drain pipe安装不在contract里，必须赶在contractor backfill之前把pipe给装上，
为了能够让pipe slope，就得先back fill一部分。开始没把这点backfill当回事，我
老人家已经刨树根挖土忙活了多半年了，后院的小山已经被我挖掉一半了，以为只是往
坑里添一层薄土，很简单。大汉淋漓的干了两个小时发现自己的想法太简单了，要回填
的土根本不是一点，是相当的多，尤其到了坡度的高处，几乎要添满将近一半的高度，
而且坑边的表层土已经被推土机推到远的地方，非表层的土异常坚硬，一镐狠狠的刨下
去，只能刨动一点点，没有土源拿什么回填？！一小车一小车的从远处运土就更麻烦了
，星期天当天完成pipework就几乎是不可能完成的任务了，而contractor星期一就来
backfill了。着实让我紧张了一下，只有改变策略，变回填为在墙的侧面固定，于是冲
到HD买来了一堆估计能用得上的东西（后来证明有好几样都没法用，算是交了学费了）
，又就地取材利用钢筋的边角料做支撑，简直就是和时间赛跑... 阅读全帖 |

但是如果放到新的上，那怎么改hash?
肯定要用hierarchical 的hash,比如，如果hash%7==1, 这些hahs被再次hash为0，1，
为0的去旧server,1的去新server,但是这个缺点是旧的已经满了，而且给你一个hash,

发帖数: 64 | 31 不知道你说的两个地基是什么样的，怎样的结构，照片？一般地基就是三种：
basement, craw space和slab on ground。材料可以是concrete, masonry block等。
basement和crawspace下面一般是footing。把上面承受的力，均匀分布到下面的土壤中
。slab on ground，下面是5~7 英寸厚的gravel。
如果原来是湖，地势低。常见的做法是：把湖添平，backfill。当然回填的土会比较松
软，然后打桩，一直打到下面很实的土壤中，或者岩石上。这个中国美国做法都一样。
friction pile。做成friction pile foundation。就和那个“楼倒倒”照片的地下部
分一样。上面是该建什么建什么。不过这也只是算一个“地基”阿。
friction pile这种方法是很常见的，也是经过时间考验的。一般美国居民住宅用的少
，是因为成本太高。大那么多桩，才建一个2-3层的house，太不划算。 |
