Background

The development and utilization of water resources are the process of continuous sublimation in the human progress process.

The largest area of water surface utilization to date is the shipping industry, which requires large water surfaces and long rivers, where the greatest property of water is flexibility. In the past, human society has basically "sighed water" in addition to the cultivation of aquatic animals, because no supporting point for force can be found in flexible water. In the past, piling in water to fix objects on the water surface is a common method for a long time, but because the stress of the top point of the pile is directly transmitted to the stress point of the pile and the water bottom layer, the pile foundation is easy to be inclined.

In recent years, with the rapid development of economy in China, the discharge amount of various sewage is greatly increased, and a large amount of wastewater is directly discharged to a water body without being treated and exceeds the self-purification limit of the water body. Thereby causing imbalance of oxygen supply and oxygen consumption of the water body, leading the water body to be in an anoxic or even anaerobic state and causing the phenomena of fishy smell and eutrophication of the water body. This can cause the whole ecosystem to be in crisis, seriously affect the ecological environment and also cause great influence to the life of residents. Therefore, people are more and more concerned about the living environment, particularly the water environment quality and the water natural landscape situation, the method for carrying out water ecological restoration by planting plants by the float method on the water surface is high in economic benefit, free of pollution and capable of bringing other economic benefits, multiple purposes are achieved, and the method is an excellent water ecological restoration means, but various facilities for carrying out water ecological restoration by the float planting on the water surface are finally blown away by wind due to the fact that no reasonable and practical fixing method is available. A method for exploring water surface fixation is in progress, for example, a utility model patent with publication number CN211620082U discloses a rotary combined ecological floating island, which includes a central shaft with one end fixed at the bottom of the water and the other end extending out of the water surface, and a floating island body connected with the central shaft and capable of rotating around the central shaft under the action of natural power, wherein, the patent document describes that the central shaft is composed of a fixed column and a circular ring sleeved on the fixed column, but when the central shaft of this form is actually used, when the circular ring receives an external acting force from the side direction, the circular ring can directly act on the upper end part of the fixed column, thereby causing the fixed column to deviate, further affecting the lower end stability of the fixed column, and even causing the whole system to have a structural damage problem due to losing balance. The fixing of the water surface object solves two problems of the vertical stress supporting point and the lateral stress balance of water at the same time, so that a stress balance device which ensures the more stable operation of equipment for water surface production or living activities is needed.
