假山建造2（Rockery construction 2） 1.1 rockery construction (1) positioning and laying of rockery; 1, review drawings First of all to understand the intention of rockery engineering design work, structure form and foundation of the master mountain, in order to correct lofting. Secondly, in order to facilitate the layout, according to a certain proportion in the plan, according to the project size or complexity of the layout, draw the grid size of 2m * 2m or 5m * 5m or 10m * 10m, with its square foot and intersection contour as the ground for lofting. 2, indeed lofting In the design grid online, choose a reliable ground and fixed point of reference, as the lofting point, then this point, according to the actual size of draw grid on the ground; and to be checked and the drawing of contour line position, released on the ground the corresponding gray contour. In order to facilitate the construction of foundation and earth, should not affect the pile and construction scope, select relevant parts easy to check the size of foundation, such as both vertical and horizontal center line, the rockery transverse direction and boundary line, the main parts of the control line position, set up in Longmen or buried pile stakes for lofting the white line to dig or when construction is being dug up, as a measure of the size or layout of the basis points again. (two) basic construction; The construction of the foundation should be carried out according to the requirements of the setting. The rockery foundation has shallow foundation, deep foundation and pile foundation. 1, shallow foundation construction The shallow foundation construction procedure is: the original soil ramming, the laying cushion, the masonry foundation. Shallow foundation is usually the foundation laid on the ground by tamping. This thing should be based will choose the ground leveling, remove the high ridge, fill the pits, and then compacted, spreading cushion and foundation. The quality of the infrastructure is strict
