蛙式夯实机安全操作技术 | 2012-8-2 8:07:00

(1) 蛙式夯实机应适用于夯实灰土和素土的地基、地坪及场地平整,不得夯实坚硬或软硬不一的地面、冻土及混有砖石碎块的杂土。

(2) 作业前重点检查项目应符合下列要求:

a.除接零或接地外,应设置漏电保护器,电缆线接头绝缘良好。

b.夯土机械的负荷线应采用耐气候型的四芯橡皮护套铜芯软电缆。电缆线长短应不大于50m。

c.传动皮带松紧度合适,皮带轮与偏心块安装牢固。

d.转动部分有防护装置,并进行试运转,确认正常后,方可作业。

(3) 作业时夯实机扶手上的按钮开关和电动机的接线均应绝缘良好,在电动机的接线穿入手把的入口处,应套绝缘管。当发现有漏电现象时,应立即切断电源,进行检修。

(4) 夯实机作业时,应一人扶夯,一人传递电缆线:且必须戴绝缘手套和穿绝缘鞋。递线人员应跟随夯机后或两侧调顺电缆线,电缆线不得扭结或缠绕,且不得张拉过紧,应保持有3~4m的余量。

(5) 作业时,应防止电缆线被夯击。移动时,应将电缆线移至夯机后方,不得隔机抢扔电缆线,当转向倒线困难时,应停机调整。

(6) 作业时,手握扶手应保持机身平衡,不得用力向后压,并应随时调整行进方向。转弯时不得用力过猛,不得急转弯。

(7) 夯实填高土方时,应在边缘以内100~150mm夯实2~3遍后,再夯实边缘。

(8) 在较大基坑作业时,不得在斜坡上夯行,应避免造成夯头后折。

(9) 夯实房心土时,夯板应避开房心内地下构筑物、钢筋混凝土基桩、机座及地下管道等。

(10) 在建筑物内部作业时,夯板或偏心块不得打在墙壁上。

(11) 多机作业时,其平列间距不得小于5m,前后间距不得小于10m。

(12) 夯机前进方向和夯机四周1m范围内,不得站立非操作人员。

(13) 夯机连续作业时间不应过长,当电动机超过额定温升时,应停机降温。

(14) 夯机发生故障时,应先切断电源,然后排除故障。

(15) 作业后,应切断电源,卷好电缆线,清除夯机上的泥土,并妥善保管。
