Water taking pump room cement jet grouting pile water stop enclosure structure and construction method thereof
The invention discloses a water taking pump room cement jet grouting pile water stop enclosure structure and a construction method thereof. The technical problem that in the prior art, a quicksand layer cannot be reasonably blocked, and therefore the designed bearing capacity requirement of the bottom of an open caisson cannot be met is solved. The water stop enclosure structure comprises a first cement jet grouting pile and a second cement jet grouting pile. According to the construction method, a cement jet grouting method is adopted for cement jet grouting pile grouting, site leveling and surveying and setting out are conducted on a construction site, drilling is conducted according to measurement marks, and jet grouting is conducted in drilled holes. According to the water stop enclosure structure, cement jet grouting pile construction is adopted to reinforce an open caisson foundation soil body, a quicksand layer can be effectively blocked, open caisson sinking construction is not affected, after the open caisson sinks in place, the cement jet grouting piles can play a role in stabilizing a foundation bearing layer, the open caisson is prevented from deviating due to the influence of a riverbed, the cement jet grouting piles are good in integrity, in the construction process of the open caisson of the water taking pump room, the quicksand layer can be reasonably blocked on the basis of ensuring smooth sinking of the open caisson so as to meet the design bearing capacity requirement of the bottom of the open caisson.
本发明公开了取水泵房水泥旋喷桩止水围护结构及其施工方法，解决现有技术不能合理阻断流沙层从而满足不了沉井底部所设计承载力要求的技术问题。本发明止水围护结构包括第一水泥旋喷桩和第二水泥旋喷桩。施工方法采用水泥旋喷注浆法进行水泥旋喷桩注浆，在施工场地进行场地平整并测量放线，根据测量标注进行钻孔，往钻孔中进行旋喷注浆。本发明采用水泥旋喷桩施工对沉井基础土体进行加固，可有效阻断流沙层，并不影响沉井下沉施工，沉井下沉到位后，水泥旋喷桩可起到稳定基础持力层的作用，防止沉井受河床影响偏移，水泥旋喷桩整体性好，在取水泵房沉井施工过程中保证沉井顺利下沉的基础上能够合理阻断流沙层以满足沉井底部设计承载力要求。
