Why do dry pile foundation hangers like this equipment?

Recently, Zhao Kui, the owner of Zhengzhou Shujie Loading and Unloading Service Co., Ltd., encountered a problem.

Zhao Kui said: "We dispatched three truck cranes to cooperate in the Chinese People's Insurance Building project in Zhengdong New DistrictRotary drilling rigsComplete the rebar cage under the cage. In the early stage, in order to let the truck crane enter the site, an excavator was used to repair the road and lay steel plate sleepers, which consumed a lot of manpower and time costs. ”

"After the equipment finally entered the site, the rotary drilling drill can become many holes a day, and these truck cranes have to be displaced and hit the legs one after another. As the project process gradually accelerates, the construction node is getting closer and closer, and according to the current progress of the operation, it is difficult to complete the task. ”

Just when Zhao Kui was very distressed, he saw an article in the circle of friends. According to the article, a construction site in Shenzhen is using a telescopic crawler crane with rotary drilling drills, and the efficiency has been significantly improved. So, Zhao Kui took the initiative to find out, and with the mentality of trying it out, he purchased a STB300T5-6 and immediately put it into the project.

After entering the STB300T5-6, in the face of the harsh construction environment, the advantages were fully revealed. It comes standard with four wheels, and it can still be hoisted at an inclination of 4°, so you don't have to spend energy leveling the road. There is no pressure to walk with load on the muddy road, after the rotary drilling drill completes the drilling, it then lifts the reinforcement cage to the orifice, and puts it into the hole to end the cage, a set of actions in one go, and the construction efficiency is greatly improved.

Zhao Kui said: "After this telescopic boom entered the site, I withdrew two truck cranes and came back, leaving only one truck crane on site to cooperate with the operation. Although the equipment has been reduced, there is no need to repair roads or wait for the truck to crane the outriggers, so the construction efficiency has not become lower, and it has been increased by at least half. One telescopic boom can be operated at least with two rotary digging at the same time, and the construction party is very recognized. The two truck cranes I withdrew can go to other jobs, killing two birds with one stone, and the income is directly doubled. ”

At present, the vast majority of foundation construction sites in Zhengzhou are still dominated by traditional construction methods, first using one or more excavators to transfer the reinforcement cage, and then using a truck crane with rotary drilling drill to lift into the hole. However, the disadvantages of traditional construction methods are obvious, and if it rains, the truck crane will be more difficult to walk. Therefore, it is imperative to change the exercises.

Wang Ning, a security inspector of the People's Insurance Building Project in Haoding Zhengdong New District, China Construction Seventh Engineering Bureau Co., Ltd., said: "In Zhengzhou, I have only heard of the telescopic crawler crane before, but I have not really seen the telescopic crawler crane, and I know that its construction efficiency can be, but I didn't expect it to be able to withstand two truck cranes." The efficiency has been improved so much, our construction period has also been guaranteed, and then there is the work of foundation construction, I must be the first to think of Zhengzhou Shujie. ”
