The technical scheme of the utility model is as follows: a steel pile casing device for preventing a reinforcement cage from floating comprises a steel pile casing body, a steel bar circular ring, positioning angle steel and a plurality of fixed combinations; the steel pile casing body and the steel bar circular ring are coaxially arranged, and the steel bar circular ring is sleeved on the steel pile casing body; one end of the positioning angle steel is fixedly connected with the outer wall of the steel pile casing body, the other end of the positioning angle steel is fixedly connected with the inner wall of the steel bar circular ring, and the steel bar circular ring is fixed on the outer wall of the steel pile casing body through the positioning angle steel; any one of the fixing combinations comprises a national standard D-shaped shackle, a turnbuckle and a hollow round tube, wherein the O-shaped end of the turnbuckle is hinged on the steel bar round ring through the D-shaped shackle.
Further: the hollow round tube is any one of a cast iron tube, a stainless steel tube or a scaffold steel tube.
Further: the number of the positioning angle steel is four, the four positioning angle steel are uniformly distributed along the circumferential direction of the steel bar circular ring, and the steel bar circular ring is promoted to be divided into four fixed sections by the four positioning angle steel along the circumferential direction of the steel bar circular ring.
Further: each fixed section is provided with a fixed combination.
The beneficial effect of this scheme:
The scheme provides a simple structure's steel protects a section of thick bamboo device, and this steel protects a section of thick bamboo device and includes fixed mounting reinforcing bar ring on steel protects a section of thick bamboo body to through the articulated turnbuckle of D type shackle on the reinforcing bar ring. The hollow round tube is fixed through the C-shaped end of the turnbuckle, and is sleeved on the longitudinal ribs of the reinforcement cage by the hollow round tube and is abutted to the top row of reinforcement ribs of the reinforcement cage. The whole length of the turnbuckle is adjusted to compress or loosen the hollow round tube: the whole turnbuckle is lengthened, namely the hollow round tube is loosened; the turnbuckle is wholly shortened to downwards compress the hollow round tube. The hollow round pipe is pressed down to the longitudinal bars of the reinforcement cage, so that the reinforcement cage does not float up when the pile body concrete is poured. The whole structure is simple, the operation training of field construction personnel is very suitable, and the whole cost is very low.
Because the single longitudinal rib is vertically pressed, even if a plurality of fixing combinations are arranged, the guide pipe in pile body concrete pouring can not be blocked or interfered, the construction is facilitated, and the pile body concrete pouring device is very suitable for being used on the same type of construction site.

Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
As shown in fig. 1, 2 and 3, the utility model discloses a steel pile casing device for preventing a reinforcement cage from floating up, which comprises a steel pile casing body 1, wherein a reinforcement ring 7 is arranged outside the steel pile casing body 1, and the reinforcement ring 7 and the steel pile casing body 1 are coaxially arranged. The inner wall of the steel bar circular ring 7 is welded with the outer wall of the steel casing body 1 through the positioning angle steel 6. As shown in fig. 3, two ends of the positioning angle steel 6 are respectively welded with the inner wall of the steel bar circular ring 7 and the outer wall of the steel pile casing body 1, and the steel bar circular ring 7 is fixed on the steel pile casing body 1 by using the positioning angle steel 6.
In this embodiment, four positioning angle steels 6 are welded on the outer wall of the single steel casing body 1, and the four positioning angle steels 6 are uniformly distributed along the circumferential direction of the steel bar circular ring 7, so that the steel bar circular ring 7 is divided into four fixing sections 71 along the circumferential direction of the steel bar circular ring 7. A fixed combination is provided on each fixed section 71 of the rebar ring 7. The number of the fixed combinations is selected and set according to the number of the longitudinal ribs 22 of the reinforcement cage 2. For the rotary digging pile with the depth exceeding 10 meters, a fixed combination is not required to be arranged on the longitudinal ribs 22 of each reinforcement cage 2. This is a reasonable adjustment based on the construction requirements.
For the design of the fixing combinations, each fixing combination comprises a national standard D-shaped shackle 3, a turnbuckle 4 and a hollow round tube 5. The hollow round tube 5 can be a cast iron tube, a stainless steel tube or a scaffold steel tube, and the length of the hollow round tube 5 is determined according to the distance between the top row reinforcing rib steel bars 21 of the steel reinforcement cage 2 and the C-shaped end of the turnbuckle 4. As shown in fig. 2, the O-shaped end 42 of the turnbuckle 4 is hinged to the reinforcing bar ring 7 by the D-shackle 3, and the C-shaped end 41 of the turnbuckle 4 is turned down and inserted into the upper port of the hollow circular tube 5. The lower port of the hollow round tube 5 is downwards sleeved on a single longitudinal rib 22 of the reinforcement cage 2, and the lower port of the hollow round tube 5 is abutted on a top row of reinforcement rib reinforcements 21 of the reinforcement cage 2. It should be noted that: the top row of reinforcing ribs 22 are typically welded in the reinforcement cage, with each longitudinal rib 22 being welded, in this case to the top-most turn.
When the reinforcement cage 2 needs to be fixed, the middle part of the turnbuckle 4 is screwed after the installation, and the length of the whole turnbuckle 4 is shortened. The hollow round tube 5 is pressed downwards under the pulling force of the turnbuckle 4 so as to fix the reinforcement cage 2 and prevent the reinforcement cage 2 from floating upwards when pile body concrete is poured. After pile body concrete pouring is completed, the reinforcement cage 2 is pressed by the pile body concrete and cannot float upwards. The turnbuckle 4 can be loosened to extend the turnbuckle 4, the C-shaped end 41 of the turnbuckle 4 is driven to be separated from the hollow circular tube 5, and then the hollow circular tube 5 is pulled out from the pile body concrete. The whole operation process is very simple.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
