Description
Technical field
The invention belongs to building field, relate to the improvement of foundation pile shape and structure in the building field, is the stake of a kind of grouting behind shaft or drift lining concrete hollow fillet triangle specifically.
Background technology
The building materials of foundation pile engineering are more on market, if any pile tube, all kinds of side stake, castinplace pile, drilled pile etc.These pilings mainly are divided into non-prestressed member and prestressed member two big classes.The prestressed member piling comprises, pile tube, centrifugal prestress square pile etc.Their shortcoming is, often fragility is bigger, and is shorter from the time to rupture that ftractures, and pile body ductility is relatively poor, when earthquake takes place, causes the moment building collapsing, 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 as carrying effect member the time, its maximum purpose is to improve the pile body bearing capacity that unit materials can provide, thereby economical with materials reduces cost.The very big characteristics of preformed pile are a side and soil phase mutual effect, utilize the frictional force between stake and the soil to improve pile body bearing capacity.
Circular cross-section is relative and the section ratio surface area is less relatively, so do not take advantage at pile tube aspect the raising stake side-friction force; Side's stake is bigger with soil body frictional force, and the bearing capacity ratio pile tube is good, but solid side stake is heavy, feed consumption is many; Hollow square pile has combined the advantage of pile tube and side's stake preferably, and outer cross section is square, and interior cross section be a circle, 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 accomplished, pile body itself contact with the soil body and very fits, and often needed the supporting capacity of the stop time competence exertion stake of length itself, and with between be connected relatively poor.
Summary of the invention
To the problems referred to above, main purpose of the present invention 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 triangle stake of heavy and light.
The present invention solves above-mentioned technical problem through following technical proposals: the stake of a kind of grouting behind shaft or drift lining concrete hollow fillet triangle; Said grouting behind shaft or drift lining concrete hollow fillet triangle stake y direction is provided with the central through hole that runs through the stake of whole grouting behind shaft or drift lining concrete hollow fillet triangle; Interior all cross sections of said grouting behind shaft or drift lining concrete hollow fillet triangle stake are circular; The periphery cross section of said grouting behind shaft or drift lining concrete hollow fillet triangle stake is the fillet triangle; The stake of said grouting behind shaft or drift lining concrete hollow fillet triangle is identical in interior all cross section geometry of whole y direction, and the peripheral cross-section physical dimension is also identical, and said grouting behind shaft or drift lining concrete hollow fillet triangle pile length direction is extended with main muscle and the spiral stirrup around said main muscle; Said main muscle has three; Described three main muscle are positioned on three limits of fillet triangle hollow pile, and said main muscle is non-prestressed main muscle, are embedded with Grouting Pipe on three angles of fillet triangle hollow pile.
In a practical implementation example of the present invention, said main muscle is positioned on the mid point on three limits of triangle stake.
Positive progressive effect of the present invention is: grouting behind shaft or drift lining concrete hollow fillet triangle provided by the invention stake has the following advantages:
(1), grouting behind shaft or drift lining concrete pre-stress hollow fillet triangle provided by the invention stake, pre-buried Grouting Pipe in the pile body forming process behind pile foundation construction, is carried out grouting process, from but the soil body fully contact with pile body.On the one hand the soil body is fully contacted with pile body, before the soil body stops, higher pile body bearing capacity is provided, simultaneously, slip casting makes the soil body obtain reinforcing, and also can increase pile body bearing capacity, strengthen simultaneously stake with between be connected.
(2), grouting behind shaft or drift lining concrete pre-stress hollow fillet triangle provided by the invention stake; Week is circular in its cross section; Interior week is the fillet triangle; Effectively raise the specific area of material, can make unit materials have bigger surface area, thereby the stake side-friction force of raising preformed pile is to improve bearing capacity of single pile.
(3), grouting behind shaft or drift lining concrete pre-stress hollow fillet triangle provided by the invention stake; Week is circular in its cross section, and interior week is the fillet triangle, and its corner is stress and eliminates circular arc; So the present invention's corner in the pile body moulding is easy to moulding, can effectively improve the pile rate.
