Automatic grouting system

Abstract

The invention discloses an automatic grouting system, and belongs to the technical field of bridge prestress grouting. The system comprises a slurrying system, a slurry storage system, a grouting system and a vacuum system, and further comprises a control module, a high-speed stirring barrel weighing sensor, a high-speed stirring motor current transformer, a discharging motor current transformer, a low-speed stirring barrel weighing sensor, a low-speed stirring motor current transformer, a pressure transmitter, a slurry pouring valve position sensor, a vacuum degree sensor, a voice module and corresponding alternating current contactors used for controlling motors to be started and stopped. The sensors and the pressure transmitter are used for providing input signals for the control module, and the voice module and the alternating current contactors are connected with the control module and controlled by the control module. The system realizes automatic cooperative control of two key processes of feeding pulping and vacuum grouting in grouting construction, and has the characteristics of high automation degree, accurate metering of the burdening and grouting amount, convenience and quickness in field movement, convenient operation, high working efficiency, reliability, durability, small maintenance amount and the like.

Description

technical field [0001] The invention relates to the technical field of bridge prestressed grouting, in particular to an automatic grouting system. Background technique [0002] The prestressed concrete structure in our country was developed in the 1950s. It was initially used for prestressed reinforced concrete sleepers, and then prestressed concrete was promoted nationwide. With the construction of high-grade highways and high-speed railways in my country, prestressed concrete technology has been widely used in highway, railway and bridge engineering. [0003] Traditional prestressed grouting has many defects such as inaccurate ingredients, insufficient mixing, and uncontrollable pressure holding time, which cannot guarantee the safety and reliability of prestressed grouting, which has become the main factor restricting the application and development of prestressed structures. [0004] The grouting quality of the prestressed channel determines the safety and durability of...

Problems solved by technology

However, the traditional grouting process cannot fully guarantee the compactness of grouting, the degree of automation is low, the measurement of ingredients and grouting volume is inaccurate, and it cannot meet the technical requirements of pipeline grouting construction for process control and product quality
