Rope the inner anchor is in the steady soil of abrupt slope slopes or basement rock.
The anchorage cable anchoring segment length is 4~10m, and outer anchor segment length is 1.5m, per hole anchor cable by 4~10 beam φ
15.2mm high intensity（Intensity is not less than 1860Mpa）, underrelaxation steel strand manufacturing form, the bore diameter of the anchor cable is 110
Between~150mm, 10~35 ° of angle of declination, grouting pressure is not less than 0.6MPa, and anchor cable carries out tensioning, opens for the first time step by step by several times
Drawing should could carry out after joist concrete strength reaches design strength 75%.
The retaining wall can use standard collective drawings-- to face upward in inclined, folding back of the body formula, load retaining wall, inclined of bowing, vertical type
Any one.
The beneficial effects of the utility model：The advantages of compared with existing pile foundation joist earth-retaining wall technology, mainly has, and pore-forming is set
It is standby light, compact, flexible, it is not high to site requirements, various complicated landform, geological conditions are adapted to, is conducive to multiple devices
Construct at the same time, convenient and efficient, short time limit, low cost, it is applied widely the advantages that.
