Prestress grouting device

Abstract

The invention discloses a prestress grouting device. The prestress grouting device comprises a stirring barrel used for producing and outputting sizing, a grouting pump used for pouring the sizing into prestress beam holes, a liquid level detector which is connected between the stirring barrel and the grouting pump and used for detecting the liquid level of the sizing outputted by the stirring barrel and generating a corresponding liquid level signal, and a controller which is connected with the liquid level detector and the grouting pump and used for controlling the running state of the grouting pump according to the liquid level signal. Compared with an existing prestress grouting device, the prestress grouting device is simple in structure and capable of rapidly and accurately detecting the liquid level in real time, and therefore the prestress grouting device can more accurately and reliably control the grouting pump, the dry grinding phenomenon can be effectively prevented from happening to the grouting pump, the service life of the prestress grouting device is prolonged, the after-sale maintenance cost of the prestress grouting device is greatly reduced, and construction cost is saved.

Description

technical field [0001] The invention relates to the technical field of prestressed grouting, in particular to a kind of prestressed grouting equipment. Background technique [0002] Prestressed pipe grouting technology is widely used in buildings, bridges and special engineering structures, and it is an indispensable and important part of construction technology. [0003] The role of prestressed pipe grouting is mainly composed of three points: one is to protect the prestressed steel bars from being exposed and corroded, and to ensure the safety of prestressed concrete structures or components; The effective transmission of prestress makes the prestressed steel and concrete work together; the third is to eliminate the fatigue damage of the anchorage caused by the stress change of the prestressed structure or components under repeated loads, so as to improve the reliability and durability of the structure. [0004] Prestressed grouting equipment is a device that uses prestre...

AI Technical Summary

Problems solved by technology

In practical applications, human factors still play a leading role, often due to the dry grinding of the grouting pump, the amount of grout at the grouting outlet is small, and the pressure cannot meet the grouting requirements, resulting in the termination of the construction

At the same time, dry grinding of the grout pump will also lead to the failure of the grout pump, resulting in higher after-sales maintenance costs for the entire equipment, which also delays the construction progress
