为了开发利用长江淤泥资源,改革长期以来用粘土制砖的传统,以节约耕地,由苏州市科委、体改办牵头,组织有关单位在常熟开展了利用长江淤泥作制砖原料技术的研究及半工业性试验。研究工作的目的有三个:一是研究长江淤泥能否作为制砖原料,淤泥储量及分布。二是研究利用长江淤泥制砖的工艺流程、设备选型和工艺参数的确定。三是开展技术经济分析。有关单位在半年多的时间里开展了如下工作:1、对长江淤泥进行资源勘察,目的是摸清淤泥储量及其分布,并为实验室对淤泥作理化分析提供土样。长江常熟段岸线全长37.5公里,对福山农场芦福沙工区以东、望虞河口至耿泾塘以东、浒浦镇、金泾塘口东、白茆潮位站以西5个不同地区进行了钻探取样,共钻孔131个,钻探深度为4米,每米深取样1只,共取土样524只。这次钻探范围长3公里。纵深500米.钻探面积1.5平方公里。经过探察和计算看到,长江常熟河段淤泥储量丰富,其面积约为2500万平方米(含部分落潮时未露出水的滩地),按深度4米
In order to develop and utilize the resources of the Yangtze River silt, reforming the tradition of clay brick making for a long time to save arable land, the Suzhou Science and Technology Commission and the Department of Economic Restructuring have taken the lead in organizing the research and development of Changshu sludge as a raw material for brick making technology in Changshu. Semi-industrial test. The purpose of the research work is threefold: First, it is to study whether the Yangtze River silt can be used as raw bricks, sludge reserves and distribution. The second is to study the process flow, equipment selection and determination of process parameters for making bricks from the Yangtze River silt. The third is to carry out technical and economic analysis. The relevant units carried out the following tasks for more than six months: 1. The purpose of resource surveying the Yangtze River silt is to find out the silt reserves and their distribution, and to provide soil samples for laboratory physical and chemical analysis of silt. The Changshu section of the Changjiang River is 37.5 kilometers long, and it is located east of the Fufu sand-worked area of Fushan Farm, east of Wangmuhe Estuary to the east of Qiantang, Zhangpu Town, east of Jinyutangkou, and 5 areas west of Baiji Tide Station. Drilling sampling, a total of 131 drilling, drilling depth of 4 meters, 1 deep sampling per meter, a total of 524 soil samples. The drilling range is 3 kilometers long. 500 meters deep, drilling area of 1.5 square kilometers. After exploration and calculation, it was found that the Changshu section of the Changjiang River was rich in silt reserves, with an area of about 25 million square meters (including some beaches where water was not exposed during the ebb tide), and the depth was 4 meters.
