Mounting method of prefabricated cushion cap

CHEN XIANGYANG

The invention relates to the technical field of cushion cap construction, in particular to a mounting method of a prefabricated cushion cap. The mounting method of the prefabricated cushion cap comprises the following steps that firstly, the prefabricated cushion cap is processed, and pile foundation reserved holes penetrating through the prefabricated cushion cap are formed in the prefabricated cushion cap; secondly, a cushion cap foundation is excavated, and the prefabricated cushion cap is positioned and mounted in the cushion cap foundation; thirdly, the prefabricated cushion cap is used as the working platform to complete the pile foundation construction along the pile foundation reserved holes; and fourthly, concrete is poured into the pile foundation reserved holes to complete the construction. By means of the mounting method, first mounting of the prefabricated cushion cap and then completing of the construction with the pile foundation reserved holes formed in the prefabricated cushion cap as the foundation are adopted, so that the cushion cap foundation adapts to the position error of the pile foundation construction, during the construction of the pile foundation, the prefabricated cushion cap is used as the working platform for the pile foundation construction, additional working platforms for the pile foundation construction are not needed, accordingly, the processis simplified, and the manufacturing costs are reduced.

本发明涉及承台施工技术领域，尤其是涉及一种预制承台安装方法。预制承台安装方法包括以下步骤：首先，加工预制承台，并在预制承台上开设贯穿预制承台的桩基预留孔；下一步，开挖承台基础，并将预制承台定位安装于承台基础内；下一步，以预制承台为工作平台，沿桩基预留孔完成桩基础施工；下一步，向桩基预留孔内浇筑混凝土，完成施工。本申请采用先安装预制承台，然后以预制承台上开设的桩基预留孔为基础完成桩基础的施工，从而使承台基础适应桩基础施工的位置误差；且在对桩基础施工时，以预制承台为桩基础施工的工作平台，不需要额外的桩基础施工的工作平台，从而简化工序、降低造价。
