Description
Technical field
The utility model belongs to urban road facility, and the maintenance that relates in particular to plumbing on the urban road, coal gas, cable, optical cable and heating etc. is covered with inspection shaft.
Background technology
Urban construction is stamped multiple product with inspection shaft, but equal defectiveness.The stolen incident of casting iron well lid happens occasionally, and compound resin well cover is because deadweight is taken up badly broken when the cement concrete well lid uses easily by automobile.In recent years, the steel fiber concrete well lid is heavier with its deadweight, and recovery value is low, and advantage such as firm and durable substituted above product, but still has situation stolen and that be dropped, particularly shows manhole covers such as case, water valve case, must properly settle this type of problem.
Summary of the invention
At above-mentioned deficiency of the prior art, the purpose of this utility model provides a kind of steel fiber concrete anti-stealing manhole cover, and it wears pin together with well lid and well seat, thereby has solved the antitheft problem of well lid, and durable in use.
The purpose of this utility model is achieved in that this steel fiber concrete anti-stealing manhole cover main body is steel fiber concrete and housing thereof, and that profile has is square, rectangle and circle, described well lid be provided with one to two can with the pin hole 4 of well seat pin-connect.The edge of described well lid is provided with the steel plate housing 5 that is connected with inner reinforcing bar 6.Well lid is provided with the plug housing 9 of protrusion when the well lid profile is circle.For antitheft well lid can be provided with buckle structure on the opposite side well lid relative with pin hole, this buckle structure adopts any scheme of the prior art all can.
The utility model is reasonable in design, and technical scheme is simple and easy, does not increase cost, does not increase equipment, and is convenient for production, can reach the anti-purpose that abandons of manhole cover anti-theft, is worthy of popularization.
