Abstract
The invention relates to a reinforcing method for dealing with the rupture of a pipe pile after the construction of the prestressed pipe pile. The procedures are as following: (1) the position of the rupture of the prestressed pipe pile is detected first; (2) the laitance on the inner wall of the pipe pile is cleared; (3) a reinforced skeleton frame is put into the pipe pile and the reinforced skeleton extends to the position three meters under the pipe pile from the pile top; (4) concrete under pile level is poured into the pipe pile, and the strength grade is not smaller than C30; (5) after the condensation of the concrete, the reinforced skeleton frame is led to be fixed with the reinforced steel in a cushion cap, and further the reinforced technique of the rupture of the pipe pile is finished. The reinforcing method of the invention can ensure the safety of the structure and does not affect the construction of the next working procedure; besides, the invention has the advantages of convenient construction, short constructing period, low cost and good effect.
Description
Technical field
The present invention relates to prestressing pipe pile construction method, refer in particular to the reinforcement means of this pile tube fracture of a kind of prestressing pipe pile construction post processing.
Background technology
In the pile foundation construction process, on-the-spot discovery has fractured tubular piles can utilize former stake machine to carry out piling, when finding fractured tubular piles is arranged after testing after if the stake machine is moved, can be because do not allow that a machine enters construction operation again behind the excavation of construction site, so only can take the reinforcing measure, all be to adopt the pile extension reinforcement means at present generally speaking, adopt the manually digging hole form, dig to the pile body breaking place, the epimere stake utilizes the reinforcing cage bar straightening with manually cutting, so comparatively trouble, loaded down with trivial details, and claim for eot, be unfavorable for that engineering runs smooth, and the compacted effect of stake week soil weakens, a stake Zhou Tuxiang hole intrinsic displacement can cause former stake off normal, retaining wall is subjected to displacement even avalanche, does not obviously meet the demand of current building trade.
Summary of the invention
Main purpose of the present invention is to provide the reinforcement means of this pile tube fracture of a kind of prestressing pipe pile construction post processing, its easy construction, duration weak point and effective.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The reinforcement means of this pile tube fracture of a kind of prestressing pipe pile construction post processing, step is as follows:
(1) detects the position that pile for prestressed pipe ruptures earlier;
(2) pile tube inwall laitance is removed totally;
(3) put into cage of reinforcement in pile tube, this cage of reinforcement is to extend below 3 meters of pile tube fracture from stake jack-up;
(4) concrete below the pouring stake top mark height in pile tube again, its strength grade is not less than C
30
(5) after concrete condenses, the reinforcing bar in above-mentioned cage of reinforcement and the cushion cap is fixed, and then finished the reinforcement process of pile tube fracture.
Adopt inwall brushing cement paste or methods such as concrete interface agent or slightly expanded concrete to remove in above-mentioned steps (2).
Cage of reinforcement in above-mentioned steps (3) is welded by vertical fixedly reinforcing bar and crosswise fixed reinforcing bar, is positioned at vertical fixedly reinforcing bar bottom welding one undersized in the supporting plate of pile tube internal diameter.It is above-mentioned that vertically fixedly reinforcing bar, crosswise fixed reinforcing bar are evenly arranged along the pile tube circumference.
Between interlocking, above-mentioned vertical fixedly reinforcing bar, crosswise fixed reinforcing bar be provided with the stirrup of an affixed usefulness.
Above-mentioned supporting plate is a steel plate, and its thickness is 4～5mm.
The present invention's advantage is to utilize cage of reinforcement to pour into strength grade C in back below 3 meters from the stake tip cutting to the pile tube fracture
30The scheme of above concrete, it can guarantee structural safety, does not influence the subsequent processing construction, and easy construction, duration are short, effective.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further described.
As shown in Figure 1 and Figure 2, the reinforcement means of this pile tube fracture of a kind of prestressing pipe pile construction post processing, its step is as follows:
(1) detect the position a that pile for prestressed pipe 1 ruptures earlier, for example the degree of depth of ordering at a is h
1Place's fracture; Wherein detecting can be to adopt high or low deformation dynamic inspection method to carry out.
(2) pile tube 1 inwall laitance is removed totally, it adopts inwall brushing cement paste or methods such as concrete interface agent or slightly expanded concrete to remove, to improve the globality of follow-up perfusion concrete and tubular pile body concrete.
(3) prepare complex root cage of reinforcement 2, its reinforcing bar 2 whole heights calculate according to the position a of pile tube fracture, as the degree of depth h according to above-mentioned fracture position a
1If meter is cage of reinforcement 2 whole height h
2, this h so
2Be more than or equal to h
1+ h
3, h
3More than or equal to 3 meters; It is welded by vertical fixedly reinforcing bar 21 and crosswise fixed reinforcing bar 22, is positioned at vertical fixedly reinforcing bar 21 bottoms and welds the supporting plate 23 of a undersized in pile tube 1 internal diameter.It is above-mentioned that vertically fixedly reinforcing bar 21, crosswise fixed reinforcing bar 22 are evenly arranged along pile tube 1 circumference, for further vertically fixedly reinforcing bar 21, crosswise fixed reinforcing bar 22 are affixed with above-mentioned, between it is staggered, be provided with a stirrup 24, wherein vertically fixedly reinforcing bar select 6 Φ, 20 model reinforcing bars for use, and crosswise fixed reinforcing bar 22 is selected the reinforcing bar of 3 Φ, 10 models for use, and stirrup 24 is selected Φ 8@200 arrangement of reinforcement for use.Above-mentioned supporting plate 23 is a steel plate, and its thickness is 4～5mm.
(4) put into above-mentioned cage of reinforcement 2 in pile tube 1, this cage of reinforcement 2 is to extend below 3 meters of pile tube 1 fracture a from stake top 11.Certainly this top is to imbed the degree of depth in the cushion cap 3.
(5) concrete 4 below the pouring stake top mark height in pile tube 1 again, its strength grade is not less than C
30
(6) after concrete 4 condenses, above-mentioned reinforcing bar 2 and the reinforcing bar in the cushion cap are fixed, and then finished the reinforcement process of pile tube 1 fracture.
The inventor utilizes said method to carry out the construction of tens case histories, all attain the results expected, also obtained the consistent approval of Construction unit, designing unit, quality supervision and supervisor and certainly, think that this reinforcing method is simple, convenient, practical, cost is low, do not influence the subsequent processing construction, be other reinforcing method incomparable advantage, stronger economic benefit and social benefit are arranged.
After design focal point of the present invention is its prestressing pipe pile construction, when finding fractured tubular piles after testing after promptly piling machinery is withdrawn from the arena, utilize cage of reinforcement to pour into strength grade C in back below 3 meters from the stake tip cutting to the pile tube fracture
30The scheme of above concrete, it can guarantee structural safety, and easy construction, the duration is short, cost is low, effective.
The above, it only is structure preferred embodiment of the present invention, be not that technical scope of the present invention is imposed any restrictions, so every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any trickle modification, equivalent variations and modification that above embodiment did.
