Single unit exceeds 200,000 square meters! Tunnel wet spraying with Wu Xin Equipment

In December 2022, in Daitian Tunnel of Wenyu Railway in Zhejiang Province, a Wuxin wet spraying machine with 9 years of experience is carrying out wet spraying operation. Under its weathered appearance, it hides the super high performance of the total spraying volume exceeding 200,000 cubic meters, which is the Wuxin No. 32 wet spraying machine.

Since leaving the factory in 2014, No.32 machine has served nine lines, including Xicheng Railway, Lalin Railway, Liuwei Highway, Baoping Highway, Chengkun Railway, Taijiao Railway, etc., and transferred to 15 tunnel sites in nearly 10 provinces, and made great achievements for the passage of many tunnels.

Durable and no overhaul

No.32 machine is a microcosm of the durability of Wuxin wet spraying machine.10 Over the past years, Wuxin wet spraying machine has been optimized in the design, manufacture and service to improve the stability of the equipment.

1. Manufacturing: dozens of processes carefully crafted, 28 quality control;

2. Commissioning: 60 hours of continuous commissioning to ensure high quality;

3. Performance: 7 generations of technology upgrade iteration, in-depth research and development and testing of core components, equipment life longer, lower loss;

4. Service: More than 300 service team members are on 24-hour standby at 52 after-sales service points across the country;

5.Quality: single concrete spraying capacity over 200,000 cubic meters, no overhaul in 5-6 years.

Second, continuous operation efficiency is high

High-intensity continuous operation and high construction efficiency have been the outstanding features of Wuxin wet spraying machines. Wuxin's No. 231 machine served in June 2016 in Changle Mountain Tunnel of Zhejiang Province's No. 1 longest tunnel, Qu-Ning Railway.

In order to catch up with the schedule, Wuxin wet spraying machine continuous construction in Changle Mountain Tunnel reaches up to 19 hours/day, and the single spraying concrete reaches up to 3200 square meters/month. 2018, Changle Mountain Tunnel achieves the whole tunnel passes through 40 days ahead of schedule.

Third, strong adaptation to extreme working conditions

Wuxin wet spraying machine has easily coped with a variety of harsh working conditions.

HaMu Passenger Dedicated Line: the lowest temperature is -27℃, and the length of bad surrounding rock accounts for 95%.

Xinjiang Afuzhun Railway: Located in a high-latitude and severe cold region, the railroad passes through a shallowly buried and soft surrounding rock geology, with the highest snowfall amounting to 94 centimeters.

Sichuan-Tibet Railway Yigong Tunnel: the longest railroad tunnel under construction in China (42.5 kilometers), with a maximum altitude of 4351 meters and a maximum depth of 1610 meters.

Xinjiang Wuyu Expressway Tianshan Shengli Tunnel: the world's longest highway tunnel under construction, with a maximum depth of 1112.6 meters, rock bursts, sudden water surges, and large deformation of soft rock.

Wuxin wet spraying machine has been on the market for 11 years, has won the Second Prize of Hunan Provincial Scientific Progress, the Second Prize of China Machinery Industry Technology 2022, and has been hammered with ultra-high reliability and durability in more than 2,000 tunnel construction sites, and has led the national sales volume for 7 consecutive years. In the future, we will continue to push forward the optimization and upgrading of our products, and provide customers with higher quality complete sets of intelligent equipment and services.
