Before the construction of plastic rockery is started, a series of preparatory work should be done to ensure the smooth construction of the project. The construction preparation mainly includes: design drawings bottom, village material preparation, site preparation, staff preparation and other work.
The construction of rockery is a landscape engineering activity with obvious characteristics of artistic creation. In a large rockery, one hand to the image and the size of the relationship line and control point each time according to the design of rockery elevation map, on the other hand to consider the local topography and cultural customs and other characteristics, has been created in the modeling and technical details, the development of.
At present, there is no official calculation method for the rockery project, and it is mainly based on many years of experience based on the professional rockery construction party. The effect of the rockery is different, the shape is different and the height is different, which all affect the quantity of the project. Because there are too many change factors in the rockery project, it is difficult to calculate the quantity of the project accurately.
The main material of plastic rockery stone for iron, steel, steel, steel wire, cement, sand, etc.. To choose the material according to the specific requirements of the rockery design drawings specifications. For large plastic stone rockery, usually in the angle selection are based on 5*5 or 4*4 to 3*3 angle, angle to horizontal and vertical auxiliary link.
At present, the cement is usually mainly 325 cement, the characteristic is that the cement made by the cement is not easy to crack. Sand is generally the first time plastering with fine sand, second times to wash sand as good. The approximate proportion of cement and sand is 1:2.
