Background
The large-scale unit, the super-long blade and the high tower height become the development direction recognized in the industry. With the increase of the capacity of a single machine, the running radius of the blade is increased, and the height of the tower is continuously increased, so that the steel-concrete tower is rapidly popularized in a high tower era. The steel-concrete tower is a prestressed reinforced concrete structure, the prestressed structure is accompanied with the tensioning of a prestressed system, and the tensioning end of the steel-concrete tower is almost arranged at the bottom end of the tower, namely the foundation side. Based on the structural arrangement and the construction process, the steel-concrete tower foundation adopts a hollow foundation form.
The hollow part of the hollow foundation at the present stage is an annular basement, which is limited by the problems of an upper structure and manufacturing cost, the basement space is relatively narrow, and the following two objective problems generally exist:
1. because the site environment of unit infrastructure is relatively poor, mostly build by river crossing embankment. Although the design and construction of the unit foundation adopt corresponding waterproof and anti-seepage measures for the foundation, the micro cracks in the concrete structure exist forever. Under the condition of abundant water systems, the phenomena of water seepage and water leakage in the basic cavity in the service period occur. A water collecting pit is usually designed at the center of a bottom plate of the foundation, and accumulated water is discharged by adopting a movable pumping device during operation and maintenance of the unit.
2. In the process of prestress construction, heavy construction equipment needs to be transported in and out in a narrow space, and the process occupies a large amount of working hours in the current flow construction, so that the construction period is delayed.
According to the structural stress characteristic of the steel-concrete tower and the technical requirement on the prestressed tension side of the foundation. If the problem of water seepage and water leakage in the underground chamber can be solved on the one hand under the condition that the force transmission path of the whole structure and the limitation of the prestress tensioning side are not changed, on the other hand, in the prestress construction process, heavy construction equipment does not need to be transported in and out, and the construction period in the process is shortened. Such a foundation structure would be a significant gain in reducing maintenance costs during service and reducing construction costs at the construction stage.
