Abstract
A direct-reading pile foundation displacement detection device comprises a pile body, a load detection device and a displacement sensor, wherein the pile body includes an upper pile body and a lower pile body, the load detection device is positioned inside the lower pile body, and the displacement sensor is arranged inside the pile body. The displacement sensor is connected with the load detection device, an output lead of the displacement sensor is connected with a load tester positioned on the ground, and the load tester is connected with a loading system through a control lead. The direct-reading pile foundation displacement detection device can test real displacement of foundation piles, and measuring errors are greatly reduced.
Description
Technical field
The present invention relates to the detection system of test foundation pile carrying displacement in a kind of building foundation pile driving construction of using in the architectural engineering construction technique field, 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, on 14, weld, the bottom offset bar, in figure, 1 is the top offset bar, 2 is the 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, 5 base is fixed on datum line beam 3, on, bottom offset sensor 4, 5 contact and upper, bottom offset bar 1, 2 upper surface connects, the output line of two displacement transducers is connected with M signal conversion equipment 6, and then be connected on static load detection analyzer 7, static load detects analyzer 7 and loads step by step through control year case 8 controlled loading systems 19.But static load detects the value-added tax function step by step that analyzer 7 can only the controlled loading system in this scheme, can not realize offloading functions step by step; And upper and lower displacement bar 1,2 is longer, because deadweight easily produces 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 that greatly affects foundation pile carrying displacement even can not be measured displacement.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, adapt to the reality needs, a kind of direct-reading pile foundation displacement checkout gear is provided.
In order to realize purpose 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 that is positioned at lower pile body inside, also comprise the displacement transducer that is arranged at pile body inside, described displacement transducer is connected with Weight detector, and the output lead of described displacement transducer is connected with the load test instrument that is positioned at earth's surface, and described load test instrument is connected with loading system through pilot.
Described displacement transducer 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 directly with the upper and lower base plate of Weight detector, is connected, and can test the real displacement of foundation pile, and measure error reduces greatly;
2. do not need displacement bar and displacement sheath are installed, easy for installation, cost is low;
3. the small volume of displacement transducer, be directly installed on the upper and lower base plate of Weight detector, between detecting, is not easy to damage;
4. the output line of displacement transducer directly is connected on the load test instrument, and the data that record are more accurate;
But 5. both Artificial Control of load test instrument, the directly loading step by step of controlled loading system, unloading, ftercompction process again, realize full-automatic, unattended function.
The accompanying drawing explanation
Fig. 1 is the structural representation of prior art pile foundation bearing capacity displacement detector;

Described displacement transducer comprises top offset sensor 16 and bottom offset sensor 17, and described top offset sensor 16 is connected with the upper plate 13 of described Weight detector 12, and described bottom offset sensor 17 is connected with the lower shoe 14 of Weight detector 12.
Displacement transducer is arranged at pile body inside and directly with the upper and lower base plate of Weight detector, is connected, and can test the real displacement of foundation pile, and measure error reduces greatly;
With the displacement bar structure of prior art, compare, do not need to install displacement bar and displacement sheath, easy for installation, cost is low;
The small volume of displacement transducer, be directly installed on the upper and lower base plate of Weight detector, between detecting, is not easy to damage;
The output line of displacement transducer directly is connected on load test instrument 18, and the data that record are more accurate;
But the load test instrument is Artificial Control both, the directly loading step by step of controlled loading system, unloading, ftercompction process again, realize full-automatic, unattended function.
What embodiments of the invention were announced is preferred embodiment, but is not limited to this, 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 variation; but only otherwise break away from spirit of the present invention, all in protection scope of the present invention.
