Description
Vynález rieši zariadenie na skúšanie osové zatažených na mieste zhotovených pilot. Zariadenie umožňuje zaobísť sa bez zaťažovacieho mosta s protizáťažou alebo bez zaťažovacieho mosta kotveného.The present invention provides an apparatus for testing axial retracted on-site piles. The device allows to operate without a load bridge with or without an anchored load bridge.
Vynález sa týká odboru stavebníctva — zakladanie stavieb. Podstata vynálezu spočívá v tom, že sa zdvihákom umiestneným nad terénom zatláča pomocou posuvné uloženej rozpery oddělená pata piloty smerom dole. Súčasne sa pomocou ťahadiel vyťahuje oddělený driek piloty smerom hoře. Plášťové trenie a tiaž drieku piloty sa využívá ako reakcia pri zatláčaní paty piloty a naopak, odpor zeminy pod pátou piloty sa využívá ako reakcia pri vytahovaní drieku piloty.The invention relates to the field of construction - building foundation. The essence of the invention is that a separate pile heel is pushed downwards by means of a slidable spacers located above the terrain. At the same time, a separate pile shaft is pulled upward by the pullers. Sheath friction and pile shaft weight is used as a response to pile heeling and vice versa, soil resistance under the fifth pile is used as a response to pile stem removal.
Zariadenie podía vynálezu je vyobrazené na jednom výkrese o dvoch obrázkoch. 2The device according to the invention is shown in one drawing of two figures. 2

Vynález rieši zariadenie na skúšanie na mieste zhotovených pilot.The invention addresses a pilot site test apparatus.
Doteraz známe zariadenia si vyžadujú vybudovanie kotveného zaťažovacieho mosta, zaťažovacieho mosta s protizáťažou alebo inej nadzemnej konštrukcie pre zachytenie reakcie skúšobného zaťaženia, čo si vyžaduje zvýšenie nákladov, zvyšuje prácnosť a časovú náročnost’.Up to now known devices require the construction of an anchored load bridge, a load bridge with a counterweight or other overhead structure to accommodate the test load response, which requires increased costs, increases labor and time consuming.
Jedno z doteraz známých zariadení na skúšanie pilot sice umožňuje skúšať piloty bez zaťažovacieho mosta, ale osadenié tohto zariadenia na patu piloty je však v niektorých případech náročné. Náročné je tiež získanie skúšobného zariadenia na opátovné použitie, pretože je potřebné driek skúšobnej piloty odkopať a vytiahnuť na povrch terénu.While one of the pile testing devices known to date allows pilots to be tested without a load bridge, however, the installation of this device on the pile base is difficult in some cases. It is also challenging to obtain a test device for reuse, since it is necessary to kick the test pillar and pull it to the surface of the terrain.
Nedostatky vyššie uvedených zariadení na skúšanie na mieste zhotovených pilot odstraňuje zariadenie podlá vynálezu, ktorého podstata spočívá v tom, že zdvihák je umiestnený nad terénom na rozpere posuvné uloženej vo výpažnici osadenej v ťažisku prierezu drieku piloty. Rozpera je uložená na pate piloty, oddelenej deliacou doskou od drieku piloty. Na zdviháku je uložená oporná doska spojená ťahadlami s vystuženým driekom piloty. I Zariadenie na skúšanie na mieste zhotovených pilot podlá vynálezu má výhody v tom, že sa zdvihák osadzuje nad povrchoví terénu, takže je počas skúšania piloty volné přístupný. Zdvihák sa dá počas skúšania piloty kontrolovat’ a upravovať. Po ukončení skúšky sa móže zariadenie jednoducho demontovat’ a znovu použiť. Příklad vyhotovenia skúšobného zariadenia pódia vynálezu je na výkrese. Na obr.' 1 je schematicky vyznačený zvislý rez pilótou a skúšobným zariadením, na obr. 2 je vyznačený priečny rez pilótou a skúšobným zariadením v rovině I-I.The drawbacks of the above-mentioned on-site test apparatuses are eliminated by the device according to the invention, the principle of which is that the jack is located above the terrain on a spreader disposed in the wall of the pile shaft. The spacer is mounted on the pile of the pile, separated by a split plate from the pile shaft. A support plate is mounted on the jack, coupled with the pull rods with a reinforced pile shaft. The pilot site testing apparatus of the present invention has the advantage that the jack is mounted above the surface of the ground so that it is freely accessible during pilot testing. The jack can be checked and adjusted during pilot testing. After the test, the device can be easily removed and reused. An example of an embodiment of the test apparatus according to the invention is in the drawing. FIG. 1 is a schematic vertical section through a pile and a test device; FIG. 2 shows a cross-section through a pile and a test device in the I-I plane.
Skúšobné zariadenie podía vynálezu pozostáva z rozpery 4 posuvné uloženej vo výpažnici 5 v střede vystuženého drieku piloty 8 a troch ťahadiel 6 vo výpažniciach 7, spojených s opomou doskou 2. So zariadením podía vynálezu sa pracuje tak, že zdvihákom 1 sa zatláča pomocou rozpery 4 pátá piloty 3 v smere osi piloty zvisle alebo šikmo dole, pričom sa súčasne driek piloty 8 oddělený deliacou doskou 9 od- paty piloty prostredníctvom ťahadiel 6 vytahuje smerom hoře. V uvedenom příklade je použitý jeflen zdvihák 1 a tri ťahadlá 6. V závislosti na priemere paty piloty 3, drieku piloty 8, tvaru prierezu piloty, priemere zdviháka 1 a velkosti skúšobného zaťaženia možno použiť iný počet zdvihákov 1 a ťahadiel 6. Pri vyšších požiadavkách na přesnost’ stanovenia skúšobného zaťaženia sa móže každý zdvihák 1 opatřit’ běžným dynamometrom.The test device according to the invention consists of a spacer 4 slidably supported in the die 5 in the center of the pillar shaft 3 and three drawers 6 in the casings 7 connected to the support plate 2. The apparatus according to the invention is operated by pushing the jack 1 by means of a spacer 4 5. the pile 3 in the direction of the pile axis vertically or obliquely downwards, while the pile shaft 8 separated by the pile base plate 9 by the pullers 6 is pulled upwards. In this example, a jack 1 and three drawers 6 are used. Depending on the diameter of the pile heel 3, the pile shaft 8, the pile shape, the jack diameter 1 and the test load size, a different number of jacks 1 and 6 may be used. the accuracy of determining the test load may be provided with a conventional dynamometer by each jack 1.
