Abstract

Przedmiotem zgłoszenia jest sposób formowania poszerzonej podstawy pala, gdzie w pierwszym etapie wykonuje się odpowiedni otwór w gruncie lub poniżej poziomu wody gruntowej wybraną dowolnie metodą korzystnie przez wwiercenie lub wwibrowanie rury obsadowej lub rury obsadowej z traconym butem, charakteryzujący się tym, że na dnie wykonanego otworu instaluje się środek strzałowy (2), w wyliczonej ilości, korzystnie od 1 kg do 2,5 kg, gdzie środkiem strzałowym (2) są górnicze materiały wybuchowe, korzystnie amonit, ergodyn lub trotyl, zaś środek strzałowy (2) jest połączony przewodem strzałowym (3) wyprowadzonym na zewnątrz otworu, a w kolejnym etapie podaje się do otworu beton konstrukcyjny w ilości obliczonej dla mocy ładunku i parametrów gruntu, tak aby wypełniał on nie mniej niż połowę otworu i dalej odpala się środek strzałowy (2), by w następnym etapie wypełnić do końca otwór betonem konstrukcyjnym.The subject of the application is a method of forming an extended pile base, where in the first stage an appropriate hole is made in the ground or below the groundwater level using any method, preferably by drilling or vibrating a casing pipe or casing pipe with a permanent shoe, characterized in that at the bottom of the hole a blasting agent (2) is installed in the calculated amount, preferably from 1 kg to 2.5 kg, where the blasting agent (2) is mining explosives, preferably ammonite, ergodium or TNT, and the blasting agent (2) is connected by a blasting duct (3) outside the hole, and in the next stage, structural concrete is fed into the hole in the amount calculated for the power of the load and soil parameters, so that it fills not less than half of the hole, and the blasting agent (2) is further ignited so that in the next stage fill the hole completely with structural concrete.
