Method for real-timely monitoring construction interlayer bonding time of roller compacted concrete

Abstract

A method for real-timely monitoring construction interlayer bonding time of roller compacted concrete comprises the steps: GPS positioning devices and radio station differential devices are installed on a leveling machine and a rolling machine and used for acquiring real-time dynamic data of construction machinery; data transmission devices are installed on the leveling machine and the rolling machine and used for sending the received real-time dynamic data of the construction machinery to a heat-rising layer monitoring system server-side installed in an application server; the application server puts the received real-time dynamic data in order, transmits to a database server for storage, analyzes and processes the real-time dynamic data, transmits to a client-side for exhibition and then pre-warns or alarms; the client-side real-timely receives the data sent by the server-side and displays the conditions of the heat-rising layers of each storehouse surface in a graphic form; and the database server receives and stores the data. According to the method for real-timely monitoring construction interlayer bonding time of roller compacted concrete, roller compacted strip construction time, interlayer interval time and interlayer covering time during the construction of a dam roller-compacted construction layer can be real-timely monitored, fed back and controlled.

Description

technical field [0001] The invention relates to a method for monitoring the construction quality of a roller compacted concrete dam in a water conservancy project. In particular, it relates to a method for real-time monitoring of bonding time between layers of roller compacted concrete construction. Background technique [0002] Roller compacted concrete is a kind of dry hard cement-poor concrete, which is mixed with Portland cement, fly ash, water, admixtures, sand and grading-controlled coarse aggregate to make dry hard concrete without slump. Compared with normal concrete, roller compacted concrete is mixed with a large amount of fly ash, which reduces the amount of cement used, thereby reducing the heat of hydration, which is beneficial to the temperature control of the dam. During the construction process, the roller compacted concrete dam adopts the same transportation and paving equipment as the earth rock dam construction, and uses a vibratory roller compactor to co...

Problems solved by technology

[0005] In summary, although the current research on the bonding quality of RCC interlayers is extensive, most of them focus on the control of concrete raw materials and macroscopic qualitative control methods, and focus on the precise and real-time monitoring of the closing of RCC after entering the warehouse and the rolling process. It has not yet been involved. At present, the control of the interlayer bonding time of RCC mainly relies on the observation of the supervisors at the side station, and roughly obtains the thermal rise time, and artificially judges whether it exceeds the interlayer bonding time control standard. The data error or even omission of part of the surface of the warehouse brings great hidden dangers to the quality control of the interlayer bonding of RCC
