Generally, curbstones or sidewalk stones must be constructed before paving the asphalt layer. The construction method is as follows:
(1) When excavating the roadbed, firstly reserve the orientation of the stone next to the road to avoid repeated excavation time.
(2) Before the installation of roadside stone, the work to be done is as follows: (1) About the roadside stone with concrete foundation, the construction base is first (2) The roadside stone without concrete foundation is completely cleaned on site Thing.
2. Measure and stake out
According to the planned elevation and coordinate orientation of the stone beside the road, type the top elevation and orientation of the stone beside the road, and pull the rope. Put a point every ten meters. This point can be marked by the steel bar that hit the ground and hung on the steel bar with a wire rope. This lofting work should improve the accuracy, because it is related to the alignment of the asphalt pavement and the thickness and flatness of the asphalt pavement.
During the installation process, if the seam is required according to the planning requirements, the width of the seam should be reserved. The width should not be too large, and it should not be too small, about 1.5cm. Too wide a width is bad for mortar and working time. Too small a width will cause troubles for jointing work and also waste working time. Do not joint the stones next to the road, as this will slow down the work progress, and it is not easy to adjust if there is a problem with the elevation, but at this time, you must protect the road stones from being crushed. After the roadside stone is installed, the backrest of the roadside stone should be constructed in time. Because there is no seam at this time, it is easy to cause the roadside stone to fall.
This work is also best to use the decomposition process to speed up the progress. Mix M7.5 mortar. One person will smash the mortar into the reserved seam with a shovel in the front and compact it with a shovel. The other one will use the crocheted or 1cm diameter steel or wooden rod to smooth the mortar , Wipe the gap light, so that the surface of the gap is smooth, without water sacs, airbags or honeycombs.
Use mortar or 1cm diameter steel bars or wooden sticks to smooth the mortar.
5. Device adjustment
The edges of the curbstone and the stone beside the road should be linear, smooth, and bright, and the surface should be uneven and have a bad appearance. After a certain length of the device, visual inspection should be performed to adjust the irregularity of the line individually. After meeting the requirements of the plan, the cement concrete is backed with edge stone, and the width and height of the concrete are consistent with the plan.
After the mortar is cut, it should be cured in time.
