Embodiment 1

[0023] Example 1, such as Figure 1-2 Shown:

[0024] A tunnel brick for engineering construction, the upper part of the brick body 1 of the tunnel brick is provided with several partitions 4, and the partitions 4 separate the tunnel brick into several grooves 6 with the same size; the front of the groove 6 The wall and the rear wall are symmetrically provided with screw holes 5 for threaded connection between the upper and lower tunnel brick structures; the left side of the brick body 1 is provided with a side convex 2 structure, and the right side of the brick body 1 is provided with a The undercut 3 structure matched with the side convex 2 is used for the lateral fitting connection between the left and right adjacent spliced ​​tunnel bricks; the material of the brick body 1 is a mixture of fly ash and concrete.

[0025] In one aspect of the present invention, through the improved design of the tunnel brick structure, the tunnel brick can be used as a reinforcing rib struct...

Abstract

The invention relates to the field of tunnel brick structures for engineering construction, in particular to tunnel bricks for engineering construction. A plurality of partition plates are arranged atthe upper part of a brick body of each tunnel brick and partition the tunnel bricks into a plurality of groove structures with same sizes; threaded holes are symmetrically formed in the front walls and the rear walls of grooves correspondingly and used for threaded connection between upper tunnel brick structures and lower tunnel brick structures; side convex structures are arranged on the left side faces of the brick bodies correspondingly, side concave structures matched with the side convex structures are arranged on the right side faces of the brick bodies correspondingly, and the side convex structures and the side concave structures are used for side matching connection between the left-right adjacent splicing tunnel bricks; and each brick body is made of a mixture of fly ash and concrete. According to the tunnel bricks for engineering construction, the structure is simple, materials are saved, piling is convenient, and good practical value is achieved.

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...
