Description
Technical field
The utility model relates to a kind of precast concrete pile more particularly to a kind of precast concrete ring solid square piles.
Background technique
In recent years, with the development of economy, the architecture storey in China is higher and higher, and the vertical bearing capacity and stake to stake are scratched
More stringent requirements are proposed for degree, shearing resistance, moment of flexure, while the withdrawal resistance squeezed into stake after soil layer and rock stratum also proposed higher want
It asks.Existing precast pile technique mainly passes through between stake and soil layer on the basis of meeting the bearing capacity of stake, for withdrawal resistance
Frictional force determines, in order to increase pile body and native frictional resistance, square pile is generally processed into bamboo joint pile, i.e., in four side walls of square pile
Upper processing groove.The square pile of this kind of structure is in prefabrication process, it is necessary first to the steel reinforcement cage of square pile is placed in by bed die template and
In the rectangular die cavity that two sides side template surrounds, there is the protrusion for being used to form groove, then cover the upper mold cover board of mold in mold
And four mould templates is made to be aligned and be fixedly connected, also there is the protrusion for being used to form groove, later to entire on upper mold cover board
Concrete-pile, which box out in vibration in upper mold protrusion, to be located concrete perfusion material and forms solid ring square pile.The bamboo of this kind of structure
Section square pile has the following deficiencies: 1, production technology is complicated, needs first to fix lower template and two sides side template, then cover again
Die cap plate simultaneously carries out boxing out place plus concrete material simultaneously in upper mold protrusion in vibration by upper mold cover board and two sides side template are fixed
Remove any excess concrete；It is separated simultaneously after concrete setting reaches predetermined strength, then by upper mold cover board with the die cover plate of two sides
Take out concrete square pile；2, quality is difficult to control in the production process of the square pile, due to being boxed out by vibration in upper mold protrusion
Place adds concrete material, and concrete exhaust problem easily causes leakiness or cavity, pitted skin at upper mold groove section, when serious even
Cause the thickness of concrete pile body uneven or the major defect of steel reinforcement cage leakage.Though gravity flow concrete can solve above-mentioned quality and ask
Topic, but in same intensity grade, cost can greatly improve relatively；So though have the proposition of related ring solid square pile technology,
But market application can not be implemented on.Only scale can not be formed due to cost and complex process and mass defect in pilot stage
Change volume production just to fail.
