The author has made three experiments to evaluate the effect of water glass sand vibrating-reelaimation.When the adhesive coating on the surfaoe of tde used sand grians is peeled off by the vibrating force and pass through the dust counter in the form of dust,the dust density of the reclaimation degree will be continuously displayed in the form of figures,In the experiment,size analysis is done with the image analysing device;Sodium oxide content is determined by the consuming amount of the improved standard acid.The analysis result suggests that it is effective to pretreat the used water glass sand first and then to reclaim it with dry-vibrating method,The author′s view is that,the screen analysis method of sand size analysis may be gradually replaced by image analysis method,and further research should be done on the titrimetry of deter- mining sodium oxide composition.

为了评价水玻璃砂用振动法再生的效果,作者进行了三种试验。当旧砂颗粒表面的粘结层受振动力作用剥落,并以粉尘的形式通过粉尘计,表示再生程度的粉尘浓度以数字的形式连续显示出来。在作者的实验中,粒度分析是由映象分析装置来进行的;氧化钠的含量是用改进的标准酸消耗量方法测定。分析的结果表明,水玻璃砂旧砂预处理后,再用干式振动法进行再生是有效的。作者认为,分析砂粒度的筛分法有可能逐步被映象分析法取代,而测定氧化钠成份的滴定法应做进一步的研究。

The process of devolatilization of large coal particles is experimen- tally investigated.In the experiment,coal particles with diameters of 5.26~ 16.33mm were,in batches,dropped into a small electrically heated sand bed which is fluidized by air.The sand size of the bed and the oxygen concentra- tion of fluidizing air were varied.Oxygen and carbon dioxide concentrations in the freeboard of the bed were measured.It is found that the oxygen concentration of fluidizing air has certain influence on coal devolatilization time,but the bed sand size has little effects on it.This indicates that the heat rediation is the prevailing mechanism of heat transfer between bed and coal particles in the stage of devolatilization.

在一个电加热的砂子流化床中,研究了当量粒径为5.26~16.33mm烟煤粒的脱挥发份过程.实验中追踪流化床自由空间 CO_2的浓度变化,测定了批量煤粒脱去挥发份的时间,采用了四种不同粒径的床料及三种不同的流化风氧浓度,研究了煤粒的加热及床中氧浓度对脱挥发份过程的影响.结果表明:床中氧浓度对煤粒脱挥发份的时间有重要影响,而床料粒径则几乎没有影响,这说明在脱挥发份阶段热辐射是床向煤粒传热的主要方式.

There are five methods for the installation of the sand compaction piles described in the paper. 1. Rotary drilling. A portable core rig is used to drill holes to the desired depth.

There are five methods for the installation of the sand compaction piles described in the paper. 1. Rotary drilling. A portable core rig is used to drill holes to the desired depth. After pulling the drilling tools, the sand is poured into the hole to be compacted. 2. Jetting—churning drilling. A jet nozzle in combination with the churning drilling is used fo drill holes to the desired depth. Then the sand is poured into the hole to be compacted or the pocketed sand is installed. 3. Static pressing with a whole—length casing. The casing with a shoe of pile at its bottom is pressed to the desired depth by a special press. The casing can be pulled out the hole after the pocketed saud is iustalled into it. 4. Casing driven by pile hammer or vibrator. The casing with a shoe of pile at soil bed is driven down to the designed depth by a pile driver with a hammer or vibrator. Then the sand is poured into the casing from the top using a hopper. The casing is withdrawn while hammering or vibrating in order to compact the sand. 5. Franki rig. The casing is first filled with sand to a sufficient height. The sand at the bottom of the casing is then gently compacted to form a plug using an internal hammer. The casing is driven down to the designed depth by graduallg increasing the drop height. Additional sand is poured from the top hopper and rammed down through the casing during it extracted. The parameters in governing quality for the installation of the sand compaction piles include the pile depth, pile position, sand size, silt content of the sand and the volume of the added sand. When the pocketed sand is used, the quality and size of the pocket must be controlled strictly.

本文叙述砂桩施工的五种方法,1、回转钻进法,使用轻便岩心钻机钻孔,提钻后向孔内灌砂密实。2、水力冲击法,利用水力喷射和冲击相结合成孔,孔内灌砂密实或放入袋装砂。3、全套管静正法,由专用砂桩机把底端带桩靴的套管压到设计深度,管内放入袋装砂,然后拔管。4、锤击或振动沉管法,用锤击或振动沉桩机把底端带柱靴的柱管沉入土层至设计深度,然后从桩管上端的加料斗灌砂,边拔管边锤击或振动密实砂桩。5、法兰基钴机法,先在桩管中灌入足够高度的砂,后用内落锤密实砂子形成砂塞,把桩管沉入设计深度,在拔管中从加料斗加入砂量。砂桩施工质量的控制参数包括桩的深度、桩的定位、砂子粒度、含泥量和灌砂量。在采用袋装砂时,必须严格控制袋料质量和加工规格。
