[0001] The utility model relates to the technical field of concrete pipe piles, in particular to a prestressed concrete pipe pile production auxiliary device. Background Art

[0002] Prestressed concrete pipe piles are a kind of tubular slender components driven into the soil, with a cross-sectional size much smaller than its length. The upper part of the pipe pile is connected to the cap (beam) to form a pile foundation. Its foundation structure is a prestressed concrete structure, which can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. It has the characteristics of large bearing capacity, good stability, small settlement value, etc., and can be mechanized for construction, which greatly improves the construction progress. Prestressed concrete pipe piles are suitable for low cap pile foundations of industrial and civil buildings, railways, highways and bridges, ports, docks, water conservancy and municipal structures and large equipment engineering foundations;

[0003] The existing prestressed concrete pipe pile mold is used to manufacture cylindrical solid concrete pipe piles. Due to the long length of the pipe pile, the connection auxiliary device needs to fix the pipe pile mold to seal the connection port of the pipe pile mold. The current connection auxiliary device has a poor fixing effect, which leads to the failure of manufacturing cylindrical solid concrete pipe piles.

[0004] Secondly, the concrete liquid is easy to overflow, which makes the appearance of the manufactured pipe piles not smooth enough, affecting the use of the pipe piles;

[0005] To this end, we propose a prestressed concrete pipe pile production auxiliary device to solve the problem that the connection auxiliary device of the above device has poor fixing effect, concrete liquid is easy to overflow, the appearance of the manufactured pipe pile is not smooth, and the use of the pipe pile is affected. Utility Model Content

[0007] To achieve the above object, the utility model provides the following technical solution: a prestressed concrete pipe pile production auxiliary device, comprising a first pipe pile mold and a second pipe pile mold, wherein the first pipe pile mold and the second pipe pile mold are fixedly connected and arranged in correspondence with each other up and down;

[0008] A feed port is fixedly installed on the top of the first pipe pile mold, a pressing plate is fixedly installed on the bottom of the first pipe pile mold, a sleeve is fixedly installed on the top of the second pipe pile mold, a connecting column is fixedly installed on the bottom of the pressing plate, and a surrounding block is fixed inside the sleeve.

[0009] Preferably, the feed port is interconnected with the first pipe pile mold, and the first pipe pile mold is interconnected with the second pipe pile mold.

[0010] Preferably, four positioning bolts are arranged around the top of the pressure plate, and six threaded holes are opened around the outer surface of the connecting column.

[0011] Preferably, four positioning threaded holes are arranged around the top of the sleeve, and six fixing bolts are arranged around the outer surface of the sleeve.

[0012] Preferably, the four positioning bolts are threadedly connected to the positioning threaded holes, and the six fixing bolts are threadedly connected to the threaded holes.

[0013] Preferably, the pressing plate is consistent in size with the sleeve, and the connecting column is consistent in size with the surrounding block.

[0014] Preferably, the connecting column is embedded in the sleeve and is fitted with the surrounding block, the contact surfaces of the connecting column and the surrounding block are fixedly provided with a demoulding layer, and the inner surfaces of the first pipe pile mold and the second pipe pile mold are both provided with a demoulding layer.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. This prestressed concrete pipe pile production auxiliary device, by arranging a connecting column to be embedded in the casing, is convenient for firm connection and fixation. When the connecting column is embedded in the casing, the lower end of the connecting column fits with the surrounding block, thereby increasing the tightness and stability of the first pipe pile mold and the second pipe pile mold. The nesting cooperation of the connecting column and the casing can avoid the phenomenon of offset, and the concrete liquid will not easily overflow when the concrete pipe pile mold is used to manufacture the pipe pile.

[0017] 2. Secondly, this prestressed concrete pipe pile production auxiliary device can achieve the function of positioning and fixing the connecting column and the sleeve by setting four positioning bolts and four positioning threaded holes for threaded connection and fixing, thereby ensuring the stability of the fixed connection between the first pipe pile mold and the second pipe pile mold. The six fixing bolts can be embedded into the threaded holes, and the fixing bolts and the threaded holes cooperate to perform surrounding threaded fixing on the connection between the first pipe pile mold and the second pipe pile mold, thereby achieving the purpose of fully fixing the first pipe pile mold and the second pipe pile mold, achieving effective and firm connection, and reducing the failure rate of concrete pipe pile production.
