【技术实现步骤摘要】
灌注桩孔底泥浆取样装置
本技术涉及建筑监理工具领域,更具体地说,它涉及一种灌注桩孔底泥浆取样装置。
技术介绍
灌注桩是指在施工现场的指定桩位上利用机械钻孔等方法形成桩孔,并在桩孔内放置钢丝笼、灌注混凝土后形成的桩。在桩孔形成后,根据《建筑桩基技术规范》JGJ94-2008规定:灌注混凝土前,孔底500mm以内的泥浆的相对密度应小于1.25,含砂率不得大于8%;黏度不得大于28s,因此,需要对灌注桩孔的孔底的泥浆进行抽样。目前,申请号为CN200910070411.7的中国专利公开了一种钻孔灌注桩孔底泥浆取样器,它包括底座、限位柱、导向杆、取样桶、提耳、导向圈、提环、密封圈、密封盖,使用时,将提升测绳一端与两个提环一端系住或用一段测绳系住两个提耳后再与提升测绳一端拴接,将取样器画满放进灌注桩孔底中,取样器到达孔底后,再适当施放测绳,其取样桶可继续下沉与密封盖分离即密封盖打开,泥浆进入取样桶,完成取样;将取样器从灌注桩中取出并静置一平台上,卸掉密封盖上的螺母,将密封盖移开即可将泥浆比重计放入取样桶进行测量或将取样桶由导向柱上抽出,将筒内泥浆倒入泥浆比重秤、漏斗粘度计、含砂量测定仪等进行比重、粘度、含砂率测量。这种钻孔灌注桩孔底泥浆取样器虽然原理简单,但取样后需要将密封盖的螺母取下才能对泥浆样品进行测量,再次使用时需要将密封盖重新固定才能使用,因此,这造成了一定程度上的使用不便,这种钻孔灌注桩孔底泥浆取样器具有改进空间。
