Abstract
The utility model relates to a high-strength lifting opening well cover for access openings of drainage and underground pipelines. The utility model aims to solve the problem that the provided well cover should have the characteristics of high lifting opening strength and difficult damages. The provided technical scheme is that: the lower ends of the peripheral edges of a plane of the high-strength lifting opening well cover are provided with downward protruding supporting ribs which are internally embedded with reinforcing frames; the bottom surface of the plane of the well cover is provided with a plurality of downward protruding reinforcing ribs which are staggered with one another, and the reinforcing frames are also embedded in the reinforcing ribs; and the well cover is also provided with two lifting openings. The high-strength lifting opening well cover is characterized in that the thickness of the lifting openings is consistent with that of the supporting ribs of the well cover. The horizontal projection of the well cover is rectangular or round. The lifting openings are centrosymmetrical.
Description
Technical field
The utility model relates to a kind of well lid, is specially a kind of high strength that is used for draining, underground pipeline access hole and lifts a mouthful well lid.
Background technology
Along with economy, fast development of society, the pipeline that underground is laid is more and more, and the quantity of various manholes is also increasing always on the road, comprises the manhole of drainage system, gas flue, and the manhole of equipment such as telecommunication line and electrical cable.The well lid that common composite material is made, it is smaller that it lifts mouthful thickness, identical with topping (well lid plane) thickness of well lid; In the middle of construction, because minority constructor's operation is lack of standardization, prize well lid with spade, lifting of general well lid mouthful is easy to cause damage, not only influence the outward appearance on well lid surface, and become stress and concentrate part; After passing vehicle rolls for a long time or repeatedly, make well lid crackle occur from lifting mouth, bring potential safety hazard to Pedestrians and vehicles.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of well lid is provided, and this well lid should have higher, the survivable characteristics of mouthful intensity that lift.
The technical scheme that the utility model provides is: high strength lifts a mouthful well lid, the surrounding on its well lid plane is shaped on the outstanding and inner brace rod that strengthens frame that is embedded with downwards along the lower end, the bottom surface on described well lid plane is shaped on some outstanding and interlaced reinforcing ribs downwards, also is embedded with the enhancing frame in the reinforcing rib; Also be provided with two on the well lid and lift mouth; The consistency of thickness that it is characterized in that the brace rod position of described thickness that lifts the oral area position and well lid.
The horizontal projection of described well lid is rectangle or circle.
The described mouth that lifts is about the center symmetry.
The beneficial effects of the utility model are: because mouthful thickness that lifts of well lid obtains strengthening, the well lid bottom lifts mouthful area at place and strengthens, and its intensity is strengthened, and lifts mouthful to be not easy to be destroyed by crowbar when opening well lid; And then making the significant prolongation in application life, use cost is able to obvious decline.

Fig. 2 is the B portion structure for amplifying schematic diagram among Fig. 1.
Fig. 3 is a plan structure schematic diagram of the present utility model.
Fig. 4 is the structural representation of looking up of the present utility model.
The specific embodiment
As shown in the figure, high strength lifts a mouthful well lid, and the surrounding on its well lid plane 1 is shaped on down outstanding brace rod 5 along 5, is embedded with in the brace rod 5 to strengthen frame 6; The bottom surface on well lid plane also is shaped on some outstanding and crossing reinforcing ribs 2 downwards, and the inside of reinforcing rib 2 is embedded with and strengthens frame 3 (just diameter is different with strengthening frame 6 to strengthen frame 2, and its material is identical, generally adopts reinforcing bar).Also be provided with two on the well lid and lift mouthfuls 4 (generally should about the center symmetry); The consistency of thickness (be about well lid planar thickness about 2 times) that it is characterized in that reinforcing rib 2 positions of described thickness that lifts mouthful 4 positions and well lid.
Further, the thickness at described reinforcing rib 2 positions and the consistency of thickness at reinforcing rib 5 positions.
The horizontal projection of described well lid is rectangle or circle.
Described well lid main body is filled by the composite material compacting.
The manufacturing process of this moulded well covers is: earlier reinforcing rib is put into die cavity, add a certain amount of composite material then, the demoulding after high temperature (140 ℃-160 ℃) mold pressing promptly obtains required well lid.
Because the oral area position that lifts of well lid obtains thickening, its intensity is improved, thereby is difficult for destroyed.
Described composite material is by reinforcing material (glass fiber or reinforcing bar), unsaturated-resin, low shrinkage additive, and filler and various auxiliary agent are formed; It is the conventional material of making well lid.
Claims (3)
1. high strength lifts a mouthful well lid, and the surrounding on its well lid plane (1) is shaped on outstanding downwards along the lower end and inside is embedded with the brace rod (5) that strengthens frame (6); The bottom surface on described well lid plane also is shaped on some outstanding and interlaced reinforcing ribs (2) downwards, also is embedded with in the reinforcing rib to strengthen frame (3); Also be provided with two on the well lid and lift mouthful (4); The consistency of thickness that it is characterized in that reinforcing rib (5) position of described thickness that lifts mouthful (4) position and well lid.
2. high strength according to claim 1 lifts a mouthful well lid, and the horizontal projection that it is characterized in that described well lid is rectangle or circle.
3. high strength according to claim 1 and 2 lifts a mouthful well lid, it is characterized in that described lift mouthful (4) are about the center symmetry.
