Description

Safety well cover for building

Technical field

The utility model relates to building field, especially relates to a kind of Safety well cover for building.

Background technology

Existing drainage manhole cover is made of metal more, and its structural strength is poor, and nowadays along with growth in the living standard, car is more and more, and well lid suffers the pressure of car for a long time, easily deformation, and cannot recover, and causing the sinking of ground at well lid edge, well lid is easily stolen; In order to strengthen the effect of draining, more drain hole also can be set on well lid, the pipeline of down-hole enters Ha Noi by purification of waste water after meeting discharge standard, and rainy day river water level goes up, cause river to pour in down a chimney, the impulse force of river can wash away well lid, and river flooded road surface causes passerby's inconvenience of walking, even vehicle is also impassable, passerby also cannot see pithead position clearly, very dangerous, the joint face imbalance of well lid and well seat, when pressing road surface, vehicle easily produces noise, lid and the collision of well seat, easily damage, and shortens its application life; And the article that volume is little are fallen in well and cannot be fetched, the valuables such as the necklace of especially making as gold and silver, lose very large, simultaneously impurity enter in also can block underground passage, cause water to flow.

Utility model content

The utility model, in order to overcome the deficiencies in the prior art, provides one to avoid losing, and sound construction, also can efficiently prevent the Safety well cover for building that river pours in down a chimney.

To achieve these goals, the utility model is by the following technical solutions: a kind of Safety well cover for building, comprise concrete lid and wellhead receptacle, the outer race of described concrete lid is provided with steel ring, the steel plate bar that in concrete lid, along continuous straight runs raises up in the middle of being interval with; Concrete lid soffit is provided with the sleeve of reverse frustoconic, one end that sleeve openings is larger is connected with concrete lid soffit, concrete lid is positioned at cylinder and is provided with water-guiding hole, and the outer wall of sleeve is provided with at least 2 projections, and wellhead receptacle inwall and projection corresponding position are provided with L shaped slot; Sleeve openings is provided with a block plate under less one end, and block plate edge and concrete lid are fixed; Described block plate has middle recessed overhead gage and the middle lower baffle plate raising up; Welding in the middle of overhead gage and lower baffle, overhead gage is connected by bracing piece with lower baffle edge.

As preferably, the two ends of described bracing piece respectively with overhead gage and lower baffle welding, described concrete lid soffit and wellhead receptacle contact position are provided with cushion, the edge of described block plate extends upward the reinforcing mat being fixedly connected with concrete lid soffit.

In sum, the utlity model has following advantage: this steel plate bar and cushion strengthen lid ability to bear, avoid deformation, sound construction, stable, makes the compressive property of lid and wellhead receptacle stronger; Described sleeve and block plate can guide the water flowing down in water-guiding hole, stop that river pours in down a chimney; Block plate also can be caught the article of falling into the small size in well, avoids property damage.
