Abstract

The utility model discloses an anti-shock inspection shaft for a road sewer. An elastic buffer layer is arranged between the contact surfaces of a shaft cover and a shaft body of the anti-shock inspection shaft. The elastic buffer layer can be installed in a groove of the shaft cover or the shaft body, or arranged between the shaft cover or the shaft body in a loopping or sheathing type, etc. The anti-shock inspection shaft solves the problem that when vehicles run on the inspection shafts of the road, shocking noise is sent out, the inspection shaft body is sunk below the road surface for long-term impact because of having no shock resistance, the unevenness of the road surface is generated, and thus bigger shocking noise of vehicles is brought. Thus, the utility model has extremely actual significance for the road construction and maintenance, and reducing the city noise.

Description

Shockproof inspection shaft

The utility model relates to a kind of inspection shaft that is used for road dredging sewer mouth, particularly a kind of shockproof inspection shaft.

At present all there is the inspection shaft road surface of sinking in the inspection shaft in urban road, and vehicle covers at inspection shaft that the inspection shaft lid sends and the sound of well bore bump and the noise that vehicle shakes when crossing, and brings pollution to urban environment.

The purpose of this utility model is a kind of elimination impact noise that designs in order to solve above-mentioned technical deficiency, slows down the shockproof inspection shaft on the sagging road surface of inspection shaft.

In order to achieve the above object, the shockproof inspection shaft that the utility model is designed, comprise well bore and well lid, accompany elastic cord breaker between the contact surface of well bore and well lid, the material of this elastic cord breaker can be plastics, nylon etc., as the polyvinyl fluoride material, also can be rubber or sandwich the reinforcing rib material in rubber, as other materials such as wire or linen threads, the shape of this elastic cord breaker can be a kind of

The shape cover will

Shape is enclosed within outside the well lid, is placed on then on the well bore mouth.In order to save material, reduce production costs, this elastic cord breaker can also be a kind of

Shape circle or shape circle, and should

Shape circle or shape circle wrap on the well lid periphery, make between the contact surface of well lid and well bore and all accompany elastic cord breaker.In order further to reduce cost, be convenient to suitability for industrialized production, this elastic cord breaker also can be a kind of elastic ring, this elastic ring can be as belt pulley, be arranged on it in well lid periphery side channel and at the bottom of the well lid with groove that the well bore mouth contacts in; Also can be arranged in the well lid periphery side channel and well bore suitable for reading with the groove that contacts at the bottom of the well lid in.Elastic ring at the bottom of embedding the suitable for reading or well lid of well bore in the groove can use the polytetrafluoroethylene (PTFE) nylon material, and the elastic ring in embedding the peripheral side channel of well lid can be with the bigger rubber of elastic strength.

The shockproof inspection shaft that the utility model obtained, owing on the contact surface between inspection shaft well bore and the well lid, be provided with elastic cord breaker, when making vehicle cross well lid, the bump of well lid and well bore has obtained buffering, suffered impact force when making well bore avoid bump, thereby the vibrations when having slowed down the sagging speed of well bore and vehicle and crossing.Thereby reduced by bump and the noise pollution that produced of vibrations, road construction and maintenance and reduction city noise thereof have been produced positive effect.

Below in conjunction with accompanying drawing, the utility model is done progressive the description by embodiment.

Embodiment 1:

As shown in Figure 1, the shockproof inspection shaft that present embodiment is described is made up of well bore 1, well lid 2 and elastic cord breaker 3, and elastic cord breaker 3 is a kind of

The shape cover can select for use abrasive rubber to make, and elastic cord breaker 3 upwards is enclosed within outside the well lid 1 from the bottom of well lid 1, places then on the well bore 1, becomes complete shockproof inspection shaft.

Embodiment 2:

As shown in Figure 2, the shockproof inspection shaft that present embodiment is described is made up of well bore 1, well lid 2 and elastic cord breaker 3, and elastic cord breaker 3 is a kind of The shape circle,

The shape circle selects for use abrasive rubber to make, should The elastic cord breaker 3 of shape circle wraps on the periphery of well lid 2, places then on the well bore 1, becomes complete shockproof inspection shaft.

Embodiment 3:

As shown in Figure 3, the shockproof inspection shaft that present embodiment is described, form by well bore 1, well lid 2 and elastic cord breaker 3, elastic cord breaker 3 is a kind of shape circles, the elastic cord breaker 3 of this shape circle selects for use abrasive rubber to make, and embeds linen thread in rubber, and the elastic cord breaker 3 that this shape is enclosed wraps on the bottom side periphery of well lid 2, place then on the well bore 1, become complete shockproof inspection shaft.

Embodiment 4:

As Fig. 4, shown in Figure 5, the shockproof inspection shaft that present embodiment is described, form by well bore 1, well lid 2 and elastic cord breaker 3, elastic cord breaker 3 is a kind of O shape elastic rings, as shown in Figure 4, the elastic cord breaker 3 of O shape elastic ring is arranged in the side groove 4 and bottom groove 5 of well lid 1, covers then on well bore 1.As shown in Figure 5, in the groove 5 that the elastic cord breaker 3 of O shape elastic ring is arranged in the side groove 4 of well lid 1 and well bore is suitable for reading, placing then becomes complete shockproof inspection shaft on the well bore 1.
