Cast-in-situ bored pile concrete surface elevation device and method
The invention discloses a cast-in-situ bored pile concrete surface elevation device and method. The cast-in-situ bored pile concrete surface elevation device comprises a pile casing installed in a deep hole, an automatic rotation device, a measuring rope and a hanging ball, wherein the automatic rotation device, the measuring rope and the hanging ball are installed on the pile casing; the pile casing is located at the top of the deep hole, and part of the pile casing stretches out of the deep hole; the depth of the deep hole is not smaller than 10m; the measuring rope is provided with a plurality of scales; one end of the measuring rope is connected with the automatic rotation device, and the other end of the measuring rope is connected with the hanging ball; in the lifting process of the hanging ball in the deep hole, the gravity of the hanging ball is G, and the automatic rotation device generates tension F to the hanging ball all the time through the measuring rope; and the tension F is smaller than G all the time, so that the measuring rope is in a tensioned state all the time, and part of the hanging ball is located on a mud layer, part of the hanging ball is located on a concrete layer, and the hanging ball can ascend along with ascending of the concrete layer. According to the technical scheme, the cast-in-situ concrete surface elevation can be rapidly and accurately measured in construction, and operation is easy.
本发明公开了一种钻孔灌注桩混凝土面标高装置和方法，包括安装在深孔内的护筒，以及安装在护筒上的自动回转装置、测绳和吊球，所述护筒位于深孔的顶部并且所述护筒部分伸出深孔外；所述深孔的深度不低于10m；所述测绳上设有若干刻度，所述测绳的一端与自动回转装置相连,所述测绳的另一端与吊球相连；吊球在深孔内的升降过程中，所述吊球的重力为G，所述自动回转装置通过测绳始终对吊球产生拉力F拉；所述F拉始终小于G；从而使得所述测绳始终处于绷直状态，以及使得所述吊球部分位于泥浆层并且部分位于混凝土层并能够随混凝土层的上升而上升；本技术方案在施工中能够快速、准确测量出灌注混凝土面标高，操作简单。
