Abstract
A kind of self-advancing type pipe canopy anchor pole for tunnel weakness geology band country rock pretreatment, including drill bit, drilling rod, described drilling rod is the steel pipe of a hollow, drilling rod wall is provided with multiple injected hole, two ends of drill is equipped with external screw thread, drilling rod front end is spirally connected with drill bit and is connected, and rear end is spirally connected with the drill sleeve of a bit shank adapter.This utility model drilling rod is hollow pipe, after creeping into projected depth, need not move back brill, and directly to drilling rod internal injection, by drilling rod as pipe boron steel pipe, speed of application is fast, simple to operate, high treating effect.
Description
Technical field
This utility model relates to weak geology band country rock pretreatment or sump remedy construction field in constructing tunnel, specifically relates to
And it is a kind of for tunnel weakness geology band country rock or the anchor pole of the pipe canopy of sump remedy.
Background technology
In constructing tunnel, be frequently encountered by weak geology band country rock or landslide, for ensure constructing tunnel make smooth advances and
Ensureing construction safety, weak geology band country rock or landslide paragraph must be processed by job site.The most more conventional process
Mode has advanced tubule pre-pouring grout to process and large-scale lead pipe grouting pretreatment.Advanced tubule pre-pouring grout processes, and is first to exist
Weak geology band wall rock drill-hole, is then inserted into per-fore pouring liquid with small pipe to reinforce country rock in hole.The district that advanced tubule processes
Section is shorter, and typically at 3-5m, and in broken loose media country rock, boring is frequently encountered by hole clipping, collapse hole cannot the problem of inserted link etc.；
Super-front large pipe shed must perform guiding wall in hole, but builds guiding Qiang Jiguanpeng operating room behaviour in hole in the range of small space
Make difficulty big, and be also frequently encountered by the problem that cannot execute drilled as holes in broken loose media country rock, it is necessary to take with plumber's skill is executed
Work, costly.
Summary of the invention
The purpose of this utility model is to provide a kind of self-feeding anchor pile for tunnel weakness geology band country rock, to overcome
The problem that cannot execute drilled as holes in weak geology band or landslide incompact-deposit bodies country rock.
The technical solution of the utility model is as follows:
A kind of self-advancing type pipe canopy anchor pole for tunnel weakness geology band country rock pretreatment, including drill bit, drilling rod, its feature
Being: described drilling rod is the steel pipe of a hollow, drilling rod wall is provided with multiple injected hole, and two ends of drill is equipped with external screw thread, drilling rod
Front end is spirally connected with drill bit and is connected, and rear end is spirally connected with the drill sleeve of a bit shank adapter.
This utility model simple in construction, drilling rod body is hollow pipe, after creeping into projected depth, need not move back brill, directly to brill
Bar internal injection, by drilling rod directly as pipe boron steel pipe, need not install pipe boron steel pipe after first pore-forming, have construction speed in construction
Spend fast, simple to operate, high treating effect, the advantage such as economic and practical, construction speed can be effectively improved, reduce cost, it is to avoid be super
Front ductule processes paragraph bit freezing that is short and that be frequently encountered by broken loose media country rock, the defect of collapse hole, also solves big pipe
Canopy operation easier is big, take with the high difficult problem of pipe process costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is occupation mode schematic diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model includes drill bit 1, drilling rod 2, described drilling rod 2 is the steel pipe of a hollow, on drilling rod wall
Being provided with multiple injected hole 3, drilling rod 2 two ends are equipped with external screw thread, and the front end of drilling rod 2 is spirally connected with drill bit 1 and is connected, rear end and a bit shank
The drill sleeve 4 of adapter is spirally connected.
In use, according to the needs of design drilling depth, drilling rod 2 can be by 2 or the hollow of more than 2 for this utility model
Lengths of steel pipes connects, and two cored steel pipeline sections are spirally connected by setting female sleeve pipe 5.
As in figure 2 it is shown, before pipe roof construction, first install 1 Pin and guide steelframe and open guide-localization on steelframe by design pitch
Hole；Drilling jumbo or handheld pneumatic rock drill 6 are connected with the bit shank 7 of bit shank adapter of the present utility model, drill bit and steel
Frame pilot hole centering is also adjusted and is executed brill angle, starts to creep into by the degree of depth, the angle of design.In drilling process, when drilling rod 2 length
When not reaching design drilling depth, back out bit shank adapter, reconnect one section of cored steel pipeline section with extension arm by sleeve pipe 5,
Then connect bit shank adapter to continue to execute drilling to completion with rig.After having crept into, back out bit shank adapter, after drilling rod
End connects grouting pipe and slip casting machine, carries out grouting and reinforcing rock mass, and hollow drill pipe, need not be additionally mounted directly as pipe boron steel pipe
Pipe boron steel pipe.
Claims (2)
1., for a self-advancing type pipe canopy anchor pole for tunnel weakness geology band country rock pretreatment, including drill bit, drilling rod, its feature exists
