Abstract
The utility model relates to a collapse preventing hole enlarger for drilling through soft stratum by a horizontal directional drill, which comprises a drill stem and a body case, wherein the front part of the body case is a cutting section which is a conical surface. The cutting section is distributed with cutting teeth and mud spouts. The utility model is characterized in that the middle part of the body case is a squeezing and enlarging section which is a cylindrical section connected with the bottom of the conical surface of the cutting section and the rear part of the body case is a smearing section which is a cylindrical section connected with the squeezing and enlarging section. The outside diameter of the squeezing and enlarging section is larger than the outside diameter of the smearing section, the mud spouts on the cutting section is parallel to the drill stem and the rear end of the body case is provided with mud spouts. The utility model is mainly suitable for crossing the soft stratum by the horizontal directional drill, and has the advantages that a hole wall can be strengthened and kept in good condition and crossing pipelines can smoothly penetrates through the hole.
Description
Technical field
The utility model relates to a kind of reamer, and particularly a kind of horizontal directional drill passes through broken ground with preventing the landslide reamer.
Background technology
At present in the horizontal directional drill crossing construction, selecting suitable reamer according to geologic structure is the engineering key of success, and the structure of reamer and size are key factors, normally used reamer mostly relatively is fit to harder geological conditions, and when passing through on some softer stratum, use these traditional reamers,, be unfavorable for the success of passing through because the quality of pore-forming is not good.
Summary of the invention
The purpose of this utility model provides a kind of horizontal directional drill and passes through broken ground with preventing the landslide reamer, solved the mostly relatively more suitable harder geological conditions of reamer in the prior art, and when passing through on some softer stratum, the quality of pore-forming is not good, is unfavorable for the problem of passing through.The utility model design level orientation drills the anti-landslide reamer of broken ground more, the front portion that comprises drilling rod, housing is a segment of cutting, segment of cutting is a conical surface, be distributed with cutting teeth and mud nozzle on the segment of cutting, it is characterized in that: the middle part of housing is squeezed section, squeezed section is a cylindrical section that is connected with segment of cutting conical surface bottom, the rear portion of housing is a smearing compacted section, smearing compacted section be one with squeezed section cylindrical section that is connected, squeezed section external diameter is greater than smearing compacted section, mud nozzle on the segment of cutting is parallel with drilling rod, and the rear end of housing is provided with mud nozzle.The utility model has the advantages that and to play the reinforcement reinforcement effect to hole wall, guarantee the intact of hole wall, the pipeline that passes through can be passed from the hole smoothly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise drilling rod 1 among the figure, the front portion of housing 2 is a segment of cutting 3, segment of cutting 3 is a conical surface, be distributed with cutting teeth 4 and mud nozzle 5 on the segment of cutting 3, it is characterized in that: the middle part of housing 2 is squeezed section 6, squeezed section 6 is a cylindrical section that is connected with segment of cutting 3 conical surfaces bottom, the rear portion of housing 2 is a smearing compacted section 7, smearing compacted section 7 be one with squeezed section 6 cylindrical section that is connected, squeezed section 6 external diameter is greater than smearing compacted section 7, and squeezed section 6 external diameter is bigger, plays the effect in squeezed duct, the external diameter of smearing compacted section 7 is less, play steady hole and smear real hole wall, the mud nozzle 5 on the segment of cutting 3 is parallel with drilling rod 1, and having reduced forming is the destruction of hole wall, the rear end of housing 2 is provided with mud nozzle 8, increased the speed of mud flow, be beneficial to the earth in the hole carry portal outside, reduced the pulling force in time hauling pipe road simultaneously.Adopted said structure, made reamer play the reinforcement reinforcement effect, guaranteed the intact of hole wall, the pipeline that passes through can be passed from the hole smoothly hole wall.
Claims (3)
