在现代锚固联接技术中,应用高分子合成树脂的粘结特性,实现锚杆(筋)的锚固功能是一个技术进步。使用树脂锚固的锚杆称为树脂锚杆,具有化学组成的复合粘结材料称为树脂胶泥(锚固剂)。 由于树脂锚杆有常温快速固化、锚固力可靠、施工简单、节省费用等优点,因此除用于矿山锚喷支护外,在竖井井筒装备安装工程、建筑物抗震加固及设备基础锚固等方面均有广泛的应用,取得显著的技术经济效果。据初步调查统计,应用树脂锚杆安装井筒装备,可节省费用10％,缩短安装工期2/3,而用树脂锚杆加固楼房可节省费用30％以上。
In modern anchoring and joining technology, it is a technological advancement to apply the bonding property of polymer synthetic resin to realize the anchoring function of anchors (tendons). Bolts anchored with resin are called resin anchors, and composite bonding materials with a chemical composition are called resin mashes (anchoring agents). Because of its quick curing at normal temperature, reliable anchoring force, simple construction and cost saving, the resin bolt has the following features: In addition to being used for supporting the mine bolt and shotcrete, the shaft and shaft equipment installation engineering, building seismic strengthening and equipment foundation anchoring Has a wide range of applications, achieved significant technical and economic results. According to the preliminary investigation and statistics, the application of resin bolt to install the wellbore equipment can save 10% of the cost and shorten the installation period by 2/3, while using the resin bolt to reinforce the building can save over 30% of the cost.
