Drainage Around Detached Garage
嗨希望东北的每个人都有风暴安全。我有一个带有新屋顶的2辆车独立的车库，但在非常大的雨中，我在车库里得到了地面水。我相信其中一些只是在旧车库门下的山丘旅行。然而，后左角也收集水，不在左侧门附近。我在车库和右侧的草地上有一个摇滚。除了在车库前面添加长漏，门还想知道我是否需要在车库的整个右侧和背面围绕车库的外部排水管。草地淹没了这场风暴，所以这是大量的水。附有的图片。

If I were Pharaoh, I would have put a perimeter drain around the pyramids. I'm a firm believer that water shouldn't stand at any place on a property if it can be helped.
You may find simple rain gutters will eliminate this problem. Remember that all the rainfall that falls on the roof of a structure is concentrated at the eaves when it runs off. If you let this run off to the ground along the eaves, those areas are getting the equivalent of torrential rains even in a light storm. Rain gutters help to carry this water array and direct it away from the structure so that you don't have problems.
我会尝试在这里安装jutters。无缝的排水沟是最好的，但PVC排水沟是一个相对便宜和快速的DIY项目。确保当您规划系统时，您正在排出足够远离结构的管道，也可以尽可能地朝向结构的下坡侧。

感谢您的建议，我确实有雨水沿着屋顶跑步。它倾向于属性后方，但我想系统中可能存在错误。沿着后面和侧面我可以把东西放在适当的地方，摆脱地面水并排水吗？在沥青的车库前面的炉排和排水有意义，但我可以在一侧和背部覆盖它吗？这是后院的一部分，我不想在紧张的院子里放松更多的空间。
你可能会尝试法国流失。用袜子拿起一些穿孔的排水管，将其埋在干净的砾石中。将管道排放到任何地方想要水中下坡。您也可以在草地下放置这样的法国流失，但是由于水将需要更多的时间来通过草皮进入排水，而通过砾石床。
Note that if you do all this work trenching in drains, I'd recommend building the drain system so that it can handle the runoff from your gutters too. That way you can direct ALL the water to somewhere away from the structure.

我会加那个 -
Don't run the gutters into a perforated pipe that runs along the base of your building if you can help it. A non-perforated pipe carrying the water away would be ideal, unless you need to drain along the way of the whole path.
Right, ideally you have two pipes running away from the building, one for the gutters and one for the perimeter drains. Once they get one pipe diameter below the perimeter drains they can join and exit together.
Hopefully drains + slope/gravity can remove the water from the garage area.
If not, you can have drain pipes bringing the water to a grass covered dry well. Be sure to make it large enough (perhaps 6'x'6'x6').
如果这对你不起作用，你可以将排水水泵出来更小的油底壳。
所以我画了一张我处理的东西的照片。原始计划从车库的右侧射出水，但物业后部有一个挡土墙。如果我挖下然后钻一个挡住墙，我害怕它会破坏墙壁。到物业后部是商业企业。从车库门的左侧开始，我思考射击右边的管道，然后将其伸出到车库的一侧，然后肘击到距离车库的院子里的圆顶。不确定这是否太多了。我也不想挖掘一个深孔的管道。我的起始深度是多少，我有多深，所以我可以在一侧的顶部种植草。也是如果我在院子里的车库前面投球到干得干燥的话。让排水沟在后方挡住挡土墙上，只需用砾石沿一侧挖沟，盖上草地，所以表面水将下降下方。
You don't really need any particular depth, but if the line is very near the surface it will be more liekly to get damaged. If you can only get the line in a few inches underground, I would use schedule 40 (or even scheduel 80) pipe, and NOT the cheaper schedule 30 stuff with the bell ends that is thinner walled.
Typical pitch is 1/8" to 1/4" per foot, which is 1-1/4" to 2-1/2" slope per 10 foot stick of pipe. Steeper slopes create faster flow, and allow for more water to be carried by a given size pipe. There are charts to help you size the pipe based on the expected rainfall rates in inches per hour for your area.
Note that smooth-wall pipe is much less prone to clogging than the corrugated stuff.

I realize you are dealing with a slab, not a full basement, but this detail and related resources could be helpful:Underground Water Barrier Retrofit.
