Among them, prestressed high-strength concrete pipe piles (PHC pipe piles) are hollow cylindrical concrete precast components made by the pre-tensioned centrifugal forming process.
[0003] Pipe piles are widely used in engineering fields including but not limited to highways, railways, tunnels, docks, etc., and bear the upper load through the combined action of side resistance and end resistance. Its construction is relatively simple, and the precast pipe piles can be mechanically pressed into the ground, and it is suitable for geological conditions such as strongly weathered rock formations, completely weathered rock formations, hard clay layers or dense sand layers.
[0004] When dealing with deeper foundations, multiple pipe piles usually need to be welded and lengthened and then driven into the ground. Before welding, the two pipe piles need to be aligned and temporarily fixed, and the butt joint misalignment deviation is detected. Only after meeting the requirements can the welding operation be started. At present, there is no unified or standard device for temporary fixing in the actual on-site construction process. Generally, workers or technicians rely on experience and visual inspection to adjust the equipment for butt joint, and after butt joint, spot welding is used for temporary fixing, and then the normal welding operation is started.

Detailed implementation mode
[0023] The present utility model will be further described in detail below in conjunction with embodiments and the accompanying drawings, but the implementation modes of the present utility model are not limited thereto.
[0024] A temporary fixing device for auxiliary butt joint of pipe piles, as Figure 1 and Figure 2 shown, includes two major parts: a clamping component and a limiting component. When installing the upper pipe pile, the clamping component is fixed to the lower pipe pile. At this time, the limiting component is located above the pipe pile and is used to limit and fix the installation of the upper pipe pile, so as to achieve a more accurate butt joint installation. After alignment, electric welding can be fixed in the middle gap of the limiting component. After the electric welding fixing is completed, the temporary fixing device is removed, and then full welding is carried out.
[0025] Among them, the clamping component includes a first clamping member 1 and a second clamping member 2. The inner sides of the first clamping member 1 and the second clamping member 2 both have semi-circular clamping openings. One ends of the first clamping member 1 and the second clamping member 2 are hinged to each other, and the other ends of the two are detachably fixed through a detachable component 3. The limiting component is composed of several limiting posts 4. The bottom ends of the limiting posts 4 are connected to the upper surfaces of the first clamping member 1 and the second clamping member 2. The inner sides of the several limiting posts 4 form a limiting installation area 5.
