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 (side walk; Foot way) refer in road the part of specializing in walk of being separated with road kerb or guardrail and other similar facilities.In city, sidewalk is very general, Pang Junyou sidewalk, general street.Between the sidewalk that some is local and motorway across meadow or trees.
In city, claim again the street of continuous architectural complex, refer to road kerb from marking roadway boundary line, kerb (flowing water stone) to building line and exceed roadway part, specialize in walk, forbid illegally occupying, also forbid that vehicle sails into, but it is current on sidewalk that walk one's bicycle on sidewalk walking or disabled person shake wheel-chair, should treat by pedestrian.Exit, lane or unit exit be sidewalk truncation part, though be the common current area of pedestrian and vehicle, must be considered as is the sidewalk being truncated, and vehicle has been passed through pedestrian while passing through herein, must slow down or Stop and give way, to guarantee safety.
The working procedure of sidewalk surface construction mainly comprises measures unwrapping wire, based process, tile work and on-the-spot cleaning.Described based process: be that table soil or the foreign material of ground are removed, then with being aided with manual amendment after machinery leveling compacting.Wherein, the existing process of deployment of this tile work is as follows:
(1) adopt lime fly ash gravel compound 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, while paving, keeps flat gently, with rubber hammer, beats stable levelling, but must not damage corner;
(3) face brick is paved Qian Xianjiang basic unit leveling, with both sides road kerb top, be as the criterion and hang longitudinally and horizontal altitude traverse, first segmentation floating screed, after fill a vacancy and mat formation, check at any time position and elevation;
(4) finally lay face brick.
Because adopting the preserving period of above-mentioned face brick to be generally no less than 7 days, should forbid during this period the walking about and collide of pedestrian, vehicle etc., and then cause construction period longer.
And after having constructed, if while running into continuously rainy or rainstorm weather, rainwater is 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 because rainwater is deposited in face brick lower floor, and the uneven row of tile surface that differs and cause due to face brick lower floor depression degree everywhere, while easily causing walking, ponding splash is to pedestrian's leg.
Summary of the invention
After the object of the invention is to solve existing People's Bank of China road surface face brick and laying ponding can not discharge fast, the problem of the uneven impact walking of brick 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 that causes 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 processing: utilize screening plant that fineness modulus is less than to 3.7 the grains of sand and 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 (2), and be ground into the finished particle that is less than 10cm, and then process through step (1);
(3) after ground compacting, the steel bar that is groove shape with cross section is laid on ground, and then is filled between two steel bars with the finished particle that is less than 10cm; Wherein the height of steel bar is greater than 15cm, and on steel bar, is provided with through hole and in the groove of this steel bar, lays one deck geotextiles, and the laying depth of finished particle is not less than 20cm;
(4), after finished particle has been laid, between adjacent two steel bars, lay geotextiles more than one deck, and the end of geotextiles is fixed on steel bar;
(5) after geotextile laying completes, then the grains of sand that sieve out in step (1) and step (2) are routed in geotextiles, then on grains of sand top, lay face brick with mixed earth.
The present invention adopts the paving mode of the upper strata grains of sand, lower floor's finished particle, effectively improves the seepage speed 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 along with rainwater flows in lower floor's finished particle, guarantees the seepage effect of ponding.
Meanwhile, the laying of this geotextiles not only effectively to isolating between the grains of sand and finished particle and then guaranteeing seepage effect, and can also be reinforced finished particle top layer when lower floor's finished particle has part depression, effectively reduces the effect of depression.
And the grains of sand that the present invention adopts and finished particle are all to make after the building debris processing adopting, and can alleviate the environment stress that building waste brings, time and the cost saving building waste transportation simultaneously and process, effect is very remarkable.
In described step (1), adopt magnetic method that ironwork is picked out from remaining building debris; And then the building debris after selecting is put into salt solution, and 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.
By above-mentioned screening technique, can not only filter out substantially ironwork, plastic products and the woodwork in building waste, and can to the material of large particle diameter, carry out abundant fragmentation substantially, save the broken time.
Because the space of contact surface between finished particle and ground is larger, the pressure that the position ground that causes contacting between finished particle ground bears is larger, thereby easily causes the region depression degree at frequent walking position larger.In order to address the above 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 obtains by the finished particle fragmentation in step (2), and the particle after fragmentation is less than 3cm.
When raining continuously or 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, can road pavement impact, thereby, in the roadside on People's Bank of China road surface, be provided with the aqueduct being communicated with finished particle place.Due to the setting of aqueduct, effectively discharge and be deposited in the ponding in finished particle, when not affecting this place, People's Bank of China road surface ecological, effectively guaranteed the discharge of ponding, effect is very remarkable.
As a kind of preferred, 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; Simultaneously can effectively reduce the sinking degree on face brick top layer, so can effectively avoid pedestrian to walk time ponding splash to it.
The specific embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
