4.1 Fixed point layout: According to the design requirements, the plastic stone rockery is positioned at fixed points. The grid method is used to determine the outer contour line and horizontal points of the mountain on site, and the excavation line of the foundation is set out along the contour line.

4.2 基础工程 山体基础多为砖基、砼基或钢砼基，浇筑基础前应按山 体的外轮廓线支模及配筋，严格控制山体基础的外形尺寸，以 免影响树木配置种植。浇筑时应埋好钢材主骨架的预埋铁件和 钢砼骨架柱的预留钢筋，并控制好柱间的间距和轴线位置。

4.2 Basic engineering: Most mountain foundations are made of brick, concrete, or steel concrete. Before pouring the foundation, formwork and reinforcement should be installed according to the outer contour of the mountain, and the external dimensions of the mountain foundation should be strictly controlled to avoid affecting the planting of trees. During pouring, the embedded iron parts of the steel main skeleton and the reserved steel bars of the steel concrete skeleton column should be buried, and the spacing and axis position between the columns should be controlled.

4.3 主体骨架 塑石假山的主体骨架一般为砖砌体和钢砼柱及钢型材骨

4.3 The main skeleton of the plastic stone rockery is generally composed of brick masonry, steel concrete columns, and steel profile bones

4.3.1砖砌体骨架 依照风格定位线在基础上弹出山体外轮廊线，按轮廊线 内砌筑墙体，砌体用砖需浇水湿润。用1:3 水泥砂浆砌筑， 砌筑密实度和粘结度应符合建筑砌体规范要求。立面按设计要 求进行局部外挑式内凹，幅度大的应设置钢筋以增加砌体的钢 性及稳固性。

4.3.1 The brick masonry skeleton should be positioned according to the style line, and the outer contour line of the mountain should be marked on the foundation. The wall should be built according to the contour line, and the bricks used for masonry should be watered and wetted. Use 1:3 cement mortar for masonry, and the compactness and adhesion of the masonry should meet the requirements of building masonry specifications. The facade shall be locally cantilevered and concave according to the design requirements, and steel bars shall be installed for larger areas to increase the rigidity and stability of the masonry.

4.3.2 钢型材骨架 山体中常用的钢型材骨架有槽钢和角钢，应根据山体造 型的体量大小和高低要求，定出每根钢柱的长度尺寸并编号， 按编号进行逐根焊接和横梁、挑梁的焊接，焊接质量应符合规 范要求，焊接施工完后应对整体骨架做防锈和防腐处理。

4.3.2 Steel Profile Skeleton The commonly used steel profile skeletons in the mountain include channel steel and angle steel. The length and size of each steel column should be determined and numbered according to the size and height requirements of the mountain shape. Welding and welding of beams and cantilever beams should be carried out one by one according to the number. The welding quality should meet the requirements of the specifications. After the welding construction is completed, the overall skeleton should be treated with rust prevention and anti-corrosion.

4.3.3 次骨架及细部造型 塑石假山中的次骨架与强部造型用料，一般用园钢和线 材。在连接主骨架间表面的同时着力推敲塑石结构主次关系和 高低起伏的变化效果，在山体中慎重地构划出山体、山脉的质 感与瀑布、溪流、树木的协调。巧妙艺术地留设植物种植穴， 植物种植穴的位置应错落有致，力求自然。

4.3.3 The materials used for the secondary skeleton and strong part of the plastic stone rockery in the secondary skeleton and detailed modeling are generally made of round steel and wire. While connecting the surfaces between the main skeletons, we focus on exploring the primary and secondary relationships of the plastic stone structure and the effect of fluctuations in height. We carefully delineate the texture of the mountains and the coordination with waterfalls, streams, and trees in the mountains. Cleverly and artistically setting up plant planting holes, the positions of plant planting holes should be arranged in a staggered manner, striving for naturalness.

4.4 钢网绑扎 在钢筋网格表面绑扎钢网前，先把钢网剪成3-5 小片，依照钢筋网格的高低起伏逐块绑扎固定，再根据设计山体质感纹理的造型要求，进行局部敲压修整处理。

4.4 Steel mesh binding: Before binding the steel mesh on the surface of the steel mesh, first cut the steel mesh into 3-5 small pieces and fix them one by one according to the height fluctuation of the steel mesh. Then, according to the design requirements for the texture and texture of the mountain, perform local tapping and trimming treatment.

4.5 挂浆打底 水泥砂浆加入适量纤维性附料及107建筑 胶水，以增加山石表面抗拉强度和砂浆的粘韧性，山体外挑部 位的底部挂浆，应在钢网上面铺挂，砂浆应挂满整个网面，打 底挂浆施工完24 小时后进行不间断浇水养护。

4.5 Adding an appropriate amount of fibrous additives and 107 building adhesive to the cement mortar for hanging slurry and bottoming to increase the tensile strength of the stone surface and the adhesive toughness of the mortar. The bottom hanging slurry of the overhanging part of the mountain should be laid on the steel mesh, and the mortar should be hung all over the entire mesh surface. After 24 hours of construction, continuous watering and curing should be carried out.

4.6 山体纹理粗造型 造型方法有增设钢网、砌砖、塑粉水泥砂等。根据设计 要求及整体塑山风格，对山体中的山脉、峰峦、洞穴、溪流、 断层、壁顶、石纹等外部轮廓进行粗步造型制作，整体效果达 到造型自然、比例适当、整体连贯性强。

4.6 The methods for rough modeling of mountain texture include adding steel mesh, laying bricks, and using plastic powder cement sand. According to the design requirements and overall mountain shaping style, rough steps are taken to shape the external contours of mountains, peaks, caves, streams, faults, wall tops, stone patterns, etc. in the mountain, achieving a natural shape, appropriate proportion, and strong overall coherence.

4.7 山体面层 按假山整体造型表面塑粉一层20 毫米厚的1:2.5 水泥 砂浆，并塑粉出山石的质感纹理。待砂浆未完全凝结时，用铁 抹子及沟缝刀等塑石专用工具进行山体表面造皴处理。

4.7 The surface layer of the rockery is shaped as a whole, with a layer of 20mm thick 1:2.5 cement mortar coated with plastic powder on the surface, and the texture and texture of the rocks are formed by plastic powder. When the mortar is not fully set, use plastic and stone tools such as an iron trowel and a groove cutter to make cracks on the surface of the mountain.
