is setting up the speed of 8 榀 box beams on a daily average. A "flying dragon" was built on the beach of the shrimp pond.

Reinforced workers work at high temperature

Insure progress misalignment peak war high temperature

At about 3 pm on the 3rd, the reporter came to the construction site. Dong Kai told reporters that from 11 am to 3 pm, it was the rest time of workers. "During this time, the sun is the most exposed. In order to prevent heat stroke and ensure the health of workers, we implement peak construction to avoid high temperature periods." Although it was 3 pm, the construction site was still extremely hot, and the waves came up.

On the north side of the construction site, the current situation is Qinglan Expressway, and there is a wasteland on the south side. "The temperature is too high. Workers, especially welders, need to work on the steel bars. Sometimes the reinforced bars are hot and hot, and they must avoid high temperature periods." The reporter saw that workers who were doing welding operations for the pier for the pier were wearing long -term wearing long wearing workers, all wearing long -term wearing long -term welding operations. Sleeve clothes, wearing labor -friendly shoes on their feet, in order to prevent burns, wearing thick gloves on their hands. The workers stood on the reinforced bars, bent down, the head was scorching the head, and the feet were hot steel bars.

Dong Kai told reporters that since the construction, the project department has continuously optimized the construction plan to ensure the smooth development of the Qinglan highway reconstruction and expansion project. Pile and the first box beam. In order to ensure the safety and orderly construction of the first part of the pier pillar, build a model demonstration project, and organize all construction staff to learn the construction process and standard specifications before the construction to ensure that the construction meets the relevant requirements. During the construction process, each process strictly achieved technical intercourse, and at the same time clarified the responsibility of on -site personnel, controlled the construction process throughout the process, and ensured the smooth completion of the first pier pillar construction.

"Long Dragon" on the beach of the shrimp pond

In the upper horse section, the bridge pier rises from the ground, from the perspective of high altitude, as if a "long dragon" is lying on the ground. "This is the upper Matt Bridge. In addition to the bridge, we are also responsible for the construction of the Xiaojia Bridge." Dong Kai told reporters that the reason why the bridge is used to build a high speed in this section is mainly to consider the geological conditions of this section. The area where the Bridge is located is originally some shrimp pond beach coating, the foundation is soft, and the bridge construction plan can effectively avoid future foundation settlement. Each pier depth is about 8 meters. During the construction process, in order to ensure the operation of rotary drilling equipment, many steel plates were laid. The thick sludge layer is easy to flow. "In addition to everyone's naked reinforcement workers, there are many workers working inside the bridge pier. They are not surrounded by wind. Their" inflammation 'value is higher. "Dong Kai told reporters that there are 309 pile foundations in the 3 standard section of the 3th bid. Essence In order to grab the construction period, nearly 300 workers are working in the same requirements as required. Everyone is divided into multiple "assault teams", some are pouring bridges, and some are set up in box beams. At present, an average of 8 cricket beams are set up every day. These box beams have been prepared in advance, which can save work time more than pouring on the spot.

During the construction process, the project continued to innovate. Due to the amount of drilling slag generated by about 87,000 cubic meters, and the 70,000 cubic meters of soft soil dug out of soft base treatment, a total of 160,000 cubic meters of earth and stones will be generated. 10,000 yuan. During the field inspection, it was found that the height of the Dhehe river embankment near the construction road was short, and the flood disasters were very easy to occur due to the surge in the river, and it had a serious impact on the new road embankment. Through active communication, the project department has determined the use of the dug -of -drill dregs and earthwork to widen the Deliche embankment, and to complete the reinforcement work of the river embankment before the flood season, greatly reduce the soil and stone foreign transportation. The cost generated.

"Frequent rainfall has also brought us a severe test." Dong Kai told reporters that many rivers at the construction site are flood discharge rivers in nearby villages. In order to ensure the safety of the flood season, the project department has arranged a special person on duty and took measures according to the weather forecast in advance. , And equipped with strong pumping equipment.

At the end of the year, the first place in China is the first in China

The Qinglan Expressway Shuangbu to River Setting and Expansion Project is an important component of the comprehensive transportation system of Huanjiaozhou Bay in our city, and it is also a key channel for the Jiaodong International Airport to collect the sparse operation system. During the three -year tackling operation of urban renewal and urban construction in our city, the Qinglan Expressway Shuangu to River Setting Section Reconstruction and Expansion Project was included in Qingdao's traffic infrastructure construction three -year tackling operation "94521" project "94521" project Essence The project is invested and constructed by Qingdao Transportation Development Group, a subsidiary of Qingdao City Investment Group. The main line of the project is about 15.797 kilometers, and the two -way eight -lane highway standards are used for reconstruction and expansion. The design speed is 100 kilometers per hour. The main line of the project has a total of three interchange between Qianyang, Hongdao, and Anhe Road. Yuan. The main construction content is half widening in the south side. The implementation of the Qinglan Expressway is raised and transformed to meet the conditions for the roads of the surrounding community planning roads. Development and utilization, especially the development of south side beach, provides convenient transportation guarantee. According to the plan, the project will be completed on the left at the end of this year, and the first interpretation of the main line will be completed (then the right -handed construction is turned on), and the main body will be completed by the end of 2023. At that time, this highway will become the first domestic highway on long -life asphalt pavement, which will break through the technical standards of 15 years of design and use of traditional road structures. The design service life is 30 years. After the project is completed, it will be efficiently connected with the first phase of the new airport high -speed, new airport high -speed connection line, and Huanwan Avenue to effectively alleviate the "stuck neck" problem between Jiaodong International Airport and the main urban area, which greatly enhances the surrounding road network to solve the energy level. It is of great significance for promoting the development of Huanwan.
