Mudstone stratum shield tunnel portal slope supporting mechanism and supporting method
The mudstone stratum shield tunnel portal slope supporting mechanism comprises a pressing frame structure, an inner frame structure and a stabilizing structure, concrete is injected into a soft soil layer from seepage holes, after the concrete is solidified into a solid state, a nut is rotated to drive a partition pad, a transverse frame and a longitudinal frame at the bottom of a pressing frame to be pressed downwards to the degree that the partition pad, the transverse frame and the longitudinal frame make full contact with a protective embankment, and then the stable structure is formed; the mud rock stratum shield tunnel slope is supported, then the sleeve frame and the pressing net are pressed downwards to the height making contact with the protective embankment through the U-shaped limiting holes, water and soil loss is limited, the screw is rotated clockwise to fix the height, and the influence of poor mechanical properties of soft soil can be effectively reduced through the pulling force of the hollow limiting screw on the pressing frame; the problems that the connecting position of the slope supporting structure and the surface of the slope is loosened, and the protecting and supporting capacity of the supporting mechanism to the slope is lowered are solved, and the stability of the tunnel slope is effectively guaranteed.
本发明公开了一种泥岩地层盾构隧道洞口边坡支护机构及支护方法，包括压框结构，内架结构，稳固结构，将混凝土从渗孔内注入软土层，等待混凝土凝固为固态后，旋转螺母带动压框底部的隔垫，横架和纵架下压到充分接触防护堤的程度，对泥岩地层盾构隧道边坡进行支护，而后通过U形的限位孔将套框和压网下压到接触防护堤的高度，限制水土的流失，顺时针旋转螺杆固定高度，通过中空限位螺杆对压框的拉力，能够有效降低受软土较差的力学性质的影响，导致边坡支护结构与边坡表面连接处产生松动，造成支护机构对边坡的防护支撑能力下降的情况出现，有效保障了隧道边坡的稳定性。
