大宽幅大厚度摊铺机应用探讨

针对传统摊铺机存在并机分层摊铺接缝处结合不紧密、半埋螺旋易造成离析、摊铺效率相对偏低等问题，从大宽幅摊铺的研究现状、主要工作参数的确定、防离析技术、机械的合理选配、效益比较、常见故障分析等方面探讨大宽幅、大厚度摊铺机的设计理念以及抗离析机理，针对各种离析提出设备的改进方法，促进大宽幅摊铺机的应用推广。

Discussion on Application of Pavers with Wide Width and Large Thickness

Due to the disadvantages of traditional pavers such as loose combination at paving joint, seg- regation lead by half-buried spiral and low paving efficiency, the application of pavers with wide width and large thickness is discussed in this paper. The research statuses, process parameters, avoiding segregate design, machine matching method, benefit comparison and common fault analysis are investigated to discuss the design idea and anti-segregate mechanism. The improved method of avoiding segregate is proposed to promote the application of pavers with wide with.
