Description

The inspection well cover to combine together with road

Technical field

The inspection well cover that a kind of and road combines together, belongs to road construction and inspection well cover new technical field, is a kind of inspection shaft The new construction and new method of lid.This inspection well cover and road combine together, not only eliminate the patch phenomenon on road surface, prior To solve the problems such as hollow at road cover for manhole, increase substantially vehicle by when comfortableness and security.

Background technology

Inspection well cover on present road, not only causes have patch phenomenon on road surface, influences the appearance of the city, it is often more important that height is not It is flat, it is rugged the phenomenon that it is very universal, seriously affected vehicle by when comfortableness and security；Heavy rain, which washes away well lid, to be made It into the example of personal injury, also happens occasionally, inventor also once cycled therefore reason and fell down.Causing road surface cover for manhole, these are asked There are many reason for topic, there is quality of materials problem, construction quality problem etc..Even if the above problem solves, can also there are two Basic reason is difficult to solve：First, inspection shaft and subgrade settlement differ；Second is that since road surface is different with cover for manhole material, structure, To vehicle by when the effect that generates also differ.The invisible manhole cover of domestic some factories production, is mainly covered on well lid It is helpful to eliminating road surface patch phenomenon with the pavior brick as road surface etc., but without effect the defects of to overcoming hollow.Overseas have By the buried way under pitch of cover for manhole, when shortcoming is that well lid is opened in maintenance, to dig up pitch above, then be covered with again Pitch, it is cumbersome.

The content of the invention

The inspection well cover that a kind of and road combines together, such as Fig. 1 have walling crib 1, there is well lid 2, have fixing screws 4, there is fixed spiral shell Protection plug 5 above nail 4；There is inspection shaft 6；Strengthen ground 7；Pavement asphalt 8.Such as Fig. 2, there is 1 inner rim of walling crib to have taper cage ring 3.1, transition zone 3.10；There is fixing threaded hole 4.1 in centre, and the sole 1.1 with safe edge is arranged at bottom.Such as Fig. 3, there is 2 outer periphery of well lid to have Taper cage ring 3.2, transition zone 3.20；There is pull rod screw hole 4.2 in centre.

The inspection well cover of the present invention, there are three main features：First is fixed on walling crib and the roadbed walling crib one by one that combines together It on roadbed, can overcome originally because walling crib is fixed on inspection shaft, cause and subgrade settlement different problems；Second by ring cover face and Combine together pitch being covered with one by one on well curb well lid as road surface etc. on road surface, so not only eliminates patch phenomenon, more Can overcome the problems, such as pavement asphalt and well curb well lid because of material and structure is different generates, increase vehicle by when comfort.The Three are fitted close combine together well lid one by one and walling crib of well lid and walling crib, and are fixed with screw-driving, can effectively overcome because of well Lid loosens a series of defects generated, can more prevent heavy rain from washing away the various tragedies of well lid generation.In addition, the fixation spiral shell of the present invention Nail 4 has protection plug 5 above, and effect is the duct that screw 4 is twisted in protection.The present invention taper cage ring effect be allow well lid and Walling crib can easily be fitted close but also easily facilitate separation, while can protect well curb well lid rapid wear edge.Cage ring side On the effect of transition zone be that formation is hardly damaged and easily changeable marginal layer, and make the edge of cover for manhole and road surface, well lid The soft transitions such as the bitumen layer of the inside.Cage ring and transition zone form edge and easily change part, as long as replacing this part during damage, make Simple is become to the repair at cover for manhole.Such well lid can also be flexibly opened and closed, and ensure maintenance repair.

Description of the drawings

Fig. 1 is that walling crib, lid are fitted together, and is placed in the schematic diagram on ground subsoils, the above is walling crib, the main section view of lid Figure, here is top view.From Fig. 1 can see walling crib, well lid primary structure and installation method.Fig. 2 and Fig. 3 is well respectively The independent drawing of circle and well lid, can therefrom see some small structures that they have above.

Specific embodiment

Walling crib, Gai Shi are made, walling crib 1 and well lid 2 can be made with materials such as concrete, cage ring is made with plastic or other material 3.1 and 3.2.Walling crib 1 installs cage ring 3.1, in 3.1 periphery of cage ring of walling crib 1, can first be poured again under metal die help It is poured in transition zone 3.10；Well lid 2 installs cage ring 3.2, can be again under metal die help, in the cage ring 3.2 of well lid 2 It pours in week and is poured in same transition zone 3.20；Well lid 2 is put into walling crib 1, larger well lid pull rod screw hole is passed through with screw 4, into Fixation is tightened after entering walling crib fixing threaded hole, then protection plug 5 is loaded onto on screw 4, finally in the good pitch of well lid upper.When So, if product quality is of less demanding, transition zone 3.10 and 3.20 can not be done.If whole Transporting is had any problem, building site can be arrived Well lid is packed into walling crib again afterwards.
