Description

Device for pipe curve drilling passing through stratum

The utility model relates to the mechanical device of a kind of curve boring penetrating ground of buried pipeline construction, belongs to the pipeline construction technology field.

At present, construction technology about buried pipeline has multiple device, bore as orientation, though advanced technology, its operating expenses and equipment occupancy expenses costliness, and for example existing jacking construction, because horizontal jacking needs make working pit at the in-out end of push pipe, drops into a large amount of accessory buildings for this reason, because establishing, the pipeline domestic demand is used for the work decompression storehouse of usefulness of operating personnel simultaneously, and the caliber of jacking is restricted, must be more than 1.6 meters at diameter.

The purpose of this utility model is that the machinery head that provides a kind of utilization to be welded on whole piece crossing pipeline front end directly carries out the new equipment of pilot hole penetrating ground, it is applicable to that various soil properties, chiltern and gravel diameter are no more than 30 millimeters stratum, thereby overcomes the shortcomings and deficiencies of existing buried pipeline penetrate construction technology.

The utility model is that the machinery head is arranged on whole piece crossing pipeline front end, connect reductor drive drilling rod and drill bit with the wet type motor that is contained in the machinery head, the mud fluid column injects hollow drill by the hole on the drilling rod, inject directly on brill sheet front portion from drill rod end, the silt particle that bores is broken up, by boring the hole at sheet rear portion, annular space along the crossing pipeline outer wall takes ground to, the machinery back of head is provided with automatic angle measurement instrument and directional transmitter, the angle of inclination and the deviation of directivity of monitoring crossing pipeline, utilization is located at four piston rods that a machinery splicing position cross is arranged, and waits the stroke synchronous fuel tank, adjusts mechanical brilliance degree.

Advantage of the present utility model is small investment, and the construction period is short, and technical performance is safe and reliable, and the ground ancillary works is simple, is convenient to the fixed point construction.Be applicable to that various soil properties, chiltern and gravel diameter are no more than 30 millimeters stratum.Can arbitrarily adjust the crossing pipeline degree of depth, the buried depth degree reaches 40 meters, and the upper and lower angle of inclination and the deviation of directivity show automatically.
