Soft soil foundation layer precipitation construction structure and method
The invention relates to a soft soil foundation layer precipitation construction structure, and belongs to the technical field of building construction. The soft soil foundation layer precipitation construction structure comprises a well tube, an inner sleeve, a driving assembly, a closed tube, a borehole submerged pump, a precipitation tube and a switch valve. The invention further discloses a soft soil foundation layer precipitation construction method. The method includes the steps of firstly, forming a hole; secondly, disposing the inner sleeve at a deep well part of the well tube; thirdly, putting down the tube; fourthly, putting the borehole submerged pump into the deep well part of the well tube; fifthly, putting the closed tube and the driving assembly together into the deep well part; sixthly, driving the closed tube by the driving assembly to do outwards expanding movements; seventhly, before digging a foundation pit, starting the borehole submerged pump for precipitation; eighthly, digging the foundation pit, releasing the closed tube by the driving assembly after the foundation pit is dug at a depth where pressure reduction is needed, and performing precipitation through the borehole submerged pump; ninthly, intermittently driving the closed tube by the driving assembly to extrude the inner sleeve; and tenthly, ending the precipitation after the foundation pit is dug. The structure and method have the advantages that the number of tube wells is small, and construction is facilitated.
本申请涉及一种软土地基分层降水施工结构，属于建筑工程技术领域。其包括井管、内套管、驱动组件、封闭管、潜水深井泵、降水管和开关阀，还包括一种软土地基分层降水施工方法，其步骤为：1）、成孔；2）、把内套管安装在井管的深井部；3）、下管；4）、把潜水深井泵放入井管的深井部；5）、把封闭管和驱动组件一起放入深井部；6）、通过驱动组件驱动封闭管做外扩运动；7）、基坑开挖前，开启潜水深井泵进行降水；8）、进行基坑开挖，基坑开挖到需要降压的深度后，通过驱动组件放松封闭管，通过潜水深井泵进行降水；9）、通过驱动组件间歇驱动封闭管挤压内套管；10）、基坑开挖完毕，结束降水。本申请具有管井数量少而施工方便的优点。
