夯坑周围地面不应发生过大隆起;
B. The ground around the ramming pit should not be heavily raised.
C.不因夯坑过深而发生起锤困难
C. Hammering difficulty does not occur due to too deep ramming pit
总之,各夯击点的夯击数,应使土体竖向压缩最大,而侧向位移最小为原则,一般为4~10击2)夯击遍数夯击遍数应根据地基土的性质和平均夯击能确定。可采用点夯2~3遍对于渗透性较差的细颗粒土,必要时夯击遍数可适当增加。最后冉以低能量淸夯2遍,满夯可流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机采用轻锤或低落距锤多次夯击,锤印彼此搭接。
In a word, the tamping number of each tamping point should maximize the vertical compression of the soil, and the minimum lateral displacement is the principle. Generally, the tamping number of times should be determined according to the nature of the foundation soil and the average tamping energy. Point tamping 2-3 times can be used for fine-grained soils with poor permeability. If necessary, the number of tamping times can be increased appropriately. Lastly, tamping with low energy twice, full tamping can be tampered with light hammer or low drop distance hammer for many times, and hammer prints overlap with each other
