Abstract
The utility model relates to an inspection well cover, in particular to a high-strength steel fiber inspection well cover, Aiming at providing a high-strength steel fiber inspection well cover which has the advantages of simple and reasonable structure, high punching-resistant strength, low noise and low production cost. The utility model adopts the technical scheme that the high-strength steel fiber inspection well cover comprises a support seat and a tubular inspection well cover covered on the support seat. The high-strength steel fiber inspection well cover is characterized in that the inspection well cover comprises an upper-layer cover body, a lower-layer cover body and a cover ring arranged between the upper-layer cover body and the lower-layer cover body, and the lower-layer cover body and the cover ring form an integral piece formed by molding an iron plate. By arranging the cover ring and the lower-layer cover body which are formed by the iron plate below the upper-layer cover body, the compression resistance and the bearing capacity of the well cover are enhanced, the service life is prolonged, and the well cover can be avoided from being crushed when a large quantity of vehicles pass by.
Description
Technical field
The utility model relates to a kind of inspection shaft lid, specifically is a kind of high-intensity steel fibre inspection shaft lid.
Background technology
Along with economy, fast development of society, various inspection shafts are more and more on the road, comprise the maintenance inspection shaft of drainage system, electrical cable, and the inspection shaft of equipment such as communication network and coal gas.Inspection shaft lid commonly used is made of Moveable lid body and the lining that is fixed on the road surface, and Moveable lid body can be opened or close, and identical smooth with the road surface, guarantees the unimpeded of pedestrian, vehicle.This type of inspection shaft lid is generally made by cast iron, have the strong characteristics of anti-impact force, but cast iron itself has higher economic value, often becomes the object that the undesirable steals; More particularly be positioned at the inspection shaft lid of remote position, often stolen and be difficult in time redistribute installation, constitute dangerous pedestrian and driving.In addition, because inspection shaft lid quality problems are damaged by pressure by vehicle, in time do not repair or change; Or open the draining of inspection shaft lid and forget and cover back that these do not cover or uncap forgets that situation about resetting again all constitutes danger to pedestrian or driving, often there is vehicle to be absorbed in inspection shaft or pedestrian and falls into accident generation in the well, cause everybody strong attention.Simultaneously castiron inspection shaft lid is in use also found, when motor vehicle passes through well lid, owing to do not have shock-absorbing capacity and well lid quality really up to the mark between well lid and the carrier base, carrier base is given in the impact force pressure transmission that dynamic load is produced easily, make carrier base and infrastructure suffer conquassation and breakage occur, also, consequently influence the living environment of surrounding resident with bigger noise.
At problem last time, people select for use a kind of inspection shaft lid of composite material to replace cast iron inspection shaft lid, characteristics such as that though the inspection shaft that composite material is made lid has is in light weight, technology simple, good looking appearance, cost of production are low, and the phenomenon of being stolen can not appear, but because its anti-impact presses hit intensity poor, use soon, defectives such as well lid fracture or breakage will occur; Simultaneously, when the vehicle KDT was crossed this inspection shaft lid, well lid also can start from carrier base, and hinders its normal use, and therefore such structure has influenced promoting the use of of it on certain program.
At present, also do not address the above problem better technical scheme.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of high-intensity steel fibre inspection shaft lid is provided, and that this inspection shaft lid should have is simple and reasonable, anti-impact pressure degree height, noise is little, cost of production is low characteristics.
The technical solution adopted in the utility model is: a kind of high-strength steel fibre inspection shaft lid, the tubular inspection shaft that comprises carrier base and be covered on the carrier base covers, it is characterized in that: described inspection shaft lid is formed by upper strata lid, lower floor's lid with around being arranged between the upper and lower layer lid decorative cover, and described lower floor lid and decorative cover are the integral piece of an iron plate moulding.By decorative cover and the lower floor's lid that is made of iron plate is set, thereby strengthen the crushing resistance and the bearing of well lid under the lid of upper strata, improved application life, avoided well lid conquassation well lid when a large amount of vehicles pass through.
Described inspection shaft lid is for columnar structured, and the lower floor's lid of inspection shaft lid and the thickness of decorative cover are 3～8 centimetres.
Be provided with one in the described inspection shaft lid through the steel member skeleton between the upper and lower layer lid, steel member skeleton is the integral piece that is welded into by integral plate and crisscross the channel-section steel that is distributed in this surface of steel plate.Satisfied the designing requirement of intensity of load, made that inspection shaft lid supporting capacity is strong, resistance to compression, tension, bending resistance, excellent in cushion effect promptly have robust characteristics.
Also be filled with cement or sandstone between the space of described steel member skeleton.
In the described inspection shaft lid also correspondence two latch grooves are set, correspondingly be arranged to right pinhole on the decorative cover of inspection shaft lid with on the carrier base sidewall, the steel dowel inserts pinhole and inspection shaft is covered fixedlys connected with carrier base.Have the latch of locking function by setting, reinforced the annexation between inspection shaft lid and the carrier base, prevent that the thing that the inspection shaft lid is stolen from taking place thereby further play.
Described upper strata lid is formed by concreting, and the external surface of upper strata lid is provided with anti-skidding, wear-resisting Argyle bar, increases the frictional force of upper strata lid, to reach current purpose of safety.
Described tubular inspection shaft covers and also is provided with two and lifts the hole, thereby brings great convenience for installing, safeguarding.
Described carrier base is logical up and down truncated cone-shaped structure of pushing up, and carrier base bottom correspondence is provided with two pinholes, and the steel dowel inserts pinhole carrier base is fixed on the ground, covers one deck concrete mortar on the described dowel.
Also hang a protective screening on around the inwall of described carrier base by several hooks; By the effect that protective screening further plays dual fail-safe is set.
The beneficial effects of the utility model are: by bottom lower floor's lid and the decorative cover that iron plate constitutes are set, not only reduced cost of production at the inspection shaft lid, and in light weight, and crushing resistance is good, is not easy fragmentation, distortion; And the cover plate of upper layer of inspection shaft lid adopts concrete casting to form, and can prevent the generation of noise effectively.The steel member skeleton that the inspection shaft lid is built-in has satisfied the designing requirement of intensity of load on the one hand, makes that inspection shaft lid supporting capacity is strong, and resistance to compression, tension, bending resistance, excellent in cushion effect promptly have robust characteristics.Simultaneously, also hang a protective screening on around the carrier base inwall, thereby further avoided the casualties that causes because of inspection shaft losing of cover or damage.
