Abstract
The utility model relates to an inspection well capable of smoothly draining water. The inspection well comprises a wellhole, a well seat and a well cover, wherein a plurality of countersunk head screw holes are formed in the well cover and are provided with conical surfaces, circular arcs bulged outwards are formed at the joint parts of the conical surfaces and the upper surface of the well cover, and the plurality of countersunk head screw holes are peripherally and uniformly distributed on the well cover. The inspection well capable of smoothly draining water has the advantages that as the plurality of countersunk head screw holes are formed in the well cover, rainwater directly flows down from the conical surfaces of the countersunk head screw holes along the well cover, the water receiving areas of the countersunk head screw holes are also enlarged, meanwhile, the strength of the well cover is not influenced, the structure is simple and practical, and the problem of water accumulating on the well cover is effectively solved.
Description
Technical field
The utility model relates to a kind of manhole, relates in particular to the unimpeded manhole of a kind of lower water.
Background technology
Present manhole generally has several through holes on the well lid, but because there is not guiding device, water is difficult to oneself trickle to the through hole.
The utility model content
The technical problems to be solved in the utility model is: check the unimpeded not problem of mine water in order to solve, the utility model provides the unimpeded manhole of a kind of lower water to solve the problems referred to above.
The technical scheme that its technical problem that solves the utility model adopts is: the unimpeded manhole of a kind of lower water, comprise pit shaft, well seat and well lid, offer a plurality of sunk screws hole on the described well lid, described sunk screw hole has the conical surface, cambered outwards circular arc is arranged in the junction of the described conical surface and well lid upper surface, and described a plurality of sunk screws hole circumferentially is distributed on the well lid.Offer a plurality of sunk screws hole on the well lid, rainwater can go downstream along the conical surface of well lid from the sunk screw hole, and the sunk screw hole has also increased the area of water receiving, does not affect the intensity of well lid simultaneously.
Further, specifically, described sunk screw hole has 4.
For so that lower water is more unimpeded, be provided with many guiding gutters around each sunk screw hole.The setting of guiding gutter so that water better flows into the sunk screw hole, enters in the pit shaft.
The beneficial effects of the utility model are, the unimpeded manhole of water under the utility model, offer a plurality of sunk screws hole on the well lid, rainwater can go downstream along the conical surface of well lid from the sunk screw hole, the sunk screw hole has also increased the area of water receiving, do not affect simultaneously the intensity of well lid, simple and practical, effectively solved the problem of ponding on the well lid.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the distribution map in the sunk screw hole on the well lid of the manhole that water is unimpeded under the utility model;
Fig. 2 is sunk screw pore structure schematic diagram on the well lid of the manhole that water is unimpeded under the utility model.
Among the figure 1, well lid, 2, the sunk screw hole, 3, the conical surface, 4, guiding gutter.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 1-2, the unimpeded manhole of water under the utility model, comprise pit shaft, well seat and well lid 1, offer a plurality of sunk screws hole 2 on the well lid 1, sunk screw hole 2 has the conical surface 3, and cambered outwards circular arc is arranged in the junction of the conical surface 3 and well lid 1 upper surface, and described a plurality of sunk screws hole 2 circumferentially is distributed on the well lid 1, described sunk screw hole 2 has 4, is provided with many guiding gutters 4 around each sunk screw hole 2.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the manual, must determine its technical scope according to the claim scope.
