Build "Steel Bar and Iron Bone" of Tunnel, New Arch Anchor Trolley of Railway Construction Heavy Industry Helps Plateau Railway Construction

January 29, 2024

Recently，At the construction site of a tunnel in Sichuan section of the plateau railway.，The new arch Anchor trolley of China Railway Construction Heavy Industry Co., Ltd. is carrying out professional and orderly installation of full-section multi-arch frames.、Welding of mesh connecting bars、A series of operations such as anchor construction，Forge the bones and muscles for the plateau railway。

Arch Anchor trolley construction site

It is understood that，Aim at solving that problem that the existing tunnel mechanical vertical arch operation has single function of equipment,、Large size、The weight is heavy、The operation is complex、Poor flexibility、Low construction efficiency and the like。Railway Construction Heavy Industry is problem-oriented.，Tackle difficulties and innovate，Developed with arch pickup、Arch frame transportation、Vertical arch operation、Anchor hole construction、Under-excavation treatment、Auxiliary charge、Installation of auxiliary anchor rod、Auxiliary reinforcement mesh welding and other functions are integrated.GM123A-FLSeries arch Anchor trolley。

The maximum operating height of the equipment is 12m.，Maximum working width 17m，Horizontal full-extension bearing capacity of middle arm: 3t，Horizontal full extension of left and right arms to carry 1 ton，The maximum drilling depth of single rod is 4m.。The equipment is suitable for steel arch.、Grid Arch、Articulated arch、Single arch frame、Multiple arches、Steel pipe grid、Lock the feet/System anchor bolt、Advance small conduit construction operation，Covering the whole section、Bench method and other construction methods。

2023 new product：GM123A-FLSeries arch anchor trolley

New product recommendation

Strong adaptability

3 Arm 3 Manipulator 2 Basket、2 Breaking hammer、Configuration of 3 welding machines，Undercutting and welding can be carried out during vertical arch operation.。Large-load-bearing rotary hanging basket，And is convenient to measure、Charging and installation of anchor bolt and anchor net。Multifunctional boom，It can automatically pick up and carry the arch frame to walk.。

And that construction efficiency is high

The carrying capacity of the boom is strong，It can complete the lifting and positioning of the full-section multi-arch frame of the high-speed railway double-track tunnel at one time，The construction efficiency is more than twice that of manual construction.。3-arm independent control，Feet can be locked synchronously when the connecting rib mesh is welded/System anchor construction，Save process connection time，Greatly improve the construction efficiency。

The construction quality is good

Horizontal full-extension bearing capacity of middle arm: 3t，Three-truss arch frame of full section of high-speed railway double-track tunnel capable of bee lifted by single arm at one times，The posture adjustment of the whole arch frame can be easily realized by the cooperation of the left and right arms.。

There are few construction personnel

The whole construction is carried out by traditional manual operation 12-13 down to 5-6 people。

Modular design

The modularization degree of the whole machine is high，The anchor bolt unit module is planned.、Welder module、Breaker module、Information module and other functional modules，According to different working conditions，Configure the corresponding module，Meet customer customization needs as much as possible。
