Description

Technical Field

[0001] This invention relates to the field of purification, and in particular to a permeable curbstone for road isolation strips made from construction waste and its processing technology. Background Technology

[0002] Permeable curb stones for road medians are important municipal infrastructure, serving not only to separate lanes and guide traffic, but also playing a crucial role in road drainage and landscaping. However, traditional curb stones have many limitations in structural design, material application, and construction efficiency, making it difficult to meet the higher requirements of modern urban road construction. Common curb stones are mostly made of solid concrete, which has poor permeability and cannot effectively drain water from the road surface. In rainy areas, rainwater tends to accumulate around the road median, which not only exacerbates road erosion and shortens the service life of the curb stones, but also poses traffic safety hazards. Although some improved curb stones attempt to add drainage holes, they often suffer from low drainage efficiency and easy clogging, making it difficult to form an efficient and stable drainage system.

[0003] Traditional curb stones rely heavily on their own weight for fixation, lacking effective anti-overturning and anti-displacement designs. Under long-term vehicle loads and soil pressure, they are prone to deformation or displacement, affecting the overall stability of the median strip. This problem is particularly prominent in high-traffic roads, leading to a significant increase in maintenance costs. Furthermore, traditional curb stones primarily rely on natural aggregates, consuming large amounts of natural resources and imposing a significant environmental burden during production. With the continuous increase in construction waste, how to achieve resource utilization of construction waste has become a crucial issue urgently needing to be addressed by the industry. Although there have been studies attempting to produce curb stones using recycled aggregates, issues such as low strength and unstable composition of recycled aggregates often make it difficult to guarantee product quality. Moreover, traditional curb stones are mostly produced using monolithic casting or simple splicing methods, resulting in low installation efficiency and poor joint precision. Especially in projects that require flexible adjustments to road layout, traditional curb stones are clearly not adaptable enough, increasing construction difficulty and time. In addition, the existing curb stone production process is relatively backward, mostly using fixed molds for molding, making it difficult to achieve one-time molding of complex structures. The precision and consistency of products need to be improved, and the maintenance process also relies heavily on natural curing, resulting in long production cycles and low efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a permeable curbstone for road isolation strips of construction waste and its processing technology, which can effectively solve the technical problems raised in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A permeable curbstone for road isolation strips in construction waste includes a curbstone body and curbstone protrusions. The curbstone protrusions are located on both sides of the curbstone body. The rear end of the curbstone body has multiple integrally formed extended reinforcing blocks. The lower end of each extended reinforcing block is fixedly installed with a support and reinforcement rod. The interior of the curbstone body has a drainage groove. Both sides of the curbstone body have a body docking groove. Both sides of the curbstone protrusions have protrusion docking grooves. A docking insert is provided between the curbstone protrusions and the curbstone body.

[0007] Preferably, the supporting reinforcement rods extend downward to the bottom of the curbstone body, and the multiple supporting reinforcement rods are arranged in a straight line.

[0008] Preferably, a main water collection base is placed at the lower end of the curbstone body, and a protrusion water collection base is placed at the lower end of the curbstone protrusion, with the main water collection base and the protrusion water collection base being fitted and connected together.

[0009] Preferably, the drainage channel extends to the bottom surface of the curbstone body, and the drainage channel is connected to the interior of the main body's water collection base.

[0010] Preferably, the mating block is inserted into the main body mating groove and the protrusion mating groove, and the curbstone main body and the curbstone protrusion are fixedly connected by the mating block.

[0011] A processing technology for permeable curb stones used in road medians for construction waste, the technology specifically includes the following steps:

[0012] Step 1: Raw material preparation. The construction waste is crushed and screened to obtain recycled aggregate with a particle size range of 5-40mm.

[0013] Step 2: Mixing and Batching. Mix the recycled aggregate with cementitious materials, water and admixtures in a predetermined ratio to form a homogeneous concrete mixture.

[0014] Step 3: Mold preparation and use of custom molds. The molds have internal structures that correspond to the main body of the curbstone, the curbstone protrusions, the drainage grooves, the main body docking grooves, and the protrusion docking grooves.

[0015] Step 4: Casting and shaping: Pour the concrete mixture into the mold, compact it with vibration, and let it stand to form the initial blank of the curbstone body and the curbstone protrusions;

[0016] Step 5: Curing and Demolding. After demolding, the molded product undergoes standard curing. The curing environment temperature is controlled at 15-25°C and the humidity is greater than 90%. The curing time is no less than 7 days.

[0017] Step Six: Assembly and Integration. Connect the main body of the curbstone to the curbstone protrusions using mating blocks, and install the main body water collection base and the protrusion water collection base, ensuring that the drainage channel and the water collection base are internally connected.

[0018] Preferably, in step one, the construction waste includes at least one of waste concrete, bricks, or ceramic materials. After crushing, it is screened to obtain aggregates of different particle sizes. Stabilizers are added as needed to improve the strength of the aggregates. The construction waste is automatically sorted using image recognition or sensor technology to improve the purity of the recycled aggregates. At the same time, materials such as silica fume and polymer fibers are added to enhance the strength and durability of the aggregates.

[0019] Preferably, in step three, a mold is customized using 3D printing technology. The mold design includes detachable protrusions for directly forming drainage channels, main body docking channels, and protrusion docking channels during molding. The mold material is made of steel and composite plastic.

[0020] Preferably, in step five, the maintenance process adopts steam curing and natural curing methods, and the curing time is adjusted according to environmental conditions, with a curing time of 7-14 days, in order to enhance the compressive strength and permeability of the curbstone.

[0021] Preferably, in step six, during assembly, the extension reinforcing block and the support reinforcing rod are first integrally formed with the curbstone body, and then fixed by inserting the mating block into the mating groove of the body and the mating groove of the protrusion, so as to ensure that the overall structure of the curbstone is stable and the drainage is smooth.

[0022] The beneficial effects achievable by the above embodiments of the present invention include: the drainage channel inside the curbstone body is connected to the main body water collection base and the protruding water collection base to form an efficient drainage system. Rainwater or road surface water can quickly seep into the drainage channel and be concentrated and guided to the water collection base, avoiding the erosion of the road median strip by accumulated water and improving road safety. The drainage channel runs through the bottom surface of the curbstone to ensure unobstructed water flow. The water collection base adopts a close-fitting connection design to prevent leakage. This structure is particularly suitable for rainy areas, reducing the risk of road surface water accumulation, extending the service life of the curbstone, reducing maintenance costs, and giving the curbstone excellent permeability and drainage efficiency.

[0023] The extension reinforcement block and the support reinforcement rod are integrally formed into the main body of the curbstone, providing additional support and preventing the curbstone from deforming under vehicle load or soil pressure. Multiple support reinforcement rods are arranged in a straight line to further disperse the pressure. The support reinforcement rods extend downward and insert into the soil to form an anchoring effect. The extension reinforcement block increases the contact area and improves the overall rigidity. In conjunction with the addition of silica fume and polymer fiber modified aggregates in the processing technology, the compressive strength is increased by more than 20%, giving the curbstone enhanced structural stability and compressive strength. It is suitable for high-traffic roads and ensures the long-term stability of the median strip.

[0024] The main body docking groove and the protrusion docking groove are quickly connected by docking blocks, realizing the precise assembly of the curbstone body and the curbstone protrusion. The modular design allows for flexible adjustment of length and shape to adapt to different road layouts. After the docking blocks are inserted into the grooves, a fixed connection is formed, reducing installation time, facilitating operation by construction personnel, shortening the construction cycle, reducing human error, and making it particularly suitable for expressway projects, thus improving project efficiency.

[0025] Using construction waste as recycled aggregate reduces the consumption of natural resources and the pressure on landfills. Intelligent sorting through image recognition or sensors improves aggregate purity and reduces environmental pollution. Adding stabilizers to the recycled aggregate particle size ensures enhanced strength and durability, meeting the requirements of the circular economy, reducing production costs, improving product green certification, contributing to urban sustainable development, and aligning with environmental policy guidelines. At the same time, the processing technology uses 3D printing customized molds and a controllable maintenance system to ensure product precision and consistency. The detachable protrusions of the mold directly form complex structures, reducing processing scrap rates, improving production efficiency, and ensuring the permeability and strength of the curbstone.

The mold material is made of steel and composite plastic.

[0050] In this embodiment, in step five, the maintenance process adopts steam curing and natural curing methods. The curing time is adjusted according to environmental conditions, ranging from 7 to 14 days, in order to enhance the compressive strength and permeability of the curbstone.

[0051] In this embodiment, in step six, during assembly, the extension reinforcing block 2 and the support reinforcing rod 3 are first integrally formed with the curbstone body 1, and then the mating plug 8 is inserted into the main body mating groove 5 and the protrusion mating groove 7 for fixation, so as to ensure that the overall structure of the curbstone is stable and the drainage is smooth.
