Problems solved by technology

[0004] Some existing non-permeable roads and squares, in the face of sudden heavy rainfall, often have a relatively large amount of water accumulated on the roads and squares, and the runoff of rainwater is large, which cannot be infiltrated on the spot. In addition, it cannot be discharged in time. Causes the road area to rise, so there are certain improvements

Embodiment 1

[0035] Such as figure 1 As shown, a road and square structure that facilitates water seepage is set above the ground. In response to the country's proposal to build a "sponge city", when upgrading the urban drainage system, priority should be given to retaining limited rainwater and more use of natural forces to drain water, so as to build an environmentally friendly sponge city with natural accumulation, natural infiltration, and natural purification.

[0036] The road and square structure of this application can discharge the accumulated water on the road or square in time and infiltrate it below the ground surface in the face of sudden heavy rainfall, so as to prevent the occurrence of accumulated water to a certain extent and realize environmental protection accordingly demand for a sponge city.

[0037] Specifically, the road and square structure includes plain soil tamping layer 1 , foundation gravel layer 2 , bonding layer 3 and permeable surface layer 4 . The plain s...

Embodiment 2

[0049] A construction method for roads and square structures that is convenient for water seepage, comprising the following steps:

[0050] S100, forming a compacted plain soil layer 1 by compacting plain soil on the surface, and the compaction degree of the compacted plain soil layer 1 is not less than 93%;

[0051] S200, the insertion end 51 of the seepage pipe 5 is cut into a spike shape, the opening of the insertion end 51 of the seepage pipe 5 is sealed and sealed, and the side wall of the insertion end 51 of the seepage pipe 5 is circumferentially opened with water seepage holes 53 communicating with the interior thereof, a plurality of The seepage pipes 5 are evenly distributed on the plain soil compacted layer 1 at intervals of 4 meters, and the insertion ends 51 of the seepage pipes 5 are pressed and inserted into the loose seepage layer of the plain soil compacted layer 1, and the distance between the loose seepage layer and the plain soil compacted layer 1 The surfa...

Abstract

The invention discloses a road and square structure convenient for water seepage and a construction method. The key points of the technical scheme are that the structure comprises a rammed plain soillayer, a basic gravel layer located on the rammed plain soil layer and a bonding layer located on the basic gravel layer, a permeable surface layer is arranged on the bonding layer, and a plurality ofhollow water seepage pipes are pressed in and inserted in the rammed earth layer and are evenly arranged at intervals; one end of each water seepage pipe is an insertion end, and the other end is a drainage end; the insertion ends of the water seepage pipes are inserted into a loose water seepage layer of the rammed earth layer, and the drainage ends of the water seepage pipes are flush with thesurface of the bonding layer. The system has the characteristics that the on-site water seepage is facilitated, the rainwater is guided into an underground soil layer, the rainwater runoff is reduced,and the water accumulation on roads and squares is prevented; in addition, the compactness of the rammed earth layer is increased to a certain extent.

Description

technical field [0001] The invention relates to the technical field of road structures, in particular to a road, a square structure and a construction method that are convenient for water seepage. Background technique [0002] With the development of industrialized cities and the increase of urban traffic vehicles, they are highly transparent to visible light from solar radiation, and highly absorptive to long-wave radiation emitted by the earth, which can strongly absorb infrared rays in ground radiation, causing the earth's temperature to rise. Rise, resulting in a greenhouse effect, increased global rainfall, and redistribution of precipitation. [0003] For this reason, the state proposes to build a "sponge city", the purpose of which is to give priority to retaining limited rainwater when improving the urban drainage system, reduce rainwater runoff, give priority to using more natural forces to absorb rainwater, and build natural accumulation, natural infiltration, An ...
