Raft foundation construction method for pile foundation detection and prefabricated raft
The invention discloses a raft foundation construction method for pile foundation detection and a prefabricated raft. After pile foundation construction is completed, a static load test needs to be carried out on a constructed pile foundation, and the prefabricated raft is installed on a pile foundation detection site. Then, the static load test is conducted on the prefabricated raft, and the relation between a load and foundation deformation and a change rule of soil sinking along with time under the action of the load are obtained. After the static load test is completed, the prefabricated raft is recycled, and the prefabricated raft can be conveyed to a next pile foundation detection site. The prefabricated raft does not need to be chiseled away after the static load test is completed, can be repeatedly used, saves material cost and labor cost, saves the time of pouring around a pile foundation to form the raft in the early stage, and improves the construction efficiency.
本申请公开了一种用于桩基检测的筏板基础施工方法及预制筏板。在桩基施工完成后，需对已经施工完成的桩基进行静力载荷试验，通过在桩基检测场地上安装预制筏板。然后，在所述预制筏板上进行静力载荷试验，求得荷载与地基变形的关系，以及在荷载作用下土体下沉随时间的变化规律。在完成静力载荷试验回收所述预制筏板，并且可将预制筏板运送至下一个桩基检测场地。该预制筏板在完成静力载荷试验后不需要凿除，能够重复实用，节省了材料成本以及人工成本，并且节省了前期在桩基周围浇筑形成筏板的时间，提高了施工效率。
