The leakage of the musical fountain is closely related to the use of different properties. The larger the cement particles, the smaller the surface area, the lower the activity, the smaller the shrinkage rate, the higher the heat of cremation. The shrinkage rate of Portland cement is lower than that of slag cement, fly ash cement, bauxite cement and quick-quenched cement, and the heat of cremation is lower than that of Portland cement. The shrinkage rate and mud content of sandstone increase. The larger the aggregate size, the smaller the sand rate, the smaller the shrinkage rate. The greater the water-cement ratio, the greater the shrinkage, the greater the reinforcement rate, the smaller the shrinkage rate. In most cases, ordinary Portland cement is widely used, but the effects of natural resources and environmental factors are replaced by other materials in different places, and leakage is caused to some extent.
1. The binding of formwork and steel bar is not in accordance with the requirements of technical specifications.
2, in order to facilitate construction, in the process of concrete pouring, concrete should be added to concrete, so as to improve the workability and fluidity of concrete. Collapse degree becomes stronger, viscosity is reduced, strength and impermeability is reduced, make concrete solidify and solidify seriously.
3, in the concrete pouring engineering, do not use vibrator vibration treatment of concrete, so that the concrete internal compactness is insufficient, resulting in a large number of honeycomb or hole shrinkage in the concrete back wall.
4. There are no eight bars on the side wall and bottom plate of the waterscape, resulting in stress concentration and instability.
5, waterscape equipment pipe and concrete contact position has not been appropriate vibration and compaction, easy to produce small cracks in the contact position.
The key to the formation of the style and shape of fountain equipment lies in the nozzle
From the form of sprinkler head to classification, it is mainly divided into single jet sprinkler head, spray sprinkler head, return to transition sprinkler head, annular sprinkler head and fan sprinkler head, these are more conventional sprinkler head is also a wide range of applications, such as porous sprinkler head, deformation sprinkler head, suction sprinkler head and so on. The principle of sprinkler head is very simple, the amount of water required by different specifications of sprinkler head will also produce differences, and the size of the pressure difference in the design to form water flow, and due to the different shape of the sprinkler head, the resulting spray will have their own characteristics.
Fountain control, now more commonly used three control methods, one is the hand valve control, this control method is manually operated, the use of manually controlled water valve to adjust the pressure in the water pipe, so as to form different strength of water flow. This form of control is relatively traditional, and requires tedious manpower, requiring staff to carry out accurate operation, so the application scope of this form has begun to narrow. Second, relay control. The main standard of this control is time. The relay can control the water flow and even the light through the artificial time setting, realizing the custom mode and freeing people’s hands. The third is sound control. The control of this fountain mainly uses sound control to operate. The equipment required is more rigorous from acoustic to electric converter to power equipment, so the investment cost will be more. But in the process of operation, such a control form can play more space and room, more suitable for some large music fountain performance. In the long run, in the process of fountain construction, businessmen should consider their own actual situation when choosing which control form. In addition, during the construction of a fountain, water drainage facilities is also a key ring, for a small nozzle of fountains, water quality request is higher, so you also need to add some filtering system, and in the choice of drainage material, also need to consider to the pool of material structure, waterproof material can prolong the service life of tank, the water erosion.
