Abstract
The utility model provides a multifunctional multi-component manhole cover and shaft. The multifunctional multi-component manhole cover and shaft comprises a manhole cover and a manhole shaft, wherein the manhole cover and the manhole shaft are used in cooperation, the manhole cover is formed by an annular or spiral framework in an adhesive coating and rolling mode, the manhole shaft is formed by at least two telescopic cylinders in a sleeved mode, the telescopic cylinders are provided with internal threads and external threads, a lock catch mechanism is arranged at the position of connection between the manhole cover and the manhole shaft, and a falling preventing mechanism is arranged in the manhole shaft. The multifunctional multi-component manhole cover and shaft has the advantages that due to the fact that the telescopic mode is adopted, the multifunctional multi-component manhole cover and shaft can be applicable to manholes with different depths; reinforcing ribs are arranged in the shaft wall, so that strength of the manhole shaft is greatly improved, and the service life of the manhole shaft is prolonged; due to the fact that the falling preventing mechanism is arranged in the manhole shaft, even when the multifunctional multi-component manhole cover and shaft is damaged for some reason or stolen, the accident that pedestrians fall into the manhole can be effectively avoided through the falling preventing mechanism, and personal safety of people is improved; due to the fact that the lock catch mechanism is adopted, the manhole cover is prevented from being lost, and safety of public property is improved; due to the fact that the manhole cover and the manhole shaft are respectively made of novel materials, the weight is light, strength is high, acid resistance and alkali resistance are high, and the service life is long.
Description
Technical field
The utility model relates to manhole field, refers in particular to a kind of multi-functional polynary composite cover for manhole and pit shaft.
Background technology
Manhole is to be used in that buried plastics pipe road external diameter is not more than 800mm in the scopes such as residential community, one residential, public building district, plant area, the depth of burying is not more than 6m, generally be located at drainage pipe intersection, turning, caliber or gradient change place, drop place etc., for the ease of making regular check on, the plastics integrated injection molding of the inspection use of clean and dredging or down-hole operation form or brick become well shape structure.Existing well lid is to adopt concrete to cast or cast iron manufacture mostly, the weight of concrete manhole cover is at 70 to 90 kilograms, the difficulty of uncapping, close while lid and accidentally will break into pieces or hurt sb.'s feelings, although casting iron well lid is not heavy, but casting iron well lid can send the very large sound in the time that vehicle rolls, produce noise, the sound and the noise that particularly produce night more make overlooking resident deeply influenced, and the poor toughness of cast iron casting well lid, get rusty easily, and often stolen, will cause not in time car accident and personal injury once augment after stolen.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, intensity is high, antitheft, anti-fall and applicable to the flexible well lid of the manhole of the various degree of depth and pit shaft.
For achieving the above object, technical scheme provided by the utility model is: a kind of multi-functional polynary composite cover for manhole and pit shaft, it includes the well lid and the pit shaft that cooperatively interact, well lid is molded by covering rubber-surfaced roll by annular or spiral skeleton, and the retracting cylinder fit that pit shaft has internal and external threads by least two joints forms; The junction of well lid and pit shaft is provided with latching device, is provided with safety dropping prevent mechanism in pit shaft.
Described well lid upper surface is provided with reflective tape and drain hole.
On the skeleton of described well lid, run through or be coated with reinforcing rib, skeleton gap and surrounding are all pressed by covering rubber roll.
In described pit shaft barrel, be provided with strip bamboo reinforcement or steel band.
In described pit shaft barrel, be provided with spiral bamboo reinforcement or steel band.
Described latching device is made up of one group of thread mechanism, and wherein, external screw thread is around twisting on well lid sidewall, and internal thread is positioned at pit shaft tube port position.
Described safety dropping prevent mechanism is fixed on flexible inner core bottom, is made up of anti-drop net or anti-fall fence.
The utility model has the advantage of:
The first, adopt stretch mode, well is looked in the inspection that goes for the various degree of depth, has increased greatly the scope of application of pit shaft.
The second, in barrel, establish reinforcing rib, greatly strengthened pit shaft intensity, extend the application life of pit shaft.
Three, in pit shaft, establish safety dropping prevent mechanism, even damage or stolen for some reason, safety dropping prevent mechanism also can effectively prevent pedestrian's falling accident, increases people's personal safety.
Four, adopt latching device, prevent well lid loss, increase public property safety.
Five, well lid and pit shaft all adopt new material to make, lightweight, intensity is high, acidproof, alkaline-resisting, long service life.
