摘要:
为研究稻秸秆绳的排水能力及稻秸秆绳排水体用于真空负压加固疏浚淤泥的可行性,研制秸秆通水量测试装置,采用室内真空固结模型试验,并开展秸秆排水体通水能力测试。试验结果表明:稻秸秆排水体的排水能力能够达到传统塑料排水板的排水能力,但受稻秸秆排水体编织方式、所受负压大小及降解时间等因素影响,随真空负压的减小而增加,随降解时间的增加而减小。疏浚淤泥真空负压模型试验结果显示,以稻秸秆排水体为竖向排水体真空负压处理疏浚淤泥时,泥面沉降及含水率等处理效果接近塑料排水板,因此,以秸秆绳排水体替代塑料排水板是可行的。
Abstract:
In order to study the drainage capacity of rice straw rope and the feasibility of using rice straw rope drainage body for vacuum negative pressure reinforcement of dredged silt, a straw water flow capacity test device was developed. The indoor vacuum consolidation model test was used to test the water drainage capacity of straw drainage body. The results showed that the drainage capacity of rice straw drainage water body could reach that of the traditional plastic drainage board, but it increased with the decrease of vacuum negative pressure and the increase of degradation time due to the braid mode, negative pressure and degradation time of straw drainage water body. The results of the dredged silt vacuum negative pressure model test showed that when the dredged silt was treated with straw drainage water body as vertical drainage water body vacuum negative pressure, the treatment effect of mud surface settlement and moisture content was close to that of plastic drainage board. Therefore, it's feasible to replace the plastic drainage board with straw rope drainage water body.
