Abstract
The invention relates to a construction method for deviation correction of a pile foundation by high-pressure spraying disturbance and construction equipment used in the construction method. According to the deviation correction method for the pile foundation by high-pressure spraying disturbance, soil mass (5) around a pile or near a pile tip is subjected to high-pressure spraying disturbance so that the strength of the soil mass (5) is reduced and the pile (6) sinks under the action of load, thus achieving the purpose of deviation correction of a pile foundation. The construction equipment used in the method comprises a high-pressure delivery pump (1), a pore-forming fluid director (2) and a high-pressure spraying nozzle (3), wherein the soil mass (5) is disturbed by a hydraulic monitor generated at the high-pressure spraying nozzle (3). With the invention, deviation correction construction of the pile foundation can be successfully realized, the construction quality is reliable and efficient, and the safety of an original building or a structure (7) can be ensured during the process of deviation correction construction.

E) building or the structure to the need correction carry out settlement observation, and control intensity, amplitude and the duration of the disturbance construction operation that sprays water with high pressure according to observed result;
F) size according to the correction amount determines whether needs repeating step e), until finishing Deviation Correction Construction.
Second purpose of the present invention is to provide a kind of pile foundation disturbance Deviation Correction Construction equipment that sprays water with high pressure, and this pile foundation disturbance Deviation Correction Construction equipment that sprays water with high pressure can be realized the Deviation Correction Construction of pile foundation building or structure smoothly.
This pile foundation disturbance Deviation Correction Construction equipment that sprays water with high pressure comprises that high-pressure delivery pump, pore-forming air deflector and high-pressure injection mouth three parts form, high-pressure delivery pump wherein is an equipment from water under high pressure to the high-pressure injection mouth that carry, high-pressure delivery pump is connected with water source and pore-forming air deflector, the pore-forming air deflector is connected with the high-pressure injection mouth, and the pore-forming air deflector is the equipment of the high-pressure injection mouth being delivered to the precalculated position and water under high pressure being delivered to the high-pressure injection mouth.
Disturbance method for correcting error and construction equipment can be realized the pile foundation Deviation Correction Construction smoothly because pile foundation of the present invention sprays water with high pressure, reliable construction quality, and can guarantee the safety of original building in the Deviation Correction Construction process or structure.
Description of drawings
Fig. 1 is one embodiment of the present of invention generalized section;
The specific embodiment
As one embodiment of the present of invention, main purpose is to introduce a kind of pile foundation of the present invention spray water with high pressure disturbance deviation rectification construction method and used construction equipment thereof.At first introduce a kind of pile foundation of the present invention the spray water with high pressure structure construction and the operating principle thereof of the used construction equipment of disturbance correction in conjunction with Fig. 1.As shown in Figure 1, the pile foundation of the present invention disturbance Deviation Correction Construction equipment that sprays water with high pressure comprises high-pressure delivery pump (1), pore-forming air deflector (2) is formed with high-pressure injection mouth (3) three parts, high-pressure delivery pump wherein (1) is an equipment from water under high pressure to high-pressure injection mouth (3) that carry, high-pressure delivery pump (1) is connected with water source (4) and pore-forming air deflector (2), high-pressure delivery pump (1) is suction water from water source (4), by after the pressurization water under high pressure being sent into pore-forming air deflector (2), pore-forming air deflector (2) is connected with high-pressure injection mouth (3), pore-forming air deflector (2) is the equipment of high-pressure injection mouth (3) being delivered to the precalculated position and water under high pressure being delivered to high-pressure injection mouth (3), pore-forming air deflector (2) can be Drilling machineries such as jumbolter, water under high pressure is injected its peripheral soil body (5) by high-pressure injection mouth (3), in the soil body, form giant, can cut the soil body (5), disturbance and destruction, high-pressure injection mouth (3) can be by moving, rotate or swing expansion range of disturbance, behind the soil disturbance, just can sink under the effect of pile top load by the stake (6) that the soil body supports, thereby reach disturbance correction purpose.Present embodiment introduce a kind of pile foundation of the present invention disturbance deviation rectification construction method that sprays water with high pressure with the lower part in conjunction with Fig. 1.In the first step of this disturbance method for correcting error, can determine the incline direction of building or structure (7) according to the squareness measurement of settlement observation data or built construction thing or structure (7), entered for second step then.In this step, only need according to the observational data in the first step, it is heavy to reach the correction purpose to determine the stake (6) of the little side of sedimentation urge, needs the position of short heavy stake (6) to be Deviation Correction Construction and need urge to sink to locate the position, thereby finished for second step, entered for the 3rd step.In this step, reach the character of stake (6) bottom soil on every side according to stake (6), the spray water with high pressure soil body position of disturbance of definite need, the position that needs disturbed soil can be the soil of stake (6) bottom, also can be stake (6) soil on every side, can also all carry out disturbance soil and stake (6) soil on every side of stake (6) bottom.Can take the soil body position of the definite disturbance of need spraying water with high pressure of following method, as stake (6) soil on every side the sinking of stake (6) is played conclusive effect, can be only to the disturbance of spraying water of stake (6) soil on every side, if the soil of stake (6) bottom plays conclusive effect to the sinking of stake (6), can select the disturbance of spraying water of the soil of stake (6) bottom, if the soil of stake (6) bottom all plays an important role to the sinking of stake (6) with on every side soil, then to stake (6) soil and the disturbance of all spraying water of the soil of stake (6) bottom on every side.Thereby finished for the 3rd step, entered for the 4th step.In this step, the disturbance construction of spraying water with high pressure of can utilize a part is introduced before the present embodiment pile foundation to spray water with high pressure the soil body (5) that the used construction equipment of disturbance correction determines the 3rd step, utilize water under high pressure that high-pressure injection mouth (3) sprays that on every side soil of stake (6), the soil bottom the stake (6) are carried out disturbance, cutting, destroy the structure of the soil body, reduce the intensity of the soil body.Thereby finished for the 4th step, entered for the 5th step.In this step, in the 4th process of step to the soil disturbance construction, building or structure (7) to the need correction carry out settlement observation, and spray water with high pressure intensity, amplitude and the duration of disturbance construction operation according to observed result control, settling rate as stake (6) is too fast, can reduce range of disturbance, disturbance number of times, strength of turbulence and time, too slow as the subsidence velocity of stake (6), then can increase range of disturbance, disturbance number of times, strength of turbulence and time.Thereby finished for the 5th step, entered for the 6th step.In this step, the size according to the correction amount determines whether that needs repeat the 5th step until finishing Deviation Correction Construction.Thereby finish a kind of pile foundation of the present invention disturbance deviation rectification construction method that sprays water with high pressure.
This patent includes but not limited to other job practicess of the alternative use of professional person in this area.
