强夯夯锤在土中形成强大的冲击应力(可高达2/8000~2000mkn)从而压缩土体, 形成夯坑并提高地基的强度,降低压缩性等。5吨,---达到93m/min,内藏式的常闭制动器能够夯锤可靠的制动。
Strong impact stress (up to 2 / 8000 ~ 2000mkn) is formed in soil by dynamic compaction hammer, which can compress soil, form compaction pit, improve the strength of foundation and reduce compressibility. 5 tons, -- up to 93m / min, the built-in normally closed brake can brake the rammer reliably.
夯锤的冲击速度显著影响冲击应力从而影响强夯的加固效果。履带式吊车提升夯锤时,吊车桁架式臂杆悬挂钢丝绳(背绳)在夯锤重力与提升加速度的作用下,产生较大的拉力,钢丝绳产生延伸(被拉长),夯锤提升到额定高度时,夯锤在自动脱钩器的作用下脱钩,吊车一瞬间卸去载荷,吊车臂杆由于钢丝绳内应力的作用。
 
The impact velocity of rammer significantly affects the impact stress, thus affecting the reinforcement effect of dynamic compaction. When the crawler crane lifts the rammer, the steel wire rope (back rope) suspended on the truss boom of the crane will produce a large tensile force under the action of the gravity and lifting acceleration of the rammer, and the steel wire rope will extend (be elongated). When the rammer is lifted to the rated height, the rammer will decouple under the action of the automatic decoupler, and the crane will unload the load in an instant.
强夯机,反复向后,向前大幅度的摆动,导致吊车臂杆和有关机件受到冲击,轻则使吊车有关机件提前损坏,重则臂杆向后倾翻、折杆、造成起重臂后翻事故。所以说,突然卸载对于强夯机是正常工况,这一作业方式也是区别于一般起重设备明显的特征。
The heavy tamping machine swings backward and forward repeatedly, causing the crane boom and related parts to be impacted. In light, the crane related parts will be damaged in advance. In heavy cases, the boom will tip backward, and the boom will be folded, causing the crane boom to turn backward. Therefore, it is obviously different from the normal operation mode of dynamic compaction equipment.
强夯机起升载荷  从一定程度上来说,强夯机每一循环的起升载荷都是变化的, 强夯作业中的起升载荷除夯锤本身的质量外,还有锤顶上覆土质量、夯锤从夯坑提起初始时真空吸附力和土壤环向压力、摩擦阻力等。
To a certain extent, the lifting load of the dynamic compaction machine changes in each cycle. In addition to the mass of the hammer itself, the lifting load in the dynamic compaction operation also includes the mass of the soil on the top of the hammer, the vacuum adsorption force at the beginning of lifting the hammer from the tamping pit, the circumferential pressure of the soil and the friction resistance.
液压履带式强夯机一、强夯施工应用范围广:不带龙门架装置时,夯击能达到400吨米,能够满足大多数强夯施工的要求。特别是含水量较高的粘性土场地上,夯坑较深时提锤荷载远远超过夯锤的自重。为提高生产效率,起升机构常常是满载工作。
Hydraulic crawler dynamic compaction machine 1. Wide application range of dynamic compaction: without gantry device, the compaction can reach 400 tons per meter, which can meet the requirements of most dynamic compaction construction. Especially in the clay field with high water content, when the tamping pit is deep, the lifting load is far more than the weight of the tamping hammer. In order to improve the production efficiency, the lifting mechanism is often full load work.
