Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a long spiral bored pile reinforcement cage with an integrated structure. Background Art

[0002] At present, when constructing long spiral bored piles (also known as the post-insertion steel cage process) at most construction sites, the tapered mouth of the steel cage is usually formed by welding the main reinforcement on one side. When the steel cage is embedded in the concrete and the vibrating hammer is activated, the weld at the tapered mouth of the steel cage is easily detached, causing the steel cage inlet pipe to pass through the tapered mouth, and then the steel cage does not reach the designed depth. In addition, in the existing technology, there is no steel casing protection device at the top of the pile, and the verticality of the steel cage and the quality of pile positioning are difficult to control. Moreover, this traditional method requires a lot of manpower under tight construction schedules, which leads to increased costs and correspondingly increased risks, making it difficult to guarantee construction quality.

[0003] Therefore, how to provide an integrated structure long spiral bored pile reinforcement cage and its manufacturing method, and how to ensure construction quality by changing the reinforcement cage manufacturing method and applying it, has become a technical problem that technical personnel in this field urgently need to solve.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An integrated structure long spiral bored pile reinforcement cage, comprising: a steel casing protection device, and a steel pipe reinforced tapered mouth protection device connected to the steel casing protection device;

[0009] A position sensor is installed on the top of the steel casing protection device, and the position sensor is used to obtain the pile position and the steel cage position and verticality information.

[0010] In actual application, the steel casing body is welded from 3mm steel plates and is cylindrical in shape, and the steel casing body is set at the designed pile top elevation.

[0011] The ship-shaped pile diameter clamps are made of Ф8 threaded steel bars and are arranged at intervals along the vertical direction of the pile.

[0012] Specifically, the steel pipe reinforced conical mouth protection device is made of a DN100 steel pipe and has a length of 150 mm; the welding point between the steel pipe and the steel bar cone is connected by spot welding.

[0013] Compared with the prior art, the integrated structure long spiral bored pile reinforcement cage described in the utility model has the following advantages:

[0014] The utility model provides an integrated structure long spiral bored pile reinforcement cage. When in use, the ship-shaped pile diameter clamp is welded and fixed to the reinforcement cage main reinforcement of the steel casing body, and the steel casing body is arranged at the designed pile position to ensure the pile foundation point position. The verticality of the reinforcement cage insertion is received and processed by the position sensor and the information is transmitted to the pile driver or crane operator at the same time. The tapered mouth of the reinforcement cage is welded and reinforced with a steel pipe. When the reinforcement cage is implanted in the concrete and the vibrating hammer is started, the welding part of the tapered mouth of the reinforcement cage can be effectively prevented from falling off, thereby avoiding the reinforcement cage inlet pipe from passing through the tapered mouth and allowing the reinforcement cage to reach the designed depth.

It can be reused and effectively reduces construction costs, achieving the goals of safety, economy and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
