我国南方盛产竹材,价格低廉,在地方道路修建中、小桥和涵洞时使用竹桩,既能节约钢材、水泥和木材等主要建筑材料,又能降低造价。我们认为竹桩基是使用竹材的一个良好的发展途径。因此,在这里提出桥梁桩基础可以就地取用竹材的新措施,这是富有革命的现实意义的。这里我们先介绍越南民主共和国关于竹材使用方面的民间经验,这些经验是非常可贵的。 1、越南民间的竹材防腐方法:他们习用的简便防腐方法是将新伐竹浸泡在水塘里,并将竹压入水中,不使浮起,经过一个月取出使用,可以保持约在两年时间内不发生菌虫腐蚀;如浸泡时间延长到八个月或一年,就可以保持长时期不发生菌虫腐蚀。这一民间经验,和印度科学家在波罗哥黎岛对竹材腐蚀问题研究的结果是互相一致的。(即将新伐的竹浸水八个星期,可以提高受害安全率至94％)这是因为竹子中含有糖份,容易招致菌虫;如把新伐竹长时间的压在水中浸泡,便有去糖 Bamboo is abundant in the south of our country, and its price is low. Bamboo piles are used in the construction of local roads, small bridges and culverts, which can not only save the major building materials such as steel, cement and timber, but also reduce the cost. We think bamboo piles are a good way to use bamboo. Therefore, here proposed new measures can be taken in situ bamboo bridge pile foundation, which is revolutionary practical significance. Here we first introduce the experience of the Democratic Republic of Vietnam on the use of bamboo folk experience, these experiences are very valuable. 1, Vietnamese folk bamboo preservative method: The simple preservative method they used is to soak the new cut bamboo in the pond, and the bamboo into the water, not to float, after a month to remove the use, you can keep about two years Bacteria do not occur within the time of corrosion; such as soaking time is extended to eight months or one year, you can maintain a long period of non-occurrence of insect corrosion. This folk experience is consistent with the findings of Indian scientists on the issue of bamboo erosion in the island of Poros. (Freshly planted bamboo flooding eight weeks, can increase the victim safety rate to 94%) This is because the bamboo contains sugar, easily lead to bacteria and insects; such as the new cut bamboo in the water for a long time soaking, there is to go sugar
