Abstract
The utility model relates to a horizontal shearing strength hydraulic detection device for a foundation pile, and belongs to the horizontal shearing strength hydraulic detection device for the foundation pile, which tests the carrying capacity of the foundation pile in the construction of the building foundation pile. The horizontal shearing strength hydraulic detection device comprises a liquid inlet pipe, an upper bottom plate, a pressure unit, a lower bottom plate, a nut, and a displacement rod, wherein the displacement rod comprises an upper displacement rod and a lower displacement rod, the upper bottom plate and an upper reinforcement cage of the foundation pile are welded into a whole, the lower bottom plate and a lower reinforcement cage are welded into a whole, the upper displacement rod is welded on the upper bottom plate, the lower displacement rod is welded on the lower bottom plate, and the pressure unit is mounted between the upper bottom plate and the lower bottom plate. The horizontal shearing strength hydraulic detection device can detect the crush resistance and uplift bearing capacity of the foundation pile, and an adopted shearing rod reinforces the shearing strength of the foundation pile on the lower bottom plate of a loading box after the detection, so that the horizontal shearing strength of the foundation pile is not reduced, but reinforced after the detection.
Description
Technical field
The utility model relates to the anti-horizontal shear force hydraulic detection device of a kind of foundation pile, belongs to the anti-horizontal shear force hydraulic detection device of foundation pile of measuring foundation pile supporting capacity in building foundation pile driving construction.
Background technology
The pile bearing capacity now using detects the load box of use, at the bottom of it is mounted in foundation pile stake or the stage casing of stake, by upper plate, pressure unit, lower shoe, displacement bar, the compositions such as displacement pillar, when load box is loaded, the cylinder body of load box pressure unit drives epimere stake to move upward, plunger drives hypomere stake to move downward, after having detected, the epimere stake of foundation pile and hypomere stake disconnect at load box lower shoe place, hydraulic oil between plunger and the cylinder body of depended on pressure unit plays support and connection completely, in the time that loading, pressure unit can play support and connection effect, in the time that pressure unit unloads, hydraulic oil does not have pressurized cannot play connection function, can only lean on oil cylinder annular cross-sectional area to bear horizontal shear force, anti-horizontal shear force is poor.The pile foundation such as heavy construction and bridge larger for span left potential safety hazard.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model is to provide a kind of foundation pile anti-horizontal shear force hydraulic detection device, can detection of pier foundation resistance to plucking, Compressive Bearing Capacity, after increasing again foundation pile and having detected at the anti-horizontal shear force hydraulic detection device of foundation pile of the anti-horizontal shear strength at load box lower shoe place, pile foundation not only can not be reduced having detected rear anti-horizontal shear strength, can strengthen on the contrary.
To achieve these goals, the utility model adopts following technical scheme:
The anti-horizontal shear force hydraulic detection device of a kind of foundation pile, it comprises feed tube, upper plate, pressure unit, lower shoe, nut and displacement bar; Described displacement bar is divided into top offset bar and bottom offset bar;
Upper plate and foundation pile epimere reinforcing cage are welding as one, and lower shoe and hypomere reinforcing cage are welding as one, and top offset bar is welded on upper plate, and bottom offset bar is welded on lower shoe; Pressure unit is arranged between upper plate and lower shoe.
The outside installation of the pressure unit shear rod identical with the main muscle quantity of reinforcing cage.
The upper end of shear rod and the soffit of upper plate are welded as a whole, and the lower end of shear rod is through lower shoe.
The lower end of shear rod adopts double nut tight and leave 100mm surplus through lower shoe.
Protective cover is installed in outside at nut, and protective cover adopts full weld to be connected with lower shoe place.
There is displacement pillar at displacement bar overcoat.
Can effectively be connected with the hypomere stake of foundation pile, detected rear to foundation pile gap mend slurry, upper and lower section of stake is integrated.
The beneficial effects of the utility model are:
The utility model can not only detect foundation pile resistance to compression, anti-pulling capacity, and the shear rod adopting, after strengthening foundation pile and having detected, at the shear strength at load box lower shoe place, pile foundation not only can not be reduced having detected rear anti-horizontal shear strength, can strengthen on the contrary.
Brief description of the drawings
Fig. 1 is the utility model facade structures schematic diagram;
Fig. 2 is the utility model main perspective structural representation.
Detailed description of the invention
Be described in detail below in conjunction with 1,2 pairs of the utility model of accompanying drawing:
The anti-horizontal shear force hydraulic detection device of a kind of foundation pile, it comprises feed tube 1, upper plate 2, pressure unit 3, lower shoe 4, nut 6 and displacement bar 8; Described displacement bar 8 is divided into top offset bar and bottom offset bar;
Upper plate 2 is welding as one with foundation pile epimere reinforcing cage, and lower shoe 4 is welding as one with hypomere reinforcing cage, and top offset bar is welded on upper plate 2, and bottom offset bar is welded on lower shoe 4; Pressure unit 3 is arranged between upper plate 2 and lower shoe 4.
The outside installation of pressure unit 3 shear rod 5 identical with the main muscle quantity of reinforcing cage.
The soffit of the upper end of shear rod 5 and upper plate 2 is welded as a whole, and the lower end of shear rod 5 is through lower shoe 4.
The lower end of shear rod 5 adopts double nut tight and leave 100mm surplus through lower shoe 4.Using the stroke as pressure unit.
Protective cover 7 is installed in outside at nut 6, and protective cover 7 adopts full weld to be connected with lower shoe 4 places.
There is displacement pillar at displacement bar 8 overcoats.
Displacement bar is used for measuring after foundation pile bearing load, the upper plate of the anti-horizontal shear force hydraulic detection device of foundation pile and the displacement of lower shoe, and whether qualified the namely displacement of foundation pile, carry out judgement basis pile bearing capacity according to the displacement of foundation pile.
After shear rod has detected for foundation pile, increase the anti-horizontal shear force of foundation pile at load box lower shoe place, the anti-horizontal shear force of foundation pile after having detected not only can not be reduced, can increase on the contrary.
