Description

Technical Field

[0001] This utility model relates to the field of grouting engineering equipment technology, and in particular to an integrated grout mixing system. Background Technology

[0002] The grouting construction process control in water conservancy and hydropower is a complex control system. Through grouting, the grout penetrates, diffuses, and fills the grouting medium. After a certain period of time, the grout solidifies and hardens, thereby reinforcing the medium and achieving the purpose of seepage prevention and waterproofing. To ensure the successful implementation of the grouting process, a series of construction controls must be implemented. Specific parameters, control methods, and techniques must be selected during the construction process to make this hidden project controllable and achieve the intended grouting objectives.

[0003] In grouting operations, measuring the density, temperature, and volume of the grout is a crucial step. Currently, on-site construction typically uses separate equipment for measurement, consisting of a grout storage tank, a grout mixing tank, and a control cabinet. Density measurement is done by weighing. However, existing methods have the following problems in practical application:

[0004] 1. The placement of separate equipment is limited, and there are too many air pipes and cables, which takes time to arrange. In addition, the working efficiency of separate equipment is low: the working efficiency of pulp preparation, pulp change and pulp replenishment is slow.

[0005] 2. Weighing measurement methods have drawbacks such as poor accuracy and inaccurate measurements, resulting in suboptimal construction quality. Utility Model Content
