Laboratory of Success

Palmyra Mibonia, deputy head of the construction laboratory of the branch "Cosmodrome" Vostochny "Dalspetsstroy

Laboratory of Success

The cosmodrome is an area of ​​increased danger and responsibility. There are high pressure gases, fire and explosive substances, noises, and vibrations. All these features are taken into account both at the design stage and during construction. As a rule, advanced, most durable and resistant materials to aggressive environments are chosen for such objects.

To control the quality of materials and technological processes, a construction laboratory was created in 2012 on the basis of the Vostochny Cosmodrome branch of Dalspetsstroy. A well-coordinated team of professionals works here.

Palmira Mibonia, deputy head of the construction laboratory of the Vostochny Cosmodrome branch of Dalspetsstroy, was one of the first to come to the Vostochny construction site. 

Palmira Mibonia: “When I first arrived at the cosmodrome, there was only a foundation pit at the place where we see the launch facility today. On a special vehicle, we went down to the very bottom. Evaluated the stability, the coefficient of soil compaction at each horizon. Before pouring the foundation of the launch structure, the soil was checked by the cutting ring method and the stamp method. The job is not easy. There is dust and dirt all around, and we, dressed as astronauts before launch, check every inch of the earth. The big laboratory, which we see now, did not exist yet, there was only one trailer. "

Today all conditions have been created in the laboratory in order to carry out non-destructive and destructive testing. The laboratory carries out incoming control of inert materials, operational, shock-pulse, ultrasonic and destructive control. Experts possess basic diagnostic techniques, and can, if necessary, determine by eye the quality of the material and its technical characteristics are not worse than the device. The archive, which has been conducted since the beginning of construction, contains conclusions confirming the increased safety margin of all materials.

Palmyra Mibonia improved in her difficult profession at federal facilities: the Bureyskaya hydroelectric power station, bridges and roads of the Far East. But, according to her, none of these projects can compare with the Eastern one. 

“It is interesting to work here, since the volume of construction at the Vostochny cosmodrome is colossal. We check the composition of concrete and inert materials: soil, sand, crushed stone, as well as cement consumption and margin of safety. For the first time, such types of tests as checking of cellular blocks were carried out. This type of diagnostics is necessary before installing the facade system. " 

Without a special conclusion confirming the frost resistance, water resistance and strength of materials, the new stage of construction does not begin. Control of concrete mixes is carried out on applications on the first day of pouring, after a month and upon delivery of the object. 

“Up to 5 thousand applications for destructive and non-destructive testing are received annually. In just one month, 1400 concrete samples are tested for strength. "

The dynamics of work at the facilities was reflected in the work of the laboratory. The most difficult period was when concrete was poured around the clock at one of the most critical areas - the starting structure. Several operations were carried out simultaneously. At night, laboratory staff monitored the quality of pouring - the intensity of concrete delivery, laying with a vibratory roller, and in the morning they checked the samples for moisture, inertness, mobility and density.


“Another no less interesting example is the technical complex. In the assembly and testing building of the spacecraft, we checked only two floors for four days. An ultrasonic device was used to assess the thickness of the paint layer on each metal structure. The work was carried out on a special aerial platform that lifted us to the required height. " 

Often, one product is tested in different ways and with the participation of specialists from several laboratories. Thus, four methods were used to test the tightness of 400 cubic meter water storage tanks. The vertical seam was checked by X-ray gammagraphy, the cut-in hatch - by ultrasonic and capillary control, the bottom - by vacuum. Welded seams at the base of the highest structures of the cosmodrome - lightning rods have also passed the quality control of the UPP laboratory No. 723 of Dalspetsstroy.

According to Palmyra Mibonia, the entire laboratory is now awaiting a joyful event - the first launch: “From the very beginning, we saw how dynamically the construction proceeded. You leave the shift for two weeks, and when you return, you no longer recognize the objects - such dramatic changes have taken place. "
