Description
Technical field
The utility model belongs to urban operating mechanism technical field, relates to the sewer mouth well lid being positioned on road surface, especially relates to a kind of manhole cover structure that can be locking.
Background technology
When traditional well cover for sewer designs, generally circular well lid is directly covered on the step of sewer mouth, for sealing the sewer mouth that is positioned at road surface, in order to avoid affect the normal use of road, and when sewer need to be dredged or keep in repair, can be easier to open again well lid, enter construction of sewer.Traditional well lid adopts cast iron to make conventionally, and stolen phenomenon is very serious, has brought safely great potential safety hazard to road surface; Afterwards by technological improvement, adopt the new pattern manhole cover of the making such as polymer, packing material, reinforcing material to have substituted traditional well lid completely, this well lid does not have recovery value, thereby has solved usually stolen problem of well lid.Yet, while meeting with extra torrential rain, the drainability of municipal sewage system breaks through the upper limit, the rainwater that well lid is usually overflowed in sewer fast rushes, because sewage covers road, pedestrian's driving cannot be found the well head of opening greatly in time, cause great threat to pedestrian and traffic safety, and the tragedy being caused by well lid all occurred and reported in national urban, once having caused the whole society to the concern of sewer well head safe and thinking.In can city, well lid be thousands of, is difficult to whole monitoring managements, and placing hope on administrative department is unpractical by dropping into that manpower and materials monitor.
Utility model content
In order to address the above problem, the utility model provides a kind of manhole cover structure that can be locking, thereby reaches good safe effect.
The utility model is achieved by following technical solution.
A kind of manhole cover structure that can be locking, comprise base and inner cap, described base is annular, and upper surface is provided with the ring-shaped step concentric with base, and described inner cap external diameter is greater than the internal diameter of base, inner cap is arranged on the base inner edge in ring-shaped step, described inner cap periphery is provided with lug, and ring-shaped step is provided with the mounting groove corresponding with lug, and the lug correspondence inside covering is arranged in mounting groove, and being connected locking with base, ring-shaped step is provided with enclosing cover.
Described lug is at least 3, along the periphery of inner cap, is uniformly distributed; Between described lug and base, be connected by screw; Described enclosing cover periphery has been provided with cover slot, plays the outer horizontal edge that covers corresponding to cover slot and is provided with cue mark; In described, cover and be provided with covered hole.
The beneficial effects of the utility model are:
A kind of manhole cover structure that can be locking described in the utility model, by establishing ledge arrangement at inner cap edge, and is connected lug locking with base by screw, reached the fixing locking effect of well lid, avoids by water, being washed open easily in rainy season; By establish outer cover structure on ring-shaped step, on the one hand can prevent that silt impurity from entering in mounting groove, avoid mounting screw corroded fast or surrounded and cannot take off by silt, on the other hand when well lid is worn need to change time, can only change enclosing cover, reduce its maintenance cost; Even and enclosing cover damage to lose efficacy, inner cap still can guarantee well head safe, or need to safeguard when inner cap, enclosing cover also can be used as interim well lid and guarantees pedestrian's traffic safety; The quantity of lug is at least 3, can guarantee the stability that inner cap is locked; Enclosing cover and in cover and established respectively cover slot and covered hole, be convenient to instrument, well lid be opened.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is arranged on the structural representation on roadbed.
In figure: 1-enclosing cover, 11-plays cover slot, 12-cue mark, 2-inner cap, 21-lug, 22-screw hole, 23-covered hole, 3-base, 31-ring-shaped step, 32-mounting groove, 4-screw, 5-roadbed.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As Fig. 1, shown in Fig. 2, a kind of manhole cover structure that can be locking described in the utility model, comprise base 3 and inner cap 2, described base 3 is annular, upper surface is provided with the ring-shaped step concentric with base 31, described inner cap 2 external diameters are greater than the internal diameter of base 3, inner cap 2 is arranged on base 3 inner edges in ring-shaped step 31, described inner cap 2 peripheries are provided with lug 21, ring-shaped step is provided with the mounting groove corresponding with lug 21 32, lug 21 correspondences on inner cap 2 are arranged in mounting groove 32, and be connected locking with base 3, ring-shaped step is provided with enclosing cover 1, between described lug 21 and base 3, by screw 4, be connected.
During installation, first base 3 is installed to the well head place of roadbed 5, maintenance base 3 is concentric with well head, and by concrete, base 3 is pre-buried fixing, reserves the installation site of enclosing cover 1 at the upper semisection of ring-shaped step 31; Then inner cap 2 is installed on base 3, makes the lug 21 on inner cap 2 corresponding one by one with the mounting groove 32 on base 3, with screw 4, by the screw hole 22 on lug 21, inner cap 2 and base 3 are connected and fixed; Finally enclosing cover 1 is directly covered to ring-shaped step 31 end faces at base 3, complete installation.
Described enclosing cover 1 periphery has been provided with cover slot 11, play horizontal edge on the enclosing cover 1 of cover slot 11 correspondences and be provided with cue mark 12, in the time of need to opening enclosing cover 1, only need to insert the gap between enclosing cover 1 and roadbed 5 from the position of enclosing cover 1 edge cue mark 12 correspondences with instrument, can easily enclosing cover 1 be levered up; Described inner cap 2 is provided with covered hole 23, during dismounting inner cap 2, only need after removing lug 21 screws 4 of inner cap 2, by rising of special use, cover in instrument insertion covered hole 23, inner cap 2 can be mentioned and is opened.
Described inner cap 2 and enclosing cover 1 are composite material and make, because plane on inner cap 2 is concordant with the upper plane of the ring-shaped step 31 of base 3, when enclosing cover 1 covers on ring-shaped step 31, inner cap 2 has also played to enclosing cover 1 effect of supporting, so enclosing cover 1 can be made thinlyyer, to reach the effect of saving material.In addition, also on enclosing cover 1 surface, be provided with convex epirelief, play anti-skidding effect.
Described lug 21 is at least 3, periphery along inner cap 2 is uniformly distributed, when this manhole cover structure is for can bear the well head of larger internal pressure time, can be by increasing the quantity of inner cap 2 upper lug 21, and increase the bearing capacity that screw 4 quantity on each lug 21 strengthen inner cap 2.
