Embodiment Construction

[0025] Such as figure 1 As shown, a transport mechanism for excavation and construction of a small-section tunnel includes a first straight track 1, a second straight track 2, a first arc track 3, a second arc track 4, and the first straight track 1 , the second straight track 2, the first arc track 3, and the second arc track 4 are respectively made up of two mutually parallel steel rails, the first straight track 1, the second straight track 2, the first arc track The rail 3 and the second arc-shaped track 4 are welded with a receiving iron plate 10 at the opposite rail waists of the two rails. The opposite receiving iron plates 10 on the inner sides of the two rails are connected by a connecting plate 5. The end of the straight track 2 close to the tunnel face 7 is connected to the first arc track 3, the end of the first straight track 1 and the second straight track 2 close to the tunnel opening 9 is connected to the second arc track 4, and placed on the track There are 1...

Abstract

The invention relates to the field of tunnel construction, in particular to a carrying mechanism for small-section tunnel excavation construction and a construction method. The carrying mechanism for small-section tunnel excavation construction comprises a first straight track, a second straight track, a first arc-shaped track and a second arc-shaped track. Steel bearing plates are welded at the opposite waists of two steel rails of each of the first straight track, the second straight track, the first arc-shaped track and the second arc-shaped track respectively. The opposite steel bearing plates inside the two corresponding steel rails are connected through connection plates. The first arc-shaped track is connected with one end, clear to a tunnel face, of each of the first straight track and the second straight track. The second arc-shaped track is connected with one end, clear to a tunnel portal, of each of the first straight track and the second straight track. An electric track car is placed on the tracks. The carrying mechanism and the construction method have the advantages that construction materials and tools both required by each construction procedure of small-section tunnels can be carried while the structural stability of the tunnels is guaranteed, and construction efficiency of the small-section tunnels is improved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a transport mechanism and a construction method for excavation construction of small-section tunnels. Background technique [0002] Nowadays, highways and railways are developing rapidly. Tunnel engineering is an important part of highway and railway construction. Tunnel excavation is carried out by multiple processes, mainly including tunnel face blasting, earth and stone transportation, steel arch Erecting, hanging nets, shotcrete anchors, initial support, secondary lining, and other processes, in the above-mentioned construction processes, it is necessary to transport a large number of tools, materials, etc. to the direction of the tunnel face. Transportation is usually carried out by means of transportation machinery, but for relatively small-section tunnels, it is difficult for transportation machinery to transport construction materials and tools in a limited tunnel space...
