Foundation pit enclosing pile suitable for space limitation condition and construction method thereof
The invention is applicable to a foundation pit enclosing pile suitable for a space limitation condition and a construction method thereof. The enclosing pile belongs to a reinforced concrete pile. Full-length bars are vertically arranged inside the side, close to an underground building, of the enclosing pile, and the portion, close to the other sides of the underground building, above the bottomof a foundation pit is not locally provided with bars to form a plain concrete part chiseled away during the later period. According to the foundation pit enclosing pile structure related in the invention, the plain concrete part in the enclosing pile structure is constructed in a reasonable and flexible rib arrangement mode; through the plain concrete part chiseled away from a pile body during the laser period, the cross sectional area and the volume of the pile body of the enclosing pile structure are reduced, and the structure construction space inside the enclosing pile is expanded relatively. A larger newly constructed structure construction space is reserved as far as possible under the condition of a limited space region. The bearing capacity of the enclosing pile and the safety ofan enclosure system are guaranteed to the maximum extent, the influence on an existing structure is reduced to the maximum extent, and the space regions is utilized to the maximum extent.
本发明涉及适用于空间受限条件下的基坑围护桩及其施工方法，所述围护桩为钢筋混凝土桩，其靠近既有地下建筑物一侧的内部竖向通长配筋，靠近另一侧基坑底部以上的部分局部不配筋，形成后期凿除素混凝土部分。本发明涉及的基坑围护桩结构，通过合理灵活的配筋方式构建了围护桩结构中的素混凝土部分，通过后期凿除桩体的素混凝土部分，缩小围护桩结构的横截面积和桩体体积，从而相对扩大了围护桩内侧的结构实施空间，在空间区域受限的情况下尽可能的预留出更大的新建结构实施空间，不仅最大限度的保障了围护桩承载力和围护体系安全，最大限度的减少对既有结构影响，也最大限度的利用了空间区域。
