Pile hole top opening safety construction protection structure

Abstract

The application discloses a pile hole top opening safety construction protection structure, which comprises a foundation layer with a pile hole, a pile hole protection wall, a reinforcement in an extended state at the axial end of the pile hole protection wall, a protection cylinder A, a protection cylinder B and a connecting plate, wherein the protection cylinder A, the protection cylinder B and the connecting plate are arranged on the axial top surface of the pile hole protection wall. When the pile hole protection wall needs to be heightened, the arc eccentric block is sleeved on the reinforcement through the interval stress sleeve, and the interval is between the reinforcement and the protection cylinder A and the protection cylinder B. The connecting plate is detached from the protection cylinder A and the protection cylinder B. The protection cylinder A and the protection cylinder B are separated from the gravel layer after being close to each other through the gap. The problem that the protection cylinder is in an integral structure and cannot be detached, thereby causing the inconvenience of heightening the pile hole protection wall in the later period, is solved.

Description

Technical Field

[0001] This utility model relates to a safety protection structure for the top opening of a pile hole, belonging to the field of hole opening protection technology. Background Technology

[0002] When a gravel layer 2 needs to be laid on the foundation layer 1 at the construction site, the pile holes located within the foundation layer must be protected to prevent gravel from falling into the pile holes 11. Figure 3 As shown.

[0003] Existing pile hole protection technology (see Chinese Patent Publication No. CN116479873A) protects the pile hole by installing a protective cylinder inside the pile hole. However, the protective cylinder is an integral structure that cannot be disassembled, which makes it inconvenient to raise the pile hole wall 4 later. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a safety protection structure for the top opening of a pile hole.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a safety protection structure for the top opening of a pile hole during construction, comprising:

[0007] A foundation layer with pile holes has been formed;

[0008] The pile hole retaining wall is located inside the central pile hole, and the axial end of the pile hole retaining wall has reinforcement in a protruding state.

[0009] The protective cylinder consists of a protective cylinder A, a protective cylinder B, and a connecting plate, which are located on the top axial surface of the pile hole wall.

[0010] The retaining wall of the pile hole is made of reinforced concrete.

[0011] A gravel layer is laid on the base layer, and the gravel layer is located on the outside of the protective cylinder A and the protective cylinder B that are spliced ​​together to form a whole.

[0012] The number of connecting plates is two. The connecting plates are detachably fixed to the joint of protective cylinder A and protective cylinder B by screws. The two gaps after the protective cylinder A and protective cylinder B are joined are detachably fixedly connected by the connecting plates, so that protective cylinder A, protective cylinder B and connecting plates constitute a detachable protective cylinder.

[0013] A spacer sleeve is rotatably mounted on the reinforcement, and an arc-shaped eccentric block is mounted on the spacer sleeve. The arc-shaped eccentric block is located in the space between the reinforcement and the protective cylinder A and the protective cylinder B.

[0014] The beneficial effects of this utility model are as follows: when the pile hole retaining wall needs to be heightened, the arc-shaped eccentric block is spaced out between the reinforcement and the protective cylinder A and the protective cylinder B by the interval force sleeve. The connecting plate is removed from the protective cylinder A and the protective cylinder B. After the protective cylinder A and the protective cylinder B approach each other through the gap, they are separated from the gravel layer. This solves the problem that the protective cylinder is an integral structure and cannot be disassembled, which makes it inconvenient to heighten the pile hole retaining wall later.

[0019] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0020] like Figures 1 to 2 As shown.

[0021] This application discloses a safety protection structure for the top opening of a pile hole, comprising:

[0022] The protective cylinders A7 and B3 are detachably and fixedly connected. The protective cylinders A7 and B3 are spliced ​​on the axial top surface of the pile hole retaining wall 4. The pile hole retaining wall 4 is located inside the pile hole 11 in the foundation layer 1.

[0023] The pile hole retaining wall 4 is made of steel bars and concrete, and the reinforcement 41 of the pile hole retaining wall 4 is in the extended state.

[0024] A gravel layer 2 is laid on the base layer 1, and the gravel layer 2 is located on the outside of the protective cylinder A7 and the protective cylinder B3 that are spliced ​​together to form a whole.

[0025] It also includes two connecting plates 5, which are detachably fixed to the joint of the protective cylinder A7 and the protective cylinder B3 by screws. The gap after the protective cylinder A7 and the protective cylinder B3 are joined is detachably fixed and connected by the connecting plates 5, so that the protective cylinder A7, the protective cylinder B3 and the connecting plates 5 constitute a detachable protective cylinder.

[0026] A spacer sleeve 6 is rotatably mounted on the reinforcing bar 41. An arc-shaped eccentric block 61 is mounted on the spacer sleeve 6. The arc-shaped eccentric block 61 is located in the gap between the reinforcing bar 41 and the protective cylinders A7 and B3. When the protective cylinders A7 and B3 need to be fixedly spaced and supported by the reinforcing bar 41, the arc-shaped eccentric block 61 is inserted into the gap between the reinforcing bar 41 and the protective cylinders A7 and B3 through the spacer sleeve 6. When the protective cylinders A7 and B3 are disassembled and removed, the arc-shaped eccentric block 61 is removed from the gap between the reinforcing bar 41 and the protective cylinders A7 and B3 through the spacer sleeve 6.

[0027] Protective cylinders A7 and B3 are spliced ​​on the axial top surface of the pile hole retaining wall 4. The gravel layer 2 is located outside the protective cylinders A7 and B3. The protective cylinders A7 and B3 are detachably fixedly connected by the connecting plate 5, so that the protective cylinders A7, B3 and the connecting plate 5 form a detachable protective cylinder. When the pile hole retaining wall 4 needs to be heightened, the arc eccentric block 61 rotates out of the spacer sleeve 6 between the reinforcement 41 and the protective cylinders A7 and B3. The connecting plate 5 is removed from the protective cylinders A7 and B3. After the protective cylinders A7 and B3 approach each other through the gap, they detach from the gravel layer 2. This solves the problem that the protective cylinder is an integral structure that cannot be disassembled, which makes it inconvenient to heighten the pile hole retaining wall later.
