In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the bilge well provided by this embodiment is provided with a bilge well anti-leakage well cover at a well mouth of the bilge well, and the bilge well anti-leakage well cover comprises: well lid body, buffer cylinder 2 and breather pipe 3. Four mounting seats 4 are fixedly mounted on the inner side wall of the bilge well body 11 close to a well mouth through expansion bolts 5, and the four mounting seats 4 are uniformly arranged in the well body 11. The butt of well lid body is installed on mount pad 4, and in buffer cylinder 2 extended to well body 11, be provided with the cavity sealing strip 6 as the sealing member in succession between well lid body and the mount pad 4. In order to avoid well lid body edge to have the gap to lead to sewage not directly to enter into well body 11 through buffer cylinder 2.

The well lid body is the structure of permeating water, including the upper well lid 12 of the concrete material that permeates water of locating the upper strata and locate the prevention of seepage well lid 1 of the organic material of lower floor, is provided with the delivery port on the prevention of seepage well lid 1, and buffer cylinder 2 installs on the delivery port to seal the delivery port completely. The upper well cover is provided with a through hole to accelerate the speed of accumulated water flowing into the well mouth. Buffer cylinder 2 sets up towards the one end opening of well lid body, and buffer cylinder 2 keeps away from the one end demountable installation of well lid body has shutoff lid 7. The opening of the buffer cylinder 2 is hermetically connected with the well lid body; a floating baffle 9 is movably arranged in the buffer cylinder 2, and a water flowing hole 8 is arranged on the buffer cylinder 2 in a penetrating way.

The breather pipe 3 is arranged in the inner cavity of the buffer cylinder 2, the breather pipe 3 is an arc pipe, and the axes at the two ends of the breather pipe 3 are vertically arranged. One end of the vent pipe 3 penetrates through the side wall of the buffer cylinder 2, the other end of the vent pipe is arranged towards the floating baffle 9, and the floating baffle 9 has a first state of floating upwards to completely close one end of the vent pipe 3 and a second state of floating downwards to completely open the vent pipe 3.

The discharge orifice 8 is arranged on the side wall of the buffer cylinder 2, which is deviated from one side of the well lid body, of the floating baffle 9, a baffle limiting part is arranged between the discharge orifice 8 and the floating baffle 9, and when the floating baffle 9 is in the second state, the baffle limiting part is in butt fit with the floating baffle 9.
