Hollow injection bar combines drilling,anchoring and grouting

Hollow injection bar combines drilling,grouting,anchoring together.It's not only reliable,efficient and convenient but also suitable for loose soils and fractured zones.Hollow injection bar is mainly used for fractured zones,it can be done in complex ground conditions to prevent a large amount of problems in which rock mass is difficult to dill a hole or full of collapsed boreholes and earth mass with unfinished grounting.It gives a full play to bolting support,and enhanced the loading capacity of surrounding rock,as well as provides a guarantee for the stability and durability of rock mass.

Hollow injection bar combines drilling,grouting,anchoring together.It's not only reliable,efficient and convenient but also suitable for loose soils and fractured zones.Hollow injection bar is mainly used for fractured zones,it can be done in complex ground conditions to prevent a large amount of problems in which rock mass is difficult to dill a hole or full of collapsed boreholes and earth mass with unfinished grounting.It gives a full play to bolting support,and enhanced the loading capacity of surrounding rock,as well as provides a guarantee for the stability and durability of rock mass.

Meanwhile,it also provides good effect for a great many applications.This injection hollow bar is a kind of hollow bar with international full thread ,which consists of anchor head,anchor plate,stop-grouting plug and dedicated rat  --pid grouting joint.It's widely applied in railway,highway,tunneling,mining,hydroelectric station,slope stabolization,dyke,brige base,breakwater,high-rise buildings and frastructure constructions and so on.

I would like to introduce some features of hollow injection bar in the following:

1.Hollow design,realize the functions of grouting.

2.High pressure grouting can be used to reinforce the rod body.

3.Grouting can wrap full length of rod body,pervent corrosion and can be used for permanent support.

4.Easy installation,free of thread processing,convenient installation of anchor plate and anchor nut.
