Abstract
The invention discloses a construction method for a cast-in-place concrete pile of a soft soil foundation with a stone layer. The construction method comprises the following steps: 1), determining the centre position of a cast-in-place reinforcement concrete pile; 2), using a vibration sunken tube method to sink the precast pile tip to the designed position, and enabling the bottom elevation of a steel sleeve to be parallel to that of the pile; 3), putting a reinforcement cage to the steel sleeve; 4), pouring concrete to the designed elevation of the pile top; and 5), waiting for 1-2 hours, pulling out the steel sleeve to form the cast-in-place reinforcement concrete pile. The construction method is simple and easy to operate, high in efficiency, convenient to control project quality, and safe and reliable, thereby the construction cost is greatly reduced, the working efficiency is improved, and manpower, material resources and financial resources are saved; moreover, the construction method is applicable to construction environments such as the soft soil foundation, regions abundant in underground water and the like.
Description
Technical field
The present invention relates to a kind of deposited reinforced concrete pile job practices, particularly relate to a kind of soft foundation concrete filling pile construction method with block stone layer.
Background technology
General deposited reinforced concrete pile adopts boring method to construct; The hole phenomenon of in soft foundation deposited reinforced concrete pile pore forming process, collapsing is very general; Concrete amount increases during pile, and fullness coefficient increases, and needs all to use steel sleeve or overlength steel sleeve; The steel sleeve distortion of block stone layer zone is very big having, and can't pass through block stone layer.Silt depth is darker in the coastal area, and the block stone layer buried depth is big, considers from construction technology and engineering cost two aspects, needs to explore the deposited reinforced concrete pile job practices that makes new advances.
Summary of the invention
The present invention provides a kind of soft foundation concrete filling pile construction method with block stone layer for solving the technical problem that exists in the known technology, and this method is convenient to the Control Engineering quality.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of soft foundation concrete filling pile construction method with block stone layer may further comprise the steps:
One) confirms the center of deposited reinforced concrete pile;
Two) adopt the vibration sinking tube method that prefabricated stake point is sunk to design attitude with steel sleeve, and make the end absolute altitude of steel sleeve concordant with stake end absolute altitude;
Three) reinforcing cage is placed in the steel sleeve;
Four) concrete perfusion to stake top design elevation;
Five) wait for 1～2 hour, extract steel sleeve, form deposited reinforced concrete pile.
Upper end one side of said steel sleeve is provided with the concrete spouting mouth, in said step 4) in, concrete pours in the steel sleeve from said concrete spouting mouth; In said step 5) in; Extract steel sleeve while vibrating, owing to make concrete more closely knit and because the extracting of steel sleeve in the vibration processes, in the stake hole, form the concrete space of sinking; Adopt the reinforced method in high-altitude to fill up sagging space, form deposited reinforced concrete pile with concrete.
In said step 3) in, reinforcing cage is to inject in the steel sleeve the hole in the middle of two vibrators.
Advantage and good effect that the present invention has are: 1) adopt the vibration sinking tube method can pass block stone layer fast; 2) adopt the reinforced concrete pile point, the heavy steel sleeve construction of combining vibration, speed of fulfiling hole is faster than other rig pore-forming; 3) reinforcing cage is installed simple; 4) the concrete fullness coefficient can be effectively controlled, and reduces construction cost; 5) the present invention is applicable to construction environments such as soft foundation and the more rich area of underground water; 6) the present invention is simple and easy to do, efficient is high, be convenient to Control Engineering quality, safe and reliable, has reduced construction cost to a great extent, has improved operating efficiency, has saved human and material resources and financial resources.

See also Fig. 1～Fig. 6, a kind of soft foundation concrete filling pile construction method with block stone layer may further comprise the steps:
One) confirms the center of deposited reinforced concrete pile 7;
Two) adopt the vibration sinking tube method that prefabricated stake point 1 usefulness steel sleeve 5 is sunk to design attitude, and make the end absolute altitude of steel sleeve 5 concordant with stake end absolute altitude;
In the present embodiment, upper end one side of said steel sleeve 5 is provided with concrete spouting mouth 5-1.Adopt walking vibrator pipe sinking cast-in-place pile machine 2, configuration DZ110kw vibrating hammer is pressed in steel sleeve 5 on the stake point 1, sinks to a hole, and steel sleeve 5 passes block stone layer 3 with stake point 1.
Three) reinforcing cage 7-1 is placed in the steel sleeve 5;
In the present embodiment, adopt autocrane 6 lifting reinforcing cage 7-1, put into steel sleeve 5 from the middle hole of two vibrators.
Four) concrete perfusion 7-2 is to a top design elevation;
In the present embodiment, field by using concrete mixing and transporting car 8 transportation concrete sevens-2 are filled into concrete seven-2 in the steel sleeve 5 from said concrete spouting mouth 5-1.
Five) wait for 1～2 hour, extract steel sleeve 5, form deposited reinforced concrete pile 7.
In the present embodiment; Steel sleeve 5 is to extract while vibrating; Extracting of concrete closely knit and steel sleeve 5 of internal cause forms the concrete space of sinking in the stake hole, and present embodiment adopts the reinforced method in high-altitude to fill up sagging space with concrete, forms deposited reinforced concrete pile 7.
Six) inspection pile quality.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
