Description
technical field:
The utility model relates to a kind of sectional type cavity castinplace pile.
background technology:
Cast-in-place concrete pile has that bearing capacity of single pile is large, stake is long and stake footpath flexible design, construction the advantage such as to be lacked by environment restriction and be widely used in all kinds of civil engineering, as building, bridge, harbour etc.But in application process, castinplace pile has the following disadvantages, as:
(1) pile body deadweight is excessive, loses a part of vertical bearing capacity;
(2) under the prerequisite ensureing castinplace pile safety factor, compressive strength design load when the actual use compressive stress of pile body designs much smaller than it, to such an extent as in casting process, concrete amount is too much, causes waste of material;
(3) spoir and mud is produced in construction.
summary of the invention:
The utility model provide a kind of can meet the every supporting capacity of pile foundation and durability while, reduce pile body deadweight and the sectional type cavity castinplace pile of cast-in-place pile concrete consumption.
In order to realize foregoing invention object, the utility model provides a kind of sectional type cavity castinplace pile, comprises and builds by concrete and reinforcing cage the pile body formed, and described reinforcing cage is segmentation structure, is provided with fluid injection cavity in every section of reinforcing cage.
Further design of the present utility model is:
Every section of reinforcing cage includes main muscle and stirrup, and some described main muscle surround a columned cage body, and described stirrup is around being arranged on this cage body.
Be provided with retainer ring and static line in every section of reinforcing cage, described fluid injection cavity is fixed in reinforcing cage by retainer ring and static line.
Described fluid injection cavity and reinforcing cage are coaxially arranged.
The cylinder of described fluid injection cavity to be upper and lower two ends be sphere, and upper end sphere is provided with inlet.
Described inlet is connected with valve.
Described fluid injection cavity outer circumference surface is provided with ripple groove.
The liquid injected in described fluid injection cavity is water.
The utility model utilizes fluid injection cavity to replace part concrete, while meeting the every supporting capacity of pile foundation and durability, saves cast-in-place pile concrete consumption again.Consequent beneficial effect is: reduce pile body deadweight, this decrease can be used for bearing upper load, when reaching identical vertical bearing capacity, pile body length or diameter can be reduced, reduce construction costs and pouring pile hole expense, reduce spoir and mud emission, energy-conserving and environment-protective.

detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
Please refer to Fig. 1 to Fig. 3, a kind of sectional type cavity of the utility model castinplace pile, this castinplace pile is arranged in the stake holes of job site, comprises and builds by concrete and reinforcing cage 6 pile body 5 formed.
Reinforcing cage 6 in pile body 5 adopts segmentation structure, is provided with fluid injection cavity 1 in every section of reinforcing cage 6.Every section of reinforcing cage 6 includes main muscle 61 and stirrup 62, and some main muscle 61 surround a columned cage body, and stirrup 62 is around being arranged on this cage body.Fluid injection cavity 1 is fixedly connected on the main muscle 61 of reinforcing cage 6 by retainer ring 3 and static line 4, and fluid injection cavity 1 and reinforcing cage 6 are coaxially arranged.
The cylinder of fluid injection cavity 1 to be upper and lower two ends be sphere, and upside sphere is provided with inlet, inlet is connected with valve 2.By external water pipe to water filling in fluid injection cavity 1.After water fills in fluid injection cavity 1, detach external water pipe, close valve 2, the liquid in fluid injection cavity 1 is not leaked outside.
The utility model is the frictional force increasing fluid injection cavity and fluid injection cavity surrounding concrete, is provided with some grooves 11 at the outer circumference surface higher slice of fluid injection cavity 1.
The construction method of the utility model sectional type cavity castinplace pile is: arrange the reinforcing cage that segmented has fluid injection cavity 1, transferring successively of several reinforcing cage coaxial line is mounted in the stake holes of job site, when the upper port of first paragraph reinforcing cage transfers the orifice position to job site stake holes, liquid is injected in the fluid injection cavity 1 of first paragraph reinforcing cage, and the upper port of the lower port of second segment reinforcing cage with first paragraph reinforcing cage is fixedly connected with, when then transferring second segment reinforcing cage to the upper port of second segment reinforcing cage to the orifice position of stake holes, liquid is injected in the fluid injection cavity 1 of second segment reinforcing cage, the work progress of repetition second segment reinforcing cage like this installs remaining reinforcing cage body, until the reinforcing cage of remainder is filled complete stake holes and is formed reinforcing cage stake, then to the reinforcing cage stake concreting in stake holes, until concrete covers reinforcing cage stake completely, form castinplace pile 5.
The effect that fluid injection cavity 1 in the utility model fills water increases compressive property on the one hand, reduce buoyancy on the other hand, prevent from driving reinforcing cage 6 to float in stake holes, and to prevent from breaking be ring 3 and tether 4, therefore, fluid injection cavity 1 installation site and quantity should be adjusted in advance, have ensured that the weight of reinforcing cage 6 adds it and concrete frictional force sum is greater than the buoyancy of fluid injection cavity 1 in chutable concrete, and have had certain safety margin.
Fluid injection cavity 1 two ends are sphere, to improve the compressive property of fluid injection cavity 1.The lateral grooves 11 of fluid injection cavity 1, to increase fluid injection cavity 1 and the frictional force of surrounding concrete, suppress fluid injection cavity 1 to float, and reduction is the pulling force of ring 3 and tether 4.The yardstick of fluid injection cavity 1 is determined according to techniques such as castinplace pile 5, mixed earth conduit yardstick, castinplace pile 5 mechanical requirements and making, transport, installations.Fluid injection cavity 1 is a container body, and this container body can use macromolecule polymeric material, as PVC, nylon etc. are made, also scene can be replaced to pour water by inner perfusion foaming body when making, thus raising installation effectiveness, but to ensure to be the intensity of ring 3 and tether 4, and adjust the safety preventing from floating.
After reinforcing cage 6 and fluid injection cavity 1 installation, adopt DLC or three conduit modes to carry out filling concrete, require that conduit is avoided tether 4 and transferred along space between reinforcing cage 6 and fluid injection cavity 1, and be circumferentially evenly arranged, in filling process, answer synchronization lifting.Filling concrete technique requires identical with conventional castinplace pile.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
