树脂锚固剂
树脂锚固剂是由不饱和聚酯树脂、固化剂、促进剂和其它辅料，按 定比例配制而成的粘稠状锚固粘接材料，由聚酯薄膜分割包装呈药卷状，具有常温固化快，粘接强度高，锚固力可靠和耐久力好等 良性能。
Resin anchoring agent is a viscous anchoring and bonding material prepared by unsaturated polyester resin, curing agent, accelerant and other auxiliary materials in a certain proportion. It is divided and packaged by polyester film in the form of drug roll. It has good properties such as fast curing at room temperature, high bonding strength, reliable anchoring force and good durability.
与不同材质的杆体配套使用所形成的树脂锚杆是现代锚固工程中的.佳材料。除在地下工程及边坡支护中应用外，在立井的装备安装、建筑物的构件连接、设备基础的锚固等均得到广泛的应用，并获得满意的技术经济效果。
The resin bolt is the best material in modern anchoring engineering. In addition to the application in underground engineering and slope support, it has been widely used in the installation of shaft equipment, the connection of building components, and the anchoring of equipment foundation, and has achieved satisfactory technical and economic results.
预紧力的作用
(1)预紧力能够发挥锚杆主动支护作用，特别是在层状岩层、破碎围岩条件下，增大预紧力能够改变围岩性质，防止围岩破坏，保持围岩稳定，有利于对围岩支护。
(1) Pre tightening force can play an active role in bolt support, especially under the condition of layered rock and broken surrounding rock, increasing pre tightening force can change the nature of surrounding rock, prevent the destruction of surrounding rock, maintain the stability of surrounding rock, and is conducive to the support of surrounding rock.
（2）锚杆预紧力大小对顶板稳定性具有决定性的作用。当预紧力大到 定程度时，锚杆长度范围内和锚杆长度以上的顶板离层可以得以消除。
(2) The pre tightening force of bolt plays a decisive role in the stability of roof. When the pretension is large to a certain extent, the roof separation within the anchor length and above the anchor length can be eliminated.
（3）高预紧力锚杆旨在建立预应力顶板，预应力顶板的存在在 定程度上保护着顶板使其免受水平应力的破坏，使顶板岩层处于横向压缩的状态，以克服高水平应力对顶板稳定性的影响。
(3) The purpose of high pretension bolt is to establish prestressed roof. The existence of prestressed roof to a certain extent protects the roof from the damage of horizontal stress, and makes the roof strata in the state of transverse compression, so as to overcome the influence of high level stress on the stability of roof.
(4)预应力结构的形成是有条件的，锚杆预紧力是关键。在水平应力大的条件下，锚杆的作用在于给顶板及时提供很高的预应力以形成预应力顶板，形成 个压力自撑结构。
(4) The formation of prestressed structure is conditional, and the pre tightening force of anchor is the key. Under the condition of large horizontal stress, the role of anchor bolt is to provide high prestress to the roof in time to form a prestressed roof and a pressure self-supporting structure.
