From a patent perspective, we will discuss the technology of permeable pavement pavement
从专利角度浅议透水路面铺装技术

摘要

随着“海绵城市”概念的提出和深入，城市建设越来越注重生态友好性、资源利用性，而在建设“海绵城市”中，透水路面铺装是实现雨水再利用、提高城市水资源储备和高效利用的重要分支之一。本文以透水路面铺装相关技术的专利数据作为基础，从国内专利申请量年变化趋势、主要专利技术概述以及重点申请人等方面进行了统计分析，就该领域相关技术近20年的发展概况进行简单梳理，旨在能为后续技术的研发方向提供参考。

Abstract

With the concept of "sponge city" put forward and deepened, urban construction pays more and more attention to ecological friendliness and resource utilization, and in the construction of "sponge city", per- meable pavement paving is one of the important branches to achieve rainwater reuse, improve urban water resource reserves and efficient utilization. Based on the patent data of permeable pavement pavement related technologies, this paper conducts statistical analysis from the annual change trend of domestic patent applications, the overview of major patent technologies and key applicants, and briefly sorts out the development profile of related techno- logies in this field in the past 20 years, aiming to provide reference for the research and development direction of subsequent technologies.
