Description
Technical field
The utility model relates to Geotechnical Engineering support technology field, is specially a kind of Novel hollow grouted anchor bar.
Background technology
In the domain engineering processs of construction such as tunnel, water conservancy, mine working, anchor pole becomes most widely used support apparatus.Hollow grouting anchor is a kind of conventional supporting tool, buried underground in the earth formation, stratum can be chained together tightly, interaction by anchor pole injecting cement paste one by one hole wall rock mass power one by one, transfer and improve self-strength and the self-stable ability of Rock And Soil, improve by the stress state of anchoring Rock And Soil to make it stable, thus reduce the deflection in tunnel.
But, major part anchor pole is used in total length supporting or the reinforcing aspect of stratum or works, i.e. one anchor pole total length all plays supporting power effect, and disengaging section parts such as excision exterior portion anchor bar body cannot realize mass action or weakens its effect or cause anchor pole not reuse to cause waste.In Practical Project, some engineering stage by stage or implement step by step and just can complete, therefore only to need a part of anchor pole to need to play long term, and remaining then can reclaim.
Utility model content
The purpose of this utility model is to provide a kind of Novel hollow grouted anchor bar, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，The utility model following technical scheme of offer: a kind of Novel hollow grouted anchor bar，Including anchor head、First hollow bolt、Adapter sleeve、Second hollow bolt、Stop grouting plug、Backing plate、Nut、Little grouting port、Grouting pipe and little grouting pipe，Described anchor head upper weld has the first hollow bolt，Described first hollow bolt top is provided with adapter sleeve，Second hollow bolt is installed on described adapter sleeve，On described second hollow bolt, stop grouting plug is installed，Described stop grouting plug top is provided with backing plate，Described backing plate top is provided with nut，Described nut sleeve is contained on the second hollow bolt，Little grouting port it is provided with on described anchor head，Described first hollow bolt、It is provided with grouting pipe inside second hollow bolt and anchor head，Described anchor head is internally provided with little grouting pipe，Described little grouting pipe one end communicates with grouting pipe，The other end connects little grouting port.
Preferably, described first hollow bolt and second hollow bolt one end are provided with joint, and described joint is provided with screw thread, and described adapter sleeve is internally provided with the screw thread matched with the screw thread on joint.
Compared with prior art, the beneficial effects of the utility model are: the first hollow bolt and the second hollow bolt are connected into an entirety by adapter sleeve by the utility model, while saving material, it is also convenient for the assembly and disassembly of anchor pole, can the most arbitrarily be combined, facilitate site operation, efficiently solve hollow grouting anchor can not the problem of recycling, this utility model hollow grouting anchor has simple operation specification, simple and practical feature.
