Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figures 1 to 4, a kind of bottom has the sealing centrifugal supporting square pile space enclosing structure of positioning and guiding groove, comprise the centrifugal supporting square pile 1 of sealing, its both sides are respectively equipped with positioning and guiding groove 11, be provided with positioning and guiding chase mortise 12 in the positioning and guiding groove 11 of a wherein side bottom, the bottom of another side is hypotenuse 13.The positioning and guiding groove 11 of above-mentioned sealing offcenter squared pile 1 is arranged in (see figure 2) on relative dual-side in non-corner, is arranged in (see figure 4) in two adjacent side around the corner.
The length of positioning and guiding chase mortise 12 needs to carry out corresponding adjustment according to design, is generally 1/5 to 1/2 of sealing centrifugal supporting square pile 1 length.Form piling wall (see figure 3) by the occlusion of positioning and guiding groove 11 and positioning and guiding chase mortise 12 during construction, so both improve the overall structure performance of piling wall, constraint guide effect can be played in piling process again.The cavity 14 of positioning and guiding groove 11 formation on adjacent sealing centrifugal supporting square pile 1 top, its inside is marked with cement grout, can play water seepage prevention effect after cement grout solidifies.
This sealing centrifugal supporting square pile 1 is the concrete precast pile of built-in arrangement of reinforcement, and its prefab form is special, in template, usually arranges counterweight to balance the centrifugal angular force produced in irregularly shaped sealing centrifugal supporting square pile 1 high-speed rotation.This water centrifugal supporting square pile 1 be a kind of can batch production, assemblingization foundation pit supporting construction.
The concrete that the centrifugal supporting square pile 1 of sealing adopts is strong concrete, and its intensity is not less than C60.
The cross section of the built-in arrangement of reinforcement 15 of sealing centrifugal supporting square pile 1 is irregularly shaped, volume cage and manual colligation is automatically needed to combine, the material of arrangement of reinforcement 15 is high-strength prestress rod iron, and its stretching force, within lifting does not produce the tension stress in crack, adopts pre-tensioning system construction usually.
As required, the outside of the centrifugal supporting square pile 1 of sealing, can arrange agitation pile water-stop curtain 2 or TRD water-stop curtain 3, see Fig. 7 and Fig. 8; Also by the above-mentioned sealing centrifugal supporting square pile space enclosing structure with positioning and guiding groove, can insert in churned pile wall or in TRD cement soil wall, see Fig. 9 and 10.
Adopt the above-mentioned sealing centrifugal supporting square pile space enclosing structure with positioning and guiding groove, after piling wall of having constructed, the cavity 14 that positioning and guiding groove 11 between stake is formed is rinsed and injects cement grout, after solidifying, plays water seepage prevention effect.Its construction method concrete steps are as follows:
1) levelling of the land;
2) surveying setting-out;
3) excavate guide channel and mark square pile insertion position;
4) heavy initial stake;
5) pitching pile, adopts two two-way check verticality of transit;
6) pile sinking;
7) move guiding trestle and continue construction;
8) cavity that groove between stake is formed is rinsed and injects cement grout;
9) secure ID is carried out.
The adjacent close slotting body of wall of square pile that the present embodiment adopts, due to the interlocking of positioning and guiding chase mortise and positioning and guiding groove between the stake of bottom, improve whole space enclosing structure bending resistance and the structural performance of body of wall, between the stake of top, positioning and guiding groove is formed in cavity and injects cement grout, plays water seepage prevention effect.
