Earth excavation construction method based on deep foundation pit
The invention relates to the field of foundation pit excavation construction, in particular to an earth excavation construction method based on a deep foundation pit, which comprises the following steps: S1, enclosure construction; s2, construction of a dewatering well and a pressurizing well; s3, earth excavation construction is conducted; s4, backfilling the dewatering well and the pressurizing well; a pressurizing air pipe is introduced into the pressurizing well and connected with a pressurizing air pump, and in the earth excavation process, the pressurizing air pump introduces air into the pressurizing well through the pressurizing air pipe, so that the air pressure in the pressurizing well is increased to a design value, and the air pressure in the pressurizing well is increased. The method has the effect of reducing waste of underground water resources caused by foundation pit dewatering construction.
本发明涉及一种基于深基坑的土方开挖施工方法，涉及基坑开挖施工的领域，其包括步骤：S1、围护施工；S2、降水井和加压井施工；S3、土方开挖施工；S4、降水井和加压井回填；加压井中通入加压气管，加压气管连接加压气泵，土方开挖的过程中，加压气泵通过加压气管向加压井内通入气体使得加压井内的气压升高到设计值，使得加压井内的气压升高。本申请具有减少基坑降水施工对地下水资源浪费的效果。
