Temperature measuring device and maintenance device for concrete track slab and coupon

Abstract

The invention provides a temperature measuring device and a maintenance device for concrete track slabs and coupons. The temperature measuring device comprises a first temperature measuring unit arranged on the core part of a concrete track slab and a second temperature measuring unit arranged on the core part of a concrete coupon, wherein both the first and second temperature measuring units comprise a probe and a detachable sleeve for encapsulating the probe. The temperature measuring device and the maintenance device provided by the invention can measure the temperature change of the concrete core part and record the curve of the concrete core part temperature changed with time. The temperature measuring system is completely controlled by a computer; and the data is accurate and the operation is simple, so the system can obtain accurate and valid data for a concrete laboratory.

Description

technical field [0001] The invention belongs to the field of concrete, and in particular relates to a temperature measuring device and maintenance equipment for concrete track slabs and test blocks. Background technique [0002] In the production process of concrete track slabs, steam curing is a very important process, which directly affects the strength of concrete products, the degree of stress release and other important indicators. At present, the maintenance of concrete is mostly realized by large curing pools and manual operations. The concrete bridge or track products and test blocks (test blocks refer to test blocks whose volume is much smaller than that of concrete bridge or track products) after forming are put into curing at the same time. In the pool, the curing temperature is measured by extending the temperature measuring probe into the curing cover, and the operator uniformly supplies and holds air according to the measured curing temperature. However, this ...

AI Technical Summary

Problems solved by technology

However, this method cannot measure the real temperature change inside the concrete during the curing process, so it cannot accurately evaluate the performance of the formed concrete track slab, and the curing process is completed manually, and the error of temperature control is large, so it is difficult to guarantee High quality of concrete track slabs
