Description

Modular blind hole manufacturing system and modular blind hole manufactured thereby The present invention relates to a blind culvert, and more specifically, to a standardized modular blind culvert. Blind culverts, which are widely employed as a subsoil drainage method during civil engineering and landscaping projects such as road construction, railways, sports fields, and lawn plazas, are a drainage technique designed to maintain or enhance the inherent usability of facilities by ensuring stability. This is achieved by draining groundwater contained within soil pores through guide pipes (e.g., perforated pipes), thereby preventing soil erosion, improving soil durability, and promoting plant growth. In other words, as a gravity drainage method, it involves burying culverts to remove excess water contained in the subsoil layer; the culvert installation is performed by excavating down to the impermeable layer, burying permeable material, and then backfilling the top to drain the water contained in the subsoil. The construction of a conventional blind culvert constructed in this manner is completed by excavating the surface layer to the depth indicated on the design drawings, laying down non-woven fabric, spreading aggregate or crushed stone, installing perforated pipes on the non-woven fabric, and then spreading aggregate or crushed stone again on top to form a permeable layer to fill the culvert. Finally, the culvert is wrapped with non-woven fabric and backfilled to create the surface layer. In this case, the non-woven fabric functions as a filter to prevent soil particles from flowing in with water and clogging the perforated pipe due to soil conditions. Consequently, groundwater or water absorbed from the surface layer into the subsoil layer during rainfall passes through the non-woven fabric and the layer of crushed stone or aggregate, collects inside the pipe through the holes of the perforated pipe forming the drainage network, and is then drained through the pipe. These conventional blind drainage facilities had a problem in that the amount of crushed stone or aggregate input could increase more than necessary because the materials used during excavation were not standardized (modular), leading to over-excavation. In addition, there was a problem where stone dust was generated due to friction during the laying process of the crushed stone or aggregates, and if this dust absorbed water, it would harden over time, blocking the pores of the non-woven fabric and hindering proper drainage. In addition, repairs are required when drainage is not smooth due to clogging of the non-woven fabric after long-term use. However, since conventional blind drainage facilities have non-woven fabric wrapped in crushed stone or aggregate, repairs require the inconvenience of having to remove the entire blind drainage facility to repair it, and in reality, there is a problem of having to rebuild the entire facility.
