Drilling ramming and expanding equipment for compaction pile and using method of drilling ramming and expanding equipment
The invention discloses a compaction pile drilling ramming and expanding device, and relates to the technical field of foundation construction, the compaction pile drilling ramming and expanding device comprises an operation platform, and the top of the operation platform is provided with a test assembly. An air pump is started, under the air suction effect of the air pump, a piston and a traction rope pull a magnetic block, a tension meter, a fixing block, a traction chain and a ramming and expanding assembly till an impact hammer is pulled to the highest position, at the moment, the air pump is stopped, and an electromagnetic valve is opened, so that air enters an exhaust pipe instantly, the impact hammer falls instantly, and first-time ramming of a compaction pile is completed; closing the electromagnetic valve, starting the air pump, enabling the air pump to suck the piston downwards again, observing the height of the iron ball sucked to the graduated scale by the magnetic block at the moment that the tension monitored by the tension meter changes suddenly, then repeating the operation, the height of the iron ball is different every time, and when the height of the iron ball is not changed, it is indicated that the compaction pile is compacted. The problem that the compactness cannot be known in time is solved.
本发明公开了一种挤密桩的钻孔夯扩设备，涉及地基施工技术领域，包括：操作平台，所述操作平台的顶部设置测试组件。本发明通过启动气泵，在气泵的吸气作用下，活塞和牵引绳拉动磁块、拉力计、固定块、牵引链和夯扩组件，直到冲击锤被拉到最高处，此时暂停气泵，通过打开电磁阀，从而使排气管瞬间进气，进而使冲击锤瞬间下落，完成对挤密桩的第一次夯实，关闭电磁阀，启动气泵，使得气泵再次将活塞向下吸，当拉力计监测出的拉力突然变化的瞬间，观察铁球被磁块吸到刻度尺的高度，然后再重复以上的操作，铁球的高度每次都是不同的，当铁球的高度不变时，便说明挤密桩已被夯实，解决了无法及时了解到密实性的问题。
