Description

Technical Field

[0001] The present application relates to the technical field of support devices, and in particular to a support structure for a pile foundation hole wall. Background Art

[0002] Pile foundation is a common form of deep foundation used to transfer the load of a building to the ground deep underground, which usually has a higher bearing capacity than the surface soil. Pile foundation consists of a series of individual columnar components that are deep underground and can be prefabricated or cast on site. Cast-in-place piles require that concrete be poured directly into the hole after drilling a hole on site to form the pile body. After the pile foundation is drilled, the hole wall at the top is prone to collapse, so the hole wall at the top of the pile foundation needs to be reinforced.

[0003] The existing support device for the hole wall of the pile foundation is a circular steel frame structure, which cannot be disassembled, resulting in laborious handling and difficulty in transportation.

[0004] In view of this, the utility model aims to provide a detachable supporting structure for pile foundation hole wall for easy transportation. Utility Model Content

[0005] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a support structure for a pile foundation hole wall, characterized in that it includes: a plurality of wall panels arranged on the pile foundation hole wall and a support ring arranged on the inner side of the wall panels; a first screw is fixedly arranged on the wall panels, a second screw is fixedly arranged on the support ring, sleeves are arranged outside the first screw and the second screw, the first screw and the second screw are respectively inserted into the sleeve from both ends of the sleeve and are threadedly connected to the sleeve.

[0007] During the working process, multiple wall panels are fitted on the wall of the pile foundation hole. Since a supporting ring is set, the supporting ring is connected to the multiple wall panels through a first screw, a second screw, and a sleeve; after rotating the sleeve, the first screw and the second screw can extend out of the sleeve, so that the supporting ring can press the wall panel against the wall of the pile foundation hole, thereby supporting the wall of the pile foundation hole; the supporting ring and the wall panel can be disassembled for easy transportation.

[0008] Furthermore, a mounting plate is fixedly arranged at one end of the second screw rod away from the sleeve, and the mounting plate is fixedly mounted on the supporting ring by bolts.

[0009] Further, the outer wall portion of the sleeve protrudes to form a polygonal knob portion.

[0010] Furthermore, two supporting rings are arranged along the axial direction of the pile foundation.

[0011] Furthermore, the two supporting rings include a first supporting ring and a second supporting ring. A first connecting block is fixedly arranged on the first supporting ring, and a surface portion of the first connecting block is concave to form an insertion hole. A second connecting block is fixedly arranged on the second supporting ring, and a surface portion of the second connecting block is protruding to form an insertion rod, which can be inserted into the insertion hole.

[0012] Further, the side wall portion of the wall panel protrudes to form an edge portion perpendicular to the wall panel.

[0013] Furthermore, a surface portion of the edge portion is penetrated to form an insertion hole, into which a fixing nail can be inserted. The fixing nail is inserted through the insertion hole and inserted into the soil.

[0014] Furthermore, a first connecting hole is formed on the mounting plate, a second connecting hole is formed on the supporting ring, the inner wall portion of the supporting ring protrudes to form a screw head, and the bolt is inserted into the first connecting hole and the second connecting hole from the side of the first connecting hole close to the screw head.

[0015] The beneficial effects of this application are:

[0016] 1. The rotating sleeve can make the supporting ring press the wall plate against the wall of the pile foundation hole. The supporting ring and the wall plate are detachably connected for easy transportation.

[0017] 2. For pile foundation hole walls of different diameters, you only need to replace the wall panels of the corresponding diameter, saving costs.

[0018] 3. The setting of the knob portion enables the staff to use tools to rotate the sleeve when the sleeve is located in the pile foundation hole.

[0019] 4. Fixing nails can make the connection between the wall panels and the soil tighter, further improving the stability of the support structure. BRIEF DESCRIPTION OF THE DRAWINGS
