Description
Technical field
The utility model relates to the grouted density nondestructive testing arrangement of a kind of bending anchor pole or anchor pile, is applicable to the thick and nondestructive testing while needing shank portion to bend up of bolt diameter in anchor pole or anchor pile.
Background technology
In general, the grouted density of grouting rock bolt or anchor pile can adopt Acoustic Reflection Method to carry out nondestructive testing." anchor bar quality nondestructive testing technique code " requirement in specification such as (JGJ/T182), termination point of anchor rod should expose, exposed rod should with interior anchor bar body linearly, and revealed section is unsuitable long.If this is to consider to expose after anchor pole bending, can make detection signal become very complicated, the reflected signal of bending anchor pole can disturb useful signal, and the identification, judgement and the leverage reflected energy that affect useful signal are analyzed.
Clear and definite regulation in above-mentioned code: occur one of following situations, Detection of Bolt Bonding Integrity is judged and should be carried out in conjunction with other detection methods: expose that free segment is long, bending or body of rod cross section changeable.
The anchor pile using in engineering is generally made up of 2 ~ 4 anchor poles, and every bolt diameter, in 20mm ~ 36mm scope, also has some bolt diameters more than 20mm.These anchor poles or anchor pile need part to bend up (being connected, being increased in concrete anchorage length etc. as bent up with surface layer structure reinforcing bar) for various reasons.Because reinforcing bar is thicker, all need bend up according to designing requirement part in reinforcement yard, install at the scene that is then transported to.The problem of doing is like this that, after anchor pole or anchor pile part bend up, its grouted density cannot utilize the method for nondestructive testing accurately to judge.If bend up again anchor pole after installing at the scene, because it is thicker, implement comparatively difficulty.
Carry out grouted density detection for bending anchor pole or anchor pile, how to consider to adopt the not only method of convenient but also simple possible, make its engineering demands, be grouting rock bolt or anchor pile construction with quality examination in an important technology.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of not only convenient but also the bending anchor pole of simple possible or the grouted density nondestructive testing arrangement of anchor pile, make its engineering demands.
The technical scheme that the utility model adopts is: the grouted density nondestructive testing arrangement of a kind of bending anchor pole or anchor pile, there is anchor pole or anchor pile that 2 ~ 4 diameters detect at the needs of 20 ~ 36mm, described anchor pole or the bending of anchor pile one end and vertically end insert in anchor hole, anchor hole is interior by being located in the Grouting Pipe injected water cement mortar in the middle of anchor pole or anchor pile, anchor hole aperture section is sealed by quick-setting mortar, it is characterized in that: an isometric reinforcing bar is also vertically implanted in the centre of described anchor pole or anchor pile.
The diameter of described reinforcing bar is 6 ~ 8mm, and reinforcing bar upper end flushes with anchor hole aperture or slightly exceeds aperture.
The anchor pole at described anchor hole top or anchor pile and reinforcing bar cover with layer of concrete.
Described anchor pole or anchor pile are by reinforced steel bar ring radial constraint.
The beneficial effects of the utility model are: in the anchor pole 1, detecting at needs or anchor pile, a reinforcing bar is installed, and simple, solve dexterously anchor pole or anchor pile because bending up the problem that cannot use lossless detection method to carry out grouted density detection.2, this arrangement is identical with ordinary mortar anchor pole for the detection method of bending anchor pole or anchor pile employing, and both have equal levels of precision.3, reserved reinforcing bar, completing after grouted density detection, can bend up or cut off, thereby met structural requirement.
Brief description of the drawings
Fig. 1 is structural layout plan of the present utility model.
Fig. 2 is that the a-a of Fig. 1 is to sectional drawing.
Detailed description of the invention
As shown in Figure 1, 2, the present embodiment has proposed the grouted density nondestructive testing arrangement of a kind of bending anchor pole or anchor pile, has simply solved dexterously anchor pole or anchor pile because bending up without using lossless detection method to carry out the detection of grouted density problem.In the present embodiment, choose tested anchor pole or the anchor pile 2 of 2 ~ 4 diameters at 20-36mm, together with the isometric reinforcing bar 3 that is 6 ~ 8mm with a diameter by it is bound in Grouting Pipe 4 use reinforced steel bar rings 5, wherein, for convenient grouting, Grouting Pipe 4 is located to the centre of anchor pole or anchor pile 2.According to engine request, by one end bending of anchor pole or anchor pile 2, and its vertical end inserts in the anchor hole 8 digging in advance, and by Grouting Pipe 4 toward the interior injected water cement mortar 6 of anchor hole 8, it is fixed.Described anchor hole 8 aperture sections adopt quick-setting mortar 7 to seal, and utilize the reinforcing bar 3 of burying underground to carry out grouted density detection.After detection completes, in order to meet structural requirement, fine steel rib 3 exposed parts can be bent up or cut off.
The anchor pole at described anchor hole 8 tops or anchor pile 2 and reinforcing bar 3 use layer of concrete 1(or shotcrete with mesh layer) cover.
