Method for recycling concrete piles residue

Abstract

The present invention relates to a method for recycling concrete pile residue. According to the method of recycling concrete pile residue of the present invention, the residue is cut and processed according to its size and intended use. Large residue is recycled for purposes such as fence landscaping, earth retaining wall construction, embankment construction, flood control materials, and drainage construction, while small residue is utilized for various purposes such as paving blocks, flowerbed boundaries, and as a substitute for bricks. This allows high-strength concrete pile residue, which would otherwise be discarded at a cost, to be recycled as a regenerative resource. Furthermore, it can prevent transportation and disposal costs for construction waste treatment, as well as pollution and environmental destruction caused by landfilling. Additionally, it can reduce environmental damage and resource depletion issues associated with the extraction of aggregates used as raw materials for the production of new concrete piles, as well as the economic burden resulting from rising raw material costs.

Description

Technology Field

[0001] The present invention relates to a method for recycling concrete pile residue. Background Technology

[0002] Concrete piles are high-strength concrete piles primarily used for foundation work to reinforce soft ground at apartment construction sites, and are commonly referred to in the industry as PHC piles (Pretensioned spun High-Strength Concrete Pile).

[0003] Recently, pile foundations are the most commonly used foundation methods at construction sites, and the driven pile method, which offers relative advantages in terms of noise and vibration, is also frequently used. Currently, prior to the construction of a building structure, steel pipe piles are driven into the ground using a pile driver to reinforce the soil, or concrete piles are installed by drilling holes in the ground at regular intervals down to the bedrock using a crane and a drill. However, due to differences in the height of the bedrock beneath the ground, concrete piles must be cut to align with the level line of the building structure, leaving behind residual concrete piles. While steel pipe piles are currently recycled as scrap metal, the residual concrete piles, despite containing high-strength steel cores and high-strength concrete, are crushed by an excavator crusher. Although the steel cores are recycled, the crushed concrete piles must be transported by vehicle and disposed of as construction waste, thus failing to provide an opportunity for recycling. Consequently, there are issues regarding transportation and disposal costs for construction waste, as well as pollution and environmental destruction resulting from the landfilling of construction waste. Furthermore, there are problems such as environmental destruction and resource depletion resulting from the extraction of aggregates used as raw materials for the production of new concrete piles, as well as additional economic burdens caused by rising raw material costs. The problem to be solved

[0004] This invention was developed to solve the aforementioned problems. Accordingly, the purpose of this invention is to recycle high-strength concrete pile residue, which is currently discarded at a cost, into a renewable resource. This is achieved by cutting and processing the massive amount of concrete pile residue generated after pile driving at the building level line, according to size and intended use. Large residue can be recycled for purposes such as fence landscaping, earth retaining wall construction, embankment construction, flood control, and drainage construction, while small residue can be utilized for various purposes such as paving blocks, flowerbed boundaries, and as a substitute for bricks. means of solving the problem

[0005] To achieve the above objectives, the present invention provides a method for recycling concrete pile residue, and more specifically,

[0010] The step of cutting and processing concrete pile residue consists of a process of cutting and processing the concrete pile residue into large pieces using concrete cutters and processors to suit recycling purposes such as fence landscaping, earth retaining work, embankment construction, flood control materials, and drainage construction, and a process of cutting and processing the concrete pile residue into small pieces suitable for recycling purposes such as paving blocks, flowerbed boundaries, and brick substitutes, thereby providing a method for recycling concrete pile residue that enables recycling in various fields and for multiple purposes.

[0027] In addition, a step of cutting and processing the concrete pile residue (101) according to its intended use, and then painting it according to its intended use, may be performed.

[0028] As described above, according to the concrete pile residue recycling method of the present invention, large concrete residues, which are cut and processed according to size and intended use, can be recycled for purposes such as fence landscaping, earth retaining work, embankment construction, flood control, and drainage work, while small concrete residues can be used for various purposes such as sidewalk blocks, flowerbed boundaries, and as substitutes for bricks, thereby enabling the recycling of high-strength concrete pile residues, which would otherwise be discarded at a cost, into regenerated resources.

[0029] Furthermore, it prevents transportation and disposal costs for construction waste, as well as pollution and environmental destruction caused by landfilling. Additionally, it can reduce environmental damage and resource depletion issues associated with the extraction of aggregates used as raw materials for the production of new concrete piles, as well as the economic burden resulting from rising raw material costs.
