近年来,随着公路建设的迅猛发展,我国高级公路的建设,在设计与施工方面也取得了很大的进步;采用先进的勘察、测量手段为公路路基设计提供了可靠技术资料。对公路路基综合稳定技术的研究,研制出了一大批用于路基工程的新材料:土工布、土工格栅、高强度塑料网、塑料排水板、加劲软式透水管、软硬塑料排水管、草坪植生带、轻质填料等;新型工程机械:大吨位振动压路机、加固土拌和机、塑料排水板插板机、土工布沉铺机、深层粉体搅拌成桩机;新技术、新方法:粉体搅拌法、塑料排水板法、锚固技术、喷锚支护、轻质路堤、网箱席垫、加筋等技术,得到了充分的开发和引进,以及为这些新技术服务的各类专业化施工公司应运而生,专业化施工公司的建立和发展,为路基工程专项施工奠定了基础。
In recent years, with the rapid development of highway construction, the construction of highways in our country has also made great progress in the design and construction. The advanced survey and measurement methods have provided reliable technical information for highway subgrade design. A large number of new materials for roadbed engineering have been developed for the comprehensive stability of highway subgrade: geotextile, geogrid, high-strength plastic net, plastic drainage board, stiffened soft water permeable pipe, hard and soft plastic drainage pipe, Lawn vegetation belt, light packing, etc .; new construction machinery: large tonnage vibratory roller, reinforced soil mixing machine, plastic drain board flapper, geotextile disintegrator, deep powder mixing pile driver; new technologies and new methods: Powder mixing method, plastic drainage board method, anchoring technology, spray anchor support, light embankment, cage mats, reinforcement and other technologies, has been fully developed and introduced, and for these new technologies and services of various types of professional The construction company came into being, the establishment and development of specialized construction company, laid the foundation for the special construction of roadbed project.
