Full-prefabricated K-shaped enclosure structure system and construction method thereof
The invention relates to a full-prefabricated K-shaped enclosure structure system and a construction method thereof. According to the full-prefabricated K-shaped enclosure structure system, a vertical enclosure structure is formed by inserting prefabricated parts into cement mixing piles, prefabricated inclined piles are pressed into a soil layer through an inclined pile pressing machine and integrally connected with the vertical enclosure structure, a K-shaped stable structure with the soil blocking and anti-overturning functions is formed by combining a first horizontal support and the vertical enclosure structure, and therefore the breakthrough that an enclosure structure of a two-layer basement foundation pit is not provided with a second horizontal inner support is achieved. According to the full-prefabricated K-shaped enclosure structure system and the construction method thereof, the prefabricated inclined piles are integrally connected with a second enclosing purlin of the vertical enclosure structure, the K-shaped stable structure with the soil blocking and anti-overturning functions is formed by combining the first horizontal support, the pit is not internally provided with the second horizontal support, excavation construction is convenient, the manufacturing cost is reduced, the construction period is shortened, the compressive property 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, efficiency is high, steel can be recycled, and the cost is reduced.
本发明涉及一种全预制K型围护结构体系及其施工方法，全预制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竖向围护结构，通过斜向压桩机将预制斜桩压入土层中，与竖向围护结构形成整体连接，结合第一道水平支撑与竖向围护结构形成具有挡土、抗倾覆的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竖向围护结构第二道围檩形成整体连接，结合第一道水平支撑，形成具有挡土、抗倾覆的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。
