Description
Technical field
This utility model is related to a kind of full-rotating drill steel thimble, especially a kind of full-rotating drill steel with porus excretoriuses
Sleeve pipe.
Background technology
Obstacle pile is pulled out construction and is typically adopted full-rotating drill, and full circle swinging driving means clamping steel thimble carries out 360 ° of revolutions
Drilling, steel thimble pushes underground layer in the collective effect of pressure and moment of torsion.Then utilize the retaining wall effect of steel thimble, in steel thimble
Inside carry out pile pulling to remove obstacles.
First section steel bushing pipe racks alloy cutter head, if meet while drilling can cut to it compared with sound-hard obstacle, cutting
Implementation barrier stake afterwards is separated with surrounding soil, reduces the frictional force of obstacle pile and the soil body, and then reduces pulling force during pile pulling,
Adopt wedge type hammer (also known as: drill rod, grip force rod, inverted triangle hammer) concrete-pile in sleeve pipe to be carried out crush inside steel thimble,
Twist off, then remove the soil body and pile body residue in steel thimble with punching grab bucket, until removing to design requirement depth.Finally in time to set
In pipe, water filling keeps water level and the outer pressure-bearing water balance of pipe in pipe, then backfills soil cement, pulls out steel thimble while backfill section by section.
Water is filled, so during backfill soil cement, mud water level constantly rises spilling in steel thimble in invar sleeve pipe
Steel thimble, flows to full-rotating drill and surrounding contaminated sites outside pipe.
Utility model content
Utility model purpose: provide and a kind of convenient arrive outside pipe slime water water conservancy diversion in steel thimble to prevent contaminated sites around
Full-rotating drill steel thimble.
Technical scheme: the full-rotating drill steel thimble with porus excretoriuses described in the utility model, including steel thimble, excretion steel
Pipe and plastic flexible pipe；At least provided with two porus excretoriuses connecting with inside on the side wall of steel thimble；It is provided with excretion in the hole
Female thread is installed, is provided with one end of excretion steel pipe and the installation external screw thread of screw-internal thread fit is installed；Plastic flexible pipe abutting joint
On the other end of excretion steel pipe.
Discharged using the specification that porus excretoriuses, excretion steel pipe and plastic flexible pipe realize slime water in steel thimble, prevent from overflowing
To outside manage by full-rotating drill and surrounding contaminated sites；Can displacement input as needed be made using the setting of multiple porus excretoriuses
With.
As further limits scheme of the present utility model, two porus excretoriuses are provided with steel bushing tube side wall, and two rows
Let out hole to be arranged on the differing heights of steel bushing tube side wall.Can be according to slime water in steel thimble using the setting of porus excretoriuses differing heights
Position selects to use.
As further limits scheme of the present utility model, also include an interior hexagonal envelope for blocking unnecessary porus excretoriuses
Stifled screw.Using interior hexagonal closure screw idle unnecessary porus excretoriuses can be blocked, prevent slime water directly from
Porus excretoriuses overflow.
Compared with prior art, its advantage is this utility model: (1) adopts porus excretoriuses, excretion steel pipe and plastics
The specification that slime water in steel thimble realized by flexible pipe is discharged, and prevents from being spilled over to full-rotating drill and surrounding contaminated sites outside pipe；(2)
Can displacement as needed be come into operation using the setting of multiple porus excretoriuses.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view at a-a in Fig. 1.
In figure: 1, steel thimble, 2, porus excretoriuses, 3, excretion steel pipe, 4, plastic flexible pipe, 5, female thread is installed, 6, outer spiral shell is installed
Stricture of vagina, 7, interior hexagonal closure screw.
Specific embodiment
Below in conjunction with the accompanying drawings technical solutions of the utility model are described in detail, but protection domain of the present utility model
It is not limited to described embodiment.
Embodiment 1:
As illustrated in fig. 1 and 2, the full-rotating drill steel thimble with porus excretoriuses of the present utility model includes: steel thimble 1, excretion
Steel pipe 3 and plastic flexible pipe 4；At least provided with two porus excretoriuses 2 connecting with inside on the side wall of steel thimble 1；In porus excretoriuses 2
Inside it is provided with installation female thread 5, be provided with one end of excretion steel pipe 3 and the installation external screw thread 6 of female thread 5 cooperation is installed；Plastics are soft
Pipe 4 abutting joint is on the other end of excretion steel pipe 3；As preferred version of the present utility model, steel thimble 1 side wall is provided with
Two porus excretoriuses 2, and two porus excretoriuses 2 are arranged on the differing heights of steel thimble 1 side wall；Also include one be used for blocking unnecessary
The interior hexagonal of porus excretoriuses 2 blocks screw 7 and an inner hexagon spanner blocking screw 7 for installing or removing interior hexagonal.
Full-rotating drill steel thimble with porus excretoriuses of the present utility model is when using, if needing to arrange on steel thimble 1
Dry porus excretoriuses 2, at ordinary times or block screw 7 with interior hexagonal when idle and seal, prepare will be fitted with inner hexagon spanner in advance during backfill
When the interior hexagonal closure screw 7 of position unloads, load onto and drain steel pipe 3, then connect the plastic flexible pipe 4 of certain length, in backfill water
During soil, mud emits and flows out through porus excretoriuses 2, by plastic flexible pipe 4 by mud emission to specified location.
When carrying out stake and pulling out, pile top needs water filling in steel thimble 1 immediately after pulling out, be filled to underground bearing water position high
Degree, keep steel thimble 1 inside and outside water level balance, prevent steel thimble 1 surrounding water and soil from extruding into steel thimble 1, lead to surrounding soil,
The sedimentation of underground structure；Before preparing backfill soil cement, first with inner hexagon spanner, the interior hexagonal of appropriate location is blocked screw 7
Unload, load onto excretion steel pipe 3, then the plastic flexible pipe 4 connecting certain length；When being backfilled, mix using the 7% of live mixing
The soil cement of amount is backfilled, and in backfill with block stamp compacting it is ensured that backfill quality, prevents from later three axial trough walls are reinforced and ground
Even wall construction impacts, and the mud above emitting flows out through porus excretoriuses 2, is drained to specified location by plastic flexible pipe 4；Etc. backfill
Stablize closely knit after, started to pull out steel thimble 1, kept soil plug thickness in steel thimble 1 to be not less than 3m, rise and pull out speed controlling in 0.5m/
min；Being circulated with this and carry out, until extracting final section steel thimble 1, being finally backfilled to terrace absolute altitude；After often section steel thimble 1 is extracted
Unload excretion steel pipe 3 and plastic flexible pipe 4 immediately, then with clear water, steel thimble 1 is carried out, blocked with interior hexagonal after cleaning up
Porus excretoriuses 2 are sealed by screw 7.
Although as described above, having represented with reference to specific preferred embodiment and having described this utility model, it must not
It is construed to the restriction to this utility model itself.In the spirit and scope of the present utility model defining without departing from claims
