Abstract
The invention relates to a foundation pile horizontal shear force resistant hydraulic detection device, which belongs to a foundation pile horizontal shear force resistant hydraulic detection device for measuring the bearing capacity of a foundation pile during building foundation pile construction. The foundation pile horizontal shear force resistant hydraulic detection device comprises a liquid inlet pipe, an upper base plate, a pressure unit, a lower base plate, a nut and a displacement rod, wherein the displacement rod is divided into an upper displacement rod and a lower displacement rod; the upper base plate and a steel reinforcement cage on the upper section of the foundation pile are welded into a whole; the lower base plate and a steel reinforcement cage on the lower section of the foundation pile are welded into a hole; the upper displacement rod is welded on the upper base plate; the lower displacement rod is welded on the lower base plate; and the pressure unit is arranged between the upper base plate and the lower base plate. The device can be used for detecting the press and uplift bearing capacity of the foundation pile; and a shearing rod is adopted, so that the shear strength of the foundation pile at the lower base plate of a load box after detection can be enhanced, and the shear strength of the foundation pile after detection cannot be reduced but enhanced.
Description
Technical field
The present invention relates to the anti-horizontal shear force hydraulic detection device of a kind of foundation pile, belong 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 object of the present invention is to provide the anti-horizontal shear force hydraulic detection device of a kind of foundation pile, 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 present invention 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 invention has the beneficial effects as follows:
The present invention can not only detect foundation pile resistance to compression, anti-pulling capacity, and the shear rod adopting, and 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 facade structures schematic diagram of the present invention;
Fig. 2 is main perspective structural representation of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing 1,2:
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;
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.
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.
