Do I need to set up telescopic seams on the permeable floor? How do you do that?

The concrete surface layer is composed of a certain thickness of concrete panel, which has the nature of hot expansion and cold shrink. As the temperature changes through the year, the concrete panels expand and contract to varying degrees.
to avoid these defects, concrete pavements have to have many seams in both directions

. Divide the whole road into many plates. The seams of concrete pavement can be divided into vertical seams and cross seams. Seams parallel to the middle line of a route are called vertical seams, and seams perpendicular to a route are called horizontal seams.
seam design requirements: 1. Control the position of cracks caused by shrinking stress and warp stress; 2. Provide sufficient load transfer through seams; 3. Prevent hard debris from falling into seam gaps.
, many people will ask, the permeable floor needs to set up telescopic seams? How do you do that?
professional permeable concrete manufacturer Guangda Ecological for you to answer: permeable floor needs to set up telescopic seams.
- when the strength of the permeable floor reaches about 70%, mechanical slits can be performed. The thickness of mechanical seams must meet the depth of the base. After cutting, the stone powder in the seam must be flushed with water in time to ensure that the seam is clean and dust-free, and the mud on the concrete surface caused by the seam is flushed clean. Permeable floor should be designed vertical and horizontal swelling.
the spacing of vertical seams should be determined according to the width of the road surface in the range of 4-5m, the
spacing of horizontal seams should be 5-6m; Fill the fill of the swelling with a extruded plate. (Reserved and cut by way)
- permeable concrete surface should be designed vertical and horizontal seams. The spacing of vertical seams should be determined according to the width of the road surface in the range of 3.0m to 4m, the spacing of horizontal seams should be determined in the range of 4m to 6m; The seam width is 2-3mm. When the grass-roots structure seam, the surface seam should be consistent with the corresponding structure seam position, and then inject the structure glue closed, embedded seam width is consistent, the surface is straight, good sense of view, so the requirements of the seam material must adhere to strong, good elasticity, adapt to the expansion and contraction of concrete, and insoluble in water, non-permeable water, aging, high temperature does not flow, low temperature does not crack. (The seam width is equal).
at the connection between the surface layer of the permeable floor and other structures such as side ditches, buildings, rainwater mouths, paved blocks, asphalt pavements, etc., a swelling shall be set up.
the permeable floor seams generally use the reservation method, made out of the seams can be through to the gravel layer. The surface shrink seam adopts the construction method of post-cutting, so that the extruded seam cut out is neat and beautiful. Everbright Eco recommends the use of toothless saw cutting, the specific cutting time should be depending on thickness, weather conditions, generally for paving within 3-7 days after completion of the cutting.
