Anchor rod supporting structure for reinforcing railway embankment slope and construction method thereof
The invention discloses an anchor rod supporting structure for reinforcing a railway embankment slope and a construction method thereof, and belongs to the technical field of anchor rod supporting. The anchor rod supporting structure for reinforcing the railway embankment slope is characterized in that a pressure bearing plate is fixed on a mounting component and arranged on the ground, tensile reinforcements and connecting pieces are alternately fixed up and down, the uppermost tensile reinforcement is connected with the mounting component, and the lowermost connecting piece is connected witha rotary shaft with a bulge on the lower end surface and a stirring wing, anti-rotating wings and excavating wings on the circumferential surface. According to the construction method, design valuesand specifications of bending moment, shearing force and axial force borne by an anchor rod body are calculated; a top end digging and cutting mechanism is connected with a drilling machine, cement isinjected and stirred during drilling, and the top end digging and cutting mechanism stops working after complete drilling and is reversely screwed out; the top end digging and cutting mechanism is connected with the tensile reinforcements, meanwhile, cement is injected and stirred, and working is stopped after complete drilling; and the tensile reinforcements are added, drilling is repeated tillthe preset depth is reached, and the anchor rod supporting structure is fixed. According to the anchor rod supporting structure for reinforcing the railway embankment slope and the construction methodthereof, the number of pipelines is reduced, the construction time is shortened, the number of anchoring parts are reduced, the stability of a track is ensured, and the stirring efficiency of the soil and the cement is improved.
一种用于铁路路堤边坡加固的锚杆支护结构及其施工方法，属于锚杆支护技术领域。承压板固定在安装构件上且设在地表上，抗拉钢筋与连接件上下交替固定，最上端抗拉钢筋与安装构件连接，最下端连接件与下端面有突起、圆周面有搅拌翼、防旋翼及挖掘翼的回转轴连接。计算锚杆本体所受弯矩、剪力、轴向力设计值及规格，将顶端掘削机构与钻孔机连接，在钻入时注入水泥并搅拌，完全钻入后停止工作并反向旋出，连接顶端掘削机构及抗拉钢筋，同时注入水泥并搅拌，完全钻入后停止工作；增加抗拉钢筋，重复钻入直至达到预定深度，将本发明进行固定。本发明减少了管道数量、施工时间、锚固件的数量，保证了轨道的稳定性,提高了对土壤水泥的搅拌效率。
