Fully-prefabricated portal frame type K-shaped enclosure structure system and construction method thereof
The invention relates to a fully-prefabricated portal frame type K-shaped enclosure structure system and a construction method thereof. According to the fully-prefabricated portal frame type K-shaped enclosure structure system, a portal frame type vertical enclosure structure is formed by inserting prefabricated parts into cement-soil mixing piles, and prefabricated inclined piles are pressed into a soil layer through an inclined pile press; and the prefabricated inclined piles are integrally connected with the front row of the portal frame type vertical enclosure structure, and a first horizontal support and the portal frame type vertical enclosure structure are combined to form a soil-retaining and anti-overturning portal frame type K-shaped stable structure, so that the breakthrough that the enclosure structure of a two-layer basement foundation pit is not provided with a second horizontal inner support is achieved. According to the fully-prefabricated portal frame type K-shaped enclosure structure system and the construction method thereof, the prefabricated inclined piles and the portal frame type vertical enclosure structure are adopted to form the soil-retaining and anti-overturning portal frame type K-shaped stable structure, so that no second horizontal support exists in the pit, excavation construction is facilitated, the manufacturing cost is reduced, the construction period is shortened, the compression resistance of the prefabricated inclined piles and the friction force between the prefabricated inclined piles and a soil body are brought into full play, construction is easy, the efficiency is high, and the steel can be recycled. The cost is saved.
本发明涉及一种全预制门架式K型围护结构体系及其施工方法，全预制门架式K型围护结构体系是通过水泥土搅拌桩内插预制构件形成门架式竖向围护结构，通过斜向压桩机将预制斜桩压入土层中，与门架式竖向围护结构前排形成整体连接，结合第一道水平支撑与门架式竖向围护结构形成具有挡土、抗倾覆的门架式K型稳定结构，从而实现二层地下室基坑的围护结构无第二道水平内支撑的突破。本发明采用预制斜桩与门架式竖向围护结构形成具有挡土、抗倾覆的门架式K型稳定结构，使坑内无第二道水平支撑，方便挖土施工，降低造价，节约工期，充分发挥预制斜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。
