A concrete slump detection device for road pouring

Abstract

The invention discloses a concrete slump detection device for road pouring, which relates to the technical field of road engineering. The invention comprises a base; a surface of the base is respectively fixedly connected with a dial and a plurality of fixed seats; a surface of several fixed seats is fixedly connected with a support tube; the bottom of the inner surface of the support tube is fixedly connected with a hydraulic rod; one end of the hydraulic rod runs through the support tube and Extending to the outside of the support tube; one surface of several support tubes is fixedly connected with a U-shaped plate; the opposite inner surfaces of the U-shaped plate are provided with limiting grooves; the sides of the limiting grooves are slidably connected with connecting plates. The present invention, through the design of the stripping board, the slot, the coaming, the coaming and the dial, on the one hand adds a protective structure to the dial, avoids the surface of the dial from being stained by concrete, reduces the recognition of the dial, and thus improves the reliability of the device. The service life, on the other hand, facilitates centralized cleaning of concrete waste after the test is completed after the test, reducing the difficulty of cleaning the concrete.

Description

technical field [0001] The invention belongs to the technical field of road engineering, in particular to a concrete slump detection device for road pouring. Background technique [0002] Slump mainly refers to the plasticizing performance and pumpability of concrete, that is, the workability of concrete. Specifically, it is to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. The slump is a quantitative index to measure its level, which is used to judge whether the construction can be carried out normally; the workability refers to whether the concrete is easy to construct and operate and the performance of uniform compactness, which is a very comprehensive performance, including flow properties, cohesion and water retention; concrete slump is mainly affected by gradation changes, water consumption per unit volume, water-cement ratio, sand ratio, and including cement types, aggregate conditions, time and temperatur...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a concrete slump detection device for road pouring, which solves the problem of existing concrete slump through the design of waste stripping plate, marking plate, limit rod, positioning pile, horizontal scale and vertical scale. After the test of the slump detection device, it is inconvenient to clean up the waste in a centralized manner, and it is impossible to measure the slump and expansion of the concrete at the same time. At the same time, the improvement of the electric lifting mechanism further ensures the verticality of the slump cylinder during the lifting process.
