Then considering the friction forces on the well sides and well bottom, the permissible jacking force was calculated through the horizontal forces balance of the whole working well.
考虑了沉井底部和侧壁的摩阻力,由沉井整体水平向受力平衡计算允许顶力。
From the technology of reducing friction slurry and the relay jacks, the jacking force of long pipe jacking has been analyzed.
从触变泥浆减摩技术和中继接力技术两个方面对超长距离顶管施工中的顶推力进行了研究。
Theoretically, the jacking force can be enhanced arbitrarily, so the jacking distance can reach arbitrary length.
从理论上讲,千斤顶的顶力可以任意进步,从而也能达到任意长度的推顶间隔。
