Construction method for deep foundation pit in reclamation area
The invention relates to the field of deep foundation pit construction, in particular to a construction method for a deep foundation pit in a reclamation area. The construction method for the deep foundation pit in the reclamation area comprises the following steps: S10, excavating a first layer of earth in the foundation pit; S20, supporting the foundation pit; S30, excavating a second layer of earth in the foundation pit; S40, carrying out outward transportation of earthwork; S50, carrying out precipitation treatment; S60, pouring a cushion layer; S70, conducting structure construction; S80, backfilling the foundation pit; and S90, removing the support. The embodiment of the invention has the beneficial effects that after the first layer of earthwork in the foundation pit is excavated, the foundation pit is supported, then the second layer of earthwork is excavated in the foundation pit, the excavated earthwork is transported outwards, the foundation pit is subjected to dewatering treatment, then the cushion layer is poured, structural construction is carried out in the foundation pit, and finally the foundation pit is backfilled and the support is removed. Through the construction process, the use cost is reduced, the construction difficulty is reduced, and the construction safety and the construction quality are guaranteed.
本发明涉及深基坑施工领域，具体而言，涉及一种填海区深基坑施工方法。填海区深基坑施工方法包括如下步骤：S10，基坑内第一层土方开挖；S20，基坑支护；S30，基坑内第二层土方开挖；S40，土方外运；S50，降水处理；S60，浇注垫层；S70，结构施工；S80，基坑回填；S90，支护拔除。本发明实施例的有益效果是：先经过基坑内第一层土方开挖后，再进行基坑支护，之后在基坑内进行第二层土方开挖，将挖出的土方进行外运，对基坑进行降水处理，之后再浇注垫层，再基坑内进行结构施工，最后进行基坑回填和支护拔除。经过上述的施工过程，降低了使用成本，降低了施工难度，保证了施工的安全性和施工质量。
