Description
Technical field
The utility model belongs to building field, relates to the improvement of foundation pile shape and structure in the building field, is a kind of grouting behind shaft or drift lining concrete hollow fillet triangular pile specifically.
Background technology
The building materials of foundation pile engineering are more on market, if any pile tube, all kinds of square pile, castinplace pile, drilled pile etc.These pilings mainly are divided into non-prestressed member and prestressed member two large classes.The prestressed member piling comprises pile tube, centrifugal prestress square pile etc.Their shortcoming is, often fragility is larger, and is shorter from the cracking to the time to rupture, and pile body ductility is relatively poor, causes the moment building collapsing when earthquake occurs, and makes that personnel do not have the sufficient time escape in the building.
Existing concrete prefabricated units cross section is various, and many on the market is square and circular cross-section, and when conduct carrying effect member, its maximum purpose is to improve the pile body bearing capacity that unit materials can provide, thereby economical with materials reduces cost.The very large characteristics of preformed pile are a side and soil interaction, utilize the frictional force between stake and the soil to improve pile body bearing capacity.
Circular cross-section relatively and section ratio surface area less, therefore pile tube does not take advantage aspect the stake side-friction force improving; Square pile and soil body frictional force are larger, and the bearing capacity ratio pile tube is good, but solid square pile is heavy, feed consumption is many; Hollow square pile combines the advantage of pile tube and square pile preferably, and outer cross section is square, and interior cross section is circular, can improve a side-friction force comparatively speaking, but its cross section concrete thickness differs, and the frictional force of unit volume material also is not fully exerted.
The existing concrete prefabricated units, after pile sinking was finished, pile body itself did not contact with the soil body very and fits, and often needed the supporting capacity of the stop time competence exertion stake grown itself, and stake with between be connected relatively poor.
The utility model content
For the problems referred to above, main purpose of the present utility model is to provide that loss in a kind of building is few, material-saving, from the grouting behind shaft or drift lining concrete hollow fillet triangular pile of heavy and light.
