Temperature-controlled crack prevention construction method for concrete structure

Abstract

The invention discloses a temperature-controlled crack prevention construction method for a concrete structure. The method comprises the steps of (1) arranging temperature probes on the surface of a large-size concrete pouring block to measure the temperature difference between inside and outside, the cooling rate of the large-size concrete pouring block and the environment temperature; (2) establishing a calculation model for the temperature-controlled construction scheme based on the obtained measuring result; (3) collecting the construction site parameters, and inputting the parameters into the obtained calculation model for temperature-controlled simulation calculation; and (4) comparing the temperature-controlled simulation calculation result obtained in the step (3) with the preset auxiliary expert system, repeating the step (2) to adjust the corresponding parameters when the temperature-controlled simulation calculation result obtained in the step (3) and the preset auxiliary expert system mismatch, and optimizing the temperature-controlled crack prevention construction scheme for concrete preset based on experience until the optimal temperature-controlled crack prevention construction scheme for the concrete is obtained. The temperature-controlled crack prevention construction method for the concrete structure disclosed by the invention has the advantages that the concrete is not prone to crack, the crack prevention reliability is high, and the crack prevention commonality is good.

Description

technical field

[0001] The invention relates to the technical field of concrete crack prevention, in particular to a temperature-controlled crack prevention construction method for concrete structures. Background technique

[0002] At present, our country is in a climax stage of infrastructure construction. A number of major engineering projects are being planned and constructed in various regions. Many hot issues have emerged and may arise. They are directly related to the benefits of the project and affect the national economy and development. long-term development of society. Among these hot issues, the cracking of concrete structures is not only an old problem, but also a new technology subject that has drawn much attention from all parties. Since the emergence of concrete materials, cracks have generally existed in various concrete structures, such as dams, bridges, tunnel linings, sluices, pumping stations, culverts, port works, foundations, etc.
