摘要
上海采用先促淤、后圈围方式实施圈围工程时,部分促淤坝临近海塘,或成为海塘的一部分。促淤坝与海塘间的反滤结构由于种种原因而损坏,致使堤身(堤基)土方流失、大方脚或护坡塌陷、开裂等,危及海塘安全。为确保海塘的正常运行与防汛安全,海塘堤身土方防渗维修尤为重要。本文以高压旋喷桩为例,对防渗维修设计,施工及质量检测进行探讨,为今后解决海塘堤身土方防渗维修措施提供参考和借鉴。
After the implementation of sedimentation promotion and enclosure procedure for land recalmation project, a partial sedimentation promotion dam became a part of the seawall. Brought about soil loss and even spread footing damage, which increasingly raised seawall safety concerns. In this essay, the author makes a tentative study on the application of high pressure jet grouting, hoping to provide references for the seawall maintenance.
