AI Technical Summary

Technical Problem

Traditional methods for preparing precast concrete cable troughs for railways suffer from problems such as low precision in mold making, unreasonable selection and proportioning of raw materials, uneven mixing, non-standard pouring and vibration processes, inaccurate placement of reinforcing steel cages, and improper control of the curing process. These problems result in large dimensional deviations, insufficient strength, poor durability, and loose structure of the cable troughs, which fail to meet the high standards required for railway construction.

Method used

By employing precise mold making, strict selection and proportioning of raw materials, standardized concrete mixing, pouring and vibration processes, precise placement of steel reinforcement cages and scientific curing, combined with rigorous inspection procedures, we ensure that the cable troughs are dimensionally accurate, structurally compact, high in strength and durable, meeting the needs of railway construction.

Benefits of technology

It improves the quality and performance of cable troughs, meets the stringent requirements of railway construction, ensures the safe and reliable operation of railway projects, reduces production costs, minimizes rework delays and resource waste, and extends service life.

Abstract

The invention discloses a railway concrete prefabricated cable trough preparation method, and belongs to the technical field of cable trough preparation, and the railway concrete prefabricated cable trough preparation method comprises the following steps: preparing a mold: preparing a mold with an accurate size and a smooth surface according to design requirements, providing a basis for subsequent concrete pouring, selecting and proportioning raw materials, and preparing a prefabricated cable trough; the method comprises the following steps: strictly selecting materials, mixing cement, aggregate, reinforcing steel bars and other raw materials according to a ratio, providing a high-quality base material for concrete preparation, stirring concrete, adding a proper amount of water into the raw materials, stirring to form uniform concrete, enabling the concrete to have good workability and uniformity, preparing for pouring, and pouring and vibrating the concrete. Concrete is poured into the mold and vibrated and compacted to remove bubbles, it is ensured that all corners of the mold are filled with the concrete, conditions are created for subsequent placement and maintenance of the steel reinforcement framework, the steel reinforcement framework is placed, the steel reinforcement framework is accurately placed in the vibrated concrete, and the structural strength of the cable trough is enhanced.
