Abstract
The utility model discloses a recyclable steel casing which comprises an inner casing, an outer casing, a U-shaped bracket and a hoop; the bottom side of the inner casing is turned out, and the bottom of the outer casing is arranged in the turn-out slot of the inner casing; the U-shaped bracket is arranged at the bottom of the inner casing, and the outer side of the U-shaped bracket is provided with the hoop. After the construction of a pile foundation is over, the outer casing can be directly pulled out, and the casing can be reused, so that resources are saved, the structure is simple, and the stability is good.
Description
Technical field
The utility model relates to pile foundation construction equipment in the water in the engineerings such as bridge, is specifically related to a kind of recyclable steel casing.
Background technology
In the process of carrying out hand excavated pile, because the soil property instability, so the construction reinforced bar concrete guard wall exists big difficulty to adopt the retaining wall of steel that the hole stake is protected, construction speed and safety are avoided influencing in the hole that prevents from collapsing.The steel casing can be stablized hole wall, can also isolate surface water, starter, spud pile position, protection operation original ground etc.After the sclerosis of drilled pile inner concrete, the steel casing should be extracted, with recycling steel casing.But the vibrations that produce in extracting the construction of steel casing and huge mechanical external force can produce drilled pile and destroy, and job site complexity, so that be difficult to implement, cause pile foundation construction to finish after, drilled pile steel casing be can't directly extract, very big material and the wasting of resources caused.
The utility model content
The technical problem that solves:At the deficiency that existing steel casing design exists, the utility model provides a kind of recyclable steel casing, adopts two casing structures, and interior casing reclaims outer casing as the separation layer of outer casing.
Technical scheme:The utility model provides a kind of recyclable steel casing, comprises interior casing, outer casing, U-shaped carriage and anchor ear; Turn up in interior casing base, casing turned up in the groove in outer casing bottom was held on; Casing bottom in U-shaped carriage is located at, the outside is provided with anchor ear one.
Beneficial effect:Because the utility model has adopted technique scheme, the U-shaped carriage outside is provided with anchor ear one, and anchor ear integral body is stressed, on the one hand for clamping outer casing, and not slippage of casing in when guaranteeing lifting, U-shaped carriage difficult deformation and interior casing are stressed evenly when guaranteeing on the other hand that pile foundation is squeezed into; Pile foundation construction can directly be extracted outer casing and reuse after finishing, and is simple in structure, good stability.
Description of drawings
Fig. 1 is the plan structure figure of recyclable steel casing;
Fig. 2 is the A-A sectional view;
Among the figure, casing in the 1-, the outer casing of 2-, 3-U type carriage, 4-anchor ear.
The specific embodiment
Embodiment 1
A kind of recyclable steel casing of the utility model, casing 1 in comprising, outer casing 2, U-shaped carriage 3 and anchor ear 4; Turn up in interior casing 1 base, casing 1 turned up in the groove in outer casing 2 bottoms were held on; U-shaped carriage 3 is located at interior casing 1 bottom, and the outside is provided with anchor ear 4 one.
Embodiment 2
During use, at first adopt three folder hammers vertically evenly to knock outer casing 2 upper ends, interior casing 1 moves down simultaneously with outer casing 2; After treating that depth of drive reaches requirement, placing of concrete in the inside casing 1; After treating that the pile foundation concrete construction is finished, concrete strength reaches at 80% o'clock, outer casing 2 can be transferred to; Sustained vibration is about three minutes in position for outer casing 2 before extracting, and hammering into shape vertically upward with three folders then, dial-out gets final product.Vibrating hammer is selected the vibrating hammer of a high grade when squeezing into for use when pulling out casing, also must select three folder hammers simultaneously for use.
