For loading test) and thermal analysis system (or heat anomaly method, hereinafter referred to as TIP method) detection device.These detection devices are each
There is its applicable elements.
Wherein, the principle of TIP method is the principle generated heat using concrete hydrating reaction at the beginning of pile concrete pours,
The temperature at pile body different depth is measured, temperature height is closed to the dosage of concrete and quality (whether there is defect) in related
Uniformly whether system analyze pile concrete along the relative different of pile body according to the absolute value of temperature and temperature and pour, and pile body is
No complete, steel reinforcement cage places whether eccentric, calculating steel reinforcement cage cement protective layer thickness etc..
There are two types of device form, the forms of (1) thermal probe and (2) pre-buried electric heating cable for existing TIP detection.
(1) probe of thermal probe method is moved up and down in built-in pipe, acquires a data by every a distance
Mode is acquired the temperature of each point in pipe.The advantages of the method, is: it is at low cost, after buying primary equipment, can Reusability,
But its disadvantage is also apparent from: because the heat of hydration only generates in 12-72h, and influence factor is more, (such as weather, temperature, week
Whether side soil layer has cement additive etc.), even if carrying out manual testing in the specific time, also it is not easily found optimal survey
Try time point, and high labor cost；In addition, the contactless infrared temperature probe of the probe of the method, indirectly testing and when stopping
Between it is shorter, measuring accuracy will receive influence.
(2) mode of electric heating cable guarantees that sensor is not damaged in early days, as long as the later period sets when pre-buried electric heating cable
Acquisition time interval, sensor will periodically be read, as long as engineer finally transfers data in host, analysis of going back is
It can.The advantages of this mode is: high degree of automation, collected data volume is big, facilitates analysis, but its electric heating cable can only be in morning
Phase is pre-buried, and pre-buried after-pouring concrete can not just take out recycling, so the cost of consumable material is very high.

Send temperature data to the integrity tester.
Further:
Test tube wall axially spaced-apart setting described in the thermally conductive windowsill, and the thermally conductive window is equipped with thermally conductive sheet.
The testing tube is the non-conductor pipe of heat.
The sensor module includes scalable inductive head, can be close to the thermally conductive window.
The counter that the sensor module further includes connecting rod, is arranged in connecting rod, the scalable inductive head pass through
The counter is vertically connected at the one or both ends of the connecting rod.The connecting rod built-in power line and data line, make institute
State counter sent to by the order information of place connecting rod and by the temperature data of the scalable inductive head detection it is described
Integrity tester.
The scalable inductive head includes the spring of the inner conductors of inductive head and its connection.
The connecting rod is elastic rod.
Several described connecting rods are axially connected with each other by quick coupling along the testing tube.
Utility model has the advantages that the utility model keeps detecting devices recyclable, it is at low cost, and can carry out in time
Multiple real-time testing.
More specifically, the scalable inductive head of setting can be close to thermally conductive window, and because of the non-conductor material of heat
The isolation of testing tube, consecutive points heat transfer is bad, can more accurately measure the hydration heat of concrete of this part, realizes repeatedly real-time
High precision measurement.The counter of setting can be used for judging the place sequence of sensor module, to detect at pile body different depth
Temperature.
