Water stop pile construction technology
The invention provides a water stop pile construction process, which relates to the field of constructional engineering, and comprises the following steps: S1, positioning: cleaning a construction site, and determining a pile position; s2, drilling is conducted, specifically, drilling is conducted at the pile position through a drilling machine; s3, an injection pipe is lowered, slurry and gas test injection is conducted on the ground firstly, and after it is checked that all technological parameters meet the design requirements, the injection pipe is lowered to the design depth; s4, slurrying: mixing cement, fly ash, water and other materials according to a certain proportion to prepare slurry; s5, jet lifting is conducted, specifically, in the grouting process, the grouting pipe is slowly lifted, and grout is evenly distributed in the drill hole; s6, recharging is conducted, and static pressure filling grouting is conducted in the jet holes; s7, recording; s8, equipment cleaning: after construction is finished, grouting equipment is cleaned; the method has the advantages of simple construction process, light equipment, high mechanization degree and easiness in operation, and the construction efficiency is effectively improved; and the water stopping effect is good, underground water permeation can be effectively prevented in the construction process, the method is suitable for any soft soil layer, and the reinforcing range can be controlled.
本发明提供的一种止水桩施工工艺，涉及建筑工程领域，包括以下步骤：S1定位，清理施工现场，确定桩位；S2钻孔，使用钻机在桩位处钻孔；S3下喷射管，先在地面进行浆、气试喷，检查各项工艺参数符合设计要求后将喷射管下至设计深度；S4制浆，将水泥、粉煤灰、水等材料按一定比例混合，制备成浆液；S5喷射提升，在注浆过程中，缓慢提升注浆管，使浆液均匀分布在钻孔内；S6回灌，在喷射孔内进行静压充填灌浆；S7记录；S8清洗设备，施工结束后，清洗注浆设备；本发明具有施工工艺简单，设备轻便、机械化程度高，易于操作，有效提高施工效率；且止水效果好，在施工过程中可有效防止地下水渗透，适用于任何软弱土层，加固范围可控制的技术效果。
