Abstract

The present invention relates to the field of tunnel brick structures for engineering construction, in particular to a tunnel brick for engineering construction. The upper part of the brick body of the tunnel brick is provided with a number of partitions, and the partition boards separate the tunnel brick into several grooves of the same size. structure; the front wall and the rear wall of the groove are symmetrically provided with screw holes for the screw connection between the upper and lower tunnel brick structures; the left side of the brick body is provided with a side convex structure, and the right side of the brick body There is an undercut structure matching the side convex on the top, which is used for the lateral fit and connection between the left and right adjacent spliced ​​tunnel bricks; the material of the brick body is a mixture of fly ash and concrete. The invention has the advantages of simple structure, material saving, convenient stacking and good practical value.

Description

technical field [0001] The invention relates to the field of tunnel brick structures for engineering construction, in particular to a tunnel brick for engineering construction. Background technique [0002] At present, in the field of tunnel engineering and construction, the specific use of tunnel bricks is indispensable. During the use of tunnel bricks in construction, on the one hand, it is necessary to ensure the structural strength of the tunnel bricks to ensure that the tunnel bricks can play a good supporting role; on the other hand, it is necessary to facilitate the splicing and installation of the tunnel bricks. [0003] However, the existing tunnel bricks still have some deficiencies in the specific use process. Specifically, on the one hand, although the strength of the existing tunnel bricks can be effectively guaranteed during use, the overall structure of the tunnel bricks consumes relatively large materials. The cost of raw materials is increased; on the oth...
