Embodiment 1

[0055] Embodiment 1; as Figure 1 to Figure 8 ,as well as Figure 17 to Figure 21As shown, on the sidewalk 10 to be constructed, a foundation pit 101 with a predetermined depth and width is dug according to the drawings, and the soil foundation at the bottom of the foundation pit 101 is compacted, and the structures of the curb 102, the retaining wall 70 and the seepage well 702 are as required After the masonry is completed, the distance between the water retaining walls 70 is determined according to the slope of the sidewalk 10. When the slope is larger, that is, the angle of inclination is larger, the distance between the water retaining walls 70 is smaller. The design can avoid that the actual water capacity of the water-holding foundation pit 101 formed between the water-retaining walls 70 will be reduced if the distance between the water-retaining walls 70 is too far. Step 703; then fix the obliquely arranged plastic pipe 701 by cement mortar on the upper part of the wa...

Embodiment 2

[0063] Embodiment 2; as Figure 1 to Figure 7 ,as well as Figure 9 to Figure 21 As shown, compared with Embodiment 1, the difference of this embodiment lies in the difference in the structure of the permeable brick 60 and the same construction steps, which will not be repeated in this embodiment.

[0064] After the permeable horizontal plate 50 is laid, a hard hollow porous brick 60b is laid on the permeable horizontal plate 50. The hollow porous brick 60b here is provided with a rectangular cavity, and the cavity runs through the hollow porous brick 60b. And a cross support frame 604 is provided in the rectangular cavity. In this embodiment, it is preferably a cross support frame 604 connecting the diagonals of the rectangular cavity. The cross support frame 604 divides the cavity porous brick 60b into four parts. , that is, the accumulated water directly penetrates downward from the non-supporting frame 604 part of the rectangular cavity to the permeable horizontal plate 5...

Embodiment 3

[0069] Embodiment 3; as Figure 1-Figure 7 ,as well as Figure 9 to Figure 21 As shown, the difference between this embodiment and Embodiment 2 is that the cavity permeable brick 60 and the permeable surface brick 60c are integrated, so that the design does not require additional bonding construction of the permeable surface brick 60c, and the connecting rod 405 uses a tool from the third through hole Pull it out at 606 and tighten it. The other features of the two are the same, so I won’t go into details here. Of course, the permeable brick 60 also has other similar structural deformations. Change the plane into an uneven surface, and then play the role of wear resistance and anti-skid, so that it can be applicable to the sidewalk 10 in parks or gardens; or the solid porous brick 60a also offers the groove 605 on the side of the cavity porous brick 60b With the fourth through hole 603, this design can also increase the water permeability of the permeable brick 60, etc. For t...

Abstract

The invention belongs to the field of road construction in urban construction and provides a subgrade construction method for a sidewalk water-permeable brick and the water-permeable brick. Through base construction, curb, water-retaining wall and seepage well structure construction, bearing layer construction, water-permeable brick wall pavement construction, handrail structure construction, joint repair and maintenance construction, hard and perforated water-permeable flat plate and water-permeable brick combination and matching of self structure characteristics, the subgrade construction method can solve the problems that a paving structure of an existing sidewalk brick cannot realize the combination of strength and high permeability, the freezing-thawing resistance is bad, and the maintenance is inconvenient and uneconomical.

Description

technical field [0001] The invention belongs to the field of road construction in urban construction, and in particular relates to a subgrade construction method of permeable bricks for sidewalks and permeable bricks. Background technique [0002] Sidewalk bricks are widely used in sidewalks, squares and other places. According to different materials, the existing permeable brick laying and installation surfaces generally include clay bricks, concrete permeable bricks, sand-based permeable bricks and ceramic permeable bricks; among them, the strength of clay bricks is good, and The surface can absorb water slightly, but the water will overflow from the brick surface after absorbing and saturating. After a long time of use, the brick surface will be prone to moss, making the brick surface very slippery; while the concrete permeable brick has larger pores in the same material and is more permeable. The higher the rate, the lower the corresponding strength, and it is difficult ...
