Reinforcing structure of deep foundation pit close to existing building and implementation method of reinforcing structure
The invention belongs to the technical field of deep foundation pits, and discloses a reinforcing structure of a deep foundation pit close to an existing building and an implementation method of the reinforcing structure. The reinforcing structure close to the deep foundation pit of the existing building comprises a bottom water sealing layer and a foundation reinforcing layer, the bottom water sealing layer is located below the deep foundation pit and can seal the bottom of the deep foundation pit, and the bottom water sealing layer comprises a bottom sealing part and joint parts located on the two sides of the bottom sealing part; the joint part is used for reinforcing the joint between the bottoms of every two adjacent underground diaphragm walls, the foundation reinforcing layer is located at the bottom of the deep foundation pit and can reinforce the pit bottom of the deep foundation pit, the foundation reinforcing layer and the bottom water sealing layer are arranged in a spaced mode, and reinforcing piles are arranged at the joints between the foundation reinforcing layer and the underground diaphragm walls. By means of the reinforcing mode of the full bottom sealing of the pit bottom of the foundation pit, the drainage and pressure reduction operation quality is guaranteed, meanwhile, the influence on surrounding adjacent existing houses and environments in the construction process can be effectively reduced, and therefore the operation risk is reduced, and smooth engineering implementation is guaranteed.
本发明属于深基坑技术领域，公开了一种临近既有建筑物深基坑的加固结构及其实施方法。本发明中临近既有建筑物深基坑的加固结构包括底部封水层和地基加固层，底部封水层位于深基坑的下方，能够对深基坑的底部进行封底，底部封水层包括封底部和位于封底部两侧的接缝部，接缝部用于相邻两个地下连续墙的底部之间接缝处的加固，地基加固层位于深基坑的底部，能够对深基坑的坑底进行加固，地基加固层与底部封水层间隔设置，且地基加固层与地下连续墙之间接缝处设置有加固桩。本发明通过基坑坑底的满堂封底的加固方式，保证疏干降压作业质量的同时，能够有效减少施工过程中对周边临近既有房屋和环境的影响，以此降低作业风险，并保证工程顺利实施。
