Pipe shed construction method adopting three-arm drill jumbo

Abstract

The invention relates to a pipe shed construction method adopting a three-arm drill jumbo. The construction method includes the steps that first, an indicator lamp is connected with a power source, sothat cutters are separated; second, a drill rod is driven to rotate through the three-arm drill jumbo, the drill rod drives a drill bit to drive the cutters to rotate by taking the drill rod as the axis, a hole is formed in a mountain by the cutters, and parts, entering the drill bit and the drill rod, of the mountain body form mountain body residues; third, when the drill bit enters the mountainbody until an outward flanging squeezes a normally-open button switch to enable the indicator lamp to be turned on, a metal pipe is driven to be inserted into the hole, pressing on the normally-openbutton switch is released, and the second step and the third step are repeated to enable the hole to penetrate through the mountain body; and fourth, the mountain body residues are removed, the drillrod is retracted after the cutters are folded, the drill bit and the drill rod are withdrawn from the metal pipe, and the metal pipe is reserved in the hole to form the wall of the hole. According tothe pipe shed construction method adopting the three-arm drill jumbo, the three-arm drill jumbo is used for driving to form the hole, so that the hole is formed in the mountain body.

Description

Technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a construction method of a three-arm rock drilling rig pipe shed. Background technique [0002] In the construction of highways, railways, and water conservancy and hydropower projects, the proportion of tunnels will become larger and larger; in the tunnel excavation construction, the existing construction includes shallow hole drilling pipe shed construction and three-arm rock drilling rig construction. The construction of shallow-hole drill pipe sheds has problems such as large environmental pollution, poor hole quality, and easy hole collapse, which cannot meet the requirements of environmental protection, low energy consumption, economy, and high safety and quality. The construction process of the three-arm rock drilling rig has less environmental pollution, higher safety factor, low cost, and less energy consumption. It has significant advantages over traditional tunn...
