What are the difficulties to improve the quality of fountain construction

With the continuous acceleration of the process of urban modernization, more and more hydrological landscapes are widely popularized and applied, which naturally includes the special landscape sketch of fountain waterscape. The construction of the fountain waterscape project has undoubtedly brought people a richer visual and auditory enjoyment, but there are also many difficulties in the fountain construction process. In order to promote the further improvement of the fountain construction quality, our company is now focusing on the existing fountain construction. A brief analysis of the difficult problems and corresponding solutions are proposed.
1. Selection of pump form
At present, many fountain construction projects will use submersible pumps to improve water conservancy during construction. Submersible pumps do not require a pump house, which can reduce the cost of the project to a certain extent and reduce the construction area. However, compared with centrifugal pumps, the reliability of submersible pumps is much lower, and submersible pumps often have a situation where one submersible pump damages the others. The possible consequences are: the crystal may have partial defects, which will affect its overall viewing effect; if the insulation equipment of the water pump is damaged, it may make the water conductive and cause the danger of electric shock. In the process of garden construction, how to develop highly reliable submersible pumps has become one of the research topics of modern garden construction. This is also the key to reducing the cost of fountain waterscape projects. In view of the more obvious advantages of centrifugal pumps than submersible pumps, fountain construction companies should choose centrifugal pumps for waterscapes that need to be kept running for a long time when they are constructing gardens.
2. Water level control
Water level control is an extremely important part in the control of waterscape water level. Nowadays, common garden designs use jet-suction nozzles such as cedar-shaped sprinklers or gushing springs, all of which are very sensitive to changes in water level. A little rise and fall of the water level will seriously affect the changes in the height of the fountain and the shape of the water outlet. Therefore, the use of reliable automatic water replenishment devices and overflow pipes is indispensable. At present, the fountain construction company has developed a better way to use an independent water level balance tank or a hydraulic water level control valve, and use a very long diameter The connecting pipe connects the water feature pool. If it is placed outdoors, it should camouflage the water level balance device, such as making its shape into a large tree root or a fake rock mountain. In the north, winter freezing should also be considered. The overflow pipeline should be set in the water level balance well. Since the balance well is usually covered with a top cover, it can also shield the overflow and water supply noise.
3. How to choose piping materials for waterscape engineering?
In the previous garden construction, the pipe material used by the fountain construction company was mostly hot-dip galvanized steel pipe. After this kind of steel pipe was used for a period of time, its surface was easily corroded by rainwater, dust and some acidic substances in the air, which would reduce The water landscape is beautiful, and the life of hot-dip galvanized steel pipe is generally very short. If you use better materials such as copper pipes or stainless steel pipes, the price is more expensive, so in order to reduce the cost and solve the above problems, people propose to use UPVC pipes. This kind of pipe can prevent the surface of the landscape from being corroded, but its weather resistance and heat resistance are relatively poor. If the sunlight is direct, the pipe will quickly age. In the hydrological landscape design, the fountain construction company can use UPAC pipes at the bottom of the pool, which is not visible to light, and use copper or stainless steel pipes for the part exposed to the sun, which greatly reduces the cost.

Of course, in addition to the selection of water pump form, water level control, and waterscape engineering pipeline material selection, there are also several difficult issues that need to be solved urgently, such as the control of water source and water quality, the selection of lighting, and electrical construction during the construction of the fountain. , Due to space limitations, I will not repeat them here.
