A construction method using an arch installation machine

Abstract

The invention relates to a method for construction by means of an arch center mounting machine. The arch center mounting machine comprises a storage rack, an underframe, a driving cab, a clamping arm,a hanging basket assembly, supporting legs, a connecting rack, a hollowed part, a swing arm, a hydraulic motor, a limiting bump, an upper clamping plate, a triangular block, a circular bead, an upperbase plate, a lower base plate, a lower clamping block, a clamping oil cylinder, a rotating mechanism, a cylindrical connecting part, a swing arm oil cylinder and an annular connecting part, whereinthe hanging basket assembly comprises a support, a pitch oil cylinder, an outer arm, a telescopic oil cylinder, a leveling oil cylinder, a hanging basket, a back table, a ladder, an inner arm, a firstjoint, a second joint, a caterpillar band and a rotary driving mechanism. The construction method comprises the following steps: a prepared construction method, a linked construction method and an adjustable construction method. The prepared construction method comprises the following steps: pre-preparing an arch center; processing a mounting position of the arch center; and initially spraying concrete to the mounting position.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a construction method using an arch installation machine. Background technique [0002] In the construction process of domestic mine roadways, railway and highway tunnels, water conservancy culverts, various underground projects, high-rise building foundation pits, military projects, etc., arch support tunnels are required. At present, the installation of steel arches in domestic tunnel construction is still mainly done manually or with the help of other equipment, which not only has relatively high labor intensity, but also cannot guarantee efficiency and safety. In order to achieve high-efficiency mechanized construction, arch installation machines were initially used. [0003] However, in the actual use of the wet spraying machine, there are the following problems: [0004] 1. The arch installation machine of the prior art only considers the clamping problem of the clampin...

AI Technical Summary

Problems solved by technology

[0004] 1. The arch installation machine of the prior art only considers the clamping problem of the clamping hand, but does not consider the clamping mechanics problem, and often causes fatigue stress damage after a long time of use, causing safety hazards

[0005] 2. In the arch installation machine of the prior art, the clamping hand uses a hydraulic cylinder to control the opening and closing, but the hydraulic cylinder is often external. Due to the angle of the external hydraulic cylinder, the component force of the clamping hand opening is small. Therefore, additional energy consumption is increased, and the external hydraulic cylinder increases the volume of the clamping hand; since the cylinder is straight and fixed on the clamping arm, the flexibility of the clamping arm is affected, so that the clamping arm cannot be flexibly bent

[0006] 3. The arch installation machine of the prior art only considers the functionality, but does not consider the problems of energy consumption, flexibility and installation

[0007] 4. The arch installation machine in the prior art often fixes the cables on the side of the hanging basket arm. However, this method is not suitable for the telescopic arm. The pipeline expands and contracts with the telescopic arm, and it is easy to cross the line.

[0008] 5. With the arch installation machine in the prior art, the hanging basket is lifted to the position and located on one side of the arch. If you think of the construction on the other side of the arch, you need to go in a "concave" shape, which greatly reduces the stroke efficiency and cannot be carried out on a high-precision scale. stroke operation

[0009] 6. The arch installation machine in the prior art has few degrees of freedom for the clamping module and the hanging basket module, and only realizes basic functions, and it is difficult to realize complex multi-degree-of-freedom actions through a simple structure; and the hanging basket is easy to tilt and unstable
