定制法式沟槽排水设计特定土壤和洪水
我住在农村公司，在我的院子里融合粉质细腻的污垢和粘土。在春天的雪融化和闪日下，我在这部分院子里得到了一些站立的水。我的50岁，4英尺高的爬行空间，我也得到了一些水（仅在1/5的区域）。它在家里的同一侧大约48英寸，10英寸距离沟槽的同一侧约为48英寸，同样的距离水架。
所以我要安装一个12英寸宽的沟槽沥水，如此。请告诉我我是否错过了任何东西或需要考虑其他人。谢谢！
For 55′ long trench dig 24″ deep at beginning point and be 32″ at deep at outlet.
马克所有公用线路与明亮的磁带,袖子them with hard conduit if possible, or bind small pieces of smooth metal protection around them (as safety shields), and extend flags up above the surface, which my dogs will likely pull up promptly, lol.
Place 4.5′ wide (at minimum) permeable landscape cloth down the bottom and lay it across and out of the sides. The extra will be used to fold over each other on the upper layer of gravel.
Place 8″ deep of 1″ to 2″ round washed river gravel down the bottom of trench.
将45或90°（顶部）弯头放在高端以进行检查和清洁。出口端应该理想地达到日光，但如果不可能，那么一个充满岩石的足够大的收集孔。如果暴露于阳光管，应筛选以阻止害虫。
Drill a pair of 1/2″ holes every 6″ down the 4-5″ dia pipe, slightly offset (about 1″ away from the center of the bottom). Or use pre-drilled pipe if available.
将管道放在8英寸的砾石上。再次检查它的斜率。
Do NOT permanently cement PVC joints except for the elbow joints. Wrap with plastic wrap and duct tape. This is so I can pull them up hassle free if needed.
Place another 6″ of gravel over the pipe.
将景观布放在两侧。
Fill the remainder up with gravel to surface.

安迪，
Nobody drills holes in solid pipe to make perforated pipe any more. Buy the perforated pipe.
Your specs are fine. I haven't seen 5" pipe -- your choices are probably 4 inch or 6 inch pipe. Buy the 6 inch pipe if you can afford it.
I don't see why you want to bury the pipe that deep -- although you can if you want. Deep pipe is harder to dig up and fix if there is a problem.
另一种方法是将塑料捕捉盆放入湿地方的中心 - 然后将排水管安装到捕获盆地的日光。如果您愿意，可以穿孔的前10英尺的管道，其余的固体。这样，您的管道靠近捕获盆地附近约8英寸到14英寸 - 在排水端的深管（用于斜坡）。
谢谢。我将利用一些固体4“PVC和我手头的关节......因此钻孔。
I'm wondering if I even need pipe. The water is slow to accumulate over several weeks. We have a few weeks of repeated freeze-snow-thaw-freeze-snow-thaw, etc. The soil is high clay near the top so it gets trapped in a 700 SF (25' x 30' rectangle) low area and then seems to saturates the soil and slowly makes way to my crawlspace about 20' away. I am placing the trench just inside that low area about 15' away from my house.
So I think I may have soil saturation problems that come from the surface clay and also possibly soil water from water table pressure. So I'm planning it 24"-32" deep trying to attract as much water from both sides as I can and dumping it down hill about 25' from house corner.
雅认为梧桐布封装了1-1 / 2“到3”克里克碎片会很好，而我得到的少数/短雨水？我没有用任何东西覆盖顶部砾石，但在表面下，双层布将是6英寸。
Is it possible to regrade so the water drains away from your crawlspace? If not, could you use grading and a swale to channel the water? Either option might be simpler and cheaper. I've installed a few French drains, and they can be a PITA to get right. Plus, most drains silt up eventually (which is why you don't want them too deep).
没有任何其他选择在那边没有空间。我必须是我害怕的一些排水瓷砖。
如果您进入园艺，您有时可以通过安装沼泽花园来解决池塘。
不能。有些东西和一条小道，我必须在另一边进入......和我的丙烷坦克。我可能会把沟槽剪掉，试着让一些高度改变在某处，以避免沟槽。我只是不确定，如果我真的应该浪费$和时间将4英寸的PVC管子放入砾石中间，或者只是使沟槽包裹在景观布中，并用光滑的1.5到3“河砾石填充。音量不高，它只是因为粘土和饱和而不是足够快，所以我已经观察到了。从我的理解，管道对于快速移动和大量的水上流动非常重要。
安迪，
仅排水岩石可能只是正常工作。穿孔管是好保险，但如果你不想花钱，你总是可以在没有它的情况下尝试做，如果岩石证明不足，请挖掘它并加入管道。
是的，我可以只使用摇滚，如果需要，请把管子放在浅浅之后，就像马丁建议一样。就在表面下面，覆盖着3英寸的砾石，罕见的硬降雨。只需摇滚即将更简单的准备和材料。
