Full threaded steel self drilling rock bolt / hollow anchor bar / anchor rods price
Product Description
Currently used to support many different types of anchors, its length anchoring and splitting supports can be divided into the class set of anchor bolts and bolt full-length classes. Only a part of the contact between the anchor device and the finger rod and the hole wall of the anchor bolt. Incline fixation, anchor point and local anchorage, etc. The total length of anchor bolt type refers to the total length of the anchor device or anchor rod in contact with the whole hole wall of the anchor bolt, including friction rock bolt, anchor mortar, cement and resin bolt, etc. Anchor bolts can be divided into mechanical anchorage type and anchor key type.
Hollow grouting bolt and the wall of the contact hole, through the friction from the anchor bolt action, is mechanical anchor bolt; The whole length of the bolt hole wall bond, which is held together by adhesive force, acts as an anchor bolt belonging to the joint bolt, either using resin mortar, quick-hardening cement or other cement materials. According to the anchoring materials used to produce a variety of types of bolt materials, it can be divided into cable anchor, ordinary steel bolt, steel bolt, glass fiber reinforced plastic bolt, wood and bamboo anchor bolt and other types.
Hollow bolt is not only a bolt, it is similar to the combination of ordinary bolt and grouting pipe. It is also very convenient to use and not as complicated as the traditional bolt. The structure of the hollow bolt, as its name suggests, is hollow in the middle. Convenient for grouting. From the mechanical point of view, it is mainly to improve the cohesion C and internal friction Angle φ of surrounding rock mass.
In essence, the bolt is located in the rock and soil body and forms a new complex. And at present the market price of hollow bolt has been close to ordinary bolt. The bolt in this complex solves the shortcoming of low tensile capacity of surrounding rock mass. Thus, the bearing capacity of rock mass itself is greatly strengthened.
Using hollow bolts will avoid some of the hazards caused by the bolts and will allow the construction to be completed on time. It is also used for active reinforcement of slopes, tunnels and DAMS in engineering technology. The surrounding rock of the roadway is bound together so that the surrounding rock itself
