Abstract
The utility model discloses a kind of reusable anti-collapse aperture apparatus of plate brad supporting, belong to architecture Foundation Pit Engineering field, including section casing, end casing and connecting tube, end casing includes the jacking casing positioned at the blade foot of end casing lower end and positioned at end casing upper end, and blade foot and jacking casing, which are integrally formed, to be arranged.Section casing meets different soil-nail parameter requirements in conjunction with connecting tube；Blade foot is gradually shortened by upside to downside, to reduce resistance, casing is facilitated to be inserted into the soil body.The utility model effectively prevent collapse hole, guarantee soil nailing pore-forming is gone on smoothly, and improves hole quality, reusable suitable for punching drilling soft soil horizon or layer of sand.
Description
Technical field
The utility model relates to building implement fields, and in particular to a kind of reusable anti-collapse hole dress of plate brad supporting
It sets.
Background technique
Plate brad supporting start the 1990s China apply, due to construction is simple flexibly, to structures shadow around
The advantages that sound is small, cheap, and construction speed is fast is widely used.But in soft soil horizon or layer of sand, soil nailing pore-forming
It is easy collapse hole, to influence construction speed and construction quality.Therefore, in order to develop the underground space, guarantee base pit engineering safety, grind
Studying carefully prevents plate brad supporting collapse hole device from having great importance.
Currently, there are mainly two types of modes for the anti-collapse hole measure of plate brad supporting engineering: first is that control rate of penetration；Second is that using
Mud armlet.The former is only applicable to the higher layer of sand area of compactness, smaller scope of application, and is difficult to control；The latter needs existing
Field prepares mud, increases construction complexity, and later period mud eliminating is not clean, it will causes slip casting to be interrupted, influences soil nailing and cohere
Power is not easy to guarantee construction quality.
Utility model content
The purpose of the utility model is to provide a kind of easy for construction, reuses, cheap, convenient for control soil nailing branch
Protect anti-collapse aperture apparatus.
The purpose of this utility model is achieved through the following technical solutions:
A kind of anti-collapse aperture apparatus of reusable plate brad supporting, it is characterised in that: it includes section casing, end casing and company
Adapter tube, the end casing include positioned at end casing lower end blade foot and positioned at end casing upper end jacking casing, the blade foot with
Jacking casing is integrally formed setting.
It is further improved as the utility model, described section of casing is steel pipe, and both ends are respectively provided with internal screw thread, section casing
Internal diameter with connection bore it is identical.Section casing length is 2 meters, and it is long to can satisfy different soil nailings by the connection of multiple sections of casings
The requirement of degree.
It further being improved as the utility model, jacking casing is steel pipe, and internal screw thread is arranged in one end far from blade foot,
The internal diameter of jacking casing and connection are identical to silk internal diameter, to connect with section casing；The oblique section that blade foot section is 45 °, upper length
Under it is short, be conducive to reduce resistance, facilitate jacking.
It is further improved as the utility model, the connecting tube is steel material, and both ends are respectively provided with and section casing, top
The external screw thread to match into the internal screw thread on casing, the internal diameter of connecting tube is identical as section casing, end casing internal diameter, can effectively by
It is connected as an entirety.
The utility model is easy for construction, reuse, is cheap, can effectively prevent soil nailing pore forming process convenient for control
In there is collapse hole.Specifically have the following beneficial effects:
1, since the section casing of the device can make multiple, it can satisfy the requirement of different soil-nail parameters, while can be with
It reuses.
2, by the way that blade foot is arranged on the casing of end, resistance can be effectively reduced, casing is made smoothly to be inserted into the soil body.
Detailed description of the invention
Fig. 1 is the using state structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model.
In figure, 1 is section casing；2 be end casing, and 2-1 is blade foot, and 2-2 is jacking casing, and 3 be connecting tube, and 4 be sandy soils,
5 be armature boring machine.
Specific embodiment
Further details of explanation and illustration is made to the utility model below in conjunction with the drawings and specific embodiments.It should be noted that
, following embodiment is only the preferred embodiment of the utility model, rather than whole embodiments, should not be caused practical new to this
The limitation of type protection scope.On the basis of the utility model, that makes any not creative repairs those skilled in the art
Change or replace, is regarded as falling into the protection scope of the utility model.
Embodiment 1
The anti-collapse aperture apparatus of plate brad supporting of embodiment 1 as shown in Figure 2, including section casing 1, end casing 2 and connecting tube 3,
The end casing 2 includes the jacking casing 2-2 positioned at the blade foot 2-1 of end 2 lower end of casing and positioned at end 2 upper end of casing, the sword
Foot 2-1 and jacking casing 2-2, which is integrally formed, to be arranged.Described section of casing 1 is steel pipe, and both ends are respectively provided with internal screw thread, described section of shield
1 internal diameter of cylinder is identical as 3 internal diameter of connecting tube.Section casing length is 2 meters, can satisfy different soil nailings by the connection of multiple sections of casings
The requirement of length.
The jacking casing 2-2 is steel pipe, one end setting internal screw thread far from blade foot 2-1, in the jacking casing 2-2
Diameter is identical as 3 internal diameter of connecting tube, to connect with section casing 1.The section the blade foot 2-1 is 45 ° of inclined surface, short under upper length, is had
Conducive to resistance is reduced, facilitate jacking.
The connecting tube 3 is steel material, and both ends are respectively provided with to match with the internal screw thread on section casing 1, jacking casing 2-2
External screw thread, the internal diameter of connecting tube 3 is identical as section casing 1, jacking casing 2-2 internal diameter, can effectively connect it as one it is whole
Body.
Use example
As shown in Figure 1, predetermined soil nailing position in sandy soils 4 is pressed into end casing 2, make the long end of blade foot 2-1 in upside,
Then armature boring machine 5 gradually pierces, and as drilling increases, 3 one end of connecting tube is connected with end casing 2 by internal and external threads,
3 other end of connecting tube is connected with section casing 1 by internal and external threads.As the growth of drilling repeats to connect connecting tube 3 and section casing 1
It connects, until drilling depth reaches design requirement.Armature boring machine is withdrawn from after the completion of drilling, is inserted into soil nailing, and gradually removes section shield
Cylinder 1, connecting tube 3 and end casing 2, subsequent concrete perfusion complete plate brad supporting.
