Description
Technical field
The present invention relates to the construction of municipal inspection shaft, the more particularly, to a kind of well lid construction method of road surface inspection shaft and auxiliary
Erecting device.
Background technology
For many years, the inspection shaft well lid of various pipelines is installed is all the weak link of municipal road construction, and town road is examined
The construction quality looking into well well lid directly influences the flatness on road surface, road-ability, safety, aesthetics and road longevity
Life.Traditional construction technology, cover seat of manhole directly can pass to inspection shaft well head end face the pressure perpendicular coming from above, with heavy type
It is increasing that vehicle travels, and after the impact being constantly under pressure, easily causes well lid fragmentation, sinking, destroys road surface knot
Structure, decreases the service life of road.Meanwhile, traditional construction technology is that absolute altitude lateral stay with reference to curb determines well mostly
The absolute altitude of lid, this method is simple, but have ignored the head fall of road, causes actual elevation and designed elevation to have
Enter, the situation of pavement roughness easily occurs.Patent No. zl200910230438.8, patent name are road inspection well coagulation
The patent of invention of native monolithic casting construction method and construction harness is improved to traditional construction technology, using fixed support
Suspention harness adjustment well lid elevation, pours into a mould, to walling crib foundation ditch, the globality that concrete improves structure, but still suffers from following aspect
Deficiency, such as: need in an installation to suspend harness adjustment well lid elevation in midair by fixed support, the process of adjustment not only needs to spend greatly
The time of amount, and it cannot be guaranteed that the concordance of construction quality.Meanwhile, need to pour substantial amounts of concrete at the scene, construction is made
Industry time length is it is impossible to timely complete installing and follow-up maintenance of well lid, the occupancy road surface time is long, affects traffic.
Content of the invention
The first object of the present invention is to overcome cover seat of manhole installation exercise time length of the prior art it is impossible to ensure construction
A kind of shortcoming of quality conformance, there is provided the well lid construction method of road surface inspection shaft.
The second object of the present invention is to overcome cover seat of manhole installation exercise time length of the prior art it is impossible to ensure construction
A kind of shortcoming of quality conformance, there is provided the auxiliary installation device of the well lid construction of road surface inspection shaft.
The present invention realizes the well lid construction method that the first goal of the invention the technical scheme is that a kind of road surface inspection shaft,
Specifically include following steps:
A, carry out the integral prefabricated of concrete walling crib and cover seat of manhole, cover seat of manhole is arranged in concrete walling crib and is fixedly connected
Integral；
B, dig walling crib foundation ditch, walling crib foundation ditch is with diameter greater than inspection shaft external diameter and concrete well loop diameter；
C, the well head support internal mould of reducing is installed in inspection shaft well head, well head support internal mould outer rim is close to inspection shaft well
Mouth inwall, well head support internal mould one end is arranged in inspection shaft well head, the other end upwardly extends；
D, the well head support internal mould described in step c and between walling crib foundation ditch filling design consumption concrete；
E, lifting levelling device will be mixed in walling crib foundation ditch to the concrete walling crib described in step a and cover seat of manhole integral hoisting
On solidifying soil, the axis of cover seat of manhole and the dead in line of inspection shaft, cover seat of manhole is levelling with road surface positioning；
F, into walling crib foundation ditch and precast concrete walling crib filling and compacted concrete, by the overfall of well head support internal mould
Observation panel observes the occupied state of concrete, makes concrete walling crib and inspection shaft upper surface viscous and integral, and by concrete well
The space filling being formed between circle and walling crib foundation ditch is full；
After g, concrete initial set to be filled, reduce well head support internal mould diameter, take out well head support internal mould and lifting is adjusted
Leveling device；
H, lay asphalt concrete pavement between walling crib and road surface.
Also include step i, according to train-passing through conditions needs, setting on road surface is more than the cover sheet of walling crib foundation ditch diameter,
After the completion for the treatment of asphalt concrete pavement maintenance, remove cover sheet, complete the construction of road surface inspection shaft entirety well lid.
Well head support internal mould upper end described in step c differs the height of asphalt concrete pavement with road surface.
In described step e, cover seat of manhole and road surface positioning are levelling, and concrete mode is that cover seat of manhole is arranged on lifting leveling dress
Put, the datum clamp face of lifting levelling device is fitted with the upper surface of cover seat of manhole, by the datum clamp face of lifting levelling device
It is placed on levelling on road surface.
In four head end of described lifting levelling device, cushion block is installed in advance, for well lid datum level and road surface it
Between settle pre- allowance.
Described concrete is fast rigid concrete.
The present invention realizes the auxiliary that the second goal of the invention the technical scheme is that a kind of well lid construction of road surface inspection shaft
Erecting device, auxiliary installation device includes well head support internal mould and lifting levelling device, and described well head support internal mould is cylinder
Shape, cylinder side wall is provided with the opening of insertion in the axial direction, and opening both sides form the structure of juxtaposition, the intersection weight of opening
Folded place is formed at diametrically opposite under external force effect or move toward one another structure, and lifting levelling device includes leveling die and lifting
Connector, hoisting connecting piece is respectively arranged at two ends with suspension hook and suspension ring, and the lower surface of leveling die is to connect with road surface during lifting well lid
Tactile datum clamp face, leveling die is detachably coupled with hoisting connecting piece.
The invention has the beneficial effects as follows: mix with the integral prefabricated of cover seat of manhole with using rigid soon due to carrying out concrete walling crib
Solidifying soil, pours too many concrete without in walling crib foundation ditch during in-site installation, decreases the time of pouring.Only need during actual installation
The datum clamp face of lifting levelling device is placed on road surface, the hoisting structure of the present invention ensure that the upper surface of cover seat of manhole
Fit with datum clamp face, so in installation process, the upper surface of cover seat of manhole remains fair with road surface, even if eliminating
The step of adjustment well lid elevation, still can ensure that the smooth of overall road surface after installation, improves the installation dimension precision of well lid.
Well head support internal mould can strut or retract for different construction procedures, beneficial to construction and dismounting.Using standardized components and hanging
Debug leveling device and carry out do mechanization operation, improve efficiency of construction it is ensured that the concordance of construction quality, can be high-quality and efficient
Complete installation and the maintenance construction of asphalt concrete pavement well lid.Have that construction is simple, the activity duration is short, well lid installation dimension essence
The advantages of spend high.
