For this purpose to the leg (item 6) is fastened the clock-like travel indicator ICh – 50 (item 5). The test-point of the travel indicator is taking stand on the floor model. Travel indicator ICh – 50 was produced at Kirovsk toolmaker (Russia) and has grating period of 0,01 mm and measurement range of 0-50 mm. The facility built allows to employ the end of the floor model with the power which directed both vertically upwards and vertically downwards (at the pic. 2P.3.11 is shown the configuration when there is a bend upwards). For the testing with a bend downwards the balk (item 3) is fixed to the ice with the help of ice-axes and adjustable jack and dynamometer is fixed to the free end of the floor model over the balk.


(1 – dynamometer, 2 - hydraulic jack, 3 – metal balk, 4 – loading plate, 5 – travel indicator, 6 – travel indicator`s leg.


Picture 2P.3.11 Facility for testing the floor models of ice during a bend.)


The built shown at the picture 2P.3.11 allows to do the testing of the ice which has the width no more than 1 m. When the ice has a bigger width the large scale hardness during a bend can be measure with the help of empiric formula connecting large scale hardness with middle integral hardness during the bend of the disks (Krupina, Kubyshkin).


 


Where   is a calculation limit of the ice hardness during the bend of the floor models sawed up at the ice thickness, MPa.


 is a middle integral ice hardness during the disk`s bend according to the methodology described in the item 2.3.6.


SIGHTINGS AT THE ICE DRIFT


Sightings at the ice drift are produced with the method of standing the drifting buoys which are kitted out with the system of geopositioning (GPS) and the systems of communication with the help of satellite channel ARGOS (radio lighthouse “Pulsar” produced by closed joint-stock company “ES-PAS”, Russia) which allows to receive the data about long-period drift of the objects` sighting which have additional thermistor chains they let to characterize temperature profile at 10 horizons. The information about the quantity of the buoys, positions of the places of standing, periods of information passing are presented in the table 6.8.1 of the volume 3 of Technical account. Technical characteristics of the buoys are presented at the tables 2П.4.1. and 2П.4.2. Measurement levels of temperature are counted from the middle of the buoys` framework. For the mounting of buoys people choose the places with flat shore ice circled with little toroses.

Traveling locus of the buoys of both types is divided by the results of dimensions of the GPS receiving sets positions or with the help of the system “ARGOS”.


The periodicity of the information delivery with the help of buoys is one hour. The results of the announcements are transmitted to the website FFF.


Data readout in the format MS Excel is producing in XXX 2 times a week.


Before the positioning on ice bodies you should include buoys in test run mode at the period no shorter than twelve hours. After the confirmation from XXX about their operation the devices should be thought as valid for standing on ice float.


Buoys stop working when the ice on which they were established is destroyed.


2.5 UNDERWATER TECHNICAL VIDEOSHOOTING


Underwater technical videoshooting was created for visualization of the underwater surface of ice channel. The shooting was done on the 12-th, 21-st of April and the 13-th of May 2013 with the usage of remotely operated underwater device «VideoRay Pro III» complete with colour videocam, two lights, two horizontal props and a vertical one. Technical characteristics of the device are presented in the table 2П.5.1. Total amount of videomaterial is 3 hours.

Picture 2П.5.1. Underwater technical videoshooting was done at the same piece of land as all the sighting over its evolution. Myna for the descending of remotely operated underwater device was prepared in the channel centre, for the underwater orientation at one side from the myna at 1 metre from it and under the ice was descended a pennant with the cloth downwards. Remotely operated underwater device operated from the tent standing near the channel edge and was shooting the underwater ice surface with the record on DVD-recorder (picture 2П.5.1).
