Description
Technical field
The invention belongs to road construction fields, and in particular to rise reinforced construction method after a kind of asphalt concrete pavement inspection shaft.
Technical background
In Reconstruction of City Road construction, the Normal practice of lifting transformation inspection shaft is the concrete base first poured below well seat
Seat, then the asphalt concrete topping after installation well seat and well lid.But found in practice of construction, first lifting transformation checks
Progress asphalt concrete pavement, which paves, after well has the following problems：1) certain height difference can be formed between well lid and former road surface, no
Certain obstacle can be only caused to machine spreading operation, and after whole picture road surface brush is black, well lid periphery is combined with asphalt surface course
Easily there is faulting of slab ends in place, and inspection shaft will appear the phenomenon that rough and uneven in surface in road surface, be commonly called as " navel ", has both influenced the comfortable of driving
Property, and influence the impression quality of dark-coloured pavement；2) using black top road surface after first gug lid, can because well lid periphery asphalt surface course compared with
It is thin, the phenomenon that causing well lid periphery Damages of Asphalt Road Surface cracking, pavement quality and inspection shaft service life are influenced, after also increasing
Phase road maintenance cost；3) asphalt face layer after first lifting transformation inspection shaft, can also be in asphalt paving roller compaction process to well
Lid and pedestal concrete damage, and form hidden danger of quality.
Invention content
The object of the present invention is to provide reinforced construction method is risen after a kind of asphalt concrete pavement inspection shaft, this method solve right
The problem of original road surface structare layer is disturbed, certain height can be formed at reinforcing between well lid and former road surface by solving to rise after inspection shaft
The problem of poor, it is consistent with dark-coloured pavement color coordination to rise seat surface after inspection shaft.
The technical solution adopted in the present invention is：
Reinforced construction method is risen after a kind of asphalt concrete pavement inspection shaft, including step：
Before S1, asphalt concrete pavement carry out asphalt paving, inspection shaft is counted and is marked；
After S2, asphalt concrete pavement asphalt paving, the point centered on well lid center, using well lid diameter length as regular hexagon
Inscribed circle radius makees regular hexagon setting-out；
S3, the sideline for first cutting regular hexagon, then by the pitch in the range of regular hexagon and concrete chisel removal to certain
Depth；
S4, will cut after hole bottom and crater wall clean out, in pit slot after installation check well rise pedestal framework of steel reinforcement, inspection
It looks into after well to rise and is fixed with several adjusting bolts on pedestal framework of steel reinforcement, leveling steel plate is installed in adjusting bolt；
S5, pedestal template is risen after installation check well on the inside of inspection shaft, well seat is placed on leveling steel plate, passes through adjusting
Bolt and leveling leveling steel plate well seat simultaneously reach absolute altitude；
S6, pedestal is risen after pouring inspection shaft, before concrete initial set, one layer of black cement, coagulation is dispensed in concrete surface
Pedestal is risen after soil solidification, after inspection shaft and is fixed as an entirety with well seat, pedestal template is risen after removing inspection shaft and well lid is installed.
Further, in S3, depth is cut as 30cm below grade elevation.
Further, in S3, when cutting, vertical road surface carries out downwards, when encountering original concrete plate, first by coagulation
Native plate is cut again after being cut along sideline.
Further, in S6, the concrete poured is the steel fiber reinforced concrete mixed with micro-expanding agent.
Further, in S6, black cement is iron oxide black cement.
Further, in S6, during concrete setting, in inspection shaft periphery installation activity enclosing.
Further, in S6, during concrete setting, with covered rearing with plastic film curing concrete to design strength.
Further, the frame that pedestal framework of steel reinforcement is circular ring shape, the inner ring including being located at upper and lower both sides are risen after inspection shaft
Reinforcing bar, outer shroud reinforcing bar and intermediate ring reinforcing bar and connection reinforcing bar.
The beneficial effects of the invention are as follows：
By well lid periphery certain distance range internal cutting, pitch and concrete are then cut, is finally poured, using first cutting
The mode poured again solves the problems, such as disturbed to original road surface structare layer, it is possible to reduce later period maintenance cost of upkeep.
Using adjusting bolt and leveling leveling steel plate well seat and absolute altitude is reached, well at reinforcing is risen after solving inspection shaft
The problem of forming certain height difference between lid and former road surface, can effectively improve bituminous paving driving comfort level, and reduce well
Lid is by the vehicle-mounted rear impact noise generated.
Before concrete initial set, one layer of black cement is dispensed in concrete surface, seat surface and black road are risen after making inspection shaft
Face color is harmonious.
It cuts range to determine with well lid positions and dimensions, the inspection shaft of arbitrary dimension is all suitable for, setting-out shape is positive six
Side shape, conveniently cuts operation and reduction as far as possible cuts space.
