【摘要】 基于长螺旋搅喷桩用于基坑帷幕工程的工程案例,证明护坡桩+桩间水泥土桩是一种很好的基坑帷幕隔水形式,而长螺旋搅喷桩在实现桩间水泥土桩和确保其与护坡桩搭接质量方面要优于传统的旋喷桩和搅拌桩。在基坑施工过程中,改变护坡桩与长螺旋搅喷桩的施工顺序,能克服护坡桩施工过程中因塌孔、桩位和垂直度偏差给长螺旋搅喷桩施工带来的困难,既可保证帷幕隔水质量,又能取得较好的社会效益和经济效益。更多还原

【Abstract】 Based on the example of using the long spiral rotary jetting and mixing pile as waterproof curtain,the slope protection piles combined with the cement soil piles are proved as a good form of waterproof curtain.The long spiral rotary jetting and mixing pile is better than the traditional jetting pile or the mixing pile at combining with the protection piles.The process of the protection pile and the jetting and mixing pile is changed during the construction.It can overcome the difficulty of the collapse,pile spacing and verticality deviation.The waterproof quality,social benefits and economic benefits are ensured.更多还原
