Mortise and tenon type prefabricated interlock block arch revetment

Abstract

The invention provides a mortise and tenon type prefabricated interlock block arch revetment. The revetment comprises a first prefabricated block of an arch column straight line section, a second prefabricated block, a third prefabricated block and a fourth prefabricated block of an arch column transition section and a fifth prefabricated block of an arch ring section, wherein the prefabricated blocks are sequentially connected in a mortise and tenon mode to form standard connection sections, and the standard connection sections extend longitudinally and vertically in a roadbed slope in a repeated combination manner. According to the revetment, arch frameworks are composed of high-strength prefabricated blocks with weight reduction effects, after the prefabricated blocks are connected by adopting mortise and tenon type joints, an integral interlock block is formed, and the integral interlock block is arranged on the roadbed slope to form an industrialized roadbed slope arch protectionstructure.

Description

technical field [0001] The invention relates to the field of roadbed slope protection, in particular to an arched slope protection of mortise and tenon type prefabricated high-strength interlocking blocks. Background technique [0002] Arched skeleton slope protection is a common engineering protection scheme in roadbed slope protection. It is commonly used for slopes with embankment filling heights greater than 4 meters in existing expressways and local road network projects. Skeleton materials are often made of masonry rubble, and cast-in-place concrete and precast concrete are also used in areas where stone materials are scarce. [0003] With the increase of labor costs, the economic advantages of masonry masonry and cast-in-situ concrete arch protection are no longer prominent. At the same time, the engineering quality of the construction site is not easy to control. Collapse and other diseases. Therefore, the construction party is more inclined to precast concrete arc...

AI Technical Summary

Problems solved by technology

[0005] 1. There is a lack of connection measures between the prefabricated blocks, which may easily cause overall instability and collapse

[0006] 2. Low-strength concrete is generally used in prefabricated blocks, and the thickness can only be increased to ensure its own strength, which will cause a vicious circle of large thickness, heavy weight, and inconvenient installation
