It includes foundation construction, main structure construction, roofing construction, and decoration construction.

[0003] In the construction of bored piles for foundation engineering, the connection of the reinforcing cages has always been a problem affecting the construction progress and quality. The connection time generally accounts for 80% of the total cage lowering time.

In sleeve connections, quality defects such as steel bar misalignment, thread damage, and inadequate tightening of the connected steel bars may occur. Adjusting and correcting steel bar misalignment also affects the connection speed of the reinforcing cage; the occurrence of quality defects also relates to the bending and shear resistance of the entire retaining pile, thus affecting the safety of the entire retaining structure.

[0056] The following points should be followed for management and control during construction:

[0057] 1. Threading process quality management

[0058] (1) Organize construction personnel to participate in training and provide technical guidance. Experienced technicians will give presentations. All team leaders and operators will participate and conduct assessments based on on-site operations. Those who perform well will be recognized.

[0059] (2) Before processing, since some steel bar ends do not meet the processing requirements, a cutting machine is used to cut off the uneven parts of the steel bar ends to achieve the requirement of flat ends.

[0060] (3) The rebar joints are made with one side fully threaded and the other side partially threaded. After processing, each joint is inspected and any unqualified threads are reprocessed. The inspection items are appearance cleanliness, thread diameter, and number of thread turns.

[0061] (4) Inspection method: Use a ring gauge to check the thread length. If the error is within the range, it is qualified. At the same time, use a thread no-go gauge to check the thread size. If the go gauge can be screwed in and the no-go gauge cannot be screwed in completely, it is qualified. The screw-in length of the ring no-go gauge should not exceed 9mm. If it is unqualified, the thread needs to be re-machined.

[0062] 2. Reinforcing bar protection at joint 5 of the reinforcing cage

[0063] (1) The finished steel cage 5 is stored on a flat and dry site. When storing, a sign is hung on each section of steel cage 5 to indicate the pile number, section number, etc., and the thread ends are protected.

[0064] (2) To address the deformation of the reinforcing bars caused by the joints dragging on the ground and being pressed or collided during the hoisting of the reinforcing cage 5, an auxiliary trolley for hoisting the reinforcing cage was made using materials such as angle steel, reinforcing bars, and pulleys.

[0065] (3) Place the steel cage 5 into the steel cage hoisting auxiliary trolley and lock the steel cage 5 with clamps to prevent the steel cage 5 from being dragged on the ground and causing the steel bars to deform.

[0066] 3. Reinforcing cage pre-assembly technology

[0067] (1) First, cut the first section of the steel cage 5 of the pile according to the design drawings and specifications, and weld the first section of the steel cage 5.

[0068] (2) Before transporting the completed first section of the steel cage 5 to the first suitable position of the steel cage support 4 using the flatbed trolley 3 of this utility model, place the wooden board on the flatbed trolley 3 and the steel cage support 4, and then push and roll the first section of the steel cage 5 to the first suitable position of the steel cage support 4 using the wooden board.

[0069] (3) For the joint position of the first section of the steel cage 5, measure the size of the steel bars of the second section of the steel cage 5 and cut them into pieces.

[0070] (4) Before transporting the completed second section of the steel cage 5 to the second suitable position of the steel cage support 4 using the flatbed trolley 3 of this utility model, the second suitable position is located to the right of the first suitable position. Place the wooden board on the flatbed trolley 3 and the steel cage support 4, and then push and roll the second section of the steel cage 5 to the second suitable position of the steel cage support 4 using the wooden board.

[0071] (5) The main reinforcement joints of the first section of the steel cage 5 and the second section of the steel cage 5 must be tightly fitted together without any gaps, and then the straight threaded sleeve is screwed on.

[0072] (6) Mark the first steel bar of the two steel cages 5 to facilitate finding the corresponding joint quickly during formal assembly.

[0073] (7) The steel cage 5 of the entire pile is completed according to the splicing method of the first steel bar.

[0074] Therefore, by adopting this utility model, precise positioning is ensured through pre-assembly technology. A tool-type track trolley, i.e. a flatbed trolley, is used to simulate the connection before the formal installation of the steel cage. The connection joints are numbered, and then connected according to the numbers. This ensures construction quality and improves the connection quality of the steel cage.

[0075] This utility model features a rationally designed structure that allows for on-site fabrication using locally sourced materials. It fully leverages the advantages of mechanization and simplicity, improving construction efficiency and ensuring the quality of the rebar cage sleeve connection. This device enables precise pre-assembly of the rebar cage before formal connection, correcting any misalignment of the main reinforcing bars in the pre-connection process. Pre-assembly also eliminates errors such as misalignment of the threaded sleeve top screws between the main reinforcing bars, preventing damage to the threads of the main reinforcing bars (sleeves) during the final connection. The device is simple to manufacture, easy to operate, and the process is readily mastered, requiring minimal skill from operators. It is reusable and economical in rebar cage sleeve connection projects for cast-in-place piles.

[0076] This invention relates to a pre-assembly operation of the steel cage sleeve before connecting the reinforcing cage sleeve in cast-in-place piles, ensuring the construction quality and efficiency of the on-site steel cage sleeve connection. This construction device is characterized by its speed, efficiency, ease of operation, and high connection quality, making it extremely convenient for on-site construction and improving the quality and efficiency of the steel cage sleeve connection in cast-in-place piles. It can be widely applied to the construction of steel cage sleeve connections during cast-in-place pile construction.

[0077] In summary, the pre-assembly construction device for connecting the reinforcing cage sleeve of the bored pile can improve the docking speed and quality of the reinforcing cage sleeve connection, thereby ensuring the construction quality of the entire retaining pile. It has an ingenious design, simple structure, easy manufacturing, and low manufacturing cost, making it suitable for large-scale promotion and application.

[0078] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
