一本《光荣册》辗转送到宝钢二十冶副总工程师张惠甸手中,他的软土地基拉锚支护技术荣获全国施工技术进步优秀项目奖,欣喜之余,思绪把他拉回到几年前……上海首家中日合资的五星级宾馆——太平洋大饭店开始招标兴建了。其中有一项技术难题:地基深大,土质松软。按传统旒工方法,开挖后为防止泥土流塌,应以层层叠叠的长钢管顶住贴附于四壁的钢板桩。可是这样一来,坑内构件纵、横交错,施工不便,况且80米长的一批钢管来源困难而且昂贵。显然,找到更合理更科学的新施工方案,是施工单位中标的重要条 A “Glory Book” was transferred to Zhang Huidian, deputy chief engineer of Baosteel 20 Metallurgical Co., Ltd. His soft soil foundation anchor support technology won the National Excellent Prize for Construction Technology Progress Award. He rejoiced, his thoughts pulled him back. A few years ago... Shanghai’s first Sino-Japanese joint-venture five-star hotel, the Pacific Hotel, was tendered for construction. One of the technical problems is that the foundation is deep and the soil is soft. According to the traditional method of construction, in order to prevent the collapse of mud after excavation, long steel tubes should be stacked against the steel sheet piles attached to the four walls. However, as a result, the internal components of the pit are staggered vertically and horizontally, which makes construction inconvenient. Moreover, the 80-meter-long batch of steel pipes is difficult and expensive to source. Obviously, finding a more reasonable and scientific new construction plan is an important part of the bid for the construction unit.
