Split Set

Description:

Split Set Bolts is an efficient and reliable Friction Rock Anchor (Friction Rock Anchor), which is widely used in mining and tunnel support projects. Manufactured from high-strength steel, these bolts provide excellent support through a unique wedge design that expands quickly and tightly against the rock wall during installation, creating a strong friction force.Split Set Bolts are quick and easy to install without the need for resins or other adhesives, which greatly improves construction efficiency. In addition, Split Set Bolts have excellent corrosion resistance and long-term stability, maintaining their performance in harsh geological conditions. Whether used for temporary or permanent support, Split Set Bolts provide reliable safety in mines and tunnels. This advanced shoring technology not only improves safety, but also significantly reduces maintenance costs, making it an ideal choice for modern mining and civil engineering.

Details of Slit Tube Anchor

Slit pipe anchor is a new type of anchor with full-length anchorage and active reinforcement of surrounding rock, its three-dimensional part is a longitudinal slit high-strength steel pipe, when installed in a slightly smaller than the diameter of the pipe drill hole, it can immediately exert radial pressure on the hole wall over its full length and friction to prevent the surrounding rock from sliding down, coupled with the bearing force of the anchor tray pallet, so as to keep the surrounding rock in a three-way force state and realize the rock layer greatness. In the case of blasting vibration surrounding rock anchor shift, etc., there is a significant increase in the late anchoring force, when the surrounding rock is significantly displaced, the anchor does not lose its support resistance, it has better characteristics than the rising shell type anchor. The drilling depth of the seam pipe anchor should not be less than the effective length of the anchor rod body, but the depth of the over-length value should not be more than 100mm. drilling holes should be kept in a straight line, and the drilling direction of the system anchor should be perpendicular to the excavation surface, and it should be as large as possible to make a larger angle of intersection with it when the rock layer level or the main structural surface is obvious, but the perpendicular deviation from the excavation surface should not be more than 20°; the local anchors should be as large as possible to make a large angle of intersection with the rock layer level or the main structural surface. intersect. Moreover, the arrangement of sewing pipe anchor is relatively centralized, and the construction of external waterproofing under the basement floor is also more convenient; for the case of insufficient bearing capacity of individual self-propelled anchors, there is strong resistance due to the sharing of more self-propelled anchors.

Company strength:

Equipment first strength company has 16 senior engineers, 38 technicians, 150 mechanics, professional product designers, and has advanced production equipment to meet your needs for use.

Precautions for installation of sewing tube anchor:

1、Before loading anchoring medicine roll, first insert the anchor into the hole to test the depth of the anchor eye, to see whether the depth of the hole meets the requirements, if the depth is not enough, the eye should be re-drilled to meet the requirements until.

2、Installation, firstly, load the anchoring rolls into the eye according to the specified quantity (use 2 rolls), and then insert the anchor rod. At this time, set up the connecting sleeve, insert the wind anchor, start the wind anchor to rotate, slowly advance to the bottom of the eye, stir 20s, stop drilling, remove the wind anchor, wait for 5min before removing the connecting sleeve. 20min later, put on the pallet, tighten the nut with a wrench.

3, the pallet should be tightly attached to the rock wall, if the rock wall is not flat, use handaxe to level it first, and then install it.

4、Its anchoring force shall not be less than 50KN/root.
