Abstract
The utility model belongs to a driven-in post-grouting hollow anchor rod, comprises a grouting pipe, more than two steel reinforcements and a reinforcing connecting piece, and is characterized in that equidistant grouting holes are chiseled on the grouting pipe, on the exterior surface of which steel reinforcement is fixed, and the reinforcing connecting piece is provided for the connection of every two steel reinforcements. The utility model is easy to form holes in sand and water, has strong bearing capacity and full grouting, thereby greatly improving engineering quality. The anchor rod belongs to the driven-in type and the grouting channel is completely in the center, thereby grouting can wrap the anchor rod evenly, which avoids the danger of erosion and achieves the purpose of long-time support; the driving speed of the anchor rod is greatly larger than the speed of boring, thereby the anchor rod also has the advantages of convenient construction with construction period and cost being saved.
Description
Technical field: the utility model belongs to the anchor pole of using in the construction work.
Background technology: used anchor pole adopts first boring more in the civil works at present, and reinforcing bar is put into again in duct slip casting in the back in boring good duct, form anchor pole.This kind anchor pole exists in sand, pore-forming difficulty under water; Steel bar stress is stressed unreasonable; Shortcomings such as supporting capacity is relatively low.
Summary of the invention: the purpose of this utility model provide a kind of in sand, all can construct the formula of the squeezing into grouting behind shaft or drift lining hollow bolt that supporting capacity is strong under water.The technical solution of the utility model is: the utility model comprises Grouting Pipe, two above reinforcing ribs, part reinforces the connection, be characterized in: the Grouting Pipe equal intervals have an injected hole, reinforcing rib is fixed on the external surface of Grouting Pipe, is connected with the part that reinforces the connection between per two reinforcing ribs.There is not the problem that is difficult for pore-forming in the utility model in sand He in the water, bearing capacity is strong, and slip casting is full, has improved workmanship greatly, because this anchor pole is to squeeze into formula, and the slip casting duct is fully in the centre, and slip casting can evenly be wrapped up the anchor pole total length, has avoided the danger of corrosion, can reach the purpose of long-term supporting, because this anchor pole is squeezed into speed and is far longer than penetration rate,, save the advantage of duration and cost so this anchor pole also has easy construction.
