Embodiment
[0032] Sandstone waste sidewalk construction technology is characterized in that it mainly consists of the following steps:
[0033] (1) Screening treatment: Use screening equipment to screen sand particles with a fineness modulus less than 3.7 from construction waste.
[0034] Selection and separation: use magnetic separation to select iron products from the remaining construction waste; then put the selected construction waste into salt water, and use the buoyancy of the salt water to select wood and plastic from the construction waste, and finally Other metal products are sorted out from construction waste by manual methods.
[0035] Among them, the selected metal products can be sorted, recycled and recast, such as aluminum alloy, copper, color steel, iron products, stainless steel, etc. After being screened out in this step, they are transported to the garbage recycling station, where they are recycled and reused . And the plastic products in this step are also transpor...

The invention discloses a gravel waste sidewalk construction process. The gravel waste sidewalk construction process comprises the following steps: (1) screening and sorting, (2) crushing construction waste into finished particles being less than 10cm; (3) paving steel bars with groove-shaped sections on the tamped foundation and then putting the finished particles between the two steel bars in a filling manner, wherein the height of each steel bar is greater than 15cm, a through hole is formed in each steel bar and a layer of geotechnical cloth is paved in the groove of the steel bar; (4) after finishing the paving of the finished particles, paving more than one layer of geotechnical cloth between the two adjacent steel bars and fixing the end parts of the geotechnical cloth to the steel bars; (5) after finishing the paving of the geotechnical cloth, paving a layer of sand by 10cm-20cm on the geotechnical cloth, and paving face bricks on the sand by use of concrete after finishing the paving of the fine sand. The gravel waste sidewalk construction process has the advantages of material cost saving, environmental protection, quick drainage, the reduction of unevenness possibility due to different subsidence degrees of lower layers of the face bricks, and the like.
Description
technical field [0001] The invention relates to a pavement laying method, in particular to a sandstone waste sidewalk construction process. Background technique [0002] Sidewalk (sidewalk; footway) refers to the part of the road that is separated by curbs or guardrails and other similar facilities for pedestrians. Sidewalks are very common in cities, and there are usually sidewalks next to the streets. In some places, the sidewalk and the motorway are separated by grass or trees. [0003] Streets, also known as continuous building groups in cities, refer to the part from the curb and curb (flowing stone) marking the boundary of the roadway to the part where the base line of the house is higher than the roadway, which is exclusively for pedestrians. Illegal occupation is prohibited, and Vehicles driving in, but pushing bicycles to walk on the sidewalk or disabled persons shaking wheelchairs to pass on the sidewalk shall be treated as pedestrians. The cut-off part of the s...
