强夯法施工,应按下列步骤进行:
The construction by dynamic compaction method shall be carried out according to the following steps:
1、清理并平整施工场地;
1. Clean and level the construction site;
2、标出第一遍夯点位置,并测量场地高程;
2. Mark the position of the first tamping point and measure the site elevation;
3、起重机就位,夯锤置于夯点位置;
3. The crane is in place and the rammer is placed at the ramming point;
4、测量夯前锤顶高程;
4. Measure the hammer top elevation before tamping;
5、将夯锤起吊到预定高度,开启脱钩装置,夯锤脱钩自由下落,放下吊钩,测量锤顶高程;若发现因坑底倾斜而造成夯锤歪斜时,应及时将坑底整平;
5. Lift the rammer to the predetermined height, open the decoupling
device, the rammer will fall freely, put down the hook and measure the
top elevation of the hammer; If the rammer is found to be skewed due to
the inclination of the pit bottom, the pit bottom shall be leveled in
time;
6、重复步骤5,按设计规定的夯击次数及控制标准,完成一个夯点的夯击;当夯坑过深,出现提锤困难,但无明显隆起,而尚未达到控制标准时,宜将夯坑回填至与坑顶齐平后,继续夯击;
6. Repeat step 5 to complete the tamping of one tamping point according
to the tamping times and control standards specified in the design; When
the tamping pit is too deep, it is difficult to lift the hammer, but
there is no obvious uplift, and the control standard has not been
reached, it is advisable to backfill the tamping pit until it is flush
with the pit top, and then continue tamping;
