Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, and more specifically, to a PCCP grouting device. Background Art

[0002] Prestressed concrete cylinder pipe, abbreviated as PCCP, refers to a water pipe made by winding circumferential prestressed steel wire on a high-strength concrete pipe core with a steel cylinder, and then spraying a dense cement mortar protective layer on it. It is a composite pipe composed of thin steel plate, high-strength steel wire and concrete. It fully and comprehensively utilizes the tensile strength and easy sealing of steel and the compressive strength and corrosion resistance of concrete, and has the characteristics of high sealing, high strength and high impermeability. In the production process of PCCP, the concrete used needs to be grouted. The grouting and molding of PCCP pipe cores are all manually fed. The mixed concrete material is added to the core mold molding mold with a shovel, and the grouting device is used, which is more efficient and reduces labor costs.

[0003] However, there are various types of grouting devices in the prior art. For example, utility model patent CN221665527U relates to a winter PCCP sealing grouting device, which includes a bottom waterproof layer, and the surface of the bottom waterproof layer is adhered with an electric heating felt. By arranging a bottom waterproof layer and an insulation layer, the utility model can preheat the pipe body before grouting during winter construction of the PCCP pipeline. After the preheating is completed, mortar is poured into the grouting seam. After the grouting is completed, the mortar at the grouting seam is continued to be heated and insulated. After the mortar strength reaches the requirement, the heating and insulation device is removed. Preheating and heating and insulation can shorten the mortar curing time, speed up the construction progress, and at the same time, avoid the occurrence of problems such as ice and freezing.

[0004] Although the grouting device can preheat the mortar to achieve the purpose of heating and heat preservation, it is quite difficult to ensure the density of the grouting during use. Bubbles and gaps are prone to appear, and it is difficult to improve the density of the grouting mortar while grouting. The mortar has poor uniformity and quality, which is not conducive to improving the strength and durability of the concrete mortar. In order to avoid this phenomenon, it is very necessary to design a PCCP grouting device. Utility Model Content
