Guard post for rail transit construction
The invention belongs to the field of rail construction, and particularly relates to a fender post for rail transit construction, which comprises an iron cage net, the bottom end of the iron cage net is fixedly connected with a fixed bottom plate; the side surface of the fixed bottom plate is annularly and fixedly connected with a flat arc plate; the cross section of the leveling arc plate is designed to be in an obliquely upward arc shape; a contact block is arranged at the bottom of the fixed bottom plate; the bottom of the contact block is arc-shaped; through the structural design that after a contact block makes contact with the bottom of the pile pit, the iron cage net continues to press a fixing bottom plate, a blade at the end of a sliding block cuts off a first pull rope, then a spring pushes out a soil vibration block, soil on the side wall of the pile pit is smashed down, and the contact block is fixed, the function of fixing the iron cage net in the pile pit is achieved; the problem that the strength of the fender post is affected due to the fact that the iron cage net inclines when being put into the pile pit is effectively solved.
本发明属于轨道施工领域，具体的说是一种轨道交通施工用围护桩，包括铁笼网；所述铁笼网的底端固接有固定底板；所述固定底板的侧面呈环形固接有置平弧板；所述置平弧板的截面为斜向上的弧形设计；所述固定底板的底部设有接触块；所述接触块的底部为圆弧形设置；通过在接触块与桩坑底部接触后，铁笼网继续压动固定底板，使得滑动块端部的刀刃将第一拉绳切断，进而使得弹簧将振土块推出，将桩坑侧壁上的土壤砸下，对接触块进行固定的结构设计，实现了可对桩坑内部的铁笼网进行固定的功能，有效的解决了铁笼网在放入桩坑内部时出现倾斜，导致围护桩的强度受到影响的问题。
