Abstract
The utility model relates to a pile toe assembly for construction of an injection-compression molding an earth-rock composite pile. The structure comprises a pile disk with an grouting hole, and a pile toe arranged under the pile disk, and the key points lie in that the pile toe is a hollow conical structure formed by enclosing a group of pile toe flaps; each pile toe flap is respectively hinged with the pile disk by means of a pivot shaft; the hollow conical structure is internally provided therein with a capsule communicated with the grouting hole; and the capsule is fixed by a connecting piece arranged on the pile disk. By the scheme disclosed by the utility model, the pile disk of the pile toe is provided with the grouting hole and a reinforcing rib assembly; the grouting hole is provided with threads; an grouting tube and the grouting hole are in threaded connection, so as to ensure that the grouting tube is steady and does not float upwards when cement concrete is injection-compressed into the grouting tube, thus ensuring the pile quality. In grouting, as a positioning disk of the pile toe is provided with the reinforcing rib assembly, cement forms one piece with the reinforcing rib after solidification; and as the pile disk is provided with the highly-elastic capsule fixed by the positioning disk, with the increasing of grouting pressure and the injection of paste, the closed pile flaps are pushed to be opened, so that the pile flaps 'bloom', and an enlarged pile base is firstly formed at the pile base, and thus the pile toe is firmly fixed into an earth foundation.
Description
Technical field
The utility model belongs to injection moulding soil stone composite pile construction field; Relate to the pile crown of using in the work progress; Specifically injection moulding soil stone composite pile is pressed when annotating concrete, is the sharp assembly of a kind of working stake of injection-compression molding soil stone composite pile of avoiding a steel pipe come-up difficult problem to design.
Background technology
In the construction of injection-compression molding soil stone composite pile, pressing steel pipe come-up when pressing the cementing concrete in the pipe, the dependence top workpiece of exerting pressure huge to annotating, difficult installation, efficiency of construction is low.
Summary of the invention
The utility model has designed the sharp assembly of a kind of working stake of injection-compression molding soil stone composite pile in order to solve in the composite pile work progress Grouting Pipe come-up difficult problem, and body is firmly non-rising when having guaranteed that construction is pressed the cementing concrete in Grouting Pipe, thereby guarantees pile quality.
The technical scheme that the utility model adopts is: the sharp assembly of a kind of working stake of injection-compression molding soil stone composite pile; Comprise the stake dish that has injected hole in the structure and be arranged on the stake point that the below is coiled in stake; Key is: described stake point is to crowd around the conical hollow structure that become by one group of stake cusp; Each cusp is hinged with the stake dish by hinge respectively, and the conical hollow inside configuration is provided with the capsule that is communicated with injected hole, and capsule is fixed by the connector that is arranged on the stake dish.
The beneficial effect of the utility model is: this programme adopts all steel stake point assembly, is provided with injected hole and reinforcing rib assembly on the stake dish in stake point assembly.The injected hole place is provided with screw thread, and Grouting Pipe is threaded with injected hole, and Grouting Pipe is firmly non-rising when having guaranteed in Grouting Pipe, to press the cementing concrete, thereby guarantees pile quality.During slip casting, at first be cement concrete to be injected in the stake point, the reinforcing rib assembly arranged below the stake dish of stake point through small-sized Grouting Pipe; Be consolidated into one with reinforcing rib after the cement solidification, the stake dish is provided with by the fixing high resiliency capsule of positioning disk, along with grouting pressure increases and the slurry injection; Push the stake cusp that closes up open; A cusp " is bloomed ", at the bottom of stake, at first form one and enlarge the stake end, firm being fixed in the soil matrix of stake point.The sharp assembly of stake is pressed the integral body of pipe for welding together with notes, thereby solves when pressing pipe to press the cementing concrete to notes, annotates pressure pipe come-up problem.

The specific embodiment
The sharp assembly of a kind of working stake of injection-compression molding soil stone composite pile; Comprise the stake dish 1 that has injected hole 1-1 in the structure and be arranged on the stake point 2 that 1 below is coiled in stake; Importantly: described stake point 2 is to crowd around the conical hollow structure that become by one group of stake cusp 2-1; Each cusp 2-1 is hinged with stake dish 1 by hinge 8 respectively, and the conical hollow inside configuration is provided with the capsule 3 that is communicated with injected hole 1-1, and capsule 3 is fixed by the connector that is arranged on the stake dish 1.In work progress, along with grouting pressure increases and the slurry injection, high resiliency capsule 3 enlarges, and to push the stake cusp that closes up open, a cusp " is bloomed ", at the bottom of stake, at first forms one and enlarges the stake end, firm being fixed in the cement concrete of point.
For fixing capsule 3 better, to avoid capsule 3 landings in the slip casting process, in the present technique scheme, comprise a circular orientation dish 6 that is fixed on stake dish 1 lower surface in the structure of described connector, capsule 3 is sleeved on the positioning disk 6 and by clip and fixes.
Described stake dish 1 lower surface also is provided with one group of reinforcing rib 4 assembly.Reinforcing rib 4 is cemented in the cement concrete, makes the stake end and pile foundation behind the pile firmer.
Described stake dish 1 is provided with one group of groove, and a cusp 2-1 is provided with boss 2-2, and boss 2-2 pegs graft with the groove on the stake dish 1 by hinge 8 and locatees.
The quantity of described stake cusp 2-1 is no less than 3.
The upper surface of described boss 2-2 is a lozenges.Consider that according to mechanical characteristic boss 2-2 adopts lozenges, in the process of piling, the sharp assembly of stake is difficult for scattering, so that the grouting operation of postorder.
In the specific implementation; Choose the stake dish 1 that meets diameter according to annotating pressure pipe 5 diameters; Make the injected hole 1-1 that matches with Grouting Pipe 7 in central authorities; Coil 1 lower surface in stake and weld annular positioning disk 6, on stake dish 1, weld reinforcing rib 4 assemblies afterwards, capsule 3 is sleeved on the positioning disk 6 and by clip fixes.Insert Grouting Pipe in the injected hole 1-1 again and by being threaded.If notes are pressed pipe 5 external diameter 19cm, choose the stake dish 1 of diameter 20cm, thickness of slab 1.5cm is at the injected hole 1-1 of middle position brill Φ 49mm, threading, round steel T-shaped reinforcing rib 4 assemblies of five Φ 12 of welding.Weld high 30mm, Φ 150mm twines the positioning disk 6 of solid capsule 3 usefulness, and capsule 3 is sleeved on the positioning disk 6, makes capsule 3 be communicated with injected hole 1-1, fix by clip afterwards.During construction, press stake dish 1 pipe 5 to be pressed into soil matrix with annotating, be pressed into cement concrete to small-sized Grouting Pipe 7, after mud jacking was accomplished, left-hand thread withdrawed from small-sized Grouting Pipe 7, after waiting to solidify, pressed pipe 5 cementing concretes to annotating.
