Engineering foundation dynamic compaction construction method
The invention relates to the technical field of engineering foundations, and particularly discloses a dynamic compaction construction method for an engineering foundation. The method comprises the steps that firstly, the ground of a construction area is cleaned and leveled; step 2, marking the position of a first tamping point according to a construction drawing, and numbering each tamping point; thirdly, a plurality of drainage pipes are laid in a non-ramming-point area of the construction area at intervals, the upper portions of the drainage pipes are leveled, and the elevation of the construction area is measured; fourthly, the crane and the high tower type fog gun machine are arranged at the corresponding positions of a ramming point, and the top elevation of a rammer is measured; 5, the high tower type fog gun machine is started, the rammer is lifted to the preset height, an unhooking device is started, after the rammer is unhooked and freely falls, a lifting hook is put down, and the height of the top of the rammer is measured; sixthly, the seventh step is repeated till the ramming frequency and the control standard of the ramming point meet the requirements; the problem that in the prior art, the dynamic compaction quality can be reduced when water mist is sprayed to a compaction point is solved.
本发明涉及工程地基技术领域，具体公开了一种工程地基强夯施工方法；步骤一、清理施工区域的地面并进行平整；步骤二、按照施工图纸标出第一遍夯点位置，并对每个夯点进行编号；步骤三、在施工区域非夯点区域间隔铺设多个排水管，并对排水管上方进行平整，测量施工区域的高程；步骤四、起重机和高塔式雾炮机设置在夯点对应位置处，测量夯锤顶高程；步骤五、开启高塔式雾炮机，将夯锤起吊到预定高度，开启脱钩装置，待夯锤脱钩自由下落后，放下吊钩，测量锤顶高程；步骤六、重复步骤七，直至夯点的夯击次数和控制标准符合要求；本发明解决了现有技术中夯点喷洒水雾会降低强夯质量的问题。
