高压旋喷灌浆技术在钢板桩工程中的应用

洪湖钢板桩工程中在垂直铺塑与钢板桩两种工法联接处，采用高压旋喷桩墙形成封闭防渗体系。施工过程中，为保证质量，加强对中间关键环节的控制、检查，对出现的问题及时采取处理措施，有效地保证了工程质量。经开挖自检和钻孔检查，合格率100%，优良率75%，工程质量优良。施工结果表明，钢板桩和垂直铺塑接头处采用高压旋喷灌浆技术构筑防渗体是成功的。它具有效果好、速度快、质量有保证、经济适宜等特点，与其它工法相比具有明显的优势。

Application of high-pressure rotating jet grouting technology in steel sheet pile construction

In the construction of steel sheet pile works in the Honghu flood control dyke,high-pressure rotating jet grouting technology was used to build a close seepage control system's pile wall at the joint of steel sheet pile with vertical composite geomembrane.In order to guarantee project quality,strengthen the controlling and examination of intermediate key construction links,some measures were timely taken for solving problems arising in construction.Inspection by excavation and boring showed good project guality with 100% projects being up to standard and 80% projects being excellent.The seepage control body constructed by using high-pressure rotating jet grouting technology at the joint of steel sheet piles with vertical composite geomembane is successful,and is characterized by good results,high-speed construction,reliable quality and reasonable cost,etc.This construction method has remarkable superiority compared with other ones.
