钻孔灌注混凝土桩是一项符合多快好省的新工艺,是重大的技术革新。它在我国当前工程建设中发展迅速。交通部门用这种方法完成公路桥梁总长300O延米;水利建设上河南、河北、山东三省建成中小型桥梁200座。对排涝、城乡物资交流和农业生产起到很大作用。为了发扬、充实这项新工艺,经搜集和整理群众在施工中(大部分是农村小型桥)有关经验体会,提供大家探讨。
Drilling and pouring concrete piles is a new technology that meets the requirements of more speed and better performance and is a major technological innovation. It is developing rapidly in the current construction of our country. In this way, the transport sector completed 3000 meters of road and bridge lengthways; and 200 small and medium sized bridges were built in Henan, Hebei and Shandong provinces for water conservancy construction. Drainage, urban and rural areas and the exchange of agricultural production play a big role. In order to carry forward and enrich this new craft, we are going to explore the experience gained through the collection and arrangement of the masses’ experience in construction (mostly small bridges in rural areas).
