Manual hole digging pile prefabricated protection wall and construction method thereof
The invention provides a manual hole digging pile prefabricated protection wall and a construction method thereof. The protection wall comprises at least three protection wall prefabricated sections which can be spliced to form a closed circular ring in a surrounding mode, wherein the arc length of the protection wall prefabricated sections is smaller than one half of the perimeter of the circular ring where the protection wall prefabricated sections are located, at least one protection wall prefabricated section is provided with a backfill opening, and the backfill openings are formed in the positions close to the tops of the protection wall prefabricated sections. According to the manual hole digging pile prefabricated protection wall and the construction method thereof, on-site splicing is carried out through the protection wall prefabricated sections prefabricated in advance, and the problems that the construction period is long, the cost is high, and the safety is difficult to guarantee due to traditional on-site pouring are effectively solved; the protection wall is prefabricated in advance, only soil needs to be dug in a hole, the protection wall is installed and fixed, continuous excavation can be carried out without waiting for the strength of concrete, and the hole digging efficiency is effectively improved; the protection wall is prefabricated in batches, the quality stability is guaranteed, and the labor and material cost is reduced to a certain extent; and the protection wall can be rapidly installed after excavation forming, the working efficiency of in-hole protection wall construction is effectively improved, the hole wall collapse risk is reduced, and the construction safety is guaranteed.
本发明提供一种人工挖孔桩预制护壁及其施工方法，该护壁包括可拼接围成封闭圆环的至少三个护壁预制段，护壁预制段的弧长小于护壁预制段所在圆环周长的二分之一，至少一个护壁预制段上开设有回填口，回填口设于靠近护壁预制段顶部位置处。本发明通过提前预制的护壁预制段进行现场拼接，有效避免了传统现场浇筑带来的施工周期长，成本高，安全性难以保障的问题；提前预制护壁，孔内只需挖土，安装和固定护壁，不用等混凝土上强度可连续开挖，有效提高了挖孔的效率；护壁的批量预制，质量稳定有保证，一定程度的降低了人工和材料成本；在开挖成型后可以迅速安装护壁，有效提高了孔内护壁施工的工作效率，减少孔壁坍塌风险，保证了施工的安全。
