The specific embodiment
A kind of structure improved well lid as shown in Figure 1, 2, comprises well lid body 10, enhancement Layer 12 and frp layer 14.Well lid body 10 is made up of first metal tube 16 several and that row of horizontal is affixed; Enhancement Layer 12 is made up of second metal tube 18 several and that row of horizontal is affixed; All be filled with concrete 20 in each first metal tube 16, each second metal tube 18; Enhancement Layer 12 is fixed in well lid body 10 downsides.Frp layer 14 is attached to well lid body 10 upper sides; The plane is a horizontal plane on the frp layer 14.
Embodiment of the present utility model is that the cross section with well lid is that square is an example, but is not that square exceeds with the cross section of well lid, and other cross sections as well lid are that circle, regular hexagon, polygon-octagonal also are applicable to the utility model.
The structure of each first metal tube 16 and each second metal tube 20 is identical; The cross section of each first metal tube 16 and each second metal tube 20 is square.
Enhancement Layer 12 is fixed in well lid body 10 downsides, and several second metal tubes 20 side by side are fixed in several first metal tube, 16 downsides side by side; Described several second metal tube 20 is side by side arranged with several first metal tube, 16 square crossings side by side.
Frp layer 14 is fixed in several first metal tube, 16 upper sides side by side by bonding or frame for movement or other mode.The cross section of the cross section of frp layer 14 and well lid body 10 and identical.The upper side of frp layer 14 can be provided with decorative layer.
Behind affixed well lid body 10 and the enhancement Layer 12, before the fill concrete 14, can be as required and several first metal tube 16 and several side by side outer peripheral edges of second metal tube 20 side by side are processed as the structure that cooperates with the well seat.
Well lid body 10, several first metal tubes 16 side by side, the corresponding side surface 22,22 between wherein every adjacent two first metal tubes 16 is ' by seamless affixed of welding or bonding and affixed one-tenth.
Enhancement Layer 12, several second metal tubes 20 side by side, the corresponding side surface 24,24 between wherein every adjacent two second metal tubes 20 is ' by seamless affixed of welding or bonding and affixed one-tenth.
Affixed between several first metal tubes 16 side by side is seamless affixed, and affixed between several second metal tubes 20 side by side is seamless affixed, so whole well lid is to seal the not well lid of porous.
Well lid body 10, enhancement Layer 12 outer peripheral edges can set firmly intensity, the protection well lid of angle steel to strengthen well lid as required; Or plug is set at the mouth of pipe of several first metal tubes 16, several second metal tubes 20.
The side and the bottom surface of well lid are provided with coating, and coating connects and constitute the skin of a sealing with frp layer 14.Coating may be selected to be resin bed, frp layer, epoxy resin, rustproof paint.Coating plays the effect that prevents that the metal tube in the well lid from getting rusty, i.e. protective effect; Also play the effect of decoration.
Described concrete 20 can be general cement and also can be macromolecule concrete, resin concrete, special cement etc.
As shown in Figure 3, the well seat that cooperates with embodiment one of the present utility model has circular well head 26 and recessed connection seat 28, and connection seat 28 is square, and the center of connection seat 28 overlaps with the center of the circle of well head 26.Connection seat 28 matches with well lid, and its cross section is identical with the cross section of well lid.Both to have cooperated area be cross section poor of the cross section of well lid and well head because the relative contact between well lid and the connection seat 28 amasss, so contact area is big, and the linking intensity height.
Another preferred embodiment of the present utility model, as shown in Figure 4, described several second metal tubes 20 side by side are vertically staggered with several first metal tubes 16 side by side, have both formed honeycomb structure.The well lid both sides of this embodiment form ledge structure.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
