Description
Technical field
The present invention relates to a kind of road surfacing method, what be specifically related to is sandstone waste material sidewalk construction process.
Background technology
Sidewalk (sidewalk; Footway) refer in road by the part specializing in walk that road kerb or guardrail and other similar facilities are separated.In city, sidewalk is very general, Pang Junyou sidewalk, general street.Across meadow or trees between the sidewalk in some place and motorway.
In city also known as the street of continuous architectural complex, refer to and exceed roadway sections to building line from the road kerb marking roadway boundary line, kerb (flowing water stone), specialize in walk, forbid illegally occupying, also forbid that vehicle sails into, but it is current on pavement that walk one's bicycle walking or disabled person on pavement shake wheel-chair, should treat by pedestrian.Exit, lane or unit exit are by sidewalk truncation part, though be the area that pedestrian and vehicle pass through jointly, must be considered as is the sidewalk be truncated, and vehicle has passed through pedestrian when passing through herein, must slow down or Stop and give way, to ensure safety.
The working procedure of sidewalk surface construction mainly comprises surveying setting-out, based process, tile work and on-the-spot cleaning.Described based process: be that the table of ground soil or foreign material are removed, be then aided with manual amendment with after Mechanical Planarization compacting.Wherein, the existing process of deployment of this tile work is as follows:
(1) lime fly ash gravel compound is adopted to be laid on ground as bottom, the thick 20cm of substructure;
(2) pave bed course, bed course adopts M7.5 cement mortar, and thickness is 2cm, keeps flat gently when paving, and beats and stablizes levelling, but must not damage corner with rubber hammer;
(3) basic unit first flattens before paving by face brick, with road kerb top, both sides be as the criterion hang longitudinally with horizontal altitude traverse, first segmentation floating screed, after fill a vacancy and mat formation, check position and elevation at any time;
(4) finally face brick is laid.
Because adopting the preserving period of above-mentioned face brick to be generally no less than 7 days, the walking about and colliding of pedestrian, vehicle etc. should be forbidden during this period, and then cause construction period longer.
And after having constructed, if run into rain continuously or rainstorm weather time, rainwater cannot seepage fast, and then is stacked into face brick lower floor, causes drainage effect bad.And because long-term rain soaks, easily cause face brick lower floor depression degree everywhere different, and then cause face brick uneven, and then cause pedestrian very inconvenient when walking.
And be deposited in face brick lower floor due to rainwater, and to differ the uneven row of tile surface caused due to face brick lower floor depression degree everywhere, when easily causing walking, ponding splash is on pedestrian's leg.
Summary of the invention
The object of the invention is to solve existing People's Bank of China road surface face brick lay after ponding can not discharge fast, the problem of brick uneven impact walking quality after a period of time, provide a kind of can Quick drainage, reduce the face brick lower floor different sandstone waste material sidewalk construction process causing uneven situation to occur of depression degree everywhere.
For solving above-mentioned shortcoming, technical scheme of the present invention is as follows:
Sandstone waste material sidewalk construction process, comprises the following steps:
(1) sieve, select process: the grains of sand utilizing screening plant fineness modulus to be less than 3.7 sieve out from building debris; Metal in building debris, wooden unit and plastics are picked out;
(2) break process: put into construction waste crusher by selecting rear remaining building debris in step (1), and be ground into the finished particle being less than 10cm, and then process through step (1);
(3) after consolidation, be laid on ground with the steel bar that cross section is groove-like, and then be filled between two steel bars with the finished particle being less than 10cm; Wherein the height of steel bar is greater than 15cm, and steel bar is provided with through hole and lays one deck geotextiles in the groove of this steel bar, and the laying depth of finished particle is not less than 20cm;
(4) after finished particle has been laid, between adjacent two steel bars, the geotextiles of more than one deck is laid, and by the end winding support of geotextiles on steel bar;
(5) after geotextile laying completes, then the grains of sand sieved out in step (1) and step (2) are routed in geotextiles, then lay face brick with concrete on grains of sand top.
The present invention adopts the paving mode of the upper strata grains of sand, lower floor's finished particle, effectively improves the leak rate of ponding; The laying of geotextiles between the upper strata grains of sand and lower floor's finished particle, effectively avoids the grains of sand to flow in lower floor's finished particle along with rainwater, ensures the seepage effect of ponding.
Meanwhile, the laying of this geotextiles, not only effective in isolating between the grains of sand and finished particle and then ensureing seepage effect, and can also reinforce finished particle top layer when lower floor's finished particle has part depression, effectively reduce the effect of depression.
And the present invention adopt the grains of sand and finished particle be all adopt building debris processing after make, the environment stress that building waste brings can be alleviated, simultaneously save building waste transport and process time and cost, effect is very remarkable.
Magnetic method is adopted to be picked out from remaining building debris by ironwork in described step (1); And then the building debris after selecting is put into salt solution, by salt buoyancy of water, the wooden unit in building debris and plastics are picked out, finally by artificial method, other metal products are picked out from building debris again.
Ironwork, plastic products and the woodwork in building waste can not only be filtered out by above-mentioned screening technique substantially, and abundant fragmentation can be carried out to the material of Large stone substantially, save the broken time.
Because the space of contact surface between finished particle and ground is comparatively large, the pressure causing the position ground of the Contact of finished particle ground to bear is comparatively large, thus easily causes the region yields degree at often walking position larger.In order to solve the problem, the present invention is also equipped with the blinding that a layer thickness is 5 ~ 10cm between described ground and finished particle, and this blinding is obtained by the finished particle fragmentation in step (2), and the particle after fragmentation is less than 3cm.
When to rain continuously or when raining in torrents, rainwater infiltrates face brick lower floor, is stacked into the gap between the grains of sand and finished particle, when ground can not receive the water of infiltration completely, road pavement can impact, thus, be communicated with the aqueduct of the position, roadside being positioned at People's Bank of China road surface at finished particle place.Due to the setting of aqueduct, effectively discharge the ponding be deposited in finished particle, while the ecology not affecting this road surface place of People's Bank of China, effectively ensure that the discharge of ponding, effect is very remarkable.
Preferred as one, described grains of sand laying depth is 10cm ~ 20cm; Distance between described adjacent two steel bars is 2m ~ 4m.
The present invention compared with prior art, has the following advantages and beneficial effect:
Drainage effect of the present invention is good, avoids ponding; Effectively can reduce the sinking degree on face brick top layer simultaneously, so when can effectively avoid pedestrian to walk ponding splash to it.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment
Sandstone waste material sidewalk construction process, is characterized in that, form primarily of following steps:
