Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a grouting device for tunnel and bridge construction. Background Art

[0002] In the construction of tunnels and bridges, compared with house construction, there will be dense steel bars. Due to the complexity of embedded parts, it is not very convenient to use traditional cement pouring. Grouting concrete can solve this problem well. It is to fill the coarse aggregate of concrete into the template in advance, and then use a pump to press the cement mortar into it to solidify it into stone. This method of construction can be used to grout and fill leaks and reinforce the structure of various construction cracks, expansion joints, construction joints and structural joints, which can significantly improve the efficiency of construction. Most of the existing grouting devices do not stir the mortar when storing it, which easily leads to mortar coagulation. At the same time, there is no good filtration for large pieces of solid mortar, which causes the spraying pipe to be easily blocked, reducing work efficiency.

[0003] To this end, we invented a grouting device for tunnel and bridge construction. Utility Model Content
