Building foundation pile head waterproof structure and construction method thereof

DONG LEI

The invention belongs to the technical field of building waterproofing, and particularly relates to a building foundation pile head waterproof structure and a construction method thereof.The building foundation pile head waterproof structure comprises a foundation pile head, the lower portion of the foundation pile head is buried in a foundation soil layer, a concrete cushion layer is laid on the foundation soil layer, and a waterproof layer is laid on the concrete cushion layer. When the pile head settles and the waterproof layer is pulled downwards, the waterproof layer with a certain length can be automatically unfolded, the waterproof layer is prevented from being tightened and torn due to the fact that the downward pulling distance of the settled pile head is too large, the waterproof performance of the waterproof layer is guaranteed, and the waterproof layer can be automatically unfolded when the waterproof layer below the pile head is damaged due to aging, cracking and other problems. The damaged part of the waterproof layer can be automatically filled with waterproof concrete, gaps of the pile head are filled with the waterproof concrete, the waterproof capacity of the pile head is guaranteed, the contact area between the pile head and the concrete cushion layer is further increased, and the settling speed of the foundation pile head is slowed down.

本发明属于建筑防水技术领域，尤其是涉及一种建筑基础桩头防水结构及其施工方法，包括基础桩头，所述基础桩头的下部埋设于基础土层内，所述基础土层的上方铺设有混凝土垫层，所述混凝土垫层的上方铺设有防水层。本发明能够在桩头发生沉降向下拉扯防水层时，可以自动展开一定长度的防水层，避免了防水层被沉降的桩头下拉距离过大而紧绷撕裂，保证了防水层的防水性能，而且能够在桩头下方的防水层因为老化开裂等问题导致防水层破损时，可以自动向防水层的破损处填充防水混凝土，通过防水混凝土对桩头的缝隙进行填补，保证了桩头的防水能力，并且进一步增加了桩头和混凝土垫层之间的接触面积，延缓基础桩头的沉降速度。
