Description

TECHNICAL FIELD

[0001] The utility model relates to pre -stressed steel cylinder concrete pipe (PCCP) construction equipment technology technical field, more specifically, the utility model relates to a kind of pre -stressed steel cylinder concrete pipe uniform feeder. BACKGROUND

[0002] Prestressed concrete cylinder pipe (PCCP) is widely used in urban water supply, drainage, industrial water supply and other fields, due to its good strength, impermeability and durability, it can withstand high internal pressure and external load, so it plays an important role in large-scale water conservancy projects and municipal infrastructure construction.

[0003] The existing equipment is shaped by bottom support, inner mold and outer mold vertical vibration forming process, for example, it takes 6 workers one hour to complete the manual feeding of a pipe core with an inner diameter of 2000mm, and it takes longer time to feed larger diameter pipes, especially in summer when the temperature is high and the concrete setting time is fast, if the initial strength is reached, the operation time is prolonged, which will inevitably affect the quality of the pipe core concrete

[0004] According to the search, the Chinese patent with the authorization announcement No.CN114274337A discloses a pre-stressed steel cylinder concrete pipe automatic vibration-free self-compacting uniform feeder, the outer cone cover body assembly and the inner cone cover body assembly are sleeved together and connected by a middle shaft. After sleeving, there is a conical cavity between the two, one of the two is driven to rotate by a driving motor, the rotating body is uniformly distributed with spiral push plates on the inner wall of one side of the conical cavity, the adjacent spiral push plates have a width smaller than the width of the cone top, and each spiral push plate has a height greater than the height of the cone top. The application of the present application makes the concrete feeding and distribution more uniform, and some embodiments adopt automatic compaction function, so that it can be applied to ordinary concrete and self-compacting concrete.

[0005] However, in actual use, the amount of concrete is crucial to the quality of the pipe, if the amount of concrete is too much, the pipe wall may be too thick, which not only increases the cost, but also may affect the size accuracy and performance of the pipe, on the contrary, too little amount will lead to thin pipe wall, reducing the strength and durability of the pipe.

Adjust according to the thickness of the prestressed steel barrel concrete pipe to be made so that the equipment can always be clamped on the mold. Attached Figure Description
