目前,世界上许多先进国家都非常重视锚杆支护的应用。法国每年要使用700万根锚杆。锚杆的种类大致可以分为楔缝式、涨圈式和粘结式,粘结式又分为树脂粘结式和砂浆粘结式两种。目前国外主要采用涨圈式和树脂粘结式两种。锚杆支护机械化对锚杆支护的发展起了一定的推动作用,仅美国就有8个以上的公司出售锚杆支护机械系列产品。除锚杆安装机具外,锚杆支护机械均是在凿岩机械基础上发展起来的。但是,由于锚杆支护机械的特殊需要,又与普通凿岩机具不同,特别是兼赋锚杆打眼安装的综合性设备。因此,锚杆支护机械是一种单独的系列产品。
At present, many advanced countries in the world attach great importance to the application of bolt support. France uses 7 million bolts annually. The types of bolts can be roughly divided into wedge type, ring up and bonding, bonding and resin bonding is divided into two types of mortar bonding. Currently mainly used up ring and resin bonded two. Bolting and bolting mechanization has played a certain role in promoting the development of bolt support. Only the United States has more than eight companies selling bolt support machinery products. In addition to bolt installation of machinery, bolt support machinery are developed on the basis of rock drilling machinery. However, due to the special needs of bolt support machinery, but also with ordinary rock drilling equipment is different, especially with eyebolt and eye-mounted installation of integrated equipment. Therefore, bolt support machinery is a separate series of products.
