Description
Technical field
A kind of water conservancy beach slip casting drilling rod guide sleeve of the utility model is related to a kind of pair of shoal area and carries out inlet well
When, to the guide sleeve that drilling rod is oriented to, belong to water conservancy construction field.In particular to a kind of to squeeze into beach in advance, by solid
The guide sleeve being oriented to drilling rod is covered calmly.
Background technique
Currently, carrying out drilling injection slurries in water conservancy casing pipe protection, forming foundation pile and be used for engineering construction, leaning on
The regions such as beach, the wetland in nearly waters, more difficult when needing to drill, since soil property water content is high, drill hole inner wall molding is poor,
Drilling is easy to be filled by mud, and since the mobility of mud is strong, also very poor to the guiding role of drilling rod, so that drilling
It position and needs to differ larger, accurate support cannot be provided for subsequent foundation pile, it is existing to carry out constructing foundation pile
Steel mesh is squeezed into for outer ring, but this method needs biggish external force, and the problem of internal mud still has drilling, it cannot
Solve the problems, such as drilling rod in the guiding of shoal area.
Summary of the invention
In order to improve above situation, a kind of water conservancy beach slip casting drilling rod guide sleeve of the utility model provides one kind and beats in advance
Enter in beach, the guide sleeve that drilling rod is oriented to by fixing sleeve.It can be improved to beach surface drilling effect.
A kind of water conservancy beach slip casting drilling rod guide sleeve of the utility model is achieved in that a kind of water conservancy beach of the utility model
Slip casting drilling rod guide sleeve is applied to be made of pressurized ring, internal screw thread, fixing sleeve, insertion item, retraction slot, expansion slot and drag ring, it is described
Fixing sleeve is cylindrical hollow structure, and fixing sleeve diameter passes through and is gradually reduced, and pressurized ring one is placed on fixing sleeve
On one end, the pressurized ring internal diameter and fixing sleeve one end inner diameter size are equal, and the pressurized ring inner sidewall is equipped with internal screw thread, multiple
Drag ring is respectively placed in pressurized ring side, and equiangularly arranged between drag ring, and two expansions are equidistantly provided on the fixing sleeve
It is connected inside slot, the expansion slot and fixing sleeve, and expansion slot one end extends downward into the fixing sleeve other end, two insertion items
It being symmetrically placed on the outside of fixing sleeve, the insertion item is located between two expansion slots, two groups of retraction slots are provided on the fixing sleeve, and
Corresponding with two insertion items respectively, every group of retraction slot is made of at least five retraction slots, and corresponding insertion item is divided into
Multistage.
In use, drilling rod is connected by internal screw thread with pressurized ring first when drilling to regions such as beach, wetlands
It connects, the utility model is then placed in perforated area surface, so that electric drill is driven drilling rod rotation, and gradually push away drilling rod down, bore
Bar drives the utility model unitary rotation and moves down, and then gradually pierces fixing sleeve inside beach, when fixing sleeve is complete
After squeezing into beach inside, pressurized ring is pressed in beach surface, and drag ring is contacted with beach surface, increases between pressurized ring and beach surface
Frictional force, at this point, pressurized ring is fixed, drilling rod is moved down along pressurized ring, and then drilling rod is gradually moved into fixing sleeve
Dynamic, fixing sleeve is oriented to drilling rod, and with constantly moving down for drilling rod, under drilling rod extruding, expansion slot expansion, retraction slot is received
Contracting, is embedded in item and drill hole inner wall is in contact, and increases the frictional force between the wall of a borehole, reaches and carries out inlet well to shoal area
When, purpose that drilling rod is oriented to.
Beneficial effect.
One, structure is simple, convenient and practical.
Two, the influence of mud when can reduce drilling.
Three, it can be improved to beach surface drilling effect.
Detailed description of the invention
Fig. 1 is a kind of three-dimensional structure diagram of water conservancy beach slip casting drilling rod guide sleeve of the utility model.
Fig. 2 is a kind of bottom view of water conservancy beach slip casting drilling rod guide sleeve pressurized ring of the utility model, is only shown
Relationship between pressurized ring and drag ring.
In attached drawing
Wherein part are as follows: pressurized ring (1), internal screw thread (2), fixing sleeve (3) are embedded in item (4), retraction slot (5), expansion slot
(6), drag ring (7).
Specific embodiment:
A kind of water conservancy beach slip casting drilling rod guide sleeve of the utility model is achieved in that by pressurized ring (1), internal screw thread
(2), fixing sleeve (3), insertion item (4), retraction slot (5), expansion slot (6) and drag ring (7) composition, the fixing sleeve (3) are column
Shape hollow structure, and fixing sleeve (3) diameter passes through and is gradually reduced, pressurized ring (1) one is placed on fixing sleeve (3) one
On end, pressurized ring (1) internal diameter and fixing sleeve (3) one end inner diameter size are equal, and pressurized ring (1) inner sidewall is equipped with interior spiral shell
Line (2), multiple drag rings (7) are respectively placed in pressurized ring (1) side, and equiangularly arranged between drag ring (7), the fixing sleeve
(3) it is equidistantly provided with two expansion slots (6) on, is connected inside the expansion slot (6) and fixing sleeve (3), and expansion slot (6) one end
Fixing sleeve (3) other end is extended downward into, two insertion items (4) are symmetrically placed on the outside of fixing sleeve (3), insertion item (4) position
