摘要
桩锚式支挡结构在基坑支护、边坡防治等岩土工程防治领域中广泛应用。针对传统锚式支挡结构的腰梁存在受力不均、腰梁与支护桩之间施工间隙等问题,提出了一种桩锚连接新装置,介绍了装置的结构、受力性能和施工方法。该装置有效解决了锚索预应力传力不均的弊端,加强了桩锚支护体系的整体性,更大程度节约了钢材的使用量,同时可以提高支护体系的安全性,在桩锚支护体系中具有较高的应用价值。
The anchored retaining structure is widely used in the field of geotechnical engineering prevention and control,such as foundation pit support and slope prevention.In view of the problems existing in the traditional anchor retaining structure,such as the uneven stress on the waist beam and the construction gap between the waist beam and the supporting pile,a new device for the connection of pile and anchor is provided,and the structure,stress performance and construction method of the device are introduced.The device can effectively solve the problem of uneven prestressed force transmission of anchor cable,strengthen the integrity of the pile anchor support system,save the use of steel to a greater extent,and improve the safety of the support system,which has high application value in the pile-anchor support system.
