Water-rich deep foundation pit retaining pile notch excavation and support construction technology
The invention belongs to the technical field of retaining pile notch support, and particularly relates to a water-rich deep foundation pit retaining pile notch excavation and support construction technology. The technical problems in the background technology is solved. Channel steel and bamboo plywood are used as a soil retaining plate layered supporting and retaining soil body, grass curtains are further arranged on the bamboo plywood side, the channel steel is anchored between adjacent retaining piles on two sides, then mesh hanging and anchor spraying are carried out, and layered reinforcement is carried out with excavation depth until a foundation. The construction technology solves the technical problem that a retaining pile structure can not be closed due to the fact that the numberof underground pipelines on a main urban road is large and cannot realize relocation, or the cost is high and the time of relocation is long, the influence of urban underground pipelines on urban subway construction is reduced, the time of relocation is shortened and cost is saved, the construction period is shortened, favorable conditions are provided for subsequent construction, the construction at retaining pile notches can be carried out in parallel with the net hanging and anchor spraying around a deep foundation pit, the safe and orderly construction can be ensured, the construction efficiency is improved, the operation is simple, and the construction is safe.
本发明属于围护桩缺口支护技术领域，具体为一种富水深基坑围护桩缺口开挖支护施工工艺，解决了背景技术中的技术问题，其利用槽钢加竹胶板作为挡土板分层支挡土体，竹胶板侧还设有草帘，将槽钢锚固于两侧相邻的围护桩之间，之后挂网喷锚，随开挖深度分层加固直至基底。该施工工艺解决了城市主干道上由于地下管线众多无法迁改，或迁改费用较高、迁改时间较长而导致围护桩结构不能闭合的技术难题，减少了城市地下管线对城市地铁施工的影响，节约迁改时间及费用，缩短了施工工期，为后续施工提供了有利条件，围护桩缺口处施工可以与深基坑周边挂网喷锚平行作业，能保证安全有序的施工，提高了施工功效，操作简单，施工安全。
