Tunnel Formwork

Product Introduction

Tunnel formwork is an advanced construction system enabling one-time simultaneous casting of walls and slabs, forming a seamless cellular reinforced concrete structure. Ideal for repetitive cellular projects in standardized buildings (e.g., residential apartments, hotels), it streamlines construction by cutting labor, simplifying steps, and enabling fast daily pouring—outperforming traditional methods significantly. Widely used in modern construction, its housing-specific type is tailored for residential projects, abandoning the conventional "walls first, slabs later" approach to realize integral cast-in-place. This innovation boosts building stability and structural strength while shortening cycles, paired with reusability and low maintenance costs, making it perfect for large-scale residential developments and rapid-construction initiatives.

Product Advantage

High construction Efficiency：

Breaking the tedious cycle of "walls first, slabs later" with traditional steel formworks, our tunnel formwork system innovatively achieves simultaneous pouring of walls and slabs! Typically, the entire floor pouring process is finalized in just 5 days.

Superior Concrete Finishing：

Leveraging the integrated pouring technology of walls and slabs, the tunnel formwork fundamentally eliminates obvious splicing gaps in the concrete structure, creating a seamless structural texture. The formwork faceplate is customized with high-precision Q235B steel, ensuring the concrete surface after pouring is smooth, flat and delicate in texture—no need for extensive additional polishing. This not only enhances the exquisite appearance of the building but also reduces the workload and cost of long-term maintenance.

Modular Design, Reuse Quickly

The tunnel formwork adopts a modular structural design.the formwork’s assembly, disassembly and on-site adjustment are time-saving and labor-efficient throughout the process. Equipped with movable rollers at the bottom, it significantly reduces the frequency of on-site disassembly and assembly, improving turnover efficiency. Combined with a modular support system, it accurately distributes pouring pressure, effectively avoiding risks such as formwork collapse and displacement during construction.

All-Steel Structure, Durable and More Economical：

The tunnel formwork constructed with all-steel materials, and the core faceplate is made of high-quality Q235B steel. It boasts excellent structural strength, wear resistance and damage resistance, with a service life far exceeding that of traditional formworks—reusable for over 200 times. This greatly reduces the long-term procurement and replacement costs of formworks.
