Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a prefabricated pipe pile core concrete pouring device. Background Art

[0002] Precast pipe pile core concrete is a concrete material used to fill the pile core in precast pipe piles. Precast pipe piles are a kind of foundation structure commonly used in construction projects. They are composed of reinforced concrete pipes and concrete pile cores, and precast pipe pile core concrete is a concrete material filled in the concrete core column of concrete pipe piles.

[0003] The preparation process of precast pipe pile core concrete is usually carried out in a concrete mixing station, which mixes water, cement, sand, stone and other raw materials in a certain proportion, and then transports the concrete pump truck to the construction site of the precast pipe pile. At the construction site, the concrete pump truck transports the concrete into the core column of the precast pipe pile, and then vibrates it to ensure the density and uniformity of the concrete.

[0004] The main function of the core concrete of precast pipe piles is to enhance the bearing capacity and stability of precast pipe piles. In the construction process of precast pipe piles, the filling and vibration of the core concrete is a very critical link, which directly affects the strength and stability of the precast pipe piles. Therefore, in the construction process, it is necessary to strictly control the proportion of concrete and the construction quality to ensure the safety and reliability of precast pipe piles.

[0005] The existing prefabricated pipe pile core concrete pouring device is generally designed to prevent a large amount of concrete from being retained in the conveying pipe, which is prone to shifting and spilling. This not only causes material loss and increases the cost of concrete pouring, but also pollutes the construction site environment, resulting in the need for secondary cleaning of concrete residues and waste of manpower and material resources. Improvements are being made, for example, the simple device for pouring prefabricated pile core concrete disclosed in the authorized Chinese patent CN210712850U can be used in conjunction with structures such as the device body, the first valve plate, the sealing part, the drawing part, the pipe joint, the inner groove, the second valve plate, the stop part, the rotating part, the rotating shaft, the gripping part and the locking part to enable workers to directly manually control the opening or closing of the conveying channel of the simple device, so as to avoid concrete spilling everywhere before moving to the next pouring point, maintain the on-site construction environment, save the cost of secondary cleaning of concrete residues, greatly reduce the waste caused during concrete pouring, and reduce costs.

[0006] However, when the prefabricated pipe pile core concrete pouring device in the above-cited document is in use, concrete often adheres to the end face of the discharge port of the device body. If it is not cleaned in time, the end face of the discharge port will become uneven after the concrete solidifies, causing interference with the discharge pipe during the next pouring, thereby affecting the pouring efficiency, resulting in the need to improve the use effect of the existing concrete pouring device.
