The utility model relates to a kind of high-strength safe antitheft combined manhole cover, its structure is to be connected to central post in the Shell Plate of round box shape, on described central post, be connected to the enhancing floor of radial distribution, the outer of described enhancing floor and base and described Shell Plate link together, at the top of described Shell Plate, be provided with the keel stiffening ring being comprised of some rings, described keel stiffening ring is fixed together by connecting rod and described Shell Plate; The inner space of described Shell Plate is filled up and is paved by nonmetal inserts.The utility model compressive strength is high, and bearing capacity is large, to breakage, also can use pitch stone to repair, long service life, and cost is low, safe and reliable, the problem that efficiently solve easily fragmentation of cement well lid, causes peril to occur.
Description
Technical field
The utility model relates to a kind of overburden of manhole shaft, specifically a kind of high-strength safe antitheft combined manhole cover.
Background technology
For solving often stolen problem of steel well lid, a lot of places have particularly generally adopted cement well lid to add a cover on the well head of various manholes or lower well on the road of counties and districts rural.Due to the intensity of cement well lid relatively a little less than, after repeatedly the rolling of large-tonnage haulage vehicle, often occur brokenly, make various manholes or lower well on highway open wide top mouthful, cause various perils.
Utility model content
The purpose of this utility model is just to provide a kind of high-strength safe antitheft combined manhole cover, to solve the cement well lid problem that easily broken, initiation potential accident occurs.
The utility model is achieved in that a kind of high-strength safe antitheft combined manhole cover, in the Shell Plate of round box shape, be connected to central post, on described central post, be connected to the enhancing floor of radial distribution, the outer of described enhancing floor and base and described Shell Plate link together, at the top of described Shell Plate, be provided with the keel stiffening ring being comprised of some rings, described keel stiffening ring is fixed together by connecting rod and described Shell Plate; The inner space of described Shell Plate is filled up and is paved by nonmetal inserts.
The utility model utilizes Shell Plate to carry nonmetal inserts, utilizes enhancing floor and keel stiffening ring as the intensive aspect in nonmetal inserts, has improved thus the bulk strength of well lid.
The height of described central post is lower than the height of described Shell Plate, and arranging of described keel stiffening ring is highly concordant with the end face of described central post.Can make like this well lid end face be paved with by nonmetal inserts, prevent that central post etc. from exposing, and presses against bad doughnut.
Described enhancing floor is right-angled trapezium, and the link of itself and described central post is higher than the link with described Shell Plate side edge.
Edge, outside at described Shell Plate is provided with for being socketed the connecting ring of walling crib bearing pin, and well lid and walling crib are linked together, and prevents loss.
On the side edge of described Shell Plate, be provided with latch, described latch and described connecting ring are positioned at the two ends of a diameter line of described Shell Plate.Improving latch can be fixed on well lid in walling crib, avoids flooding or rises in well and wash well lid open when raining heavyly.
Described Shell Plate is cylindrical or truncated cone-shaped.Cylinder blanket plate forms conventional well lid, and truncated cone-shaped Shell Plate forms frustum well lid, and can there be larger laminating contact surface on the latter and walling crib and road surface, arranges more stablely, also can prevent the tenesmus of well lid and walling crib, and can effectively avoid the generation of well lid pressure situation.
The utility model compressive strength is high, and bearing capacity is large, to breakage, also can use pitch stone to repair, long service life, and cost is low, safe and reliable, the problem that efficiently solve easily fragmentation of cement well lid, causes peril to occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top surface structure schematic diagram of Fig. 1.
In figure: 1, Shell Plate, 2, strengthen floor, 3, central post, 4, keel stiffening ring, 5, connect cross bar, 6, connecting ring, 7, bearing pin, 8, connecting upright pole, 9, latch.
The specific embodiment
As shown in Figure 1 and Figure 2, Shell Plate 1 is to strike out round box shape (to make cylindrical well lid) with steel plate or galvanized sheet, can be also the disc that opening is larger (to make truncated cone-shaped well lid); At the center of Shell Plate 1, be welded with central post 3, the height of central post 3 is lower than the plane of the opening of Shell Plate 1.On central post 3, be welded with some enhancing floors 2 that radially distribute, strengthening floor 2 is to be cut into band steel, and shape can be rectangle or right-angled trapezium.For the enhancing floor 2 of right-angled trapezium, its set-up mode is that the one end being connected with central post 3 exceeds with Shell Plate 1 side along the one end being connected.Strengthen the outer of floor 2 and inner bottom surface and the inside wall that base is welded on respectively Shell Plate 1.
At the top of Shell Plate 1, be provided with keel stiffening ring 4, keel stiffening ring 4 is plane bodies of a grate type being welded to form by connecting rod by the some reinforcing bar rings that differ in size.Together with keel stiffening ring 4 is welded and fixed with inner bottom surface with the inside wall of Shell Plate 1 by some connecting rods.Connecting rod comprises connection cross bar 5 and connecting upright pole 8.Arranging of keel stiffening ring 4 is highly concordant with the end face of central post 3.
The inner space of Shell Plate 1 is to be filled up and paved by nonmetal inserts.Described nonmetal inserts can be the materials such as concrete, steel fibre or glass fiber reinforced plastics composite material, like this, for the damaged part of local damage well lid, can repair with pitch stone, to avoid the integral body of local damage well lid to scrap.
In Fig. 1, on the edge, right-hand member outside of Shell Plate 1, be provided with connecting ring 6, accordingly, be provided with bearing pin 7 in walling crib, bearing pin 7, by socket connection ring 6, links together well lid and walling crib.On the left end side edge of Shell Plate 1, latch 9 can be set, latch 9 and connecting ring 6 are positioned at the two ends of a diameter line of Shell Plate 1.Latch 9 is plugged in walling crib, can prevent that walling crib from being risen and washing open in well, guarantees driving and the pedestrains safety in ponding section.
At the top of Shell Plate 1 mouth, a guard ring can be set, the outer of guard ring is welded on the top on Shell Plate 1 edge, inner side, to improve the intensity of well lid.On well lid, also have air-vent, air-vent can be made with special-shaped iron pipe.
