Description

Technical Field

[0001] This utility model relates to the field of hollow pile technology in civil engineering, and in particular to a hollow pile for civil engineering. Background Technology

[0002] Hollow piles, also known as hollow pipe piles, are tubular structures with internal cavities. As a foundation treatment method, pile foundations are effective in controlling the amount and rate of settlement of foundations in deep soft soil areas, as well as reducing foundation vibrations caused by superloads.

[0003] The existing hollow piles have the following shortcomings in use:

[0004] When two hollow piles are spliced ​​and installed on site, the existing hollow piles are placed on top of another hollow column by hoisting and additional positioning tools are installed to position the two hollow piles. Then they are welded together. After welding, the positioning tools are removed. The whole positioning process is relatively complicated and inefficient. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing hollow piles. When two hollow piles are spliced ​​and installed on site, the hollow pile is placed on top of another hollow column by hoisting and additional positioning tools are installed to position the two hollow piles. Then, they are welded together. After welding, the positioning tools are removed. The whole positioning process is relatively complicated and inefficient. Therefore, this utility model proposes a hollow pile for civil engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hollow pile for civil engineering includes two hollow pile bodies, and the inner wall of each hollow pile body is fixedly provided with a plurality of reinforcing steel bars for strengthening the hollow pile body.

[0008] The positioning mechanism is installed on the hollow pile body and is used to position the two hollow pile bodies during the docking and installation process.

[0009] The reinforcement mechanism is installed on the hollow pile body to strengthen the connection between the two hollow pile bodies.

[0010] In one possible design, the positioning mechanism includes four positioning blocks for positioning the two hollow pile bodies during installation. The bottom of the four positioning blocks is fixedly connected to the top four sides of the hollow pile body, and positioning holes are provided on the bottom four sides of the hollow pile body. The positioning blocks are inserted into the positioning holes.

[0011] In one possible design, the reinforcing mechanism includes a fixed ring and four reinforcing plates. The fixed ring is conical and is fixedly sleeved on the outer top of the hollow pile body. Notches are provided on all four sides of the fixed ring. A second rotating rod is welded to the bottom of each of the four reinforcing plates. The two ends of the second rotating rod are rotatably connected to the inner walls of the two sides of the notch, respectively.

[0012] In one possible design, the reinforcing plate has a through hole, through which a bolt for fixing the reinforcing plate to another hollow pile body is inserted. The bottom of the four sides of the hollow pile body has threaded holes, and the bolts are threadedly connected to the threaded holes.

[0013] In one possible design, the top four sides of the fixing ring are provided with grooves, and the grooves are provided with lifting rings to facilitate the hoisting of the hollow pile body. A first rotating rod is welded to one side of the lifting ring, and the two ends of the first rotating rod are rotatably connected to the inner walls of the two sides of the groove.

[0014] In one possible design, the inner wall of one side of the lifting ring is provided with an anti-slip groove to increase friction and prevent slippage.

[0015] In this application, during use, external hoisting equipment can lift the hollow pile body using a lifting ring, hoist it to the top of another hollow pile body, and align the positioning groove of the lifted hollow pile body with the four positioning blocks on the top of the other hollow pile body. After alignment, the lifted hollow pile body is lowered, allowing the positioning blocks to insert into the positioning grooves, thus positioning the two hollow pile bodies without the need for positioning tools, making it more convenient. Subsequently, personnel can weld and fix the two hollow pile bodies together. After completion, the bottom hollow column body reinforcing plate is rotated. The reinforcing plate is rotated via the second rotating rod, causing the top of the reinforcing plate to rotate onto the first hollow column body. At this time, the through hole of the reinforcing plate is aligned with the threaded hole, and then bolts are inserted. The bolts are rotated to connect with the threaded hole, connecting the two hollow pile bodies together, thus fixing and reinforcing them together. Of course, the two hollow pile bodies can also be fixed together without welding, improving installation efficiency. When not in use, the lifting ring can be rotated into the groove for storage.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this utility model, a hollow pile for civil engineering is provided. Through a positioning mechanism, the positioning groove of the suspended hollow pile body is aligned with the four positioning blocks on the top of another hollow pile body. After alignment, the suspended hollow pile body is lowered so that the positioning blocks are inserted into the positioning groove. This allows for the positioning of two hollow pile bodies without the need for positioning tools, making it more convenient.

[0018] In this utility model, a hollow pile for civil engineering is constructed by a strengthening mechanism. The bottom hollow column body strengthening plate is rotated, and the strengthening plate is rotated by a second rotating rod, so that the top of the strengthening plate rotates to the first hollow column body. At this time, the through hole of the strengthening plate is aligned with the threaded hole, and then a bolt is inserted. The bolt is rotated and threaded to connect with the threaded hole, thus connecting the two hollow pile bodies together. This allows for fixing and strengthening between the two hollow pile bodies.

[0019] In this utility model, the positioning mechanism can position the two hollow pile bodies, eliminating the need for positioning tools and making it more convenient. The reinforcing mechanism can fix and strengthen the two hollow pile bodies together. Attached Figure Description
