Embodiment Construction

[0017] The present invention is further illustrated below by specific examples.

[0018] like Figure 1~Figure 4 As shown, a pipe pile pile body butt joint construction method includes assembly tooling, and the tooling includes a collar 1 and a limit rod 2; wherein, the collar 1 is a band-shaped closed ring structure, and the outside of the collar 1 is connected to the limit rod The rods 2 are connected by welding, and each ferrule 1 needs to be equipped with three limit rods 2. The length of the ferrule 1 is 150 mm, and the thickness is 1.5-2 mm. One end is welded to ferrule 1, the end of limit rod 2 welded to ferrule 1 is equal to the length of the unwelded end, three limit rods 2 are evenly distributed on the outer wall of one ferrule 1 at 180 degrees, limit rod 2 and Ferrules (1) are kept parallel at all times; the following steps are also included:

[0019] Step 1. Make pairing tooling:

[0020] After the construction of the first section of pipe pile 3.1 is completed ...

Abstract

The invention particularly relates to a tubular pile body butt joint construction method. The method is characterized in that an assembly tool is involved, and further comprises the following steps that before a first section of tubular pile (3.1) is in butt joint with a second section of tubular pile (3.2) after being constructed, limiting rods (2) are welded on a hoop (1) of the outer wall of the tubular pile (3.1), then the tubular pile (3.2) is lifted for butt joint work, when the distance from the lower end part of the tubular pile (3.2) subjected to lifting to the top of the half part, not provided with the limiting rods (2), of the tubular pile (3.1) is 5 centimeters or so, the tubular pile (3.2) is pushed, so that the outer wall of the tubular pile (3.2) is tightly attached to thethree limiting rods (2) welded to the outer wall of the hoop (1), the lifted tubular pile (3.2) can be placed down, and the tubular pile (3.2) and the tubular pile (3.1) are attached to each other. Through the tool and the construction method, the butt joint work of a pile body can be quickly and efficiently completed, the butt joint accuracy is high, the operation duration can be effectively shortened, and the welding quality is improved.

Description

technical field [0001] The invention relates to the field of pipeline construction, in particular to a butt joint construction method of pipe piles. Background technique [0002] With the in-depth development of foundation and foundation engineering technology, a variety of foundation construction methods have emerged, among which the pipe pile foundation is the most commonly used foundation form. The so-called pipe pile foundation is formed by butt welding construction of multiple pipe piles The complete pile body is connected with the upper cap of the pile to form a well-stressed foundation. Before the welding construction of pipe piles and pipe piles, it is necessary to ensure that the wrong side of the upper and lower pipe piles is not more than 2mm before welding can be carried out. When two pipe piles are docked, one pipe pile needs to be hoisted by a pile machine to hover in the air. The method of manual push or pull is used to continuously and repeatedly adjust the ...
