Description

A kind of job practices of block pavement

Technical field:

The present invention relates to the technical field of civil engineering, specifically a kind of job practices of block pavement.

Background technology:

The 50-60 age once adopted lithotome to pave pitching pavement, the comparatively tired lock of this laying process, expend a large amount of stone materials, surface evenness is poor, present highway in China, the traditional road surface of urban road is generally with pitch, cement pavement is main, asphalt paving need consume a large amount of high-energy sources, and the road surface abrasion resistance is relatively poor, so in recent years from the external cement concrete block production line equipment of having introduced, but because shortage for the system applies research of block pavement, does not have clear and definite method for designing and construction technology, application for block pavement only rests on the sidewalk of road up to now, and building block slit, construction back is bigger, and construction cost is higher, complex process.

Summary of the invention:

The object of the present invention is to provide a kind of job practices of improved block pavement, it can overcome, and construction cost in the prior art is higher, the some shortcomings of complex process.

To achieve these goals, technical scheme of the present invention is: a kind of job practices of block pavement is characterized in that: the job practices of described block pavement may further comprise the steps, the examination of a, location, demarcation elevation and basic unit; B, making road kerb; C, setting pavior brick reference point and reference line; D, the placing sand layer paves; E, laying building block surface layer; F, butt joint are adjusted, and seam sand is irritated in the pressure back tentatively shaking; G, shake pressure, seam irritated sand till seam is filled repeatedly.

The coagulating cement earth building blocks that the present invention uses during use is produced by batch in factory, need not consume the high-energy source of pitch and so on, cost is lower, simple and convenient when paving construction, open to traffic immediately after construction finishes, maintenance is also less for the influence of communications and transportation, the road surface of adopting this construction technology to pave has the advantages that weight bearing power is big, overall flexibility is good, can adapt to various traffic patterns, application life can be above 20 years, and block is more much bigger than other road surface types, and its residual value can reuse.

The specific embodiment:

The invention will be further described below in conjunction with drawings and Examples.

The job practices of block pavement of the present invention may further comprise the steps, the examination of a, location, demarcation elevation and basic unit, at first carry out the location on road surface and demarcate elevation, check (comprise pipe trench in the basic unit and whether structure are consistent with design, whether whether each part of inspection basic unit have the intensity of rough undesirable condition, substrate surface whether to reach the requirement of design drawing with the elevation of demarcation and transverse drainage gradient unanimity, substrate surface) for basic unit according to design drawing; B, making road kerb, at first set the reference point 1 of road kerb,, reference line 2 (see figure 1)s are set by the road kerb reference point again according to the making plane design drawing, at last according to road kerb reference line making road kerb 3, and remove outstanding position 4, its basis until the road bed (see figure 2); C, setting pavior brick reference point and reference line, at first, set the pavior brick reference point on the road kerb limit, again by the pavior brick reference point according to the making plane design drawing, two orthogonal pavior brick reference lines are set, and wherein the angle of reference line and road kerb reference line is preferably 0 degree or 45 degree; D, the placing sand layer paves, the virtual resurfacing thickness of placing sand layer should be determined by test, general desirable than the high 15-20mm of design thickness, the method of placing sand layer of paving will be according to the size of engineering quantity, adopt scraper plate method, the method for raking, the asphalt paver placing sand layers that pave such as method that pave, paving does not remake any disturbance after finishing; E, laying building block surface layer during the surfacing brick, forbid to stand in operation on the placing sand layer, can be on the road brick of firm making, and the pad lastblock is greater than 0.3m ²Plank, stand in making on the plank, making produces the slit that is not more than 20mm to the roadside, and the joint gap that can suitably adjust between the pavior brick remedies, should not use cement mortar to fill up, seam should be benchmark backguy adjustment by definite two perpendicular pavior brick reference lines; F, butt joint are adjusted, and seam sand is irritated in the pressure back tentatively shaking; G, shake pressure, seam irritated sand till seam is filled repeatedly.

In force, when two or more pavior brick reference points being set simultaneously during the surfacing brick, should be according to project scale and road surface brick size, should establish the parallel pavior brick reference line of pod of 5-10m spacing, in the pavior brick seam, the place that will fill up with pea gravel concreten should be at the pea gravel concreten when daily prescribed strength grade.After having spread pavior brick, the hand steered vibration rubber tire of application specific rolling machine is rolled 2-3 time to middle road surface by Road Edge, when rolling, vibrating roller press direction of advance should be vertical with the length direction of pavior brick, pace and walking speed are suitable, and should note not making pavior brick to be subjected to undue disturbance, carry out seam then and irritate sand, when irritating sand, seam evenly spreads very thin one deck seam sand at road surfaces earlier, with instruments such as broom or scrubbing brushes the sand on the road surface is swept in the seam again, shaking to press with hand steered vibration rubber tire rolling machine then makes sand pour into seam, and seam is irritated sand and pressed and will carry out repeatedly with shaking, up to seam fill tamp till.

Pavement construction for privileged sites, (1) construction around the facility of road surface: unnecessary outstanding position should be removed around manhole, the sink hole etc., and be trimmed to the pre-face absolute altitude of basic unit with base material, pavior brick around the manhole etc. bans use of the cut-out piece, do not have the making part, and use pea gravel concreten to fill up.(2) construction of the edge on no road kerb road surface: the occasion of road kerb is not used on sidewalk, square etc., with concrete backstop method or pavior brick mortar bonding method face brick regularly.(3) transition of the road surface discrepancy in elevation: the road surface discrepancy in elevation changes larger part, sub-surface and placing sand layer should be made continuous curve-like, should not construct into polyline shaped, and its joint gap should be within 2-6mm.(4) construction on crooked road surface: crooked road surface can adopt adjustment road surface brickwork joint width to construct, and its joint gap will reach, the joint gap 〉=2mm of all pavior bricks in the joint gap≤6mm of bend periphery pavior brick, bend.(5) paving method of commentaries on classics corner pavior brick has two kinds, in-line making and herringbone making (see figure 3), and the corner pavior brick can cut off piece and pea gravel concreten making with the special-purpose pavior brick in end.(6) cutting of pavior brick: on the border on road surface or intersection can not use the end special brick time, can pavior brick cut off the back and use, the cut-out available hydraulic brick cutter or the diamond custting machine of pavior brick cut, and the minimum dimension of cutting off piece should be greater than 20mm.(7) the construction at fierce position of vibration: when the fierce position surfacing brick of vibration, the placing sand layer should use 1; 3 dry cement mortars substitute.(8) there is the basic unit upper berth of the waterproof requirement face brick of building the road to do waterproofing work and design drainage system.(9) construction of attack sites is arranged: when attack sites surfacing brick is arranged, should use 1; 3 dry cement mortar is filled seam and is tamped, and water pours in the seam again, and the dry mixing cement mortar is soaked.
