预应力让压锚杆TRY-B：TRY-B Pre-st

try-b预应力让压锚杆：
在try-a的特点基础上可以体现二次让压,根据不同的锚杆抗拉强度设置第一次让压x吨,第二次让压y吨。

try-b pre-stressed yield bolt：
can embody repeated on the try-a characteristic basis by pressure. tensile strength interposing the first time according to different bolt by ton , first time by pressure x and second by pressure y ton.

山东同瑞矿业科技有限公司是矿山企业非常认可的岩层控制产品供应商。同瑞生产的预应力锚杆安全可靠，有适应不同地质采矿条件承载力100kn-395kn系列锚杆。

shandong tongrui mining technology co., ltd is a recognized strata control mining company in the entire products supplier of the mining field. anchor production is safe and reliable. the mining conditions 100kn-395kn series bolt have adaptive capacity of different geologic.

try-a预应力让压锚杆：

try-a pre-stressed yield bolt

通过螺母中的精铸阻尼准确达到搅拌树脂锚固剂的作用，然后施加预应力

damping through the nut in the casting resin anchor agent precisely to the role of stirring, and then pre-stressed.

让压装置是在高地压的情况下，让压管能够变形让压、缓冲和释放围岩的压力，达到保护锚杆不受损害的作用。使巷道的支护效果更好更安全。

let pressure device in a high pressure situation, so that yield tube can be deformed to pressure, buffer and release the pressure of surrounding rock in order to protect against damage to the role of anchor. in order to get a safety of the laneway supporting.
