Description
Technical field
The present invention relates to backfill foundation pit or slope reinforcement fields, convert attachment device with drill bit more particularly to one kind
Pierce formula steel tube for soil-nail.
Background technique
Soil nail wall is a kind of soil body reinforcement technology in situ, and excavation slope is added reinforcing bar soil nailing made of reinforcing bar
Gu.According to site requirements, us is needed to carry out a large amount of backfill processing to pre-existing topography, meanwhile, because of complicated composition of banketing, unevenness
It is even, lead to the disadvantages of density is insufficient, intensity is low, soil nailing pore-forming is difficult, the stability and soil nailing of welding with filler wire soil-nail wall support are applied
Work is always a great problem of geotechnical slope supporting, and currently used backfill side slope soil nailing is driven into soil using common steel tube soil nailing
Body, then carry out injecting treatment.But it is often had the disadvantage in that in work progress
(1) in work progress, locally there is soil compaction in backfill, and it is big that steel tube for soil-nail squeezes into soil body difficulty；
(2) common steel tube soil nailing is low with soil body anchoring strength, unbalance stress, causes stability of soil nailed wall poor.
Summary of the invention
Formula steel pipe soil is pierced with drill bit conversion attachment device technical problem to be solved by the invention is to provide a kind of
Nail solves backfill in work progress and soil compaction locally occurs, and it is big that steel tube for soil-nail squeezes into soil body difficulty, common steel tube soil nailing and the soil body
Anchoring strength is low, unbalance stress and lead to the problem of stability of soil nailed wall difference, to increase backfill side slope steel tube for soil-nail supporting
Structural stability shortens the construction period, save the cost.
The technical solution adopted by the present invention to solve the technical problems is: providing a kind of with drill bit conversion attachment device
Formula steel tube for soil-nail, including soil nailing main body are pierced, described soil nailing main body one end is point, and the other end is axially connected with conversion and connects
Connection device, is twist disposed with screw wing on the lateral wall of the soil nailing main body, the soil nailing body interior it is hollow and
Injected hole is uniformly provided on side wall, the conversion attachment device includes the internal threaded nut column and internal threaded nut column of one end
The axially extending connecting column in one end, the lateral wall two sides of the connecting column are symmetrically arranged side by side with a pair of of shear key, described
It is axially provided with slot on one end two sides side wall of soil nailing main body, one end of the slot and on both sides of the middle symmetric transverse is provided with and shearing resistance
The lateral slot that key matches.
As a supplement to the technical solution of the present invention, on the lateral wall of the soil nailing main body with injected hole
Corresponding position is equipped with hangnail angle steel.
The utility model has the advantages that piercing formula steel tube for soil-nail with drill bit conversion attachment device the present invention relates to a kind of, structure is simple,
New-type steel tube for soil-nail increases screw wing, effectively reduces soil body resistance in boring procedure, is conducive to steel tube for soil-nail and pierces the soil body, spiral
The wing, which increases, follows closely anchor force with slip casting soil body contact surface, increase steel pipe soil and the soil body；Steel tube for soil-nail is pierced the soil body and is converted using drill bit
Attachment device can guarantee steel tube for soil-nail angle of penetration precision by adjusting drilling machine, improve steel tube for soil-nail construction quality；Every steel pipe
Nail Construction is completed, and drill bit conversion attachment device is removed, and recycling saves cost.

Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in Figs 1-4, embodiments of the present invention are related to a kind of piercing formula steel pipe with drill bit conversion attachment device
Soil nailing, including soil nailing main body 1, described 1 one end of soil nailing main body are point 4, and the other end is axially connected with conversion attachment device
A is twist disposed with screw wing 3,1 inner hollow of soil nailing main body and side on the lateral wall of the soil nailing main body 1
