Abstract
The invention discloses an inspection well protective cover, and belongs to the technical field of inspection well cover frames. The inspection well protective cover is for current numerous sewer inspection wells which exit in cities. The designed structures of the current sewer inspection wells have no safety protective devices, so that safety accidents that pedestrians fall into inspection wells when inspection well covers are lost unexpectedly are easy to happen. The inspection well protective cover is designed to improve an existing inspection well and enables the inspection well to possess safeguard functions. The inspection well protective cover is characterized in that the inspection well protective cover is of a conical disc structure, symmetrical buttonholes (1) are formed in the round disc opening edge (4), strengthening ribs (3) are evenly distributed in the cone face, the round disc opening edge (4) is of a Z-shaped double-bender structure, mesh penetrating holes (2) are formed in the bottom of the inspection well protective cover, and the inspection well protective cover is made of reclaimed waste plastic and is arrange under an inspection well cover. The inspection well protective cover is simple in design, convenient to install, low in production cost, and is beneficial for the safety setting improvements for the current numerous inspection wells which exist in the cities.
Description
Technical field
The invention belongs to the technical field of Seat for manhole cover, especially a kind of inspection shaft protective cover.
Background technology
The inspection shaft of urban road comprises that " rain, sewage, communication, tap water, natural gas, electric power, chemical industry etc. pipeline inspection shaft is the hole that facilitate engineering staff come in and go out of shielding for safeguarding that underground utilities are reserved at present.Use in the city and to manage the department of pipeline inspection shaft numerous, the quantity of pipeline inspection shaft is very big.Total all kinds of inspection shafts are 1,230,000 in the Wuhan City, belong to 18 accountability unit such as water utilities, electric power, communication, combustion gas.On densely populated avenue, inspection shaft mismanagement and the security incident that causes occur at any time, make up very necessity of managerial deficiency with safe design and the safeguard procedures of inspection shaft.But the design specifications of the urban road pipeline inspection shaft in the Shanghai City that industrial technology is leading does not now provide necessary safety to arrange yet.As above " the separate type Seat for manhole cover " of Haiti side's design standard on the closing in member of inspection shaft pit shaft, overlapping the pedestal basis, is Cover of inspection well and cast iron seat with the pavement of road design elevation on pedestal, central without any the safety precaution design.When the unexpected disappearance of Cover of inspection well, inspection shaft is as the tiger’s jaw that eats the people, and walking reaches by bike because do not note encountering without the injured people of the inspection shaft of well lid just more.On-hand quantity very large inspection shaft in city is carried out transformation with safe precaution measure, guarantee that pedestrains safety is necessary.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, exploitation has a kind of inspection shaft protective cover of safety precaution purposes.
Technical solution of the present invention is as follows:
1, a kind of inspection shaft protective cover, is characterized in that, as shown in the figure, the inspection shaft protective cover is designed to conical disk-like structure, when producing this part in enormous quantities, easily stacks and transport.
2, the buttonhole 1 that has symmetrical installation protective cover to use on the disk peristoma 4 of inspection shaft protective cover, the center that is shaped as of buttonhole 1 is circular perforation, what the perforation both sides were connected is the strip slotted eye less than Circularhole diameter, when the inspection shaft protective cover is installed, after bolt head passes circular hole, rotate protective cover, bolt head just is stuck on slotted eye, fix the inspection shaft protective cover, the installation and removal of inspection shaft protective cover are more convenient like this.
3, be designed with equally distributed reinforcing rib 3 on the taper seat of inspection shaft protective cover, under same wall thickness, can improve the protective cover intensity of conical plate-like structure, improve the ability of resistance to deformation and destruction.
4, the disk peristoma 4 of inspection shaft protective cover is designed to Z-shaped two-fold structure, can be buckled in during installation on inspection well seat, and the two-fold structure also can improve the intensity of protective cover.
5, there is the perforation 2 of mesh shape the bottom surface of inspection shaft protective cover, facilitates flowing of water, can drain rainwater, and the water that also prevents sewer is washed protective cover during from following rise open.
6, the inspection shaft protective cover uses the waste or used plastics manufacturing of reclaiming, and product is the environment of the suitable sewer of burn into not,
Can economize on resources and environmental protection simultaneously.
Description of drawings:
Accompanying drawing is the structure chart of inspection shaft protective cover, has on figure: the disk peristoma 4 of buttonhole 1, reticulate perforation 2, reinforcing rib 3, two-fold structure.
The specific embodiment:
Specific embodiments of the invention:
A kind of inspection shaft protective cover, it is characterized in that, as shown in the figure, the inspection shaft protective cover is conical disk-like structure, symmetrical buttonhole 1 is arranged on the disk peristoma 4 of inspection shaft protective cover, even distribution reinforcing rib 3 on taper seat, disk peristoma 4 is Z-shaped two-fold planform, netted perforation 2 is arranged in the bottom surface, and the inspection shaft protective cover uses the waste or used plastics manufacturing of reclaiming.
