Abstract
The utility model discloses a direct-reading type pile foundation displacement detection device. The direct-reading type pile foundation displacement detection device comprises a pile body which is divided into an upper pile main body and a lower pile main body, and further comprises a load detection device located in the lower pile main body and a displacement sensor arranged in the pile body. The displacement sensor is connected with the load detection device, an output wire of the displacement sensor is connected with a load tester located on the ground surface, and the load tester is connected with a loading system through a control wire. The direct-reading type pile foundation displacement detection device can test the actual displacement of a foundation file, and the measurement error is greatly reduced.
Description
Technical field
The utility model relates to the detection system of testing foundation pile carrying displacement in a kind of building foundation pile driving construction of using in architectural engineering construction technique field, specifically, relates 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, 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, 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 in this scheme, static load detects the value-added tax function step by step that analyzer 7 can only controlled loading system, 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.
