Abstract
The utility model provides a composite material annular rib reinforcement well cover, the reverse of which consists of an annular rib 1, a rib bar 2, a side rib 4 and an inner rib 3. The rib bar 2 is designed to be 4-8 pieces, the two ends of the rib bar are connected with the side rib 4 and the inner rib 3. The annular rib 1 is arranged between the side rib 4 and the inner rib 3, each part of the annular rib 1 between the rib bars 2 can be designed to be a curve rib or a straight rib. According to the different force sustaining conditions, the annular rib 1 between the side rib 4 and the inner rib 3 can be designed to be 1-5 pieces. The utility model has strong sustaining capability, can cause the well cover to be more firm, and cannot be crushed by heavy truck.
Description
Affiliated technical field
The utility model is a kind of well lid design improvement technology, can make well lid more firm, and heavy truck is difficult for rolling fragmentation.
Background technology
At present, most of well lid structure is to be made of the rib of ining succession under well lid face and the well lid face.The rib major part of ining succession under the well lid face is " well " shape shape, plays the effect of bracing reinforcement well lid.But urban road is bearing vehicle flowrate height, pressure that the vehicle tonnage is big, so the various well lids that use on the road all exist the phenomenon that holding capacity does not reach requirement at present, well lid often occurs and damages by pressure, directly threatens pedestrian's life security.
Summary of the invention
Do not reach the deficiency of requirement in order to overcome existing well lid holding capacity, the utility model is transformed on existing manhole base, can make well lid more firm, and heavy truck is difficult for rolling fragmentation.
The technical scheme that its technical problem that solves the utility model adopts is: at the back side of well lid, be made up of annular rib, rib, limit muscle, interior muscle, rib is 4 to 8, and its two links to each other with interior muscle with the limit muscle, 5 centimetres to 40 centimetres of interior muscle diameters.Annular rib is between limit muscle and interior muscle, and the part of annular rib between rib is bent muscle or straight muscle, and annular rib has 1 to 5 between limit muscle and interior muscle.
The beneficial effects of the utility model are, existing well lid has been carried out technical transformation, and it has the strong characteristics of ability to bear, can make well lid more firm, and heavy truck is difficult for rolling fragmentation.
Description of drawings
Fig. 1 is the vertical view of well lid back, and the book accompanying drawing is numbered 1 annular rib among the figure as an illustration, 2 ribs, 3. interior muscle, 4 limit muscle.
1 pair of the utility model embodiment of vertical view below in conjunction with the well lid back further specifies.
The specific embodiment
In the drawings, rib 2 is at the well lid back side, has 4 to 8, and its two links to each other with interior muscle 3 with limit muscle 4,5 centimetres to 40 centimetres of interior muscle 3 diameters.Wherein between limit, annular rib 1 seat muscle 4 and the interior muscle 3, the part of annular rib 1 between rib 2 is bent muscle or straight muscle, and annular rib 1 has 1 to 5 between limit muscle 4 and interior muscle 3.Therefore, the whole annular rib at the well lid back side can be circle or polygon, and annular rib, rib, its height of interior muscle and width are 2 centimetres to 40 centimetres and 1 centimetre to 20 centimetres.In manufacturing process, by different designing moulds, the integral body of producing once is finished.
