為預(yù)防塑石千層石假山開裂，能夠在施工時對原料混凝土停止處置。但是假如在運(yùn)用了若干年后，千層石假山塑石呈現(xiàn)掉色以至開裂問題怎樣辦呢？
In order to prevent the cracking of plastic rockery rockery, the raw concrete can be stopped during construction. But what if, after several years of application, the rockery stones show discoloration and even cracking?
GRC塑石千層石假山采用原石脫模拼裝，由于仿真度高、施工工期短等優(yōu)勢，在國內(nèi)曾大量制造。
GRC plastic rockery is assembled by demoulding of raw stone. Because of its high simulation and short construction period, it has been manufactured in large quantities in China.
近幾年，在GRC塑石千層石假山運(yùn)用期的5年至10年之間，呈現(xiàn)了各種問題。小問題有：千層石假山外表掉色、千層石假山拼接縫開裂等，大問題有：千層石假山破損、倒塌、移位等。以上問題的呈現(xiàn)有工藝的問題也有制造質(zhì)量問題。
In recent years, there have been various problems in the application period of GRC plastic rockery rockery from 5 to 10 years. The minor problems are: the appearance of the rockery fades, the joints of the rockery crack, etc. The major problems are: the rockery damage, collapse, displacement and so on. The problems mentioned above are not only the legacy of technology, but also the quality of manufacturing.
千層石假山外表掉色及拼接縫開裂這些問題主要跟GRC資料的特性及施工工藝有關(guān)。
The discoloration of rockery appearance and cracking of splicing joints are mainly related to the characteristics of GRC data and construction technology.
GRC千層石假山巖片在制造過程中，面層通常采用素漿噴涂工藝，素漿凝固后構(gòu)成紋理外表，素漿中無沙石等骨料的參加，構(gòu)造性會大大降低，后期會構(gòu)成零落，千層石假山外表顏色的零落，其實(shí)就是素漿的零落，拼接縫開裂跟GRC水泥的強(qiáng)度有很大的關(guān)系，GRC水泥與普通硅酸鹽水泥相比，特性是快速凝固，缺陷是凝固后的構(gòu)造強(qiáng)度較差。
In the manufacturing process of GRC rocks, the surface layer is usually sprayed with plain slurry. The plain slurry solidifies and forms texture appearance. Without the participation of aggregates such as sand and stone in plain slurry, the structure will be greatly reduced. Later, it will form fragments. The color of rocks surface is actually the fragmentation of plain slurry. The cracking of splicing joint has a great relationship with the strength of GRC cement. GRC cement has a great relationship with ordinary Portland water. Compared with mud, it is characterized by rapid solidification, and the defect is that the structural strength after solidification is poor.
以上的問題均能夠采用簡單修復(fù)的工藝完成，拼接縫開裂修復(fù)采用GRC水泥重新涂抹、粘合，重新作色也能處理千層石假山的掉色問題。
All the above problems can be solved by simple repair technology. GRC cement is used to re-coat and bond the splicing cracks, and re-colouring can also deal with the discoloration of rockery.
假如是千層石假山塑石內(nèi)部的鋼構(gòu)造選材和焊接不到位，會招致GRC千層石假山后期的破損，以至倒塌，如立即采取修復(fù)，能大大進(jìn)步千層石假山的運(yùn)用壽命，如若耽誤太久，內(nèi)部骨架受損率較高，則無修復(fù)可能，只能推倒重建。
If the steel structure inside the rockery is not selected and welded properly, it will lead to the later damage of GRC rockery, and even collapse. If immediate repair is taken, the service life of rockery can be greatly improved. If the delay is too long and the damage rate of internal skeleton is high, it is impossible to repair, only to push down and rebuild.
因而好的方法就是將問題扼殺在施工完畢前，有經(jīng)歷的工程隊(duì)會在千層石假山塑石制造中就將這些問題思索進(jìn)去，用質(zhì)量好的原料和鋼材制造塑石千層石假山保證在試用期內(nèi)盡量沒有大的問題發(fā)作。
Therefore, the best way is to strangle the problems before the completion of construction. Experienced engineering teams will think about these problems in the process of making rockeries, and make rockeries with good quality raw materials and steel to ensure that no major problems occur during the trial period.
