Pile anchor reinforcing device penetrating through soft rock stratum and construction method of pile anchor reinforcing device
The pile anchor reinforcing device penetrating through the soft rock stratum comprises a vertical pile, an inner sleeve, an outer sleeve and an anchor cable, through holes are evenly formed in the outer wall of the outer sleeve, the outer sleeve is obliquely and downwards inserted into the soft rock stratum, the inner sleeve is arranged in the outer sleeve in a sleeved mode, and the space between the outer sleeve and the inner sleeve is filled with cement mortar; a waist beam is arranged on the side face of the vertical pile, one end of the anchor cable penetrates through the inner sleeve and is anchored to the sandstone layer, and the other end of the anchor cable penetrates through and is anchored to the waist beam. The anchor cable and the inner sleeve are connected in a clearance fit mode. The invention further discloses a construction method. The inner sleeve is fixedly arranged in the outer sleeve, the lower section of the anchor cable is anchored in the sandstone layer, and the upper section of the anchor cable is in clearance fit with the inner wall of the inner sleeve, so that the anchor cable does not act on the inner sleeve and further does not act on the outer sleeve, and therefore it is guaranteed that the anchor cable does not disturb and damage the soft rock stratum.
本发明公开了一种穿过软弱岩层的桩锚加固装置,包括竖桩、内套管、外套管和锚索,所述外套管的外壁上均匀开有通孔,所述外套管倾斜向下插入软弱岩层内,内套管套设于外套管内,且外套管与内套管之间的空间填充有水泥砂浆;所述竖桩的侧面上设有腰梁,所述锚索的一端穿过内套管且与砂岩层锚固,锚索的另一端穿过且与腰梁锚定连接;所述锚索与内套管之间为间隙配合连接。本发明还公开了一种施工方法。本发明采用在外套管内固设内套管,并且锚索的下段锚固在砂岩层中,而锚索的上段与内套管的内壁之间为间隙配合,使得锚索不会作用于内套管,进而也不会作用于外套管,从而保证锚索不会对软弱岩层产生扰动和破坏。
