Description
Technical field
The present invention relates to Municipal Road Engineering technical field of construction, more particularly to a kind of town road heavy well cover walling crib
Ruggedized construction and its construction method.
Background technology
Major part urban road in China's is steady using lime stabilized soil, lime-fly-ash stabilization soil, lime fly ash at present
Determine rubble and cement stabilized macadam to belong to semi-rigid plate body as road deck structure as base layer structure, bituminous concrete and hold
Carry structure design.Based on inspection shaft uses armored concrete in road, concrete segment or brick setting are well bore, are used in well week
2:8 dirt or graded sand and stone backfill, armored concrete is prefabricated or preliminary shaft is built in building block (brick) by laying bricks or stones, spheroidal graphite cast-iron walling crib (lid) with 30~
The C30 concrete parcel that 50cm is wide, 25cm is thick, reserved 4cm thickness perform asphalt concrete pavement structure, belong to rigid structure and set
Meter.Overlapped between road and inspection shaft both structure types using bituminous concrete, once multibody system sedimentation is uneven, dynamic
Bituminous concrete lap-joint is easily sheared destruction under load action, or well week backfill (surface layer) roll it is unreal, pour it is not whole,
The reasons such as mortar strength is inadequate, well lid installation is undesirable cause superficial layer cracking herein.If repaired not in time, rainwater enters
Enter roadbase, damage face will progressively expand.
The content of the invention
It is an object of the invention to provide a kind of town road heavy well cover walling crib ruggedized construction, effectively solve it is current I
The inspection shafts such as rainwater, sewage, reclaimed water, upper water, combustion gas and telecommunications in the range of state's urban road occur well lid periphery (10~
35cm) the quality problems such as pavement cracking, breakage and well lid sinking, ensure municipal road pavement flatness so that road-ability
It is greatly improved with safety, while reduces road maintenance, maintenance costs.
To achieve the above object, the invention provides following scheme：The present invention provides a kind of town road heavy well cover well
Ruggedized construction is enclosed, including prefabricated walling crib, cystosepiment and the pit shaft set gradually from top to bottom, the bottom of the prefabricated walling crib have
The prefabricated well cycle basis seat of integrally connected, the cystosepiment are arranged between the prefabricated walling crib and the pit shaft, the prefabricated well

Optionally, it is equipped with one layer pair on the surface of the concrete and the upper basic unit of the road structure layer first poured
To GSZ, the top of the direction earthwork grille is roadway base surfaces layer.
Optionally, a screed-coat has been poured between the bottom of the prefabricated well cycle basis seat and the underlayment of road structure layer.
Optionally, the cystosepiment is low density polyethylene (LDPE) closed-cell foam plate, and the low density polyethylene (LDPE) closed-cell foam
The thickness of plate is 100mm.
Optionally, the outside of the pit shaft and be roadbed positioned at the bottom of the road structure layer, the roadbed passes through well
All backfilling materials be filled and it is counter after the completion of filling dig, the well week backfilling material is graded sand and stone backfilling material.
The town road heavy type well curb well lid carried out using above-mentioned town road heavy type well curb well lid ruggedized construction reinforces knot
The construction method of structure, Specific construction step are：
Roadway base surfaces layer and upper roadbed shared by anti-digging inspection shaft and its surrounding etc.；
The roadbed of pit shaft surrounding is complete by the backfilling material backfill of well week according to specification, then lay one layer of pitch coagulation
Soil；
The underlayment of laying road structure sheaf, and lay one layer of bituminous concrete on the surface of underlayment；
Low density polyethylene (LDPE) closed-cell foam plate is fixed on the top of pit shaft, and on the top of the underlayment and described low
The periphery of density polyethylene closed-cell foam plate pours screed-coat by ready-mixed concrete；
Laid on the top of the screed-coat and low density polyethylene (LDPE) closed-cell foam plate prefabricated with prefabricated well cycle basis seat
