The Tianjin Jinnan Xinzhuang Bay project is located in the Green Screen area of Xinzhuang Bay, Jinnan District, Tianjin, adjacent to the Guozhan Station of Metro Line It integrates RV camping accommodation, parent-child study tours, fishing and leisure, light dining, and tourist services, making it a benchmark cultural tourism project for suburban micro-vacations. As a core node of Tianjin's urban green ecological barrier, it relies on thousands of acres of wetlands, rice fields, and woodlands to create a "Senhuxi" (forest-breathing) cultural tourism camping site, encompassing various business formats such as luxury camping accommodations, tourist service centers, supporting commercial facilities, and public restrooms. Constrained by multiple factors including ecological control, tight schedules, high environmental protection and low-disturbance requirements, and the need for future layout adjustments, the project abandoned traditional brick-and-mortar construction and light-gauge steel container solutions, opting instead for the Hezhu modular building integrated solution. With factory prefabrication, full interior finishing, and complete hoisting delivery, it perfectly meets the development needs of suburban cultural tourism camping sites.

Core Project Constraints and Pain Points

Strict ecological red-line control: Located in the city's green ecological barrier, large-scale deep foundation excavation and permanent civil construction are prohibited, requiring minimal site disturbance and buildings that can be later dismantled and relocated.

High quality requirements for long-term outdoor use: The lakeside environment features high humidity, low winter temperatures, and frequent wind and rain. Containers are prone to rust, light-gauge steel offers poor insulation and soundproofing, and tents lack comfort, failing to support premium homestay pricing.

Strict environmental requirements for on-site construction: Strict control over dust, construction waste, and noise in wetland areas—the less on-site work, the better.

Flexible operational adjustments for later stages: The camping business will evolve with visitor flow; guest rooms and commercial units must be detachable, reconfigurable, and relocatable to different sites for reuse.

Core Selection: Advantages of Hezhu Modular Buildings

After multiple comparisons, the project adopted Hezhu's independently developed PC (precast concrete) modular buildings. Unlike traditional protruding-reinforcement and on-site assembled PC components, the core technology is specifically adapted to cultural tourism camping scenarios:

No on-site assembly required, zero damage during production, transport, and hoisting
Wall panels, floor slabs, and roof panels are all factory-prefabricated. Decorative finishes such as wall paint, flooring, and bathrooms are completed in the factory in one go. No protective measures are needed during transport, and no deformation or damage occurs during hoisting—suitable for long-distance transport from the factory to the wetland site.

Zero site damage, simple foundation requirements
No deep pile foundations are required; leveled and compacted ground is sufficient for placement, maximizing protection of existing wetland vegetation and soil, fully complying with ecological control requirements.

Full factory prefabrication, one-stop integrated delivery
All internal plumbing and electrical lines, insulation and soundproofing layers, doors and windows, fully equipped kitchens and bathrooms, and exterior finishes are completed at the factory. Each module is transported to the site as a complete unit, and a single building can be hoisted into position within half an hour—no masonry, plastering, or wet work on site.

Sturdy and durable structure, suitable for waterfront outdoor environments
Full concrete slab structure, Class A fire rating, resistant to winds up to Force 10, moisture-proof and corrosion-resistant, with no risk of steel rusting. Soundproofing is far superior to containers, greatly enhancing the guest stay experience.

Relocatable and recyclable
The entire modular building can be relocated to another site. When the campground adjusts its business format, expands, or relocates in the future, no secondary assembly is required, significantly reducing long-term cultural tourism investment costs.

Hezhu Complete On-Site Implementation Solution

Customized Modular Design

Based on the different functions of the camp's guest rooms, reception center, and commercial units, standardized unit modules are customized for each purpose and can be freely combined on site. The exterior finishes are simultaneously customized in two styles—wood-grain texture and fair-faced concrete—seamlessly blending with the natural landscape of wetlands and woodlands.

Full-Process Factory Prefabrication

All non-protruding-reinforcement PC components for walls, floor slabs, and roofing are mass-produced on Hezhu's automated production lines. Simultaneously, the complete interior system—including plumbing and electrical wiring, bathrooms, air conditioning, and lighting—is pre-installed. Interior flooring, cabinets, bathrooms, and thermal-break windows are fully assembled in one go at the factory, achieving a finished product upon delivery.

Rapid On-Site Hoisting and Turnkey Delivery

Finished modules are transported by truck to the Xinzhuang Bay campsite and hoisted into position using cranes. A single modular building can be fully installed within half an hour. No wet work is required, and no construction waste is generated.

Hezhu provides a full-chain service covering solution planning, component production, full interior finishing, logistics and transportation, on-site hoisting, waterproofing and joint sealing, and after-sales maintenance. We also assist clients with planning and fire safety approval documentation to ensure the project opens on schedule.

Suburban wetland, countryside camping, and other cultural tourism projects generally face four major challenges: strict ecological control, tight construction schedules, limited site conditions, and flexible and changeable business formats. Traditional building systems struggle to address all of these. The Hezhu modular building turnkey delivery system, with its core advantages of lightweight shallow foundations, full factory prefabrication, relocatability and reuse, and high outdoor durability, has become the optimal construction solution for cultural tourism campsites, rural homestays, and scenic area supporting facilities. Hezhu can provide customized PC modular building overall solutions tailored to various cultural tourism sites—wetlands, countryside, lakesides—offering one-stop turnkey delivery from planning, production, and finishing to on-site hoisting, helping cultural tourism projects achieve rapid implementation and long-term sustainable operation.
