Special-shaped guide combined hammer for dynamic compaction
The special-shaped guide combined hammer comprises a basic rammer and a guide rammer, the basic rammer is in a convex shape, the bottom of the basic rammer is a cylindrical hammer body, a vertically-extending hammer neck is integrally arranged in the middle of the top end of the hammer body of the basic rammer, and a plurality of vertically-through exhaust holes are formed in the portion, on the outer side of the hammer neck, of the hammer body of the basic rammer according to an annular array; the hammer neck is cylindrical, the axis of the hammer neck and the axis of the hammer body are collinear, the center position of the top of the hammer neck is in threaded connection with a mushroom head hoisting screw which is coaxially arranged with the hammer neck, and the bottom end of the mushroom head hoisting screw penetrates through the hammer neck and extends to a certain depth in the hammer body; the top end of the base rammer body is fixedly connected to the center of the bottom end of the base rammer body, the axis of the base rammer body is collinear with the axis of the rammer body, and the cross section size of the base rammer body is smaller than that of the rammer body and larger than that of the rammer neck. The displacement depth can be greatly increased, positioning is accurate, the situation that a construction hammer body absorbs and tilts is not likely to happen, and the purposes of quality improvement and efficiency improvement are achieved.
本发明公开了一种强夯用异形引导组合锤，包括基础夯锤和引导夯锤，基础夯锤呈凸字形，其底部为圆柱状的锤体，其锤体顶端中部一体设置有竖向延伸的锤颈，且其锤颈外侧的锤体上按环形阵列开设有若干个竖向贯通的排气孔，锤颈呈圆柱状，且其轴心与锤体轴心共线，锤颈顶部中心位置螺纹连接有与其同轴设置的蘑菇头吊装螺杆，且蘑菇头吊装螺杆的底端贯穿锤颈并延伸至锤体内一定深度处，引导夯锤呈圆柱状，其顶端固定连接在基础夯锤锤体的底端中心位置，且其轴心与锤体轴心共线，其横截面尺寸小于锤体的横截面尺寸并大于锤颈的横截面尺寸。本发明可大幅增加置换深度，而且定位准确，不容易造成施工锤体吸锤及歪锤的情况，达到了提质增效的目的。
