高压旋喷桩内插预应力钢筋混凝土方桩围护体系的设计与施工

Design and Construction of High-pressure Rotary Jet Grouting Pile Embedded with Pre-stressed Reinforced Concrete Squared Pile Enclosure System

摘要:

在充分分析比较传统深基坑围护体系优劣的基础上，将高压旋喷止水帷幕与预应力钢筋混凝土方桩相结合，设计创新出一种新型的围护体系，且将之运用于工程实例中，大大降低了工程成本，创造了巨大的经济效益。

Abstract:

Based on the analysis and comparison of advantages and disadvantages of traditional deep foundation pit enclosure systems, a new enclosure system was created by combining high-pressure jet grouting curtain with pre-stressed reinforced concrete square pile, which was applied in the projects, and the construction cost was greatly reduced with huge economic benefits.
