Description
Technical field
The application relates to the equipment of bore operation in a kind of civil engineering, particularly relates to a kind of protecting for bore operation
Cylinder.
Background technology
Rotary digging drilling hole is the form of construction work of pore-forming operation in a kind of applicable building foundation engineering, is primarily adapted for sand, viscosity
The soil layer constructions such as soil, slity soil, in the multiple foundation basic constructions such as bored concrete pile, diaphragm wall, strengthening of foundation.Casing is in boring
During filling pile construction, affect construction speed and salvo that is safe and that take for preventing hole wall collapse hole near aperture.
Stable hole wall can be played, prevent the hole that collapses, it is also possible to isolation surface water, starter, spud pile position, wait effect.Due to geology bar
The complexity of part, when there is mud for pile foundation bottom, the mud moulding shape in drilling process in stream can be constantly to hole
Inside subside and be difficult to pore-forming, and ground local subsidence can be caused, jeopardize rig, neighbouring building structure and underground utilities safety.
There is the situation of mud for this pile foundation bottom, existing settling mode is to bury long casing underground, makes casing pass through
Wear whole mud, thus avoid mud to subside in hole, and can effectively prevent ground local subsidence and the harm brought thereof.So
And, the construction method of the whole mud in pile foundation bottom is run through for burying long casing underground, if mud is distributed shallower in bottom, long
Casing can effectively solve the construction difficult problem brought because of mud.But be distributed relatively deep in the earth formation for mud, top exists relatively
The situation of thick soil stratum, runs through the way of whole mud according to conventional long casing, because casing length is oversize, except casing needs customization
Outward, overlength casing also will bring and bury and extract difficulty underground, and affect the normal construction of rotary drilling rig.

The casing for bore operation given by this utility model, by burying outer casing, bottom underground in upper end, hole
Bury interior casing underground, the cohesive strength of casing can be decomposed on two casings by soil layer, facilitate shield-tube embedment and extract, reduce construction
Difficulty.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment one；
Fig. 2 is the structural representation of this utility model embodiment two.
Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the application is described in further detail.
Embodiment one:
The casing for bore operation given by the present embodiment, as it is shown in figure 1, include for being embedded in outside upper end, hole
Casing 1, and for being embedded in the interior casing 2 of bottom, hole.Wherein, the internal diameter of outer casing 1 is more than the external diameter of interior casing 2 so that
Outer casing 1 is enclosed within the outside of interior casing 2.For guaranteeing that interior casing 2 passes through outer casing 1, outer casing 1 and interior casing can not be made again
Excesssive gap between 2, in the present embodiment, the internal diameter of outer casing 1 is at least than the big 50cm of external diameter of interior casing 2.When boring machine drill
After the pre-buried degree of depth of exit orifice, by outer casing 1 press-in hole, should ensure that casing center and pile center deviation must not be big in the process
In 0.05m.Continue boring by drill bit again, after being drilled into the interior pre-buried degree of depth of casing 2, interior casing 2 is pressed in hole.Construct
Bi Hou, it is ensured that outer casing 1 and interior casing 2 upper end above ground level 0.20～0.50m.
Casing given by the present embodiment is applicable to the hole depth operation less than interior casing 2 length, due to the upper end soil in hole
Layer contacts with outer casing 1 surface, and bottom contacts with interior casing 2 surface so that soil layer decomposes two to the cohesive strength of casing
On casing, thus reduce the frictional force between single casing and soil layer, it is simple to the embedment of casing with extract.
Embodiment two:
The present embodiment is to be improved on the basis of embodiment one, and the present embodiment is mainly relatively big in drilling depth, single protects
In the case of tube length degree cannot meet, interior casing 2 and outer casing 1 are coupled together use.Specifically, as in figure 2 it is shown, this enforcement
In example, the top of interior casing 2 sets locking mechanism, and this locking mechanism is at least two snap close 21, the top of outer casing 1 be provided with
The fixing device 11 of correspondence.Snap close 21 is used for being connected with outer casing 1 by interior casing 2 by flexible piece with fixing device 11
Come.Wherein, flexible piece 3 is the rope of bent curling, can be steel wire rope 3, it is, of course, also possible to be chain etc..
In the present embodiment, the method for embedding of outer casing 1 is same as in Example 1, and its difference is, buries interior casing 2 underground
Time, first steel wire rope 3 one end is fixed on the snap close 21 of interior casing 2 upper end, is then pressed into interior casing 2, when interior casing 2 reaches
Behind precalculated position, the other end of steel wire rope 3 is fixed in the fixing device 11 of outer casing 1.For guaranteeing safety, protect in should ensure that
Cylinder 2 top end faces are higher than the mud in hole, and should exceed outer casing 2 more than bottom end face 1m, i.e. connect outer casing 1 top
And the steel wire rope 3 between interior casing 2 top is smaller than the length of outer casing 1, and both length at least differ 1m.So, mud
Both will not cover interior casing 2 to be flowed between interior casing 2 and outer casing 1, also will not protect in causing due to the ductility of steel wire rope 3
Cylinder 2 sinks down into outside the bottom of outer casing 1, it is ensured that interior casing 2 can be extracted after grouting smoothly.
The casing for bore operation given by this utility model, by burying outer casing, bottom underground in upper end, hole
Bury interior casing underground, the cohesive strength of casing can be decomposed on two casings by soil layer, facilitate shield-tube embedment and extract, reduce construction
Difficulty.
Above content is to combine the further description that the application is made by specific embodiment, it is impossible to assert this Shen
Being embodied as please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off
On the premise of the present application is conceived, it is also possible to make some simple deduction or replace.
