Abstract
The utility model discloses a detecting device for upright resistance of an anchorage body, which comprises a base plate, a hydraulic jack, a pressure sensor, a displacement sensor and a data processing center, wherein the hydraulic jack acts on the base plate which is fixed on the anchorage body; and the pressure sensor and the displacement sensor are respectively arranged on the hydraulic jack and are respectively connected with the data processing center. In the detecting device, the pressure sensor and the displacement sensor are used for acquiring data, the data processing center is used for synchronously recoding data, and therefore, the data acquisition is real-time, accurate and reliable.
Description
Technical field
The utility model relates to a kind of checkout gear of anchoring body, in particular a kind of withdrawal resistance of anchoring body checkout gear.
Background technology
Anchoring body (comprising anchor pole and anchor cable) has certain disguise after construction is finished, can not find out its work and stress intuitively, and uplift resistance is necessary it is detected evaluation as the important evaluation index of anchoring body construction quality quality.On-the-spot withdrawal resistance of anchoring body detects test (acceptance test) and detects the most direct effective method as uplift resistance, helps not only guaranteeing that construction quality is safe and reliable, can the construction safety and the punishment effect of whole slope project be made a determination.Simultaneously, the stability of estimating the prediction side slope and development trend etc. are all had extremely important meaning, the accuracy of its testing result directly has influence on the reliability to the safety evaluatio of slope project.
At present, there are problems in the existing conventional detecting instrument, as oil pressure reading instability, causes pressure control inaccuracy, and the displacement detecting conventional method is as measuring with slide measure, and precision is low, and displacement data can not in time not reflect etc.Most critical be that pressure, displacement control efficiency are low, usually cause data distortion and problem such as discontinuous, the pull-out test result reliability is low.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of withdrawal resistance of anchoring body checkout gear is provided, and has realized the detection that withdrawal resistance of anchoring body is detected by being used of hydraulic jack, pressure sensor and displacement transducer
Technical scheme: the utility model comprises backing plate, hydraulic jack, pressure sensor, displacement transducer and data processing centre; Wherein: hydraulic jack acts on the backing plate, and backing plate is fixed on the anchoring body, and pressure sensor and displacement transducer are arranged at respectively on the hydraulic jack, and pressure sensor links to each other with data processing centre respectively with displacement transducer.
Beneficial effect: the utility model has the following advantages compared to existing technology, the utility model pressure sensor and displacement transducer image data, and by data processing centre's synchronous recording data, data acquisition is in real time, accurately, reliably.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises backing plate 2, hydraulic jack 3, pressure sensor 4, displacement transducer 5 and data processing centre 6; Wherein: hydraulic jack 3 acts on the backing plate 2, backing plate 2 is fixed on the anchoring body 1, pressure sensor 4 and displacement transducer 5 are arranged at respectively on the hydraulic jack 3, pressure sensor 4 links to each other with data processing centre 6 respectively with displacement transducer 5, hydraulic jack 3 is the driving hierarchical loading of motor externally, anchoring body 1 is carried out drawing, pressure sensor 4 and displacement transducer 5 real time record pressure and displacement datas, and give data processing centre 6 with related data transmission, carry out analyzing and processing by data processing centre 6.
For accurately recording the elongation in anchoring body 1 stretching process, should guarantee the elongation end and test anchoring body 1 compatible deformation of displacement transducer 5 during installation.Because the variable elongation of anchoring piece is the inner core with hydraulic jack 3, urceolus is fixed, and the slip elongation end of displacement transducer 5 links to each other with the inner core of hydraulic jack 3, and the Slide Box of displacement transducer 5 is arranged at the urceolus of hydraulic jack 3.
