本文介绍了一种碗扣型扣件连接正交、回转扣件连接斜交构件,适用于铁路路基各种坡度的护坡、挡土墙施工的新型工具式脚手架——HPJ型护坡脚手架。此种脚手架综合了楔紧连接的碗扣式脚手架与螺纹连接的扣件式钢管脚手架的优点,安装便捷,使用安全,寿命周期成本低,是铁路路基护坡、挡土墙理想的施工装备。
In this paper, a new type of tool scaffolding, HPJ-type revetment scaffolding, is introduced, which is a kind of bowl-type fasteners connected orthogonally and the swivel fasteners are connected with bias members for slope protection and retaining wall construction. The scaffolding combines the advantages of wedge-fastening bowl-shaped scaffolding and threaded fastener-style steel scaffolding. The utility model has the advantages of convenient installation, safe use and low life cycle cost, and is an ideal construction equipment for railway roadbed slope protection and retaining wall.
