Description
Technical field
The utility model relate to a kind of covered protection municipal sewage manhole, rainwater inspection well, power check well, rainwater receive well and other similar type well heads used be connected to holistic one group of hardware, just usually said inspection shaft lid.
Background technology
Mainly there are several like this problems in the casting iron well lid that uses on the urban road at present:
1, easily stolen, it is stolen to be mainly old well lid plate;
2, old well seat concrete basis damage causes old manhole lid device to sink or is loosening;
3, old well lid plate distortion, old well lid plate cooperates not tight with old well seat, and old well seat concrete basis is damaged, and causes strong impact noise then;
4, there are the steel interface that soften in old manhole lid device periphery asphalt concrete thin thickness, old well seat basis and asphalt concrete on every side, ftracture or loose so the peripheral asphalt concrete of old manhole lid device is easy;
5, " well lid plate axis of rotation bolt 4 " as shown in Figure 1 is very little apart from the discrepancy in elevation on road surface, and asphalt concrete herein is easily by the bolt disturbance, and thief can be abolished the road surface easily herein and backs out nut and steal old well lid plate;
6, in the work progress enclosing measure must be set, fall the car accident, when especially current condition is better after the roadbase making is finished otherwise fall the people easily;
7, the curing time that paves and must stay at least one week for the reinforced cementitious concrete of old well seat before the asphalt concrete upper layer, old manhole lid device installation has had a strong impact on the duration, and municipal engineering are exactly very sensitive to the duration;
8, after old well seat reinforced Concrete was built, old well lid plate hight journey can not adjust again, can only adjust pitch upper layer paving thickness and gather old well lid plate hight journey, caused crib easily and the road surface discrepancy in elevation exceeds regulating scope and surface evenness is poor.
In order to address the above problem some patent designs have been arranged.
The scheme that the antitheft problem of old manhole lid device solves is very many, and what have adds movable pin, fixing old well lid plate opening end, and pin is designed to and must opens by special tool, is 03121738.9 patent as number of patent application.What have passes through moving of lock driving pin, and passing through of having increases chain fixes old well lid plate and old well seat, is 20071005082.9 patent as the patent No. such as number of patent application.The utility model has comprehensively used chain to add lockset and the dead method of all connecting portion welderings has been reached antitheft purpose, and antitheft is not emphasis of the present utility model, just cooperates the auxiliary plan of other technological improvement.
The noise of old manhole lid device source mainly contains two aspects: the one, and damaged or basis, basis is connected with old well seat not firmly causes old well seat to become flexible, and car is arranged through out-of-date, and old well lid plate and old well seat or old well seat and old well seat basis certainly lead to impact sound; The 2nd, old well lid plate and old well seat bonding surface mismachining tolerance are big, old well lid plate deforms or the well seat on the foreign material of formation fulcrum are arranged, cause old well lid plate on old manhole cover base, can rock.In the technology of existing solution noise, what have is provided with rubber washer on old well seat, what have simply welds together old well lid plate and old well seat, what have uses machine tooling with old well lid plate and old well seat contact surface, reduce mismatch error, above-mentioned measure all is effective measures, and problem is that the load that old well lid plate bears is very big, and rubber washer will regularly replace; Open pretty troublesome after the welding again; Fine finishining can not prevent that later stage distortion or foreign material are deposited in the noise that forms on the contact surface.
Generally adopt plank or bamboo to comb to the security protection of inspection shaft in the road construction and cover, put some warning marks in addition, the security incident relevant with inspection shaft can not be thoroughly stopped in this measure.Stacked well lid external member can pave in basic unit and finish just installation of back, makes things convenient for road also not influence follow-up construction.Stacked well lid external member finishes promptly to build well pedestal concrete basis at base layer construction, crib, manhole cover base and well lid plate is installed is later on only used bolt and nut to fix, and not only firmly but also has not influenced the duration.
Sink and the periphery breakage at old manhole lid device, the technological improvement that has is the floor space increasing with old well seat, increase contact area with basic structure or roadbase, utilize the rigidity of old well seat itself that the road surface load is distributed in basis or the roadbase, thereby reducing the destruction of road pavement and manhole base, is 92234613.5 patent as number of patent application.The basis of the old well seat of prefabricated reinforced concrete walling crib conduct that has is to improve the drawback that the manhole base quality easily goes wrong.These measures have remedied the defective in the construction to a certain extent, but having ignored old manhole lid device mounting process complexity and concrete curing time insufficient is the underlying causes that causes well lid sinking and peripheral asphalt concrete breakage, and be not that unit in charge of construction has a mind to for it, exactly most unit in charge of construction does not want maintenance manhole lid device frequent in quality guarantee period.
At present the conventional steps of mounting shaft lid arrangement is, 1, after cement stabilized macadam base (or other type basic unit) operation finishes, and the anti-basic unit of excavating builds old well seat reinforced concrete base by design, and the reinforcing bar that links to each other with follow-up steel bar concrete of reservation; 2, pave flexible pavement bottom, middle level, the counter again well periphery bottom middle level asphalt concrete that excavates uses the fixing old well seat of expansion bolt, and old manhole cover base periphery steel bar concrete is built surface layer crest level to the asphalt concrete; 3, the asphalt concrete upper layer that paves.
Steel bar concrete and basic unit's maintenance synchronously (at least seven days) in the 1st step, intensity generally is guaranteed.Manhole lid device is used for municipal engineering mostly, and municipal engineering often the duration tighter, more to the end the time tight more, the concrete curing phase in such the 2nd step usually is difficult to guarantee, this step will produce three problems, the one, concrete strength hangs down cracked easily; The 2nd, the asphalt concrete of manhole lid device periphery is too thin, has only the thickness of a upper layer, is generally 4cm, and the thin pitch on the end face of concrete basis is also cracked or come off because vibrations are passed easily; The 3rd, the inhomogeneous pitch cracking that causes of the easy sedimentation in concrete edge.Owing to before old well seat is not installed, after bottom surface layer and middle surface layer asphalt concrete roll through road roller, all can subside in all several meters scopes of well, the most directly influence the planeness of upper layer pitch in addition to the well center position.
The engineering that also has is only built the reinforced concrete base elevation to roadbase and is pushed up, after middle bottom surface layer asphalt concrete paves and finishes, the bottom asphalt concrete is to the steel bar concrete end face in the anti-excavation, use the fixing old well seat of expansion bolt, if the elevation incorrect shimming of also wanting in concrete basis is regulated elevation, all asphalt concretes of the well that manually paves then surface layer in the asphalt concrete to middle surface layer elevation of top surface owing to old well lid plate hight is installed, inconvenient road roller rolls, and causes well inhomogeneous, the out-of-flatness of bottom asphalt concrete, leakiness in week.The manhole cover base that expansion bolt is fixed is also unstable.The construction quality of this method is not as good as top a kind of.
The utility model can be simplified well lid and installs, make things convenient for the asphalt concrete surface construction, has eliminated pave construction and build influence between manhole lid device basis and the manhole lid device installation procedure of pitch.
Old manhole lid device can not be adjusted height after bituminous pavement paving finishes, adjust if desired, and the basis also will be built again.The patent that has has been considered this adjustment, it as number of patent application 02800279.2 patent, this patent is dialled or pressurizing tool is mentioned crib or depressed and increase or reduce the purpose that height adjusting block reaches Height Adjustment simultaneously by custom-designed drawing, this patent design is very novel, but independent form and type of attachment to crib and well lid are not described in detail, this on the other hand afterwards being adjusted in the actual conditions is infrequent, because when really needing to adjust elevation, often old well seat basis has also been damaged, and necessity of Height Adjustment has not just had yet.Design in this patent draw the tool of exchanging work also can do change slightly after be applied in the well lid external member of the present utility model.The utility model possesses the function of adjusting height equally, and mode is simpler, and all can adjust in the thing in advance afterwards.

10. after road uses the several years, if pave again after overlaying one deck asphalt concrete or surface layer milling, only need do installation again crib and manhole cover base gets final product, do not need to water again underpin.
Example shown in Figure 25 is an exemplary embodiments of the square manhole of the utility model.The deck of road is designed to " grain formula asphalt concrete+4cm particulate formula asphalt concrete among the steady basic unit of 40cm water+8cm coarse grain formula asphalt concrete+6cm " in this example.Square stacked well lid external member consists of 6cm well pedestal+6cm crib+6cm crib+4cm crib+2cm manhole cover base (4cm well lid plate be embedded in manhole cover base in) among Figure 25, the gross thickness of manhole cover base is 6cm, its middle and lower part 4cm sinks in the crib of bottom, and manhole cover base is 2cm with the thickness that contacts of asphalt concrete.The apical side height of well pedestal is identical with the steady basic unit of water apical side height, and the well pedestal is cast in the steel bar concrete of about 3mX3m area 20cm thickness, and as shown in figure 25, the reinforcing bar binding hole 9 of well pedestal links to each other with the skeleton reinforcing steel bar in the steel bar concrete.
The specific implementation process of present embodiment is such:
1. after the water that paved is steady, counter to dig 20cm dark with 3mX3m scope around the well head, put into the good cage of reinforcement of colligation, the well pedestal is placed on the skeleton, " reinforcing bar binding hole 9 " shown in Figure 25 position is buckled on the cage of reinforcement and colligation or welding, in addition with " muscle 3 is implanted on square well concrete basis " shown in Figure 38 together with " antirust chain 2 " colligation or be welded on the cage of reinforcement.Well pedestal elevation can have error, and stacked well lid external member can be regulated elevation by the crib that uses different-thickness.
2. joints cement concrete.Concrete end face and road water steady basic unit end face and well base top surface should be in the same plane substantially.Concrete and water can be installed in 6cm crib+manhole cover base+well lid plate on the well pedestal between steady curing time, and as shown in figure 38 " lockset 1 " is locked on the well lid plate shown in Figure 27 " lock penetrates hole 1 ".The maintenance of the maintenance of concrete and the steady basic unit of water is synchronous basically, and the two will possess the condition of the asphalt concrete that paves synchronously.
3. the 8cm coarse grain formula that paves asphalt concrete, this moment, asphalt concrete design end face and well lid end face were in same plane just, and very convenient road roller rolls, simultaneously also without any need for isolating and protecting.Also removed the measure of using steel plate to cover when paving from.Need establish a special messenger roots out asphalt concrete unnecessary on the well lid.
4. in time open lockset after asphalt concrete rolls and finishes, back out connecting bolt and take off manhole cover base (containing the well lid plate), the thick crib of one deck 6cm is installed again, install manhole cover base (containing the well lid plate) then, lock the well lid plate again.Different with the round manhole cover external member is, what square well lid external member coupled together manhole cover base, crib, well pedestal is as shown in figure 26 4 stay bolts, and not resembling as shown in figure 22, the round manhole cover external member connects with the lag bolt layering.
5. the grain formula asphalt concrete among the 6cm that paves, asphalt concrete end face still and the well lid plate top surface be in same plane.Road roller still rolls very easily, still without any need for the isolating and protecting measure, and the measure that does not also need steel plate to cover when paving.
6. open lockset, take off manhole cover base (containing the well lid plate), measure the pad of precise thickness to determine the crib of what thickness should be installed or use what thickness of pitch upper layer this moment.Supposing only needs the thick crib of one deck 4cm is installed, and installs manhole cover base (containing the well lid plate), locks the well lid plate.
7. the 4cm particulate formula that paves asphalt concrete, the asphalt concrete end face still is and the well lid plate top surface is in same plane.Road roller still rolls very easily, still protects without any need for traffic.
8. before not rolling or after the first pressing as find that well lid plate hight journey and road surface elevation differ bigger, can take away 4cm crib and manhole cover base (containing the well lid plate), change the 4cm crib into thicker or thinner crib, deviation hour can use pad to regulate.If the thin crib of one deck of also can directly on the 4cm crib, installing again on the low side.This situation is still very common in municipal engineering, especially builder's road with one voice or inspection shaft quantity concentrate the place time, this is one of innovation of stacked well lid external member.
9. the electric welding welding is adopted at all bolt and nut coupling parts, middle part, well limit, locked the well lid plate.
In specific implementation process, should also be noted that following thing top:
1. though the utility model can be regulated the well lid elevation, having measured accurately when but the well pedestal is installed, elevation can save the trouble of changing the different-thickness crib or using pad, and too much use pad can cause the instability of connecting portion, need add weldering in addition.
2. pad should place between crib and the crib, had better not place between manhole cover base and the crib, in order to avoid influence the integral rigidity on well lid external member top.
3. after the installation of well lid external member, tackle all bolt and nut welding, strengthen anti-theft effect.
4. well pedestal and the reinforcing bar colligation of being sure to, preferably welding.
5. the reinforced concrete foundation periphery should exceed beyond 1 meter of the well susceptor edges, and concrete thickness should not be less than 20cm, should double-deck arrangement of reinforcement, and main muscle diameter should be greater than 12mm, and spacing is not more than 15cm.
6. pave again after the milling, or direct overlay does not need to do again manhole base on original road surface.
7. square well lid external member adopts through hole to connect, and same bolt all used in each layer installation, and the round manhole cover external member is used independent bolt and nut for every layer.
