Intelligent large grouting equipment

Abstract

The invention discloses intelligent large grouting equipment, comprising an automatic feeding system, a grout liquidity auto-detection system, a weighing system, a control center system, a high-speed stirring system, a low-speed stirring system, an automatic grouting system, a cleaning system, an automatic water-adding system and a grout circulating loop system; a grouting agent charging tank is connected to the lower portion of a grouting agent feeding pipe, and cleaning outlet II is positioned below the grouting agent feeding pipe; a high-speed stirring barrel is fixed to a triangular frame through a weighing sensor and is measured and controlled via a microcomputer; the large grouting equipment also comprises a backup power system and a cleaning system. The intelligent large grouting equipment has the function of automatically metering raw material in static discharging state, accurate control for grout matching ratio is ensured, and effective guarantee is provided for grout compressive strength, flexural strength and performance indexes; the system can automatically detect the liquidity of grout, an operator needs to carry out irregular detection in non-fixed batches, and unqualified grout is avoided being pressed into a beam duct.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an intelligent large grouting equipment. Background technique [0002] Bridge construction is one of the important infrastructures of the country, and bridge engineering is a lifeline project related to the coordinated development of society and economy. The durability of bridges is the key factor for bridge safety and structural life. Due to the lack of important construction equipment, many construction units in our country failed to monitor and guide in real time during the operation process, resulting in human factors affecting the quality of bridges. A large number of bridges failed to achieve the designed durability, and there were diseases and deteriorations in normal use. These are because the construction quality does not meet the specifications and design requirements. Typical problems include insufficient material strength and unqualified construction...

AI Technical Summary

Problems solved by technology

The post-tensioned prestressed pipeline grouting construction of bridges is a key process that determines the overall durability of bridges. In my country, the traditional grouting method is mainly completed by manual control. The proportion of construction materials and construction techniques are relatively extensive and irregular, such as water glue Inaccurate ratio control, low credibility of grouting records, inability to exhaust the air in the tunnel during grouting, uncontrollable pressure, etc., resulting in incomplete grouting of pipelines, early corrosion of steel strands, low safety and poor durability of bridges
