Information

  The hollow grouting bolt of the hollow bolt manufacturer is composed of a hollow bolt body, a hard plastic anchor head, a stop plug, a spacer and a nut: the steel expansion shell hollow grouting bolt is made of a hollow bolt body, steel The expansion shell anchor head, the grouting plug, the spacer block and the nut are composed; the S-type hollow grouting anchor rod is composed of a hollow bolt body, a self-advancing twist drill, a connecting sleeve, a grouting plug, a spacer block and a nut.

Hollow bolt manufacturers

  The prestressed steel bar hollow-entry grouting anchor rod consists of a hollow anchor rod body, self-advancing twist drill, connecting sleeve, centralizer, PE waterproof casing, self-derived rigid waterproof casing, grouting plug, spacer and nut constitute.

  The hollow grouting anchor rod of the hollow anchor rod manufacturer has the following characteristics, and then the firmness and compliance of the anchor cable have been greatly developed. The shallow hollow grouting anchor rod is first pierced into the hollow rod body, and then cement mortar is poured into the cavity of the hollow rod body from the inner type to the outside, and the outer port number of the anchor hole has a stop plug and a backing plate, which can prevent the slurry reasonably The outflow.

Hollow bolt

  The hollow bolt manufacturer’s loan guarantees the rich grouting between the rod body and the edge of the hole, how can it transmit the shear stress and tensile stress along the total length of the anchor cable, and ensure that the rock within the limitation of the steel anchor can be structurally strengthened. When required, working pressure grouting can also be implemented to make the grout wet and loosen the cracks in the rock near the rod body, so that the rock within the limitation of the reinforcement anchor can be further strengthened.

  After grouting the cohesive force of the hollow anchor rod manufacturer, the nut can be tightened with a torque wrench, and the resistance of the backing plate of 10KN up and down is formed at the edge of the anchor cable. It has a spherical working pressure zone similar to that of the foot-operated anchor cable, and then the rock can be controlled. The early deformation after the excavation of the foundation pit prevents the collapse of the rock mass from falling. Use expanded shell hollow grouting anchor or prestressed steel self-advancing hollow grouting anchor.
