Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, and particularly relates to a pipe pillow end plugging and pouring device for pipeline construction. Background Technique

[0002] During pipeline construction, pillow beams, pillow bases, and pipeline side pillows are generally set for support and fixation; pillow bases and side pillows generally have two construction schemes: prefabrication and on-site pouring; most prefabricated parts are only applicable to and targeted at single pipe fittings, while in-situ pouring has stronger adaptability; during the in-situ pouring process, when pouring the concrete of the pipe pillow of the rainwater pipeline, template support or bag plugging is mostly used, and how to handle the pouring of the end part to achieve both the quality requirements and beautiful effect has always been a construction difficulty. The traditional method of supporting the template at the end has low construction efficiency, high resource consumption, does not meet the construction requirements of energy conservation and environmental protection, and the end template has poor portability and is not easy to be firm, often resulting in concrete leakage, which affects the progress and quality of the project;

[0003] After retrieval, a precast pillow beam for a municipal engineering concrete pipeline with the prior art publication number CN217683557U includes a pair of symmetrically arranged pillow beam bodies; the pillow beam body is basically a rectangular block, and the top surface of the pillow beam body consists of an external top surface and an internal top surface. The external top surface is a horizontal plane parallel to the bottom surface of the pillow beam body, and the internal top surface is a concave arc surface; a template slot is opened on the external top surface of the pillow beam body, and a lifting hole is opened on the surface of the pillow beam body and inside the template slot; this scheme uses the method of prefabricating the pillow beam for advance production; advance prefabrication has certain advantages and can be carefully made step by step, but at the same time, there are also corresponding disadvantages, that is, the pillow beam body and the end part cannot adapt to the actual construction environment and are rather inflexible during construction;

[0004] A mold for manufacturing a pipe pillow for a circular pipeline in a road drainage project with the prior art publication number CN213081839U includes an inner side plate, an outer side plate, a front side plate, a rear side plate, and a reinforcing rib plate; the inner side plate, the outer side plate, the front side plate, and the rear side plate enclose a fixed frame, and the reinforcing rib plates are arranged in parallel inside the fixed frame; the height of the inner side plate is lower than that of the outer side plate; the reinforcing rib plates are lower on the inside and higher on the outside and are parallel to the front and rear side plates; the inner side plates of the two groups of templates are arranged oppositely;

[0005] The disadvantages of this scheme are that the size, shape, and model of the pipe pillow and the pipe pillow end made by this mold are of a fixed type. Especially, the inclined surface of the reinforcing rib plate is a straight section. Although it has strong adaptability to support the pipeline, it cannot fix the pipeline firmly when supporting the pipeline, providing conditions for the pipeline to shake. Summary of the Invention
