Abstract
The utility model relates to the technical field of building construction equipment, and discloses a pile casing device of a foundation pit support cast-in-place pile. The device comprises a pile noumenon, wherein the pile noumenon is provided with a pile body, a grout pipe is arranged in the middle of the pile noumenon, the pile body and the grout pipe are coaxial, and a steel pipe casing is arranged around the pile body. According to the pile casing device of the foundation pit support cast-in-place pile, the quality of the pile body is higher, the concrete pouring quality is high, and the production cost is lower.
Description
Technical field
The utility model relates to the technical field of construction implement device.
Background technology
Chinese invention patent number: 200910141211.6 disclose combination stiffening filling pile comprises plain concrete pile body, reinforcing cage and shaped steel skeleton; And the shaped steel skeleton is coaxial with the plain concrete pile body; The plain concrete pile body is wrapped in reinforcing cage and shaped steel skeleton; Said shaped steel skeleton comprises channel-section steel or the i iron more than, and said reinforcing cage comprises the vertical muscle that is distributed on the circumference, the ring stiffener of encircling vertical muscle and spiral stirrup; Plain concrete pile body diameter is the 400-1200 millimeter, and stake is long to be 5-25 rice; The vertical muscle of channel-section steel more than one or i iron and reinforcing cage is positioned at the tensile region of same circumference, or is positioned at reinforcing cage inside; Evenly be distributed with shear key on channel-section steel or the i iron web from top to bottom.
The bored concrete pile that supporting is used mainly adopts mud off, pore-creating, after put reinforcing cage, concreting in the hole again; Form bored concrete pile, because the influence of unfavorable geology, the phenomenon of caving in the bored concrete pile hole is very general; Clear hole difficulty is big; Fullness coefficient increases (fullness coefficient that has reaches more than 2), cause the concrete waste, and the bored concrete pile physical dimension after the moulding is poor.
The utility model content
The utility model purpose aims to provide a kind of pattern foundation pit supporting structure castinplace pile casing device, and this pattern foundation pit supporting structure castinplace pile casing device makes the mass ratio of pile body higher, and concrete pouring quality is high, and cost of production is lower.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of pattern foundation pit supporting structure castinplace pile casing device; Comprise a body, said stake body is provided with pile body, in the middle of said stake body, is provided with grout pipe; Said pile body and grout pipe are same axles, and said pile body periphery is provided with the steel pipe casing.
Said a kind of pattern foundation pit supporting structure castinplace pile casing device, its steel pipe casing upper end is provided with steel pipe casing lifting mouth.
Said a kind of pattern foundation pit supporting structure castinplace pile casing device, its grout pipe is the steel pipe grout pipe.
Said a kind of pattern foundation pit supporting structure castinplace pile casing device, its pile body is concrete pile body.
This pattern foundation pit supporting structure castinplace pile casing device makes the mass ratio of pile body higher, and concrete pouring quality is high, and cost of production is lower.Adopt steel pipe to be a casing, in the hole, put into earlier steel pipe, concreting in steel pipe again, pile quality is guaranteed, and the concreting consumption is controlled easily.Can accurately control concrete amount, pouring quality is guaranteed.Steel pipe can replace reinforcing bar, and stress is clear and definite, and physical dimension guarantees easily.This device is applicable to the bored concrete pile of foundation pit supporting project, the construction of the serious soil layer geology in hole that is specially adapted to collapse.
