Description
Technical field
The present invention relates to a kind of foundation pile docking structure, especially can quickly consolidate the foundation pile quick thread form docking structure of docking。
Background technology
Pile foundation is by the power transmission rod member with certain rigidity and bending resistance of incoming for superstructure load ground, is a kind of ancient and common deep foundation form.Pile foundation is compared with other base forms, have that bearing capacity is high, it is little and uniform to deform, materials save, mechanization of building operation degree high, almost going for all kinds of geological conditions and various types of engineering construction, therefore its application in all types of industries with civil building engineering is widely.At present, reason and the difference of bearing capacity size due to some geology, generally require several foundation stake docking and form pile foundation, and foundation pile docking method mostly at the two ends of foundation pile respectively equipped with steel plate, again two block plates are welded when two foundation stakes are to be docked, thus complete docking, but this foundation pile docking calculation complex operation, time-consuming bothersome and cost is high。
Summary of the invention
For the problem overcoming existing foundation pile docking calculation complex operation, time-consuming bothersome and cost is high, the invention provides a kind of foundation pile quick thread form docking structure, this foundation pile quick thread form docking structure is simple to operate, time saving and energy saving, low cost, can realize foundation pile quickly firm docking.
The technical solution adopted for the present invention to solve the technical problems is: this foundation pile quick thread form docking structure includes the frustum of a cone, frustum annular groove, frustum grouting channel, frustum tooth, frustum grouting mouth, top foundation pile waiting, cone groove grouting mouth, cone wall alveolus, cone wall grouting channel, cone wall circular groove, frustum of a cone groove and bottom foundation pile waiting；nullThe end of foundation pile lower end waiting on top，Axially it is provided with the frustum of a cone stretching out prolongation，Frustum annular groove is laterally had on frustum of a cone wall，Axially have frustum grouting channel，This passage through frustum annular groove，Frustum grouting channel top is provided with semicircular frustum grouting mouth，The surrounding of frustum of a cone upper end is uniformly distributed spaced trapezoidal frustum tooth and frustum alveolus，The end of foundation pile upper end waiting in bottom，Axially it is provided with and mates the frustum of a cone groove coincideing with the frustum of a cone，Laterally have on the madial wall of frustum of a cone groove and mate the cone wall circular groove coincideing with frustum annular groove，Axially have and mate the cone wall grouting channel coincideing with frustum grouting channel，The top of cone wall grouting channel is provided with mates the cone groove grouting mouth coincideing with frustum grouting mouth，The surrounding of frustum of a cone groove outer upper end is evenly distributed with the cone wall alveolus docked with frustum tooth thread form，Cone wall alveolus staggers with cone wall tooth spacer；After bottom foundation pile waiting squeezes into ground, when leaving the frustum of a cone groove of exposed end on the ground, i.e. can carry out thread form and dock by foundation pile waiting with top, when docking, it is coated with quick-drying high-strength cement slurry in the inside of the frustum of a cone and the outside of frustum tooth and frustum of a cone groove and cone wall alveolus, it is quickly completed insertion docking, after having docked, the grouting mouth that docking is formed is closed by frustum grouting mouth and cone groove grouting tone, quick-drying high-strength cement slurry is poured in frustum of a cone groove, the annular wall trench that slurries are formed by frustum annular groove and cone wall circular groove docking, and the grouting channel that frustum grouting channel and cone wall grouting channel docking are formed, fill up rapidly the position, space in docking foundation pile, the most firm docking being the most i.e. capable of between foundation pile.
Presetting straight-through steel bar piece and peripheral members in concrete on the inside of the described frustum of a cone and the wall of frustum of a cone groove, to increase the frustum of a cone and the intensity of frustum of a cone groove, after making docking, foundation pile ensures to become a bulk strength.
The described frustum of a cone inserts in frustum of a cone groove, frustum annular groove and cone wall circular groove is made to align after coincideing, quick-drying high-strength cement slurry is poured into by grouting mouth to be filled in annular wall trench, after the slurry solidification of quick-drying high-strength cement, i.e. generate the fixing ring body of an annular, this ring body half is set in the frustum of a cone of top foundation pile waiting, and second half is set in the threaded circular frustum groove of bottom foundation pile waiting, therefore, it is possible to the most upper and lower foundation pile waiting is butted into for an entirety.
When the described frustum of a cone and the docking of frustum of a cone groove, frustum grouting channel with cone wall grouting channel align coincide after become together with grouting channel, by this road grouting channel, i.e. quick-drying high-strength cement slurry can be poured into frustum annular groove and bore in the annular wall trench that wall circular groove aligns formation, thus formed and firmly close pin, complete the purpose of upper and lower foundation pile waiting docking.
The effect of described frustum grouting mouth and cone groove grouting mouth is, after upper and lower foundation pile waiting docks, frustum grouting mouth and cone groove grouting mouth align to coincide and form grouting mouth, make grouting channel define the passage run through from top to bottom, this passage i.e. can lead directly to annular wall trench, the fixing ring body of formation of could being in the milk.
During the docking of described upper and lower foundation pile waiting, frustum tooth and the identical docking of cone wall alveolus, frustum alveolus and cone wall tooth coincide and dock, thus form the thread form docking between foundation pile, it is possible to the most upper and lower foundation pile waiting is butted into for an entirety.
The invention has the beneficial effects as follows: this foundation pile quick thread form docking structure is simple to operate, time saving and energy saving, low cost, foundation pile quickly firm docking can be realized.
