detailed description

Below in conjunction with embodiment the utility model is described in further detail:

Example

As shown in Figures 1 to 3, a drainage type sidewalk structure includes base layer 5, concrete permeable layer 4, low-dose cement dry-mixed sand layer 2 and surface layer 1 from bottom to top, and concrete permeable layer 4 is determined by the porosity Constructed with 25% concrete, the concrete permeable layer 4 can store the water flowing down from the surface layer 1 and the low-dose cement dry-mixed sand layer 2 in sequence. The low-dosage cement dry-mixed sand layer 2 is constructed of mortar, the upper surface of the low-dosage cement dry-mixed sand layer 2 is parallel to the ground, and the low-dosage cement dry-mixed sand layer 2 can fill up the concrete permeable layer 4 so that it shows level, so as to install the face brick 15 at the level of the low-dose cement dry-mixed sand layer 2, to ensure the smoothness, level and appearance of the face brick 15 after installation, and the installation quality is higher. The surface layer 1 is composed of a drainage type facing brick cell 11 and a facing brick 15 installed in the drainage type facing brick cell 11. The drainage type facing brick cell 11 can extend infinitely along the drainage type sidewalk structure; the drainage type facing brick cell 11 can also be It is a unit, and the drainage type face brick cells 11 are sequentially laid on the drainage type sidewalk structure to form the surface layer 1 . The drainage type facing brick cell 11 includes a drainage frame 12 and a facing brick installation frame 13 evenly arranged in the drainage frame 12. As shown in FIG. frame structure, the drainage frame 12 is divided into several face brick installation frames 13 by the partition frame, and the drainage frame 12 has a drainage groove 14 connected with each other. The drainage groove 14 is composed of two parts, one part is arranged in the frame of the outer edge frame, and the other A part is arranged in the frame of the partition frame, and the drainage groove arranged on the outer edge frame communicates with the drainage groove arranged on the partition frame. The facing bricks 15 are tightly packed and installed in the facing brick installation frame 13 , as shown in FIG. 2 , each facing brick 15 is correspondingly installed in each facing brick installation frame 13 of the drainage type facing brick cell 11 .

As shown in Figure 1, a reverse filter layer 3 is provided between the low-dose cement dry-mixed sand layer 2 and the concrete permeable layer 4, and the reverse filter layer 3 is formed of a filter geotextile in a layered structure.

As shown in Figure 1, the middle part or/and the bottom of the concrete water-permeable layer 4 are provided with drainage pipes 41. During use, the surface layer 1 of the drainage type sidewalk structure is easy to accumulate water, and the water will easily accumulate after the surface layer 1 passes through the surface layer 1. Entering the low-dose cement dry-mixed sand layer 2, the low-dose cement dry-mixed sand layer 2 will also slowly discharge water through the reverse filter layer 3 to the concrete permeable layer 4, because the concrete permeable layer 4 is made of concrete with a porosity of 25%. Constructed, the water in the concrete permeable layer 4 can easily flow into the drain pipe 41, and the drain pipe 41 is connected with the rainwater well on the edge of the sidewalk, so that the water infiltrated from the surface layer 1 flows into the concrete permeable layer 4 , and then discharged into the rainwater well through the drainpipe 41, thereby preventing rainwater from causing soaking damage to the inside of the sidewalk.
