High-underground-water-level fan foundation construction method
The invention relates to a high-underground-water-level fan foundation construction method. The high-underground-water-level fan foundation construction method comprises the following steps that 1) materials are selected, specifically, according to the characteristics of a site where a project is located and the characteristics of steel sheet piles, the 6m or 9m * 0.4m steel sheet piles are selected; 2) identification is conducted, specifically, a measuring person releases the pile position axis, and lime line identification is scattered; 3) the steel sheet piles are inserted and driven, specifically, the steel sheet piles are hoisted through a pile driver and are centralized in place, and the single piles are continuously inserted and driven one by one; 4) pit digging is conducted, specifically, after the steel sheet piles are inserted and driven, secondary paying-off is conducted, and mechanical pit digging is conducted after secondary paying-off is completed; 5) manual bottom cleaning is conducted, specifically, manual bottom cleaning is conducted on the remaining 20cm pit bottom which is not dug in the step 4); 6) well point dewatering is arranged, specifically, after the pit bottom is dug, annular well point dewatering is arranged at the position 1.0m away from the edge of a foundation pit, and the distance between every two well point dewatering pipes is 1.0m; and 7) after foundation pouring is completed, bearing platform corrosion prevention and grounding construction are conducted. The high-underground-water-level fan foundation construction method has the advantages that effective dewatering is achieved, backward flowing and collapse are prevented, and the construction efficiency is improved.
本发明涉及高地下水位风机基础施工方法，它包括以下步骤：步骤1）：选材，根据工程所在场地特点，以及钢板桩的特性，选用6m或9m*0.4m钢板桩；步骤2）：标识，由测量人员放出桩位轴线，撒白灰线标识；步骤3）：钢板桩插打，打桩机吊起钢板桩，扶正就位，单桩逐根连续插打；步骤4）：挖坑，钢板桩插打完，进行二次放线，二次放线完成后进行机械挖坑；步骤5）：人工清底，将步骤4）中剩余的20cm未挖的坑底进行人工清底；步骤6）：布置井点降水，上述坑底挖成后，在距离基坑边缘1.0m处布置环形井点降水，每根井点降水管间距1.0m；步骤7）：基础浇筑完毕后，进行承台防腐和接地施工；本发明具有有效降水、防止倒灌、防止塌方、提高施工效率的优点。
