Description
Изобретение относитс к строительству и может быть использовано, в частности при возведении фундаментов.The invention relates to the construction and can be used, in particular, in the construction of foundations.
Цель изобретени - ускорение процесса испытани .The purpose of the invention is to accelerate the testing process.
На фиг. 1 схематически изображена сва в процессе испытани ; на фиг.2 - график зависимости смещение - усилие, получаемый в результате испытани .FIG. 1 shows schematically the pile during the test; Fig. 2 is a plot of displacement versus force obtained as a result of the test.
Способ статического испытани сваи включает приложение возрастающего по величине и противоположно направленного осевого усили 1 одновременно к изолированным друг от друга стволу 2 и п те 3 и одновременное измерение перемещений ствола 2 и п ты 3 сваи, которые провод т до срыва ствола 2.The method of static testing of a pile includes the application of increasing in magnitude and oppositely directed axial force 1 simultaneously to barrel 2 and pin 3 insulated from each other and simultaneous measurement of the movements of barrel 2 and pin 3 of piles, which are carried out until the shaft 2 is broken.
Способ реализуют следующим образом.The method is implemented as follows.
К изолированным друг от друга стволу 2 и п те 3 посредством силового элемента, например домкрата, одновременно прикладывают равные по величине и противоположно направленные усили 1. По мере возрастани нагрузки измер ют перемещени п ты 3 и ствола 2 сваи и стро т зависимость 4 смещение - усилие дл ствола 2 и зависимость 5 смещение - усилие дл п ты 3 сваи.Equal and oppositely directed forces 1 are simultaneously applied to a barrel 2 and pt 3 insulated from each other by means of a power element. For example, displacement of pt 3 and trunk 2 piles are measured as the load increases and the dependence 4 is plotted. force for stem 2 and dependence 5 displacement - force for five piles of pile 3.
При достижении усили срыва ствола сваи- зависимость 4 параллельна оси смещений- испытание заканчивают.When the breaking force of the barrel is reached, the pile 4 is parallel to the displacement axis - the test is completed.
Зависимость 5 смещение - усилие дл п ты 3 сваи при значени х усилий, превышающих усилие срыва ствола 2, экстраполируют в виде пр мой с тем же углом наклона, что и зависимость смещение - усилие дл п ты 3 при усили х, близких к срыву ствола 2. Зависимость смещение - усилие дл сваи в целом наход т сложением зависимостей 4 и 5.Dependence 5 displacement - force for a fifth of 3 piles at values of force exceeding breakdown force of trunk 2, is extrapolated in the form of a straight line with the same angle of inclination as the dependence displacement - force for fifth of 3 at forces close to breakdown of the trunk 2. Dependence displacement - the force for the pile as a whole is found by adding dependencies 4 and 5.
