Abstract
A high-strength supporter-free inspection well cover comprises a cover body with marginal slant surface inclining outwards to form a slant supporter surface. The marginal surface of the cover body is a slant supporter surface, so that the well cover can support the inspection well by configuring the inspection well opening to be slant. The utility model has the advantages of complete contact, reasonable bearing structure, high overall strength, no vibration and noise, simplified construction of inspection well opening, and low cost.
Description
Technical field: the utility model relates to a kind of inspection shaft lid.
Background technology: but general inspection shaft lid all will be placed on cooperation ability capping inspection shaft on the corresponding bearing.Like this must be when construction at the pre-buried bearing in inspection shaft mouth position, efficiency of construction is low, and whole cost increases.And the edge surface force structure of general inspection shaft lid is unreasonable, and it is unreliable to contact, and presses the out-of-date easy vibration sound at vehicle, and bulk strength is also relatively poor, is easy to breakage, changes and safeguards inconvenience.
Summary of the invention: at the deficiencies in the prior art, the utility model provides the rational high strength of a kind of force structure not have an inspection shaft lid.
It is the inclined plane that high strength of the present utility model does not have a side edge surface of the lid of inspection shaft lid, and top is outwards toppled over and constituted the bearing diagonal face.
The side edge surface of lid of the present utility model is the bearing diagonal face, only needs corresponding inspection shaft mouth also bevel, promptly can secure support cooperate, full contact, force structure is reasonable, has improved bulk strength, be not easy to produce the vibration sound, and simplified manhole constructing, reduced cost.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment;
Fig. 2 is the vertical view of Fig. 1.
Embodiment: as shown in the figure, the side edge surface of lid 1 is the inclined plane, and top is outwards toppled over and constituted the bearing diagonal face.In the road construction, only need the inspection shaft mouth is made corresponding inclined-plane, can fully support cooperation, need not pre-buried bearing, reduce construction cost with lid 1.
Present embodiment also is provided with several through holes 2 on the end face of lid 1, be convenient to draining like this.Lid 1 can be made as circle, different shape such as square, can also use various material manufacturings, if use concrete, also can establish reinforcing rib 3 in lid 1, and intensity is higher like this, uses more reliable.
Claims (3)
1, a kind of high strength does not have an inspection shaft lid, comprises lid, and it is characterized by: the side edge surface of lid (1) is the inclined plane, and top is outwards toppled over and constituted the bearing diagonal face.
2, high strength according to claim 1 does not have an inspection shaft lid, it is characterized by: also be provided with several through holes (2) on the end face of lid (1).
3, high strength according to claim 1 and 2 does not have an inspection shaft lid, it is characterized by: be provided with reinforcing rib (3) in the lid (1).
