Further, during being provided with the middle of the blind plate for closing and closing after drainage well Yield rainfall relation switch valve
Door.
Further, the controlled valve on the blind plate is closed mode.
Further, the blind plate is located at sole plate layer.
By such scheme, the present invention at least has advantages below：
A kind of drainage well closing mode of pre-buried annulus of the present invention, simple in construction, easy construction, with pre-buried annulus,
Drainage well precipitation work is carried out using blind plate special tectonic while carrying out full weld with blind plate periphery, to reach in dry environments
Blind plate is subjected to annulus, had the characteristics that simultaneously：
1st, prefabricated blind plate has globality, and completely enclosed effect is reached using groove full weld；
2nd, using valve precipitation it is subjected to, constructs in dry environments while；
3rd, carry out waterproof on blind plate and casting concrete reaches closed for second time effect.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,
And can be practiced according to the content of specification, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.
