Description
Technical field
The utility model relates to a kind of anti-theft jumping-proof natural inhibiting manhole cover device.
Background technology
Press, in modern construction project, various pipelines and Facilities Construction all give undergroundization, in order to protection road safety of person vehicle and reduce the life that it disturbs people, and increase the look of the city aesthetic feeling.But the use of any subterranean pipe line and facility has the demand of maintenance or enlarging installing unavoidably, so must in position bury well lid and cage underground, and with the carrying out of convenient aforementioned work.Yet, because the texture material of well lid and cage is good, durable in use, dark rich economic worth, but because of monitoring constantly, so become one of favorite prey of stealer.
All be provided with hole or related facility that the breakdown well lid is used on the present well lid, the breakdown origin of force is arranged when making things convenient for the breakdown well lid, cause existing well lid and cage to there is no suitable theft preventing method, be at most the weight that can only increase well lid and cage itself, and well lid and manhole cover base often are embedded on the road basis, as well lid suddenly by the deathwatch, traffic bound is crossed well lid, and well lid meeting escape causes car crash.According to media report, existing well lid true case stolen, that make the people fall into the interior death of wellhole takes place, except punishing severely the personnel of committing a crime, the most basic road is still the anti-theft technique of strengthening well lid and manhole cover base, make stealer when the breakdown well lid, have no the origin of force of breakdown well lid, and make it lose the wish of stealing well lid, stealer can't be finished steal action.
Existing well lid is arranged on the carriageway more, because the vehicle dealing is frequent, causes well lid to jump out of the well head of manhole cover base, has a strong impact on road safety.The back finds that its principal element is as follows after deliberation:
One, well lid both had been arranged on the carriageway, through the wheel spreading, with the passing of time wear and tear and aging cracking, and after more renewing well lid, be that same group model is made moulding because of newly well lid and old manhole cover base are non-, cause the horizontal clearance of well lid and manhole cover base bigger, vertically be uneven.
Two, the manufacturing of well lid finished product all uses sand mo(u)ld perfusion to form, and because of the granular size of sand can't be consistent, causes well lid and the manhole cover base exposure level face can't be smooth, and the vertical plane space is too big.
Three, in the sand mo(u)ld filling process, form removal is dealt with improperly, makes the well lid distortion through process of expansion and contraction.
Four, according to checking and accepting regulation, the only sampling inspection of well lid finished product, so that be difficult to all check and accept its whether compliant size.
Five, construction or attendant open after the well lid, and finger stone, the silt particle that will not fall to stay when restoring on the manhole cover base apical margin be removed clean.
Six, well lid places on the carriageway, is positioned at the route of the normal process of wheel just as its position, and on-the-spot roadway often can be found two wheel traces, normal for a long time after, well lid is under the wheel vestige, well lid and manhole cover base are worn.Through construction or after the attendant opens well lid, be difficult to put back to the origin-location when restoring, cause the bonding surface injustice between well lid and manhole cover base, and make garage its when going up generation beat or escape.
Relevant above-mentioned deletion analysis, there is too many case to follow in fact, wherein as the traffic accident together that January 23, emerging bridge took place in the Taibei city, Taiwan Province, P.R.china in 1989, this cycling start seed of trouble is according to police investigation, to be a vehicle spreading be covered in the unexpected escape of cable culvert pipe well lid on the bridge floor in telecommunication bureau to its accident reason, cause follow its afterwards a passenger traffic bus of process bang into the well head of manhole cover base, and being upspring, flies away from whole vehicle body, and be pressed onto on the car of head-on sailing, cause four passenger's car crashes then and there on the car.Same case, the BeiJing, China caused three cyclists car crash accident then and there to take place in 2004.
According to above-mentioned traffic accident incident, behind utility model people field research, learn that it causes trouble process as shown in Figures 1 to 4, describe in detail now as the back:
Highway bridge design specifications regulation according to U.S.'s continent highway and transportation official association (AASHTO) traffic technique standard: the wheelbase Dd of standard open freight car is 4.25m, if road speed is 60km/hr, well lid RF is 0.676m, then works as the time starting point to be: ∑ T dR 〉=0
dR≥0
Front-wheel through well lid rear end R to time of front end F is:
T
RF ＝ RF/v＝0.676m/(60×1000m/hr)×60×60＝0.04056sec
Trailing wheel to the well lid rear end R time is:
T
DR ＝( Dd- RF)/M＝(4.25m-0.676m)/(60×1000m/hr)×60×60＝0.21444sec
Via above-mentioned formula, as shown in Figure 1, before vehicle no show well lid, well lid is as excellent as before, but well lid and manhole cover base exposure level face excesssive gap, vertical plane partly is uneven.Continue as shown in Figure 2, during the well lid of vehicle front-wheel contact then rear end R point, its time T
DRBe starting point,, be uneven between well lid and manhole cover base again that cause the perk of well lid front end F point, it highly is H1 because of exposure level face excesssive gap.Continue as shown in Figure 3, then the vehicle front-wheel is through T
RFWhen=0.0405sec arrives well lid front end F, because of well lid front end F has apart from H1 with cage, add for the first time the moment collision effect, make the R perk of well lid rear end, it highly be H2 than front end is height (H2＞H1).When the vehicle front-wheel just will leave the well lid front end, when being added in the front end of well lid because of vehicle gravity, the existing H1 distance that falls, add this for the second time moment collision effect, cause the well lid rear end to have upwards higher to fall apart from H2, promptly the vehicle front-wheel leaves the well lid front end, and well lid promptly becomes the seesaw action.Continue as shown in Figure 4, at last at T
DRDuring=0.214sec, when vehicle rear wheel collides well lid rear end R, well lid is hit from original position, cause the car crash major traffic accidents, jeopardize public popular safety.
Other consults Fig. 5 to shown in Figure 9, because vehicle imposes on the drag force or the compressive force effect of well lid, makes well lid produce anti-clockwise power and jumps out of the well lid pedestal, also can cause the harm of traffic accident, its process as described later:
At first, as shown in Figure 5, owing to have the space between well lid and manhole cover base, when the loaded vehicle front-wheel was pressed onto an end of well lid, the other end can perk.Continue as shown in Figure 6, then front-wheel continues to advance and since wheel impose on well lid execute drag force and compressive force, make well lid produce the power of counter rotation, the peak that takeoff this moment is also rotated by counter-clockwise direction.Continue as shown in Figure 7, current wheel load cross the well lid distal edge along the time, the peak that takeoffs moves to the right back, at this moment, perk end height has promptly exceeded road ground.Continue as shown in Figure 8, front-wheel through after, well lid be subjected to effect of inertia still can continue the rotation raise up.Continue as shown in Figure 9, according to trailing wheel to the well lid rear end R time be T
DR=0.214sec, the vehicle rear wheel of obviously in this very brief time, being passed through, the back acies of will inevitably overtaking collision kicking up to well lid because the enormous impact power of loaded vehicle, makes well lid after being impacted rotate to the right front and flies out, and influences road safety.This shows that above-mentioned known well lid still has many disappearances with being used in combination of manhole cover base, real non-one kindhearted design, and demand urgently being improved.
Again, in known relevant well lid and manhole cover base technology, have quite a lotly, be its typical case as No. the 481704th, TaiWan, China patent announcement, bulletin No. 427374 and several M240035 number of certificate number, M244316 number etc. and represent case in order to case before the patent that prevents the stolen and design of well lid or manhole cover base; Case before the patents that design in order to prevent well lid escape manhole cover base quite a lot is also arranged in addition, as No. the 211835th, TaiWan, China patent announcement, No. the 160395th, bulletin, No. the 195309th, bulletin and announce No. 491310, Chinese patent 20042006158.1 etc. and be its typical case and represent case.So, the well lid of these known cases and manhole cover base or disappearance on the structure design is arranged, and significant disadvantages is that these known cases can't reach the anti-escape of well lid and manhole cover base and antitheft dual-use function simultaneously, and the necessity that is improved is in the lump really arranged.
