Abstract
The utility model discloses a jacking device for a small conduit used for grouting for a tunnel. The jacking device comprises a pipe jacking device, an air drill rod and an air drill and is characterized in that the air drill rod is arranged at the front part of the pipe jacking device, the air drill is arranged at the tail end of the air drill rod, so that the force can be transferred uniformly and stably so as not to damage the small conduit, and the pipe jacking device is formed by machining round steel. Compared with the traditional method, the jacking device can save 1/3-1/2 of the process time and has wide application value in the jacking construction for the small conduit in the sand non-stratified rock stratum tunnel.
Description
Technical field
The utility model relates to a kind of ductule jacking mechanism, relates in particular to a kind of tunnel grouting ductule jacking mechanism.
Background technology
Conventional practice is air drill to be bored pricker directly withstand on the ductule termination and head into the stratum, thereby causes the ductule termination to damage and distortion, and ductule can't normally be connected with the slip casting connecting line when slip casting, reduction slip casting work efficiency.Grouting with small pipe is the auxiliary worker's method of tunnel construction commonly used; But when conventional grouting with small pipe adopts air drill to head into, cause the mouth of pipe to damage and distortion, thereby the sealing of the mouth of pipe when influencing slip casting owing to head into the improper meeting of device; Make grouting pressure can not reach purpose of design, thereby influence slip casting effect.
The utility model content
The utility model technical problem to be solved is: to the defective of prior art a kind of installation, dismounting, tunnel grouting ductule jacking mechanism easy to use are provided.
For solving the problems of the technologies described above; The technical scheme of the utility model is: tunnel grouting ductule jacking mechanism, comprise conduit jacking, and air drill bores pricker; Air drill; It is characterized in that air drill bores the front portion that pricker is arranged on conduit jacking, air drill is arranged on the end that air drill bores pricker, thereby reach evenly being unlikely with stable transmission of power ductule is damaged.
Said conduit jacking is to utilize round steel to process.
The ductule mouth of pipe belongs to thin-wall steel tube; Easy deformation under the high-frequency surge effect of air drill; Be converted into relative uniform pressure for reaching air drill high-frequency surge; Thereby preventing mouth of pipe distortion, is to bore at the air drill front end an excessive load transfer device is installed between pricker and the air drill from thinking therefore, and this device can convert high-frequency impact force into low frequency pressure relatively uniformly through this device.
The beneficial features of the utility model is: the comparable conventional method in the past of push pipe is practiced thrift 1/2nd to 1/3rd activity time, heads in the construction at the non-diagenesis formation tunnel of sand ductule to have a wide range of applications.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further;
Fig. 1 is the structural representation of the utility model tunnel grouting ductule jacking mechanism;
Fig. 2 is that the utility model air drill bores the pricker sketch map;
Fig. 3 is the utility model conduit jacking sketch map;
Fig. 4 is the utility model air drill sketch map;
Among the figure, 1, conduit jacking, 2, air drill bores pricker, 3, air drill.
The specific embodiment
As shown in the figure, tunnel grouting ductule jacking mechanism comprises conduit jacking 1; Air drill bores pricker 2, air drill 3, and air drill bores the front portion that pricker 2 is arranged on conduit jacking 1; Air drill 3 is arranged on the end that air drill bores pricker 2, thereby reach evenly being unlikely with stable transmission of power ductule is damaged.Said conduit jacking 1 is to utilize round steel to process; The ductule mouth of pipe belongs to thin-wall steel tube; Easy deformation under the high-frequency surge effect of air drill is converted into relative uniform pressure for reaching air drill high-frequency surge, thereby prevents mouth of pipe distortion; Therefore be to bore at the air drill front end an excessive load transfer device is installed between pricker and the air drill from thinking, this device can convert high-frequency impact force into low frequency pressure relatively uniformly through this device.
