Construction method of high-energy-level dynamic compaction
The invention discloses a construction method of high-energy-level dynamic compaction. The construction method comprises the steps that step 1, the soil viscosity of a construction site is measured, and a reasonable rammer, reasonable hoisting equipment and a reasonable unhooking device are selected; step 2, compacting is performed for the first time in a point compaction mode with the main compaction energy level, compaction points are arranged in a square form, and the distance between the compaction points is 2-3.2 times of the diameter of the bottom surface of the rammer; step 3, the siteis leveled by a bulldozer, and a 1-3 m of gravel cushion is laid; compacting is performed for the second time in a point compaction mode with the main compaction energy level, compaction points are arranged in a quincuncial form, the distance between the compaction points is one second of the distance between the compaction points in step 2, and the compacting sequence is compacting row by row atthe angle of 45 degrees; and step 4, after a compaction pit is backfilled for the second time, compacting is performed for the third time in a full compaction mode with half of designed compacting energy of the main compaction energy level, and rammer marks are overlapped with one another by one fourth to one third. The construction method has the reinforcement effect capable of meeting the designrequirements, and zero supplementary compaction is basically achieved.
本发明公开了一种高能级强夯的施工方法，包括：步骤一、测量施工现场土质粘性，选取合理的夯锤、起重设备和脱钩装置；步骤二、采用主夯能级的点夯方式进行第一遍夯击，夯点形式为正方形布置，夯点间距离为夯锤底面直径的2～3.2倍；步骤三、用推土机整平场地，铺设1～3m的碎石垫层；采用主夯能级的点夯方式进行第二遍夯击，夯点形式为梅花形布置，夯点间距离为步骤二中夯点间距离的1/2，夯击顺序为45°角方向上一排一排夯；步骤四、回填第二遍夯坑后，采用设计主夯能级一半夯击能的满夯方式进行第三遍夯击，锤印彼此搭接1/4～1/3。本发明具有能够达到设计要求的加固效果，基本做到零补夯。
