CEMENTITIOUS FOUNDATION CAP WITH POST-TENSIONED HELICAL ANCHORS

A post-tensioned concrete cap foundation has helical anchors with pipes having several helical discs welded around the pipe perimeter to spin drill deep into subsurface soils or other soft materials with holes in the pipe for high pressure-grouting in place. The helical anchor pipes are coupled to a...

description A post-tensioned concrete cap foundation has helical anchors with pipes having several helical discs welded around the pipe perimeter to spin drill deep into subsurface soils or other soft materials with holes in the pipe for high pressure-grouting in place. The helical anchor pipes are coupled to a tensioning element for pulling and post-tensioning the helical anchor. The helical anchors are tension anchors which can be converted to compression anchors. The helical anchors in tension serve to pull the foundation cap down to compress the underlying soil while the compression anchors limit the maximum settlement of the concrete foundation cap. The foundation also includes perimeter-forming and interior corrugated metal pipes with upper and lower sleeved horizontally extending radial bolts that are secured to the pipes and post-tensioned to provide lateral foundation compression. Un bouchon de fondation en béton post-contraint comprend des ancrages hélicoïdes avec des tuyaux ayant plusieurs disques hélicoïdes soudés autour de la circonférence des tuyaux pour forer en profondeur de sols en subsurface ou dans dautres matériaux mous, des trous étant dans les tuyaux pour le coulis de ciment à haute pression en place. Les tuyaux dancrage hélicoïdes sont raccordés à un élément de contrainte pour tirer et post-contraindre lancrage hélicoïde. Les ancrages hélicoïdes sont des ancrages de contrainte qui peuvent être convertis en ancrages de compression. Les ancrages hélicoïdes contraints servent à tirer le bouchon de fondation vers le bas pour comprimer le sol sous-jacent alors que les ancrages de compression limitent le tassement maximum du bouchon de fondation en béton. La fondation comprend également des tuyaux de métal ondulés de formation du périmètre et dintérieur ayant des boulons radiaux manchonnés horizontaux supérieurs et inférieurs qui sont fixés aux tuyaux et post-contraints pour fournir une compression de fondation latérale.
