Combined plate cable foundation hole body backfill tamping device and method
The invention belongs to the technical field of combined plate cable and anchor cable backfill tamping instruments, and discloses a combined plate cable foundation hole body backfill tamping device and method. The combined plate cable foundation hole body backfill tamping method comprises the steps that combined plate cable foundation pile pit backfill is laid in a layered mode; the paving thickness of each layer, the ramming times of each layer and the height of each falling distance of a rammer are controlled according to the changing rule of the compactness of hole body backfill after ramming; and hammer falling should be kept stable, and ramming positions should be accurate. The tamping compaction of the backfill in the hole body can be realized, the defect that the tamping quality isnot easy to guarantee due to the fact that an existing flat-bottom rammer is easy to incline in the falling process can be overcome, and the tamping efficiency is improved. In addition, a through holeis formed in the middle, so that a combined plate cable main anchor can smoothly penetrate through the through hole, air waves can be emptied through an air hole, and the air waves generated in the rammer falling process are reduced. Layered ramming is conducted, and the situation that each layer of rammed earth reaches the designed compactness.
本发明属于联合板索锚索回填土夯实器械技术领域，公开了一种联合板索基础孔体回填土夯实装置及方法，所述联合板索基础孔体回填土夯实方法包括：联合板索基础桩坑回填土，采用分层铺筑；根据孔体回填土夯击后的压实度变化规律，控制每层铺筑厚度、每层的夯击次数和夯锤每次落距的高度；落锤应保持平稳，且夯位准确。本发明可实现孔体内回填的夯击密实，能够克服现有平底夯锤下落易倾斜夯偏夯实质量不易保证的缺点，提高了夯实效率。此外中间设置贯通孔不仅可以保证联合板索主锚顺利穿过，更有利于通过气孔将气浪排空，减少夯锤下落过程中产生的气浪。分层夯击，能够保证每层夯土达到设计的密实度。
