Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, technology of the present utility model is described in further detail:
Fig. 1 is the front view of the utility model for the reinforcing cage of solution cavity geology pile;
Fig. 2 is the top view of the utility model for the reinforcing cage of solution cavity geology pile.
Detailed description of the invention
As shown in Figure 1, the reinforcing cage that the utility model is used for solution cavity geology pile comprises reinforcing cage 1, expanded metal lath 2 and nylon net bag 3, reinforcing cage 1 comprises outer wall and bottom 14, outer wall comprises contact zone 4, contact zone 4 is positioned at the middle part of described outer wall, contact zone 4 is regions that the outer wall of reinforcing cage 1 contacts with subgrade, expanded metal lath 2 is wrapped in the outer wall of reinforcing cage 1, at least one circle iron wire of the outer colligation of expanded metal lath 2, for being fixed by expanded metal lath, it is outer and by coated for the bottom 14 of expanded metal lath 2 and reinforcing cage 1 that nylon net bag 3 is set in expanded metal lath 2.
Reinforcing cage 1 comprises torus shape outer wall and bottom 14, torus shape outer wall comprises at least one longitudinal reinforcement 11, at least one reinforcing bar puts more energy into hoop 12 and spiral hoop 13, put more energy into hoop 12, longitudinal reinforcement 11 and spiral hoop 13 of reinforcing bar sets gradually from inside to outside, reinforcing bar puts more energy into hoop 12 for ring-type, and arrange along its axial spacing, longitudinal reinforcement 11 along reinforcing bar put more energy into hoop 12 radial spacing spread configuration and be overlapped on reinforcing bar and put more energy on hoop 12, spiral hoop 13 is welded on longitudinal reinforcement 11 in the shape of a spiral.Bottom 14 comprises at least one root bottom part reinforcing bar, and described bottom reinforcement bars is that latticed zigzag weld is connected on longitudinal reinforcement 11.
A part for the outer wall of reinforcing cage 1 is wrapped up by expanded metal lath 2, and expanded metal lath 2 covers contact zone 4 and respectively has the surplus of 1500-2500mm at the axial two ends of contact zone 4.Expanded metal lath 2 comprises some meshes, and width of mesh is between 1 × 1cm-3 × 3cm.When expanded metal lath 2 is installed, first determine the subgrade position of engineering pile region, then on the reinforcing cage forming engineering pile, determine the position of contact zone 4, with expanded metal lath 2, contact zone 4 is wrapped up comprehensively, and the covering surplus of 1500-2500mm will be had more at the axial two ends of contact zone 4, with galvanized wire, expanded metal lath 2 colligation is firm again, ensure not come off in the process of fluid concrete.Expanded metal lath 2 effectively can stop that the coarse aggregate in concrete leaks outside.
