袖阀管注浆加固强夯填土地基

Sleeve Valve Pipe Grouting Reinforcing Compaction Backfill Foundation

经强夯处理后的某深厚人工填土地基,由于建筑物施工过程中发生了不均匀沉降和开裂,因此,需对其进行进一步的加固处理。袖阀管注浆能较好地控制注浆范围和注浆压力,可进行重复注浆,且发生冒浆与串浆的可能性小。本文即对该人工填土地基采用袖阀管注浆处理,取得了较好的效果,达到加固目的,对类似工程具有一定的参考意义。

After heavy tamping treatment of a deep artificial filled soil, due to uneven settlement and cracking oc- curred in the building construction process, therefore, it needs further reinforcement. Sleeve valve pipe can better control the scope and grouting pressure grouting, be repeated grouting, and the small possibility of mud spillover and grout leaking etc. In this paper, the sleeve valve tube grouting is used for reinforcing this artificial filled soil foun- dation, which achieves good effect, the purpose of reinforcement, and has a certain guiding significance for similar engineering.
