Before making rockery, we must have confidence in which rockery to make and which rockery foundation need to be determined, otherwise it is impossible to start. What are the technical points of rockery foundation? It's a little complicated. It can't be explained in a word or two. Therefore, Jinan rockery production small edition for you to sort out, hope to help you.
What are the technical points of rockery foundation? Rockery production must know!
目前，假山制作的基本工艺分为:1、灰桩基础;2. 灰浆砌块石基础;3.混凝土基础;4. 桩基础;5. 石灰的基础;6. 石钉夯土基础。假山制作，假山的基本技术要点如下(特别注意:具体施工操作要看假山制作施工图纸，以下一些数字、参数都是我们具体工程，不能硬拷贝!):
At present, the basic technology of rockery making includes: 1. Ash pile foundation; 2. Mortar block stone foundation; 3. Concrete foundation; 4. Pile foundation; 5. Lime foundation; 6. Stone nail rammed earth foundation. The basic technical points of rockery production are as follows (special attention: the specific construction operation depends on the rockery production construction drawings, and some of the following figures and parameters are our specific projects, not hard copies!):
1. Ash pile foundation: it is a rockery foundation formed by drilling evenly on the ground and then filling with lime for compaction. The lime in the pile hole expands and solidifies after absorbing water to make the ground firm. It is generally used as a simple foundation for small rockeries.
2. Mortar block stone foundation: a layer of stone with thickness of 300-500mm can be built with 1:2.5 or 1:3 cement mortar for rockery fabrication; the cement mortar used for underwater masonry shall be 1:2. 30mm thick coarse sand can be laid under the block stone base as the leveling layer, and the foundation shall be compacted. Mortar and grouting can be used for masonry block stone and cement mortar.
3. Concrete foundation: 30-70mm thick sand and stone cushion can be made above the flat soil compaction layer; above the cushion is the basic layer of concrete. The thickness and strength of the ground concrete layer can be designed as 100-200mm, and C15 concrete is used. The underwater thickness is about 500mm and the strength is C20. Under the condition of solid foundation such as rockery construction, it is possible to excavate and level the earth trough to pour concrete foundation.
4. Pile foundation: the rockery foundation is made of wood piles or concrete piles, i.e. pile foundation. Pile foundation is mainly used for soft soil or new backfill places. Generally, Chinese fir or cypress pile is used as pile foundation, with pile diameter of 10-15cm, pile length of 1-2m and pile bottom in sharp shape. For the concrete pile foundation, the prefabricated concrete pile shall be designed first, and the pile end is still sharp. The stakes are arranged in the form of plum blossom, with a spacing of about 20cm. The top of the pile material can be exposed to the ground or the lake bottom 10-30cm. In this process, small stones are closely inlaid and leveled, and then a layer of granite or other stones are laid on the top as the top stone of the rockery pile foundation. Another method is to pave and compact the top surface of the pile foundation to form the pile foundation.
5. Lime Foundation: it is mainly composed of lime and plain soil in the proportion of 3:7. Each layer of lime soil is 30cm thick and compacted to 15cm thick, which is called first class lime soil. Generally, the height of rockery is more than 2m, and its lime soil foundation can be designed as grade I plain soil plus grade II lime soil. For the rockery below 2m, it can be designed by adding lime soil step by step.
6. Rammed earth foundation with stone nails: it uses sharp stones to hit the ground, so that the soil of rockery is compacted, and then a layer of flat soil or lime soil is pressed on it. Generally used as the base of low rockery.
It should be noted that: artificial earth mountain and low rockery generally do not need foundation, and the mountain is directly on the ground. When the height of the rockery is more than 3m, proper foundation shall be considered. Generally speaking, when making large and thick rockery, concrete foundation or block stone slurry foundation should be selected; the rockery height and weight are moderate, and lime foundation or pile foundation can be used.
