Abstract

An anti-inclination road well cover includes a cast iron well cover 1, a well platform 2, a pre-embedded frame 4 and a heightening ring 3, the utility model is characterized in that the inside of the well cover 1 is provided with a curved convex ring; an internal ring groove and an external extensive edge a are arranged on a vertical ring of the well platform 2, the lower edge of the vertical ring is an external spreading ring b; one side of the heightening ring 3 is provided with a ring groove and an external flange, and the other side is provided with an overlapping convex ring platform. The convex ring of the well cover 1 or the convex ring platform of the heightening ring 3 is arranged on the well platform 2 or the ring groove of the heightening ring 3, a slit of the pre-embedded frame 4 is locked on the external spreading ring b of the well platform 2, and a main body is built in a brick wall. The designed well cover is fallen into a well platform groove, the non-turning cover and the pre-embedded frame which is similar with a supporting leg can provide stronger supporting force to the well platform, therefore, the well cover can not be pressed to be inclined. When in road renovation, another heightening ring is arranged on the well platform to realize that the well cover is at the same level with the new road.

Description

Anti-askew road manhole
Technical field the utility model relates to public transit facility, and the following well in the road, gasser, heating wells, telecommunications well etc. are a kind ofly prevented partially, the anti-well lid that turns over.
But the depression or the well lid of deflection are arranged on the common road of background technology, and vehicle was pressed with chuckleing the thump thump, and promptly influencing the road surface attractive in appearance is again potential safety hazard, this old problem in the municipal engineering.The urban road improvement project is increased, yet when raising after the pavement recapping, the road manhole of existing structure becomes the depression position, influences the smooth effect on road surface, needs the rebuilding well head, wastes time and energy, and strengthens engineering cost.The daily road surface position of easy damage also is a well lid.Cast iron well head circle in the past is to be placed on the brick conical well head, well head is less because the down-hole face is big, will form hanging shape when therefore up laying bricks, and the immense pressure that the brick exactly will bear road vehicles, the compressive strength of brick is again very limited, so raised platform around a well subsides, well lid is easy to be pressed askew.In addition, the height of the upright circle of existing raised platform around a well is less than 10 centimeters, edge, lower edge that only will be narrower is imbedded under the pitch on road surface, when car constantly rolled and the temperature in four seasons influence, pitch cracking around the well head circle, loosening, also can make the askew heresy of well lid, renovate, well lid is damaged, easilier cause vehicular traffic even pedestrian injured.
Novel content the purpose of this utility model provides a kind of anti-askew road manhole, comprises well lid 1, raised platform around a well 2 and the ring extension 3 of cast iron, it is characterized in that there is the protruding circle that is one well lid 1 inboard; The inner groove of promising one and extension are along a on the upright circle of raised platform around a well 2, and the Li Quan lower edge is abduction ring b; Ring extension 3 is that a side has annular groove and outward flange, and opposite side has the bulge loop platform of stack; Be approximate rectangular plate for pre-buried 4, wide end, hypotenuse side have the rectangle gap, and the straight flange side has a plurality of holes.The protruding circle of well lid 1 cooperates with the inner groove of raised platform around a well 2, also the bulge loop platform of ring extension 3 can be placed in the inner groove of raised platform around a well 2, and the protruding circle of well lid 1 places in the annular groove of ring extension 3; The abduction ring b of raised platform around a well 2 probes in pre-buried 4 the gap, builds in brickwork joint for pre-buried 4.
The design's well lid has flange to cooperate with the annular groove of raised platform around a well, can not renovate.The upright circle of raised platform around a well is outer two-layer extension edge, but placing of concrete therebetween, and and extension is along the last height that covers pitch to Li Quan upper edge and well lid again, strengthens and contacting of supercrust on every side.Particularly the design has increased the upright circle of raised platform around a well, and use concrete strengthening when installing, and so just reduced brick height, and the force part becomes firm, so has been pressed askew phenomenon with regard to well lid not occurring.When the renovation road surface,, just realized that well lid and new road surface maintain an equal level to adding a ring extension on the raised platform around a well in addition.Build for pre-buried 4 in brick wall, be equivalent to the pin of raised platform around a well, fixing and support force is stronger.

The specific embodiment
Prevent askew road manhole, comprise well lid 1, raised platform around a well 2, pre-buried 4 and the ring extension 3 of cast iron, it is characterized in that there is the protruding circle that is one well lid 1 inboard; The inner groove of promising one and extension are along a on the wall under the Li Quan upper edge of raised platform around a well 2, and the Li Quan lower edge is abduction ring b; In the upright ring recess of raised platform around a well 2 to upper edge height h equate with the height of well lid 1, its inner groove width and highly equating with the size of the protruding circle of well lid 1; The outer stiles of the upright circle of raised platform around a well 2 are rectangular along a and abduction ring b with extension, raised platform around a well 2 stand enclose abduction ring b greater than extension along a.Ring extension 3 is that a side has annular groove and outward flange, and opposite side has the bulge loop platform, is the not isometrical concentric ring platform of stack, and the width and the height of its path bulge loop platform equate with the protruding circle of well lid 1 and the annular groove size of raised platform around a well 2; The outward flange size of its maximum diameter equates with the size of raised platform around a well 2 Li Quan upper edges.Be approximate rectangle for pre-buried 4, one bar broadside is less than another broadside, and thicker end is not more than the broadside of brick; The long limit of one bar is a hypotenuse, in thicker end, hypotenuse side the rectangle gap is arranged, and longitudinally leaves a plurality of holes in the straight flange side.
Construction is when laying bricks, and pre-buried 4 three are stood in the tubular brick wall equally spacedly, while laying bricks one section reinforcing bar vertically passed pre-buried 4 hole, and reinforcing bar is stayed in the concrete seam of brick, and pre-buried 4 gap is stuck on the abduction ring b of raised platform around a well 2.The protruding circle of well lid 1 cooperates with the inner groove of raised platform around a well 2, and it is stiff that well lid is fallen in the groove of raised platform around a well.But raised platform around a well 2 extensions are along high strength coagulum such as fill concrete also between the height between a and the abduction ring b, extension above a topped pitch to Li Quan upper edge height.When pavement patching is increased, need not move raised platform around a well 2, only need the protruding circle of ring extension 3 is placed in the inner groove of raised platform around a well 2, the protruding circle of well lid 1 places in the annular groove of ring extension 3 and gets final product.The height of ring extension 3 can be made different sizes such as 30mm, 50mm, needs with the pavement recapping that is suitable in various degree.
The design anti-turn over well lid and raised platform around a well, ring extension structure, also can make rectangles such as square or rectangle as required.
