Embodiment 1

[0045] Such as image 3 As shown, the top surface of the prefabricated permeable bar 1 is flush with the top surface of the pavement brick, and coarse sand is filled in the permeable hole 11, so that the prefabricated permeable bar 1 is directly connected to the cushion from the surface layer, which can ensure The rainwater seeps down at the fastest speed, part of it flows into the roadside ecological side ditch along the cushion, and part of it continues to seep down to the soil foundation to replenish groundwater.

Embodiment 2

[0048] Such as Figure 5 Shown, the present invention also provides a kind of construction method of novel permeable sidewalk pavement, and it comprises the following steps:

[0049] S0, to ensure that the road bed compaction degree ≥ 90%;

[0050] S1. Pave the graded crushed stone or natural gravel cushion with a thickness of 10-15cm;

[0051] S2. The prefabricated permeable strips are positioned and inserted into the graded crushed stone or natural gravel cushion to a depth of 5-10cm;

[0052] S3, C20 cement concrete base is poured around the permeable strips, pay attention not to skew the prefabricated permeable strips;

[0053] S4. Meet the 7d compressive strength of the C20 cement concrete base, and lay cement mortar for the leveling layer;

[0054] S5. When paving pavement tiles, ensure that they are stable, free of warping and smooth on the surface.

[0055] Compared with the existing technology, the prefabricated permeable strips are used in the manufacturing and c...

Abstract

The invention discloses a prefabricated water-permeable strip block for paving a pavement. The prefabricated water-permeable strip block is of a long-strip-shaped structure with the depth capable of reaching a pavement paving structure cushion layer, embedding and locking portions for being connected with pavement face bricks are arranged on the side faces of the prefabricated water-permeable strip block, and a plurality of water-permeable holes are formed in the prefabricated water-permeable strip block. The water-permeable performance the same as or better than that of traditional water-permeable paving can be achieved, and manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of pavement of permeable sidewalks, in particular to a prefabricated permeable bar and a surface structure for pavement of sidewalks. Background technique [0002] With the rapid development of my country's urbanization process and the continuous expansion of urban scale, the construction of urban roads has been refreshed in front of our eyes with each passing day. Traffic, especially sidewalk construction, has become relatively weak. The floor tiles are loose and damaged, especially in rainy days, the sidewalks are seriously waterlogged, and if you don't pay attention, you will step on it and splash water. [0003] In urban construction, impermeable stone slabs and concrete are still the first choice for the pavement of urban streets, sidewalks, bicycle lanes, parks, courtyards and public squares in my country. The environment has had a negative impact. First of all, this kind of impermeable and airtight p...
