Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing paved road surfaces with low adhesion coefficients, such as basalt brick or tile brick roads, often result in uneven surfaces due to uneven roadbeds and surfaces, leading to inaccurate experimental data during testing.
Innovation Solution
A top-down construction type assembly method for paved road surfaces, involving the manufacturing of prefabricating slabs using a top-down method with threaded sleeves, and a precise mounting process including altitude and position fine-tuning, followed by grouting to ensure evenness and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If prefabricating blocks are directly laid on the road surface after preparation, then construction efficiency is improved, but road surface evenness deteriorates due to uneven roadbed and road surface
Solution Approach 1:
The patent applies preliminary action by preparing and pre-leveling the roadbed and road surface before laying the prefabricating blocks. The roadbed is leveled and compacted in advance, and the road surface is prepared with proper gradient and evenness before block installation, ensuring that the blocks are laid on a uniform base rather than directly on uneven ground
Solution Approach 2:
The patent segments the construction process into distinct phases: roadbed preparation and leveling, road surface preparation, block laying, and joint filling. This segmentation allows each phase to be optimized independently, with the roadbed and surface prepared separately before block installation, improving both efficiency and precision
2Device complexity
If conventional paving methods are used, then construction simplicity is maintained, but experimental data accuracy deteriorates due to uneven water film formation
Solution Approach 1:
The patent applies preliminary action by pre-leveling the roadbed and preparing the road surface with proper gradient and evenness before laying the prefabricating blocks. This preliminary preparation ensures that when blocks are installed, they form a uniform surface that produces accurate experimental data during testing
Solution Approach 2:
The patent implements feedback by checking and adjusting the road surface evenness during the construction process. The gradient and surface uniformity are monitored and adjusted before block laying to ensure that the final surface will produce accurate experimental data, allowing for corrective actions if deviations are detected

AI summary
A top-down construction type assembly construction method for paved road surface, including the following steps: step I, manufacturing prefabricating slabs: using a top-down method to manufacture the prefabricating slabs, and providing bolt sleeves, inside the prefabricating slabs, which are evenly arranged in the prefabricating slabs; step II, mounting the prefabricating slabs: on a lower bearing plate, placing the prefabricating slabs in one step, performing a fine tuning on a position and an altitude of the prefabricating slabs, performing a grouting construction, finally forming the paved road surface; the prefabricating slabs are manufactured by laying bricks and pouring concrete, the prefabricating slabs are rolled over and mounted, thus eliminating on-site concrete bonding between bricks and the lower bearing plate, improving overall stability of the bricks and the prefabricating slabs after being mounted, assembled mounting for a paved road surface is implemented, and the construction period is shortened.
