土层锚杆由联邦德国于1958年首次应用于深基础的支护工程。由于它具有许多优点,在世界各国已普遍推广。它不仅用于临时性支护,而且在永久性建筑工程中也获得了广泛应用。我国近年来深基础工程日益增多,当深基础邻近有建筑物、交通干线或地下管线,基坑开挖不允许放坡时,采用单层或多层土层锚杆支承护墙,可以简化支撑,改善施工条件,加快施工进度。
The soil anchors were first applied to deep foundation support works by the Federal Republic of Germany in 1958. Because of its many advantages, it has been widely promoted in countries all over the world. It is not only used for temporary support, but also has been widely used in permanent construction projects. In recent years, China’s deep-rooted projects have been increasing. When deep foundations are adjacent to buildings, traffic trunks, or underground pipelines, and slopes are not allowed to be sloped during excavation, single-layer or multi-layer soil bolts can be used to support the retaining wall, which can simplify support. , improve the construction conditions and speed up the construction progress.
