Description
Technical field
The present invention relates in a kind of building foundation pile driving construction used in architectural engineering construction technique field the detection system of testing foundation pile carrying displacement, specifically, relate to a kind of direct-reading pile foundation displacement checkout gear.
Background technology
Pile bearing capacity displacement detector structure of the prior art as shown in Figure 1, the pile body 9 of foundation pile is divided into pile body 10 and lower pile body 11, the inside of lower pile body 11 is provided with Weight detector 12, upper at Weight detector 12, lower shoe 13, weld on 14, bottom offset bar, in figure, 1 is top offset bar, 2 is bottom offset bar, wherein, on, bottom offset bar 1, 2 outer cover are equipped with protecting pipe and straight-through earth's surface, and a datum line beam 3 is installed on earth's surface, on, bottom offset sensor 4, the base of 5 is fixed on datum line beam 3, on, bottom offset sensor 4, the contact of 5 and upper, bottom offset bar 1, the upper surface of 2 connects, the output line of two displacement transducers is connected with M signal conversion equipment 6, and then be connected on dead-load detection analyzer 7, dead-load detection analyzer 7 carries case 8 controlled loading system 19 multistage loadings through control.But dead-load detection analyzer 7 can only the multistage loadings function of controlled loading system in this scenario, can not realize offloading functions step by step; And upper and lower displacement bar 1,2 longer, easily produce owing to conducting oneself with dignity bending, affect displacement measurement precision and authenticity; And site environment is severe, in installation process and after installing, displacement bar easily hits curved, and the measuring accuracy greatly affecting foundation pile carrying displacement even can not measure displacement.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to reality need, a kind of direct-reading pile foundation displacement checkout gear is provided.
In order to realize object of the present invention, the technical solution used in the present invention is:
A kind of direct-reading pile foundation displacement checkout gear, comprise pile body, described pile body is divided into pile body and lower pile body, also comprise the Weight detector being positioned at lower pile body inside, also comprise the displacement transducer being arranged at pile body inside, institute's displacement sensors is connected with Weight detector, and the output lead of institute's displacement sensors is connected with the load test instrument being positioned at earth's surface, and described load test instrument is connected with loading system through pilot.
Institute's displacement sensors comprises top offset sensor and bottom offset sensor, and described top offset sensor is connected with the upper plate of described Weight detector, and described bottom offset sensor is connected with the lower shoe of Weight detector.
Beneficial effect of the present invention is:
1. displacement transducer is arranged at pile body inside and is directly connected with the upper and lower base plate of Weight detector, and can test the real displacement of foundation pile, measure error reduces greatly;
2. do not need to install displacement bar and displacement sheath, easy for installation, cost is low;
3. the small volume of displacement transducer, is directly installed on the upper and lower base plate of Weight detector, is not easy to damage between detection;
4. the output line of displacement transducer is directly connected on load test instrument, and the data recorded are more accurate;
5. load test instrument both can Artificial Control, again can the directly multistage loadings of controlled loading system, unloading, ftercompction process, realized full-automatic, unattended function.
Accompanying drawing explanation

Top offset sensor 16, for measuring the displacement of Weight detector 12 upper plate 13, namely goes up the displacement of pile body 10 after foundation pile bearing load; Bottom offset sensor 17 is for measuring the displacement of Weight detector 12 lower shoe 14, and under namely after foundation pile bearing load, whether qualified the displacement of pile body 11, carry out judgement basis pile capacity according to the displacement of foundation pile; Load test instrument 18 for controlled loading system 19 multistage loadings with unload step by step, ftercompction process, and the post processing of data, field print etc.
Displacement transducer is arranged at pile body inside and is directly connected with the upper and lower base plate of Weight detector, and can test the real displacement of foundation pile, measure error reduces greatly;
Compared with the displacement bar structure of prior art, do not need to install displacement bar and displacement sheath, easy for installation, cost is low;
The small volume of displacement transducer, is directly installed on the upper and lower base plate of Weight detector, is not easy to damage between detection;
The output line of displacement transducer is directly connected on load test instrument 18, and the data recorded are more accurate;
Load test instrument both can Artificial Control, again can the directly multistage loadings of controlled loading system, unloading, ftercompction process, realized full-automatic, unattended function.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto, those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present invention, and make different amplifications and change; but only otherwise depart from spirit of the present invention, all in protection scope of the present invention.
