基坑支护的挡土桩在建设工程的地下部分建设完成后就不起作用了,成为废料。而且挡土桩的经济成本比较高,在地下工程中所占比例也很大。对于挡土桩的利用,现根据工程实例具体的介绍了挡土桩作为地下室外墙的一部分及工程桩在工程中的应用。通过应用将很大程度上降低地下部分的建设成本。 Retaining piles supporting foundation pit in the construction of the underground part of the construction is completed, it will not work, as waste. And the high cost of retaining the pile, underground engineering in a large proportion. For the use of retaining piles, according to project examples are introduced concrete retaining piles as part of the basement wall and engineering piles in the project application. Through the application will greatly reduce the underground part of the construction costs.
