Abstract
The utility model discloses a kind of screw pile, it is characterized in that screw pile inner hollow, pile wall thickness is 120mm ~ 150mm, and cross bath is offered at pile body top, and the stake top cross bath degree of depth is 100mm.The every 50cm of pile body arranges stiffening rib, and stiffening rib is ring-type, and stiffening rib evagination outermost edge is of a size of 100mm ~ 150mm from stake outward flange, stiffening rib height is 100mm ~ 150mm, evagination size and screw pile wall thickness match, and side direction appearance is circular arc, are convenient to a spiral injection; The stake end, arranges sword pin, and sword pin is turbination, and sword pin is solid.The utility model saves 25% ~ 35% than conventional piles material cost.
Description
Technical field
The utility model relates to a kind of screw pile, is applicable to civil engineering groundwork basic field.
Background technology
Stake is the effective means of soft ground treatment, and can be divided into preformed pile and non-preformed pile according to stake production method, traditional construction of prefabricated piles mode is generally static pressure and squeezes into or hammer driven.By comparing screw pile and straight stake, because screw pile is spiral injection, and straight stake is directly squeezed into, and the frictional force that obvious screw pile can provide is more much bigger than straight stake, thus the straight pile capacity of screw pile bearing capacity ratio wants large.Given this, being destroyed as long as screw pile is unlikely when constructing, if replace traditional driven pile to significantly improve pile capacity with screw pile, being obtained obvious economic benefit.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of screw pile with larger frictional resistance, solves the deficiencies in the prior art.
For this reason, the screw pile that the utility model provides, comprise by the prestressing force prefabricated pipe pile body adopting high-strength concrete to make, pile body rotates protruding stiffening rib with around pile body shape of threads, and the bottom of pile body is with sword pin.
The screw pile inner hollow that the utility model provides, pile wall thickness is 120mm ~ 150mm, and cross bath is offered at pile body top, and the stake top cross bath degree of depth is 100mm.It is to dock with the cross-shaped fixtures of screw pile machine that cross bath object is offered at pile body top, and the cross bath at the cross-shaped fixtures docking pile body top of screw pile machine during construction, then by screw pile spiral press-in soil layer.The every 50cm of pile body arranges stiffening rib, and stiffening rib is ring-type, and stiffening rib evagination outermost edge is of a size of 100mm ~ 150mm from stake outward flange, and stiffening rib height is 100mm ~ 150mm, and evagination size and screw pile wall thickness match.Side direction appearance is circular arc, is convenient to a spiral injection; The stake end, arranges sword pin, and sword pin is turbination, and sword pin is solid, and sword pin is configured with and is beneficial to cutting soil layer.
The screw pile that the utility model provides with stiffening rib can produce very large frictional resistance, therefore in same bearer power situation compared with bored pile, material cost can save 25% ~ 35%.
