The invention discloses a bearing platform type manhole cover assembly comprising a well seat (1), a manhole cover (4) and a bearing platform (3), ). Thewherein the manhole cover (4) is connected with the bearing platform (3) by using a fastener (5); the periphery of the manhole cover (4) is in a circular shape, the center of the manhole cover (4) is provided with a screw hole (9) and is also provided with a hoisting handle (11); and the middle of the reverse side of the manhole cover (4) is provided with a circular platform (7) with the screw hole (9) and is also provided with radiated reinforcing ribs (11); ). Thethe periphery of the bearing platform (3) is in a circular shape, the center of the bearing platform (3) is provided with the circular platform (7) with the screw hole (9) and is also provided with spokes (6); the bearing platform (3) is installed on the inner ring of the well seat (1); the manhole cover (4) is fixed on the bearing platform (3) through the fastener (5) and is embedded in the well seat (1) into a whole to form a manhole cover assembly; and the cross sections of the spokes of the bearing platform is in a shape like a Chinese character 'yi'in a straight line shape or a V shape or a double-V shape or a multi-V shape. In theThe invention, coordinates the manhole cover assembly and the traditional manhole barrel (2) are combined to form a bearing platform type manhole; . Comparedcompared with the existing traditional bearing platform type manhole, the bearing platform type manhole has the advantages of simplified structure, reduced manufacturing cost and convenient installation; , and the bearing platform type manhole can not only be applied used as a new manhole, but also be used for reforming old manholes.
Description
Technical field
The present invention relates to manhole, relate in particular to the manhole that is used for checking facilities such as underground pipeline, cable, optical cable, furthermore, relate to bearing platform type manhole cover.
Background technology
At present, the Chinese patent application part that relates to manhole and well lid thereof reaches thousands of.Most patented technologies are the well lids from structure and material improvement manhole.As CN00112189.8 " plumbing manhole cover, seat and production technology thereof ", CN00132052.1 " manhole cover made of composite material and well seat ", CN200310112674.2 " pipe type manhole ", CN03131811.8 " integral type pipe manhole " etc.But thoroughly do not solve the shortcoming that existing manhole exists yet.For this reason, the inventor had once developed novel bearing platform type manhole, and relevant patent has " bearing platform type safety manhole " No. 200510003298.2, and its advantage is durable, can ensure driving and pedestrian's safety.But this bearing platform type manhole mainly is divided into well base, pit shaft, well seat, walling crib, A font cushion cap and well lid, the supporting capacity of the A font cushion cap of this well lid is very strong, but the structure of whole manhole is comparatively complicated, cost is higher, existing well lid displacement, construction are comparatively bothered, relatively be applicable to newly-built manhole.
Summary of the invention
The purpose of this invention is to provide the bearing platform type manhole cover combination, can keep the advantage of existing bearing platform type manhole, can overcome the shortcoming of existing bearing platform type manhole again.
For achieving the above object, the bearing platform type manhole cover combination that the inventor provides only comprises well seat, well lid and cushion cap, and well lid is connected with securing member with cushion cap, is characterized in:
1. the periphery of well lid can be circle, square, rectangle or polygon, and the well lid front has center screw, also has lifting handles; The middle part of reverse side is the round platform that has screw, also has reinforcing rib radially;
2. the periphery of cushion cap is circular, and the center is a round platform that has screw, between circular periphery and the round platform spoke is arranged; The periphery of cushion cap is installed on the inner ring of well seat;
3. well lid is fixed on the cushion cap by securing member, and embeds the well seat, and well seat, well lid and cushion cap are linked to be integral body, forms the well lid combination.
The reinforcing rib of above-mentioned well lid is thicker by an end of periphery, and thinner by an end at center; Two lifting handles of well lid are symmetry arrangement.
The circular periphery of above-mentioned cushion cap and the spoke between the round platform are 4～16; The spoke cross section is an in-line, or is " V " shape, or is two " V " shapes, or is many " V " shape.
The well lid disappearance scribbles reflecting coating on the above-mentioned cushion cap, in case can be warned pedestrian and vehicle.
Adopt cascaded surface or inclined plane embedding between above-mentioned well lid and the well seat, install seal with elastometic washer additional.
Have space for maintenance and chock, pad bottom the above-mentioned well seat.
The material of above-mentioned well lid, cushion cap and well seat can adopt the commaterial among cast iron, iron and steel, glass fiber reinforced plastic, steel concrete, steel fibrous concrete, polypropylene fiber concrete, the polymer matrix composite to make.
The inventor points out, the reinforcing rib periphery that adopts is thick, the mode of intermediate thin, and two reinforcing ribs of symmetry form an arch, dome-shaped that makes progress of the common formation of all reinforcing ribs, help well lid pressure is dispersed to periphery, be similar to the stressed of arch bridge, vault.
The inventor points out that again cushion cap is the topping and the well lid bearing stratum of manhole inside; Cushion cap is used for supporting well lid, and gravity and vibration that well lid is born are delivered to the well body, alleviate the stressed amount of deflection of well lid.
During use, the well seat is fixed on the pit shaft, well lid and cushion cap are installed again, well lid is connected with cushion cap, make the well lid plane consistent with ground level with securing member; Well lid combination is cooperated with traditional manhole pit shaft, promptly is the bearing platform type manhole.
Bearing platform type manhole cover of the present invention combination because cushion cap with the stressed well seat that is distributed to of well lid, can reduce the pressure of vehicle to manhole cover, reduces vehicle and passes through the vibration that produced, thereby prolongs manhole cover application life; Cushion cap closely is connected with well lid, well lid be difficult for by the wheel pressure, be difficult for stolen; As the well lid disappearance takes place, because cushion cap has blocked well head, people and wheel can not fallen in the well.If manhole sinks or tilts, also overhaul easily, proofread and correct.Compare with existing bearing platform type safety manhole, designs simplification, cost reduces, and is easy for installation.Can be used for newly-built manhole, also can be used for transforming old manhole.
