Surface inlet for use with passive textile-covered water reservoirs for tree irrigation

Abstract

The infiltration box is characterized by a diffusion-open connection between a dimensionally stable, fabric-covered water reservoir in the ground and the surface; fluids can penetrate the ground more quickly through the openings of the infiltration box from traffic areas and green spaces.

Description

Current state of the art:

[0001] Current methods of passive irrigation for tree plantings, including plastic split cylinders and aeration pipes, as well as textile-covered water reservoirs, are placed in the unsealed areas of the tree pit. This aims to drain surface water into the soil and promote soil gas exchange. Split cylinders and textile-covered water reservoirs can be installed in existing tree pits without significant effort, whereas the plastic aeration pipes require more complex installation. Due to the high cost, these solutions are not currently used in traffic areas within tree pits, such as cycle paths. Furthermore, split cylinders and textile-covered water reservoirs can lead to soil compaction and overgrowth of surface vegetation over time.This reduces the beneficial functions of the water reservoirs. Due to the slow rate of water infiltration into the soil, a large proportion of the water is lost, and the introduced water is only slowly available to the plants. The water takes a long time to reach the necessary depths to the root system. A significant amount of water is lost through evaporation.

[0002] The invention achieves that, in textile-covered water reservoirs, the water introduced into the soil is available to trees / plants after a short period and its function is permanently enhanced (claim 1). The previous problem that textile water reservoirs cannot be used in traffic areas is solved by this infiltration box. A permanent connection to the surface can be ensured, and the sealed parts of the tree pit can be used for water and soil gas exchange. Depending on the load requirements, the infiltration box can be manufactured from metallic and non-metallic materials as a permanent solution (claim 7). This promotes sustainability through low maintenance and repair costs.

[0003] The versatility of the system is ensured by the ability to adapt the geometric shape to the corresponding installation method; its shape and external dimensions allow it to be integrated into existing paved and green areas without major effort.

[0004] To prevent contamination of the soakaway box, a debris trap is installed. This trap can be accessed and emptied by opening the soakaway box. This debris trap is advantageously used within the system to attach the textile water reservoir to the soakaway box via a clamp connection. Water can then drain into the reservoir through the opening in the textile. If no debris trap is used, the water reservoir can be attached to a ledge on the system lid using a drawstring.

[0005] To prevent vertical displacement of the drainage box once installed, the lower bearing surface has been enlarged. A circumferential rim prevents it from sinking into the ground. This rim is designed so that surface coverings can be directly connected to the drainage box.
