Anchor rod supporting device for tunnel open cut backfilling

Abstract

The invention provides an anchor rod supporting device for tunnel open cut backfilling, and relates to the field of tunnel construction devices. The anchor rod supporting device for tunnel open cut backfilling is built on a cutting. The anchor rod supporting device comprises a support, wherein the support is composed of a plurality of transverse steel bars and a plurality of longitudinal steel bars, and two bases are arranged on the two sides of the support correspondingly. According to the anchor rod supporting device for tunnel open cut backfilling, a protective plate, the bases and verticalplates are matched with one another to form a protective wall, and a cutting slope is blocked. The influence of the landslide of the cutting slope on construction is prevented. The transverse steel bars, the longitudinal steel bars and supporting rods are matched with one another to replace manual bricklaying, the construction speed is increased, and the labor intensity of workers is reduced. Theaccuracy of the supporting size is improved. The influence of errors caused by manual bricklaying on the supporting bearing performance is avoided. The cutting slope is accelerated by means of the cooperation of positioning rods and steel wire meshes, then falling stones are received through elastic net bags, and the damage of falling stones at the high position of the cutting slope to the support is prevented.

Description

technical field [0001] The invention relates to the technical field of tunnel construction devices, in particular to a bolt support device for backfilling open holes in tunnels. Background technique [0002] In the construction of tunnels in mountainous areas, some sections are prone to landslides, falling rocks or flow rocks, and mud flow hazards. If it is built by underground excavation, the mountain will often collapse and it will be difficult to construct. To this end, it is necessary to adopt the open cut method, first digging a steep temporary slope into a cutting or a half cutting, building a lining structure in it, and then backfilling the outer surface of the lining with earth and rocks. [0003] Traditional construction methods, such as "a construction method for connecting long open tunnels between bridges and tunnels in high and steep terrain", have been disclosed in the China Patent Network, and the patent number is 201910378931.8. Above-mentioned method first...
