毛主席教导我们:“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上。因此,人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进。”公路桥梁钻孔灌注桩的新工艺,是在群众打井的传统方法基础上,经过交通系统职工几年来的苦心钻研,不断试验总结,逐步改进,逐渐丰富起来的,目前各地、各单位(包括其他部门)正在大力推广使用。由于这个新工艺适用范围广,且有广大群众基础,因此不但专业施工队伍应用了,而且已经有不少县的交通部门、公社生产队的农民群众,也成功地使用了这个方法,修建了不少的地方道路桥梁和农村桥梁,这对支援农业起了一定作用,意义是重大的。钻孔灌注桩新工艺,最近已经交通部作了技术鑑定。它的主要优点是,既提高了承载能力,保证了质量,又节约了钢材木料,避免了围水、抽水、挖基、沉井、打桩等繁重工作,以简便的锥具代替了笨重设备,基础工程的造价下降20～50％;更由于可以每个墩台,甚至每个桩平行作业,大大缩短了工期,有利于急要工程的抢修。这是公路桥梁施工上的重大技术革新,是公路桥梁施工方面体现多快好省的新工艺。它的设计和施工方法,我们已在本刊第6期作了介绍,现在继续刊登黑龙江省等地使用情况和经验。这是他们在推广使用中,根据不同条件,不断改进,日益丰富和发展起来的成果。人类对自然界的认识是无穷无尽的。我们相信,在毛泽东思想的光辉照耀下,在生产新高潮中,有关这方面的好经验,一定会在实践中不断地创造出来。希望各地区,各单位及时总结,陆续给本刊写稿,以便及时地、广泛地交流,互相促进,共同提高!
Chairman Mao taught us: “In the struggle for production and within the scope of scientific experiments, mankind always develops continuously, and the nature always develops continuously and never stops at a level. Therefore, mankind always has to sum up experiences and experience Found that some inventions, have created, some progress. ”Highway bridge bored piles of new technology is drilling in the masses based on the traditional methods, after years of painstaking research by employees in the transport system, continuous experimental summary, Gradually improve, gradually enriched, at present, all units, including other departments are vigorously promote the use of. Due to the wide scope of application of the new technology and its broad popular base, not only the professional construction team has been applied, but also many of the county’s transport departments and peasant masses of the commune production team have successfully used this method to construct a Less local roads and bridges and rural bridges, which play a role in supporting agriculture, the significance is significant. Bored piles of new technology, the Ministry of Communications recently made a technical appraisal. Its main advantage is that it not only improves the carrying capacity, ensures the quality, but also saves the steel lumber, avoids heavy work such as surrounding water, pumping water, digging foundation, caisson and piling, replacing bulky equipment with simple cone, The cost of basic projects will be reduced by 20% to 50%. Moreover, as each pier or even one pile can be operated in parallel, the construction period will be greatly shortened, which will be conducive to the repair of urgent projects. This is a major technological innovation in the construction of highway bridges and bridges and is a new process that shows how fast and good highway construction can be accomplished. Its design and construction methods, we have introduced in the sixth issue, now continue to publish the use and experience of Heilongjiang Province. This is their promotion in use, according to different conditions, continuous improvement, increasingly rich and developed results. Human understanding of nature is endless. We believe that with the brilliant shining of Mao Zedong Thought and the new upsurge of production, good experiences in this regard will certainly continue to be created in practice. We hope that all regions and units will summarize in time and write the manuscripts one after another so that they can exchange and promote each other in a timely manner and enhance each other jointly.
