Project Background
In municipal road reconstruction projects, construction of special-shaped structures within narrow sections has long been a technical difficulty. In particular, pouring of curved curbs places extremely high demands on equipment flexibility and construction accuracy. Traditional construction methods tend to cause large alignment deviations, low construction efficiency and high rework rates, impairing the overall appearance and construction progress of roads. Faced with the challenge of constructing curved curbs in a narrow section during a municipal road reconstruction project, Yuantai Machinery delivered a customized slip-form construction solution to help the project achieve high-precision implementation with zero rework.
Project Overview
This project is a municipal road reconstruction initiative. The core construction difficulty lies in a narrow road section merely 3.8 meters wide, where curved curbs need to be poured with a minimum turning radius of only 5 meters. The project imposes strict requirements on curb alignment accuracy and surface flatness. Meanwhile, due to the narrow roadway, construction equipment must feature high flexibility to prevent damage to surrounding road facilities, and the construction schedule is tight.
Construction Pain Points and Challenges
At the early stage of the project, the contractor tried conventional formwork-pouring procedures and standard slip-form equipment, which exposed multiple on-site pain points:
-
1
Restricted working space in narrow sections. Conventional bulky equipment struggles to steer flexibly, prone to jamming and displacement, disrupting construction continuity.
-
2
Great difficulty in controlling the alignment of curved curbs. Traditional construction easily leads to excessive alignment deviation and uneven surfaces, requiring extensive later stage repair and rework and driving up construction costs and schedule pressure.
-
3
Cumbersome formwork-pouring process: massive manpower is consumed for formwork erection, resulting in low efficiency that fails to meet project schedule requirements.
-
4
Standard slip-form equipment cannot accurately adapt to the 5-meter minimum turning radius, often causing forming failure and concrete grout leakage and compromising construction quality.
To satisfy requirements for construction accuracy, efficiency and schedule, the contractor finally cooperated with Yuantai Machinery and adopted the customized slip-form construction solution for project execution.
Implementation of Yuantai Machinery’s Solution
Targeting the core requirements of narrow-section operation, curved curb forming and small turning radius, Yuantai Machinery’s technical team developed a tailor-made slip-form construction solution. Pre-construction simulation, equipment optimization and commissioning, plus full-process technical guidance jointly guarantee precise solution delivery.
Customized Equipment Configuration
Project Outcomes
- Qualified construction accuracy: Thanks to the customized solution and precise commissioning, curb alignment deviation is controlled within 1 cm, far exceeding project acceptance criteria. Surface flatness meets specifications and overall appearance satisfies municipal road construction standards.
- Improved construction efficiency: Abandoning the cumbersome traditional formwork erection process and adopting integrated slip-form construction greatly shortens the construction cycle and effectively relieves project schedule pressure.
- Zero rework achieved: Precise construction control and well-adapted equipment eliminate later-stage rework and repair, cut waste of concrete, labor and other resources and reduce overall construction costs.
- Reliable adaptability to working conditions: The optimized equipment perfectly adapts to the 3.8-meter narrow section and 5-meter small turning-radius operation without jamming or displacement, delivering safe and orderly construction.
Case Summary & Extended Value
The successful completion of this case fully demonstrates Yuantai Machinery’s technical strength and customized-service capability in constructing special-shaped structures for municipal roads. For complex working conditions such as narrow sections and small turning radii, Yuantai Machinery can accurately resolve construction difficulties via pre-construction simulation, customized equipment commissioning and full-process technical support.
