Prefabricated rectangular anti-slide pile retaining wall and construction method thereof
The invention relates to a prefabricated rectangular anti-sliding pile retaining wall and a construction method thereof. The prefabricated rectangular anti-sliding pile retaining wall is formed by connecting a plurality of prefabricated rectangular sub retaining walls up and down, connection between adjacent sub retaining walls is realized through direct embedment of concave-convex connecting openings, a wedge-shaped structure which is favorable for sinking of the retaining walls is arranged at the lower end of the first section of the sub retaining wall located at the bottommost layer, and the outer part of the wedge-shaped structure is wrapped with a wear-resistant layer. The retaining wall is prefabricated in advance and spliced on site, and the construction speed is fast. During the construction, retaining wall splicing is carried out at a hole opening while excavating is carried out, excavating downwards is carried out section by section, the weight of the retaining wall or groundmachinery are used to assist in sinking, so that the operation is not only efficient, but also safer and more guaranteed, the risk of hole collapse during construction is not needed to be worried about, in addition, the construction of locking wellheads can be omitted, and the cost of building the locking wellheads and other costs can be saved accordingly. In summary, the prefabricated rectangular anti-sliding pile retaining wall is reliable in structure and simple in construction, the requirements of economic benefits are met, and the requirements of an emergency rescue project on time and quality safety are met.
本发明涉及一种预制装配式矩形抗滑桩护壁及其施工方法，该护壁由多节预制的矩形子护壁上下连接而成，相邻子护壁之间通过凹凸接口直接嵌合实现连接，位于最底层的首节子护壁的下端设有一段有利于护壁下沉的楔形结构，所述楔形结构的外部包裹有耐磨层。本发明护壁提前预制、现场拼接，施工速度快。施工时，边开挖边在孔口进行护壁的拼接，一段一段往下开挖，利用护壁自重或地面机械协助下沉，这样作业不仅高效，而且安全更有保证，施工的时候不用担心塌孔的危险，此外还能够省去锁口的建造，相应也就节约了建造锁口的费用等成本。综上，本发明结构可靠，施工简单，不仅仅满足经济效益要求，也可以满足抢险的工程对于时间和质量安全的要求。
