Embodiment

[0028] The technology for laying lattice pavement is characterized in that it mainly consists of the following steps:

[0029] (1) After the foundation is compacted, lay steel strips with a grooved cross-section on the foundation, and then fill between the two steel strips with massive gravel; the height of the steel strips is greater than 15cm, and the steel strips are A through hole is provided and a layer of geotextile is laid in the groove of the steel bar, the size of the massive crushed stone is less than 10cm, and the laying thickness of the massive crushed stone is greater than 20cm;

[0030] In order to reduce the pressure on the foundation caused by laying massive gravel directly on the foundation, a layer of gravel not larger than 3cm in size is laid between the massive gravel and the foundation, and the thickness of the laid gravel is 5 cm. ~10cm.

[0031] In this embodiment, the blocky gravel is preferably about 6 cm pebbles, and the paved thickness is preferably...

Abstract

The invention discloses a process for paving a latticed pavement of a pedestrian walkway. The process mainly comprises the following steps of (1) paving steel bars with groove-shaped sections on a foundation after tamping the foundation, and then, filling lumpy macadam between every two steel bars, wherein the height of each steel bar is not smaller than 15cm, through holes are formed in each steel bar, a layer of geotechnical cloth is paved in the groove of each steel bar, the size of the lumpy macadam is not larger than 10cm, and the paving thickness of the lumpy macadam is not smaller than 20cm; (2) after finishing the operation of paving the lumpy macadam, paving more than one layer of geotechnical cloth between every two adjacent steel bars, and fixing the ends of the geotechnical cloth on the steel bars; and (3) after finishing the operation of paving the geotechnical cloth, paving a layer of fine sand with the thickness of 10-20cm on the geotechnical cloth, and paving face bricks on the fine sand by using concrete after finishing the operation of paving the fine sand. The process has the advantages of rapidly draining water and reducing uneven conditions caused by different subsidence degrees at different positions of the layer below the face bricks.

Description

[0001] technical field [0002] The invention relates to a pavement paving method, in particular to a lattice pavement paving process. Background technique [0003] Sidewalk (side walk; foot way) 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. [0004] 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 sid...
