A method for manufacturing an arched frame for highway and railway tunnels

Abstract

The invention discloses an arch fixing rack for a highway / railway tunnel and a manufacturing method of the arch fixing rack. A main body comprises rib columns and arch rings; the arch rings are arranged on two sides of the rib columns; the part between the rib columns and the arch rings is filled with rammed earth; shrubs are planted on the rammed earth; the bottom of the main body is of a Z-shaped hollow structure; a drainage groove is formed inside the main body; macadam cushion layers are respectively arranged at the bottoms of the rib columns and the arch rings; the connection parts of the rib columns and the arch rings are of staggered tooth structures; curbing is mounted on two sides of the rib columns and inner sides of the arch rings; the rib columns are of hollow structures; through holes are formed around the centers of the arch rings; reinforcing steel bars are connected in series inside the through holes. The invention further discloses a manufacturing method of the arch fixing rack. The arch fixing rack for the highway / railway tunnel is convenient and rapid to construct, good in pressure resistance, good in water drainage property and long in service life.

Description

technical field [0001] The invention relates to an arched frame and a manufacturing method thereof, in particular to an arched frame used in highway and railway tunnels and a manufacturing method thereof, and belongs to the technical field of infrastructure processing. Background technique [0002] The arched frame is widely used in the slope protection projects of railways, highway subgrades and water conservancy dams because of its beautiful shape, good slope drainage protection effect, low cost, green vegetation in the arch, and coordination with the surrounding environment; At present, most of the arched frames are built by on-site mortar rubble masonry. Affected by the level of masonry technology, the size is often inaccurate and the shape is wrong, resulting in incorrect structural force and the collapse of the arch ring; The grade of the flakes is not high and the structure is loose. Once the bottom of the arch ring is hollowed out, it will collapse and fail as a whol...

[0002] The arched frame is widely used in the slope protection projects of railways, highway subgrades and water conservancy dams because of its beautiful shape, good slope drainage protection effect, low cost, green vegetation in the arch, and coordination with the surrounding environment; At present, most of the arched frames are built by on-site mortar rubble masonry. Affected by the level of masonry technology, the size is often inaccurate and the shape is wrong, resulting in incorrect structural force and the collapse of the arch ring; The grade of the flakes is not high and the structure is loose. Once the bottom of the arch ring is hollowed out, it will collapse and fail as a whole; at the same time, the on-site operations are often inefficient, slow in progress, poor in quality, occupy a large area, and consume less labor and time.
