一、前言自中央批准陆水蒲圻枢纽为三峡试验坝后,去年7月份起就在长江水利科学研究院积极展开了室内试验研究,并已基本上获得成功。在这个基础上,从去年12月初起又在陆水工地进行了较大规模的混凝土预制块接缝试验,由于工地党委的正确领导,长办领导的亲切关怀和指示,苏联专家的深入现场指导,各民团的大力支持,各单位的密切配合,加上试验人员的积极努力,刻苦钻研,经过半年来的摸索和实践,克服了不少困难。通过爆破、剪切、压水试验,证明混凝土预制块表面经过刷毛处理,无论采用浆砌或者灌浆的胶结方法,只要严格控制施工操作质量,均可胶结成为整体。现将初步成果论述于后,敬希读者批评指正。 I. INTRODUCTION Since the Central Government approved the Lu Shui Pu Yao Hub for the Three Gorges Experimental Dam, the pilot study on the Yangtze River Hydraulic Research Institute has been actively conducted since July last year and has basically achieved success. On this basis, from the beginning of December last year, a large-scale trial of concrete prefabricated joints was carried out at Lushui site. Due to the correct leadership of construction party committees and the cordial care and instructions of the leaders of long offices and the in-depth guidance of Soviet experts The vigorous support of various militia groups and the close cooperation of various units, together with the active efforts of the trial personnel, make painstaking efforts. After over six months of exploration and practice, many difficulties were overcome. Through blasting, shearing and water pressure test, it is proved that the surface of concrete prefabricated block is treated with bristles. No matter the method of cementing by grouting or grouting, as long as the quality of construction operation is strictly controlled, it can be cemented into a whole. Now the initial results discussed in the post, King hope readers criticism.
