土工格室是由高强度的HDPE或PP共聚料宽带,经过强力焊接或铆接而形成的一片网状格室结构。它伸缩自如,运输时可缩叠起来,使用时张开并充填土石或混凝土料,构成具有强大侧向限制和大刚度的结构体。经试验和现场应用证明,在提高一般填土承受动荷以及路基防护方面均有很大的功效,可广泛应用于各类软弱地基处理,提高地基的承载能力。文章主要结合上海市红旗塘堤防维修工程局部路基处理方案对比分析,探讨土工格室在道路路基处理工程中的应用。
Geocell is a high-strength HDPE or PP copolymer broadband, welded or riveted to form a mesh cell structure. It stretches freely and can be folded up during transport. When used, it is opened and filled with soil or concrete material to form a structure with strong lateral restraint and high rigidity. The test and field application proves that it has a great effect in improving the load of normal fill and the roadbed protection and can be widely applied to various types of soft foundation treatment to improve the bearing capacity of the foundation. The paper mainly analyzes the application of geocell in the treatment of road subgrade based on the comparative analysis of local subgrade treatment schemes of Hongqi pond dike maintenance project in Shanghai.
