Abstract

The invention discloses concrete for rail weigher. The concrete is prepared from the following raw materials in parts by weight: 85 to 95 kg of cement, 120 to 140 kg of sand, 200 to 230 kg of stone, 110 to 150 kg of water, and 22 to 30 kg of additives. The preparation method of the concrete for the rail weigher construction comprises the following steps: according to the proportion of various components, successively adding the stone, sand, cement and additive into a stirring drum of a stirrer, while in stirring, and adding the water into the stirring drum in multiple steps. The construction method adopting the concrete for the rail weigher comprises four steps of crushing a waste bedbase, binding a reinforcing bar cage, pouring and erecting a mold, and removing the mold. According to thetechnical scheme of the invention, tThe prepared concreteis characterized by havings excellent physical and chemical performance and short construction period, and durable, and high in safety performance; and the construction period is only one fifth of the traditional construction period, so that the time from the construction to the application of the rail can be greatly shortened, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to concrete and a construction method thereof, in particular to a concrete for track scale construction, a construction method and application thereof. Background technique [0002] Rail scales are weighing instruments for weighing railway trucks. They are roughly divided into three types: static rail scales, dynamic rail scales and light rail scales. They are widely used in factories, mines, metallurgy, foreign trade and railway departments to weigh bulk goods on trucks. Especially in the coal mining industry, it is widely used. [0003] The track scale mainly consists of concrete base, column, installation preset platform, mechanical platform, sensor system, etc. [0004] Since rail scales are used to weigh bulk goods such as coal, the performance requirements for the bearing cement parts are relatively high. [0005] However, the cement parts used on the track scale in the prior art, such as the bearing base, are all obtained...
