Full-prefabricated pier-type portal frame inclined supporting pile structure system and construction method thereof
The invention relates to a fully-prefabricated pier-type portal frame inclined supporting pile structure system and a construction method thereof. The fully-prefabricated pier-type portal frame inclined supporting pile structure system is characterized in that a pier-type portal frame enclosure structure is formed by inserting prefabricated parts into cement-soil mixing piles, prefabricated inclined piles are pressed into a soil layer through an inclined pile pressing-in machine, and integral connection is formed with a second enclosing purlin in the front row of the pier-type portal enclosure structure to form a stable structure with soil retaining and overturning resistance, so that the breakthrough that the enclosure structure of a two-layer basement foundation pit has no horizontal inner support is realized. According to the fully-prefabricated pier-type portal frame inclined supporting pile structure system, the inclined prefabricated piles are integrally connected with the second enclosing purlin in the front row of the pier-type portal enclosure structure to form the stable structure with soil retaining and overturning resistance, so that no horizontal support construction exists in the pit, excavation construction is facilitated, the manufacturing cost is reduced, the construction period is shortened, the compression resistance of the inclined prefabricated piles and the friction force between the inclined prefabricated piles and the soil body are fully exerted, construction is simple, efficiency is high, steel can be recycled, and the cost is saved.
本发明涉及一种全预制墩式门架斜向支撑桩结构体系及其施工方法，全预制墩式门架斜向支撑桩结构体系是通过水泥土搅拌桩内插预制构件形成墩式门架围护结构，通过斜向压桩机将预制斜桩压入土层中，与墩式门架围护结构前排第二道围檩形成整体连接，形成具有挡土、抗倾覆的稳定结构，从而实现二层地下室基坑的围护结构无水平内支撑的突破。本发明采用斜向预制桩与墩式门架围护结构前排第二道围檩形成整体连接，形成具有挡土、抗倾覆的稳定结构，使坑内无水平支撑施工，方便挖土施工，降低造价，节约工期，充分发挥斜向预制桩的抗压性能及与土体的摩擦力，施工简单，效率高，钢材可循环利用，节约成本等优点。
