Rigidity pile composite foundation differential settlement control method
The invention discloses a rigidity pile composite foundation differential settlement control method. The rigidity pile composite foundation differential settlement control method comprises the following steps that detection is conducted, and a too long rigidity pile is subjected to short cutting; a transition material block is placed on the pile top of the rigidity pile; refilling of plain concrete is conducted on the pile top of the rigidity pile so that the transition material block can be fixed; and a raft is poured to the transition material block and the plain concrete. The flexible transition material block with a force transmitting function and the reinforced concrete raft are designed on the road section where differential settlement happens to a rigidity pile composite foundation,the bearing capacity requirement can be met under the situation that road surface settlement is little, the differential settlement can be balanced under the situation that road surface settlement islarge, the characteristic of rigidity and softness combination is achieved, pile and soil settlement can be collaboratively conducted, and the disease caused by differential settlement is weakened and even eliminated.
本发明公开了一种刚性桩复合地基差异沉降控制方法，包括以下步骤：检测并对过长的刚性桩进行截短；在所述刚性桩的桩顶放置过渡材料块；在所述刚性桩的桩顶回填素砼用以固定所述过渡材料块；在所述过渡材料块和所述素砼上浇筑筏板。通过在刚性桩复合地基出现差异沉降的路段设计柔韧且具备传力功能的过渡材料块和钢筋混凝土的筏板，既能在路面沉降较小的情况下满足承载力的要求，又能在路面沉降较大的情况下平衡差异沉降，具有刚柔兼备的特点，保证桩土沉降能协调进行，弱化甚至消除因差异沉降而导致的病害。
