Description

Technical Field

[0001] This utility model relates to the field of road prefabrication technology, specifically a quick-installation pavement prefabrication component for rural farmland roads. Background Technology

[0002] This patent describes a prefabricated pavement component widely used in rural farmland roads. The necessity of prefabricated pavement components for rural farmland roads is mainly reflected in the following four aspects: 1. Resolving the contradiction between funding and efficiency, and reducing long-term costs. Rural road construction faces the dilemma of large funding requirements, high flexibility, and uneven allocation. Customized prefabricated pavement components, through factory mass production, can reduce on-site construction time and labor costs, alleviate local financial pressure, improve the efficiency of fund utilization, and shorten the construction period. Compared with traditional cast-in-place roads that require a curing period, prefabricated components can be used immediately after installation; 2. Breaking through technical bottlenecks and ensuring standardized quality. The varying skill levels of construction teams in rural areas affect project quality. Precast components, produced using standardized factory processes (e.g., concrete strength, steel mesh reinforcement), ensure uniform component strength and avoid quality fluctuations caused by human error during on-site construction. 3. Precast road surface components, with their rapid repair and recyclability, help achieve road network upgrades. 4. Environmental and sustainability advantages: Precast road surface components reduce resource waste. Traditional construction generates large amounts of construction waste, while precast components are recyclable, significantly contributing to environmental protection.

[0003] The technical content described in this patent incorporates in-depth optimization and technological innovation based on factors such as actual construction sites, long-term road surface usage, and existing patent literature. For example, it references Chinese utility model patents 201120482256.2 (publication number CN20234738) entitled "A Precast Road Component Made of Asphalt Concrete" and 201520143102.9 (publication number CN204475099U) entitled "A Prefabricated Concrete Traffic Road Surface," both of which describe a precast road component with a bottom surface using... The structure adopts a planar design. This type of precast pavement component is practical for construction in urban roadbed conditions. However, when applied to rural field roads, the road durability is low due to limitations in the roadbed structure. In rural field road construction, there are no high requirements for vehicle load capacity and throughput. From an economic construction cost perspective, the roadbed material is mostly sand and gravel. During construction, the sand and gravel are compacted, the precast pavement component is placed on top, and finally, the gaps in the pavement section are sealed with grout, achieving rapid paving. However, the bottom surface of conventional precast components and the precast pavement components mentioned in the previous two patents is planar. During long-term use, road surfaces are frequently exposed to rainwater. After rainwater erosion, the sand and gravel in the roadbed loosens and collapses from both sides of the precast pavement component, leading to roadbed depletion and insufficient support for the pavement component. Ultimately, this prevents the precast pavement component from achieving long-term stable use. The inventor of this patented technology, taking into account the technological development in the field and the actual long-term use of roads, optimized the design concept and modified the product structure, thereby overcoming the aforementioned practical technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-installation pavement prefabricated component for rural farmland roads in order to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation prefabricated pavement component for rural farmland roads, comprising a prefabricated component body, characterized in that pins are symmetrically arranged on both sides of the lower end face of the prefabricated component body, and slots are opened in the roadbed lime-soil layer, wherein the pins are inserted into the slots.

[0006] Preferably, the upper surface of the precast road surface component is tapered from the center line of the upper surface to both sides.

[0007] Preferably, a sealing material injection joint is reserved at the joint end of two adjacent precast bodies; an injection reinforcement groove is opened at the upper part of the joint end of the precast body; a sealing material is placed in the injection reinforcement groove and the sealing material injection joint between two adjacent precast bodies, and the cross-section of the sealing material after curing is T-shaped.

[0008] Preferably, two or more sets of lifting bolt holes are symmetrically opened on the upper end face of the precast component body; lifting bolts or sealing nuts can be installed in the lifting bolt holes by thread; when the sealing nuts are installed in the lifting bolt holes, the upper end face of the sealing nuts is flush with the upper surface of the precast component body.

[0009] Preferably, the upper surface of the precast component body presents an arc-shaped surface that is high in the middle and low on both sides.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By adding inserts at the bottom as a waterproof barrier structure, the path of rainwater erosion is fundamentally blocked. Compared with traditional flat bottom designs (such as patents 201120482256.2 and 201520143102.9), it can reduce the loss rate of gravel in rural roadbeds by more than 90%, solving the chain reaction of damage caused by "rainwater-gravel loss-roadbed collapse-pavement failure".

[0012] 2. Sealing material injection joints are set in the precast pavement components, and the tiered clamping structure increases the firmness between the sealing material and the precast pavement components. To expedite the laying of the precast pavement components, lifting bolt holes are pre-drilled on them. After the pavement is hoisted and laid, sealing can be achieved simply by using sealing nuts, making the process convenient and quick.

[0013] 3. The technical content described in this patent aims to solve the environmental problems in the process of road construction and reconstruction without generating construction waste or damaging the soil quality; at the same time, when the road needs to be reconstructed or adjusted, agricultural farmland can be quickly restored.

[0014] 4. The upper surface of the precast component is an arc-shaped surface that is high in the middle and low on both sides. This shape is conducive to rapid drainage and prevents liquid from accumulating on the road surface in rainy weather. Attached Figure Description
