Description

A kind of town road with inspection shaft

Technical field

The utility model relates to a kind of town road, specifically a kind of town road with inspection shaft.

Background technology

Road is divided into common road and town road, as speedway etc. do not need to arrange inspection shaft, protective guard, greenbelt belong to common road, need to carry out blowdown, protection, greening be generally town road, town road is administered by municipal administration.

Inspection shaft is the discharge structure on town road, and its top has inspection well cover, and existing inspection well cover comprises lid and outer ring, lid is located in outer ring, lid is provided with leaking hole and anti-skidding cross pattern, on lid, is generally also printed on " municipal administration " printed words simultaneously, shows its manager's identity.

The existing town road with inspection shaft in use Problems existing is: the junction of road surface and outer ring is very easy to damaged, due at vehicle, under the spreading of pedestrian, outer ring can be shaken, and because easily breaking in a little junction, rainwater easily inclines again erosion here, like this just as easy as rolling off a log depression, the damage causing road surface, inspection shaft place, because vehicle has had drop through out-of-date, vehicle is easily beated, and outer ring and inspection well cover are also easily damaged.

Owing to there is above-mentioned technical problem in prior art, impact uses, and therefore must improve.

Summary of the invention

The purpose of this utility model is: provide the junction of a kind of road surface and outer ring to be not easy the damaged town road with inspection shaft.

Scheme of the present utility model is: a kind of town road with inspection shaft, comprise by the inspection shaft of the thorough one-tenth of fragment of brick, inspection shaft both sides have dirt bed, dirt bed is higher than described inspection shaft, it is pavement concrete layer above dirt bed, bitumen layer above pavement concrete layer, described inspection shaft entrance is provided with ring bodies, ring bodies both sides are integrally formed with horizontal loop, on the ring bodies mouth of pipe, cover has outer shroud, it is inspection well cover inside described outer shroud, described ring bodies inwall has flange collar, described inspection well cover is supported in described flange collar, it is characterized in that: also comprise steel fibrous concrete layer and elastic concrete layer, area filling between inspection shaft and dirt bed and below horizontal loop has described steel fibrous concrete layer, area filling between pavement concrete layer and outer shroud and between pavement concrete layer and horizontal loop has described elastic concrete layer.

As preferably:

The position that described ring bodies inwall is positioned at below flange collar is provided with screen pack.

The utility model beneficial effect is compared with prior art: elastic concrete layer has firm in structure compared with ordinary concrete layer, the feature of good waterproof performance, the most important thing is that elastic concrete layer has elasticity, certain deformation can be produced when stressed, its setting just can solve the problems of the prior art, when under the spreading of traffic, outer ring haves no alternative but shake occurs, elastic concrete layer can do corresponding deformation thereupon, absorb this external force, prevent the generation slight crack that bursts apart, can prevent rainwater from attacking simultaneously, breakage is not easy in the junction of road surface and outer ring, be not easy produce depression and form drop, vehicle is beated through out-of-date being not easy, outer ring and inspection well cover is made also to be not easy to damage.Area filling between inspection shaft and dirt bed and below horizontal loop has described steel fibrous concrete layer, steel fibrous concrete layer has good intensity, the regional structure of filling can be made more firm, make ring bodies more firm, steel fibrous concrete layer relative resilient layer of concrete price is lower simultaneously, escapable cost.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for manual, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:

Fig. 1 is the structural representation that embodiment 1 has the town road of inspection shaft;

Fig. 2 is the structural representation that embodiment 1 has inspection well cover, outer ring and ring bodies.

Detailed description of the invention

Below by embodiment, the utility model will be further described by reference to the accompanying drawings.

Embodiment 1:

As Fig. 1, shown in 2, the town road with inspection shaft described by the present embodiment, comprise by the inspection shaft 1 of the thorough one-tenth of fragment of brick, inspection shaft 1 both sides have dirt bed 2, dirt bed 2 is higher than described inspection shaft 1, it is pavement concrete layer 3 above dirt bed 2, it is bitumen layer 4 above pavement concrete layer 3, described inspection shaft 1 entrance is provided with ring bodies 5, ring bodies 5 both sides are integrally formed with horizontal loop 6, on ring bodies 5 mouth of pipe, cover has outer shroud 7, be inspection well cover 8 inside described outer shroud 7, described ring bodies 5 inwall has flange collar 9, described inspection well cover 8 is supported in described flange collar 9, it is characterized in that: also comprise steel fibrous concrete layer 10 and elastic concrete layer 11, area filling between inspection shaft 1 and dirt bed 2 and below horizontal loop 6 has described steel fibrous concrete layer 10, area filling between pavement concrete layer 3 and outer shroud 7 and between pavement concrete layer 3 and horizontal loop 6 has described elastic concrete layer 11.The described ring bodies 5 inwall position be positioned at below flange collar 9 is provided with screen pack 12.

Ring bodies 5 is with its special structure; make it can obtain firm support after having constructed; mainly its underpart can insert in inspection shaft obtain spacing; its horizontal loop 6; can imbed in both sides steel fibrous concrete layer 10 and elastic concrete layer 11 and effectively be fixed; ring bodies 5 can form strong support to outer shroud 7; described ring bodies 5 inwall has flange collar 9; inspection well cover 8 is supported in described flange collar 9; inspection well cover 8 not only obtains the protection of peripheral outer shroud 7; the support of flange collar of having got back 9, result of use is better.Screen pack 12 filtering can enter the foreign material of inspection shaft, and prevent blocking, significantly, screen pack 12 can not be arranged.

The advantage with the town road of inspection shaft described by the present embodiment is: elastic concrete layer 11 has firm in structure compared with ordinary concrete layer, the feature of good waterproof performance, the most important thing is that elastic concrete layer 11 has elasticity, certain deformation can be produced when stressed, its setting just can solve the problems of the prior art, when under the spreading of traffic, outer ring haves no alternative but shake occurs, elastic concrete layer 11 can do corresponding deformation thereupon, absorb this external force, prevent the generation slight crack that bursts apart, can prevent rainwater from attacking simultaneously, breakage is not easy in the junction of road surface and outer ring, be not easy produce depression and form drop, vehicle is beated through out-of-date being not easy, outer ring and inspection well cover is made also to be not easy to damage.Area filling between inspection shaft 1 and dirt bed 2 and below horizontal loop 6 has described steel fibrous concrete layer 10, steel fibrous concrete layer 10 has good intensity, the regional structure of filling can be made more firm, make ring bodies 5 more firm, steel fibrous concrete layer 10 relative resilient layer of concrete 11 price is lower simultaneously, escapable cost.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
