Abstract
The present invention relates to a kind of anti-horizontal shear force hydraulic detection device of foundation pile, belong to the anti-horizontal shear force hydraulic detection device of foundation pile measuring foundation pile bearing capacity in building foundation pile driving construction. It includes 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 steel reinforcement cage are welding as one, and lower shoe and hypomere steel reinforcement 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 present invention can not only detect foundation pile resistance to compression, anti-pulling capacity, and the shear rod adopted, can strengthen pile detection complete after shear strength at load box lower shoe place, make pile foundation anti-horizontal shear strength after having detected not only will not reduce, can strengthen on the contrary.
Description
Technical field
The present invention relates to a kind of anti-horizontal shear force hydraulic detection device of foundation pile, belong to the anti-horizontal shear force hydraulic detection device of foundation pile measuring foundation pile bearing capacity in building foundation pile driving construction.
Background technology
The load box of the pile bearing capacity detection now used, it is mounted at the bottom of foundation pile stake or the stage casing of stake, by upper plate, pressure unit, lower shoe, displacement bar, displacement pillars etc. form, 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 disconnects at load box lower shoe place with hypomere stake, hydraulic oil between plunger and the cylinder body of complete depended on pressure unit plays support and is connected, support interconnection function can be played when pressure unit loads, when pressure unit unloads, hydraulic oil does not have pressurized cannot play interconnection function, oil cylinder annular cross-sectional area can only be leaned on to bear horizontal shear force, anti-horizontal shear force is poor. the pile foundations such as the heavy construction bigger for span and bridge leave potential safety hazard.
Summary of the invention
In order to overcome drawbacks described above, it is an object of the invention to provide a kind of anti-horizontal shear force hydraulic detection device of foundation pile, can detection of pier foundation resistance to plucking, Compressive Bearing Capacity, can increase again pile detection complete after at the anti-horizontal shear force hydraulic detection device of foundation pile of the anti-horizontal shear strength at load box lower shoe place, make pile foundation anti-horizontal shear strength after having detected not only will not reduce, can strengthen on the contrary.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of anti-horizontal shear force hydraulic detection device of foundation pile, it includes 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 steel reinforcement cage are welding as one, and lower shoe and hypomere steel reinforcement 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.
Pressure unit is outside installs the shear rod identical with steel reinforcement cage main muscle quantity.
The upper end of shear rod and the lower surface of upper plate are welded as a whole, the lower end traverse lower shoe of shear rod.
The lower end of shear rod adopts double nut also tight through lower shoe and leaves 100mm surplus.
At the outside protective cover of installing of nut, protective cover adopts full weld to be connected with lower shoe place.
Displacement pillar it is cased with outside displacement bar.
Can effectively be connected with the hypomere stake of foundation pile, after having detected, foundation pile gap be mended slurry, make upper and lower section of stake be 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 adopted, can strengthen pile detection complete after shear strength at load box lower shoe place, make pile foundation anti-horizontal shear strength after having detected not only will not reduce, can strengthen on the contrary.
Accompanying drawing explanation
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:
A kind of anti-horizontal shear force hydraulic detection device of foundation pile, it includes 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 and foundation pile epimere steel reinforcement cage are welding as one, and lower shoe 4 and hypomere steel reinforcement cage are welding as one, 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.
Pressure unit 3 is outside installs the shear rod 5 identical with steel reinforcement cage main muscle quantity.
The lower surface of the upper end of shear rod 5 and upper plate 2 is welded as a whole, the lower end traverse lower shoe 4 of shear rod 5.
The lower end of shear rod 5 adopts double nut and tight and leave 100mm surplus through lower shoe 4. Using the stroke as pressure unit.
At the outside protective cover 7 of installing of nut 6, protective cover 7 adopts full weld to be connected with lower shoe 4 place.
Displacement pillar it is cased with outside displacement bar 8.
After displacement bar is used for measuring foundation pile bearing load, whether qualified the upper plate of the anti-horizontal shear force hydraulic detection device of foundation pile and the displacement of lower shoe, 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 foundation pile anti-horizontal shear force at load box lower shoe place, make the foundation pile anti-horizontal shear force after having detected not only will not reduce, can increase on the contrary.
