Abstract
A coincidence pile used for modification of projects and a method for the file forming relate to a modified reinforcing pile for projects and a method for the file forming, the method removes the difficulties of reinforcing the original pile by increasing piles and adding loading platforms with poor performance. A longitudinal reinforced steel bar (3), a peripheral loop stirrup (4) and a peripheral loop concrete (2) are arranged around the external surface of an original pile (1) along the length of the original pile (1) to form the coincidence pile. The procedures are described as follows: first, the original pile is unloaded; second, the soil body is removed around the unloaded pile (1), and hole expansion is carried out around the original pile (1); third, the longitudinal reinforced bar (3) and the loop stirrup (4) are arranged in the holes around the original pile (1) along the length of the original pile (1); fourth, concrete (2) is poured into the holes, and the coincidence pile is formed. The present invention is applicable for the reinforcement and the modification of each pile for the pile foundation of added floors of each column. The present invention is simple, with increased efficiency, and has load bearing of the pile.
Description
Technical field
The present invention relates to the armored concrete stake and the piling method of field of civil engineering, especially engineered reinforcing stake and piling method thereof.
Background technology
At present, for the original structure of a pillar corresponding to a pile, when the load of the structure of the former stake of needs increases (when original building is increased layer), the drag deficiency of existing pile foundation plinth, not only need to reinforce the superstructure of original building, and existing reinforcing will increase a number and set up cushion cap former pile foundation is reinforced, this method construction is loaded down with trivial details, raw material increase, and overall performance is poor.
Summary of the invention
The present invention reinforces former pile foundation for the existing reinforcement means of solution will increase a number and set up cushion cap, it is loaded down with trivial details to construct, and raw material increase, the problem of overall performance difference, proposed a kind of engineered congruent pile and piling method thereof used, the concrete technical scheme that addresses the above problem is as follows:
The present invention is made of former stake, peripheral annular concrete, vertical muscle and peripheral annular stirrup, vertical muscle, peripheral annular stirrup and peripheral annular concrete along former pile length direction be located at former stake external surface around, constitute congruent pile.
The step of piling method of the present invention is as follows:
Step 1, between adjacent two posts, the bar base is set,, makes the Load Transfer of former pile load give the bar base at bar base top-pour (block) walling body;
Step 2, according to the design size of congruent pile, the soil body of the former stake periphery after the unloading is removed, to carrying out reaming around the former stake, the reaming degree of depth is the degree of depth of former stake then, and the stake bottom is enlarged size; Superimposed ring thickness is determined according to the load of improvement project needs around enlarged footing size and the stake;
Step 3, in superimposed ring cavity around the former stake after reaming, along former pile length direction will indulge muscle and ring-shaped stirrup be arranged on former stake around, form the overlapping layers cage of reinforcement;
Step 4, to step 2 with form around the former stake of superimposed cage of reinforcement concreting in the superimposed ring cavity, promptly form congruent pile of the present invention.
The present invention is applicable to that the original building to the corresponding pile of every post directly adds the strengthening reconstruction of the pile foundation of layer.Method of the present invention is easy, can improve work efficiency, saves raw material, and the overall performance of stake is good.The present invention is widely used in engineered pile foundation reinforcement engineering.
Description of drawings
Fig. 1 is the superimposed part and former stake 1 foundation length direction structure schematic diagram on congruent pile of the present invention basis, and Fig. 2 is the A-A cross-sectional view of Fig. 1.5 for widening the place in former stake 1 basis among the figure, and 6 is former pile foundation bottom, and 7 is the congruent pile basal part, and 8 is the hole that former basis is expanded.
The specific embodiment
The specific embodiment one: describe present embodiment in conjunction with Fig. 1, Fig. 2, present embodiment is made of former stake 1, peripheral annular concrete 2, vertical muscle 3 and peripheral annular stirrup 4, vertical muscle 3, peripheral annular stirrup 4 and peripheral annular concrete 2 along former stake 1 length direction be located at former stake 1 external surface around, constitute congruent pile.
The specific embodiment two: the step of present embodiment method is as follows:
Step 1, between adjacent two posts, the bar base is set,, makes the Load Transfer of former pile load give the bar base at bar base top-pour (block) walling body;
Step 2, according to the design size of congruent pile, the soil body of former stake 1 periphery after the unloading is removed, to carrying out reaming around the former stake 1, the reaming degree of depth is the degree of depth of former stake 1 then, and the stake bottom is enlarged size; Superimposed ring thickness is determined according to the load of improvement project needs around enlarged footing size and the stake;
Step 3, in superimposed ring cavity around the former stake after reaming 1, along former stake 1 length direction will indulge muscle 3 and ring-shaped stirrup 4 be arranged on former stake 1 around, form the overlapping layers cage of reinforcement;
Step 4, to step 2 with form around the former stake 1 of superimposed cage of reinforcement concreting 2 in the superimposed ring cavity, promptly form congruent pile of the present invention.
After congruent pile can effectively carry, water the body of wall that (block) built after removing adjacent center-to-center, make the congruent pile recovering bearing after the reinforcing.
Claims (2)
1. the engineered congruent pile of using, it is made of former stake (1), peripheral annular concrete (2), vertical muscle (3) and peripheral annular stirrup (4), it is characterized in that vertical muscle (3), peripheral annular stirrup (4) and peripheral annular concrete (2) along former stake (1) length direction be installed in former stake (1) external surface around, the formation congruent pile.
2. the described engineered piling method with congruent pile of claim 1 is characterized in that the step of this method is as follows:
Step 1, between adjacent two posts, the bar base is set,, makes the Load Transfer of former pile load give the bar base at bar base top-pour walling body;
Step 2, according to the design size of congruent pile, the soil body of former stake (1) periphery after the unloading is removed, then reaming is carried out in former stake (1) on every side, the reaming degree of depth is the degree of depth of former stake (1), and the stake bottom is enlarged size;
Step 3, in former stake (1) the superimposed on every side ring cavity after reaming, along former stake (1) length direction will indulge muscle (3) and ring-shaped stirrup (4) be arranged on former stake (1) around, formation overlapping layers cage of reinforcement;
Step 4, to step 2 with form fluid concrete (2) in former stake (1) superimposed ring cavity of superimposed cage of reinforcement on every side, promptly form congruent pile of the present invention.
