Deep foundation pit fat groove dewatering construction method
The deep foundation pit fat groove dewatering construction method comprises the following steps that S1, a horn mouth cement pipe is treated, specifically, round holes are formed in the periphery of the horn mouth cement pipe, first geotechnical cloth is used for winding the periphery of the horn mouth cement pipe 1, the round holes are wrapped, and a plurality of triangular plates and vertical rods are fixed in a horn mouth of the horn mouth cement pipe; s2, cleaning the bottom of the fertilizer tank: after the floor scaffold in the fertilizer tank is removed, cleaning the drainage ditch and the water collecting pit. The design is reasonable, through the arrangement of the water guide layer, crack water of all parts in the whole foundation pit range can be collected into the cement pipe and is matched with the multiple round holes in the horn-shaped cement pipe, crack water of different parts in rock is discharged, the overall underground water level can be effectively reduced, the horn-shaped cement pipe is high in strength, and the service life of the cement pipe is prolonged. The downward horn mouth is formed in the bottom of the horn mouth cement pipe, extrusion dislocation at a connector in the backfilling process can be effectively avoided, the connector quality is guaranteed, and the phenomenon that a pipe well is silted can be avoided.
本发明公开了一种深基坑肥槽降水施工方法，包括以下步骤：S1，喇叭口水泥管处理：将喇叭口水泥管四周打圆孔，并用第一土工布对喇叭口水泥管1的四周进行缠绕，将圆孔包裹，将多个三角形板及竖杆固定在喇叭口水泥管的喇叭口内；S2，肥槽底部清理：肥槽内落地脚手架拆除后，将排水沟和集水坑清理干净。本发明设计合理，通过导水层的设置，能够将整个基坑范围内各个部位的裂隙水汇集至水泥管内，与喇叭口水泥管上多个圆孔配合，将岩石中不同部位的裂隙水排出，可以有效降低整体地下水位，且喇叭口水泥管强度较高，喇叭口水泥管底部具有朝下的喇叭口，可以有效避免回填过程中接口处的挤压错位，保障接头质量，并能够避免发生管井淤死现象。
