Description

Grouting Pipe attachment means for anti-float anchor rod construction
Technical field
This utility model relates to a kind of construction implement, and a kind of Grouting Pipe for anti-float anchor rod construction is even Connection device.
Background technology
Anti-float anchor rod, is the one of architectural engineering underground structure measure of anti float.Existing anti-float anchor rod construction process includes: Preparation of construction → anchor pole making → anchor hole location → pore-forming → clear hole → lower the body of rod → perfusion mortar → place is cleaned, is cut aperture Unnecessary mortar → quality testing.Wherein slip casting process be after pore-forming, take out drilling rod enter reinforcing bar down, the most just utilize note Slurry pipe injects mortar in boring.This technique has following defects that 1) take out drilling rod and need that boring is done retaining wall later and process, Otherwise holing the wall that easily collapses, especially in the sandy soil construction on the ground that soil property is soft, drilling rod has collapsed during taking out wall the most, very Easily causing cannot slip casting;2) when that boring being deeper, the distance of slip casting is remote, mortar poor fluidity, easily causes slip casting uneven Even, affect construction quality;3) complicated construction technique, efficiency is low, long construction period.To this end, I proposes a kind of brand-new anti-floating Anchor rod construction process, after boring completes, by the inner chamber of hollow drill perfusion mortar in boring while proposing drilling rod, Having drilling rod retaining wall during slip casting, it is not necessary to extra retaining wall operation, boring will not be caved in, and mortar is directly entered boring by drilling rod Bottommost, compactness of grouting is high, it is not necessary to tamping operation, will not produce pore, and construction quality is high.To this end, it is hollow except utilizing Beyond drilling rod, also require there is a Grouting Pipe attachment means, Grouting Pipe can be connected to the upper end of hollow drill.
Summary of the invention
The purpose of this utility model be to provide a kind of compact conformation, easy to use, Grouting Pipe is connected to hollow drill Upper end is for the Grouting Pipe attachment means of anti-float anchor rod construction.
For achieving the above object, this utility model is by the following technical solutions:
Grouting Pipe attachment means for anti-float anchor rod construction described in the utility model, including connecting tube, described connecting tube It is fixedly connected on the outer wall of trocar sheath, the inner chamber of described trocar sheath is coaxially installed with interior pipe fitting, the axis of said inner tube part Place is provided with the passage at through two ends, with running through the through hole of sidewall on the sidewall of interior pipe fitting, the external port of described through hole with set The inner port putting connecting tube on outer sleeve inner wall is corresponding;The two ends of interior pipe fitting have been respectively fixedly connected with upper flange, purgation Blue.
The inner port position of described connecting tube is higher than the position of its external port;The external port position height of described through hole is in the inner The position of port.
Being provided with annular groove on the outer wall of interior pipe fitting, the external port of described through hole is positioned in annular groove.
After using technique scheme, this attachment means can be connected to Grouting Pipe the upper end of hollow drill, its structure Compact, easy to use, can significantly shorten construction period, improve construction quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of this utility model.
Detailed description of the invention
As shown in drawings, the Grouting Pipe attachment means for anti-float anchor rod construction described in the utility model includes connecting tube 1, For connecting Grouting Pipe.Connect for convenience and make to be connected firmly, the outer tube wall of the external port of connecting tube 1 is provided with projection Retaining ring, after Grouting Pipe is sleeved in connecting tube 1, retaining ring can increase frictional force between the two, prevents from getting loose.Institute State connecting tube 1 to be fixedly connected on the outer wall of trocar sheath 2, and the inner chamber of connecting tube 1 extend to the inwall of trocar sheath 2, The mortar making connecting tube 1 input can enter the inner chamber of trocar sheath 2.
Being coaxially installed with interior pipe fitting 3 in the inner chamber of described trocar sheath 2, the outline of interior pipe fitting 3 is coupling connecting tube 1 inner chamber Cylindric, make interior pipe fitting 3 can rotate against in connecting tube 1.Through two ends it are provided with at the axis of said inner tube part 3 Passage 4, with running through the through hole 5 of sidewall on the sidewall of interior pipe fitting 3, the external port of described through hole 5 be arranged on trocar sheath 2 inwall On the inner port of connecting tube 1 corresponding, it may be assumed that interior pipe fitting 3 rotates to external port and the connecting tube of through hole 5 when of certain position The inner port docking of 1, the mortar making connecting tube 1 input can be entered by through hole 5 in the passage 4 of interior pipe fitting 3;Interior pipe fitting 3 Two ends have been respectively fixedly connected with upper flange 6, lower flange 7.During use, upper flange 6 and lower flange 7 be respectively used to connect engine and Drilling rod, as it is shown in figure 1, with riffled tube on upper flange 6, and by the output shaft of this riffled tube connection engine, drive Interior pipe fitting 3 rotates;Also with riffled tube on lower flange 7, and connect hollow drill by this riffled tube, pass through female thread Pipe communicating passage 4 and the inner chamber of drilling rod.Certainly, upper flange 6 and lower flange 7 can also connect engine by male-pipe respectively And drilling rod.
The inner port position of described connecting tube 1 is higher than the position of its external port;The external port position of described through hole 5 is higher than it The position of inner port.The external port of connecting tube 1 is downward-sloping can conveniently connect Grouting Pipe, prevents Grouting Pipe from bending, shadow simultaneously The mobility of musical sand slurry;The inner port of through hole 5 is downward-sloping, the mortar in through hole 5 can be facilitated to utilize Gravitational sliding to enter logical In road 4, prevent from blocking through hole 5.
It addition, be provided with annular groove 8 on the outer wall of interior pipe fitting 3, the external port of described through hole 5 is positioned in annular groove 8.Annular groove 8 is made Buffering chamber for being arranged between through hole 5 and connecting tube 1 can improve the connectedness of through hole 5 and connecting tube 1, for mobility relatively Good mortar, even if connecting tube 1 is not alignd with the port of through hole 5, mortar can also enter logical from connecting tube 1 by annular groove 8 Hole 5, to the inner chamber slip casting of drilling rod.
As it is shown in figure 1, for improving sealing property, be provided with sealing between the inwall and the outer wall of interior pipe fitting 3 of trocar sheath 2 Ring 9, two seals ring 9 lays respectively at the upper/lower terminal of interior pipe fitting 3, prevents mortar from passing through between trocar sheath 2 and interior pipe fitting 3 Slot leakage.
During use, the outer wall of trocar sheath 2 welds some hangers 10, this Grouting Pipe attachment means is solid by hangers 10 It is scheduled on the lower end of engine, and the power output shaft of engine is connected with upper flange 6, hollow drill is arranged on lower flange On 7, engine is risen to together with attachment means, drilling rod the upper end of rig floor support.It is then turned on engine boring, boring After arriving desired depth, the height of engine assembly also decreases minimum point, and Grouting Pipe is now installed to connecting tube 1 On, start lifting machine slow lifting power machine assembly, along with the rising of engine assembly, grouting equipment passes through Grouting Pipe sand Slurry injects in hollow drill, until the fully out boring of drilling rod, now grouting with plunger completes the most, the most again by under anti-float anchor rod Enter in the boring of mortar ot-yet-hardened.
