Description
Technical Field
The utility model relates to a foundation ditch test technical field especially relates to an anti-pulling test frock for foundation ditch soil nail.
Background
The foundation pit is a soil pit excavated at the design position of a foundation according to the elevation of the foundation and the plane size of the foundation, an excavation scheme is determined according to geological and hydrological data and the conditions of buildings nearby the site before excavation, waterproof drainage work is well done, and a side slope can be placed for people who do not excavate deeply, so that the soil slope is stable, and the gradient of the soil slope is determined according to relevant construction regulations.
After the foundation pit is opened, the foundation pit side slope needs to be reinforced through soil nails made of reinforcing steel bars, a soil nail anti-pulling experiment is carried out before reinforcement, and the soil nail anti-pulling experiment can effectively ensure that a good reinforcement effect can be achieved after the soil nail wall is constructed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the soil nail of testing soil nail resistance to plucking ability among the prior art and be non-standard spare for the test result is inaccurate, and soil nail inserts foundation ditch wall degree of depth uncontrollable, and the shortcoming of tensiometer is harmd easily to the insertion-in-process, and the resistance to plucking experimental frock for foundation ditch soil nail that proposes.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a resistance to plucking experimental frock for foundation ditch soil nail, including the mount pad, the welding of mount pad bottom has the bottom plate, the welding of bottom plate bottom has the staple, and the inboard welding in mount pad top has the stand pipe, the stand pipe inside callipers is equipped with the depression bar, the welding of depression bar bottom has the clamp plate, the welding of clamp plate bottom has the test nail, and the welding of mount pad top has the support frame, the card of support frame top is equipped with the pull rod, the pull rod bottom is fixed with the tensiometer, and pull rod surface cover is equipped with the spring, the tensiometer measurement end has cup jointed the connecting rod, and the welding of pull rod top has the hand (hold).
Preferably, the spring is positioned inside the top of the support frame, and the bottom end of the spring is in contact with the top of the tension meter.
Preferably, the top end of the guide tube penetrates through and extends to the outer side of the top of the mounting seat.
Preferably, the bottom end of the connecting rod penetrates through and extends to the inner side of the top of the mounting seat, and the bottom of the connecting rod is welded and fixed with the upper surface of the pressing plate.
Preferably, the top of the pressure rod is welded with a hammering plate.
The utility model has the advantages that:
the device can insert the soil nail that the test was used more conveniently in the foundation ditch that needs the test, and the male degree of depth is unified, has effectively guaranteed the accuracy of test, and when extracting soil nail, the spring can effectively reduce the striking of tensiometer, reduces its risk of damaging.
Drawings
Fig. 1 is a schematic structural view of an anti-pulling test tool for foundation pit soil nails provided by the utility model;
fig. 2 is the utility model provides a overlook the structural schematic diagram of an anti-pulling test frock for foundation ditch soil nail.
In the figure: 1. a mounting base; 2. a base plate; 3. fixing nails; 4. a guide tube; 5. a pressure lever; 6. pressing a plate; 7. testing the nail; 8. a support frame; 9. a pull rod; 10. a tension meter; 11. a spring; 12. a connecting rod; 13. a handle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, an anti-pulling test tool for foundation pit soil nails comprises an installation base 1, a bottom plate 2 is welded at the bottom of the installation base 1, fixing nails 3 are welded at the bottom of the bottom plate 2, a guide pipe 4 is welded at the inner side of the top of the installation base 1, a pressure rod 5 is clamped in the guide pipe 4, a pressure plate 6 is welded at the bottom of the pressure rod 5, a test nail 7 is welded at the bottom of the pressure plate 6, a support frame 8 is welded at the top of the installation base 1, a pull rod 9 is clamped at the top of the support frame 8, a tension meter 10 is fixed at the bottom of the pull rod 9, a spring 11 is sleeved on the surface of the pull rod 9, a connecting rod 12 is sleeved at the metering end of the tension meter 10, and a handle 13 is welded at the top end of the pull rod 9.
In this embodiment, insert the staple 3 in the foundation ditch that needs the test, because the bigger and surperficial toper pad of having seted up of 3 diameters of staple, can effectively avoid equipment and foundation ditch in the test process to drop, the hammering board at 5 tops of hammering depression bar afterwards, the stand pipe 4 plays the guide effect to depression bar 5, makes test nail 7 insert perpendicularly in the foundation ditch, until 6 bottoms of clamp plate and foundation ditch surface contact for test nail 7 male degree of depth is fixed.
Furthermore, the user can step on the bottom plate 2 during testing, when preventing to pull handle 13 outward, extract the foundation ditch with whole equipment, hold handle 13 and outwards stimulate afterwards, the drawing that produces will show on tensiometer 10, when the pulling force reaches a definite value, connecting rod 12 can pull out clamp plate 6, make test nail 7 break away from the foundation ditch, the maximum power that extracts test nail 7 and produces will show on the display of tensiometer 10, because extract test nail 7 can make the foundation ditch lose pressure and frictional force to test nail 7 in the twinkling of an eye, therefore under the pulling force effect of pulling handle 13, the top of tensiometer 10 can strike the inside of top of support frame 8, consequently on pull rod 9 surface, be located and overlap a spring 11 and protect tensiometer 10 between the inside of support frame 8 top, prevent it from hitting badly.
The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
