The gravel layer is used for drainage of the blind ditch and can support the structural bottom plate, the first geotechnical cloth layer, the water guide grid layer, the polyethylene protective film layer and the plain concrete cushion layer which are sequentially arranged on the top surface of the gravel layer can better isolate the structural bottom plate from the blind ditch, and the better water passing capacity can be continuously kept when the water amount in the blind ditch is larger, so that the safety of the basement bottom plate is ensured. The setting of observation tube in the observation well for subaerial personnel can look over the groundwater condition of french drain through the observation tube, and the observation tube bottom is equipped with bores the flower hole, then wraps with the second geotechnological cloth layer, like this, when guaranteeing to intake, can prevent again that debris from entering into in the observation tube, guarantee the intraductal cleanness of observation. Can the water pressure condition in the real-time supervision observation tube through the manometer subassembly, when water pressure is great, can be through the quick understanding of manometer subassembly to can take emergent sluicing decompression measure rapidly.
Preferably, a third geotextile layer is arranged in the blind ditch body.
The utility model discloses in, the stable in structure of blind ditch body is favorable to in setting up of third geotechnological cloth layer.
Preferably, the observation tube is provided with an exhaust valve.
The utility model discloses in, discharge valve can control the gas emission in the observation tube to control the atmospheric pressure in the observation tube effectively.
Preferably, the pressure gauge assembly is connected with an external water pressure automatic monitoring device.
The utility model discloses in, the manometer subassembly is connected with the automatic monitoring facilities of external water pressure, like this, can automatic monitoring water pressure, the automatic control drainage.
